**** BEGIN LOGGING AT Sun May 26 02:59:58 2013 May 26 04:17:40 huh, no USB hotplug support on BBB Angstrom? May 26 04:17:45 * Shadyman headscratches. May 26 04:18:17 Shadyman, not for the uSD no May 26 04:18:40 they're working on it from what ive read on the groups by Gerald May 26 04:18:47 m_billybob: No, the USB :) May 26 04:19:02 migh be related ? May 26 04:19:05 idk May 26 04:19:07 maybe. May 26 04:19:14 USB kernel module perhaps May 26 04:19:25 kill it with fire! May 26 04:19:53 but yes, Gerald's answer was "Plug it in before booting up" to a guy's question re: a usb mouse May 26 04:21:14 well i saw a post by him saying they're working on uSD hotplug at the kernel level. or its on the list, but just assuming most / all uSD is sen by the OS as a USB port ? *shrug* May 26 04:21:36 i know all mine arelisted as USB devices May 26 04:21:46 x86 at least May 26 04:23:09 doesn't show in lsusb at all, so I dunno May 26 04:23:24 probably just teething pains with the new device system May 26 04:23:47 yeah, i kind of cant wait until 3-4 months from now May 26 04:24:00 im sure the playing field wil be much "richer" May 26 04:36:31 m_billybob, Shadyman I think that we should write up the USB issues on the ML and explain that Hotplug is a Major feature of USB and to not have it is untenable. ;) May 26 04:36:57 Depends if we want to get chewed a new one, I'd imagine. May 26 04:37:00 but it has to be an issue with the Angstrom..not Ubuntu or somethinge lese. May 26 04:37:22 USB depends on hotplugging May 26 04:37:26 truth May 26 04:37:34 no complaints ka6sox, and observation merely that im perfectly happy to work around :) May 26 04:37:41 an observation* May 26 04:37:49 its not something to work around, May 26 04:37:58 its fundamental to the way USB work.s May 26 04:38:33 http://armin762.wordpress.com/2013/04/28/the-new-beaglebone-black-and-gentoo/ May 26 04:40:04 seems to indicate it's more on a hardware level than an os level May 26 04:40:06 Shadyman by you ? May 26 04:40:11 nope May 26 04:40:18 armin76 May 26 04:40:35 is there a way to check if the firmware update has happened with the BBB ? May 26 04:41:06 bity: I believe the LED lights act as sort of a counter, goes from 1 to 5 May 26 04:41:12 don't quote me on that though May 26 04:41:28 they were all lit up May 26 04:41:46 it took a while and only the 1 chip on the board got warm May 26 04:42:10 ~50 minutes the user LEDs are all supposed to lite up, that what ive been reading May 26 04:42:18 ( when its finished ) May 26 04:44:32 https://groups.google.com/forum/?fromgroups#!topic/beagleboard/uWMNdBv_aPg May 26 04:45:20 ive only ever done an opkg upgrade, from 3.8.6 to 3.8.8. and only once, but ive since moved on to debian :) May 26 04:45:26 difference processs there May 26 04:45:54 different* May 26 04:46:53 what does it mean when all 4 lights are lit on the beaglebone black? May 26 04:49:04 in th context of flashing it means the image is finished flashing to emmc May 26 04:49:14 otherwise, i dotn know. May 26 04:49:32 and oooooops ---> " I reformatted the beaglebone blacks flash instead of my SD " May 26 04:50:11 bwuh May 26 04:50:12 "Your post has been sent for review and will appear after it has been approved." May 26 04:50:15 dammit google groups May 26 04:51:21 but I posted a reply to that thread May 26 04:51:47 damn May 26 04:53:07 because I'm getting no hotplugging at all. May 26 04:57:33 the uSD doesn't work at all May 26 04:57:38 for hotplug May 26 04:57:41 put it in before booting May 26 04:59:50 ^ May 26 05:00:01 ka6sox: http://dev.gentoo.org/~armin76/arm/beagleboneblack/install_emmc.xml#expand (another armin76 thing :)) May 26 05:00:08 was just reading the post on the groups again about the fella having issues with a USB hard drive not working on the bbb but it works fine in gentoo May 26 05:00:34 only thing i could think of is drive spin up not being handle as gracefully as on the desktop OS May 26 05:00:36 ka6sox: I got my 16GB microSD working by running that script and with a uEnv.txt on it May 26 05:00:54 ka6sox: was he trying to boot from it? May 26 05:01:06 ive had issues myself before with these cheesy 1A wal warts on USB drives, where the HDD inside needs 3As at spin up May 26 05:01:14 ^ May 26 05:01:35 I've got some that need the combined power from the computer and power from the wall to spin up May 26 05:01:46 yeah same here too May 26 05:01:53 which... isn't awful May 26 05:02:00 two plugs, and even then they dont work well May 26 05:02:12 onces we have here are pretty much garbage May 26 05:02:16 hehe May 26 05:02:29 drives come up as "needing scandisk" (windows ) all the time May 26 05:02:33 or as "no parition found" May 26 05:02:41 this is for 2.5" laptop drives . . . May 26 05:03:41 not a single problem with my external USB 3.0 drives though. full sized drives 3.5" May 26 05:03:53 WTF May 26 05:04:02 Somebody's bitcoin mining with cpuminer on the BBB? May 26 05:04:04 they're also externaly powered though May 26 05:04:06 That's... painful. May 26 05:04:13 520khash/s. May 26 05:04:19 * Shadyman boggles. May 26 05:04:27 you never gave that any thought Shadyman ? it was like the first thign i wanted to test myself wit hthe bbb May 26 05:04:38 m_billybob: No, because I knew it'd be silly. May 26 05:04:38 not with btc though May 26 05:04:45 ltc for me May 26 05:04:54 520 khash/s whereas my Radeon 5850 can do 370 Mhash/s May 26 05:05:14 heh my laptop with a 3400m APU does nearly 100 May 26 05:05:21 MH/s May 26 05:05:36 Not bad, if it swaps all the APU stream cores over the graphics instead of processing, yeah. May 26 05:05:38 i could see that May 26 05:05:44 ~86kh/s on light coins May 26 05:05:57 kitecoins* May 26 05:05:58 i've never taken the time to get LTC set up May 26 05:06:02 grr LITECOINS May 26 05:06:10 its pretty easy May 26 05:06:15 to set up, yes May 26 05:06:20 but to tweak? uck May 26 05:06:22 but it wil take your GPU way more May 26 05:06:27 tax* May 26 05:06:43 i can see ltc mining frying cards if you're not careful May 26 05:06:48 hehe May 26 05:07:33 tweaking is prety easy just a couple mor params compared to btc, and you do not necessarily ned to use them May 26 05:07:37 now a BBone with a bunch of Virtex7 chips, I could see. May 26 05:07:44 i use BFGMiner btw May 26 05:07:46 yeah May 26 05:08:04 but you can double or halve your ouput by using the wrong (or default) params if they're not right May 26 05:08:06 i havent mined in a coupe weeks though May 26 05:08:18 it's a lot easier to get wrong, let's say May 26 05:08:21 my best laptop is also my dev platform now do yeah... i need my system lol May 26 05:08:26 lol May 26 05:08:42 So... SD card capes :3 May 26 05:08:42 i was just doing it as kind of a test May 26 05:08:56 waiting for a sunny day to reflow my sd card cape prototypes May 26 05:09:11 was considering buying a 7950 put it in my desktop and lettign it run 24/7 May 26 05:09:46 it wont make me rich but after a year it could end up paying for its self and buying me a new better laptop May 26 05:10:18 Assuming you find a way to get your money out May 26 05:10:27 we're solar power so no energy bill to worry about May 26 05:10:33 as Mtgox's Dwolla account was siezed by the US May 26 05:10:50 is that the main body of mygox ? May 26 05:10:55 mtgox* May 26 05:11:03 well, the US$ funds, I'd imagine May 26 05:11:07 or, the majority. May 26 05:11:14 it's hard to say May 26 05:11:14 wonder how that is possible May 26 05:11:23 i'd imagine they would have withdrawn most for safekeeping May 26 05:11:37 i mean yes the government can do whatever they please now days it seems, but how could they legally do that ? May 26 05:11:58 oh, I'm sure they came up with something interesting like money laundering, suspected wire fraud, etc, etc May 26 05:12:04 drug/arms trade May 26 05:12:27 perhaps they think mtgox is behind all the supposed ddos fund day trading crap going on lately ? May 26 05:12:30 http://techcrunch.com/2013/05/16/mt-gox-dwolla-account-money-seizure/ May 26 05:13:11 well that's a bit clearer. May 26 05:13:29 aka "Oops" May 26 05:13:52 btc is actually up to $133 per now too lol May 26 05:14:03 * m_billybob just check coinify May 26 05:14:31 yeah May 26 05:14:39 down from 260 though ;) May 26 05:14:41 homeland security thats all i need to read May 26 05:14:48 ^ May 26 05:14:50 this is purely political i can rtell already May 26 05:15:36 so what exactly is dwolla ? May 26 05:15:45 are they the main backers behind mtgox ? May 26 05:16:21 says uts because they failed to register as a money transmitting company May 26 05:17:53 dwolla is kinda like paypal May 26 05:18:00 ah May 26 05:18:19 you could easily transfer funds from a us bank account to dwolla May 26 05:18:24 and then send a payment from dwolla to mtgox May 26 05:18:26 see i mine ecoins but dont really follow the news or information on it May 26 05:18:35 the way i see it is like this May 26 05:18:45 its all monompoly money, until i cash it in May 26 05:18:48 yeah May 26 05:19:04 (or they go belly up) May 26 05:19:31 well that goes without saying it means nothign to me until its in my pocket May 26 05:19:48 hehe May 26 05:19:58 so hmm May 26 05:20:27 wonder how hard it would be to trade for prepaid CC now, im vaguely remembering that maybe dwolla had somethign to do with that ? May 26 05:20:39 oh well May 26 05:20:55 .dunno May 26 05:20:59 HURG May 26 05:21:06 cat has my socked foot in his grasp May 26 05:21:15 so heres the big question May 26 05:21:23 problem solved, he gave it up so he could lie upside-down May 26 05:21:40 they're affraid the btc is being used to launder real money or to be used to buy drugs May 26 05:21:54 yes May 26 05:21:55 so like if the "real" us currency is being used to to the same ? May 26 05:22:09 at least "real" currency is easy enough to track May 26 05:22:33 paper trails and such May 26 05:22:49 well bigger point to me is that both are going ot happen no matter what currency you use May 26 05:22:55 yeah. May 26 05:23:02 but one does not simply GET $500,000 USD without someone knowing about it. May 26 05:23:05 yeah idk May 26 05:23:11 ;) May 26 05:23:12 this is why i hate politics. May 26 05:23:18 its al BS in the end anyhow May 26 05:23:21 hehe May 26 05:24:12 ive had a few beers today and am kind of snippy so never mind me lol May 26 05:24:27 oh well May 26 05:27:00 yeah . . . May 26 05:32:44 just trade your btc for gold with coinabul May 26 05:32:57 trade one non-dollar for another non-dollar May 26 05:43:06 makes sense May 26 05:58:48 hi, is mainline kernel the best for BeagleBoard xM ? (i would be able to use GL, DSP, etc) May 26 06:39:04 <_av500_> spenser309: the angstrom kernel is the best May 26 06:39:10 <_av500_> the one that ships with it May 26 06:44:11 <_av500_> coffee May 26 07:43:08 Ciao May 26 07:43:13 !list May 26 07:43:55 <_av500_> SYNTAX ERROR May 26 07:46:28 mdp: any idea how/where is hwmod data auto generated? May 26 08:04:47 * Shadyman ponders a daisy-chain of BBones May 26 08:05:06 CHALLENGE ACCEPTED. May 26 08:05:09 here goes May 26 08:06:27 haha, cute. It takes time for the first one's USB Host power to kick in, so the second one's delayed a bit. But still, bring on the beaglechain ;) May 26 08:19:27 I am just starting with black board. In one of the videos it implies that I can directly toggle I/O lines from the command line in an SSH session. Where should I look for examples? May 26 08:20:16 I'd guess that's toggling the stuff in sysfs May 26 08:22:43 I'm real new to this (minimal Linux experience) is sysfs a file, a program, something else? May 26 08:28:03 fliptron: https://www.kernel.org/doc/Documentation/gpio.txt if sysfs May 26 08:33:01 Defiant: Thanks, this is the type of info I wanted. This looks like C callable functions, which I can do within a program. I'll go read docs carefully. May 26 08:35:13 fliptron: the c-stuff is for in-kernel access, not userspace May 26 08:37:28 Ok, for a lowly user, are there commands at the Linux prompt (in an SSH session) that let me wiggle pins? May 26 08:37:46 fliptron: scroll down to the userspace/sysfs part May 26 08:40:57 so basicly from ssh you can do something like echo 1 > /sys/class/gpio/gpioN/value May 26 08:42:43 Thanks for the clarifying example. This should be enough to get me going and having some fun. May 26 08:42:58 what's the application for this May 26 08:43:14 :) May 26 08:43:52 hah i ruined my bbb May 26 08:44:05 bad idea for upgrade so there it went May 26 08:45:13 Ketas: I'm just getting started with bbb, and I want to wiggle some pins so I have a sense of accomplishment. Later I am sure it will be very useful when doing debug of my projects May 26 08:49:41 i plan to get more beaglebones for my ip <-> io needs in my house May 26 08:53:47 ketas, how'd u brick the bbb? May 26 08:54:53 brick brick or just overwrite the OS in eMMC brick? May 26 08:55:08 you can't brick it May 26 08:55:19 the only way is to make the magic smoke escape May 26 08:55:20 you can always brick it, just apply 230V ;) May 26 08:55:28 * dm8tbr high-fives kfoltman May 26 08:55:29 is there memory in soc? May 26 08:55:34 that one can overwrite? May 26 08:55:41 mask-rom :> May 26 08:56:04 a steady hand and a high powered laser... May 26 08:56:09 hahaha May 26 08:56:17 dm8tbr: well, the ADC pins apparently have a limit of 1.8V, and I think the GPIO pins are non-5V-tolerant... :S May 26 08:57:20 time for optocouplers May 26 09:01:03 kfoltman: yes, the good thing is that this is all well documented :) May 26 09:01:36 bity: opkg upgrade :P May 26 09:01:53 could someone put in the channel topic, "opkg upgrade may brick your BBB"? :D May 26 09:02:04 i knew that May 26 09:02:10 =/ May 26 09:02:13 still, some might not May 26 09:02:15 * kfoltman <_ May 26 09:02:20 <- even :) May 26 09:02:24 i knew something will go wrong May 26 09:03:01 well is there proper incremental upgrade? May 26 09:03:05 ketas: if you can get to uboot (that happened to me), then you can boot from USB pendrive or microSD May 26 09:03:39 ketas: I don't know of any 'proven working' upgrade, some people had a hack to make opkg upgrade work better, but I forgot what it was :S May 26 09:04:14 but you need a TTL serial cable to talk to uboot May 26 09:04:32 i have multiple May 26 09:17:42 ketas: see if you can use the kernel from a pendrive with rootfs on eMMC May 26 09:19:01 some time later May 26 09:19:10 no free usb flash either May 26 09:19:51 hi all May 26 09:20:59 many sd cards and reader, though May 26 09:21:33 that's the same thing May 26 09:31:24 somehow, i don't have stash of usb flashes May 26 09:33:47 some have... they even use usb flash to transfer files in lan May 26 09:33:56 i was like wtf when i heard May 26 09:35:38 sneakernet 2.0 May 26 09:48:39 sneaky May 26 09:50:43 before bbb still worked, i noticed that it doesn't like http over ipv6 May 26 09:50:55 weird May 26 09:51:14 noone ever tried that? May 26 09:51:34 because noone has ipv6 anyway? :) May 26 09:51:48 except some like me who have had it over 10 years May 26 10:01:57 ketas: ipv6 at home is still very rare May 26 10:02:05 ketas: only a few fortunate have it May 26 10:02:24 ketas: big isps are still very reluctant to provide ipv6 unless you are a big customer and have lots of $$$ May 26 10:02:39 ketas: or you are the other kind of unfortunate and dont have a bbb ;) May 26 10:03:58 hah May 26 10:04:09 well this is not native yet, sure May 26 10:05:01 i ask for ipv6 some times a year, always isp says that no client tests planned because ipv4 is not full yet May 26 10:05:13 lol May 26 10:05:22 support is there they say May 26 10:05:24 let me gues,.. you live in the us? May 26 10:05:36 estonia in europe May 26 10:05:42 mru: wtf?? May 26 10:05:54 mru: you've been on these weird art websites again? May 26 10:06:01 ketas: o_0 May 26 10:06:27 not yet full May 26 10:06:30 :P May 26 10:06:38 ketas: ripe wen't into we-dont-give-you-any-ipv4-addresses-unless-your-live-depends-on-it mode last summer May 26 10:06:46 KotH: I saw the real thing in a gallery May 26 10:06:56 what? May 26 10:07:24 mru: who would even think of buying something like this? much less put it on public display? May 26 10:07:28 KotH: maybe teliasonera has collected a lof ot ranges May 26 10:07:32 :) May 26 10:07:48 of May 26 10:08:01 KotH: dali, apparently May 26 10:08:28 it's one of a series of 12 or so May 26 10:08:35 0_0 May 26 10:08:40 KotH: i wonder when i will finally get native ipv6, would i get my /48? May 26 10:08:50 if i want May 26 10:08:53 ketas: i have my native /48 already ;-> May 26 10:09:17 mru: art... one must not understand it... May 26 10:09:32 because you know, homes now have multiple networks... May 26 10:09:35 more in future May 26 10:10:15 ketas: this is at home :) May 26 10:10:25 somehow reminds hipnet presentation from ripe 66 May 26 10:10:50 but multiple /64's seems too wasteful?! May 26 10:12:15 well.. you dont need to pass /48's around, a /60 will be more than enough for 99.999% of all home users May 26 10:12:34 likely May 26 10:13:06 bonescript does have ipv6 support May 26 10:13:09 about 2**68 devices? you want to address individual neurons or what? May 26 10:13:12 that's how I use it at home May 26 10:14:41 most users don't have 65535 separate networks at home May 26 10:16:04 kfoltman: that's not how ipv6 works May 26 10:16:27 kfoltman: the lower /64 are needed to get your machine an ip (it is derived from the mac address) May 26 10:16:28 KotH: but CHOCOLATE! May 26 10:16:53 mru: i rather have good swiss chocolate. that's more my kind of art ;) May 26 10:16:54 KotH: how stupid is that? May 26 10:17:05 mru: ipv6? dunnno May 26 10:17:08 time will tell May 26 10:17:15 what if I replace the nic? May 26 10:17:22 and each containing billions of v4 space equivalents May 26 10:17:26 mru: replicate? May 26 10:17:27 hah May 26 10:17:32 ipv6 is too big May 26 10:17:40 mru: that's why ipv6 addresses are designed to not be easily memorized ;) May 26 10:17:56 no, but dns... May 26 10:18:05 mru: if you mean putting two NICs into a machine with the same mac, that works as expected May 26 10:18:12 is ttl of 5min the way? May 26 10:18:24 mru: two different machines with NICs with the same MAC are not allowed by 802 anyways May 26 10:18:49 unless some chinese nic factory counter gets stuck May 26 10:18:55 like it happened here somewhere May 26 10:19:01 * KotH has not had the time to look how ipv6, dynamic ips and dns updates work together May 26 10:19:04 box of nics, ALL SAME MAC!!! May 26 10:20:34 sounds like fun May 26 10:21:08 i bet it was for those guys who had to install, then reinstall them in school May 26 10:21:47 it became problem when only one machine got ip from dhcp at any given time May 26 10:22:09 one machine? May 26 10:22:16 then something is wrong with their network May 26 10:22:23 all machines should have gotten the same ip May 26 10:22:29 :P May 26 10:22:53 hmm... unless the "check whether ip is already used" system of dhcp works properly in that case May 26 10:23:49 mru: well, what May 26 10:24:24 mru: um well May 26 10:24:42 servus mhaberler May 26 10:24:50 hi!

May 26 10:25:33 ketas: most people name their machines in a meaningfull way May 26 10:27:11 where you need meaningful name you maybe choose meaningful ip too, manually May 26 10:28:02 although i give all my own ipv6 addresses out with ra and try to use those resulting addresses in dns May 26 10:35:08 KotH: ever heard of a public web server?

May 26 11:02:53 KotH: I use it for all sort of status notifications May 26 11:03:19 dm8tbr: i can understand its use for seldom notifications over the internet.. but for anything else? May 26 11:03:47 and I'm seriously pissed as I can't use XMPP clients to connect to google apps any more. at least it seems unreliable May 26 11:04:08 eh.. they still run their own version of xmpp? May 26 11:04:41 it seems they broke it now intentionally May 26 11:04:49 i doubt it May 26 11:05:11 google coders just done have time and patience to try non-google software with their services May 26 11:05:32 and they break stuff often and continously May 26 11:05:53 you should once listen to people working at google, how often even mail and calendar is broken for them May 26 11:06:31 well they declared 'we don't care about XMPP' and only focused on their 'hangouts' product May 26 11:06:46 that's very close to deliberately breakint it May 26 11:07:01 eh.. May 26 11:07:03 drop them May 26 11:07:10 use a different jabber service May 26 11:07:13 work requirement May 26 11:07:13 there are tons of them May 26 11:07:29 I can't use my work phone to be reachable as it's not android May 26 11:07:46 is that a problem? ;) May 26 11:08:10 if you actually want to get work done, yes May 26 11:12:45 you need jabber for work? May 26 11:20:25 yes May 26 11:21:07 lol.. homeland security is worried about the uncontrolled distribution of guns using 3D printers May 26 11:21:28 actually it seems like right now sending messages while XMPP clients are connected to a google apps account results in those receiving messages too May 26 11:21:39 KotH: they must be kidding May 26 11:22:58 ketas: home printed weapons of mass destruction... serious business May 26 11:23:28 KotH: ban 3d printers!

May 26 12:41:25 id like to see whats the problem May 26 12:41:33 connect a serial cable to the bone May 26 12:41:40 or whatever you are using May 26 12:41:48 of the complete boot procedure May 26 12:41:55 im using black May 26 12:42:16 theres a special serial cable needed, or? May 26 12:42:32 just standard lvcmos signal level serial May 26 12:42:58 dont have an serial cable that fits to those serial pins May 26 12:42:58 use any ftdi usb cable you've lying around May 26 12:43:03 ^^' May 26 12:43:07 i dont have one :/ May 26 12:43:24 go buy one May 26 12:43:26 :) May 26 12:43:29 you will need it May 26 12:43:43 the more you do with electronics the more you will need it May 26 12:43:50 it's like having a soldering iron and a multimeter May 26 12:44:37 im not sure where i can buy it May 26 12:44:39 here in germany May 26 12:44:53 just saw some to be ordered in usa May 26 12:45:42 try olimes May 26 12:45:45 olimex May 26 12:45:48 they are nearer May 26 12:46:09 and you dont want to found those who fight a war against the just JIHAD, do you? May 26 12:48:48 cant i output to usb? May 26 12:49:02 not the stuff you are looking for May 26 12:49:27 what could be my problem? May 26 12:49:28 :/ May 26 12:49:38 anything May 26 12:49:44 from lack of chocolate to cosmic rays May 26 12:50:20 lol :D May 26 12:50:34 what does control the LED's? May 26 12:50:51 have you had a look at the schematics? May 26 12:51:04 yes May 26 12:51:09 then you know May 26 12:51:12 i May 26 12:51:33 have you ever heard of somebody trying CE on that Black? May 26 12:51:45 windows ce? May 26 12:52:00 yes May 26 12:52:30 ask your friendly TI representative May 26 12:52:33 i dont think anyone in his right mind would do something masochistic as that May 26 12:53:07 i dont get why everyone is against it :/ May 26 12:54:02 because windows is a pain on the pc already. guessing from how much work it is to get linux working on an embedded system, where you have full sources and total control over everything, i dont want to imagine what a pain it is to get windows working May 26 12:54:33 * dm8tbr remembers when that microsoft guy joined in here after buying 10 bb-classic and asked how to enable the HS feature :D May 26 12:54:49 HS? May 26 12:54:56 high-security May 26 12:55:00 lol May 26 12:55:01 aka signed MLO May 26 12:55:22 <_av500_> Tey: they can be bought in germany too May 26 12:55:37 where? May 26 12:55:37 <_av500_> Tey: and no need for PM May 26 12:55:44 anyone got a decent report for the beaglebone black running slackware? May 26 12:56:15 trying to determine if I'm ready to order one yet.. May 26 12:56:21 <_av500_> http://www.watterott.com/de/FTDI-Basic-Breakout-5V May 26 12:56:24 <_av500_> Tey: ^^^ May 26 12:56:27 youre right anyway, windows is a pain May 26 12:56:31 <_av500_> just note that it does not fit May 26 12:56:34 <_av500_> mechanically May 26 12:56:41 <_av500_> so you need to extend the pins May 26 12:56:47 <_av500_> or solder a 6pin on the bottom May 26 12:56:59 ._. May 26 12:57:24 <_av500_> http://www.watterott.com/de/FTDI-Basic-Breakout-3V3 May 26 12:57:29 <_av500_> this one, 3.3V May 26 12:57:58 none in stock May 26 12:58:08 <_av500_> indeed May 26 12:58:16 <_av500_> try reichelt or conrad May 26 12:58:18 there is a reason why people have ftdi's with rx/tx/gnd on single wires on their desk :) May 26 12:58:39 <_av500_> KotH: or just he 6pin header May 26 12:58:45 <_av500_> and the chip in the usb plug May 26 12:58:52 <_av500_> we bought like 20 at work :) May 26 12:58:57 *g3 May 26 12:59:05 http://de.rs-online.com/web/p/entwicklungskits-interface/6877780/ May 26 12:59:08 that one should fit the bill May 26 12:59:30 <_av500_> Tey: thats the one May 26 13:00:02 reichelt, where expensive things are even more expensive May 26 13:00:52 but how do i connect over it? May 26 13:01:02 with a driver? May 26 13:01:12 virtualizing that USB as a COM port? May 26 13:01:25 uh.. you are using windows? May 26 13:01:33 uhmm... yes, you will get a com port May 26 13:02:08 driver is standard and should be already installed.. unless you plug it in somewhere, were no ftdi has been plugged in before.. or you plug it in somewhere else May 26 13:02:35 do yourself a favor and get a linux box if you wan to do any serious embedded linux development May 26 13:02:41 it makes life easier.. a lot easier May 26 13:04:26 i want to do some serious embedded windows development May 26 13:04:28 :] May 26 13:04:47 ah.. you are into BDSM, then windows as a desktop is the right choice ;-) May 26 13:04:51 so the cable will automaticly connected as Serial Port? May 26 13:05:07 you are new to electronics, are you? May 26 13:05:18 yes, it will be recognized as a serial cable May 26 13:05:24 yes, it might ask for a driver May 26 13:05:28 yes, just click trough it May 26 13:05:44 yes you will have to set the right baud rate too May 26 13:12:13 <_av500_> windows needs the ftdi driver May 26 13:12:27 <_av500_> but google knows all about that May 26 13:18:15 av500, does that cable fit to that driver? May 26 13:18:18 from RS? May 26 13:18:37 Tey: koen's rule #3: just try it May 26 13:18:39 Tey: alternative to RS is Farnell -- http://de.farnell.com/ftdi/ttl-232r-3v3/kabel-usb-ttl-pegel-seriell-umsetzung/dp/1329311 May 26 13:18:39 is it the same, like the ones refered in beagle wiki May 26 13:19:59 thanks fiola, but its the exact same like on RS isnt it? May 26 13:20:20 Yep, same produict from FTDI that the peeps mentioned May 26 13:20:50 I have it working here with Black, it's good. May 26 13:21:01 allright May 26 13:22:29 It's one of the accessories specified on the BBB page, so hard to go wrong -- http://de.farnell.com/circuitco/bb-bblk-000/beaglebone-black-cortex-a8-e-board/dp/2291620 May 26 13:22:57 I use UK site, but it's identical to DE site. May 26 13:23:21 does BB actually need special SD's? May 26 13:23:34 tested two, one 4gb and one 265mb May 26 13:23:44 maybe thats causing my boot problem? May 26 13:24:54 I haven't tested yet, about to try a 4G SanDisk. Whenever I have trouble with SD it's a SanDisk, so might have "fun" and end up chucking it. May 26 13:26:25 I also bought the Transcend that Farnell list as a BBB accessory, so that should be expected to work. May 26 13:27:13 why not just walk into the next shop and buy some cheap chinese shit? May 26 13:27:30 buy 10, if 8 work you're fine May 26 13:27:46 and have saved 50% of your money May 26 13:28:02 Worth trying, hehe. What's the typical price on known chinese crap? May 26 13:28:11 unknown* May 26 13:28:58 starts from "vevy cheap, original, high quality" and goes to "high quality, vevy cheap" May 26 13:29:05 <_av500_> Tey: FTDI is FTDI May 26 13:29:07 got a fujitsu sd May 26 13:29:11 <_av500_> from bot RS and Farnell May 26 13:29:34 yep thanks av500 May 26 13:29:35 <_av500_> Tey: please, as long as you have no way to get boot log, stop wasting our time May 26 13:29:53 yes sir May 26 13:30:06 .o0(braves hündchen) May 26 13:30:17 ill be wasting your time when i got my logs ^.° May 26 13:30:32 Tey: don't worry about _av500_, being offensive is his spoeciality here :P May 26 13:30:45 No its okay May 26 13:30:48 i mean hes right May 26 13:31:06 <_av500_> fiola: you find that offensive? May 26 13:31:11 fiola: if you think av500 is offensive, what do you think about the rest of the people here? May 26 13:34:57 KotH: I guess everyone has their day off sometimes. It's still a helpful place, just needs some displomacy in putting your questions right, and someone in a helpful mood will usually answer. Can need patience. May 26 13:35:32 <_av500_> fiola: yes, but he is asking for a week now May 26 13:35:35 <_av500_> always the same May 26 13:35:42 <_av500_> and we told him like 5 times to get serial logs May 26 13:35:51 Uh oh. May 26 13:36:17 but at least he doesn't have Alzheimer's... May 26 13:36:31 * vvu hides during these times May 26 13:37:47 under a bridge? bad choice! ;) May 26 13:38:44 in plain sight! May 26 13:39:17 Worth noting that because of the price point, the BBB will attract many less technical people as it becomes known more widely. That means questions will become worse over time as beginners flood in. May 26 13:39:42 fiola: we know that already May 26 13:39:49 <_av500_> luckily very few of them will want to install Windows CE on it May 26 13:39:54 Hahaha May 26 13:39:55 fiola: we have felt it in the first week, when the channel was flooded May 26 13:40:44 _av500_: as someone else mentioned, BDSM is a popular partime, so don't count on it :P May 26 13:40:54 and actually, i assume someone engaging in running windows ce on a bbb knows a bit about embedded electronics and knows how to do stuff May 26 13:40:55 passtime* May 26 13:42:53 hi guis cn u help me do a windos ce project for skool plz? May 26 13:42:56 j/k May 26 13:43:12 kfoltman: ask your supervisor for a real project May 26 13:43:18 love the spelling :P May 26 13:43:38 <_av500_> kfoltman: do I like me, copy from your clasmate May 26 13:43:40 <_av500_> classmate May 26 13:43:47 <_av500_> do it* May 26 13:43:53 intel classmate? May 26 13:43:53 <_av500_> cant spell today May 26 13:43:59 <_av500_> kfoltman: yep for windows May 26 13:44:35 _av500_: that explains how you got into all that tablet business... if you would have done your homework, and learned something in school.... ;-) May 26 13:44:44 <_av500_> ... May 26 13:44:46 <_av500_> :effort: May 26 13:46:19 speaking of dumb questions, I'm stuck with one thing, no trolling this time: I made a 96M ext2 rootfs and made a compressed image using mkimage. I'm loading it at ${rdaddr} using fatload and then run a kernel using this ramroot value: /dev/ram0 rw ramdisk_size=98304 initrd=${rdaddr},96M. The kernel starts and panics due to "Unable to mount root fs on unknown-block (1,0)". Did I do something stupid? May 26 13:46:41 well, using gzip and the mkimage, of course May 26 13:47:36 it previously worked with cramfs, but I didn't like my root fs being readonly (and yes, ramrootfstype is set correctly, to ext2) May 26 13:47:52 kfoltman: have you compiled ext2 support into your kernel? May 26 13:48:24 IOW module won't do. May 26 13:48:44 Koth: <*> Second extended fs support <- sounds like a yes May 26 13:48:56 hmm.. May 26 13:49:35 ext2/ext3/ext4 all compiled in, and the rootfs is old ext2 anyway May 26 13:50:18 do you have any other error? May 26 13:50:23 warning or the like? May 26 13:50:35 like initrd support missing May 26 13:51:18 no, and it worked with cramfs before anyway, same kernel May 26 13:51:25 strange May 26 13:51:38 * KotH has no experience with initrd, as he usually uses initramfs May 26 13:53:02 KotH: why? are you using separate boot and root fs'es? (my system doesn't probably need that separation) May 26 13:53:08 http://pastebin.com/6vV9d1CS in case there's something meaningful in it May 26 13:53:21 nope, just one fs May 26 13:53:55 initrfamfs is slightly more compact in memory, and slightly more efficient, that's why i use it May 26 13:54:47 meaningles pastebin is meaningles May 26 13:54:48 http://pastebin.com/i1cMa5Hx ok, this has more context May 26 13:55:29 hmm.. May 26 13:55:43 what does the kernel do in the first 0.8s? May 26 13:56:29 don't know, draws a Tux on HDMI framebuffer? ;) May 26 13:56:48 I just received by BBB and followed the suggested update procedure, writing the image file to a uSD card and programming the eMMC. The operation finished with all board LEDs constantly lit, but now the beaglebone does not boot anymore. Only the power LED turns on May 26 13:56:52 what can I do? May 26 13:57:03 eject the sdcard May 26 13:57:11 I have May 26 13:57:30 connect up a usb-ttl serial device and watch what is going on May 26 13:57:44 Rickta59: lvcmos, not ttl May 26 13:57:53 Rickta59: ttl signal levels will fry the cpu May 26 13:57:56 a 3.3v usb serial device May 26 13:58:10 I'm afraid I don't have one May 26 13:58:17 time to order May 26 13:58:51 you could just download a bootable image May 26 13:58:57 and boot from the sdcard May 26 13:59:04 I will try that May 26 13:59:05 thanks May 26 14:00:53 Could use one BBB as a console interface for another :P May 26 14:01:26 or a beagleboard May 26 14:01:48 eh.. May 26 14:01:49 Aye, anything with 3v3 serial May 26 14:02:07 dm8tbr: we actually use arm7's for this kind of stuff at times :) May 26 14:02:21 :) May 26 14:03:20 <_av500_> what a waste of a perfectly good arm7 May 26 14:04:01 they're getting to be a dollar now May 26 14:04:06 should we have used msp430s? :) May 26 14:04:37 i've had good luck with those $7 ebay ftdi chips May 26 14:04:39 would this usb2serial connector work? : http://andre.blaatschaap.be/2013/01/cubieboard-serial-connection/ May 26 14:05:08 yes May 26 14:05:10 <_av500_> yes May 26 14:05:15 <_av500_> order 20 May 26 14:05:21 <_av500_> keep one, resell the others here May 26 14:05:28 <_av500_> 4) profit May 26 14:05:38 lol May 26 14:05:41 I already have that one I just found out :) May 26 14:05:49 what about the 5v pin?

May 26 14:16:38 I thought those were cheap nowadays due to being commonplace in scrapped BTSs etc May 26 14:16:49 nope, they aren't May 26 14:16:55 Rb frequency standards are cheap May 26 14:17:02 ah May 26 14:17:12 that Cs standard even contained a BVA oscillator (the lowest noise oscillator known to men) May 26 14:17:12 mixed those up May 26 14:17:34 and he is trying to sell the BVA for 4k5USD May 26 14:20:48 Mourning Ladies and Trolls (and Trollettes?)

May 26 14:25:06 ka6sox: i dont go anywhere w/o a pack of chocolate May 26 14:25:13 ka6sox: just ask dm8tbr or av500 :) May 26 14:25:30 * dm8tbr can confirm that May 26 14:31:59 dm8tbr: FE-5680a are currently 80usd on ebay May 26 14:32:10 (ie price comming down again) May 26 14:34:00 KotH, if I'm going to fly 5136 miles My wife wants to know that there is chocolate at the other end. May 26 14:34:14 lol May 26 14:34:22 ka6sox: i can make sure you get some May 26 14:34:33 ka6sox: there are ways to deliver high qual swiss chocolate :) May 26 14:34:57 KotH, her answer: "Any time now is fine!" May 26 14:35:22 * KotH doesnt ship food to the us May 26 14:35:37 there are too many customs officiers waiting to get his explosives May 26 14:36:10 Hi. Is there somebody living in Berlin having some BeagleBones? May 26 14:36:52 given the fact that there are 3.5 mio people in berlin.. i'd say the chances are high May 26 14:36:57 And who could borrow them to the coreboot hacker meeting today and tomorrow? May 26 14:37:22 that might limit the number... May 26 14:37:24 those chances are quite considerably lower May 26 14:40:08 PaulePanter, I'd send email on this too...(ph0rums/googlegroups whatever they are called) May 26 14:42:15 <_av500_> PaulePanter: ask janne May 26 14:42:42 janne_: Hi. Can May 26 14:42:45 … y May 26 14:43:05 you borrow a BeagleBone to the coreboot summit today or tomorrow? May 26 14:43:13 Thanks to all the others. May 26 14:44:21 <_av500_> PaulePanter: https://plus.google.com/100303819724311361864/posts/7HajyjoDp65 May 26 14:44:24 <_av500_> see, he has 2 :) May 26 14:45:10 Trying to get Arch on my BBB, I'm at the step of moving the arch fs onto the eMMC from an SD card, the files start transferring and at a some point the BBB will power off before I can extract the fs. May 26 14:45:34 oh my god, this device trees are complicated May 26 14:45:46 <_av500_> tdilly: why not leave it on the sdcard May 26 14:45:46 Anyone have Arch on their BBB rev A5A? May 26 14:45:52 <_av500_> just ignore the emmc May 26 14:45:58 <_av500_> boot from SD May 26 14:46:02 <_av500_> its much easier for tinkering May 26 14:46:07 _av500_: I don't want to hold the boot button down to boot into it May 26 14:46:13 <_av500_> you dont need to May 26 14:46:19 <_av500_> just kill MLO on the emmc May 26 14:46:24 <_av500_> and it will boot from the sd May 26 14:46:47 * _av500_ feels like beagle Classic all over again May 26 14:47:00 _av500_: It's going to have to now because there is now a half transferred arch on the eMMC root May 26 14:47:10 <_av500_> so? May 26 14:47:12 <_av500_> boot from sd May 26 14:47:15 <_av500_> and kill MLO May 26 14:47:45 _av500_: but shouldn't I be able to update the eMMC? May 26 14:47:48 _av500_: I wondered why they went for fixed storage again... May 26 14:47:52 <_av500_> timm: no, DTs are simeple May 26 14:47:54 <_av500_> simple May 26 14:47:59 <_av500_> all the Macs use them May 26 14:48:03 <_av500_> so it must be easy May 26 14:48:11 <_av500_> jsobs would never made it complicated May 26 14:48:15 <_av500_> sjobs* May 26 14:49:32 To decrease chances even more, I just heard, they need just the BeagleBone and not the Black one. (So the predecessor.) May 26 14:49:52 <_av500_> thats mostle the same May 26 14:49:54 <_av500_> mostly May 26 14:50:13 <_av500_> in terms of booting May 26 14:50:22 <_av500_> unless they need the jtag May 26 14:50:33 <_av500_> thats onboard on the BBW only indeed May 26 14:51:21 i have enabled the uart2 by inserting "uart2: serial@4802200 { status = "okay" };" into the file am335x-bone-common.dtsi. do i have to do some other muxing? May 26 14:52:30 <_av500_> timm: there are a few posts on that on the mailing list May 26 14:53:59 <_av500_> http://www.berriman.co.uk/beaglebone-black-with-rs232-cape/ May 26 14:57:45 PaulePanter: your chances are probably better in engaging with the local hacker-spaces and hacker communities May 26 14:58:19 <_av500_> as in somebody at c-base May 26 14:58:23 <_av500_> they have an irc channel May 26 14:58:41 I think there's more than just c-base May 26 14:58:52 in-berlin and others come to mind May 26 14:59:17 <_av500_> maybe May 26 14:59:40 _av500_: thanks May 26 15:01:23 _av500_ : so May 26 15:01:32 _av500_ : the work being done is to implement a new bootlodaer May 26 15:01:33 loader May 26 15:01:46 ??? May 26 15:02:09 _av500_ : are you absolutely sure that the soc on the black is not at all different from the soc on the original as far as register init by the bootloader goes? May 26 15:03:57 CareBear\, there are these things called TRMs....they tell you things like this.... May 26 15:05:02 MLO has been pretty similar for all OMAP3/4 and AM3xx I've seen so far, but then I never looked very closely let alone at the source code May 26 15:29:06 _av500_: for your next caturday - http://imgur.com/ZPMfKhC - you're welcome May 26 15:29:50 dm8tbr, thats just.....wierd May 26 15:33:36 the kickstarter vid is even more wierd May 26 15:34:29 if i had a bike, i would buy one May 26 15:37:10 KotH, you need a bike...good exercise. May 26 15:38:34 nah.. the place i live has no nice roads to ride a bike :-( May 26 15:38:53 and my way to work is infested with trucks May 26 15:39:46 * KotH spends his money rather on overly expensive quartz oscillators and chocolate May 26 15:40:49 <_av500_> CareBear\: same SoC May 26 15:43:52 pfew, that's one expensive device :/ May 26 15:44:29 produced in usa May 26 15:45:01 * KotH wonders why that even counts as an quality argument May 26 15:45:31 "Schlechtes muss nicht billig sein" (unrelated to the kickstarter project though) May 26 15:45:40 * KotH nods May 26 15:46:05 the last item i bought that was advertised as "made in usa" was broken by design.. and did cost me 500eur May 26 15:48:48 not everything from here is broken by design. May 26 15:50:06 * ka6sox refrains from commenting about things that are broken... May 26 15:51:55 yeah May 26 16:21:43 Anybody have any problems with the BBB crashing under load? May 26 16:23:34 Haven't done any load tests personally, but it's a good thing to test. What's your load? May 26 16:25:31 Not very much. May 26 16:25:59 If I'm transferring something via SSH from the local network and it's clipping along at 5-6MB/sec it will inevitably crash. May 26 16:26:39 I'm running it on USB power, but the supply is 5v @ 2A. May 26 16:27:14 Interesting. May 26 16:27:16 And if I boot it up with the Ethernet plugged in it will crash as well... May 26 16:27:33 Just starts to boot and then completely shuts off. May 26 16:28:04 Just wondering if I got a flaky board or not. May 26 16:28:38 I have an original BB and haven't ever had any issues like this. May 26 16:28:54 That looks bad. My BBB always has the Ethernet cable inserted, and it's certainly never crashed on bootup. In fact it's never crashed at all, and I do install packages which load up the network. May 26 16:29:55 Anything in the log? May 26 16:30:20 Nothing that seems to be tied to anything in software. May 26 16:30:33 I think I may order another one and try to RMA this one. May 26 16:31:04 Is anything on your board hot, the PHY chip in particular? May 26 16:31:10 The fact that it wouldn't boot with Ethernet plugged made me the most suspicious of a hardware problem. May 26 16:32:06 I haven't checked, I'll try again. May 26 16:33:03 windexh8er: this might still be related to the way how you power it. It probably senses the USB port and tries to limit to 500mA May 26 16:33:19 * dm8tbr would recommend to power from the barrel connector May 26 16:33:21 I've tried a few different distributions and they all do the same thing. May 26 16:33:43 So even when it's powered via a wallwart directly to mains it will drop to the 500mA? May 26 16:35:26 If it won't boot with Ethernet plugged in, that would seem to eliminate bad memory as the cause, since boot-time and post-boot memory use is likely to be different. Does suggest it's Ethernet hardware, although not really much data. May 26 16:38:40 Well, boot time is pretty power-intensive, so maybe it's a power issue. Monitor the power during bootup with a DVM or scope? The transients are smoothed out so you have a good chance of spotting a bad voltage dip just by eyeballing. May 26 16:40:18 It was easy to spot power problems during bootup on Pi with its seat-of-pants power implementation. :P May 26 16:41:20 Are there any pins I can measure across to see the amperage being pulled? May 26 16:41:40 Hi I have two beaglebone black boards, just run through the opkg update and upgrade, now both of them appear to not be responding...help May 26 16:42:03 All the LEDs are on solid, no flashing May 26 16:42:34 They don't appear in my router May 26 16:43:00 windexh8er: not looked, because never had any power problems on BB white nor Black. Test points is a good question though. I'd look in the schematic. May 26 16:43:42 windexh8er: the SRM might know if there is a shunt and how to interface / read it May 26 16:44:14 the easiest test would be to just take a 5V psu with barrel-connector and power it that way May 26 16:44:54 Sy_: Unfortunately, that is the single most common problem reported. Really CircuitCo should temporarily remove the recommendations to upgrade until it's resolved. It's failing for too many people. May 26 16:45:24 dam....can I do anything to recover them? May 26 16:45:54 windexh8er: My board exhibits exactly the same problems when powered by USB May 26 16:46:08 I think there is a simple recovery procedure with booting from microSD May 26 16:46:16 Sy_: The recommendation I've seen given here most frequently is: Make yourself a bootable SD from a standard image, boot that, and use it to diagnose your messed up eMMC. May 26 16:46:25 Its absolutely fine powered using the barrel plug thing May 26 16:47:05 Bugger...don't have an external PSU yet....or SD with boot image, on order. May 26 16:47:11 DigiDaz_: excellent, two identical behaviors is very good datapoint. Thanks. May 26 16:47:16 DigiDaz_: Interesting! May 26 16:47:54 Was trying to get mySQL server installed and running, but there were problems there to. May 26 16:48:07 Baby steps :P May 26 16:48:39 Sy_: You can write out one of the emmc restore images which will recover the emmc back to stock. May 26 16:48:44 I have it on the floor running as a PBX at the moment but until I powered using the barrel plug, I couldn't even copy an image to eMMC from an SD card without it crashing, not could I boot with ethernet plugged in. I tried multiple USB poers supplies too May 26 16:48:55 Hi all. I've got a BeagleBone (white) with an Edimax EW-7711USn WiFi adapter and a Huawei E160 3G modem plugged in to a non-powered USB hub. It's been working fine for >a month, but today it's started acting very eratic. Am I possibly drawing too much current? May 26 16:49:20 Sorry for my ignorance, how? May 26 16:49:24 DigiDaz_: That's exactly the same problem I was having. Annoying as heck - considering my original BB never exhibited the same behavior. May 26 16:49:53 Its been up 3 days 18 hours now the the barrel plug thingy May 26 16:49:57 Sy_: You can just snag the eMMC flasher image from here: http://beagleboard.org/latest-images May 26 16:50:02 powering over USB is always a challenge May 26 16:50:07 Sy_: Second link down. May 26 16:50:14 as you have a hard 2.5W power envelope you have to stay in May 26 16:50:20 if you exceed that - boom May 26 16:50:41 dm8tbr: Ahhh... Was that not the case in the original BB? May 26 16:50:41 Downloading now. May 26 16:51:09 windexh8er: I don't remember right now, it might have not limited the current to 500mA. May 26 16:51:26 it certainly booted in a low power mode though May 26 16:51:27 I've given up trying to get any sort of HDMI output too :) May 26 16:52:28 Are they're any good FAQ's around for getting mySQL running on the board? May 26 16:52:31 dm8tbr: Agreed. The BBB out-of-the-box experience is really terrific, so easy for beginners within minutes. But the first recommendation should be "Get 5V barrel connector PSU before substantive upgrades." May 26 16:52:57 Sy_: So once you have that down you can write it out to an image directly by using xz: `xz -cd ./BBB-eMMC-flasher-2013.05.20.img.xz > /dev/mmcblk0` May 26 16:53:17 If you're on Linux or OS X (although you need the xz package on OS X). May 26 16:53:24 Sy_: What distro you got running on it? I have MySQL running under Debian no problem May 26 16:54:00 Another question then; I'd like to use a powered USB hub - are there adapters that have a two plugs on the end, one for the Bone, and one for the Hub? May 26 16:54:04 I am using the Angstrom Linux as it came.... May 26 16:54:08 (to avoid having to plug in two plugs May 26 16:54:11 I'm running on Windows 7 64 May 26 16:54:18 Do any of you guys have any recommendations for the PSU, I'm just using an IP phone one at the moment May 26 16:54:28 Sy_: http://www.armhf.com/index.php/boards/beaglebone-black/ May 26 16:54:47 Sy_: There some nice images there if you're interested in running Debian / Ubuntu for BBB. May 26 16:54:50 narcos: I've seen such, but make sure to get a power supply that can handle the total current drain May 26 16:54:58 Sy_: There's also some good info on how to flash to eMMC. May 26 16:55:12 ty, will take a look May 26 16:55:28 dm8tbr: Got any links? I can't seem to find on Google - suspect I may be searching for the wrong terms. May 26 16:55:29 DigiDaz_: Is there barrel plug 2.1mm? May 26 16:55:38 DigiDaz_: suitable ones are listed as standard BBB accessories almost everywhere. If you use Farnell in any country, it's on same page as BBB. May 26 16:55:41 DigiDaz_: there/the May 26 16:56:01 K, thanks, it was farnell I got it from May 26 16:56:21 Do you think mayber the PSU could make HDMI an issue? May 26 16:56:23 narcos: I've seen it with adafruit IIRC May 26 16:56:54 I now have the BB-eMMC-flasher-2013.05.20.img.xz file, what do I do with it ? May 26 16:57:06 dm8tbr: Ok I'll pull that into my Google query May 26 16:57:32 Sy_: Just put it on an SD and then reboot May 26 16:57:40 Don't know about HDMI power requirements, but given the high HDMI data rate, it's unlikely to be very frugal. May 26 16:58:06 It will chug and whir for about half an hour or so, then it will be installed on the eMMC May 26 16:58:13 from Windows 7 host? May 26 16:58:39 Sy_: Yep, but do you not want a Debian or Ubuntu instead? May 26 16:58:56 Sy_: beagleboard.org/Getting Started#update May 26 16:59:07 Sy_: You can follow that for Windows. May 26 16:59:20 Sy_: You can't just copy it to the mSD card, you need to write it out. May 26 16:59:38 narcos: ignore the picture ● Anleitung zur Auflistung der Informationen zur Fehlerbehebung May 26 16:59:42 (folge dieser Anleitung Schritt-für-Schritt und lasse dabei *keinen* der 5 (fünf) Punkte aus!) ➜ http://justpaste.it/Infos-zur-Fehlerbebung May 26 16:59:45 gargh May 26 16:59:47 sorry May 26 16:59:48 https://plus.google.com/u/0/100242854243155306943/posts/NqjuXowttVd May 26 16:59:53 wrong paste buffer :-/ May 26 16:59:58 I tried to go down this road earlier today, but there doesn't seem to be a flash tool available for Windows 7 64bit. May 26 17:00:08 Sy: Sure there is. May 26 17:00:11 Image Writer I mean May 26 17:00:27 Sy_: It's listed in the documentation - there's an Ubuntu image writer you can use under Windows. May 26 17:00:31 dm8tbr: Heh, np. Great - thanks for that! May 26 17:00:40 mmm....found it May 26 17:00:43 sorry May 26 17:00:55 I'm using windows 7 64bit May 26 17:01:48 win32diskimager seems to work for every image I've tried so far May 26 17:03:24 DigiDaz_: http://www.adafruit.com/products/276 < Seems like a decent PSU. 5V @ 2A for $10/USD. May 26 17:03:42 DigiDaz_: Unfortunately out of stock right now. May 26 17:04:02 I recommend the nexus 7 power supply. May 26 17:04:05 I'm UK but I'll take a look, thanks, I'll see if I can get the same here. May 26 17:04:35 Downloading debian image now May 26 17:05:02 windexh8er: buying a random powered hub usually includes a 2-3A 5V supply at about the same price May 26 17:05:06 SpeedEvil: That'd be USB though. May 26 17:05:18 This thing is making a great little PBX at the moment but I want to use it ideally as a thin client May 26 17:05:22 dm8tbr: Ahhhh, good point.

May 26 17:06:24 yes May 26 17:06:29 Gotcha. May 26 17:06:36 That might be the best path. May 26 17:06:36 So why have these units become unaddressable? May 26 17:06:39 I'd actually probably glue the 2.1 plug in May 26 17:06:44 Since I have tons of 2A USB plugs. May 26 17:07:00 As chances of losing a random 5V PSU are high May 26 17:07:22 dm8tbr: So, if the Bone likes 1A, and the USB powered hub likes 2A, I'd need a 5V 3A adapter? (I'm not sure if we just stack the amps ?) May 26 17:07:49 narcos: well it's an up-to-thing May 26 17:08:05 depends on what you want to use with the hub May 26 17:08:51 dm8tbr: I've got a BeagleBone (white). I want to plug in an Edimax EW-7711USn WiFi adapter, and a Huawei E160 3G modem May 26 17:09:52 dm8tbr: I've got a 5V 2A adapter powering it at the moment May 26 17:10:13 mh, might be enough, or not May 26 17:10:45 does the adapter get very warm? May 26 17:11:01 No, it doesn't feel warm May 26 17:11:26 It's odd though - the bone was working fine with these two devices for a month, and today it's behaving all eratic May 26 17:11:42 could be the psu dying though May 26 17:11:51 e.g. can't detect one of the devices, or the 3G modem claims to be connected, but isn't May 26 17:12:04 ahhh May 26 17:12:09 probably something psuchedelic May 26 17:12:33 PsychedelicSupplyUnit May 26 17:12:51 Ohhh May 26 17:13:57 I'll try buy a new one tomorrow. May 26 17:18:00 Is the problem I've encountered limited to the Angstrom Linux ? May 26 17:19:03 What is the milliamp limit for the USB port ? May 26 17:19:25 It's complex. May 26 17:19:26 I can't seem to see it referenced in the docs, and Google gives me figures from 100mA to 500mA May 26 17:19:35 What are you trying to do? May 26 17:20:10 Compliant devices will only draw 100mA without negotiating with the host, and then only up to 500mA thereafter. May 26 17:20:22 SpeedEvil: Want to plug in an Edimax EW-7711USn WiFi adapter, and a Huawei E160 3G modem May 26 17:20:29 Devices connected to chargers can draw more May 26 17:20:42 SpeedEvil: usb3 allows to draw more May 26 17:20:47 Quite May 26 17:21:34 Am I correct in thinking that I need to find how much current these devices each want, and sum that value up? May 26 17:21:43 ( my university physics is flakey ) May 26 17:21:54 narcos: uhmm.. 3G modesm are known to draw several A peak May 26 17:22:16 narcos: peak as in "over several seconds until it can connect" May 26 17:22:29 KotH: Ah ok May 26 17:23:49 Any advice on how I should proceed? May 26 17:23:54 narcos: anything below a good 5V 4A supply wont do it May 26 17:24:01 go for a 5A supply if you can May 26 17:24:18 and add some big caps to buffer for the load changes May 26 17:24:44 KotH: OK - I'll buy a 5A one tomorrow. And this may negate the need for a powered hub? May 26 17:25:06 i dont see where the hub comes into play May 26 17:25:48 KotH: Perhaps I misunderstood. I thought that if my USB peripherals were drawing more current than the USB ports could supply, I'd need to use a powered hub May 26 17:25:58 ah.. May 26 17:26:05 they are definitly drawing more May 26 17:26:13 you have to supply them somehow May 26 17:26:37 i dont know whether a powered hub helps (these tend to have current limiters sometimes) May 26 17:26:59 you have to try May 26 17:27:15 but with a 2A supply it's definitly a power problem May 26 17:27:27 you probably used the psu at its limit for too long, wearing out its parts May 26 17:27:57 KotH: So, having a greater PSU will enable the Bone to supply greater power to USB peripherals? Is there a limit on this? I'm not sure I understand the electronics properly - but does the USB port have a limit of how much power it can supply, independent of the PSU? May 26 17:28:46 uhmm.. i dont know the schematics of the bone, but if it doesnt have a current limiter somewhere, it can supply more power, yes May 26 17:28:52 KotH: Ah ok - that's good to hear (that the PSU may be my problem). The board actually came with a 1A, and I went and found a 2A, thinking that'd be plenty. May 26 17:29:49 not for 3G May 26 17:29:53 Not having much luck with my card reader is there any other known way to recover these without re-doing the image? May 26 17:30:01 narcos: well.. a standard wifi module can use 2A peak, i've seen gsm/3g modem with 4A peak May 26 17:30:52 KotH: Ouch. How do you measure that? May 26 17:30:53 Fortunately found another card reader that does work May 26 17:31:03 narcos: i've read the specs May 26 17:31:29 Writing image to SD card now... May 26 17:31:45 KotH: OK - I've been trying to find specs, but haven't seen such references yet May 26 17:32:10 narcos: they are not easy to find for consumer devices May 26 17:32:38 narcos: easiest is to find out what chipset they use, and then look up the specs of the chips... you can find them May 26 17:32:45 KotH: ahhhh ok May 26 17:32:51 * narcos tries that May 26 17:33:26 have to go, thank you for your help. May 26 17:33:48 Seems to be a Ralink RT2870 chipset for the WiFi May 26 17:33:48 narcos: er... *if* you can find them May 26 17:33:54 * KotH should not type while cooking May 26 17:34:09 heh May 26 17:34:47 I know of some of these GPRS issues but I never experianced them with usb based modems. anything about 1 am will certainly stop a normal pc from working May 26 17:35:16 not really May 26 17:35:28 the usb 5v is directly connected to the psu May 26 17:35:30 just a quick question to make sure I'm not entirely misled: The default angstrom linux of the BBB does not make use of the HDMI output, right? So I can use the GPIO pins associated with HDMI without running into conflicts and having to unload some driver? May 26 17:35:36 most pcs dont even have current limiters May 26 17:35:43 (lsmod did not show any HDMI related module, that's why I ask) May 26 17:35:48 so, you can draw anything the psu can deliver May 26 17:36:32 shorting a usb power gives you quite a nice spark...and your pc might not boot anymore afterwards May 26 17:52:03 Jazzdude: HDMI is used by default May 26 17:52:11 like one would expect May 26 17:53:21 koen, ok, then how can I turn it off to free the pins? May 26 17:53:40 lsmod didn't list any driver that I could just unload May 26 17:54:04 what makes you think 'rmmod' would free up the pins? May 26 17:54:12 hint: it wouldn't May 26 17:54:37 I just read the introduction document and it suggested that unloading the driver would do that May 26 17:55:05 Quote: "However, note that the Linux software typically allocates these for use by the HDMI driver, so your software might not be able to get access to them without unloading that driver." May 26 17:59:08 koen, so what do you suggest I do in order to use these pins for other tasks? May 26 18:00:00 KotH: according to USB specification (and device is required to meet that specification in order to be certified), shorting of any USB pins should not be damaging to the device May 26 18:04:44 jacekowski: and how many devices do actually get fully certified? May 26 18:04:54 jacekowski: or how closely are those specs followed? May 26 18:05:22 Hi everyone, are there any drivers needed to setup the usb network with the BB-Black on the PC side? I am using Gentoo and I fail to access the 192.168.7.2 default address. help will be much appreciated! May 26 18:05:52 Guser: usb network? why dont you just use ethernet? May 26 18:06:25 It doesn't have a default network address via ethernet and I cannot connect it to a screen at the moment May 26 18:06:57 Guser: serial console is your friend May 26 18:07:09 KotH: great idea! thanks May 26 18:08:09 KotH: but just in case, do you know of any drivers the USB network requires? Do I need to setup a tun device? May 26 18:08:25 * KotH knows nothing about that May 26 18:08:36 * Guser nods May 26 18:08:54 * KotH is just a lowly, uneducated troll May 26 18:09:27 i finally made my BBB to talk to my LCD7 :) May 26 18:09:27 * Guser hugs KotH and goes to set up the serial console May 26 18:10:22 not sure weather HDMI is broken now or not May 26 18:11:06 KotH: oh don't be sure hard on yourself :P May 26 18:11:43 mranostay: at least i know the difference between good chocolate and beer ;) May 26 18:12:25 why not zoidberg^H^H^H^H in one May 26 18:12:34 *both May 26 18:12:42 ugh.. May 26 18:12:53 that would be a waste of good chocolate May 26 18:13:04 actually, that would be a waste of any chocolate, good and bad May 26 18:13:16 boo May 26 18:13:22 :) May 26 18:13:43 i cut the line here --> http://rogue.com/beers/voodoo-bacon-maple.php May 26 18:15:15 * KotH draws the line here -> http://www.independent.co.uk/news/world/asia/a-threat-to-cocacola-japan-sips-the-eel-thing-879422.html May 26 18:25:21 eel soda May 26 18:25:28 why? comes to mind May 26 18:26:36 because japan May 26 18:26:40 because they can May 26 18:26:49 I am brand new to beagleboard and want to run my first program on cloud9. I am a java programmerb ,ut cannot get a simple javaScript to run. May 26 18:27:01 mranostay: ever been there? May 26 18:27:39 nope May 26 18:27:46 big mistake! May 26 18:29:26 to restore your faith in the stupidity of humankind: read yahoo answers for a couple of minutes May 26 18:30:55 KotH: i've had sony laptop that followed those specs properly May 26 18:31:07 KotH: and that laptop even had proper current limiting May 26 18:31:20 lucky you May 26 18:31:22 KotH: when current on port exceeded negotiated value it would turn off that port May 26 18:31:32 unlucky you May 26 18:31:36 laptops often have polyfuses and stuff May 26 18:31:52 that part caused me some issues with HDDs and stuff May 26 18:32:20 but i could just short out usb port on it and all i would get is warning message saying that overcurrent was detected May 26 18:43:14 windexh8er i know its a bit late . . . waas just reading up though, i think i recall someone on the groups saying a new USB cable fixed that for them May 26 18:43:59 power issues over USB that is May 26 18:44:45 m_billybob: Thanks. Ordered a few 2.1mm barrel PSUs and a few USB to 2.1mm as well. May 26 18:45:12 hopefully it fixes your problem if that doesnt work, yeah RMA that sucker May 26 18:45:25 Im powered via USB but i also have usb 3.0 on that port so . . . May 26 18:45:41 Does Ninja blocks force the user to plug in via a barrel connector then? Guessing so since they power both BB and Arduino in one unit. May 26 18:45:59 * m_billybob doesnt know May 26 18:46:48 m_billybob: I'm guessing it will. Seems like the USB is limited significantly. Wish they would send the BB with both a mUSB as well as USB->2.1mm May 26 18:47:20 Most people have a >1A USB power plug laying around at least. :) May 26 18:47:37 well i dont recall the exact specs the SRM says, but at boot the bbb can draw up to 460mA I think, and if the USB supply you';re using a a tiny bit flaky . . . yeah i could see that being an issue May 26 18:48:21 you're sure the USB hub you're using will supply up to 2A over one port though ? May 26 18:48:27 m_billybob: Well it's odd because I've tried numerous >2A USB plugs and none of them seem to be able to provide the power at boot, especially if Ethernet is plugged in. May 26 18:48:46 yeah really odd May 26 18:48:49 Yeah, it's direct. USB wall plug (2A) directly to BBB. May 26 18:48:58 ah gotcha May 26 18:49:06 i assumed a hub, bad me May 26 18:49:08 Someone else said they had the exact problem - something my original BB didn't seem to have a problem with. May 26 18:49:12 No problem. May 26 18:49:20 Thanks for the feedback. :) May 26 18:49:47 troublelshooter at heart uf u dotn know ill still bug yeah in hopes i can figure it out lol May 26 18:49:54 if i* May 26 18:50:36 but yes, thats really strange maybe the USB portion of the board is . . .bad or flaky May 26 18:52:46 m_billybob: I'm going to order another to validate - if the second one does the same thing I'll chalk it up to the design, otherwise I'll RMA. Either way I'll end up with two BBB. Not a bad thing. :) May 26 18:53:04 yeah, debian runs :)) May 26 18:54:07 Defiant: Robert Nelson does an awesome job of packaging up Debian/Ubuntu. :) May 26 18:54:38 windexh8er: whats packaged? May 26 18:55:50 Defiant: Robert Nelson does most of those builds if you downloaded an image of Debian. And then John Clark did a bunch of changes for writing them directly to the BBB eMMC. May 26 18:55:56 windexh8er, yeah he does i followed his instructions little over a week ago when we got our two blacks, and been running debian ever since lol May 26 18:56:12 * m_billybob isnt lookign back either May 26 18:56:47 m_billybob: Wheezy for sheezy? May 26 18:56:52 windexh8er: I think I read about it in the wiki, but could not follow it - it was too complicated for me :( May 26 18:56:56 lol Wheezy May 26 18:57:20 Defiant: It's pretty easy actually... Did you check out the builds on this page: http://www.armhf.com/index.php/boards/beaglebone-black/ ? May 26 18:57:30 Defiant: May 26 18:57:30 Defiant, its an exersize in copy paste, doesnt get much easier . . . May 26 18:58:05 Defiant: There's instructions as well... But any of the SD writing instructions work. You just boot from mSD and then write the image back over to the mmcblk1 device. May 26 18:59:43 windexh8er, never really though abotu that much myself becasue i want to boot sd for now, but yeah you could just go bac up to the top and copy the sd image ovr exactly like the instructions i bet May 26 19:00:02 to emmc i mean May 26 19:00:07 shouldnt be too much different May 26 19:00:32 Defiant: I modify the rootfs partition before booting off the image I just wrote to the mSD to include the .xz of the image I want to write back to the eMMC. May 26 19:00:59 m_billybob: Yep, exactly. May 26 19:01:29 windexh8er: ok havn't seen that prebuild image. Anyway I got the debian running by copying the kernel/loader from angstrom und doing a simple debootstrap May 26 19:01:32 m_billybob: The xz utility is already in the build, so you can write it back directly to eMMC. May 26 19:01:52 Defiant: Awesome. You did it the hard way first. :) May 26 19:02:16 Defiant: Everything else should be cake next time you build one. May 26 19:02:17 well even if not wouldnt be too hard to apt0get install May 26 19:02:30 apt-get install* May 26 19:02:37 windexh8er: Actually pretty easy..but this is not my first arm board ;) May 26 19:03:14 lol i got my cross dev system srtup May 26 19:03:15 Defiant: I just looked for someone who already did all the work. :) And, low and behold... May 26 19:03:21 setup* May 26 19:03:37 wonder how mnay people are doing this how im doing it May 26 19:06:00 hmm debootstrap May 26 19:43:17 Hello, having difficulty in reading any GPIO0 or GPIO2 pins on the Beaglebone Black. I can read GPIO1 just fine. The "cat $PINS" correctly shows my GPIO0_xx pin is set to 0x2f (i.e. mode 7, input) and am trying to read it via PRU-ICSS. In the assembler, I have set the GPIO_OE register, and when I read GPIO_DATAIN, I just see 0x00000000 :-( And yet it works fine with GPIO1. Any ideas? May 26 19:44:53 I've been documenting it at this URL http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/05/22/bbb--working-with-the-pru-icssprussv2 to help others use the PRU-ICSS too. However, the GPIO0 and GPIO2 reads have got me stumped May 26 19:46:15 Hi, does somebody have time to give me advice on a project with the beaglebone? May 26 19:46:53 maybe May 26 19:46:59 what are you up to old pal? May 26 19:47:12 Is there a way to get audio in on the beaglebone May 26 19:47:33 using the audio cape May 26 19:47:41 ? May 26 19:47:48 yes May 26 19:47:51 audio cape May 26 19:47:54 What is that? May 26 19:48:00 look it up bro May 26 19:48:04 I do not own a beaglebone yet ;) May 26 19:48:11 ask the internet search engine of your least distrust May 26 19:48:18 bing it lmao May 26 19:48:36 that will work May 26 19:48:52 Oke thanks. May 26 19:49:19 shabaz, that looks great and exactly like what I'll have to look into too. I'm afraid I can't help you with your problem, but thank you so much for sharing this! May 26 19:49:42 first reasult on bing May 26 19:49:43 http://images.wookmark.com/175333_headphones-white-animals-dogs-phones-1920x1080-wallpaper_wallpaperbeautiful_77.jpg May 26 19:49:44 lol May 26 19:50:04 lol May 26 19:50:22 Thanks for your help May 26 19:50:22 ah, no problem at all! The more eyes look at it, the more chance we can figure it all out! 4000 page tech ref manual is a bit of an achievement by TI.. I've looked at 1% of it May 26 19:52:35 shabaz, where do the troublesome GPIO pins sit on the header? Sorry if this is a naive question, I'm very new to this May 26 19:54:15 Anyone recommend a GSM cape for the Bone? May 26 19:57:32 Hi Jazzdude, I've been using header P8 on the BBB, it has about 12 pins free for use, of which some are GPIO1, some are GPIO2 and some GPIO0. The GPIO1 works well for me currently. Just the others which I cannot seem to read at all. May 26 19:58:14 shabaz, does their use maybe interfere with onboard devices? May 26 19:58:39 maybe some driver has allocated them and prohibits you from reading it May 26 20:01:00 Possibly, but I tried to pick ones that looked like they were not used according to the schematic. For example, GPIO0_27 appears unused, so I thought I could use that. I could correctly set it to mode 0x2f (which means Mode 7 GPIO input) but reading the DATAIN register just shows zero for all GPIO0 pins. I suspect some driver as you say, or alternatively maybe GPIO0 and GPIO2 need to be 'enabled' May 26 20:01:01 somehow, but I've no idea how. May 26 20:03:52 I would be very interested in a solution too May 26 20:04:16 have you tried to use them as an output too? May 26 20:05:32 good point. yes for GPIO1 (and it worked), but not tried for GPIO0/2. I'll try that and give you an update. May 26 20:06:37 BEER! May 26 20:06:48 KotH: not chocolate beer you can relax May 26 20:07:22 hi florian May 26 20:08:08 re May 26 20:20:24 What is the current kernel tree? Is it https://github.com/beagleboard/kernel/tree/3.8? May 26 20:25:10 Hi Jazzdude, seems I can't use GPIO0/2 as output either. I tried GPIO0_27. I set it in device tree to 0x07 (i.e. Mode 7 GPIO output), and then in the PRU-ICSS I cleared the GPIO_OE bit (which enables output), and then wrote to GPIO_SETDATAOUT but the voltage on the pin (header P8, pin 17) was at 0V. May 26 20:29:10 shabaz, you are reading r30 correct bits? May 26 20:30:41 also these are th pins that are hooked up: http://elinux.org/Ti_AM33XX_PRUSSv2#Beaglebone_PRU_connections_and_modes May 26 20:31:30 Hello, I was using GPIO mode (mode 7) instead of the PRU GPO/GPI mode (mode 5), because mode7 will still allow me to get to about 25MHz pin speed, and there are not enough pins in mode 5 (i.e. usable by R30/R31) on the headers. Header P8 only has a few for example. So I thought I'd use GPIO mode instead, because that gives me several GPIO0, GPIO1 and GPIO2 pins. The reading/writing of GPIO1 May 26 20:31:31 works well from the PRU. May 26 20:31:54 okay so you are needing more pins... May 26 20:32:06 I don't remember what is on the 0_2 pin normally May 26 20:32:37 The example pin I've been using so far is GPIO0_27, which is P8 pin 17 May 26 20:33:14 However when I read the DATAIN, the entire register is 0x00000000 May 26 20:33:50 there is a Gotcha on that page related to GPIO0_27 May 26 20:34:00 the elinux.org page I pasted has the caveats May 26 20:34:01 oh.. let me check. May 26 20:34:43 side note: NEON rocks. May 26 20:34:58 sorry its 0_7 not 0_27 May 26 20:35:05 sorry...I got them confused. May 26 20:35:08 ah, np May 26 20:35:30 what is the Beagle Pin name for P8_17...let me look @ pinmux.tking.org May 26 20:35:59 is this a BBB? May 26 20:36:04 Should be CONF_GPMC_AD11 if I've got it right May 26 20:36:16 (which is 0x2c in the pinmux) May 26 20:36:22 its bbb name is spi0_cs0 May 26 20:37:11 whoops May 26 20:37:14 wrong connector May 26 20:37:19 okay I see what you mean May 26 20:37:30 what mux settings are you using? May 26 20:37:51 I'm using <0x2c 0x2f> May 26 20:38:22 do you have a pullup or pulldown? May 26 20:38:48 (0x2f should be mode 7, with no pullup/pulldown, I'm using a 2.2k resistor and manually connecting it to 0V or 3.3V) May 26 20:39:14 0x02C 0x27 May 26 20:39:33 0x2C 0x07 May 26 20:39:48 dunno where you got F from May 26 20:39:50 right.. think 0x27 is Mode 7 input, with pulldown, and 0x07 is output May 26 20:40:08 0 is input May 26 20:40:12 27 is output May 26 20:41:11 so I dunno where you got the f May 26 20:42:11 so you have a pullup enabled and its set for output May 26 20:42:12 0x2f should make the pin an input, according to this: #define IEN (1 << 5), i.e. 0x20 and #define OFF (1 << 3) which is 0x08 and the mode 7 being 0x07, so this all adds up to 0x2f May 26 20:42:37 maybe I got my bits reversed..let me look at the code May 26 20:47:40 shabaz, I think you found a bug...let me do some checking and get back to you ;) May 26 20:48:26 thank you ka6sox! May 26 20:51:17 ya, I see he got the receiver enabled/disabled backwards in the JS May 26 20:51:34 its very confusing...I had to read it 3X :0 May 26 20:52:07 * mranostay blames javascript May 26 20:52:17 +1 May 26 20:52:39 mranostay, I blame lousy inconsistent register values :P May 26 20:52:57 one way disables with a 0 and the other way disables with a 2 May 26 20:52:59 er 1 May 26 20:54:53 shabaz, okay I have what you have now...thanks for finding this bug. May 26 20:55:23 ah, np. so it's an issue with the pinmux software? May 26 20:55:38 I either told him wrong or he got it confused. May 26 20:56:31 because this is confusing...I tried to make it better but apparently messed up :/ May 26 20:56:50 I found another error too that I have to fix on P9 May 26 20:57:27 P9_17 forgot a slot May 26 20:57:45 (mode) May 26 21:02:33 ka6sox, what is the easiest way to obtain updates and bugfixes like that as a user? May 26 21:03:34 I haven't made myself too familiar with angstrom yet (only got my BBB today), but is there an update mechanism like with debian? May 26 21:07:06 Hi Jazzdude, I think the process is to type opkg update and then opkg upgrade, but I've not done that yet May 26 21:08:14 Jazzdude, this is a web app that we are writing May 26 21:08:26 it still has a few bugs and we are fixing them. May 26 21:08:54 shabaz, don't do that please...that does not work. May 26 21:09:09 its currently broken. May 26 21:09:20 oh, ok May 26 21:09:21 and will force you to reflash. May 26 21:37:03 I've seen stuff suggesting that one of the spi ports is enabled in recent angstrom images... I just flashed the 5.20 image, and there's no /dev/spi* :( May 26 21:37:31 hm maybe the stuff I'm reading is bbw specific May 26 21:45:57 ka6sox: Interesting that using opkg will (temporarily) brick your BBB. There was a user in here earlier that had the same problem. May 26 21:46:15 ka6sox: Seems odd whoever controls that repo that they'd leave it in a state like that. May 26 21:46:52 ka6sox: Could be pretty frustrating for people just getting hardware and following instructions. :) May 26 21:49:55 * mranostay dances in May 26 21:50:23 is it bad i don't recall all the addresses i've off the top of my head? May 26 21:58:26 windexh8er, the word I will say is "in a state of flux" May 26 21:58:40 it takes a lot to maintain a distro. May 26 21:59:12 update/upgrade is a Ubuntuism that is being brought in. May 26 21:59:29 heh May 26 21:59:32 Ubuntu is a Binary Distribution... May 26 21:59:36 one does not simpley.. May 26 21:59:57 Angstrom is a Source Distribution (similar in many ways to Gentoo) May 26 22:00:02 mranostay, +1 May 26 22:00:21 flux capacitors? May 26 22:00:43 mru, it takes 1.21 Jigawatts to keep it going. May 26 22:01:13 ^Just to keep it going.... May 26 22:01:35 * mranostay loves the "are you a fugitive from law" checkboxes on an app May 26 22:02:25 I will say one thing for Javascript...errors show up quick and nasty. May 26 22:02:52 go go firebug May 26 22:03:10 mranostay: us customs have an app now? May 26 22:03:37 ka6sox: and inexplicably May 26 22:04:13 mru, no kidding May 26 22:05:19 mru: a permit for a item to be carried around May 26 22:06:14 mranostay, in plain sight or concealed? May 26 22:06:23 concealed May 26 22:06:41 uh oh May 26 22:07:16 who does open carry? May 26 22:07:20 I've never been able to keep the M4 out of sight... May 26 22:07:26 mranostay, they do in Arizona. May 26 22:07:36 well yes but AZ is a weird state :) May 26 22:07:53 any state i've lived in.. police would be called May 26 22:08:19 even Bama? May 26 22:08:30 probably in Mobile county May 26 22:08:35 open carry makes more sense to me May 26 22:08:38 I'm having a lot of problems with the BeagleBone Black, earlier today I updated the packages using opkg update and then after restarting it seemed to be bricked...I came into this chart earlier tonight and was advised to build an image on SD card then update, which I have done. I downloaded the Debian image, flashed to SD-Card, held in the boot button then connected USB, after a few initial flashes everything goes off and there are no l May 26 22:08:47 is there anyway back to a working board? May 26 22:08:49 Sy_, reflash May 26 22:09:01 get the flasher app and reflash it. May 26 22:09:05 How? I've tried this a few times May 26 22:09:25 1) plug it into REAL power..not USB May 26 22:09:33 heh May 26 22:09:41 I got the flasher, I think....ImageFlasher Win32DiskImager May 26 22:09:42 get a wall wart already May 26 22:09:53 I don't have a PSU for it. May 26 22:09:58 not what I'm talking about. May 26 22:10:09 there is a flashing app for the onboard. May 26 22:10:33 Where do I get that? I followed the link from the BeagleBone pages. May 26 22:10:38 you use the diskimager thing to create a sD card and the you plug it in. May 26 22:10:56 thats what I did May 26 22:11:13 1st thing, get a wall wart. May 26 22:11:19 onboard storage is a bad idea May 26 22:11:43 mru +1 May 26 22:11:46 we learned that with the classic 5 years ago May 26 22:12:00 apparently not May 26 22:12:15 xm has none May 26 22:12:20 I have two of these boards and both are now bricks....all I did was follow the instructions shipped with it. May 26 22:12:47 Sy_, I doubt they are bricks... May 26 22:13:09 Seems that way, no activity on either of them and I don't seem to be able to reflash them May 26 22:13:15 you can create a Angstrom image on a SD and boot it so its not a Brick. May 26 22:13:21 get a few more and build a house May 26 22:13:37 mru -1 May 26 22:13:54 Shouldn't the debian image work? May 26 22:14:00 Sy_, sunday afternoon isn't the greatest time... May 26 22:14:03 Sy_, YMMV May 26 22:14:15 YMMV ? May 26 22:14:30 I'm in the UK May 26 22:14:52 brilliant...so its almost midnight... May 26 22:15:04 Yep, just got back from a concert :) May 26 22:15:20 ELO tribute....left it flashing before I left, trying again now. May 26 22:15:32 okay "Your Mileage May Vary"...its from us colonials.... Means...I dunno... May 26 22:15:48 bugger May 26 22:16:04 Sy_: can you make a new SD card with the default image? May 26 22:16:18 can try May 26 22:16:55 http://downloads.angstrom-distribution.org/demo/beagleboard/ May 26 22:17:05 is that the latest still ^^^ May 26 22:17:37 Wanted to try an alternative to Angstrom as thats how I ended up here in the first place, after an update to the Angstrom packages. May 26 22:17:40 there is a later on koen's site May 26 22:18:00 *sigh* we need some "official" way to reset people back to stock. May 26 22:18:10 the flasher is that way. May 26 22:18:25 What's the link on that? May 26 22:18:32 I'll put it on elinux.. May 26 22:19:06 new policy, when someone asks a basic question that it's embarrassing that we don't have a good answer for, I'm putting it on eLinux. May 26 22:20:55 Seems others have experienced the exact same problem I have... May 26 22:21:09 http://beagleboard.org/project/angstrom/ May 26 22:21:26 alan_o, http://beagleboard.org/latest-images May 26 22:21:29 what is the meaning of life? May 26 22:21:33 42 May 26 22:21:36 the latest flasher image is 5_20 May 26 22:22:16 Sy_, what told you to do a opkg update; opkg upgrade? May 26 22:22:28 I want to kill that doco that is causing this issue. May 26 22:23:36 I always update something when I get it, because most of the time, things are shipped with older software and usually one or more patches are available. May 26 22:23:55 So you'd rather have new bugs than old bugs May 26 22:24:10 crap it is alan_o May 26 22:24:30 possibily, but hope that not everyone writes software like Microsoft May 26 22:24:31 Sy_, where did you learn those 2 commands? May 26 22:24:36 * alan_o takes a bow May 26 22:24:48 what 2 commands? May 26 22:24:58 opkg update; opkg upgrade? May 26 22:24:59 opkg upgrade ? May 26 22:25:02 yes May 26 22:25:27 one doesn't simply... May 26 22:25:55 mranostay, yes, we know...but if we are going to get to the bottom of this mess one must find out the source of the error. May 26 22:26:13 When I got the boards, I did a search on angstrom and tried to find out what was used to update it, I have used other versions of Linux, centos using yum, so I searched for the equiv. I also wanted to install mySQL as I need that.... May 26 22:26:29 but it wouldn't run, which lead me to update other things. May 26 22:27:16 okay I'm going to suggest that we add doco to the *official* site warning about doing what you did. May 26 22:28:05 ok, can see what your saying, but isn't it odd, to advise people that the hardware is ok, as long as you don't try to update the O/S ? May 26 22:28:25 I'm sure the hardware is still fine May 26 22:28:51 So far I haven't found a way back...I'm downloading the original image now. May 26 22:29:03 Source Based distributions sometimes have issues with "upgrading" from 1 version to another. May 26 22:29:26 opkg upgrade is something that has caused issues before... May 26 22:29:38 people assume this is like Ubuntu/fedora/etc... May 26 22:29:44 its not quite the same. May 26 22:30:01 ka6sox: and in fairness they have no reason to believe otherwise. May 26 22:30:44 ok, the next problem, assuming I can get it to work again, is that mySQL doesn't seem to work with Angstrom, there was another user on here earlier who said it works with Debain, but I can't get the board to flash from the SD debian image. May 26 22:31:33 Sy_: that's not a reason to just go changing distros. May 26 22:31:34 alan_o, I am not arguing this...I'd almost go in and send in a patch to make that option inert for now. May 26 22:32:18 ka6sox: I know. It's a problem. We need a bugtracker. May 26 22:32:33 alan_o, yes, we do. May 26 22:32:55 can I unload a .dtbo from capemanager through as sysfs operation? May 26 22:32:56 it doesn't help also that people want 47 different flavours of Distros to all work *now* on a 4 week old board. May 26 22:33:42 mhaberler: I'm glad you ask: http://elinux.org/BeagleBone#Device_Tree May 26 22:33:54 Sorry, don't buy that if the board isn't ready then it should be on release. May 26 22:34:10 alan_o, thanks! I was going to do that if you didn't May 26 22:34:17 we need to demystify DT May 26 22:34:22 how is the alan_o doing? May 26 22:34:51 mranostay: doing ok, been pretty busy... oh, I just remembered, you got a new job, congrats May 26 22:34:54 relocation? May 26 22:35:36 ka6sox: it's just a first pass. I'm sure it can be improved. May 26 22:36:07 I'll pitch in where I can if thats okay...this is becoming a stumbling block. May 26 22:36:12 alan_o: yeah i'm in Portlandia now May 26 22:36:22 alan_o: this refers me to http://elinux.org/Capemgr which shows how to compile and load a dts/.dtbo fragment; it has no hints as to unloading, which is what I was looking for May 26 22:36:49 oh.. unloading. hmm. I should read closer May 26 22:38:41 ka6sox: what's "flasher" about the emmc-flasher image? May 26 22:39:50 If I get it working on the Angstrom image again, should it then flash correctly to Debian ? May 26 22:40:11 Sy_: not sure what that means. May 26 22:41:10 I mean if I get the board functional again with the original image, can I then move onto Debian, which at the moment doesn't work May 26 22:41:38 you can try. Support may be limited. May 26 22:42:04 from reading drivers/misc/cape/beaglebone/capemgr.c I infer a leading '-' before the cape name (dts basename) unloads the slot May 26 22:42:21 I have an application where I need to get mySQL working, if it doesn't work with Angstrom then I need to change O/S May 26 22:43:23 Sy_: you should stop using phrasing like "it doesn't work with Angstrom" May 26 22:43:34 alan_o, +1 May 26 22:43:42 Sy_: no doubt, mysql can be made to work on any reasonable distro May 26 22:44:26 Why? How would you Phrase it when something doesn't start without a lot of additional help by hand? May 26 22:44:33 Sy_: if it's not packaged, it may mean building from source. May 26 22:45:04 It is packaged, I installled it using opkg install mysql5 May 26 22:45:19 ok, so what happened? May 26 22:45:38 It looked like it had installed, but after checking the service wouldn't start May 26 22:45:56 I then found a sight which looked like it would solve the problem, sadly it didn't May 26 22:46:05 alan_o, we need to explain how the DTS compiler works and how to create a fragment that can be loaded via capemanager. May 26 22:46:33 ok, so "the service wouldn't start" should be replaced with something like, "when I tried to start the service, I got an error message that said XYZ" or " when I tried to start the service, it looked fine but ps ax said mysqld wasn't running" May 26 22:47:41 try to be as descriptive as possible when reporting errors. Generalities like "doesn't work," or "thought I fixed the problem, but couldn't" don't enable anyone to help you with your problem. May 26 22:47:46 Sorry, I don't have a photographic memory, but I agree with what you are saying. May 26 22:48:05 I'm a software engineer so I agree completely. May 26 22:48:12 echo -BB-BONE-PRU-01 >/sys/devices/bone_capemgr.9/slots does cause a dmesg entry [35636.268412] bone-capemgr bone_capemgr.9: Removed slot #0 May 26 22:48:15 Hi ka6sox, I've written a short guide on that here, if you wish to append to it, or provide any link May 26 22:48:19 http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/05/22/bbb--working-with-the-pru-icssprussv2 May 26 22:48:20 How long should the boot button be held in for when restarting the system? May 26 22:48:32 ok great, so right now you're trying to get back to a bootable system where you can try it again, and give a more descriptive error report. Fair enough. May 26 22:49:15 ka6sox: yeah, that part I don't actually know, because mine builds as part of the kernel (and I just haven't done the compiler on the bone yet, too lazy to update my image, etc). May 26 22:49:42 shabaz: thanks, that looks very useful May 26 22:49:55 you're welcome May 26 22:50:25 shabaz, I'd really love to have everything in 1 place...we have a page on elinux.org for the PRU and that article would be awesome on a page there. May 26 22:50:28 Still waiting for the original image download to complete...slow broadband here...have tried to flash debian whilst waiting, after a few flashes of the LED's everything goes black then nothing. May 26 22:51:14 shabaz: very thorough looking. good work. you should link that on elinux.org/BeagleBone. May 26 22:53:28 dmesg indicates the .dtbo unload happens, its looks like it doesnt afterall; it's not reflected in cat /sys/devices/bone_capemgr.9/slots output thereafter: May 26 22:53:59 great, hope it helps. I'll add a link at the top to elinux as soon as there is a page on this, to state the more recent info is on elinux. I'll add an overall link to elinux/BeagleBone now May 26 22:54:01 and redoing it with ' echo BB-BONE-PRU-01 >/sys/devices/bone_capemgr.9/slots' fails with a write error May 26 22:54:37 ugh, those blue leds are horrible May 26 22:54:52 ketas: black sharpie May 26 22:55:07 i wake up at night because i left one led blinking at 1hz in ANOTHER ROOM May 26 22:55:17 oh jeze pull up your panties already May 26 22:55:17 shabaz, if you don't have an account on elinux.org please ask for one. May 26 22:55:25 anyway .dtbo unload remains a 'research issue' ;) May 26 22:55:26 make sure you troll lots bout blue leds May 26 22:55:33 ketas, thats what they make sharpies. May 26 22:55:56 bleh...you would never believe that engrish is my first language. May 26 22:56:10 bad ejumication then ? May 26 22:56:11 great. will do. I think I applied, will check my e-mail May 26 22:56:19 blue leds: the bikeshed of the BeagleBone community :) May 26 22:56:19 ka6sox: "sharpies for" :) May 26 22:56:43 ketas, yes, I know...I just hit *send* May 26 22:56:45 turned out it was so bright that wall was well lit and it also reflected back May 26 22:57:02 alan_o, +1 May 26 22:57:03 any indicator that leaves shadows is bad :) May 26 22:57:04 mhaberler: if you can get on during the European workweek, panto can tell you for sure. May 26 22:57:28 ah.. workweek, whatzat May 26 22:57:40 can't blue leds be disabled by a few writes to GPIO anyway? May 26 22:57:48 bbb stays plugged in running and blinking away all day / night in my bedroom May 26 22:57:51 what about power May 26 22:58:00 for some people thats 0dark30 till whenever you keyboard dive. May 26 22:58:02 i thought about replacing them May 26 22:58:09 are you referring to the fact that today is sunday? May 26 22:58:09 kfoltman: a few writes with the soldering iron? May 26 22:58:19 aha May 26 22:58:33 ketas: nothing a piece of duct tape can't fix ;) May 26 22:58:53 mine are now orange May 26 22:58:59 heh May 26 22:59:11 can some of them replaced by rgb one? :/ May 26 22:59:13 mru, mranostay: from teal to orange ^^^ May 26 22:59:14 in next rev May 26 22:59:15 I am on a mission to stamp out Blue LEDs from my life. May 26 22:59:19 and some with white May 26 22:59:40 white ones are just blue in disguise... May 26 22:59:51 * alan_o gets out his colorwheel May 26 22:59:52 bed awaits... May 26 22:59:58 nite kfoltman May 26 23:00:04 p00f May 26 23:00:24 Writing BBB-eMMC-flasher-2013.05.20.img to SD card now May 26 23:01:04 shabaz, do you know how fast you can toggle outputs if they're not in the PRU-GPO mode? Is it much slower than the 25MHz you mention? May 26 23:01:19 ka6sox: i wonder if i can paint some phosphor on them? :P May 26 23:01:29 provided i get some May 26 23:01:31 hah May 26 23:02:03 ha! May 26 23:02:14 ketas: how'd you go with FreeBD on the BBB? I still haven't sat down to get it going. May 26 23:02:15 in GPIO mode, I can toggle at 25MHz. In the PRU GPI/GPO mode, it can be full speed, i.e. 5nanosec instructions (200MHz), so realistically you can get 50MHz depending on how tight your assembler code is May 26 23:02:37 I saw 50MHz on my scope, so confirmed May 26 23:02:57 risc: like how to get it running there? May 26 23:03:12 shabaz, the cape I'm working on is theoretically capable of 400mhz...if I decided to buy a 400mhz part. May 26 23:03:17 I've seen the guides on FreeBSD.org, I'm just wondering if you actually got around to getting it up and running? May 26 23:03:29 risc: not yet May 26 23:03:36 risc: waiting for microsd May 26 23:03:38 I've played a bit with Angstrom, and that's 1 nicely undocummented OS... man pages? info about package management? May 26 23:04:06 risc: i ruined mine with opkg upgrade :P May 26 23:04:10 I've setup crosstool-ng for my BBB, and now I want to compile some software, how do I tell make to use the new crosstool binaries? Having trouble finding an answer hope someone in here knows. May 26 23:04:11 shabaz, ah, I misread then. I understood the 25MHz was the fast mode May 26 23:04:15 awesome. It's pretty spectacular that such high speed general I/O out of the chip is possible May 26 23:04:45 ketas: yeah? great! May 26 23:05:06 risc: yes, but it can be restored easily :P May 26 23:05:07 this might really allow me to get rid of the FPGA preprocessing step May 26 23:05:30 ketas: yeah I've got a copy of the default image laying around for when I break stuff :) May 26 23:05:34 shabaz, its theoretically possible to get 200Mb/sec out of a pru. May 26 23:07:07 ketas: I've gotta say Angstrom might the worst documented OS I've ever seen :) - It's a long way from what I'm used to with FreeBSD/OpenBSD May 26 23:07:54 risc: gpio should already work under fbsd so i could play with hw too, instead of just looking how it boots May 26 23:07:55 risc: still? May 26 23:07:55 agree, I meant if people were writing a few other instructions in there, for say a state machine, then 50MHz or so is very easily possible. But you can shift out at full 200MHz too. So basically you can toggle at 5nanosec May 26 23:08:08 risc: video output might be on the way too May 26 23:09:14 alan_o: simple stuff like how does the package management work? given what I'm seeing on this channel... it doesn't :) May 26 23:09:34 im sure koen would love to have some help May 26 23:10:06 risc, its a Source Based Distribution... May 26 23:10:11 risc: I mean you said it twice 5 minutes apart, as though you expected it to have changed in that amount of time... May 26 23:10:30 alan_o: I didn't say it at all, other people are telling you it doesn't work :P May 26 23:10:31 so the theory is that you download the SDK, add your package, and then compile it. May 26 23:10:36 risc: further it's an embedded distro, man pages are a waste to install on the image if they're easily available online. May 26 23:10:53 risc: you complained about undocumented twice in 5 minutes. May 26 23:11:29 so? May 26 23:11:40 outside of you blindly defending the OS what's your point? May 26 23:11:59 my point is that it's annoying when people just show up and throw stones. May 26 23:12:00 I'd be happy to write and expand documentation if I could find any May 26 23:12:38 no ones blindly defending anythign here i dotn think i see someomne blindly comcplaining abotu somethign when he could change to something else even bsd May 26 23:12:57 or wait, are those steps not documented too ? lol May 26 23:13:05 the limiting factor on PRU GPIO wiggling isnt the PRU, its the interconnect fabric, so the clock rate is meaningless May 26 23:13:15 risc: we'd be happy for that! People tell me that elinux.org/BeagleBone is the place to put it May 26 23:13:54 Someones been playing with that on the Pi May 26 23:14:09 doing GPIO/DMA May 26 23:14:31 Directly driving displays May 26 23:14:45 alan_o: pisst May 26 23:14:52 alan_o: see /msg May 26 23:15:05 SpeedEvil, what ? DMA for 6 whole pins ? May 26 23:15:08 * mranostay wiretaps prpplague May 26 23:15:11 there's one guy on the linuxcnc forum doing a stepgen on the pi with DMA, but its a somewhat limited scheme and output only May 26 23:15:13 ? May 26 23:15:17 m_billybob: no - parallel May 26 23:15:24 pruplague May 26 23:15:32 Graphics ones. May 26 23:15:51 SpeedEvil, just my cheapshot way of saying the rpi doesnt have many gpio May 26 23:15:58 ah May 26 23:16:40 In the PRU GPI/GPO mode (mode 5), the bit toggling occurs within one instruction time, i.e. 5nsec, but yes, in the GPIO mode (mode 7) it is slower May 26 23:16:41 err well ,my bad i meant exposed May 26 23:16:46 800*600*18hz or so May 26 23:25:02 SpeedEvil, dont know where this conversation sharted but somene did that with a PRU too. Well supposedly the guy was "featured" on HAD, but apon visiting his site the project page was empty, and the video showing what he did was . . . not very clear abotu what he actually did May 26 23:25:11 started* May 26 23:25:26 hmm May 26 23:38:48 Not going at all my way....now have a mikro SD card I can no longer read and two beaglebone blacks that are non-responsive May 26 23:40:29 Sy_: ouch :( May 26 23:41:08 Not impressed to say the least, I could understand it if I had done something that I shouldn't have, but I haven't, all I've done is try to use it May 26 23:41:17 Sy_, the reflashing process take hours for some reason. May 26 23:41:50 I haven't got that far...SD card is no longer recognised by reader May 26 23:42:11 oh, May 26 23:46:00 odd, can read the mikro SD on macbook pro, but not in windows 7 system May 26 23:48:12 As I understand, the boot button doesn't need to be pressed for very long. 5 seconds after you've plugged in the 5V power source is fine. If you have a serial cable connected, you will see that it has begun booting of the microSD. The lights all flash away, and after almost exactly 45 minutes, all lights are lit. At that point, you can disconnect the power and unplug the microSD. I did this May 26 23:48:12 twice and it worked. I used the in-built SD card reader in the laptop. May 26 23:48:19 I give up, had enough tonight, will try again tomorrow, failing that its all going back into the boxes and back to Farnell May 26 23:49:07 I didn't leave it connected after the 45 minutes (just in case). After all LEDs were lit, I disconnected power pretty much within 5 minutes of that. May 26 23:50:36 If I plug in the microSD into my laptop, I see 4 files on it (ID.txt, MLO, u-boot.img and uEnv.txt) May 26 23:55:10 (my laptop is windows 7) May 26 23:55:23 ok, to unload a .dtbo, you echo the _slot number_ into slots, so echo -6 /sys/devices/bone_capemgr.9 deletes slot 6 (thanks to Brian on the elements14 site) May 26 23:55:47 ah, awesome. I was wondering how to remove a slot too. Thanks! May 27 00:00:51 Just a re-poke, wondering if anyone here has any experience with crosstool-ng before I head out... May 27 00:07:18 mhaberler, can you put that on the elinux.org site as part of the bone doco? May 27 00:08:10 its on shabbaz' page, thats where I got it from; it is also in https://github.com/jadonk/validation-scripts/tree/master/test-capemgr (reading required ;) May 27 00:11:19 I've found I have an elinux account now, so I'll add a pointer. Not very familiar with the site, shall I do it at the "Home Site and Community" section? Morgaine on the element14 site added a link there before May 27 00:12:00 ah, its ok, I've found the Device Tree section there May 27 00:12:07 will update now May 27 00:17:40 For some reason the mikro SD card is not being recognised by my PC anymore, works ok in macbook pro, but in Windows Device Manager just comes up with AM335x USB with an exclamantion mark by it. May 27 00:21:18 sounds like the windows drivers for the SD card reader are faulty to be honest :-( Maybe unistall the windows driver for the SD card reader, and then install them again. Not a great answer I know :-( Or, maybe confirm the SD card reader is fine by trying a different SD card in there (e.g. from a camera or mobile phone). Until you can get to a stage where you can visibly see the 4 files on there, May 27 00:21:18 no point wasting time trying to flash the board again. May 27 00:24:16 shabaz, +1 May 27 00:24:21 tried that, just says driver is up to date May 27 00:24:44 recognise's reader ok with no errors, just will not recognise that SD card is inserted May 27 00:28:55 had enough for one day, ty for help, will try again tomorrow. May 27 00:29:02 *later today May 27 00:33:46 Trying to compile systemd-204, but ./ configure experiences error "Package requirements (dbus-1 >= 1.3.2) were not met: No package 'dbus-1' found." opkg list-installed shows dbus-1 - 1.64, dbus is installed in /usr/local/ and that directory is shown by echo $PATH. What should I check next? May 27 00:39:57 mastiff_, what distro? May 27 00:44:05 goodnight, way past bedtime May 27 00:48:09 ka6sox, it's straight out of the box. I also tried opkg update, and opkg upgrade, but problem persists May 27 00:48:33 Box says Rev A5A May 27 00:50:10 mastiff_, okay so you are talking about building this on angstrom using OpenEmbedded. May 27 00:50:23 s/on/for/ May 27 00:50:58 Yes, it's angstrom and I'm assuming that OpenEmbedded is the version of the GCC toolchain? May 27 00:54:24 its the framework that includes bitbake May 27 00:55:10 what guide are you following? May 27 00:56:10 ok got it,, just read the wiki on bitbake May 27 00:56:21 kk May 27 00:56:51 not following a guide, already went through the quick start stuff May 27 00:57:01 i'm compliling rtl-sdr May 27 00:57:23 so compiling the dependencies for that May 27 01:01:19 ka6sox: I guess I wouldn't say that Angstrom is a source distro. May 27 01:02:03 ka6sox: And leaving a platform in a state that is unusable by the upgrade facilities without a mechanism to warn users prior to use that facility is rather unpolished. May 27 01:02:23 ka6sox: But that answers questions of whether to develop on Angstrom as a distribution choice. May 27 01:04:17 windexh8er, I guess we can fix up the feeds, May 27 01:04:35 yes, I think we can fix the mechanism by just disabling it for now. May 27 01:06:59 mailed out another 12 BCC boards today May 27 01:07:01 not many left May 27 01:07:26 right now its not in shape but thats mostly I think because things have been in a state of flux. May 27 01:07:37 18 boards left May 27 01:07:50 can I buy a couple more? May 27 01:07:59 mastiff_: of course May 27 01:08:02 j/k they are great though May 27 01:08:23 did you order 1? May 27 01:08:37 I got two so I could use one mostly for embedded linux, and the other as arduino replacement May 27 01:08:53 sorry, are we on the saem page May 27 01:09:00 you are talking about a BCC cape? May 27 01:09:06 ya... May 27 01:09:34 I'm just talking about the BBB. Which cape? May 27 01:09:39 ahh. May 27 01:09:41 ok. doh. May 27 01:09:44 makes snese May 27 01:09:47 yup May 27 01:09:55 we are talking about the Blank Canvas Cape May 27 01:09:56 ka6sox: Flux is good - but I think some users may get frustrated early on if they try to follow common directions and end up with a borked board. :) May 27 01:10:11 is there a link to that? May 27 01:10:33 http://ebrombaugh.studionebula.com/embedded/bcc/index.html May 27 01:10:42 i got a batch of pcbs made up May 27 01:10:51 windexh8er, yes, I'm going to try to get this fixed in the next 2 days May 27 01:10:51 and there are some spares left May 27 01:12:17 Oh that's actually the cape I'd most want. I wanna put a FPGA in between a wideband AFE and the BBB. May 27 01:13:42 mastiff_, how wide? May 27 01:14:09 Give me a sec, I'll pull up a link to the IC I'm looking at. May 27 01:14:12 mastiff_: well there you go May 27 01:14:25 we have some spare pcbs May 27 01:14:33 $14 each + $4 post May 27 01:15:21 mrpackethead, where can I order? And do you ship to europe? May 27 01:15:27 sure can May 27 01:15:35 $4 will cover post to europe May 27 01:15:37 I'll order one of those please May 27 01:15:42 hold a sec May 27 01:15:47 i'll find the paypal link May 27 01:15:58 http://www.ti.com/product/afe7225 May 27 01:16:23 Dual 125MS/s ADC and dual 250MS/s DAC all 12-bit May 27 01:16:44 I see we have similar interests. May 27 01:17:34 I also like GaN transistors. May 27 01:17:57 mmmmm May 27 01:19:03 easy question, how do I copy files onto the SD card, is it in /media/card/ ? May 27 01:19:21 depends on your system May 27 01:19:31 https://www.paypal.com/nz/cgi-bin/webscr?cmd=_flow&SESSION=mrcbQsh1ZAStg0NamcecCXDakcSsBaOVbkYx66ZyVWcjMj65o2pRj604Q_m&dispatch=50a222a57771920b6a3d7b606239e4d529b525e0b7e69bf0224adecfb0124e9b61f737ba21b081987dfed5c1e68334a2df49896030ab926d May 27 01:19:32 or are you talking from a running system? May 27 01:19:36 default May 27 01:19:41 thats the link for the bcc cape May 27 01:19:44 sorry May 27 01:20:04 mastiff_, did you put the SD card in before you booted it? May 27 01:20:09 No. May 27 01:20:19 If I do that all the LEDs stay on. May 27 01:20:28 ORLY? May 27 01:20:35 uEnv.txt May 27 01:20:37 .... May 27 01:20:38 I don't have an A5A, I only have a A4 May 27 01:20:41 like it's trying to boot off the SD, but the SD is blank May 27 01:20:58 mastiff one second i have a link for you May 27 01:20:58 sounds like a catch22 May 27 01:21:04 m_billybob, May 27 01:21:04 I think i read that you're supposed to load the SD after you boot. May 27 01:21:07 go for it. May 27 01:21:17 Mastiff, you need a uEnv.xyx file on it May 27 01:21:21 grrr May 27 01:21:28 uEnv.txt file May 27 01:21:33 i have a link for a workign one May 27 01:22:18 Mastiff, this file can not contain any linefeed May 27 01:22:19 s May 27 01:22:28 http://spirilis.net/junk/uEnv.txt wget for the win May 27 01:23:20 you only need that one file on the sd card then it should boot fro mthe emmc fine May 27 01:23:25 so i just need to copy that file onto the SD, and reboot, or do I mount the SD in command line May 27 01:23:52 not sure if angstrom will automount it or not May 27 01:24:00 running "mount" once booted should tell all May 27 01:24:05 ok I'll try it... May 27 01:24:34 ka6sox, what ?! you're not expepriencing bbb love yet ? May 27 01:24:43 experiencing* May 27 01:26:05 fwiw angstrom won't detect the SD at all if you don't install it *before* booting. May 27 01:26:26 rather odd imo, but, hotplug seems to be sketchy atm with 3.8 May 27 01:26:30 with this chip anyway May 27 01:26:47 hotplug is a kernel issue atm May 27 01:26:51 or so ive read May 27 01:26:54 with USB too May 27 01:27:06 you can pop it in and hit the reset button, it'll detect on bootup but naturally you need that uEnv.txt or else it won't boot May 27 01:27:37 dont know whats up but what you say is in the SRM, i dont need to use the boot button ever May 27 01:27:40 m_billybob, I an alpha version that is slightly different May 27 01:27:51 but ive neve rtried booting the emmc with a sdcard in it May 27 01:28:28 ka6sox, ah i just kind of viewed you (and yeah i dont really know you ) as someone who would have them all ;) May 27 01:29:12 not yet!, still hoping mine comes soon. May 27 01:30:08 wonder if anyone with responcability is ever goign ot do a faq page or something May 27 01:30:35 mrpackheat: trying to use your paypal link, but it's giving me cookie errors even though they are enabled and I check for the paypal cookie. May 27 01:30:43 NZ paypal? May 27 01:30:45 for quick fixes to "simple" things like this May 27 01:31:40 Has anybody had any interest in doing a HomePlug (Ethernet over Power) cape? I think it's IEEE 1901. May 27 01:31:41 If your're talking about the SD issue, yeah it would take one paragraph in the Getting Started. May 27 01:33:55 ssorry mastiff_ May 27 01:33:58 might be the wrong link May 27 01:34:01 just a second May 27 01:34:08 https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=PFPRARLC57NTC May 27 01:34:10 try that May 27 01:34:21 works May 27 01:34:25 cool May 27 01:34:33 how many do you want May 27 01:34:35 just 1? May 27 01:34:44 m_billybob, what do you mean? May 27 01:34:46 probably two May 27 01:34:53 sure, theres 2 May 27 01:34:59 i'm just packing them up right now May 27 01:35:05 we can ship up to 5 for $4 May 27 01:35:09 so, its no problme May 27 01:35:12 you have the BOM and solder gerber to send right? May 27 01:35:34 all the details are on erics page May 27 01:35:37 ok May 27 01:35:42 http://ebrombaugh.studionebula.com/embedded/bcc/index.html May 27 01:35:55 i was able to buy everything from Digikey May 27 01:36:05 but i had to substitue the osciallator May 27 01:36:23 the only difference from erics May 27 01:36:28 is that the board is green May 27 01:36:30 not purple May 27 01:38:07 ok, assembly looks very doable May 27 01:38:26 yes, i have build one all buy hand May 27 01:38:35 just with an iron and solder wire May 27 01:39:03 thanks for NOT using 0204 parts May 27 01:39:13 was'nt me May 27 01:39:15 thank eric May 27 01:39:23 i'm jsut a begineer with this FPGA stuff as well May 27 01:39:48 eric is online ( emeb_mac ) is his handle May 27 01:39:52 have you guys seen the Daisho project? May 27 01:40:21 are you going to order it now May 27 01:40:27 yeah May 27 01:40:31 i am just packing up the orders May 27 01:40:37 0204 is too small for hand assy. May 27 01:40:39 so, i'll do yours now May 27 01:40:47 yes! it is way too small May 27 01:40:58 I have been using more 0603 lately tho May 27 01:41:00 unless you *really* have to do it May 27 01:41:08 we have a desing rule May 27 01:41:12 start with 0603 May 27 01:41:25 and then justify why you need bigger or smaller May 27 01:41:36 ordered May 27 01:41:57 eric, theres going to be a few BCC's floating around shorlty :-) May 27 01:42:21 that's a good thing May 27 01:42:59 I'm hoping someone figures out the EEPROM setup to get the SPI port going thru DT. May 27 01:43:21 Chris, i got your order May 27 01:43:33 will be nice and warm up your way. May 27 01:43:45 mrpackethead: how about an assembled one? May 27 01:45:04 dwery.. sadly.. May 27 01:45:06 no. May 27 01:45:35 np May 27 01:45:53 its just too much hassle for me May 27 01:45:59 we manfaucture electronics May 27 01:46:02 and i could May 27 01:46:06 I understand, don't worry May 27 01:46:10 but it woudl distract too many people from real work May 27 01:46:24 can it accept external clock? May 27 01:48:36 Cool, found the hardware docs. May 27 01:52:37 you can drive an external clock in if you want. May 27 01:53:04 mrpackethead, it's been cold spring in US,, anyways, I'll be sailing my boat down to NZ and then North from there by this time next year, so these BCC's are actually boat parts May 27 01:53:15 for radio stuff May 27 01:53:26 nice May 27 01:53:34 what kind of radio? May 27 01:53:54 do you know anything about using that FGPA with gnu radio? May 27 01:54:10 software defined radio May 27 01:54:31 software define all things May 27 01:55:08 actually I think before you got here, i asked this question I'm trying to solve for compiling rtl-sdr on the BBB May 27 01:55:09 Trying to compile systemd-204, but ./ configure experiences error "Package requirements (dbus-1 >= 1.3.2) were not met: No package 'dbus-1' found." opkg list-installed shows dbus-1 - 1.64, dbus is installed in /usr/local/ and that directory is shown by echo $PATH. What should I check next? May 27 01:55:40 mastiff_: I do FPGA-based SDR for my day job. :) May 27 01:55:55 but we don't use gnu-radio May 27 01:56:04 badass! what should I use on a sailboat? May 27 01:56:24 I'm a ham also May 27 01:56:26 depends on what you're trying to do with the radio. May 27 01:56:35 DX through radar May 27 01:56:37 what bands, what modes, etc. May 27 01:56:48 that's a lot of range. May 27 01:56:56 not neccessarily on one device May 27 01:57:00 but on the boat... May 27 01:57:51 so far have a Standard Horizons marine radio with AIS, rtl-sdr, and HackRF May 27 01:59:29 Do you think the BCC board could be potted for marine purposes, or would there be thermal issues? May 27 02:00:46 interesting... May 27 02:00:51 woudl i trust my life on it May 27 02:00:52 no. May 27 02:01:10 just put a heatsink on it before you conformal May 27 02:01:51 more accurately put one on the regulators May 27 02:02:17 on the FPGA and the voltage regulators? May 27 02:02:18 mastiff_, sailing from where? May 27 02:02:21 yes May 27 02:02:36 Chicago back to Chicago the long way May 27 02:02:53 northwest passage? May 27 02:03:24 no, around cape horn, to NZ up to China, back to Panama May 27 02:03:40 5yrs before the mast May 27 02:03:49 !! May 27 02:03:55 what kind of boat? May 27 02:04:17 wait till you get to the furious 50's... May 27 02:04:31 I stayed the winter in my boat May 27 02:04:35 negative 20 May 27 02:04:37 F May 27 02:04:43 nothing like this May 27 02:05:04 what size and Rig? May 27 02:05:44 I've got a diesel vaporizing stove with a peristaltic pump arduino controlled that fires thermoelectric generators and steam collection May 27 02:05:52 Pearson Triton May 27 02:05:54 yawl May 27 02:06:24 29 foot boat May 27 02:06:52 atomvoyages.com is a really famous guy with same boat May 27 02:07:02 sailed twice around May 27 02:07:54 I like Yawl rig May 27 02:08:00 Lots of NZ guys fly to FL buy boats, and sail back. May 27 02:08:26 BIG main and little spanker May 27 02:09:24 solo or with help? May 27 02:09:26 I don't have a kite yet, and just using hank on headsails for now. May 27 02:10:05 unless you have help setting a chute is tough May 27 02:10:30 Mostly solo, sometimes with friends for parts of the trip. Taking my dog also. May 27 02:10:39 and roller furls is best for solo May 27 02:11:10 I'm launching the boat soon, have been rebuilding her for about two years. May 27 02:11:17 kewl May 27 02:11:28 Sailing around the great lakes for the summer May 27 02:11:40 I'd hate to be on the foredeck solo in the 50's May 27 02:12:08 Yeah I wanna be able to press a button to have automatic sail adjustments before that. May 27 02:12:21 What about antennas? May 27 02:12:56 I prefer to resonate the backstay...but SS is a lousy conductor May 27 02:13:21 with a mizzen that is over the transom that can get "interesting" May 27 02:13:27 wood or aluminum masts? May 27 02:14:34 there's always bronze wire rope May 27 02:14:35 http://www.mcmaster.com/#standard-wire-rope/=mx7csn May 27 02:14:42 it's heavier May 27 02:15:20 also five times more expensive May 27 02:15:24 ya May 27 02:15:26 no kidding May 27 02:15:48 also the backstay insulators are expensive May 27 02:16:11 ya, May 27 02:16:31 so most do a lousy 8' whip with a tuner...pretty sucky May 27 02:17:55 you think this TI chip is too fast for the BCC? http://www.ti.com/product/afe7225 May 27 02:19:03 not for the PRU May 27 02:19:08 but you would have to work on it. May 27 02:20:18 I love this marketing schtick...."from baseband to nyquist" May 27 02:20:32 call them and ask them what it means hehe May 27 02:21:05 they'll transfer you a couple times May 27 02:21:45 nice chip for 30USD May 27 02:21:57 but the EVM costs big $$$$ May 27 02:22:55 don't they always May 27 02:24:13 there are other DACs and ADCs that might be easier/cheaper. May 27 02:24:24 ka6sox: so what you know about GPS signals? May 27 02:25:09 that they are down in the noise (on purpose) when they arrive on earth, that they have several codes that they use, that it takes a DSP to decode them. May 27 02:25:46 ka6sox: yes why is it -30db background noise? May 27 02:25:47 oh, and that it takes an instant to turn them off and make them dumb as posts. May 27 02:26:12 something with reducing jamming? May 27 02:26:12 "to prevent our enemies from being able to use them" May 27 02:26:21 ka6sox, sorry got called of for bbq, just mean it would be good if someone actually took the time to document some of the simple (magic hand waving technique) issues on circuitco or possibly somewhere else May 27 02:26:50 m_billybob, elinux.org/beaglebone May 27 02:26:55 thats where all this goes May 27 02:26:56 ka6sox: how is that? May 27 02:27:07 mranostay, remember when it was designed.... May 27 02:27:11 yeah or io may make my own blog and document whatever i know to be right May 27 02:27:29 m_billybob, best not to fracture things anymore. May 27 02:27:37 lets try to centralize things in 1 place. May 27 02:27:50 can link back to whatever all i need ;) May 27 02:27:59 they already have an extensive set of documents for beagle* related things. May 27 02:28:13 but the main doco should be there... May 27 02:28:17 "reference" May 27 02:29:04 ka6sox: so it is a 80's legacy thing? May 27 02:29:31 random unrelated comment: Radio Shack is selling arduino shields that have the wrong pin pitch, it's ridiculous. May 27 02:30:13 mranostay, they watched Independence Day too....

May 27 02:35:38 mastiff_, when I get back from dinner I'll try that May 27 02:36:00 ok,, i'll be around May 27 02:37:12 kelvinji, dunno about that..if you dont' get an answer here the try the ML/forum/googlegroups May 27 02:38:19 okay heading out **** ENDING LOGGING AT Mon May 27 02:59:58 2013
