**** BEGIN LOGGING AT Thu May 23 03:00:00 2013 May 23 03:00:07 I setup a tftp server 4-5 year ago for one of my desktops . . . just find that sort of thing cool in concept May 23 03:00:18 the easiest way to deal with an extra card is a usb sdcard reader cj__ May 23 03:00:35 so, this *is* where the party is at... May 23 03:00:39 you hve to do antything goofy May 23 03:00:47 yeah im finding uboot / uEnv.txt options pretty vast May 23 03:00:56 lots to read though May 23 03:01:05 like everythign else where the bbb is concerned May 23 03:01:14 heya gnomad May 23 03:01:46 if you get a uSD card usb adapter you just plug it in and then it just automounts the sdcard May 23 03:02:15 sdcard hotplug is currently broken in the kernel i think May 23 03:02:24 was what i was jus treading anyhow May 23 03:02:48 i was able to unplug one and plug in another and it seemed to do the right thing May 23 03:03:00 the micro sd card slot ? May 23 03:03:05 no May 23 03:03:15 i'm talking about one of those usb sd card readers May 23 03:03:22 you plug it into the host usb port May 23 03:03:27 and then plug the card into the reader May 23 03:03:31 ok sorry i mean uSD slot hitplug is currently broken in the kernel <--- is what i was just reading May 23 03:03:33 pop in and out May 23 03:03:38 hotplug but yeah May 23 03:03:49 yeah i was actually reading about the mmc interface thing and it seems crippled May 23 03:03:52 4 bits May 23 03:03:57 eeek May 23 03:03:59 because it share lines with something May 23 03:04:34 brb May 23 03:04:46 this way you also don't have to dick around with uEnv.txt files on your uSD cards May 23 03:06:29 http://compare.ebay.com/like/251187352185?var=lv<yp=AllFixedPriceItemTypes&var=sbar May 23 03:06:34 something like that May 23 03:07:12 that is actually the one i have but i think i got it at bestbuy May 23 03:18:06 I have several usb drives May 23 03:18:13 PATA and SATA May 23 03:22:07 * m_billybob is still looking for a suitable toolchain to serve his purposes May 23 03:22:19 Rick so why ntfs support ? May 23 03:22:39 arent you like al linux ? May 23 03:22:41 on the list May 23 03:22:56 of things to try May 23 03:22:59 ah May 23 03:24:29 one of the thigns id like to try, just for the geek factor is nfs / TFTP netbooting May 23 03:25:27 granted 10MB/s disk access would be slooooooooow May 23 03:25:50 it is the 90's again with thin clients May 23 03:25:58 ;) May 23 03:44:18 ka6sox: you awake? May 23 03:47:22 mrpackethead, for small values of awake May 23 03:47:33 i lost your mailing details May 23 03:47:58 Rickta59: 90s? try the 70s May 23 03:48:08 dumb terminals May 23 03:49:05 mid 80s then May 23 03:49:12 blit terminals May 23 03:49:27 So, is a web browser a dumb terminal these days? May 23 03:49:48 no they are the 3270s May 23 03:50:09 and if so, what does it mean that a web browser is the most resource-intensive application I run on my desktop? May 23 03:54:53 bleh..3270's May 23 03:55:05 crappy and very expensive terminals.... May 23 03:55:06 Capes! FPGA capes! get your capes.. May 23 03:55:17 not many of these to go... May 23 03:55:21 get in while you can. May 23 03:55:29 :-) May 23 03:55:44 mranostay: you need one of these May 23 03:56:26 need time May 23 03:56:37 kinda busy.. new job and all May 23 03:56:43 lol. May 23 03:56:51 * mranostay hooks up mythboard as ka6sox calls it May 23 03:56:58 somebody gave you a job May 23 03:57:02 ??? May 23 03:57:10 poor poor souls. :( May 23 03:57:18 mrpackethead, which cape ? May 23 03:57:28 BCC May 23 03:57:38 * m_billybob doesnt grok May 23 03:57:40 http://ebrombaugh.studionebula.com/embedded/bcc/index.html May 23 03:58:00 ah right the spartan 3A capes ? May 23 03:58:06 yup May 23 03:58:11 mrpackethead: yeah Intel did May 23 03:58:12 and its just PCB's May 23 03:58:12 mranostay, send it to me and I'll believe it exists...otherwise...it is a Myth. May 23 03:58:17 ah yeah May 23 03:58:58 mranostay: so how is the mail room at intel? May 23 03:59:07 mranostay: congrats! May 23 03:59:31 mrpackethead have you done any btc mining with those ? May 23 03:59:39 * m_billybob has one track mind May 23 03:59:57 i dont' think an FPGA is a very efficent thing to use for bitmining May 23 04:00:18 uh.... May 23 04:00:21 they've been used as such but not arguing May 23 04:00:23 I was browsing intel jobs last year and noticed the lab tech jobs required a bachelors!? May 23 04:00:35 mrpackethead: expensive May 23 04:00:38 that was for Lab Rats... May 23 04:02:00 m_billybob: how efficent are they? May 23 04:02:00 m_billybob: there's a nice table at one of the bitcoin wikis that covers cpu, gpu, fpga, and asic. power cost and all. fpga are decent (if you buy a crazy expensive one), but everything gets absolutely smoked by the asics. May 23 04:02:16 PRU_EVTOUT_2: that was my understanding May 23 04:02:24 PRU_EVTOUT_2: Except in the power/heat department. ASICs suck back the power and pump out heat. May 23 04:02:31 mrpackethead spartan 3A im not sure but a spartan 6 LX150 is it ? does 95MH/s May 23 04:02:58 those are like $175 each FPGA May 23 04:03:00 Xilinx XC3S200AVQ100 Spartan 3A FPGA with 200kgates, 16 Multipliers and 288kb RAM. May 23 04:03:10 theese are $10.20 each May 23 04:03:15 yeah May 23 04:03:27 Shadyman: there's no difference in the way electrons require power to move around in asics of fpgas. ;) May 23 04:03:56 much cheaper the spartan 6 i read abotu has like 64MB ram ? going from my memory here, and is not always accurate May 23 04:04:08 PRU_EVTOUT_2: True, but the ASICs are currently at, I think, a 120nm process, vs 30ish for fpgas May 23 04:04:13 Shadyman: power per coin mined is *much* less though. May 23 04:04:24 at least the bitcoin asics on the market May 23 04:04:38 process isn't at all enough to know. May 23 04:04:49 well, no May 23 04:04:56 ASICs are far more eficient May 23 04:05:07 at churning out bitcoins, yes May 23 04:05:13 especially considering fpga are general purpose, and assume signals need to get across the whole chip, no matter what. May 23 04:05:22 well of course they're by far less G May 23 04:05:23 total $ / bitcoin is what is importnat May 23 04:05:34 GP* May 23 04:05:37 mrpackethead: indeed May 23 04:05:57 somehow i dont' think that ratio will be good for a BB and a Spartan 3A May 23 04:06:06 nope May 23 04:06:18 butterfly laps has perportedly 5GH/s asic miners, and those are the teensy ones May 23 04:06:19 mrpackethead: if you use an electric heater in the winter, it's all free :D May 23 04:06:25 butterfly labs* May 23 04:06:30 m_billybob: butterfly labs is late to the game. May 23 04:06:33 (assuming you only mine in the winter) May 23 04:06:57 m_billybob: avalon's miners are ~66Ghash/s IIRC May 23 04:06:57 (and assuming your mining power is <= your houses heat loss. May 23 04:07:09 and shipped months ago May 23 04:07:10 Shadyman, whatever the case, backorders would be the killer for late players May 23 04:07:22 lol, i think everyone is a late player at this point. May 23 04:07:25 with butterfly labs May 23 04:07:40 avalon won, and difficulty is skyrocketting May 23 04:07:51 so there's that :/ May 23 04:07:55 Shadyman, also the jalapeno 5GH/s model is !$300 usd May 23 04:08:04 ~$300* May 23 04:08:16 would pay its self off at current difficulty in a week May 23 04:08:18 m_billybob: True, but 66Ghash/s for $1500 vs 5Ghash/s for $300 May 23 04:08:26 but by the time you get one . . .yeah anothe story May 23 04:08:40 ^ that May 23 04:08:59 also, asics can't ever be upgraded without just tossing entire boards May 23 04:09:13 fpgas you just update and go May 23 04:09:25 ive read and by no means from an accurate source if you order one now from butterfly labs . . . you might be able to expect to get one this time next year May 23 04:09:31 heh May 23 04:09:39 the way BFL's been dragging its feet, it's not surprisng. May 23 04:09:56 *pre-order* is no use to me May 23 04:10:06 from the outside looking in, it seems they're a mom and pop operation May 23 04:10:24 10-20 employees maybe hand soldering . . . May 23 04:10:30 and are awfully lacking on the PR front May 23 04:10:34 but big question May 23 04:10:52 if they'remaking these and able to sell for this price, why not just mine with the hardware ? May 23 04:11:03 always that questions been in the back of my mind May 23 04:11:06 heh May 23 04:11:25 because then they'd need tobe using their own money for R&D and construction May 23 04:11:34 preorders essnetially paid for all of that May 23 04:11:40 payback would be very quick May 23 04:11:48 yes, but you'd still need capital May 23 04:11:50 ah so in effect a quickstarter May 23 04:11:57 essentially May 23 04:12:11 guess that makes perfect sense May 23 04:12:41 they legit from what i can tell but that one question always nagged me lol May 23 04:13:00 [SOLVED] May 23 04:13:02 ;) May 23 04:16:28 Has anyone in here attempted linaro on widnows yet ? May 23 04:16:33 Just upgraded my brand new beagleboard black... now it's asking for a password for one of two users: mpd and xuser.. I have no idea on either May 23 04:16:50 Is there a supposed default login? May 23 04:16:54 jonmasters_ can you ssh in ? May 23 04:17:06 err May 23 04:17:10 let me try real quick May 23 04:17:10 Jononomous May 23 04:17:54 if you can with root/root create a new user then you should be good May 23 04:18:25 * m_billybob read that off the groups ~ last week May 23 04:18:35 Thanks m_billybob, worked like a charm. Guess I didn't expect SSH to work given that hitting 'Other' and using root didn't work May 23 04:18:40 Much appreciated sir May 23 04:18:46 no problem :) May 23 05:04:00 Hi, is anyone on right now? May 23 05:10:30 no May 23 05:11:10 nope May 23 05:11:49 am not here too May 23 05:31:04 Hi, I'm having some trouble building Angstrom from scratch using the instructions provided on their site, is anyone familiar with this process? May 23 05:34:11 elaborate on 'some trouble' and you'll find out. May 23 05:34:57 Marc_SSL: why do you want to do that May 23 05:35:34 dm8tbr: I think it may have to do with the Filename limit on eCryptfs. I get an error saying that it "Failed to create a file with a long name in TMPDIR" May 23 05:36:07 you are building on top of an ecryptfs? May 23 05:36:58 mrpackethead: Honestly, I'm still somewhat fresh at Linux and I've hit a huge problem with the project I'm trying to work on. I'm trying to get Angstrom to run on the BeagleBoard-xM with the MT9P031 camera (with fully functioning drivers, e.g. adjusting exposure, etc) and OpenCV. And I've had some issues with the package builder Narcissus provides May 23 05:37:16 dm8tbr: I'm using a netbook and I think it may have ecryptfs May 23 05:37:33 then you might want to build outside of that? May 23 05:38:30 I'm limited to a netbook for now, is there anyway I can circumnavigate this? Would I have to partition my harddrive? May 23 05:39:04 depends on where the ecryptfs is. if it's just your home, then build in e.g. /opt May 23 05:39:10 if that has enough space May 23 05:39:27 or create a new directory in /home that is not under ecryptfs May 23 05:39:29 Let me try doing it May 23 05:39:44 Alright, how do I do that? May 23 05:42:16 first world problem lost a geiger tube May 23 05:43:08 mranostay: where have you looked? May 23 05:44:21 encourageing momenet May 23 05:46:45 Linux arm 3.8.13-bone18 #1 SMP Thu May 16 18:01:50 UTC 2013 armv7l GNU/Linux May 23 05:46:53 happy happy May 23 05:49:30 mranostay, look either in the kitty litter or the Gun Cases... May 23 06:01:33 mrpackethead debian ? May 23 06:06:44 yarn May 23 06:09:08 moaning av500 May 23 06:41:11 surprised to discover that only the first 10 or so minutes of the 45 minute reflash is actually copying files from the tarball, the rest is some silly gconf stuff or something May 23 06:42:04 m_billybob: yes May 23 06:44:19 something is overwritiny hostname with crap on startup May 23 06:44:26 avahi? May 23 06:46:52 gutemourning May 23 07:00:20 this is great news. Current kernel on a capable bit of hardware, wuth a good os May 23 07:00:24 what more can i aske for. May 23 07:02:44 mrpackethead: kernel.org says 3.9.3 is current stable ;-) May 23 07:04:38 russell--, stability is more than just a number...chasing kernel revs is very annoying to someone trying to get something to work and continually having to remerge and redo :P May 23 07:04:51 ka6sox: yup!!! May 23 07:04:54 s/remerge/rebase May 23 07:05:32 now got to figure out how to get the os on the emmc May 23 07:05:35 rather than the sd-card May 23 07:05:45 well, he said "current" May 23 07:06:02 3.8 is current enough for me May 23 07:06:06 i was using 3.2 May 23 07:06:16 russell--, I have a device I was working on today that has 2.4.20 on it...and it works FINE...every day 24/7 May 23 07:06:22 lol May 23 07:07:26 debian@arm:~$ uptime May 23 07:07:26 07:07:13 up 7 min, 2 users, load average: 0.00, 0.08, 0.06 May 23 07:07:34 russell--, and "stable" means stable for *this week* or *these 3 days*...so its NOT really "stable" May 23 07:07:38 wahoo.. 7minutes updtime May 23 07:09:21 mrpackethead: you are familiar with emmc.sh? May 23 07:09:30 no. May 23 07:09:31 not yet May 23 07:09:32 :-) May 23 07:09:51 it's the crazy flasher script that the flasher images use May 23 07:09:52 but i might be shortly right? May 23 07:09:59 yup May 23 07:10:17 maybe worth reading if not necessarily executing May 23 07:14:21 looks like koen just drops a fresh MLO, u-boot.img and Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone.rootfs.tar.gz into /build in a flasher sd card image and away you go (maybe) May 23 07:16:35 but it uses that angsum thing May 23 07:16:48 http://www.youtube.com/watch?v=KaOC9danxNo&hd=1 Still worth a rewatch May 23 07:17:08 Evening Col. May 23 07:25:48 hmm. the /etc/systemd/system symlink of default.target -> multi-user.target doesn't seem to work the same in the 5/20 image May 23 07:35:11 a wonderfull JIHAD everyone!

May 23 11:15:11 Okay, I got read TRM for 335x family and found that I can use FAT as well as GPT May 23 11:15:37 GPT? May 23 11:15:58 Silentjet, there is a working uboot console on the BBB alreaday May 23 11:16:04 what are you trying to do exactly? May 23 11:16:15 Silentjet: my experience was to plug a USB2serial cable on J1 May 23 11:16:19 it worked May 23 11:16:40 have you plugged it in? and plugged USB<->TTL cable in? May 23 11:16:42 Is it possible to use MicroUSB connection ? May 23 11:16:55 not from the board directly May 23 11:17:03 the FTDI chip has been removed May 23 11:17:37 jackmitchell: thanks, that is my answer what I got failed so many times :) May 23 11:17:38 the console is now on the 6 pin-header May 23 11:17:39 *why May 23 11:17:46 yes May 23 11:17:49 Silentjet: to make it cheaper May 23 11:18:13 to sell extra cables :) May 23 11:18:23 to make it more like rpi May 23 11:18:33 well..... May 23 11:19:49 I had wait for BBB more then 4 weeks... May 23 11:20:11 another more 4 weeks for serial - really cool :) May 23 11:20:37 why 4 weeks? May 23 11:20:45 Silentjet: just buy the serial cable locally May 23 11:20:58 Silentjet: and research what extra components you will need next time May 23 11:21:02 is this standart FTDI cable ? May 23 11:21:05 yes May 23 11:21:10 or prolific May 23 11:21:19 if you are brave May 23 11:21:48 If it is standart then I guess it is not a big deal to buy locally May 23 11:21:51 av500: I'm still waiting on my BBB's from Farnell, that's been close to 4 weeks now :/ May 23 11:21:51 thanks a lot May 23 11:22:46 well, any 3.3V serial cable will do May 23 11:22:56 USB or not May 23 11:28:56 a max232 with a couple of wires... May 23 11:28:57 hmm that explains a lot. why is it still shipped with ftdi drivers than... May 23 11:29:08 wave_: same image May 23 11:29:13 KotH: MAX3232 May 23 11:29:20 av500: newfangled stuff! May 23 11:31:06 KotH: got for a MAX12232 then :) May 23 11:31:17 -t May 23 11:31:24 it does not even need caps May 23 11:32:19 there aint no such chip May 23 11:32:35 not yet May 23 11:32:44 released tomorrow May 23 11:32:53 KotH: exactly May 23 11:42:34 hi all May 23 11:46:18 grüezi May 23 11:46:21 how may we abuse you?

May 23 12:04:13 KotH: urg nonetheless May 23 12:05:52 koen: at linuxtag? May 23 12:05:58 no :( May 23 12:06:10 fish related deadlines May 23 12:06:43 try a grenade May 23 12:09:07 I doubt you're missing much May 23 12:09:10 all that talk about rain May 23 12:09:15 and it starts to rain here May 23 12:09:18 hm, tuna salad May 23 12:09:35 last few years sucked May 23 12:11:59 move somewhere with a better beer May 23 12:13:16 beer is good here May 23 12:18:26 koen: hail here too, odd time of year May 23 12:25:36 sun here... odd time of the year too... May 23 12:25:48 it should be snowing May 23 12:31:55 it is, if you live in > 1000m May 23 12:34:13 weather forcast tells us that it'll be snowing down to 600m this weekend May 23 13:10:15 we broke the boat May 23 13:10:23 I suppose I can windsurf in the rain May 23 13:10:50 or rainsurf in the wind May 23 13:11:05 heh May 23 13:11:24 I need post photos from the dismasting on g+ May 23 13:14:18 anyone get unity working on beaglebone black May 23 13:17:13 don't you get that for free if you install ubuntu OurMaNdO|W ? May 23 13:18:14 not on the beaglebone black May 23 13:18:21 unless you count curses as a cost May 23 13:18:25 u get a console and lxde if u want May 23 13:18:54 bizarre .. the reason i stopped using ubuntu was because of unity May 23 13:20:41 u can put just about any flavor of linux u want im just curious what desktop environments the beaglebone can support May 23 13:21:14 also 1337133n00X? May 23 13:26:53 nope, that's kanged and needs key May 23 13:26:54 Crofton, at least everybody is smiling after the fact. May 23 13:29:27 mdp: not the guy that fell into the water May 23 13:30:02 well, that's never fun May 23 13:30:37 I had that deliberately done to me in very cold lake erie when I was being taught to sail..as a kid ;) May 23 14:16:34 mdp, there was less smiling after the beer ran out May 23 14:17:15 Pete was holding on to the shroud that failed and went in May 23 14:17:27 we were glad to see his head come back up May 23 14:17:40 Crofton, yeah, lack of happy fuel. May 23 14:17:56 I'll bet, heh May 23 14:22:38 Crofton, what size boat was that? May 23 14:23:01 too small May 23 14:23:16 they'll gonna need a bigger boat May 23 14:29:22 av500, that looked like a 2-3 Six Pack boat...tops. May 23 14:38:23 boats are measured in sixpacks? May 23 14:41:58 hehe May 23 14:43:34 a "sixpack" in boating terms refers to the US coastguard exam, that allows you to take upto 6 passengers out on a boat May 23 14:48:08 ka6sox, Flying Scot, 19 ft May 23 15:05:41 * KotH curses usb May 23 15:05:59 1h debugging to find yet another corner case... May 23 15:06:26 KotH, better than trying to debug musb :( May 23 15:07:36 KotH: USB is a corner case May 23 15:07:55 what I love most about the musb driver is that they try to fake the HW state machine of EHCI in SW May 23 15:08:12 because, after all the HW state machine of EHCI works, right? May 23 15:08:24 ka6sox-away: from what i heard, that must be worst usb hw implementation ever May 23 15:08:32 no May 23 15:08:34 ka6sox-away: so i'm glad to not have had to touch it May 23 15:08:51 just the one with the most false expectations into it May 23 15:08:58 av500: ? May 23 15:09:26 ka6sox-away: oh.. and the code was now working for approx 5y w/o problems...until we connected it to this one pc which does things slightly different.... May 23 15:09:27 my problem is that I have a client who is having issues with it and pulling their hair out. May 23 15:09:41 ka6sox-away: i hope you've a beagle480 May 23 15:09:58 its an 8168 board. May 23 15:10:25 ka6sox-away: why does everybody have that 8168 board May 23 15:10:30 mdp: !!!!!!!!!!! May 23 15:10:34 not that kind of beagle, the other kind of beagle...the ones from totalsoft :) May 23 15:11:11 av500, I dunno, I just know that they really don't want to have to requalify a *different* kernel as its a medical device... May 23 15:11:17 Hello, I have a question about the UART 3 on the BB xM. I use the UART2 (on the expantion header) with my programm and it works. I would need one more uart, so I want to try to use the UART3. I set the pins to uart3 for rx and tx (I only use these) . But it doesnt work. I hope one of you can tell me what Im doing wrong. May 23 15:11:52 proesel, insufficent data to process request. May 23 15:12:02 hi ka6sox-away May 23 15:12:10 morning panto May 23 15:12:28 bb30m...headed to the Hilltop :) May 23 15:13:58 Hi ka6sox-away. What data have I to give to you ? May 23 15:14:10 which distro you are using. May 23 15:14:15 ka6sox-away: hmm... how did they get the linux kernel quallified for medical in the first place? May 23 15:14:17 and kernel May 23 15:14:32 KotH, ancillary use... May 23 15:14:39 but still needs Qual. May 23 15:14:55 ah..ok May 23 15:14:56 yes May 23 15:14:57 i know May 23 15:15:02 * KotH is doing medical as well... May 23 15:15:44 KotH, question, could you qualify a PRU program for medical use May 23 15:15:54 while linux is for ancillary use? May 23 15:16:10 yes, thats been done with some FPGA stuff I did. May 23 15:16:23 av500, for some reason people love the torture of working with 81xx May 23 15:17:18 mdp: send me one :) May 23 15:17:22 I use Ubuntu 12.04 Linux arm 3.7.8-x8 #1 SMP May 23 15:17:34 panto: not really May 23 15:17:44 what would be the snag? May 23 15:18:09 panto: the problem is you have to proove that the PRU programm cannot be negatively influenced by the system running on the arm core May 23 15:18:35 panto: with the PRU architecture this is not possible (the arm core can write directly into the PRU memory w/o the PRU being able to stop it ) May 23 15:18:45 KotH, err, not really May 23 15:18:54 av500, I gotta hold on to my one-and-only ;) May 23 15:19:14 you can forbid access to the PRU via the MMU May 23 15:19:16 mdp: how much chocolate do you need to get me one of those 8168? ;) May 23 15:19:31 lol May 23 15:19:36 heh May 23 15:19:51 not another choc whore. May 23 15:19:57 panto: but it's the arm core that sets teh MMU May 23 15:20:01 * m_billybob is a choc whore May 23 15:20:10 yes May 23 15:20:17 panto: and there lies the problem May 23 15:20:26 * mdp contacts TI to shower #beagle with 8168 evms May 23 15:20:42 panto: you have to proove that the arm core can under no circumstances influence the PRU in any negative way May 23 15:20:55 panto: for that you would have to proove that the MMU is always set correctly May 23 15:21:35 panto: ie get a full medical review of the linux mm code May 23 15:21:42 right, good luck with that May 23 15:21:46 panto: and you'd have to switch of /dev/kmem May 23 15:22:06 why run linux on the ARM at all May 23 15:22:11 use a proper OS like Minix May 23 15:22:20 one that never crashes May 23 15:22:25 lol May 23 15:22:26 aren't there different classes of medical devices? May 23 15:22:39 panto: yes, oral and rectal May 23 15:22:45 proesel, you might need to go to the Forums/googlegroups/mailinglist. May 23 15:22:45 there are, depending on how dangerouse a malfunction is May 23 15:22:46 panto: depends on your country, but yes May 23 15:22:53 there are at least three May 23 15:23:07 panto: the least dangerouse category belongs to spatulas :) May 23 15:23:08 av500, you can't crash something which has no drivers for interfacing with the outside world :) May 23 15:23:19 this one goes inside so its kinda scary. May 23 15:23:19 panto: see the brilliance? May 23 15:23:28 ka6sox-away: implant? May 23 15:23:34 ka6sox-away: the whole 8168? May 23 15:23:35 ka6sox-away: with linux running on it? May 23 15:23:51 what if there are fail-safes? May 23 15:23:52 it was designed by Aliens...any more questions? May 23 15:23:57 I hope the EVM has rounded corners May 23 15:24:06 panto: you have to have fail safes anyways May 23 15:24:07 external hardware watchdog circuit May 23 15:24:24 panto: but you still have to proove that nothing can go terribly wrong and kill someone May 23 15:24:26 yes, I'm just trying to see where the borderlines are May 23 15:24:34 KotH: use tests, lots of test May 23 15:24:38 animal and volunteers May 23 15:24:48 right, we're not talking about life threatening devices May 23 15:24:58 panto, depends May 23 15:25:04 let's say it's something like a blood sugar monitor May 23 15:25:04 panto: even if the watchdog doesnt fail, you have to ensure that between the program failure and triggering of the watchdog, it doesnt explode May 23 15:25:25 for personal use, not for hospital and such May 23 15:25:26 panto: oh.. these are "easy" to get trough May 23 15:25:29 KotH: Don't you have to ensure that patient condition cannot get worse? May 23 15:25:49 KotH, right, we're not talking pacemakers May 23 15:26:35 panto: well.. one of our projects we are currently doing is akin to a microwave oven that you attach to your skin May 23 15:26:46 always warm May 23 15:26:58 ka6sox-away: thanks I will have a look. one more question, do I have the oportunity to switch parts from the BB off to save energy? May 23 15:27:00 panto: it is not a pacemaker, but it can cause severe burns if it malfunctions May 23 15:27:01 never cold feet in bed again May 23 15:27:07 KotH, err, why? cannibalism is a big market? :) May 23 15:27:16 proesel: yes, the big square part :) May 23 15:27:40 proesel, depending on kernel and other bits you *may* be able to do this. May 23 15:27:40 proesel: XM is not really power save friendly May 23 15:27:55 av500, no rounded corners, sorry. it does have active cooling though May 23 15:28:01 good May 23 15:28:19 panto: i'm not allowed to talk about that :) May 23 15:28:35 I know :-) Is there a " keyword " that I can google ? May 23 15:29:41 av500, I've seen the "probe" and I wouldn't want to know if it was being used and where. May 23 15:30:04 so gimme the Gas! May 23 15:30:23 * KotH gives ka6sox-away a bottle of acetylen gas May 23 15:30:33 KotH, wrong gas May 23 15:30:43 Root Beer flavoured. May 23 15:30:43 it's a gas May 23 15:30:47 heh May 23 15:30:59 laters... May 23 15:31:04 have fun May 23 15:32:27 panto: btw: the way how we keep the thing trough medical review is to use a small uC to handle the microwave source and the security functions that communicates over SPI with an uP that runs linux for the UI May 23 15:32:37 s/keep/get/ May 23 15:32:49 KotH, that's what the PRU can do May 23 15:33:13 yes, but you cannot kill a uC over SPI May 23 15:33:25 not even with shorts May 23 15:33:55 while it's easy to kill the PRU when something is running havoc in the kernel May 23 15:34:17 and it makes the system easier to review May 23 15:34:25 the uC code is a couple 1000 loc May 23 15:34:47 yo prpplague May 23 15:36:40 XorA: ho ho and bottle of bajan rum May 23 15:42:31 ....Is there any Fat32 library for Qt? Or any port has been made before?.... May 23 15:42:54 damn, jkridner_ answered already May 23 15:43:00 I was to sell him one May 23 15:44:44 retirement project May 23 15:53:27 heh May 23 15:53:57 * mranostay hurls binary blobs at panto May 23 15:54:54 * mdp flings dead am335x-evms at mranostay May 23 15:55:44 * mranostay hurls deads pandas May 23 15:56:25 borads May 23 15:57:21 * av500 hurls dead DM310 EVMs May 23 15:57:28 they were dead on arrival May 23 15:58:02 oh right whois doesn't work because of the proxy.. grrr. May 23 15:58:03 anyone know of a version of opewnrt that would run on the beaglebone black? I've searched high and low May 23 15:58:20 is there a linux port of openwrt? May 23 15:58:41 lol May 23 15:59:12 @av500 openwrt is linux if I'm not mistaken May 23 15:59:16 openwrt is linux May 23 15:59:26 well, the BBB does run linux May 23 16:00:01 yes it runs linux but I haven't been able to find a version of openwrt for omap35xx May 23 16:00:31 you should probably ask on #openwrt or #openwrt-devel May 23 16:00:40 ah, thanks for the tip russell May 23 16:01:01 rolex: the BBB does not use omap35xx May 23 16:01:16 all you need is a kernel May 23 16:01:22 user space is mostly interchangeabkle May 23 16:01:33 mmap all things May 23 16:03:18 as long as it's ARM userspace May 23 16:03:35 there's plenty of MIPS hardware in the router world May 23 16:03:49 dm8tbr: and openwrt lost their source code? May 23 16:04:00 just saying May 23 16:04:22 I could have sworn that the BBB used omap35xx av500: heading to wiki May 23 16:04:31 BB does May 23 16:04:34 er May 23 16:04:40 beagleboard does May 23 16:04:48 bone uses AM335x May 23 16:10:01 you were right av500, thank you for correcting me May 23 16:12:24 masta: ping May 23 16:12:59 prpplague: pong May 23 16:19:28 rolex: never doubt av500 again ever May 23 16:19:49 mranostay: I have learned my lesson haha May 23 16:20:14 my boss had said it was the omap35xx so I took his owrd for it May 23 16:20:20 fire him May 23 16:20:23 haha May 23 16:21:00 I'm a lowly intern, doubt I have that power May 23 16:21:33 av500: fat32 for qt? May 23 16:21:41 av500: that doesnt make sense May 23 16:22:44 rolex: never trust anything your boss says May 23 16:22:48 rolex: never ever May 23 16:23:15 our chief R&D once said that GBit ethernet is half duplex only... May 23 16:24:28 KotH, ever hear about the Peter Principle? May 23 16:24:50 yeah May 23 16:25:22 he's one of the guys who accumulated a lot of facts, but very little knowledge over the past couple of decades May 23 16:27:00 Deleting 'truths' from your memory can be damn hard. May 23 16:27:26 nah.. it's easy...once you get to the habit of questioning everything you know May 23 16:27:45 thruthiness trumps truth every time May 23 16:28:35 knowing things isn't what bosses are for May 23 16:28:50 what are they for again? May 23 16:29:03 signing timecards or something May 23 16:29:41 well.. unlike the average japanese company, where decisions are usually made at the lowest levels, european companies do decisions at the highest levels... where the "bosses" are May 23 16:30:33 * russell-- conjures image of a boat tossed on a tempestuous ocean May 23 16:33:22 http://feedproxy.google.com/~r/brainsciencepodcast/~5/vW1YXte6J0o/43-brainscience-Burton.mp3 - is relevant. May 23 16:33:51 On the origins of certainty in the brain - and why it's not a perfect guideline to truth May 23 16:34:11 SpeedEvil: is that available as text as well? May 23 16:34:37 yes May 23 16:34:48 where? May 23 16:35:11 http://brainsciencepodcast.com/episode-transcripts - episode 42 May 23 16:35:24 domo May 23 16:35:47 Highly HiHighly recommended podcast. I even donated! :) May 23 16:39:41 hi May 23 16:40:14 i'm continue trying with my new BBB, and now have another question May 23 16:40:26 Is it related to ducks? May 23 16:40:43 dogs i guess May 23 16:41:19 SpeedEvil: not that interesting... May 23 16:41:22 Does u-boot support BBB mUSB port ? May 23 16:41:27 Well, I like it. May 23 16:41:28 SpeedEvil: i've heard about most of that stuff already in much more detail May 23 16:41:40 SpeedEvil: but then... i study taht stuff :) May 23 16:41:45 Ah. :) May 23 16:42:45 I'm looking inside u-boot sources and still could not find exact answer May 23 16:42:59 may be because lack of u-boot experise xD May 23 16:43:41 KotH: Well, if you work out how memory is actually stored... :) May 23 16:43:53 So i'm trying to start u-boot in fastboot mode May 23 16:44:00 mru: does using -mthumb for C and assembly code, place linker restrictions that assembly code functions called must be at certain aligned boundaries? May 23 16:44:20 When, making calling a function in assembly from C code May 23 16:44:39 Are you sure thumb is fully supported on the processor? May 23 16:44:57 Cortex-a8 May 23 16:45:11 joel_: no May 23 16:45:20 SpeedEvil: if i do that, you are sure to hear about it :) May 23 16:45:49 SpeedEvil: but psychology is just a hobby for me.. nothing i do very "seriously" May 23 16:45:50 mru: so C code should be able to jump to 2-byte aligned function boundaries? ok. May 23 16:46:45 some one in the team claims placing ".align 5" in assembly fixes an issue where the linker jumps to the wrong address if they didn't .align May 23 16:47:14 hmm... May 23 16:47:34 the assmebly code must be aligned, otherwise it cannot be jumped to May 23 16:47:53 but then, i would expect the assembler to do that automagically May 23 16:47:53 KotH: why not? May 23 16:48:01 uhm... May 23 16:48:25 because the ARM ARM restricts code execution to addresses that are properly aligned May 23 16:48:33 (simplifies the cpu design) May 23 16:48:48 heh May 23 16:48:55 i'm not sure but think that this still holds for the most modern arm incarnations May 23 16:48:57 aren't most arch that way? May 23 16:49:02 mranostay: nope May 23 16:49:12 mranostay: CISCs didnt have such alignent restrictions May 23 16:49:42 mranostay: and afaik most CISC archs still dont have alignment restrictions on code May 23 16:49:58 why is that? instruction sizes? May 23 16:50:04 as the code can has a varying length from 1 byte to anything May 23 16:50:39 IIRC x86 has some ridiculous maximum instruction sizes May 23 16:50:45 i dont of any CISC arch that has an even address code alignment restriction May 23 16:51:00 panto: what was it? 15 bytes? or so? May 23 16:51:08 yes, 15 May 23 16:51:09 panto: you mean ridiculously cool right? May 23 16:51:11 * panto googles May 23 16:51:16 mranostay, lol, yeah May 23 16:51:31 so cool you have to wear a jacket May 23 16:51:42 x86 all things! May 23 16:51:42 Question, does anyone have any compiler / linker option setting I can look at ? I am trying ot get a feel for what all i should be setting. May 23 16:52:17 m_billybob: let that handle your build environment May 23 16:52:27 m_billybob: dont touch anything unless you know what you are doing May 23 16:52:45 so linaro will autoset what i need then ? thats pretty cool. May 23 16:53:06 KotH, thanks much. May 23 16:53:15 meh.. english i not write correct May 23 16:53:25 m_billybob: de rien! May 23 16:53:33 new age in compilers i guess . . .where the compiler knows the options and paths better than *you* do lol May 23 16:53:59 m_billybob: it's not the compiler that knows this stuff, but the build environment is set up by people who (hopefully) know it May 23 16:54:03 this is going ot make me lazy May 23 16:54:15 m_billybob: if you mess with it, you are certain to mess up royaly May 23 16:54:37 well some settigns like mtune seem obvious but yes, i see your point May 23 16:54:48 tons and tons of options May 23 16:56:12 is it possible to flash internal emmc via fastboot mode of u-boot,? May 23 16:56:23 * m_billybob has no idea May 23 16:56:52 well take that back i think so, but dont know how, and not 100% sure May 23 16:57:07 more of "tons and tons of options" May 23 16:57:48 would most definately involve uEnv.txt im thinking May 23 16:57:59 ok. tnx. then another q. is it possible to get miniUSB working in u-boot? May 23 16:58:05 the 21st century: the age where humankind learns how to handle more and more complex systems until they blow up in the singularity May 23 16:59:20 silentjetty, again another half answer im pretty sure yes, but dont know how and not 100% sure . . . sorry i was just reading on this stuff yesterday evening, and kind of glossed most of it May 23 16:59:29 uenv.txt options are vast May 23 16:59:58 not to mention kernel flag options at boot . .. May 23 17:00:57 actually my primary target is to understand what is done in uboot for am335x family boards May 23 17:01:43 silentjetty, potentially lots and lots from what ive been reading May 23 17:02:12 can set many many things from uEnv.txt apparently May 23 17:02:52 hi all.. May 23 17:02:56 how would the compiler pick up the right cpu if he is cross compiling KotH ? May 23 17:03:11 Rickta59: depends on the compiler May 23 17:03:25 Rickta59: most compilers are written to do just one architecture May 23 17:03:33 Linaro on windows ( x64) May 23 17:03:44 Rickta59: and then there is usually an option ot set the subarch (-march for gcc) May 23 17:04:12 yeah i think that is what he was looking for so he could compile on windows and deploy on debian BBB May 23 17:04:19 Rickta59: that's why your compiler is prefixed with arm-eabi- or something similar May 23 17:04:54 you do not want to do embedded linux development on a windows machine May 23 17:05:06 unless you have a severe condition of masochism May 23 17:05:06 i think he does May 23 17:05:10 known issues ? May 23 17:05:26 it's major pain in the ass to get it working correctly May 23 17:05:33 i would prefer to yes, but if its going ot be a problem . . . May 23 17:05:47 oh well pitas never stopped me before hehehe May 23 17:05:56 use virtualbox, install a simple linux in a VM and live happily ever after May 23 17:05:58 * m_billybob is a pita himself sometimes May 23 17:06:10 which explains the usage of windows right there May 23 17:06:14 i have a dedicated debian build envoirnment May 23 17:06:23 with the same exact toolchain on it May 23 17:06:30 so on linux you still have to supply the right args to cross compile in linux May 23 17:07:01 Rickta59: i think you want to buy a copy of the embedded linux primer May 23 17:07:09 Rickta59: it explains most of your questions in detail May 23 17:07:31 it has a been a while for me and when i was doign this before it was still x86 May 23 17:07:36 KotH, andyhow im not questioning you just to question, i would just like to know, because currenty i dont know . . . May 23 17:07:49 Rickta59: but be aware that the book is a bit dated and for a few things there are easier solutions May 23 17:07:56 Rickta59: but the basics are still the same May 23 17:08:06 m_billybob: try it May 23 17:08:22 KotH, ah ha i have that exact book already in deadtree format May 23 17:08:27 m_billybob: getting a build env running on a linux is a thing of an hour, at most May 23 17:08:32 m_billybob: on windows... i have no idea May 23 17:08:43 so where am i confused May 23 17:08:58 Rickta59: usually, people are confused in their heads May 23 17:09:08 i'm looking at what the angstron build scripts are doing and they supply a shit load of args to make it setup for the beaglebone May 23 17:09:12 KotH, ah well so far i have a minimal file compiling with linaro +code::blocks, with some help from rick May 23 17:09:32 no errors or warning. not going ot bet its optimal though May 23 17:09:40 KotH: actually, confirming with some arm experts here- jumps to upto 2-byte aligned addresses should be possible May 23 17:09:51 you are telling him the "build environment" is going take care of it for him May 23 17:09:54 I will get into debug mode in a bit though to confirm what the linker is doing May 23 17:09:56 Rickta59: the angström buildsystem is probably not the first one you should have a look at if you are not knowledgable about crosscompiling May 23 17:10:08 he is just invoking the cross compiler from teh command line May 23 17:10:30 joel_: in the case of thumb instructions yes, you cannot jump to anything that is not 2byte aligned May 23 17:10:43 joel_: if you have arm instructions, they have to be 4byte aligned May 23 17:10:52 joel_: for details, see the ARM ARM May 23 17:10:55 KotH: so we're talking about -mthumb here, which is THUMB-2 May 23 17:11:18 joel_: wasnt -mthumb thumb1? May 23 17:11:35 joel_: or does gcc select the right thumb based on -march? May 23 17:12:04 joel_: easiest way to check is: do an objdump of your binary and look at the addresses May 23 17:12:21 joel_: both at the destination and encoded in the jump instruction May 23 17:12:27 joel_: no need for a debugger May 23 17:12:48 KotH: the generated disassembly is mixed (16/32-bit) with -mthumb May 23 17:12:50 so its THUMB-2 May 23 17:13:06 joel_: hö? May 23 17:13:13 ah.. May 23 17:13:53 KotH: yes, that'll work before stepping May 23 17:13:58 which reminds me... i've never finished reading the ARM ARM... May 23 17:15:36 KotH: I forgot most of the parts I did read. May 23 17:16:27 georgem: try tai ginseng May 23 17:16:52 georgem: with the power of the two hearts! May 23 17:17:07 anyone know how to mount the SD card for storage on the BBB? May 23 17:17:11 i can't tell what device it is May 23 17:17:35 probably mmc1 May 23 17:17:44 i only see mmc0* in /dev May 23 17:17:49 not sure why it's not showing up May 23 17:18:50 cmicali: I dont actually have one, but let me look at the device tree file. I had it open a second ago May 23 17:19:06 cmicali: mmc0* is your sd card May 23 17:19:30 KotH: it's not the eMMC? May 23 17:20:04 yeah. according to the device tree the card is first and the eMMC is second May 23 17:22:58 It probably is if you don't have working card inserted. *shrug* May 23 17:23:17 cmicali: linux starts to number things from the first device that is detected May 23 17:23:38 cmicali: if you have nothing in the first slot, there is nothing to detect there May 23 17:23:52 cmicali: and: if in doubt, check dmesg May 23 17:23:56 KotH: oh do you have to have the card in at boot for it to be detected May 23 17:24:07 uff... May 23 17:24:16 :) thx May 23 17:24:19 somebody mentioned something about this some days ago May 23 17:24:22 it might be May 23 17:24:23 i dont know May 23 17:24:31 pretty sure it does May 23 17:24:37 looking in dmesg, mmcblk0 is the emmc May 23 17:24:48 * KotH points in the general direction of panto, koen, av500 and all the other experts May 23 17:25:19 do you see any dmesg activity if you insert/remove the card? May 23 17:25:27 no May 23 17:25:40 yes you have to have the sdcard at boot inserted May 23 17:25:48 the card insertion detection doesn't work yet May 23 17:25:51 panto: thx May 23 17:25:52 ah ok May 23 17:26:01 panto: broken in the kernel or the hardware? May 23 17:26:01 panto: isn't there a gpio for that? May 23 17:26:05 no May 23 17:26:08 or did someone eff the muxing? May 23 17:26:10 I was going to suggest maybe your sd card was actually a tortilla chip May 23 17:26:18 supposedly you can do it with a standard mechanism May 23 17:26:22 georgem i thought those were supported May 23 17:26:24 but, take a wild guess May 23 17:26:33 :) May 23 17:27:05 well the only way i knew off was a card detect line connected to a gpio May 23 17:29:27 georgem: tortilla chips mmmm May 23 17:33:07 another way is polling May 23 17:33:46 joel_: yeah, theres a pin for that May 23 17:34:41 mdp: yes! true! May 23 17:37:15 KotH: turns out the assembler was being in ARM mode as it didn't have .thumb May 23 17:37:27 .thumb too wasn't an option because certain instructions couldn't be encoded in thumb May 23 17:38:02 so all the ARM instructions in the assembly fell on a non-4byte boundary, caushing the jump to it from THUMB-2 code to die May 23 17:38:31 so the fix is ".align 2" :-) May 23 17:39:11 ideally though if everything was C code, then -mthumb-interwork would've worked May 23 17:39:12 Is it beer 30 yet? I'm bored of sitting around waiting for hardware engineers. May 23 17:40:33 panto thx i got it working May 23 17:41:03 had to be in at boot and have uenv.txt that booted from emmc May 23 17:41:08 right May 23 17:49:23 I've been brainstorming ideas for beaglebone projects I could do with my kids. Would be fun to stick a beaglebone and CAM on an RC car. Battery cape is pretty expensive though... May 23 17:49:43 georgem: two words.. spy drone May 23 17:49:58 mranostay: I know.... I want to make one so bad May 23 17:51:10 Unfortunately I've looked at quite a bit of the different things people have done on diydrone and that stuff gets expensive. May 23 17:53:33 Someone needs to start a website with awesome electronics salvage tips. For instance if there was a certain toy you could buy for under $20 that had battery pack and regulated 5v supply you could easily re-purpose, that would be good to know. May 23 17:59:45 so . . . #include int main(){return 0;} . . .

My long running saga of not being able to build the release kernel I think has come to an end. IT's currently building the root_fs :D May 23 18:05:08 Spirilis, also just remembered im compiling in debug information too so yeah May 23 18:05:09 So how do I turn that into a build that can be blown into the board flash? Haven't seen instructions to do that anywhere May 23 18:05:49 Spirilis, and yeah, used to mspgcc, where everythign would be 8-9 times smaller lol May 23 18:06:47 KotH, probably one of the documents that "ships" with the linaro toolchain May 23 18:07:11 lots to read . . . May 23 18:09:00 m_billybob: the linaro toolchain is nothing else but gcc+binutils nicely packaged May 23 18:09:12 <_av500_> and made faster May 23 18:09:18 <_av500_> with fast_memcpy May 23 18:09:20 m_billybob: maybe here and there a few modifications for better handling of arm May 23 18:09:36 readelf is your friend May 23 18:09:40 _av500_: did they wax the bits? May 23 18:09:42 _av500_: fast_memcpy? that sounds like the mplayer fast_memcpy... which used to be faster...10y ago May 23 18:10:20 m_billybob: for more questions about how the linaro toolchain differs from stock gcc/binutils, ask our local expert mru :) May 23 18:10:59 linaro toolchains are nothing but vanilla+backports May 23 18:11:26 <_av500_> stock vanilla? May 23 18:11:30 _av500_: nice security :) May 23 18:11:48 _av500_: vanille ist eine pflance, die als kleine "stöcke" verkauft wird ;) May 23 18:12:08 all toolchain work is done against upstream master May 23 18:12:29 Whooohooo cloud9-gnome-image is built :D May 23 18:13:02 <_av500_> I feel a distrubance in the farce May 23 18:13:21 PeteS: can you answerme one question: what is cloud9? all i can find is an idea... which i doubt you are running on the bbb May 23 18:13:24 <_av500_> as if millions of make jobs cried out and exited May 23 18:14:15 KotH: no idea lol just its in the standard build May 23 18:14:31 ^^' May 23 18:14:37 * KotH will die stupid May 23 18:14:52 KotH, well in comparrison to mspgcc, is mostly the same, but the include path structure seems radically different. Eventually though in time, i'll figure all this stuff out. I've been programming as a hobby since the 90's but only recently, as in the last 6 or so months got serious into understanding toochain stuff May 23 18:15:09 <_av500_> cloud9 is a paradigm shift May 23 18:15:19 <_av500_> going forward May 23 18:15:40 _av500_: what is it and what does it do? May 23 18:15:46 _av500_: and which cloud9 is it? May 23 18:16:03 <_av500_> its agile May 23 18:16:51 anyone know how to build the dmmc-flasher package? May 23 18:17:00 <_av500_> the DMV? May 23 18:17:03 Want to upgrade my board now :D May 23 18:17:10 So far settign up under widnows seems fairly painless. the include path through me off for a while though May 23 18:17:19 emmc-flasher even May 23 18:17:20 windows too May 23 18:17:32 <_av500_> PeteS: no idea May 23 18:17:40 <_av500_> koen might know May 23 18:17:40 me either May 23 18:18:11 yeah hopefully he'll be on to give instructions later May 23 18:22:01 <_av500_> you also just take the existing flasher card and change the payload May 23 18:22:05 <_av500_> maybe May 23 18:22:12 <_av500_> see emmc.sh May 23 18:23:05 _av500_: well.. software development got so agile, that the old chaps cannot keep up anymore and is filled with teenagers that are too full of themselves May 23 18:23:52 <_av500_> its time to disrupt that May 23 18:24:07 * mdp senses a coming disruptor beam May 23 18:24:23 something that will let old people keep up with youngsters in s/w?!? May 23 18:24:24 _av500_: what are you going to do? May 23 18:24:30 * mdp braces himself May 23 18:24:34 _av500_: senioren turnen für ausgediente programmierer? ;) May 23 18:24:41 <_av500_> yep May 23 18:24:44 <_av500_> or gardening May 23 18:24:50 <_av500_> using 3d printer robots May 23 18:24:54 <_av500_> printed May 23 18:25:17 will you print s/w developers? May 23 18:25:40 <_av500_> damn, they want to lower the DUI levels for biking here May 23 18:25:56 <_av500_> I hope crawling will stay unrestricted May 23 18:26:34 we have restricted crawling May 23 18:26:40 they should raise the levels! May 23 18:26:50 the police blotter is filled with the crawling arrests weekly May 23 18:26:55 at some point, all those trunkards would die out :) May 23 18:29:03 <_av500_> nah May 23 18:29:05 Or just learn how to roll with the flow. May 23 18:29:34 <_av500_> I only drink at work May 23 18:29:38 <_av500_> but then I need to get home May 23 18:29:43 wonderful thing about being a hobbyist programmer. you get to learn what *you* want to learn. :) May 23 18:30:17 m_billybob: wonderful thing about being a hobbyist programmer. you get to learn something. May 23 18:30:20 no deadlines, no early morning showers with caffine soap, assuming you do gt some sleep May 23 18:31:37 * m_billybob nods May 23 18:32:17 and if you dont fel like "rogrammer gymnastics" its not required ;) May 23 18:32:33 programmer gymnastics? May 23 18:32:39 feel like " programmer gymnastic" but yeah May 23 18:32:40 c'est quoi ça? May 23 18:32:46 heh May 23 18:33:07 greetings mrpackethead May 23 18:33:17 mrpackethead: how may we JIHAD you today? May 23 18:33:21 * m_billybob doesnt speak fresh May 23 18:33:30 french . . . May 23 18:33:34 m_billybob: what does programmer gymnastics mean? May 23 18:33:36 apparently i dotn speak english either. May 23 18:33:56 * KotH speaks only his own dialect of swiss german May 23 18:34:17 KotH, i dont know spotted some german in chat above, my german is rusty, and conetext off too possibly May 23 18:34:52 m_billybob: swiss german is not german... most germans dont understand the swiss May 23 18:34:53 exercise for senior programmers possibly ? May 23 18:35:02 nor dutch May 23 18:35:16 well dutch is easy... if you know swiss german and english :) May 23 18:36:32 I lived in germany ( as a soldier ) during the 80's for 3 years, i should probably know more german. . . May 23 18:36:47 * KotH has never seen anything that would resemble exercises for senior programmers May 23 18:37:34 KotH then as you said swiss german doesnt translate well May 23 18:37:57 but then, at most companies i worked for, i was one of the more knowledgable programmers... and that says more about the skill of the other programmers than mine ^^; May 23 18:39:46 m_billybob: or type it May 23 18:40:09 a chum etz! schwyzerdütsch is tammi eifach zum schriibe May 23 18:40:32 <_av500_> +1 May 23 18:41:01 Can anyone help? Step 1 and 2 ok. Step 3 does not show green header on 192.168.7.2 page. Is it connected? Browser problem? Using Firefox. BeagleBone Black with 5-13 image. May 23 18:41:28 Nexas: whcih exact steps were you following? May 23 18:41:55 soudns like getting started instructions but green headers ? huh ? May 23 18:42:49 Nexas, oh i grok now yeah try chrome May 23 18:43:07 On the getting started page. Install drivers, update image, etc. Result is that sample code does not seem to run and cant login to unit. I am on USB connection. LEDs just flicker. I have 2 boards that both behave same way so I'm guessing its a browser issue, but what? May 23 18:43:14 Nexas, oh i grok now yeah try chrome May 23 18:45:17 Nexas, for what its worth between my buddy and I we have two bbb's neither one worled well with firefox on the gettign started web page stuff May 23 18:45:32 worked* May 23 18:45:43 Chrome seems to work a treat May 23 18:48:10 Ok. Chrome works. Maybe the BbB folks cold update that warning in the startup instructions to say that FireFox wont work either. Thank you for your help!! You guys are totally amazing! May 23 18:51:46 Does connman cache old networking info somewhere? Because it's not obeying my interfaces file on connman start. May 23 18:51:48 Nexas, yeah i took those instructions to mean use either of the two that work, but my defauklt browser is Chrome, where my buddies is firefox . . May 23 18:54:32 fiola, possibly related, if you mean from within X, the gnome app seems to keep its own information under the advanced tab i think ? But i noticed that too a while back on LMDE interfaces file wasnt cooperating. May 23 18:56:37 m_billybob: not in X, I just have a serial connection into BBB (standalone) and am trying to set it up like I set up my BB white. I remember connman being a pain back then as well, but it did obey interfaces. On BBB it's doing its own thing, like if it were squirreling old config away somewhere. May 23 18:59:53 m_billybob: for example, it's setting a 169.254.... address on eth0, when I don't have any such address set in interfaces and am not using DHCP but static. It's sort of doing its own thing. May 23 19:00:53 should it be possible to boot a mainline kernel on a Beaglebone rev A6? apparently as of Oct 2012 it wasn't, trying to find out if this has changed May 23 19:00:54 is connman active? May 23 19:00:55 KotH: good morning. May 23 19:01:21 And it's setting a nonsense default route, without a via gateway. So, not surprisingly, it ain;'t working :P May 23 19:01:58 fiola, ok yeah not sure . . . almost seems as though you're not aquirering the IP you request as static ip May 23 19:01:58 fiola: m_billybob, which build are you guys using? May 23 19:02:04 thurgood: connmand is running, yes May 23 19:02:25 mrpackethead if you mean on the bbb im using same setup you got workign last night May 23 19:02:27 debian May 23 19:02:34 right. May 23 19:02:53 mrpackethead: default, BBB arrived yesterday and it's exactly as it arrived. May 23 19:02:55 i had zero problems with the networking. May 23 19:03:39 mrpackethead yeah like we talked about before i have no idea *why* i have to set nameserver to my gateway adress, but i just do, and this is not the first time ive had to do the same May 23 19:04:14 m_billybob: my bbb, was correctly setting its name server, default gateway etc etc May 23 19:04:17 so now its like a kne jerk reaction i just go into resolve.conf and change nameserver to what i want it to point to May 23 19:04:20 all from the dhcp request May 23 19:04:34 there was no need to change anything May 23 19:04:53 thats why you get paid the big bucks, and im just a networkign flunky lol May 23 19:05:22 BBB was setting itself up fine over the usb0 link, but this is the standalone configuration now, not using the USB lead, it's not even plugged in. May 23 19:05:55 perhaps mrpackethead knows whats up May 23 19:06:33 fiola only thing i can think of off the top of my head is that perhaps uEnv/txt has teh IP{ hard coded ? *shrug* May 23 19:06:46 And additionally all mention of interfaces other than lo and eth0 is commented out in /etc/network/interfaces. So, really, there should be nothing "clever" going on. Pure static config, simple. May 23 19:06:47 eEnv.txt* May 23 19:06:56 Ew May 23 19:07:05 uEnv.txt bah May 23 19:08:17 Certainly could be that. After all, that part has changed since BB white days. May 23 19:09:07 It would explain why its setting a daft default route too, without a via gateway. May 23 19:09:33 there was no need to change anything/ May 23 19:09:37 fiola: your using the angstrom distro that shipped with the BBB May 23 19:09:43 Yeah May 23 19:10:21 i dont' ahve much confidnece in what has shipped May 23 19:10:41 the first ones i got you coud'nt even ssh into May 23 19:10:56 it seems it still needs a lot of work May 23 19:11:10 understaffed May 23 19:11:47 I know that in theory there wasn't any need to change anything in order to run standalone (just change IP, gateway, etc), but I started commenting stuff out when it didn't work as expected, simply to eliminate variables. Once it works standalone I'll put all the commented-out stuff back. May 23 19:12:00 what was that ip again fiola ? 162.* ? if memory serves that a default interface IP if it cant pick up a router May 23 19:12:49 169.254.10.175/16 --- not an address I've ever used anywhere. May 23 19:13:44 well i dotn know the correct technical term, but say on windows ( not sure about linux) if you dont configure an interface at all you get a the interface will take a similar IP by default May 23 19:14:25 err the interface will take a similar IP by default -a May 23 19:14:47 typically on windows when there is no ethernet cable plugged in May 23 19:16:21 fiola what is teh bbb plugged into ? directly to a computer, or on a network with a router ? is the cable known good ? May 23 19:16:38 Maybe I should zap connman and just put a manual network config script in. It's easy, dunno why connman is making it hard. May 23 19:18:52 ah i missed some of what you said above. ok, yeah im off track May 23 19:18:57 serial cable. May 23 19:20:00 m_billybob: It's a big complicated network, but the details shouldn't matter. The gateway is certainly reachable from the switch that BBB is connected to. In fact it's the same switch as the BB white is using right now. May 23 19:20:38 And the white works. I powered it up to see how I'd configured interfaces for connman. May 23 19:20:58 the usb interface worked fine though you say eh ? May 23 19:21:10 seems odd. May 23 19:21:29 Yep. The "out of the box" experience just by plugging in BBB via USB was perfect. May 23 19:21:49 Standalone ain't :P May 23 19:22:28 wonder if it would change if you reverted to usb power again May 23 19:22:51 Nah, USB not plugged in anymore, it's on barrel connector. May 23 19:23:54 well ive read some posts on the groups whee people have had issues using the 5v barrel input, but usualy its using an improper power supply May 23 19:24:02 just thinking outloud . . . May 23 19:24:34 This one's a good one, 5.00V open circuit and 4.97V when connected. May 23 19:28:52 I'll comment everything back in and plug in the USB lead. Perhaps a sensible default route will appear. May 23 19:30:04 yeah let us know what you find the cause to be, soundslike an interresting problem to solve May 23 19:30:25 i mean from here outside lookign in it almost soudns like a faulty ethernet cable May 23 19:30:40 but if eth0 worked with usb power yeah no idea what that could be May 23 19:30:48 other than a possible rma issue May 23 19:31:16 Well I can eliminate that possibility by swapping the white's and black's cables, one sec. May 23 19:31:27 m_billybob: you'll get a 169.x.x.x addres if dhcp fails May 23 19:31:39 if the ethernet is down, you'll not get any address May 23 19:32:32 ah ok May 23 19:33:18 the .x.x.x bit gets derivced from the devices mac address May 23 19:33:34 and id have to assume that fiola is smarter tha nthe average bear, and knows how to set up the gateway ip May 23 19:34:23 * m_billybob scratched head May 23 19:34:30 scratches too but lol May 23 19:36:46 Hehe. Well I think I know how to set up an IP gateway. It would be problematic if a network engineer couldn't do that. :P May 23 19:37:10 fiola: i've seen such ^^' May 23 19:38:05 Hehe. Aye, some 9-to-5ers with a formal job title are a joke. May 23 19:38:36 most 9-to-5ers are a joke May 23 19:39:04 Usually just front line staff though. In their defence, they don't paid much either. May 23 19:39:28 ok.. i have very little dealings with front line staff... May 23 19:40:02 KotH: You may have gained an extra year of life :P May 23 19:40:03 none of the companies i worked for, or any of our customers has sales shops or anything resembling helldesk May 23 19:40:40 fiola: being an engineer in a company where deadlines are always very tight isn't healthy either ^^' May 23 19:42:16 fiola, oh well id hope so ! lol May 23 19:42:20 yeah you know then. May 23 19:43:40 KotH: It's possible that these "insights" are just a worm's eye view, and that the real big picture is "Working is bad for your health". :P May 23 19:43:57 hehe May 23 19:44:01 working for *others* is bad for your health. May 23 19:44:22 fiola: i'm still looking for a patron who pays my bills so i can do what i really want to... but these people are hard to come by ;) May 23 19:48:09 dhcp is your freind or your enemy May 23 19:48:10 :-) May 23 19:48:57 KotH: have you done much FPGA stuff? May 23 19:49:20 mrpackethead: nope May 23 19:49:34 Is Koen about yet? May 23 19:49:35 mrpackethead: only my masterthesis and some odd projects afterwards May 23 19:49:40 along the lines of 9 to 5ers . . . I remember back in the 90's studying for A+ certs, wonderingwtf a motola 68000 had to do with modern PCs . . . some of the questions in those exams are well pretty stupid. May 23 19:49:45 mrpackethead: why? May 23 19:49:57 KotH: so just a bit more than most May 23 19:50:31 mrpackethead: well.. if you mean the average electronics designer, then probably...but i'm by far not an expert in fpgas May 23 19:51:04 KotH: my student engineer will be doign a coupel of papers on them next semister, and for his "his choice" project at work, we're doing some FGPA stuff May 23 19:51:09 verilog is so much fun, it feels like you are actually building things May 23 19:51:28 i'm just wanting to get enough info in my head to be typically dangerous May 23 19:51:29 c is more like writing a book May 23 19:51:33 Well DHCP has its place, but if static config has a problem then DHCP isn't going to work either. Static is the fundamental one, and DHCP is just there to make ordinary people's lives easier. May 23 19:51:46 Russ: verilog is imho an abomination that should never have seen the light of the world! May 23 19:51:51 hooray! May 23 19:51:58 that only makes it more awesome May 23 19:52:00 fiola workign yet ? May 23 19:52:00 Russ: vhdl is much much nicer May 23 19:52:16 mrpackethead: what do you want to know? May 23 19:52:16 * Russ continues to code from the book of the damned May 23 19:52:22 vhdl... May 23 19:52:26 not sure yet May 23 19:52:35 try system generator :D May 23 19:53:09 mrpackethead: if you have specific demands on the fpga for the application, select first the fpga by the publsihed specs May 23 19:53:23 no application yet May 23 19:53:30 mrpackethead: if you dont have specific demands, select the one that you have most people around that know it and its tools May 23 19:53:48 its a technology that i just think looks (a) interesting and (b) persavive May 23 19:53:56 mrpackethead: if you want to rely on free tools (like ise web edition) choose the fpga accoridngly May 23 19:54:27 mrpackethead: the only thing you have to keep an eye on with fpga designs are the HF characteristics. May 23 19:54:57 mrpackethead: ie power supply and ground must be designed for very high frequency operation, even if you have a slow clock May 23 19:55:02 yeah, even with our microproessor stuff these days, thats certianly a consideration May 23 19:55:18 i read this -> http://www.taylorkillian.com/2013/04/using-fpga-of-eecolor-color3.html May 23 19:55:19 i guess it just gets faster and harder May 23 19:55:20 fpgas are worse than modern cortex-a's in that regard May 23 19:55:21 much worse May 23 19:55:28 picked one of those up for a "cheap" dev board May 23 19:55:55 KotH: i'm got a small pile of FPGA cape pcbs made May 23 19:56:13 mrpackethead: if your student knows already vhdl or verilog, choose that language... if he knows neither, choose vhdl and get him 2 May 23 19:56:23 mrpackethead: if your student knows already vhdl or verilog, choose that language... if he knows neither, choose vhdl and get him "the desginers guide to vhdl" by ashenden May 23 19:56:34 bah May 23 19:56:34 mrpackethead: best book on vlsi design i've ever seen May 23 19:56:44 KotH, i take it you've some experience with FPGAs then ? May 23 19:57:02 m_billybob: read how this discussion started :) May 23 19:57:02 m_billybob: KotH is very understated sometimes May 23 19:57:06 if you have extensive experience is ada, choose vhdl May 23 19:57:16 if you have extensive experience in c, choose verilog May 23 19:57:24 Russ: depends... May 23 19:57:37 https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-ash4/460990_10151622213382661_1846566414_o.jpg May 23 19:57:53 Russ: most people i say that vhdl is easier to understand than verilog May 23 19:58:02 at least my ada experience comes in handy for something, being able to comprehend vhdl May 23 19:58:13 Russ: beside, verilog makes it very easy to do certain mistakes, much more than c... which are fucking damn hard to spot May 23 19:58:15 http://ebrombaugh.studionebula.com/embedded/bcc/index.html May 23 19:58:21 m_billybob: BB white works fine with both LAN cables, so it wasn't that. It was a long shot anyway, the only thing that matters to BB is that there's a live physical layer at the other end so that the interface doesn't drop. May 23 19:58:40 Russ: vhdl makes it very hard to make syntactic mistakes by its overredundand way of typing May 23 19:58:49 fiola, hmm stumper, which makes the problem even more interresting ;) May 23 19:58:53 yes, you have to type everything several times May 23 19:58:59 KotH: thats what i'll be messing with anyway. May 23 19:59:15 fiola, maybe a reflash will clear thigns up if all else fails May 23 19:59:33 low cost entry level May 23 19:59:57 mrpackethead: hmm? why a spartan3? May 23 20:00:05 becuase it was avaialble May 23 20:00:08 mrpackethead: are the entry level spartan6 more expensive? May 23 20:00:13 not sure May 23 20:00:44 its a good starting point May 23 20:00:50 mrpackethead: i'm missing buffer capacitors in the pictures :) May 23 20:01:19 there are parts on the back May 23 20:01:26 they shouldnt be May 23 20:01:33 well done on a clean layout May 23 20:01:36 if possible, move them to the frontside in the next revision May 23 20:01:45 i did'nt do the design May 23 20:01:54 the additional 1.6mm makes a lot of difference in impedance May 23 20:02:00 this is a known working system May 23 20:02:01 too many people just throw components at the board May 23 20:02:10 * KotH nods May 23 20:02:19 there are 10 or so in exisitance May 23 20:02:47 theres another cape proejct out there May 23 20:02:50 the logi-boine May 23 20:02:54 that uses a Spartan 6 May 23 20:03:07 but it seems like the design is still unstable May 23 20:03:07 the one mranostay is talking about? May 23 20:03:24 mrpackethead: design doesnt look bad, no obvious mistakes May 23 20:03:36 we'll find out then1 May 23 20:03:43 and its really only a learning exercise May 23 20:03:51 mrpackethead: though' as i said, would move the 100n capacitors to the front side for lower inductance May 23 20:04:00 yes. May 23 20:04:21 http://valentfx.com/prj/fpga-dev/19-logi-bone-cape May 23 20:04:39 mrpackethead: and i would change the 10u tantal caps at the LDOs to 10u X5R/X7R, if the LDOs are still stable with the low ESR May 23 20:04:59 yup me too May 23 20:05:14 i try to avoid the use of Tant's in general May 23 20:05:19 its against my religion May 23 20:05:26 lol May 23 20:05:44 tantulum is so evilly mined May 23 20:06:01 i dot' knowngly want child labour! May 23 20:06:03 yes, but it has many advantages compared to ceramic capacitors May 23 20:06:10 yes, it does. May 23 20:06:15 and sometimes, there is no other way May 23 20:06:32 esp, if you need > 10uF May 23 20:06:33 * KotH had a project where they needed 0402 sized 47u capacitors May 23 20:06:46 at 100V probably May 23 20:06:55 uhmm.. ceramics are available to a least 100u@6.3V May 23 20:07:03 at 100V, you dont want tantal ;) May 23 20:07:12 yes, indeed ceramincs are May 23 20:07:16 they go quite big May 23 20:07:26 1206 or so May 23 20:07:30 but the $$$$ and space is proporitional. May 23 20:07:32 maybe even 0805 these days May 23 20:07:44 yeah May 23 20:07:49 i have some 2nf(?) 2000V certamics on a board i'm using May 23 20:07:51 high valued cer caps are expensive... May 23 20:07:58 they are 1206 May 23 20:08:18 sorry, they are 1nf May 23 20:08:30 * KotH has used such caps as well May 23 20:08:41 ethernet May 23 20:08:46 :-) May 23 20:08:59 building a micro sized CFL electronic for a customer May 23 20:09:15 center taps of the eternet transfoerms are connected to ground via a 75R and the 1000pf cap May 23 20:09:29 that was a fun thing to do until we figured out why our chips are blwoing up :) May 23 20:09:59 75R? not 75k? May 23 20:10:27 hi, what's the latest kernel (that supports SGX driver) for beagleboard xM? May 23 20:11:01 can i use mainline? May 23 20:11:08 * KotH wonders whether ther is anything else to mention about fpgas May 23 20:11:15 ping jkridner_ May 23 20:11:26 For FPGAs you need lots and lots of patience.. May 23 20:11:36 Defiant: why? May 23 20:11:43 I'm working on getting back into fpgas now May 23 20:11:50 KotH: One for the tools, one for the synthesis time May 23 20:11:50 Defiant, you just need lots of testbenches May 23 20:11:51 l8r May 23 20:11:54 gotta go to work May 23 20:11:59 I worked with them some back in 2000-2001, and I'm trying to install the stupid tools again now May 23 20:12:06 mrpackethead: oh.. very important thing: you can kill fpgas with the wrong firmware May 23 20:12:20 damn.. May 23 20:12:25 KotH, killed one before? May 23 20:12:31 why cant people leave ther irc clients on May 23 20:12:45 Russ: not an fpga... but a lot of other stuff :) May 23 20:13:28 Defiant: you have never done development on a multi-million lines project May 23 20:13:42 Defiant: compilation time... somewhere around a day :) May 23 20:14:06 Defiant: but yes, fpga tools generally suck May 23 20:14:09 all of them May 23 20:14:29 KotH: so Alteras are not better? (only used xilinx) May 23 20:14:51 havent worked with quartus yet May 23 20:15:00 but i dont expect much of it May 23 20:15:06 KotH: You should never synthesize something that doesn't work in simulation. Your just wasting time (my opinion after 4 years of working with them.) May 23 20:15:33 spenser309: that goes w/o saying May 23 20:15:47 KotH: if it works in simulation it generally works in production (except for external interfaces) May 23 20:16:13 spenser309: external interface matters...that's where the magic smoke waits to be released of its confinement May 23 20:16:27 what do you guys do with them? May 23 20:16:36 anyways.. time to sleep May 23 20:16:40 good night boys, girls and trolls May 23 20:16:42 I've got a couple cheapy dev boards, and I've just messed around with silly things May 23 20:16:58 back in the day when i was plying with them, I made one into a color serial terminal :P May 23 20:17:02 I seem to be having a problem booting with an empty microSD card in my BeagleBone Black. It's a genuine 16GB SDHC card (checked with h2testw), but when I put it in the BeagleBone and apply power, instead of booting from the internal memory it seems to hang during boot. USR0 through to USR2 light up, but USR3 does not. May 23 20:17:12 Does anyone have any ideas as to what might be wrong? May 23 20:17:17 ssi. http://ebrombaugh.studionebula.com/embedded/bcc/index.html May 23 20:17:29 we have some pcbs avaialbel if you are interesing May 23 20:17:33 inerested May 23 20:17:42 very nice May 23 20:17:48 $14 May 23 20:17:50 for a pcb May 23 20:17:54 I'd be willing to do that May 23 20:18:04 i made up 50 May 23 20:18:04 what's the cost to populate it roughly? May 23 20:18:09 ~$25 May 23 20:18:12 not bad May 23 20:18:20 those wee little 200k chips are cheap May 23 20:18:42 i bought enough bits from DK for 10 boards for about $180 May 23 20:18:47 but i had some bits already May 23 20:18:57 KotH: it's not quite that easy. As long as you specify the correct IOB parameters its very difficult. May 23 20:19:24 ssi, are you US based? May 23 20:19:28 yeah, atlanta May 23 20:19:28 or elsehere? May 23 20:19:40 $14 + $4 for freight May 23 20:19:48 can you ship 2 for $4? :D May 23 20:19:53 or $60 for 5 May 23 20:20:00 yes can May 23 20:20:09 anyone know where to get the latest kernel for a beagleboard xM ? May 23 20:25:21 I guess circuitco needs to do some better documentation, or something. May 23 20:25:41 people keep comming in with the same simple problems and no ones bothered to document it yet May 23 20:26:41 "simple" as in common, and easily fixable *if* you know the secrete magic hand waving technique May 23 20:26:57 Is Circuitco's wiki open? May 23 20:27:05 m_billybob: It's not just circuitco, I think. The BeagleBone Black SRM A5.2 diagram on page 27 seems to mix up the BOOT and RESET buttons. May 23 20:27:14 As far as I can tell. May 23 20:27:36 Sophira, you're problem is uEnv.txt must exist on the sd card with the proer parameters in it May 23 20:27:44 proper* May 23 20:27:50 m_billybob: Even though I'm not trying to boot from the SD card? May 23 20:28:07 the proper parameters are on the google groups, somewhere i beleive and yes May 23 20:28:16 its a uboot "thing" May 23 20:28:17 Sophira: that's correct. I complained on the forums about it, here's the file BTW: http://spirilis.net/junk/uEnv.txt May 23 20:28:26 (Because according to the SRM, the default is to boot from the internal eMMC. But okay, I'll look those up!) May 23 20:28:29 try to d/l that directly and copy it over, it must not have CR (carriage-return) characters in it May 23 20:28:42 * Sophira uses wget. May 23 20:29:08 Spirilis, for what its worth, that can be compile out of uboot or so ive read May 23 20:29:18 the debian instructions i followed mentioned somethgin to that effect May 23 20:29:24 m_billybob: figured as such, I'll wait for them to officially axe it...... cause it's a dumb feature IMO May 23 20:29:48 ssi: soory opps May 23 20:30:05 sure you can compile whatever environment variables you want into uboot May 23 20:30:28 Spirilis, cant say i disagree, though having it as an options could be a goood thing May 23 20:30:44 for say TFTP booting etc May 23 20:31:14 I'm not a Windows user, but seriously, how hard would it be to make uboot ignore CR so that there are fewer support calls? A win for everybody. May 23 20:31:20 but idk somethign like uboot -env-path= . . . ? May 23 20:31:31 lol yeah May 23 20:32:15 fiola several windows text editors have an option to use unix file formating May 23 20:32:40 most people seem unaware of its existance and if they do know of it they dont know how to use it May 23 20:32:50 Yeah, but that's not the point. It's much easier to strip CRs than it is to document the need for their absence. May 23 20:32:55 Spirilis: Thanks, that file worked brilliantly. May 23 20:33:21 And yeah, agreed. May 23 20:33:41 or just act less like python and worry only about arguements and not indentation ? May 23 20:33:45 lol *shrug* May 23 20:33:46 np May 23 20:34:09 indentation formating whatever . .. May 23 20:36:08 There's a wise saying something like "Be generous in the formats you accept, but exacting in those you send." Uboot could do with some wisdom :P May 23 20:36:50 And it's just good defensive programming practice anyway. May 23 20:36:59 paches are probably welcome :P May 23 20:37:16 Good idea :P May 23 20:37:55 that's so 80s, we do the opposite now May 23 20:38:02 Hahahaha May 23 20:38:05 fiola: just don't slip on the monkey poo May 23 20:38:32 mru: that was highly dangerous to this coke and the keyboard :P May 23 20:39:49 par for this channel, I'd say May 23 20:40:53 <_av500_> +1 May 23 20:46:27 mru: nice. May 23 20:47:43 ssi: sorry are you here still May 23 20:53:52 what kind of coke? May 23 20:54:15 <_av500_> pure May 23 21:00:47 bolivian May 23 21:17:17 fiola, any joy yet ? May 23 21:21:25 ah best burgers ive made in a while May 23 22:27:12 new to beagle bone black - I can ping yahoo, but the chromium browser doesn't work. very strange any ideas? May 23 22:31:25 newbie07: dns working? May 23 22:31:37 localhost website working? May 23 22:41:41 m_billybob: Sorry, I disabled connman earlier and replaced it with my own quick hack of a start/stop script, using iproute2 directly. Everything worked perfectly. So, it's just connman throwing a spanner in the works somewhere. A usb0 interface appears without me asking for it, so something else is messing with networking too, separate from connman. May 23 22:42:14 Couple of mysteries, but board is fine. May 23 22:48:31 fiola, awesome, and no worries you're not the only one multitasking or are busy, ive been constantly in and out all day today even when we were talkign earlier lol May 23 22:48:55 got company comming this weekend, and spring cleaning is happening right now May 23 22:49:33 Oh you're not doing it right. Spring cleaning is what you invite guests for. :P May 23 22:50:29 fiola, plus i was starting to feel like the kids in the back seat do{are we there yet ?!"}while(!there) May 23 22:51:04 lol wouldnt that be nice lol but actually they're goign ot help us shear sheep ;) May 23 22:51:26 Not really sure what to do about the connman issue, or indeed about Angstrom. Can't see myself fighting every step of the way, so I guess I'll install some full distro, maybe Debian, Arch, or Gentoo. May 23 22:51:52 if you're a network engineer you'd probably feel more at hom with debian May 23 22:52:27 we've been running it on our for the last week or so, and now mypacket is using it perhaps you could get some feedback to go on May 23 22:52:41 i havent really done much with mine yet, but so far . . . its pretty solid May 23 22:53:03 root@arm:/bin# uptime May 23 22:53:03 20:46:31 up 2 days, 3:46, 1 user, load average: 0.00, 0.01, 0.05 May 23 22:53:04 Gentoo is the friendliest on desktops for me, but it requires too much compilation for a lowly Cortex-A8. Although I guess I could cross-build everything. May 23 22:53:18 ah yeah i dont plan on running a desktop personally May 23 22:53:33 there is also supposed to be a sabayon port but dont know how far along that is yet May 23 22:55:19 Oh, I don't plan on any desktops on BBB, except maybe to experience how it survives. I should have said more generally "Gentoo is the friendliest on powerful systems for me". May 23 22:56:00 My interest is in playing with PRUs. That's BBB's fun part :P May 23 22:56:06 gentoo seems right up my alley excep ive never spent time on it, personally been using debian since . . .idk long time May 23 22:56:19 Aye, Debian's fine. May 23 22:56:24 buildroot kinda works for me (except for kernel/bootloader part), but I really needed something minimal to run a single app and that's it May 23 22:57:41 Ive played with Sabayon a little though, supposed to be a "gentler LFS" sort of deal. but i found even though it was supposed to be "cutting edge" it still lacked some of the early adopter hardware support May 23 22:58:01 x86 of course. not embedded yet May 23 22:58:58 I have Sabayon on a laptop. I won't do that again. It's fine in its own right, but rapidly gets messy when you emerge from multiple Gentoo overlays instead of just Sabayon's. May 23 22:59:27 ah May 23 22:59:43 i just toyed aroudn with the liveCD way back when May 23 23:00:07 i like the idea of compiling from sources just for what i want/need May 23 23:00:13 Fun days with BBB. Low investment :-) May 23 23:00:20 yeap May 23 23:01:05 i think its a very good piece of hardware for remote management stuff too May 23 23:01:15 or could be used as such May 23 23:01:25 Quite awesome. Leaves Pi in the dust. May 23 23:01:44 no doubt, except rpi still has the media playback advantage May 23 23:02:00 media is overrated May 23 23:02:09 Media is for consumers. May 23 23:02:12 not really what im personally interrested in though. my laptop plays media just fine May 23 23:03:53 Kinda funny actually that Pi's only hardware advantage is in media, when its purpose was supposedly for education. May 23 23:04:38 well think about it though. how they positioned themselves with the actual hardware. How many exposed gpio's does the rpi have ? like maybe 16 at most ? May 23 23:04:40 I guess they can still teach kids to be obedient little consumer. :P May 23 23:04:43 its purpose was to shift surplus chip stock May 23 23:04:56 You might be right. May 23 23:05:03 ancient ARM11 chips May 23 23:05:32 its a clever ploy May 23 23:05:35 seemed to work May 23 23:06:03 they sold like hotcakes and people snatch them up and sesell for a price premium and people still buy them second hand May 23 23:07:00 Website and forum was all about hype. It's all a bit sordid. May 23 23:07:38 But they did one *excellent* thing ... made board manufacturers everywhere drop their prices. May 23 23:07:41 major thing that turned me off about it was the lack of exposed gpio immediately, but then secondly and probably more important the community. May 23 23:08:01 everyone has one, but doesnt know how to use it sort of deal May 23 23:08:06 Hehe May 23 23:08:49 Anyway, no worries, it's all ended well. May 23 23:08:59 atleast with the bbb i can possibly glean tidbits here and there and fight my way through the rest of it May 23 23:10:28 wonder if buying the book bad to the bone would be worth it to me. read the index, still couldnt make that determination. May 23 23:10:38 I think if we can help improve the DT utils and the PRU support, beagleboard.org could make an awesome play of BBB being THE board for engineering education. May 23 23:11:13 personally what I think i need it a book in a how to like format that guides me through settign up the toolchain precisly and properly. May 23 23:12:03 yeah i wouldnt mind contributing myself, but i dont know how long i would be in a position myself to do that. im still up to my eyeballs in literature May 23 23:13:03 never written software for linux either. still learning g cc/gdb(though i do have some experience from previous toolchain) DT, pinmuxing, yeah too much to remember May 23 23:13:33 Aye, brain explosion is a serious danger in this game :P May 23 23:14:10 if you know the saying jack of all trade master of none . . .thats how im starting to feel right now lol May 23 23:14:41 Speaking of explosion, there's an implosion coming if I don't cook something. Cya later :-) May 23 23:14:49 later May 23 23:14:52 ok can someone refresh my memory what the # in a %#x in a format string means? May 23 23:15:08 repeat quantity ? May 23 23:15:18 * m_billybob is half guessing May 23 23:15:28 err May 23 23:15:39 sorry string format width May 23 23:16:16 man 3 printf May 23 23:17:05 it means print a 0x prefix May 23 23:18:31 yeap wonder wtf i was thinking of May 23 23:18:33 http://www.cplusplus.com/reference/cstdio/printf/ May 23 23:18:40 good site for quick reffference btw May 23 23:19:31 mru: ah right but isn't that default action anyway May 23 23:19:34 * i guess is what i was thinking of May 23 23:19:57 oh wait duh May 23 23:27:06 Oooh, nice. http://www.goldmine-elec-products.com/prodinfo.asp?number=G19456 May 23 23:29:43 never seen anyone get excited about a dipswitch May 23 23:30:13 mranostay: You've clearly not spent enough time around me. May 23 23:30:44 Shadyman, you'd probably pas out from over excitement here then May 23 23:30:51 m_billybob: :o May 23 23:30:53 Probably. May 23 23:30:58 we've got ~300 arcade PCBs. May 23 23:31:03 all with dip switches May 23 23:31:05 ooo May 23 23:31:26 not necessarily just dipswitches, though May 23 23:31:37 yeah all kinds of goodies on them May 23 23:31:55 many of them are functional too. my buddy, thats his favorite hobby May 23 23:33:10 small list -> http://www.arcade-museum.com/members/member_detail.php?member_id=335709 May 23 23:33:32 I know some guys who would be in 7th heaven over that list May 23 23:34:28 neatest thing, IMO, is using NVRAM for high score storage :3 May 23 23:34:39 or FRAM, even May 23 23:35:25 for me neatest thing is playing them. May 23 23:35:30 well some of them May 23 23:35:58 of course May 23 23:37:00 I find electronics interresting, but on that level, yeah I dont know how much i could get into it May 23 23:37:30 he's very good at repairing them, makes him happy so yeah . . . his thing not mine May 24 00:00:03 mranostay: you about? May 24 00:01:37 mrpackethead: He was May 24 00:01:50 hwe will be back May 24 00:02:06 He's probably gone into hiding to play with dipswitches. May 24 00:14:42 I hear mranostay is adding ISA card support to android for intel May 24 00:15:32 i hear mdp is adding ___ support to ____ for _____ May 24 00:15:35 ;) May 24 00:16:05 I have read somewhere beagle bone black have a seperate microcontroller in it to do arduino like functions May 24 00:19:24 Shadyman: bitbang, rpi, broadcom :) May 24 00:19:40 neoxharsh: PRU? May 24 00:19:58 mdp: Giggity. May 24 00:20:47 http://elinux.org/Ti_AM33XX_PRUSSv2 May 24 00:22:56 mdp: cute May 24 00:24:26 mdp: I thought rpi stuff was hush hush here? May 24 00:24:57 right! May 24 00:25:02 hehe May 24 00:25:20 * mdp goes back to bbb userspace arduino May 24 00:26:27 what do you mean rpi stuff here is hush hush ? I thougt it was rather hillarious the other day when that guy came in askign why rasbian wouldnt compile for his bbb . . . May 24 00:26:34 shhhh.. the pru is a secrect May 24 00:26:51 almost as funny as the two guys asking if they could upgrade the ram o nthe bbb to 3 gb May 24 00:27:09 almsot as funny as expecing a BBB to work out of the box May 24 00:27:36 well you know presumably you have to plug it into a power source of some sort May 24 00:28:40 but i dont know i pulled mine out of the box and it was already blinking on its own so . . . May 24 00:28:46 ;) May 24 00:46:09 someone ran into my car in the parking lot :( May 24 00:46:45 luckily though he's a reasonable guy. and i felt sorry for him weirdly enough May 24 00:47:15 Another cross compiler question -> Other than the std c/c++ libraries what else do i need ? Im compiling for debian, from x86 May 24 00:47:33 I once had a very old lady run into my car while i was at the red signal waiting for it to turn green May 24 00:48:39 deos anyone know, what licence the BBB hardware is under? May 24 00:49:48 quick google search mrpackethead -> Creative Commons Attribution-Share Alike 3.0 license May 24 00:50:34 oh my bad never mind thats content on the site lol May 24 00:50:43 * m_billybob slaps self May 24 00:51:40 Gday all, has anyone tried enabling the crytpo device module on the beagle bone? I know the omap AES support is enabled just not sure how to get openssl to use it May 24 00:52:09 mdp: did you ever get a chance to measure perf of cyclic_dma from any peripheral to ddr on am33xx. If that's even supported? May 24 00:53:13 wolfeidau: i have, recently mainline support is added but you need openocf / cryptodev (both of which are not yet in the kernel) May 24 00:53:39 wolfeidau: either of the 2 are the glue between the AES driver and openssl May 24 00:54:13 joel_: Ahh yeah just read the page on ti wiki, trying to glue all the pieces together :) May 24 00:54:27 hehe. May 24 00:54:38 joel_: Have you tested to see how stable it is atm? May 24 00:55:02 wolfeidau: its pretty stable, but just that there's not one place you get all the pieces (unless you use the TI SDK) May 24 00:55:48 here are the options: you either apply cryptodev/openocf both of which are out-of-tree kernel patches and rebuild your kernel May 24 00:56:16 joel_: I saw that a few companies are using the cryptodev stuff looks like a great idea hving a common device which many vendors can integrate with but openssl doesn't have to worry about May 24 00:56:20 or, you patch openssl for AF_ALG support and the stock mainline kernel will work straight out May 24 00:56:52 joel_: Yeah not sure if i should patch my openssl or the kernel.. May 24 00:56:53 since I'm a kernel developer, I don't like out-of-tree kernel patches much :), so I just patched OpenSSL May 24 00:57:01 haha May 24 00:57:29 I would rather do it in the kernel and not mess with userspace packages :P May 24 00:57:38 wolfeidau: cryptodev is relatively recent, and is constantly updated, if you're familiar with kernel module building you can just build that May 24 00:57:53 but note that cryptodev will always be out-of-tree since its rejected by kernel community May 24 00:58:03 but it still works May 24 00:58:13 openocf on the other hand is not even maintained any more May 24 00:58:26 o is it a licencing thing or just don't like it? May 24 00:58:28 af_alg support is in the kernel already May 24 00:58:55 wolfeidau: crypto maintainer feels af_alg already does same thing , even though its over network sockets (instead of /dev/crypto) May 24 00:59:07 I'd like to install arch on my bbb but my new monitor (with hdmi) hasn't arrived yet, is there some other way I can get it installed without video? May 24 00:59:36 Ok wow I would prefer to use af_alg then May 24 00:59:52 tdilly using a dedicated machine or VM to build then setup a CF card ? May 24 00:59:59 wolfeidau: yeah, just have to rebuild openssl :) and getting the config options straight might be painful May 24 01:00:34 joel_: OK I will give it a shot May 24 01:00:37 least painful route is build cryptodev as a kernel module May 24 01:00:40 joel_: Thanks a heap May 24 01:00:44 m_billybob: ooh good idea May 24 01:00:45 but if you're brave and have time, go ahead with af_alg May 24 01:00:51 sure thing May 24 01:00:57 tdilly, too obvious ? May 24 01:00:58 joel_: hmmm i will try both :) May 24 01:01:23 cool :) happy hacking ;) May 24 01:01:40 mrpackethead: any unspoken fpga pcbs left? May 24 01:01:41 m_billybob: yeah, I was over thinking it :) May 24 01:01:47 tdilly, keep in mind im not being sarcastic. ive recently done this with debian myself, but dont know arch/linux steps May 24 01:01:51 kaektech: yes, there are May 24 01:02:43 m_billybob: Are you running debian on your bbb? May 24 01:02:48 yes May 24 01:02:59 kaektech: the first ones left this morning. May 24 01:03:28 tdilly, technicaly running it on two bbb's one mine the other i setup for my buddy too May 24 01:03:36 mrpackethead: I've got no access to reflow atm. any chance of getting a populated one? May 24 01:03:54 kaektech: you can build it all with an iron May 24 01:03:57 no need to relfow May 24 01:04:31 tdilly -> http://eewiki.net/display/linuxonarm/BeagleBone+Black *maybe* he has arch/linux setup steps too ? I didnt look passed debian May 24 01:04:38 m_billybob: I'm not too fond of Angstrom so far and was looking for something with more packages, and more docs, I had used arch in the past is the only reason I thought of that first, I'm typically a RHEL user but I didn't find any recent fedora ports. May 24 01:05:05 mrpackethead: how much was it again $14 (US b/t/w)? May 24 01:05:21 $14 for the board. $4 airmail to the US May 24 01:05:44 the bom, will cost you about $25 at Digikey May 24 01:05:45 m_billybob: I wouldn't be against trying Debian either, I might do that May 24 01:06:05 tdilly: i'm running debian on the bbb, nad its doing very well May 24 01:06:22 tdilly i know a few people who seem perfectly happy with it, I definately am myself, but havent really done too muc with it yet May 24 01:06:31 kaektech: do you want one? May 24 01:06:40 or 5, for %60 May 24 01:06:43 it comes with most everythign angstrom comes on it except this was a console only setup May 24 01:06:53 mrpackethead: yes. how do I remit? paypal, bitcoin, lindendollars? May 24 01:06:56 apache server, openssh-server etc by default May 24 01:06:59 paypal. May 24 01:07:10 runs a blinky app to, but not quite sure how yet May 24 01:07:24 eg not sure if its native of what May 24 01:07:25 sorry you have missed todays post May 24 01:07:30 but, it can ship on monday May 24 01:07:33 or what* May 24 01:07:59 joel_ do you know much abotu cross compiling for the bbb ? May 24 01:08:40 mrpackethead: your email or mine for details? Yeah, I work in a bank. No IRC, only logs via the web. May 24 01:09:04 joel_, real simple question, if so, looking for hints which libraries i may need additional the the std lib stuff for cross compiling form another OS May 24 01:09:32 ahhh. May 24 01:09:34 additional to the std lib stuff for cross compiling form another OS May 24 01:09:57 kaektech: send an email to me at andrew.frazer@stellascapes.com May 24 01:10:17 with your shipping details.. i'll send a paypal request to you May 24 01:11:21 if this pcb run goes ok, I might run another one for another popular cape May 24 01:11:40 if the capes are double sided, then they will be quite a bit cheaper May 24 01:11:48 but this one is 4 sided May 24 01:11:51 sorry 4 layer. May 24 01:12:45 mrpackethead: sent. Four sided pcbs would and an extra layer of difficulty... May 24 01:13:23 kaektech: 1 board? May 24 01:13:33 yes May 24 01:15:00 too general a question i guess May 24 01:15:05 The fpga world is piquing my interest lately. Haven't explored it much, but I (think) I'm in line for a hackrf board. May 24 01:16:00 same here May 24 01:16:05 i am not expert on thse at all May 24 01:16:10 kaektech in that case another link for you -> http://www.taylorkillian.com/2013/04/using-fpga-of-eecolor-color3.html May 24 01:16:14 eric is the guy May 24 01:16:15 :-) May 24 01:16:20 i just did the boards May 24 01:16:59 that guy actually hacked an eecolor board to be a dev board of sorts May 24 01:17:05 for FPGAs May 24 01:17:12 got it runnign a bitcoin client too May 24 01:17:14 Yup, Eric has some cool stuff he's done. followed the bcc link from earlier May 24 01:18:45 he makes synths, you make cool blinken lights. I wonder what other cool stuff people in the channel make for a living. May 24 01:19:04 mrpackethead: how's the dmx cape working? May 24 01:19:14 reworking it May 24 01:19:15 success? May 24 01:19:19 ah May 24 01:19:20 dmx out, fine May 24 01:19:24 dmx in, not a chance May 24 01:20:13 do you source your leds bulk in shenzen (or thereabout) May 24 01:20:20 ? May 24 01:20:38 thanks for the friendly help! Will be back! May 24 01:20:46 yup yup May 24 01:21:20 the boatloads of stuff you can buy by the container load from alibaba cracks me up May 24 01:21:35 kaektech: not shenzhen May 24 01:21:43 korea, taiwan May 24 01:21:48 mostly May 24 01:22:01 we do buy Cree leds out of the Cree factory May 24 01:22:32 which is in Huizhou May 24 01:23:11 the boat loads of stuff in China is just a QC nightmare May 24 01:23:33 mrpackethead: that is the impression i got May 24 01:24:39 joel_: no. I don't yet have cyclic dma support in the driver. as described in the still-not-changed plan, that comes later May 24 01:35:00 mdp: ok May 24 01:36:02 mdp: that is a very good usecase from perf standpoint May 24 01:36:04 you can always test it with the dt mcasp simple-card private edma branch I pushed to my tree May 24 01:36:46 perf is mostly independent of the dmaengine api implementation May 24 01:36:59 mdp: is that only for davinci, i will be happy to test once i can find an am1808 board May 24 01:37:04 kaektech: May 24 01:37:09 i got your mail May 24 01:37:33 joel_: no...I've had the am33xx support for a while May 24 01:37:47 mrpackethead: cool. and paypal confirmation? May 24 01:37:55 just waiting until the base series interuotions went away May 24 01:38:19 tested on the dvi+audio cape May 24 01:38:22 i have noe May 24 01:38:32 my mail is spamboxing all paypal mails! May 24 01:38:35 grr! May 24 01:39:33 mdp: ok that makes it easy May 24 01:41:16 mdp: I have a dvi+audio cape. what are you testing (scrolls up) May 24 01:42:53 kaektech: matt's dmaengine edma driver, drivers/dma/edma May 24 01:43:26 ah May 24 01:48:32 I've already tested it..joel wants to do some perf testing afaict May 24 01:48:52 mdp: which branch was that again May 24 01:49:00 "small explosive bolts in the hinge let you pop the doors and kick your way out" http://www.wired.com/autopia/2013/05/volkswagen-xl1-driven/ makes me want explosive bolts in my F-150, just because May 24 01:49:01 the only mcasp one was 4 months old May 24 01:49:07 my initial stab was to show the right dt only way to do mcasp May 24 01:50:04 mdp: in any case like you dma_cyclic is a future item right. I already know the perf of doing scatter-gather through crypto usage of edma May 24 01:50:13 *you said. May 24 01:51:40 that one works without cape :-P May 24 01:52:09 WIP/mcasp.* May 24 01:52:45 "WIP/mcasp-am335x-3.8-rc3" May 24 01:52:49 joel_: think about it...cyclic performance is bounded by the period. May 24 01:53:02 yes. I'm on my mobile so being lazy May 24 01:53:18 mrpackethead: curious. your use-case for fpga? me, its rf stuff May 24 01:53:30 just messing actually May 24 01:53:37 and the perf doesn't vary even if you wrap dmaengine around it May 24 01:53:45 just wanting to get into the FPGA thing May 24 01:53:51 and this seemed an easy way to do it May 24 01:53:57 having a lnux machine next to it May 24 01:53:58 mdp: ok . yes, unfortunately for crypto doing a continuous transfer can be useful if it is architected correctly May 24 01:54:21 or am I missing something about cyclic May 24 01:54:23 joel_: I forgot about your weird crypto case..different yes May 24 01:54:39 that'll be the first non-audio user May 24 01:54:57 joel_, thats where I've had the most trouble with the SoC's...their performance doing Crypto for any length of time without just becoming Slugs. May 24 01:55:01 audio is relatively slow May 24 01:55:16 hehe May 24 01:55:32 and these parts aren't designed for performance May 24 01:55:43 even for crypto perf is usually not an issue, but every once in a while some weird usecases come up May 24 01:55:45 mdp, no kidding :P May 24 01:55:59 suggest you get a fsl ppc with dpaa for serious work May 24 01:56:11 and then the design team put out an extrememly theoretical number which keeps getting slapped back =) May 24 01:56:28 mdp, I just do it in an FPGA. May 24 01:56:31 well, now this is very easy May 24 01:56:32 https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=PFPRARLC57NTC May 24 01:56:37 joel_: they always lie May 24 01:56:43 like with PM May 24 01:57:13 mdp: infact it is so pathetic that all the integration related perf drop was not considered, and then linux is blamed May 24 01:57:16 May 24 01:57:37 it's the ideal scapegoat May 24 01:57:58 anything other than baremetal code is sorcery May 24 01:58:14 hehe, and yet everyone wants Linux ;-) May 24 01:58:32 it's a paradox May 24 01:58:58 eerything is bare metal May 24 01:59:04 next we'll run into bearded Spock May 24 01:59:16 i have a client May 24 01:59:20 who just oked an project May 24 02:00:44 Neckbeard Spock May 24 02:01:46 kaektech, what frequencies of RF with the FPGA stuffa? May 24 02:02:28 mrpackethead, did you send the invoice? May 24 02:02:34 yes May 24 02:02:35 i have May 24 02:02:35 boing May 24 02:03:22 just double checking May 24 02:03:54 Bingo! May 24 02:03:54 mrpackethead: bing May 24 02:04:08 bing it May 24 02:07:07 geeks and sun do not mix.... May 24 02:08:19 ka6sox: not sure yet. Still new to the FPGA world. I guess whatever I can wring out of it? (legally) May 24 02:09:23 kaektech, is there an illegal way? May 24 02:09:53 ka6sox: mostly, I've been messing about on the rx side with an rtl-sdr dongle. May 24 02:10:02 ah, okay May 24 02:10:23 Dunno. Studying for my technician test next weekend. May 24 02:10:38 I'm interested in a fdmdv modem for the Bone. May 24 02:11:38 so after i run a bitbake cloud9-image .. is that supposed to create a *.img.xz ? May 24 02:12:02 anyone know how to modify the default resolution per uboot/ubuntu for a BBB? defaults to 1080p@24 as evidenced by fbset, just wondering how I could modify that, thnx... May 24 02:12:28 s4nt, to what? May 24 02:12:46 1280x720@50 I believe May 24 02:13:00 xrandr doesn't seem to play nice May 24 02:13:20 std kernel flag ? May 24 02:14:22 kaektech, I the the BCC has enough space in it for the modem. May 24 02:14:25 if you try 'xrandr --output HDMI-0 --mode 1280x720 ' or pretty much any setting, or framerate, it just ends up being something else, like if you try 1280x720, it sets your resolution to 1280x914, which is odd May 24 02:14:31 Rick, hold on let me look May 24 02:14:37 ka6sox: awesome May 24 02:14:39 if i can find it May 24 02:15:37 Rickta59: from my usage of OE in historical times, the emitted file is of that form. take that with a grain of salt May 24 02:15:44 dinner time, later May 24 02:16:44 all i see are Cloud9-IDE-beaglebone.tar.xz May 24 02:16:55 Rick basepath ->/setup-scripts/build/tmp-angstrom_v2012_12-eglibc/deploy/images/beaglebone/ Anythign there ? May 24 02:17:07 yeah May 24 02:17:11 tar files May 24 02:17:24 what about uboot.img and MLO ? May 24 02:17:40 yeah .. May 24 02:18:36 guess i misunderstood your question. May 24 02:18:45 http://dpaste.com/1197137/ May 24 02:18:51 you looking for a roofs archive ? May 24 02:18:56 i don't see anything that is a compressed img file May 24 02:19:00 that is of the right size May 24 02:20:43 Ok, i think ill bow out here. Dont think i can add anythign useful/helpful May 24 02:21:19 I had not actually gotten passed this part myself so anythign i say would be pure speculation May 24 02:23:45 ka6sox: are you the same fella that has the rtlizer recipes on github? May 24 02:26:56 kaektech, nope May 24 02:30:40 got it, the resolution, via xrandr, you merely have to use cvt and add custom modes for 'HDMI-0' via xrandr per the output from cvt and its now solid, currently at 720p@50hz, thnx... May 24 02:33:18 "The Device Tree support will initially be a pain for developers, but should pay off in the end." May 24 02:33:34 * ka6sox wonders where the payoff is.... May 24 02:33:48 obviously *somebody* got paid off... May 24 02:33:54 ka6sox: feel free to leave comments... May 24 02:34:05 ka6sox: you know how i feel about device tree May 24 02:34:55 ka6sox: as far as i am concerned, it is the very first design choice for the linux kernel that can be classified as a total "F-up" May 24 02:35:57 prpplague, its been a "challenge" I'll say that... May 24 02:36:27 ka6sox, no need to work with data in C format, which only neckbeards can parse May 24 02:37:10 the easily readable pinmux info in .dts files is a huge payoff ;) May 24 02:37:58 mdp: ding ding ding! May 24 02:37:58 yes pinctrl-single usage seems like going back in time :'( May 24 02:38:01 oh right...is that why I needed to have my 11yr old write a web app so I didn't have to have 4 documents open to figure out what to do? May 24 02:38:02 mdp: we have a winner! May 24 02:38:20 pinmux.tking.org May 24 02:38:36 ka6sox: holy cow May 24 02:38:40 ka6sox: that is awesome May 24 02:39:08 ka6sox: where do we donate their minecraft account? May 24 02:39:20 ka6sox, I didn't study under mru just to let my trolling skills go to waste May 24 02:39:28 I'll get you that information...he would LOVE it... May 24 02:39:42 that is for the BBB ka6sox ? May 24 02:40:03 prpplague, he is writing pinmux2 that will do all the pins on a White and black and find conflicts too. May 24 02:40:15 Rickta59, it works for both. May 24 02:40:37 so its designed to replace the pinmux 'Doze app thingy but for 'Bones May 24 02:40:38 ka6sox: nice! when he is done, lets get that posted on linuxgizmos.com, hehe May 24 02:40:53 will do. May 24 02:40:56 pin id is the pin on chip, the pin on the headers? or something else? May 24 02:41:16 its the name that the designer of the bone calls it. May 24 02:41:35 the P(x) name he called it. May 24 02:41:55 k .. i haven't go that far May 24 02:42:02 mdp, we can all take lessons from him :) May 24 02:43:17 ka6sox: actually what we need is a better pinctrl driver than pinctrl-single like some other SoCs use May 24 02:43:26 that make it easier May 24 02:43:28 https://github.com/energia/Energia/wiki/Hardware#wiki-LaunchPad_MSP430G2553 May 24 02:43:34 ka6sox: but that is so cool May 24 02:43:47 get your 11 year old to do something like that but interactive May 24 02:47:42 Rickta59, just showed him that...he gets it May 24 02:48:09 :) .. May 24 02:48:16 yeah i have my son do webpages for me now May 24 02:48:39 he has a much better eye for it than me May 24 02:50:25 :) May 24 02:50:37 so i think i figured out what i was missing .. May 24 02:50:49 apt-get install bitbake May 24 02:50:49 Rickta59, I can't do webby stuff...too many years of Assembly Language. May 24 02:51:08 did someone make a debian package for it? May 24 02:51:20 Rickta59, what guide are you following? May 24 02:51:31 not last time i checked but i think hes on ubuntu May 24 02:51:40 i'm following the treasure map and google searches May 24 02:51:49 is there a guide that tells you want to do? May 24 02:51:56 i sure didn't find it May 24 02:52:08 Rickta59, what is your goal? May 24 02:52:15 to add ntfs to angstrom May 24 02:52:27 for the BBB May 24 02:52:33 with the demo image May 24 02:52:41 i don't care about gnome though May 24 02:52:54 prpplague, something like this: https://github.com/energia/Energia/wiki/Hardware#wiki-LaunchPad_MSP430G2553 << But interactive? May 24 02:54:07 ka6sox: missed your message somewhere along, part of the reason crypto is so slow is because of the splitting of data into chunks by design May 24 02:54:57 the crypto blocks are not always aligned well. May 24 02:54:58 ka6sox: nice!!! May 24 02:55:40 hey stop stealing my ideas :) May 24 02:55:53 Rickta59, you were the one to point it out :P May 24 02:56:35 probably could do it with a google spreadsheet May 24 02:56:36 ka6sox: well in my usecases, alignment has been correct May 24 02:58:10 https://docs.google.com/spreadsheet/ccc?key=0AhIbUzSEOlORdHh6QjJRZXdmY0ZPc2dER1loWHVUM2c&usp=sharing May 24 02:58:16 maybe something like that May 24 02:59:23 that looks familiar **** ENDING LOGGING AT Fri May 24 02:59:58 2013
