**** BEGIN LOGGING AT Tue May 13 02:59:59 2014 May 13 04:16:16 I've read that I can't put voltage into the BBB GPIOs when the BBB isn't powered up and initialized yet. How do one deal with the common scenario of having a single 5V supply which also feeds sensors into GPIOs? May 13 06:07:01 Hi All, I have BBB, I have enabled CONFIG_MMC_DEBUG=y to get logs. but some how I dont get complete logs. Is it possible to get the complete log from boot, e.g. save the log to a file. May 13 06:27:21 logs are saved to /var/log/dmesg by default May 13 06:27:57 if you want extra verbose debugging, you should look up kernel command-line options .. for something like xyzmod.debug=nnn May 13 06:28:54 The_Ball .. you need to carefully switch your power supplies so that the BBB comes up first May 13 06:44:49 vermit`AFK : root@beaglebone:/var/log# ls README btmp journal lastlog wtmp May 13 06:44:57 I dont see dmesg May 13 06:45:51 Also I want logs from start, If i do dmesg then I do get logs but those are not complete. May 13 07:53:46 i wonder how i'm going to access adc mux pins on bbb pmic May 13 08:23:25 Hi all May 13 08:23:44 any win8 usb driver developper? May 13 08:43:54 MoraMora: certfified? May 13 08:44:30 Hello everyone ! I just received my beaglebone black and I was wondering where I could find a tutorial on how to rebuild the angstrom distribution ? (I struggle to isntall openembedded and bitbake and to find non dead links...) May 13 09:05:14 no one here ? May 13 09:29:21 for some reason I can't get anything out of J1-5 May 13 09:29:34 is it configured by default? May 13 09:53:03 man I wish they still hat the ftdi on the beaglebone black May 13 09:53:12 I could do without the onboard flash May 13 09:53:32 finding the right usb-serial adapter and wiring it up without possibly frying the board May 13 09:53:53 some have +-12V +-10v +-5v, some 0/5v or 0/3.3v levels May 13 09:54:19 finally got it to work with a bus pirate May 13 09:54:31 where that didn't work on the original beagle board at all May 13 09:54:46 it would only work with the delock converter I was just trying May 13 09:55:03 which this BB did not like at all May 13 09:56:09 also, why ship with a linux that seems to not do usb hotplugging May 13 09:58:12 then there is no /var/log/messages or syslog May 13 09:58:43 as much as I like the beaglebone May 13 09:59:09 there is a lot of hurdles even for people with some embedded linux expirience May 13 10:08:11 heeen: rumour has it the new BBBs come with debian May 13 10:08:28 yeah I'm gonna go with ubuntu from sd May 13 10:08:40 bleugh! May 13 10:09:08 its just a well supported and up-to-date debian :) May 13 10:09:23 s/well/badly/ :-D May 13 10:14:25 hi May 13 10:17:05 Just got my BeagleBone Black. May 13 10:17:11 \o/ May 13 10:17:29 you can join the Ive got one and you havnae conga May 13 10:18:08 I need to read data from a USB SerialPort, with has a Xbee Explorer connected May 13 10:19:26 var serialPort = new SerialPort("/dev/????"); anyhelp? May 13 10:21:54 ze_: you beagle has a usb->serial connector plugged in? Im not familiar with xbee explorer May 13 10:22:04 ze_: if so /det/ttyUSB0 May 13 10:24:31 Hi, need help with the BB xm boot May 13 10:26:16 anyone? May 13 10:28:02 do you have a question? May 13 10:31:31 I tried ttyUSB0 and tty-usbserial0, May 13 10:32:13 in output: debugger listening on port 6440 May 13 10:32:21 but nothing else :s May 13 10:34:35 hi May 13 10:45:51 BeagleBone Black, read USB SerialPort ? how can I ? May 13 10:47:24 ze_: if i get your question right, it's not possible. the uart is not on the usb port anymore like the one of bbw... there's a 5 (6?) pin header with the signals, but you'll need an ftdi chip (or similar) or a max3232 (or similar) May 13 10:47:52 ze_: but there are converters May 13 10:50:39 thanks Rotti May 13 11:02:45 jo May 13 11:02:47 hi May 13 11:02:51 i have question May 13 11:03:03 please help me May 13 11:06:20 does any can help me? May 13 11:06:39 can anyone help me? May 13 11:06:42 please? May 13 11:06:58 i am problem with socket.io May 13 12:15:14 Still no one to point me toward a up to date guide on how te rebuild the angstrom distrib please ? :) May 13 12:16:55 i saw that on google yesterday May 13 12:17:45 yeah so do I but I tried something like 3-4 guides and all of them leads to links that don"t exist anymore :( May 13 12:18:32 ahh well i saw them as i was looking around for help on rebuilding arch for beaglebone May 13 12:18:53 did you manage to do it ? May 13 12:20:35 yeah im running it now :) May 13 12:20:43 damn ! May 13 12:21:07 did you follow a "how to" guide that you could share ? :) May 13 12:21:18 http://archlinuxarm.org/platforms/armv7/ti/beaglebone May 13 12:21:43 that gives you a base arch install May 13 12:23:34 hum ok ok but how to rebuild it ? (truth is that a potential employer asked me to do that in order to show him my ability to discover new things and I'm struggling really badly) May 13 12:24:59 http://dev.ardupilot.com/wiki/building-for-beaglebone-black-on-linux/ May 13 12:25:11 this details how to do it on ubuntu May 13 12:25:34 however ignore the parts refering to ardupilot itself May 13 12:26:23 hum ok thanks I'll give it a try ! May 13 13:16:09 Morning all, I'm hoping someone can help me. I need to get the P8 header as GPIO from the beagleboard black. Every example I'm finding simply steps over the emmc/HDMI headers except for how to disable them. Can I get this many GPIOs out of the BBB or am I really limited to the scattered 32 default GPIOs ? May 13 13:17:16 you can get like ~60 GPIOs May 13 13:18:53 have a working reference? May 13 13:24:16 hello.. can anyone comment about environmental temperature range of beaglebone black? May 13 13:25:19 it’s not in the manual? May 13 13:25:43 no May 13 13:26:04 the arm chip is probably the most sensitive.. May 13 13:27:05 kaubha_: its not an industrial part May 13 13:27:14 there is no guaranteed temp range May 13 13:27:23 http://processors.wiki.ti.com/index.php/AM335x_Thermal_Considerations May 13 13:27:25 if you need industrial, talk to circuitco May 13 13:27:48 ok.. i need it upto 70 degree May 13 13:27:56 Celcius? May 13 13:28:00 yes May 13 13:28:09 should work May 13 13:28:14 that link says 0 to 70C May 13 13:28:37 and i can’t imagine any other components on the board have a smaller range May 13 13:29:16 its not just the components May 13 13:29:24 PCB, soldering etc.. May 13 13:29:37 main controller is rated for +85 degree C May 13 13:29:44 again, if you need it guaranteed, talk to CCO May 13 13:30:29 but somewhere in google groups they are saying it is 50 degree because of other components May 13 13:30:55 read the page fully, unless it’s industrial version they say ambient temp of 70C May 13 13:32:28 yes.. but that is for controller IC May 13 13:32:43 any idea about other components on BBB? May 13 13:33:08 pmic is to 105C, but i don’t know why i am looking May 13 13:33:22 grab the manual and look up all the major parts May 13 13:33:30 ok May 13 13:34:01 temperature ranges are also applicable to capacitors? May 13 13:34:08 everything May 13 13:34:22 ok.. thanks May 13 13:38:50 Hello, I am trying to connect a light sensor to a BBB - does anyone know what are the pins for the sensor ? Also I will run Android on the BBB. May 13 13:44:42 isisescul: The pins vary completely on the very specific light sensor you want to use. I recommend you pull the datasheet for the light sensor and then cross reference that with the BeagleBone System Reference Manual. May 13 13:44:55 the SRM will tell you what pins have the features you want May 13 13:45:42 I've never run android, save for my phone, so I can't help you with that one May 13 13:47:05 I'm sorry to be this noob but what is my distrib or am I in the kernel now ? root@beaglebone:~# uname -a Linux beaglebone 3.8.13 #1 SMP Tue May 13 13:38:21 CEST 2014 armv7l GNU/Linux May 13 13:49:09 Thank you jbdatko ! I kinda have to run Android - it's a specific application that requires an in-house rom and a light sensor - The one I have got has for connectors and I have no idea how to find it's data sheet . May 13 13:51:09 isisescul: So, if you physically have the sensor, you can look on it for some sort of marking and then google that with "light sensor". I've done this for random chips, sometimes it works; depends on the manufacturer May 13 13:52:39 I don't work too much with light sensors. I would imagine they have typical configurations? May 13 13:54:05 StevePeat: If you recently acquired or upgraded your BBB, then you are probably running debian. Although I would have expected something like "3.8.13-bone47" May 13 13:58:05 jbdatko: here's the sensor http://goo.gl/7ZFKOL not too much on the www - after a few hours of research... May 13 16:06:05 Hey - did someone know what the a high and low on an io is in voltage? May 13 16:06:50 I belive its TTL? May 13 16:07:15 Bibo: see the AM335X datasheet May 13 16:07:30 hi av500 May 13 16:09:13 hi woglinde May 13 16:09:17 back on earth? May 13 16:11:52 @av500 sometimes May 13 16:22:18 is it normal that the mmc0 usr led is blinking rapidly all the time May 13 16:23:18 av500: is there a difference between the BBB serial and the BB C3 serial in terms of ttl levels May 13 16:23:42 BBB works with my bus pirate but not with the delock converter May 13 16:24:01 BB C3 works with the DELOCK but not the bus pirate May 13 16:25:30 yes May 13 16:25:36 BB C3 is RS232 levels May 13 16:25:42 +/- 5V May 13 16:25:48 BBB is TTL May 13 16:25:53 0V/3.3V May 13 16:25:55 I see May 13 16:26:01 <__butch__> Morning folks (at least here in CA). I asked a question yesterday and didn't get a chance to stick around for the answer. Does anyone know how to change the default port for Cloud9 from 3000 to something else? May 13 16:26:07 wish the BBB still had the converter on board May 13 16:26:15 these different serial standards are just a mess May 13 16:26:35 heeen no? May 13 16:26:37 av500: is there a possibility to damage the port using +-5 levels May 13 16:26:48 heeen yes May 13 16:28:51 woglinde: the mess is you need possibly 3 different usb to usart converters, +5v/-5v, 5v/0v, 3.3v/0v, or even +-10v May 13 16:29:02 if you have a couple of devices May 13 16:29:16 the bb white was no fuss compared to that May 13 16:30:03 doesn't rs232 even say +-12V May 13 16:36:38 is the mmc0/USR2 led blinking on angstrom? May 13 16:36:54 when the board idles May 13 16:59:32 nice. configuration updates for beagleboneblack in Debian's kernel were committed. unfortunately USB is pretty much useless... May 13 17:00:29 USB with DMA doesn't really work with multiplatform kernels... :( May 13 17:19:45 "USER2 is an activity indicator. It turns on when the kernel is not in the idle loop." <- where can I find this documented May 13 17:21:23 ah got it May 13 17:21:36 cat /sys/class/leds/beaglebone\:green\:usr*/trigger May 13 17:23:49 wordup May 13 18:47:33 did I remember it correctly that there is a difference in how fast you can use the gpios from the pru depending if you're using pinmux or the adress thing May 13 18:48:25 gpio device adresses I think it was called? May 13 18:48:41 I skipped that part and went for the pinmuxing directly May 13 19:03:00 Heen yes there is a guy over on the MIT server in #6002 who is doing work with the PRU. he has it running from memory around 200MHz May 13 19:03:18 with IO fast enough to generate RF signals directly May 13 19:20:10 N2TOH: Cool May 13 19:22:33 last we spoke he was reading up on DSP knoweldge before getting sidetracked by a mundane matter May 13 19:29:41 Hey. May 13 19:39:27 Hey all. I've just received a beaglebone black and I'm trying to run the eMMC flash uSD image, but I'm not sure how to do it after reading the wiki instructions. May 13 19:39:47 It appears that all I have to do it insert the uSD card and hold the boot button when I apply power. May 13 19:39:57 What exactly should I expect after that? May 13 19:40:09 a big bang! May 13 19:40:13 j/k May 13 19:40:26 I'm currently seeing a login prompt on the HDMI output. May 13 19:40:31 lol May 13 19:40:35 that would be *terrible* May 13 19:41:23 The instructions I read said that all the USR LED's would turn on after 10 min indicating that the Flash has been programmed. May 13 19:41:24 im sorry i cant help you as i dont own a beaglebone black , just a white one wich only boots from mmc May 13 19:41:26 Isd this correct? May 13 19:41:45 Ok. Maybe someone else will see my quesiton. May 13 19:41:47 just wait for it May 13 19:41:50 patience May 13 19:41:58 can take 20-30m to flash sometimes May 13 19:42:08 but generally May 13 19:42:11 the flasher images May 13 19:42:12 So, I should see a login prompt? There's no other feedback, correct? May 13 19:42:13 at least the latest debian May 13 19:42:16 start into x windows May 13 19:42:23 so you might want to grab the latest image May 13 19:42:47 I think I have it. I've downloaded 'BBB-eMMC-flasher-debian-7.5-2014-05-06-2gb.img.xz'. May 13 19:44:27 Ok, something has changed. Now the LED's are all flashing twice in quick succession with about 1/2 second between flashes. Does that mean it's done or that there's a fialure? May 13 19:49:19 where dyou find the 5/6 image? May 13 19:51:02 https://rcn-ee.net/deb/flasher May 13 19:51:30 In the wheezy directory, iirc May 13 19:52:01 ah those aren't official images i dont think May 13 19:52:52 theyre not fulls ize May 13 19:53:04 the ones from latest images page is like 400+ mb May 13 19:53:06 I'm currently downloading another image from here: http://beagleboard.org/latest-images May 13 19:54:15 I see. So, maybe the image I'm running now is just the wrong one to be using. :-/ May 13 19:55:47 What does the flash programming process look like? All of my LED's are currently flashing every 1/2 second or so. Does that mean it's probably programming the flash? Iirc, the wiki said something about the LED's being on sold when the process is complete. May 13 19:56:03 Does that sounds about right? May 13 19:56:57 peniwize: I was confused upgrading my BBB to Debian also. Apparently, the system is fully up and running while it's flashing. Made me think I had a non-flashing image. May 13 19:57:28 It would be cool if someone made like a youtube video of all that.. May 13 19:57:42 When it's done, the LEDs don't blink anymore. May 13 19:58:24 Supposed to be all 4 on. But I *think* I remember only 3 being on... May 13 19:59:17 It says it takes about 40 min, but I think it was more like 15 for me. May 13 20:00:27 What I'd like to do now it reverse that. Take my running eMMC and back it up to an SD. So I don't have to go back an uninstall everything I don't need.. May 13 20:00:53 dsmith-work: Thanks. It's totally unclear from the online instructions so I'm confused in the same way - or at least I was until you replied. :- May 13 20:00:57 :-) May 13 20:01:53 I tried this last night and it ran for a couple hours with the LED's flashing so I assume something went wrong. Hopefully I'll have better luck this time. May 13 20:02:34 My BBB is currently running a bot (in Guile Scheme) in the #guile channel. May 13 20:03:12 <__butch__> peniwize: You can't have anything plugged into the board. No HDMI, no USB. Power via 5V barrel connector. Hold down the boot button, plug in the power. Wait until you go past the four LEDs lit and they start blinking. Release the boot button. Wait. Wait longer. Wait even longer. When all four LEDs are lit, it's done. May 13 20:03:58 <__butch__> peniwize: It can really take 40 minutes. It can also take 15 or less. It just depends on the size of the image. May 13 20:04:08 <__butch__> peniwize: Hours is too long. :-) May 13 20:04:42 <__butch__> peniwize: Based on your description, because you had the HDMI cable plugged in, it booted. It was happily soldiering along running the OS like it's supposed to. May 13 20:04:49 __butch__: The first time, I waited over night. Then I realised I had the non-flasher image.... May 13 20:06:42 Ahh. OK. If I have stuff plugged in and it causes the flashing process to fail then will it continue to blink and look like it's still programming the flash or will it do something different to indicate that the flashing process has failed? May 13 20:06:44 <__butch__> @dsmith-work: You should be able to copy out of eMCC using dd as long as you know the exact size you want to copy. It's not really such a big deal since you probably haven't filled it completely, and hopefully it's not fragmented and the empty space is still at the end. May 13 20:07:17 <__butch__> @peniwize: The LEDs blink during normal operation pretty much exactly the same way the blink when you're flashing, so there's no real way to tell what it's doing. May 13 20:07:33 Oh! Slick! So all the flashing process is doing it dd'ing an image onto the internal flash? May 13 20:07:52 If so then I could do that manually so I know for sure what's happening. May 13 20:09:06 Will production of BBB Rev B continue, or will Rev C replace it completely? May 13 20:09:21 <__butch__> @peniwize: Yes, if you look at the disk partitions via mount, you'll see that the eMCC is just a disk to the OS. May 13 20:09:58 <__butch__> @peniwize: And at this point I think I'll shut up and get some lunch before I say something wrong and you wipe out a perfectly good BBB. :-) May 13 20:10:26 <__butch__> @JoE6: What I've seen indicates that Rev B is done, no more production, and only Rev C going foward. May 13 20:10:33 <__butch__> ^foward^forward^ May 13 20:10:53 <__butch__> Back in a bit . . . May 13 20:12:38 __butch__: thanks for the help. May 13 20:15:10 And of course, the purpose of copying it to SD is so that I can re-flash it from that if I need to. May 13 20:15:39 grrrr my kernel is panicking as it cant find the busybox init now :| May 13 20:19:08 @__butch__ Merci for that observation. If the availability of BBB is going "forward" I will have to swallow the increase of 18%... May 13 20:20:36 lol May 13 20:20:41 because its priced out of affordability now May 13 20:20:42 clearly May 13 20:22:23 Maybe the BBB was way to cheap to begin with.... May 13 20:24:32 Why would they keep two revisions around? May 13 20:24:52 Or, you mean two price options? May 13 20:27:43 There is always a price sensitive market. With education each cent counts - and for Blinken LED a 45$ device is as good as a 55$. May 13 20:31:57 Sure. I guess they either decided they can't continue at the same price (maybe production's gotten more expensive, too), or just that the market will bear it. May 13 20:32:34 To blink LEDs you can make do with a <$10 board too. May 13 20:34:02 Is there any word when the Element 14 BBB Clone will be available? May 13 20:35:04 Why prefer it? May 13 20:37:18 JoE6: Thats what I have. May 13 20:37:37 ZiNC: Because you can ge them! May 13 20:37:44 :) May 13 20:37:47 s/ge/get/ May 13 20:39:04 My impression is (looking at the non availability) that a second source is badly needed. May 13 20:40:11 I'm not sure if it's the version you're talking about, but Seeed has a version for $70 seemingly in stock. May 13 20:40:42 Special Computing has the original rev C also for $70. May 13 20:41:45 + shipping, in the case of SC. May 13 20:43:58 I originally ordered from Element 14 with nothing in stock, and after a few weeks I got an email about their substitute version. May 13 20:44:23 I am Germany based. International shipping cost and custom expenses will drive the price into regions that are not acceptable. May 13 20:45:15 Seeed should have free international shipping on that. May 13 20:45:32 All german suppliers are out of stock and a fun dog on ebay offers them for 999 Euro. May 13 20:49:56 the increase in price on the BeagleBone Black was due to needing to switch to 4GB eMMC, and the Debian image needed almost 2GB for the OS alone. May 13 20:50:14 i guess the 2GB eMMC were getting hard to come by, as well. May 13 20:50:22 hi vagrantc. Thanks for the support on #beagle! May 13 20:50:31 happy to May 13 20:50:47 jkridner: looks like they've accepted my config updates in the Debian kernels May 13 20:51:01 saw that e-mail. guess the USB is still a challenge? May 13 20:51:06 jkridner: unfortunately, the multiplatform kernels don't really work with USB DMA... May 13 20:51:09 That can't be the only reason, though, considering the $10 difference. May 13 20:51:42 ZiNC: it is also paying for a 3rd shift and expedited parts to accelerate production. May 13 20:51:43 What's taking so much in the Debian image? May 13 20:51:47 jkridner: but it still is viable for headless use... or a non-interactive kiosk May 13 20:51:54 ZiNC: http://beagleboard.org/blog/2014-04-13-dude-wheres-my-beaglebone-black/ May 13 20:51:59 I understand bigger mem = bigger price. Totally. And more money to produce more boards. May 13 20:52:04 jkridner: I guess improving production is the main reason. May 13 20:52:11 ZiNC: /usr/share/doc is 800MB May 13 20:52:34 How much would it take barebonized? :) May 13 20:52:46 WHAT? YOU LAZY BONES ONLY WORKED 2 SHIFT making ME wait?!?!?! Irony off.... May 13 20:53:00 ZiNC: maybe 60/40, but the 4GB is more expensive. May 13 20:53:28 I wonder how it'll affect sales long term. May 13 20:53:42 But I guess this is a concern for the long term rather than now. :) May 13 20:53:57 interest in the BBB is high May 13 20:54:07 I'm not a big fan of the price increase, but the demand is strong. Strong enough for clones to come on-board at the same or lower price. May 13 20:54:22 There is a market rule on demand and prices too... May 13 20:54:37 jkridner: Are you considering also the "competition", or is it just about getting the hardware you had in mind out? May 13 20:55:30 JoE6: and also supply May 13 20:55:51 on a hot day on the beach, if you have the only ice-cream truck, you can charge what you want. May 13 20:55:52 I wonder if it would make sense to also produce a Lite version, with some less hardware but generally software compatible, for a lower price. May 13 20:56:02 After peeking into the latest Debian and Ubuntu beagleboard eMMC images I've found that LED's that flash twice every 1/2 second or so means that the flash process failed. I also found the script that flashes the eMMC in '/opt/scripts/tools/eMMC/beaglebone-black-make-microSD-flasher-from-eMMC.sh' and I'm running it manually to see what happens. So far so good. May 13 20:56:32 ZiNC: right now, I personally don't make any money on boards, so clones are excellent. May 13 20:56:43 yes, the more the better May 13 20:56:58 I'm more concerned about making it as affordable as possible so as many people can get boards as possible.... May 13 20:57:32 but, the price can't be so low that it is just a marketing gimmick and when suppliers get bored of it being a loss leader, they lose interest. May 13 20:57:35 jkridner: Is the goal at all to be profitable? (I mean beyond breaking even.) May 13 20:57:44 * jkridner is planning for BeagleBoard.org to be around for the long haul. May 13 20:58:11 it's got to be profitable enough the manufacturers don't loose money producing them, at least... May 13 20:58:23 Sure. May 13 20:58:24 ZiNC: profitable for everyone involved, but still lower-margin than typical. May 13 20:58:31 pity that there are some individuals have behaved so poorly, to make yoru job harder jkridner May 13 20:58:50 things seem OK from where I sit. May 13 20:58:59 interest is growing constantly. May 13 20:59:08 Was it ever considered to be out as part of TI's Launchpad? May 13 20:59:31 sure, we aren't R-Pi, but we do more and I think the people that convert become long-term converts due to all the extra capabilities. May 13 21:00:16 We aren't everything we want to be to the hard-core Linux heads, but I still feel the large community will help us get there over time---and we'll be around. May 13 21:00:22 ZiNC: no. May 13 21:00:32 kickstarter for 100,000 units. :-) May 13 21:00:41 BBB >>>> Pi :p May 13 21:00:46 Goal from the beginning has been to leave as little control in TI's hands as possible. May 13 21:00:54 even with its quirks May 13 21:00:56 :) May 13 21:01:41 the way to do that woudl be to be able to dual source the key component May 13 21:02:01 Has the focus shifted more to becoming a higher level computer of sorts (hardcore Linux you say) than initially? May 13 21:02:59 a BBB can handle SDHC without any problems, right? May 13 21:03:21 * jkridner goes back to soldering up some hacks for Maker Faire. May 13 21:03:45 Farewell. :) May 13 21:04:01 mmm solder fumes :) May 13 21:04:03 ZiNC: it has shifted to be more for 'makers' than originally... (originally more for ARM Linux developers) May 13 21:04:08 veremit: Depends on your needs/goals, though. May 13 21:04:17 ofc May 13 21:04:23 there's a number of ARM boards out there now May 13 21:04:29 even low cost ones May 13 21:04:35 jkridner: Oh. I the reverse, more hardware/embedded initially. May 13 21:04:48 * jkridner is concerned about losing the roots though and is trying to think about how best to hold on to the hardcore ARM Linux developers. May 13 21:05:11 ZiNC: was originally more desktop-like focus. May 13 21:05:22 Interesting. May 13 21:05:41 then moved to things like the built-in web-based IDE, etc. May 13 21:05:57 k, now really back to soldering. :-) May 13 21:06:15 Alright. Thanks for the inside background. :) May 13 21:06:26 veremit: Depends on what ARM, though. May 13 21:07:05 ZiNC .. whats your application/ May 13 21:08:03 I mean in general. May 13 21:08:20 What's the cheapest ARM board you encoutered? May 13 21:08:56 cheapest arm board is easy .. has to be the Pi. May 13 21:09:06 cos that was always their key aim. May 13 21:10:08 Oh, you mean with a whole bunch of ready-made connectivity. May 13 21:10:52 the cubox-i seems to be amoung the most consumer-looking cheap ARM devices, but it's kind of a little black box, though more open thanit's cover would let on. May 13 21:11:05 I thought of more minimal stuff, just a chip with support circuitry and some easy way to program and hook extra things up. May 13 21:11:14 <__butch__> Repeat question: How does one change Cloud9 to use a port other than 3000? May 13 21:11:30 as I Say .. its dependant very much on your definition and application .. it could be a $100 unit or a $30 unit :) May 13 21:11:47 __butch__: why do you need to? May 13 21:11:58 __butch__: as that would inform the question... May 13 21:12:13 I don't think anyone has gone sufficiently minimalist to just have a processor, and ram .. thats not a whole lot interesting to many folks. May 13 21:12:38 awesome for embeded stuff tho May 13 21:12:53 ide love one so i could hide it in the dash of a car May 13 21:12:54 The Arduino things are pretty much that. Sans the external RAM. :) May 13 21:13:37 ZiNC .. think you'll find an arduino comes to a very comparable price to the Pi .. but is a totally different animal. Arduino is an awesome platform though. But doesn't have much processing and zilch graphics capability May 13 21:14:03 When did CuBox-i show up? They seem really keen on not showing their hardware. May 13 21:14:07 <__butch__> @vagrantc: I just want to run something else on port 3000 (Ruby on Rails WEBrick). I know how to change its port, but I'd rather use its default port of 3000. May 13 21:14:31 veremit: Surely different target uses. May 13 21:14:51 what may interest you is something like the Arm Cortex M0-M3 series of processors, but again .. I know no low-cost boards (save perhaps the "embedded Pi") which have an entry-level target May 13 21:14:57 beaglebone nd 328 together lol May 13 21:15:34 veremit: Not looking for anything right now, just wondered. :) May 13 21:15:50 The cheapest I recall is one of the small Cypress devkit things. May 13 21:15:55 ARM-wise. May 13 21:16:13 fundamentally you still got a pay a few $ for the chip and a pcb. :) May 13 21:16:33 They have to. You get the assembled thing. :) May 13 21:16:48 yea .. but the cost has to go somewhere ;) May 13 21:17:14 I suspect devkits aren't going for profit in many cases. May 13 21:17:29 Or demo boards, or whatever you'd call it. May 13 21:17:52 ZiNC: i think the cubox-i started shipping early this year? May 13 21:17:54 depends on the platform .. I've seen kits priced at 00s or 000s of $ .. they are making a margin, I'm sure :) May 13 21:18:26 most ARM kits used to be >$200 at one time May 13 21:19:32 It looks like some of the newer manufacturer-provided boards, targeted at the new hobby market of the last few years, are an entirely different thing. May 13 21:19:46 Let me look for it... May 13 21:21:16 Unless they're going for $50 shipping, this is price friendly: http://www.cypress.com/?rid=92146 May 13 21:21:31 nanopc-t1 was one I was looking at. May 13 21:21:32 It's M0. May 13 21:25:13 BTW, what boot time do you get on Debian now, compared with Angstrom? May 13 21:29:22 nanopc.org - if it was working lol May 13 22:19:00 j #beagle May 13 22:19:08 whoa...those are nice May 13 22:46:40 yay finally got vnc working lol May 13 23:42:20 oooo compilling a qt4 app on a beaglebone white is painfull lol May 13 23:43:08 not really agood platform for building apps generally I'd say ... May 13 23:45:20 not when your running arch on it and connecting to the xfce desktop over vnc lol May 13 23:46:01 yikes thats pretty hardcore for a single core at <=1Ghz :p May 13 23:48:13 if this app compiles and runs then i will be the happyest persion alive :) May 13 23:51:57 eventually ;) May 13 23:52:22 haha yeah May 13 23:53:21 thing is im in a position to buy a bulk load of ex manafacturer stock of tablets so im playing with rolling my own systems on arm using my beaglebone lol May 13 23:53:33 how bulk? heh.. May 13 23:54:10 a few :) May 13 23:54:46 eeenteresting. May 13 23:55:40 im not allowed to say where or how many but its enough to keep me fiddling for a bit May 14 01:00:49 ZiNC: I'm seeing about 14s vs. about 8s w/ Angstrom. May 14 01:01:07 Thanks. May 14 01:01:15 8 sec with stock Angstrom? May 14 01:01:45 I haven't looked recently, but here it was more like 20 seconds. May 14 01:02:35 not looking at Desktop time, just boot to usable prompt. May 14 01:04:07 It's been a while, but I must've timed to something sensible. Maybe until getting serial over USB (or just serial). May 14 01:04:21 Will have to check again. May 14 01:46:01 argh &!@#% why the hell didn't they connect RTS/CTS on the serial console ... it's not even that the pins are otherwise in use, they left them not-connected on both the cpu and the serial header >< May 14 01:49:16 Just greenwire them. May 14 01:49:48 ? May 14 01:50:09 patch a wire to... a BGA chip? May 14 01:50:16 Sure, why not? May 14 01:51:33 must be my lack of imagination, but I have difficulty envisioning the patch you seem to be suggesting :P May 14 01:51:44 given that the balls are inaccessible May 14 01:51:51 Not at all. May 14 01:52:05 Just takes a copy of the board artwork, a steady hand, and a fine drill. May 14 01:53:55 Will a 8mm bit do? May 14 01:54:02 Uh, no. May 14 01:54:05 Maybe 0.8mm. May 14 01:54:07 Just checking. May 14 01:54:16 I also have hammers. May 14 01:54:39 But, really, the correct solution is just to make your own board, with those two traces routed. May 14 01:54:40 heh, ok I can now imagine there are people who might do that... I think otoh I'll just see if I can grab another uart *with* hardware handshake from the extension connectors, or implement DMA in my forth's serial code so characters can be received in the background May 14 01:54:49 The bone is, after all, open source. May 14 01:55:49 actually the board I'm primarily working with is custom and does have hardware handshake on the console obviously :P May 14 01:56:01 but I want to port my forth system to the beaglebone May 14 01:57:44 and right now that's not gonna work without rts/cts, since I need to paste a large blob of tekst on top of the kernel, which right now operates the uart in polling mode so the flow really does need to stop while it's interpreting a line of code May 14 01:58:38 nice May 14 02:01:05 switching to using DMA was on my to-do list anyway :P but temporary solutions that work kind of adequate have a tendency to stick around for longer than they ought to May 14 02:08:41 very true **** ENDING LOGGING AT Wed May 14 02:59:59 2014
