**** BEGIN LOGGING AT Thu Aug 14 02:59:59 2014 Aug 14 04:15:14 rpis have a config.txt on their boot partition to indicate certain hdmi settings. Does beaglebone have something similar? Aug 14 04:15:22 does the beaglebone distro* Aug 14 04:19:01 Jesperhead: you can edit the bootargs in uEnv.txt Aug 14 04:19:26 Jesperhead: that is, presuming, there are boot arguments that do what you want. Aug 14 04:19:49 vagrantc: precisely... ill google for resources about them, do you have any suggestions? Aug 14 04:20:15 thank you about uEnv.txt, im unfamiliar with debian and just got my bbb Aug 14 04:22:22 it's more a u-boot thing than a debian thing... and not all u-boot builds support uEnv.txt Aug 14 04:22:29 u-boot is a bit... fractured. Aug 14 04:22:40 oh then this should be a blast Aug 14 04:23:31 well according to this: http://www.element14.com/community/community/raspberry-pi/blog/2012/09/27/raspberry-pi-lapdock-hdmi-cable-work-around I think i want to try mimic the config as best I can Aug 14 04:24:02 sorry, try this one http://www.element14.com/community/community/raspberry-pi/blog/2012/09/27/raspberry-pi-lapdock-hdmi-cable-work-around#comment-17754 Aug 14 04:30:30 hmmm Aug 14 05:07:29 hmmm indeed watson Aug 14 06:33:23 May I ask for help? I am now to BBB and I screw it up. The eMMC no longer boot to the default. Any idea how do I restore it? Aug 14 06:35:55 get a flasher image, put it onto the sd card, boot it :) Aug 14 06:42:33 The image with BeagleBone Black (eMMC flasher) or without eMMC flasher? Aug 14 06:54:56 Hi! Has everybody tried to boot BBB from microSD? I wrote Ubuntu14 on microSD as shown at http://www.armhf.com/boards/beaglebone-black/bbb-sd-install/ but BBB doesn't boot. Aug 14 06:55:51 I'm not sure _everybody_ has, but many certainly. Aug 14 06:56:03 how did you write the image to the sd card? Aug 14 06:57:29 anybody ) Aug 14 06:57:48 Yes, it's on SD card Aug 14 06:58:44 And I hold th button while powering the board, but LEDs are off and I can't connect to BBB from Linux PC Aug 14 07:01:22 I wrote the inage on SD as shown at site I mentioned above Aug 14 07:01:27 image Aug 14 07:02:55 which operating system do you run on your PC? Aug 14 07:03:24 ubuntu14.04 Aug 14 07:03:48 ok, then please copy paste the exact dd command that you used Aug 14 07:07:00 I didn't use dd command Aug 14 07:07:19 what did you use then? Aug 14 07:08:12 I downloaded Ubuntu : wget http://s3.armhf.com/dist/bone/ubuntu-trusty-14.04-rootfs-3.14.4.1-bone-armhf.com.tar.xz Aug 14 07:08:26 Then mkdir rootfs Aug 14 07:08:40 mount /dev/sdX2 rootfs Aug 14 07:08:49 tar xJvf ubuntu-trusty-14.04-rootfs-3.14.4.1-bone-armhf.com.tar.xz -C rootfs Aug 14 07:09:00 umount rootfs Aug 14 07:09:38 ah manual setup Aug 14 07:09:55 well, you probably made a mistake somewhere along the way when preparing the U-Boot partition Aug 14 07:10:52 maybe. The only thing I can do is to repeat all procedure Aug 14 07:12:11 I've tried to boot BBB connected to PC using usb and the LEDs are on, but can't connect to the board through ssh Aug 14 07:13:53 who knows what this image is configured for Aug 14 07:13:59 also the leds should blink Aug 14 07:15:01 It's said that this image is for BBB... trb, have you written any image on SD? Aug 14 07:15:28 yes, I've written images to SD before it was cool. Aug 14 07:15:56 and I know how many failure modes there are, that's why I prefer ready images Aug 14 07:16:17 forget to marke the partition active? won't boot Aug 14 07:16:26 wrong partition geometry? won't boot Aug 14 07:16:36 wrong FAT parameters? won't boot Aug 14 07:16:43 etc Aug 14 07:17:10 btw: if the LEDs are blinking, then it does actually boot Aug 14 07:17:29 OK. Could you recommend any ready image and a procedure how to write it on SD? Aug 14 07:17:56 the debian image, unpack, dd, boot. Aug 14 07:19:56 Specific debian image or ordinary image intended to install on PCs? Aug 14 07:21:23 no, the one available from beagleboard.org Aug 14 07:22:02 what dd command should I used? Aug 14 07:27:12 http://beagleboard.org/getting-started#update Aug 14 07:28:28 meh, is that windows only? Aug 14 07:30:42 Thank you,I'll try to write image this way. What do you mean "is that windows only?" ? Aug 14 07:35:32 http://elinux.org/Beagleboard:Updating_The_Software Aug 14 07:37:14 ? Aug 14 07:38:22 * tbr sucks at finding a description of the dd;ing Aug 14 07:39:01 it's a small link at the bottom tbr Aug 14 07:39:16 that takes you to ubuntu's site, then you have to scroll down for "command line option" Aug 14 07:39:56 heh Aug 14 07:41:42 tbr, are you familiar with neopixels (adafruit ws leds)? Aug 14 07:48:53 tawr: nope Aug 14 07:49:47 the WS2812S rgb leds with integrated drivers? they're called neopixels by adafruit Aug 14 07:50:14 http://www.adafruit.com/products/1612 is the "mini" product in question (which I got running through the pru's earlier today without issue using Yona's fork of LEDScape) Aug 14 07:54:58 I think mranostay did something with that Aug 14 07:58:15 oh, I had just finished a project and wanted to show it off :P Aug 14 07:58:29 well do so! Aug 14 07:58:34 I made a small (about 1/2") 5 sided cube Aug 14 07:58:36 out of those neopixels Aug 14 07:58:50 http://i.imgur.com/kweCoj9.jpg Aug 14 07:59:01 http://i.imgur.com/U02V0Kh.jpg Aug 14 07:59:08 it was a pretty tight fit Aug 14 08:02:12 oh, cute Aug 14 08:02:19 and yeah, in that size it's a tight fit Aug 14 08:04:14 thanks :) I have some point to point to do on the bottom to finish it up Aug 14 08:04:29 the hard part was figuring out how to "start" the strip that would let me have the final one with a 90 degree top Aug 14 09:03:10 hello Aug 14 09:11:30 ehlo Aug 14 11:47:17 I've run Debian on BBB from SD card but can't remotely access the board through ssh. Debian image doesn't contain ssh server by default, does it? Aug 14 11:47:56 Image is from beagleboard.org Aug 14 12:00:32 Sergey: I think it does. If not you could always just install it... Aug 14 12:04:27 Tbr, if ssh was installed I would be able to connect the board, but I can't:) with Angstrom Linux I don't have such a problem. So I'll need to buy microHDMI cable to connect BBB to monitor and install ssh) Aug 14 12:11:31 Sergey buy a serial console cable Aug 14 12:12:04 I used to be skeptical about if I needed one of those FTDI cables Aug 14 12:12:14 why? Aug 14 12:12:15 I have to say, it was a really good decision, in the end, to buy one Aug 14 12:12:24 because ssh was "good enough" for the most part Aug 14 12:12:25 ah good Aug 14 12:13:00 * woglinde still wonders why people buys developer boards and do not have serial cables Aug 14 12:13:05 I was trying to figure out why Angstrom wouldn't boot after I upgraded the kernel and it was a much more involved process than I thought it would be Aug 14 12:13:23 but yeah, it's a good idea to buy one Aug 14 12:48:33 I have a problem with beaglebone blacks. I connect a GSM modem to UART2 - after some time (5 min to 2 hours) the beaglebone freezes - heartbeat LED stops blinking. no error messages in dmesg or logs. updating/switching kernel did not help. any ideas what to do? Aug 14 12:50:49 (I don't think the fact its a GSM modem has any significance, but maybe the fact that pppd is running using the kernels ppp network device features does? I don't get the freeze happening without pppd running so far) Aug 14 12:51:28 CorvusCorax: What GSM modem? Aug 14 12:52:17 SIM 900 chip talking over 3.3V serial line Aug 14 12:52:32 we used USB modems earlier but had reliability issues Aug 14 12:52:58 CorvusCorax: Ok. I was playing aroudn with the Seeed Studio GPRSS v2 shield lately, which I think is sim9000... Aug 14 12:52:58 therefore the choice to switch to beaglebone with its many uarts and use a serial device which we can power cycle using a gpio Aug 14 12:53:27 problem is, its the beaglebone that acts up , the modem istelf looks fine Aug 14 12:53:38 CorvusCorax: You using 5V power adapter to power it, not usb? Aug 14 12:53:55 sometimes i get a weird state that the beaglebones heartbeat is no longer blinking but i can still issue commands on the command line over Ethernet Aug 14 12:54:04 yes of course, 5V external supply Aug 14 12:54:10 CorvusCorax: oh that's wierd Aug 14 12:54:20 i checked dmesg but nothing Aug 14 12:54:35 [ 32.275722] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [ 303.503589] PPP generic driver version 2.4.2 Aug 14 12:54:39 (last 2 entries) Aug 14 12:55:03 So, I didn't have this happen :) I wonder how much current that sim900 is drawing. The data sheet said that their can be a peak of 2A ! Aug 14 12:55:09 I assume that is for talking though Aug 14 12:55:17 i had that a few times now, its definitely temporary, after a few minutes it freezes up completely and needs hard reset Aug 14 12:55:17 I was just using my for texting Aug 14 12:55:57 yeah, most GSM modems have high peak currents, we chose the external supply accordingly Aug 14 12:56:44 Which distribution are you running on the BBB? Aug 14 12:57:18 the default its shipping with, looks like a debian of some sorts Aug 14 12:57:44 i itried to update the kernel to the "beta 3.15.x instead of 3.8 but that didnt fix the issue Aug 14 12:58:02 CorvusCorax: does it happen without the modem connected? Aug 14 12:58:43 i only managed to reproduce it with modem connected and active with pppd running. if i disconnect the modem pppd will not run. with modem connected but not active i so far also havent had the issue Aug 14 12:58:46 ok. hmmm. Sorry. The best I can do is agree with you that this is wierd :) I don't know why the BBB would lock up other than if maybe if the serial lines are hanging for some reason. Aug 14 12:58:59 but its happening sometimes only after an hour, so maybe i just didnt wait enough Aug 14 12:59:38 serial lines hanging can lock up the entire CPU? Aug 14 12:59:56 Well, that's the odd part for sure Aug 14 13:00:39 i searched google and found someone who had freezes when clocking the uart2 with very high baud rates on bbb, which apparently was no problem on the white one Aug 14 13:00:51 but no explanation or solution Aug 14 13:01:35 but I thought I better ask here if this is a known problem and affects all uarts, before starting to change our hardware design to use different ports Aug 14 13:01:37 I don't have a good explanination, but maybe you could try a different UART? or try using Debian Jessie (different software)? Aug 14 13:02:53 CorvusCorax: I would send an email to the list. You might get an asnwer throughout the day from the U.S. based people as they are just waking up Aug 14 13:02:59 could I do a dist upgrade on the beagle to upgrade to jessie? or would i have to install a new image? Aug 14 13:03:24 I think you *might* be able, although I just always do a new image Aug 14 13:04:36 hm I never heard of lockup via uart too Aug 14 13:04:57 CorvusCorax did you test if the modem runs on another board uart well? Aug 14 13:10:46 I'd probably try two more scenarios: drive the modem UART from a different device; power the modem separately from the BBB. Aug 14 13:15:38 woglinde: not yet that#s one of the next things I'm testing, since it involves soldering Aug 14 13:16:15 first thing im trying is another power supply. allthough the one im using is rated for >2A i dont trust these ratings too much ;) Aug 14 13:27:22 the heartbeat, led - is that a user space process blinking it? or kernel? Aug 14 13:34:58 kernel Aug 14 13:37:01 so it not blinking means something is already very seriously wrong. I guess a kernel level watchdog would likely not help either then :( Aug 14 13:40:44 or that userspace turned it off for some reason Aug 14 13:40:58 although that's unlikely in this situation Aug 14 15:10:48 i have the blinking cursor on the framebuffer (i use an LCD4_CAPE) shining through all my opengl apps Aug 14 15:11:00 but if i disable CONFIG_FRAMEBUFFER_CONSOLE, then i don’t get any display output at all Aug 14 15:11:03 does that sound familiar? Aug 14 15:41:42 http://embedded.von-kannen.net/2014/06/28/how-to-disable-the-blinking-cursor-in-console-mode/ Aug 14 15:41:46 that was the solution (for reference) Aug 14 17:28:47 Hi, I'm trying to run through the Logic Supply tutorial on blinking external LEDs, Aug 14 17:29:29 Im having trouble figuring out how to download the Adafruit_BBIO, I cant access the GateOne SSH Aug 14 17:30:21 I dont see a link for GateOne when I access the BBB webpage Aug 14 17:34:33 find the ip of the BBB and ssh to that one Aug 14 17:50:57 stock BBB's come on a default address if the USB port is used Aug 14 17:53:29 Are there any wifi usb adapters that will work well with a BBB? Aug 14 17:59:29 I've had good luck with the asus usb-n53, a bit pricey for the bbb if you're price conscious, but it's a dualband n reciever Aug 14 18:05:26 Mainly just wanted one that worked more than anything lol Aug 14 18:05:45 I have 3 that wont work, they connect but then fail, even with full 5v2.5A power cord Aug 14 18:07:36 do they download anything, or fail immediately after connecting? Aug 14 18:14:26 wow someone just told me in another channel "try pandawireless they all work" and I have 2 of them here and they dont lol Aug 14 18:14:40 another guy said "roll the dice no wifi works 100%" Aug 14 18:16:19 could be a networking configuration error Aug 14 18:17:36 its just way too easy to configure wifi I couldn't imagine it would be a config mistake Aug 14 18:18:02 especially comparing it to other known working configs Aug 14 18:18:13 what encryption are you using? generally you need to start with no encryption and work your way up to better schemes to rule out software issues with encryption Aug 14 18:20:08 Are you sure the interface isn't incorrectly configured? Aug 14 20:12:39 Hi there! I need help with my BeagleBoard Rev.C4. I found it today and wanted to start but I can't get to the u-boot prompt. Can someone spare some time and help me? Aug 14 20:17:07 Blub__, do you get anything over serial? Aug 14 20:18:54 yes. it is just a loop. this is from my last try http://pastebin.com/2jKdcqRM Aug 14 20:19:28 I tried many guides, includings some of your repos Aug 14 20:21:11 hum, that's a mess.. what happens if you hold the user key, can you get a prompt? Aug 14 20:21:28 (/key/button) Aug 14 20:22:40 Same result with the user button. After holding it for 10 sec it clears the screen from my serial console and reboots. Aug 14 20:24:18 try "unzx"ing this and dd'ing it to an sd card: http://rcn-ee.net/deb/microsd/wheezy/bb-debian-7.6-console-armhf-2014-08-13-2gb.img.xz Aug 14 20:24:50 alright Aug 14 20:24:53 thanks Aug 14 20:40:45 So, I'm back with new error messages. http://pastebin.com/011mSYS5 Aug 14 20:41:11 This is the boot log with pressed user button Aug 14 20:42:09 so even with that, you can't get into the u-boot prompt? Aug 14 20:44:22 Yes. No prompt just a boot loop. Aug 14 20:45:12 Guess I have to try booting over USB or UART. Aug 14 20:46:53 Blub__, also try: http://angstrom.s3.amazonaws.com/demo/beagleboard/Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img.gz That was around the same error as MLO that is stuck in your nand.. Aug 14 20:47:10 s/error/era/ Aug 14 21:19:44 Back again. Sadly no success. http://pastebin.com/zLySp6mu It's still stuck in the boot loop. Aug 14 21:20:44 interestingly it shows 1 GiB RAM Aug 14 21:26:30 Blub__, that happens when it didn't properly detect the nand. Aug 14 21:28:20 so if it was my board... at this point i'd patch u-boot's boot script to run : [nand.erase chip] just to clean out the nand contents that seem to be causing this.. Aug 14 21:30:34 this means building u-boot from source? Aug 14 21:30:56 or adding a script file to the boot partition? Aug 14 21:32:42 yeap... Aug 14 21:33:14 why not just use the userbutton? Aug 14 21:33:59 checkout the pastebin's... it's not reacting to that.. Aug 14 21:34:12 it is held down? Aug 14 21:34:19 then the SD card is invalid Aug 14 21:34:49 I have three different cards here Aug 14 21:34:52 except, it's loading MLO/u-boot.img from mmc:... Blub__ are you holding it down? Aug 14 21:35:00 hmmm? Aug 14 21:35:18 it is? Aug 14 21:35:23 what's with this - Loading u-boot.bin from nand Aug 14 21:36:25 the previous one: http://pastebin.com/011mSYS5 (it's loading my MLO/u-boot.img from the SD) Aug 14 21:36:25 it just reboots after loading from the card Aug 14 21:36:37 ahhhh Aug 14 21:37:21 it's very odd, seems something is stuck in the bootargs.. Aug 14 21:38:00 it isn't getting that far Aug 14 21:38:00 this can be. I used it last time for a school project Aug 14 21:38:16 it is picking up a bum config and going into the weeds, AFAICT Aug 14 21:38:17 and we tried an Android image Aug 14 22:14:21 <__butch__> Hi y'all. Silly question. My BBB has decided that it's USB interface to my Mac is going to take today off. Aug 14 22:14:51 <__butch__> Yesterday, I could plug it in via USB and the USB network interface configured properly and I could ssh to it, etc. Aug 14 22:14:54 <__butch__> Today, not so much. Aug 14 22:15:10 <__butch__> Nothing, other than the day and a reboot of both the BBB and the Mac, have changed. Aug 14 22:15:12 <__butch__> Thoughts? Aug 14 22:15:28 <__butch__> I'm serial'ed into it, and I can see that the BBB has the proper IP address. Aug 14 22:15:57 when it's connected to the mac, check dmesg and such Aug 14 22:19:07 <__butch__> tawr: don't see anything obvious Aug 14 22:19:49 and on the mac side? when it's connected via usb, ifconfig shows usb0 up with the right ip and all? Aug 14 22:21:24 <__butch__> ifconfig doesn't show usb0 Aug 14 22:21:33 <__butch__> I've reinstalled the drivers and rebooted, which didn't help. Aug 14 22:21:42 <__butch__> I've tried two different USB cables, which didn't help. Aug 14 22:21:54 <__butch__> I'm powered by both USB and 5V Aug 14 22:22:01 <__butch__> Doesn't help Aug 14 22:22:45 <__butch__> No messages in dmesg on the BBB when I plug in USB, Aug 14 22:23:01 <__butch__> Nothing in console (syslog, etc.) either. Aug 14 22:34:42 <__butch__> Any other ideas? Aug 14 22:45:36 <__butch__> I just tried the same USB cable, SD card, Mac, with a different BBB and it worked fine. Aug 14 22:46:21 <__butch__> Does that jog any brain cells for anyone? Aug 14 22:48:32 <__butch__> Plugged the old one back in, same problem. Aug 14 22:48:45 <__butch__> Did the USB port somehow get smoked? Aug 14 22:49:08 <__butch__> Or is there something far more sinister going on here? :-( Aug 15 01:32:20 i just got my BBB, installed the driver, connected to my pc(win7) via usb. and try to connect to server 192.168.7.2 but nothing happens. the led lights are blinking away. i am not sure if my pc even detects the BBB? how do i check if the pc is connected to the BBB? Aug 15 01:32:46 and it's BBB Rev C. Aug 15 01:34:35 lifosuck, Aug 15 01:34:44 did you follow the directions on the site? Aug 15 01:34:52 or just decide to plug it in and see if itm agically worked Aug 15 01:35:00 followed the site of course Aug 15 01:35:53 did you install the windows drivers ? Aug 15 01:35:55 yup Aug 15 01:35:59 control panel Aug 15 01:36:03 system, device manager Aug 15 01:36:27 i am in it, i can't find beaglebone Aug 15 01:36:33 is the bbb being shipped with the image that does not force you to eject it as a drive? Aug 15 01:36:48 i don't see it as a drive either Aug 15 01:37:04 if i unplug it, nothing in the device manager changes Aug 15 01:37:07 if i plug it in Aug 15 01:37:10 nothing happens Aug 15 01:37:11 Did you do the all too famous windows reboot? Aug 15 01:37:17 twice Aug 15 01:37:21 went into linux mint Aug 15 01:37:27 and didn't see it either Aug 15 01:37:52 try a different cable Aug 15 01:38:08 What USB are you using? Try a different port.. if you're using USB3, try a USB2 Aug 15 01:38:11 or possible, go ahead and UPDATE the BBB with the newest debian image Aug 15 01:38:13 using the microsd card Aug 15 01:38:23 using usb2, tried 3 ports already Aug 15 01:38:31 i will try another pc Aug 15 01:38:49 sadly i don't have msd card, so i am hoping the image on it works Aug 15 01:39:33 What LED's flash on the bbb when you plug it in? Aug 15 01:39:58 first, 4 full led, then now it's 2nd and 4th Aug 15 01:54:46 any luck lifosuck Aug 15 01:55:31 still trying on my laptop Aug 15 01:55:38 restarting for the 3rd time Aug 15 01:55:47 if you're still having issues, i would boot into mint and grab the dmesg after the USB connection Aug 15 01:56:00 okay Aug 15 01:56:11 try a different cable too Aug 15 01:56:19 you're plugging into the MINI usb connection on the BBB right? Aug 15 01:56:31 and it's being powered over USB as well? Aug 15 01:56:49 yes Aug 15 01:56:51 that's right Aug 15 01:57:52 would you happen to be using an un-powered hub? Aug 15 01:58:07 it's directly from my laptop Aug 15 01:58:13 from usb2 port Aug 15 01:58:44 so when you plug it in, it actually boots up and is powered via the usb connection Aug 15 01:58:59 but nothing shows up on the device manager, no sound from "new usb device" from windows, etc? Aug 15 01:59:04 nope Aug 15 01:59:10 and you've tried different usb cables already? Aug 15 01:59:16 nothing happens when i plug it in or unplug it Aug 15 01:59:26 i'd say re-install the drivers on the windows computer Aug 15 01:59:43 tawr, it should come up in mint though Aug 15 01:59:52 then plug the bbb in. give it a minute to boot up (60 seconds). press the power switch and let it turn itself off. then press the power switch to turn it back on (without touching the cable) Aug 15 01:59:57 Decessus, i agree Aug 15 02:03:02 hmm nothing works, i am gonna boot in mint, brb. Aug 15 02:09:34 wb Aug 15 02:10:12 thanks, i am doing dmesg | grep -i tty but it doesn't seem to show anything related to beaglebone Aug 15 02:11:56 and dmesg doesn't show it either Aug 15 02:12:03 might be the hardware then? **** ENDING LOGGING AT Fri Aug 15 03:00:00 2014
