**** BEGIN LOGGING AT Sun Aug 23 02:59:58 2015 Aug 23 08:13:33 I finally resized the partition using gparted Aug 23 08:14:03 I have no idea what was failling Aug 23 09:58:01 I'm trying to get BBB to run a C program that interfaces with PRU. I've compiled the device source tree into EBB-GPIO-Example.dtbo and copied it to /lib/firmware. Presumably I need to tell the C program that it's the one to be used? Aug 23 10:00:23 you'll need to load the overlay to a slot Aug 23 10:01:04 Oh yes - can you remind me how you do that? Aug 23 10:01:11 e.g. echo BB-BONE-PRU > /sys/devices/bone.capemgr/slots Aug 23 10:02:19 Thanks, It's all so obvious I'm amazed I have to ask :) Not! Aug 23 10:02:26 np Aug 23 14:52:40 hi. i accidently removed the emmc paritions on my beaglebone black using fdisk. i still have a sdcard with a bootable ubuntu 14.04 installed (its working on my other beaglebone black), but the first beaglebone black doesnt boot at all (i pressed the user s2 button on power connect). only the power led is on, usb serial terminal shows "CCC". is the device damaged or is there a way to restore it? Aug 23 14:55:46 brummel444: make sure to press and hold s2 before connecting power Aug 23 14:56:21 tbr: i did, nothing happens Aug 23 14:56:53 CCC means ROM-BL didn't find a MLO on storage and is waiting for a SPL via serial Aug 23 14:57:02 aka board is just fine Aug 23 14:57:29 if nothing happens, then something is wrong with the card. write a fresh image to the card. Aug 23 15:00:13 tbr: i tired to boot via serial, but after the spl is transferred, i get: "SPL: Unsupported Boot Device". the sdcard with the image is currently running on my second beaglebone, i think it should be fine Aug 23 15:00:50 hrm Aug 23 15:02:07 tbr: do you know where i can get a u-boot / spl binary? maybe s.th went wrong during compiling (i tried several times) Aug 23 15:02:46 sadly no. I never used SPL. Aug 23 15:03:19 I wonder why the card doesn't boot Aug 23 15:03:34 tbr: should the bbb boot from the sdcard even with no u-boot on emmc? Aug 23 15:03:35 do you get any serial output? Aug 23 15:03:54 yes, serial output is only C's "CCCCCCCCCC...." Aug 23 15:04:07 yes, that's what S2 is for. holding it down makes it look for MLO on the SD instead of emmc Aug 23 15:04:19 S2 closes one of the SYS_ID lines Aug 23 15:04:57 and those only get read on power up, not on reboot and not on reset Aug 23 15:06:09 I'd recommend to try a different card with a recent official bb.org debian image Aug 23 15:06:40 tbr: i see, thats why reboot works from sdcard. ok, ill try that.. i also tried the emmc flasher image (didnt work) Aug 23 15:07:07 the flasher image should boot Aug 23 15:08:11 you should visually inspect if your sdcard slot is broken or such Aug 23 15:11:35 tbr: btw, is it possible to switch between sd and emmc on a reboot? Aug 23 15:12:21 don't remember if you can mess with the sys-id registers on runtime, possibly Aug 23 15:12:38 the TRM should know Aug 23 16:19:00 ey Aug 23 16:19:41 anybody knows why I can see no hard disck attached to my usb switch from my BBB? Aug 23 17:50:15 * nerdboy packing up a bunch of crap to use for yocto class Aug 23 17:53:28 denix: => http://sbhackerspace.com/yocto-openembedded-boot-camp/ Aug 23 18:09:13 nerdboy: nice! Aug 23 19:35:44 Is anyone here able to help with this: < http://derekmolloy.ie/beaglebone/qt-with-embedded-linux-on-the-beaglebone/ >? Aug 23 19:50:52 What does this happen:"# opkg update -bash: opkg: command not found"? Aug 23 20:27:13 it means opkg wasn't found as a executable file or batch file. Aug 23 21:58:55 Whydoes this happen:"# opkg update -bash: opkg: command not found"? Aug 23 22:01:57 it says it didn't find the command which likely means the command isn't in the executable path or doesn't exist on the system. perhaps you should look for opkg and what it does? **** ENDING LOGGING AT Mon Aug 24 02:59:59 2015
