**** BEGIN LOGGING AT Thu Aug 13 02:59:59 2015 Aug 13 05:45:09 hi, i am building a cape, and am going to make extensive use of i2c1 on pins 17 and 18. It seem silly to reserve the entire bus just for my cape, is there some convention to just reserve the addresses I want to use, check to see if i2c1 is already initialized and still initialize i2c1 if it hasn't been done already? Aug 13 10:52:33 hi, quik question, I backed up an 8GB image of a working sdcard from a rev B beagle. Then I resized the image to fit a 4GB. It boots ok in a rev C board, but not in a rev B. Any sugestions ? Aug 13 10:53:19 gremmlins Aug 13 10:53:38 and missing boot console output Aug 13 11:01:20 i backed up a rev B memory card into an 8GB image. The reduced the image to 4GB with mini partition tool and a 4GB pen drive. And burnet the 4GB image again to the sd card. It boots fine in revC board, but not at all in rev B. in rev B it just boots from eMMC Aug 13 11:01:55 any ideas why? I am puting now the 8GB image to see if it still works Aug 13 11:07:49 Hi, I backed up a rev B memory card into an 8GB image. Then reduced the image to 4GB with mini partition tool and a 4GB pen drive. And burnt the 4GB image again to the sd card. It boots fine in revC board, but not at all in rev B. in rev B it just boots from eMMC Nny ideas why? I am puting now the 8GB image to see if it still works Aug 13 11:20:23 mikemx55: please, do not ask a 4th time in 15 minutes, ok? Aug 13 13:23:37 Does anyone here have any experience with running the Beaglebone Black(industrial variant) in sub-0 temperatures? Aug 13 13:27:38 hello. I'm connecting to my bbb through the j1 console. when it boots I get an endless stream of 'C's, one every second. I think a copy from sd card to emmc failed. when I try to boot of the sd i get the same output. Aug 13 13:37:16 okay, I got it to boot, there is a formatted 8gb sd card in but on the console I get : 'Card did not respond to voltage select - No micro SD car found, setting mmcdev to 1' Aug 13 13:37:19 abferm: you mean bluesteel, I guess. I'd recommend to test it, thoroughly. ;) Aug 13 13:37:25 but the card is in there. Aug 13 13:44:54 tbr: nope, at least I don't think so. The company I work for ordered some Beaglebone Blacks with industrial temperature range components rather than the commercial grade ones directly from Circuit Co. Aug 13 13:45:23 abferm: ah, ok, yet something different Aug 13 13:49:24 tbr: anyway, I was running them at -30 C and on a power cycle they could not find their ethernet. Aug 13 13:50:01 I double checked all the part numbers and everything is rated down to -40 C.

Aug 13 14:02:39 abferm: I remember this being discussed recently here. you could check logs with a search engine. Also you could poke RCN. He should know. Aug 13 14:06:26 Okay... I got it to boot from the sd and edited the uEnv.txt to get it to flash the emmc Aug 13 14:06:55 and I got a kernel panic hung task during the rsync Aug 13 14:07:18 and I got a kernel panic hung task during the 'rsync /boot/uboot/ -> /tmp/boot' and I pooched? Aug 13 14:08:11 the blue leds stopped moving... Aug 13 14:43:46 I found out why my emmc flash keeps failing Aug 13 14:44:47 rsync / -> /tmp/rootfs keeps failing because there is no space left on device. Aug 13 14:45:32 the sd card is an 8gb card. is that the cause of the issue? do i need to find a 4gb card? Aug 13 14:46:05 if i resize the sd card boot partition to 4gb will that help? Aug 13 14:47:51 your boot partition is 4gb? Aug 13 14:47:59 it seems like it's failing when writing files, it's an rsync not block copy. how can it be running out of space? Aug 13 14:49:16 crap. are there different rev versions of bbb with different emmc sizes? Aug 13 14:49:28 goge: is your BBB RevC? Aug 13 14:49:57 goge: only RevC has a 4GB eMMC. previous versions are 2GB and there are flasher images that fit that Aug 13 14:49:59 I bought it years ago and dug it out of a bin this morning. what's the fastest way to check? Aug 13 14:50:15 years, then it's not RevC Aug 13 14:50:15 ya. that would make sense Aug 13 14:50:31 probably A5 or A6 (check on the side of the ports) Aug 13 14:51:03 where can I find a 2gb flasher image of debian? Aug 13 14:51:05 https://rcn-ee.com/rootfs/2015-07-08/flasher/ Aug 13 14:51:24 thanks! Aug 13 14:51:26 np Aug 13 15:24:56 just noticed we have a c compiler for the PRU now. that must be insanely helpful. last i checked it was all aSM Aug 13 15:30:41 goge: where is said C compiler? Aug 13 15:33:16 http://elinux.org/Ti_AM33XX_PRUSSv2#C_Compiler Aug 13 15:42:41 Hi, where can i find a defconfig file for the beaglebone black ? mainline 4.x /arch/arm/configs/ doesn't show any defconfig related to BBB Aug 13 15:43:08 PacoDu, "mainline" omap2plus is a good starting place..... Aug 13 15:44:33 Ok thanks :) ! Aug 13 15:46:54 rcn-ee : i'm actually trying to customize the kernel deployed by your script on https://github.com/RobertCNelson/bb-kernel, so after ./build_kernel.sh, using make ARCH=arm menuconfig omap2plus_defconfig is the right way ? Aug 13 15:47:33 PacoDu, just edit "patches/defconfig" and it'll pull that config in for ./build_kernel.sh Aug 13 15:48:37 so for omap2plus_defcofnig, just cp patches/ref_omap2_plus_defconfig patches/defconfig ; ./build_kernel.sh Aug 13 15:52:25 Hum ok, i'm looking for building a kernel using PREEMPT, reset default pinmux at kernel boot time, custom driver.. i can see a defconfig-bone in the patches/ dir, so which one should i take to take a proper start on configuring my kernel ? the actual defconfig, omap2plus, defconfig-bone ? Aug 13 15:52:59 i need to custom the kernel conf for FTRACE, kernel debug, PREEMPT .... Aug 13 15:57:38 PacoDu, "patches/defconfig" is the default one used by the scripts.. so if you want to add remove things edit that.. Aug 13 15:57:52 (when menuconfig pops up, all changes are saved to patches/defconfig) Aug 13 15:59:34 thanks rcn-ee! Aug 13 16:00:15 * jkridner has been hacking at 2GB images today a bit trying to find simple ways to prune. Aug 13 16:00:18 not so easy. Aug 13 16:00:28 but when i run make menuconfig on ./bb-kernel/KERNEL the default arch is set to x86_64 ... it's not loading your defconfig Aug 13 16:00:50 what am i doing wrong Aug 13 16:03:02 PacoDu, ARCH=arm if you run manually.. Aug 13 16:03:33 ye but this is not loading the defconfig by using make menuconfig ??? Aug 13 16:03:58 PacoDu, well yeah... run "./build_kernel.sh" otherwise it's completely up to you... Aug 13 16:04:28 "./tools/rebuild.sh" also works, once you ran "./build_kernel.sh"... Aug 13 16:05:02 ok arch is not saved in the defconfig that's why it's not loading the arch using make menuconfig ? Aug 13 16:05:14 Thanks a lot for your time ! ;) Aug 13 17:30:12 and I thought it was global warming... Aug 13 18:43:03 Hi guys!! Aug 13 18:43:36 My name is Romy Bompart, I am trying to find the way to drive my Color TFT Aug 13 19:03:27 question: I'm running a BBB with kernel 4.1.1-ti-r2. I'm trying to compile a simple hello world kernel module, essentially following the link here: http://dumb-looks-free.blogspot.ca/2014/06/beaglebone-black-bbb-kernal-headers.html Aug 13 19:03:46 my trouble is that apparently there are no kernel headers for my kernel release. Aug 13 19:04:07 My question is how can I go about getting/generating these required files so that I can build a kernel module? Aug 13 19:04:56 sounds like you need to install the kernel header package with apt-get Aug 13 19:05:21 linux-headers-??? Aug 13 19:05:35 search using apt-cache search linux-headers-$(uname -r) Aug 13 19:05:52 or install same way Aug 13 19:06:03 sudo apt-get install linux-headers-$(uname -r) Aug 13 19:06:41 running the apt-cache search doesn't return any results Aug 13 19:07:12 where did you get a 4.1 kernel? maybe they have the headers there too Aug 13 19:07:19 sorry, I forgot to mention that I'm running ubuntu 14.04 Aug 13 19:08:35 I got the kernel in a flasher file from Robert C Nelson from the website here: http://elinux.org/Beagleboard:Ubuntu_On_BeagleBone_Black Aug 13 19:11:30 you should be able to get the headers thru dpkg or apt-get I would think, just have to know the correct package name Aug 13 19:12:07 but I could be wrong Aug 13 19:12:17 same results with the apt-get install linux-headers-$(uname -r), it doesn't work Aug 13 19:12:51 dpkg -s kernel-headers Aug 13 19:13:41 is there some way I could maybe install an older version of the headers (4.0 or something) and have it still work? Aug 13 19:13:57 I wouldn't suggest it Aug 13 19:14:02 or 4.1.0 Aug 13 19:14:15 darn Aug 13 19:14:52 sudo apt-get install linux-headers-$(uname -r) Aug 13 19:14:55 that doesn't work? Aug 13 19:17:19 correct Aug 13 19:17:22 works for my debian install Aug 13 19:17:27 3.8 kernel Aug 13 19:17:39 it tells me E: Unable to locate package linux-headers-4.1.1-ti-r2 Aug 13 19:18:22 try dpkg-query -s linux-headers-$(uname -r) Aug 13 19:18:51 see what is says, it might need -generic at the end Aug 13 19:23:38 it says it is not installed and no information is available Aug 13 19:24:08 but I just got an email back from Robert Nelson telling me to update my kernel version and grab the new kernel headers at the same time. Aug 13 19:24:15 I'll give that a shot and see what happens. Aug 13 19:37:51 I followed what Robert said and updated my Kernel, and I was able to compile my simple kernel module. Aug 13 19:38:02 thanks for your help, so It seems like I'm good to keep trucking away from here Aug 13 19:38:07 thanks for your help, I appreciate your time Aug 14 00:50:51 sigh...
