**** BEGIN LOGGING AT Tue Aug 18 02:59:58 2015 Aug 18 06:34:09 hello folks :) Aug 18 06:35:22 bbb on debian here, trying to configure my wifi dongle Aug 18 06:35:33 it works fine when the ethernet is plugged in Aug 18 06:35:39 as soon as i unplug the cable, the wifi goes down Aug 18 06:35:51 will post my interfaces file momentarily Aug 18 06:36:56 https://gist.github.com/stormbytes/d0954a5febe5fb303b04 Aug 18 06:41:52 mhm, might make sense to look at logs Aug 18 06:42:27 also, do you have access to the serial console? Aug 18 06:42:53 serial console? Aug 18 06:42:56 ssh you mean? Aug 18 06:42:57 sure Aug 18 06:43:02 no, the debug UART Aug 18 06:43:20 not off hand no Aug 18 06:43:35 did you have a look at the interfaces file? Aug 18 06:43:43 i bet i screwed something up Aug 18 06:44:01 yes, one part is that you are assigning from the same subnet on both Aug 18 06:45:19 nice catch Aug 18 06:45:21 i'm really tired..... Aug 18 06:46:08 what's wlan1 ? Aug 18 06:46:21 on the rasp pi is wlan0 Aug 18 06:48:44 check with 'ip' or 'ifconfig' what the interface name is Aug 18 06:50:34 its wlan1 Aug 18 06:51:29 if you prefer wlan0 you'd need to check the relevant udev rules file Aug 18 06:51:43 no that's fine, i just want it to work :) Aug 18 06:51:46 on the rpi this was a synch Aug 18 10:31:29 Hi, i'm using u-boot 2015.07, i can't use the saveenv function ... return unknown command and it's not listed in help ... any idea ? Aug 18 10:37:43 Hi, I was following this tutorial (https://github.com/Teknoman117/beaglebot/tree/master/hcsr04-demo) for using an HCSR04 sonar in beaglebone black, but I ended up with mmc errors and now I'm unable even to boot... there was some big changes from kernel 3.8 to 3.14 relative to tree overlays ? Aug 18 10:38:55 I haven't used mmc GPIO pins Aug 18 10:40:08 the error i'm having exactly is: 7.165958] mmcblk0: error -84 transferring data, sector 2968, nr 8, cmd response 0x900, card status 0xb00 Aug 18 10:41:45 nyo: experience shows that in contrast to theory, the dts are still heavily version dependent and really should be recompiled for the specific kernel in use. Aug 18 10:42:22 so I should use the exact kernel of the tutorial.. ok thx Aug 18 10:42:50 but can I remove now this dts? Aug 18 10:57:35 so I have found out that if I remove the signals from pins of beagle,used in the tutorial, everything is fine.. Aug 18 12:38:03 Hi, i'm using u-boot 2015.07, i can't use the saveenv function ... return unknown command and it's not listed in help ... any idea ? Aug 18 12:38:46 PacoDu, you mean you can't do env save? Aug 18 12:38:53 pastebin? Aug 18 12:39:56 ye i can't save the env i've set for uboot :/ Aug 18 12:40:37 PacoDu, can you pastebin the output when you boot and try to do it? Aug 18 12:40:40 i'm setting ipaddr, serverip for example, and i would like to save them to not have to reenter them each time i'm testing my kernel Aug 18 12:41:00 PacoDu, where are you trying to save the env to? and on which beagle? Aug 18 12:41:36 it's juste in bootloader shell, cmd is unknown pastebin will not help you more ^^ Aug 18 12:42:21 PacoDu, take the output in your terminal window, copy it, go to pastebin, paste, post link here Aug 18 12:42:46 PacoDu, if you can't show what your problem is, it's hard to help you Aug 18 12:42:52 http://pastebin.com/zmhvRL25 Aug 18 12:43:12 PacoDu, when you type "help" do you see a command called "env"? Aug 18 12:43:19 PacoDu, if you type "help env" what does it say? Aug 18 12:44:35 PacoDu, it should show something like: http://pastebin.com/QeXSZXRY Aug 18 12:44:39 http://pastebin.com/VJCig9b8 Aug 18 12:44:42 yep it works Aug 18 12:44:56 ok thanks so cmd changed, it's env save now ? Aug 18 12:45:13 PacoDu, I think the whole "printenv" "saveenv" was getting depricated for a while now Aug 18 12:45:50 I don't have the save arg in help env >.< Aug 18 12:46:20 PacoDu, possibly your u-boot doesn't have the configuration or ability to save its env to a storage which it can access Aug 18 12:46:38 PacoDu, if you want always the same env, just set it in your uEnv.txt file Aug 18 12:47:05 often if you want to do "env save" then you are setting different things on different boards, like during a manufacturing run you put the serial number for each borad in the env Aug 18 12:47:18 PacoDu, if you are just doing development and want a static IP, just put it in the uEnv.txt Aug 18 12:47:39 Ok thanks for your time i'll try that Aug 18 12:48:01 Can you help me on device tree ? :) https://groups.google.com/forum/#!category-topic/beagleboard/advanced/YMhv3rQttsU Aug 18 12:48:39 I think i'm close but i'm missing something to get this work :/ Aug 18 12:50:40 PacoDu, please read http://devicetree.org first, it has very good information, also look at other dts files for examples of pin muxing, there's lots of good examples and the format is fairly straight forward once you've studied a few Aug 18 12:52:09 That's what i did, but i'm going to search again thank you ! Aug 18 15:15:45 Hi, I've rewrite my own am335x-boneblack.dts -> am335x-bone-custom.dts to modify default pinmux and disable hdmi, compiled my kernel, boot from TFTP... pins use by HDMI are now free but my pinmux doesn't apply ... can anyone help me ? I think i'm close to get this work but i'm propaly missing something ... :/ http://pastebin.com/2zKEffcQ Aug 18 16:57:58 PacoDu: In your first example (gpio3) I think 107 is wrong, should be 11 Aug 18 16:58:27 PacoDu: Try that and check /sys/kernel/debug/gpio Aug 18 18:34:31 I have a custom overlay that I want to override the stock one (for the BB-BONE-LCD7) I’ve created the dots, compiled the dtdo, move that (and overwrite the existing) to the /lib/firmware/. On reboots in dmsg I can see that its still loading the stock ver. In the uEnv.txt I added a capemgr.disable_partno= for the stock dtbo and enable for mine (with a different name) and it still uses the stock one. Is there Aug 18 18:34:32 something else I need to change? Aug 18 18:36:31 are you loading from the MLO on SD or eMMC? Aug 18 18:36:59 I’ve tried both the MicroSD and the eMMC. Same results. Aug 18 18:41:43 did you enable it in the same line as the disable? Aug 18 18:42:30 I disable the stock one 1st, right below that I enable the one I wanted. Aug 18 18:43:17 you have to add it in the same line Aug 18 18:43:56 back to back with no ‘,’ ? Aug 18 18:44:43 sorry, I cannot see how I did it, the Beaglebones are at work... Aug 18 18:44:55 i think without, try both Aug 18 18:45:18 I just them back to back, and rebooted. Same thing, It loads the default one. Aug 18 18:45:55 It’s like it completely ignoring the uEnv file Aug 18 18:46:31 where did you stick the uEnv.txt file? Aug 18 18:46:39 I got mine to boot with my device tree overlay, but I had to modify some other files and recompile, too Aug 18 18:46:52 I tried the top, middle and bottom. Same effect. Aug 18 18:48:24 btw capemgr does not work w/ all kernels Aug 18 18:50:01 The one thing I’ve tried was delete the one it keeps loading. But it still some loads it. Aug 18 18:50:12 *some how Aug 18 18:53:33 kernel version? Aug 18 18:53:58 Linux beaglebone 3.8.13-xenomai-r72 #1 Tue Apr 21 20:09:07 UTC 2015 armv7l GNU/Linux - MachineKit image Aug 18 18:54:20 3.8 should work Aug 18 18:55:49 I have a 3.8.13-bone50 with xenomai and a 3.8.13-bone70 both working Aug 18 19:11:35 MacGyverX: what folder is your uEnv.txt located in? maybe it is not running your file at all Aug 18 19:12:17 '/boot’ Aug 18 19:12:46 do you have a bootlog you can put on pastebin? Aug 18 19:22:40 if not, can you pastebin the results of `df` Aug 18 19:49:48 Hi, How can I burn angstrom image on my Beaglebone(white) ? Aug 18 19:51:54 thing: Put it on a microSD card. THe white bone has no eMMC onboard. Aug 18 19:53:19 is there a tool to copy compressed image on sd card ? Aug 18 19:53:25 I use linux OS Aug 18 19:54:31 Yes, uncompress it and use dd. Aug 18 19:54:42 There are tutorials online (check elinux.org) for this. Aug 18 21:35:25 Hi there, I was trying to debug BBB using a bluetooth adapter(HC06) and unfortunatly I couldn't Aug 18 21:36:08 Anyone have any experience on this ? Aug 18 21:36:44 I tried it using baudrate 115200 and 9600 as well Aug 18 21:37:09 If serial can then why bluetooth can't? Aug 19 00:54:28 hi all, this is my first beaglebone black, I've used dd to write the angstrom image http://debian.beagleboard.org/images/bone-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img.xz to a 16GB SD card but when I hold USER/BOOT it appears to have booted from /dev/mmcblk1p2 so I didn't edit /boot/uEnv.txt and rewrite the eMMC. Can someone help me get the BBB to boot from the SD card? Aug 19 01:02:36 I think it's booting from /dev/mmcblk1p2 because mount says "/dev/mmcblk1p2 on /media/rootfs type ext4" Aug 19 01:02:50 and "/dev/mmcblk0p1 on /media/BEAGLEBONE type vfat" Aug 19 01:03:55 I would think that the eMMC would be mmcblk0 and the SD card mmcblk1. Aug 19 01:04:03 SO that looks correct to me. Aug 19 01:07:30 Hi there, I was trying to debug BBB using a bluetooth adapter(HC06) and unfortunatly I couldn't Aug 19 01:07:36 I tried it using baudrate 115200 and 9600 as well Aug 19 01:07:39 If serial can then why bluetooth can't? Aug 19 01:08:03 agmlego, thanks! But /media/BEAGLEBONE/ID.txt ends with 2015-03-01. /boot/uboot/ID.txt ends with 2014-04-23. Also, if I remove the SD card and boot, mount says: "/dev/disk/by-uuid/813b///a0cc on / type ext4" and "/dev/mmcblk0p1on /boot/uboot type vfat" Aug 19 01:08:19 sorry, I didn't type the full uuid there Aug 19 01:10:04 aswin, can you post a pic of your setup? Aug 19 01:16:53 Its quite simple. The RX, TX and GND pin from the serial debug to HC-06 Bluetooth module and VDD from SYS_VDD pin Aug 19 01:25:30 aswin, you might have reversed RX and TX Aug 19 01:31:19 ok, agmlego, I apologize. Even if I don't hold down USER/BOOT, my BBB boots the 16GB SD card. I was also confused by the mount output: I saw "/dev/mmcblk1p2 on /media/rootfs" but I failed to observe the earlier line "/dev/mmcblk0p2 on / type ext4" Aug 19 01:31:36 so I can just edit uEnv.txt and reboot **** ENDING LOGGING AT Wed Aug 19 02:59:58 2015
