**** BEGIN LOGGING AT Wed Jul 30 03:00:01 2014 Jul 30 03:35:27 ARRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGGGGGGGGGGG Jul 30 05:34:38 Good morning. Have someone got a list over known good microsd-cards for omap 3530? Jul 30 05:37:30 no Jul 30 05:38:40 I think the list of known bad would be shorter Jul 30 05:40:43 my sandisk 1GB locks it up hard (it's around 3 years old, no idea the exact model) and works find on a windows7 mach Jul 30 05:40:55 ^find^fine Jul 30 05:41:21 we've used sandisk extreme 16gb, which has served us well. in early 2013 they replaced that card with something faster, and that gives us issues. Jul 30 05:41:41 so I'm looking for alternatives Jul 30 05:42:22 tasslehoff: from when we worked with omap3, I dont remember that we had problems with specific cards Jul 30 05:42:39 but of course it could be that back then all cards were too slow compared to today Jul 30 05:42:53 av500: that was probably before march 2013 :) Jul 30 05:42:57 Hi Jul 30 05:42:58 for sure Jul 30 05:43:01 how to use pwm? Jul 30 05:43:03 in pru Jul 30 05:43:11 pru has no PWM Jul 30 05:43:20 I am trying this www.embedded-things.com/bbb/wireless-servo-control-part-3-pwm-servo-control-with-the-bbb-pru/l Jul 30 05:43:27 but its outdated Jul 30 05:44:05 av500, can be used to generate one right? Jul 30 05:44:23 av500: it is the exact same issue as in http://gumstix.8.x6.nabble.com/MicroSD-I-O-Errors-td4968025.html, and tests on different sd cards show that it is the ones from post-march-2013 that don't work. Jul 30 05:44:28 mkad: right Jul 30 05:44:50 tasslehoff: well, when TI shut down OMAP, things went downhill Jul 30 05:44:59 but, I'm keen on finding a working one instead of hunting for patches to backport to 2.6.39 Jul 30 05:45:33 av500, I read cpu running OS is unrelible to generate stable PWM signal, so author of post used PRU, host is calculating delay and passing it to PRU which just generates signal Jul 30 05:45:41 av500, however post is outdated Jul 30 05:45:58 yes, thats a good use case for the PRU Jul 30 05:46:05 mkad: why outdated? Jul 30 05:46:06 av500, so I was wondering if this is somehow included now somewhere Jul 30 05:46:13 included? Jul 30 05:46:28 well script fails to download TI link Jul 30 05:46:35 wget http://e2e.ti.com/cfs-file.ashx/__key/telligent-evolution-components-attachments/00-791-00-00-00-23-97-35/attachments.tar.gz Jul 30 05:46:35 tar -xzf attachments.tar.gz Jul 30 05:46:36 av500: not a surprise. issues that would have been fixed before are not, I suspect. Jul 30 05:46:38 this fails Jul 30 05:47:56 av500, I downloaded file with firefox and tried manualy to patch pru package Jul 30 05:48:01 but patches fail Jul 30 05:48:22 Hunk #1 FAILED at 98. Jul 30 05:48:22 Hunk #2 FAILED at 112. Jul 30 05:48:22 Hunk #3 FAILED at 652. Jul 30 05:49:03 and than I need modified patched dtc... :| Jul 30 05:49:27 this looks like a lot of steps somewhere in 2013... Jul 30 05:49:49 yeah well, its the fate of blog posts Jul 30 05:49:57 they stay the same while the world moves on Jul 30 05:50:06 but there are many links to be found about using the PRU Jul 30 05:50:11 hmm ok Jul 30 05:50:17 I will try something else thank Jul 30 06:02:27 is there any public PRU code available that uses the 28bit shift capture mode? Jul 30 06:03:04 couldn't get it to trigger capturing when I tried some time back. also found no code using that mode Jul 30 06:23:31 tasslehoff: what can I say, had your based your dev work on raspberry pi, you would not have these problems now Jul 30 06:24:09 :) Jul 30 08:26:46 av500, I try other source to run code on pru I get sig segv when uploading it Jul 30 08:26:59 av500, I tried this http://elinux.org/ECE497_BeagleBone_PRU Jul 30 08:27:14 debian@arm:~/AM335x_PRU_BeagleBone/GPIO_PWM_PRU/bin$ ./blinker Jul 30 08:27:14 Segmentation fault Jul 30 08:28:29 it fails on prussdrv_pruintc_init() Jul 30 08:30:44 I am trying to build a device tree blob. In the source i have an #include "x.dtsi" however in an old version I had a /include/ "x.dtsi" now the device tree compiler complains about #include line. what am i doing wrong? Jul 30 08:38:34 hmm manual does not mention to enable pru Jul 30 08:55:42 Hi, I have installed on an 8gb sd card the software provided by this website. then I have tried to do apt-get update but it says "no space left on device" I dont think it needs 8gb for an image. what can i do to expand and use more of my sd card? Jul 30 09:19:38 I give up Jul 30 09:19:51 is there any official wiki with howto use PRU Jul 30 09:19:52 ? Jul 30 09:20:00 nothing I find works Jul 30 09:20:07 segfaults etc.. no result Jul 30 09:24:14 also leds are blinking for no reason after booting already Jul 30 09:24:18 why? Jul 30 09:30:35 mkad: modprobe uio_pruss ? Jul 30 09:39:03 maquefel, yah yah but my leds are blinking like crazy for no reason after booting so I dont know if example does anything Jul 30 09:41:45 mkad: are your LEDs under Linux control? Jul 30 09:44:38 Humpelst1lzchen, what do you mean? Jul 30 09:44:49 Humpelst1lzchen, No i dont use them Jul 30 09:45:04 Humpelst1lzchen, I just booted from sd card with Debian Jul 30 09:45:10 and they blink like crazy Jul 30 09:45:13 for no reason Jul 30 09:47:17 mkad: I assume thats a "yes" Jul 30 09:48:18 mkad: You might wand to remove the LEDs from Linux or disable their trigger Jul 30 09:48:31 mkad: check /sys/class/leds Jul 30 09:50:18 Humpelst1lzchen, I might try that Jul 30 09:50:24 Humpelst1lzchen, thx Jul 30 09:51:09 Humpelst1lzchen, can this be set on boot somehow? Jul 30 09:52:05 mkad: you can do the echo none /sys/class/leds/.../trigger on boot yes but the prefered way for you is probably to remove the led from the devicetree Jul 30 09:53:17 Humpelst1lzchen, I want to control it with my own script Jul 30 09:53:25 dunno why it blinks Jul 30 09:53:27 https://www.perturb.org/display/1127_BeagleBone_Black__USR_Leds.html Jul 30 09:53:31 probably heartbeat Jul 30 09:53:48 mkad: do a cat on the triggerfile, it will tell you why Jul 30 09:55:10 ok Jul 30 09:55:21 I turned off heartbeat Jul 30 09:55:52 now one led blinks very fast others are off.. and I think its the led I tried to control with pru Jul 30 09:55:57 so looks all is fine Jul 30 09:56:01 Humpelst1lzchen, thanks Jul 30 10:08:00 Humpelst1lzchen, another problem I dont see all partitions Jul 30 10:09:02 Humpelst1lzchen, http://paste.debian.net/112618/ Jul 30 10:17:31 mount /dev/mmcblk1p1 /mnt/ Jul 30 10:17:31 mount: special device /dev/mmcblk1p1 does not exist Jul 30 10:17:33 any help? Jul 30 10:19:27 mkad: mmcblk1p1 is not listed in /proc/partitions Jul 30 10:36:35 Hi all Jul 30 10:37:17 I have a new BBB Jul 30 10:37:30 because I need to install the Ubuntu on it Jul 30 10:37:37 show I follow this instruction Jul 30 10:37:38 http://www.armhf.com/boards/beaglebone-black/bbb-sd-install/ Jul 30 10:38:05 when I finished the step g "Finally, commit the changes by selecting w to ‘write’ the partition table and exit fdisk" Jul 30 10:38:12 I unplug the usb cable Jul 30 10:38:50 I plug the cable again but the board is not starting anymore Jul 30 10:39:23 can someone help me recover it as the original state ? Jul 30 10:39:26 thanks a million Jul 30 10:41:03 i want help in booting bb-xm angstromimage any one there? Jul 30 13:02:36 Hi Jul 30 13:02:49 anyone use Xport to connect on BeagleBone Black UART0 ? Jul 30 13:03:07 I have a strange echo problem on UART0 of BBB Jul 30 13:09:28 explain Jul 30 13:12:20 hi Jul 30 13:12:39 I connect a Lantronix XPort to BBB UART0 Jul 30 13:13:38 lol Jul 30 14:19:19 Humpelst1lzchen, yes its not Jul 30 14:19:28 Humpelst1lzchen, do you know how to mount it? Jul 30 17:25:15 What is the max sampling rate of the on board ADC? Jul 30 18:14:01 > Jul 30 18:14:23 <_av500_> Jul 30 18:33:52 Hello - can someone tell me a way to compile bbb pru stuff on windows using eclipse? Jul 30 19:23:07 hello, I have an issue with beaglebone black. I am trying to connect a webcam and stream. but whenever I run my node code, stream stops and I lose connectivity on the webcam. I have to restart the device to get the usbwebcam work again. I have I/o error on webcam whenever I run my node script. what might be wrong? Jul 30 19:39:38 trevize why you need node? better user gstreamer Jul 30 19:41:49 beacuse I'd like to show the webcam in a webpage Jul 30 19:43:04 but as you see the node stuff whatever it uses to prepare a stream is not reliable Jul 30 19:44:28 node wont run the stream, I use mjpegstreamer to run a stream Jul 30 19:44:41 ieekks Jul 30 19:44:43 * tbr would probably use gstreamer and do a low framerate WebM stream Jul 30 19:44:49 node just runs the code to start/stop the stream and it is working fine Jul 30 19:44:51 mjpegstreamer is utter shit Jul 30 19:44:56 and put that in a
