**** BEGIN LOGGING AT Wed Dec 25 02:59:59 2013 Dec 25 08:03:10 hi Dec 25 12:23:30 Hello guys.. is there any place I can download PSP kernel base precompiled sdcard images? Dec 25 17:17:08 Hi Guys, I tried many things, but I can't make PWM on my BBB to work via generic linux /sys/class/pwm interface . Did anyone have any luck with it? Dec 25 17:18:40 I can successfully export pwm devices 0-7 & write values into period_ns, duty_ns, run files, but I do not seem to get output on the pins Dec 25 17:20:50 I am running angstrom 3.8.13 on bbb Dec 25 17:24:40 anybody alive here? Dec 25 17:24:58 nope - all zombies Dec 25 17:25:13 :( I really need some help with the PWM Dec 25 17:25:32 sorry - don't know about that. Dec 25 17:26:03 np, I will wait and see if anyone else can help Dec 25 18:09:24 Merry Christmas where appropriate. Dec 25 18:11:17 Thanks Dec 25 18:50:23 where are you, PWM experts? :) Dec 25 18:54:16 Christmas - all the trolls are off playing in the real world Dec 25 18:56:19 kofe__: did you try one of the many video howto's or other sites to test or are you rolling your own? Dec 25 19:07:33 I have tried many things Dec 25 19:07:55 what videos specifically are you referring to Dec 25 19:09:58 http://digital-drive.com/?p=136 but many exist Dec 25 19:11:43 I need to control PWM via generic linux interface /sys/class/pwm Dec 25 19:12:48 all these videos including that one use a custom interface /sys/devices/ocp.*/pwm_test_* Dec 25 19:13:03 I think this is not portable Dec 25 19:18:07 what distro? Dec 25 19:18:12 angstrom Dec 25 19:18:23 I flashed the latest angstrom Dec 25 19:18:50 did you load your shield library for PWM? Dec 25 19:19:34 I loaded am33xx_pwm cape to enable PWM chips Dec 25 19:19:55 after that I can export pwm 0-7 using /sys/class/pwm/export Dec 25 19:23:20 kofe__: https://github.com/alexanderhiam/PyBBIO/issues/18 Dec 25 19:24:13 thank you, but I have seen those already Dec 25 19:24:53 so it sounds like /sys/class/pwm is deprecated Dec 25 19:25:42 where do you see that? Dec 25 19:25:53 I thought it is a standard linux interface Dec 25 19:27:41 Hey All! Dec 25 19:27:47 if you read that post I just put up. The first message talks about the issue. And a like to various libraries including node.js pwm lib and you can read the code. It does not talk to /sys/class/pwm when using am33xx_pwm. "maybe" it will work if not loaded Dec 25 19:27:59 https://github.com/jadonk/bonescript/blob/master/node_modules/bonescript/index.js line 544 Dec 25 19:28:00 Just got my BeagleBone Black!!! Love it!! Dec 25 19:29:18 Dr{Who} well that is exactly the problem Dec 25 19:29:22 kofe__: likely if am33xx_pwm is loaded it remaps everything Dec 25 19:29:41 I want to have a portable way to control PWM Dec 25 19:30:00 did you try unloading it? Dec 25 19:30:02 linux kernel documentation describes it as /sys/class/pwm Dec 25 19:30:19 if it is not loaded, there are not chips folders under /sys/class/pwm Dec 25 19:30:33 Wanted to know if anyone can point me in the right direction to resolve a problem. I wanted to install sqlite3 and node.js support for sqlite3. used opkg to install sqlite3 , but npm bombs when trying to install sqlite3 via "npm install sqlite3. Any ideas? Dec 25 19:31:31 it seems strange. You can control GPIO via /sys/class/gpio and you can not control PWM via /sys/class/pwm Dec 25 19:31:48 why the portable way to control GPIO works, but the portable way to control PWM does not Dec 25 19:33:14 here's a paste bin of the error messages: http://pastebin.com/eBn7WWZf Dec 25 19:33:31 kofe__: a question for the capemgr coders. Dec 25 19:33:42 Happy for any direction / pointers... Dec 25 19:34:53 uptownben https://github.com/joeferner/node-serialport2/issues/10 Dec 25 19:35:04 opkg install python-compiler Dec 25 19:35:07 try that first Dec 25 19:35:34 keel.. trying it Dec 25 19:35:39 *kewl Dec 25 19:42:27 kofe__: I am starting to think after reading a bit that it is a standard but it changed in 3.8 kernels Dec 25 20:43:28 My BeagleBone Black cuts the power to the USB host section when I connect a certain WiFi USB stick (presumably due to a current spike). Is there a way to re-enable the USB host without having to reboot the board? Dec 25 20:46:54 Strangely enough, the power is even cut when I bypass the switch IC (U8, a TPS2051) and current sensing resistor. Is there anything other than an over-current condition that can trigger disabling the power supply for the USB host port? Dec 25 21:23:23 <_av500_> anything in dmesg? Dec 25 21:45:58 hi every one, i am interested for BBB, but I am new user for it. I have just question to start quickly to learn everything about BBB. My question is : Is it possible to use BBB with 3 Capes at the same time, I mean, I need to use Inertial Navigation System Cape, BeagleBone HD Camera Cape and BeagleBone GPS/GPRS. If its possible that is my dream. Thank in advanced. Dec 25 21:48:02 _av500_: nope, i don't get any messages in dmesg, syslog or kern.log when i plug or unplug the wifi stick Dec 25 22:24:59 Underwater: not all capes support stacking, some do. you'll have to do some research if the pins conflict. Dec 25 23:07:24 So I my BBB is in that case from AdaFruit with the clear top. I went to open it (had to press the boot button for something), it's little bit of a pain to open, one of the edges of the clear plastic top got under my reset button and popped it right off the board!!! Dec 25 23:08:03 so my board no longer has a reset button, bad? Dec 25 23:08:25 unplug it Dec 25 23:08:50 it was unplugged when that happened, I was just trying to open the darn case... Dec 25 23:08:58 looks like everything still works Dec 25 23:09:14 was able to boot off the microSD card Dec 25 23:09:24 everything is running normally Dec 25 23:09:41 just wondering if I am going to need that reset button for anything Dec 25 23:09:57 I guess if I need to reset, i can just remove power, no? Dec 25 23:11:07 anyway, I may order another one just in case. Dec 25 23:11:58 yes removing power is akin to pushing the reset button Dec 25 23:12:04 Anyone know if there is a way to install RIAK on the BBB? I'd like to replicate that RIAK cluster experiment that was done with the Raspberry Pi. Dec 26 01:31:48 How do I get the beaglebone to boot up from SD card by default? Dec 26 01:49:07 zump: I believe you can do that by editing the uEnv.txt, but I don't know offhand what you should change Dec 26 01:50:06 zump: put an appropriate uEnv.txt file on the SD card... Dec 26 01:50:25 doesn't it check the uEnv on the eMMC first, though? Dec 26 01:50:26 zump: although if you want it to boot u-boot off the SD card, it's more involved. Dec 26 01:50:36 jpfau: not in my experience... Dec 26 01:51:12 jpfau: oh, you mean beaglebone, or beaglebone black? Dec 26 01:51:22 ah, http://ahsoftware.de/Beaglebone_Black_Boot_explained.svg indicates you're right Dec 26 01:52:07 hi Dec 26 02:00:24 Has anyone run into trouble using rtl8192cu wifi device? I get frequent dropouts **** ENDING LOGGING AT Thu Dec 26 02:59:59 2013
