in an embedded linux class i was teaching last week, the students were all using beagle xMs (rev C), and we decided to experiment with playing with the LEDs from user space.
using the LED files under /sys/class/leds worked fine -- changing the brightness, trigger and so on. but using this article as a basis: http://makezine.com/2009/02/03/blinking-leds-with-the-beagle-board/ we simply couldn't control the very same LED via gpio. we followed the article, tried changing the LED trigger and so on, but nothing worked. can anyone with a BB xM (Rev C) verify whether or not that article works for them? let me know which LED you pick, the GPIO pin number you use, whether you need to change the trigger, etc. i'm sure i'm missing something trivial, i'd just like to figure out what it is. p.s. using robert nelson's debian build here: https://rcn-ee.net/deb/rootfs/wheezy/debian-7.3-console-armhf-2014-01-24.tar.xz rday -- ======================================================================== Robert P.
