BTW I can set GPIO12 as output:
$ cat /sys/devices/virtual/gpio/gpio12/direction out
But I cannot set it to
$ echo -n 1 > /sys/devices/virtual/gpio/gpio12/value && cat /sys/devices/virtual/gpio/gpio12/value 0
According to @Lazar-Demin (here: http://community.onion.io/topic/395/gpio-pin-12/4) GPIO27 is used for controlling the power LED and GPIO8 "is wacky". Didn't find some update on the GPIO8 (and GPIO12: http://community.onion.io/topic/578/issue-with-gpio-12/12) issue.
Any definitive update on the GPIO12 issue?
The GPIO8 might be used by the Omega as the power LED, see @Boken-Lin's answer here: https://community.onion.io/topic/360/0-0-5-b251-gpio8-vs-others/3. On the other hand, @Lazar-Demin wrote here: http://community.onion.io/topic/395/gpio-pin-12/4 that GPIO27 is used for controlling the power LED and that GPIO8 "is wacky".
