I was hoping to get some help with the imx53 loco board.
I can't get GPIO access to work.
I've set up the /sys/class sysfs support in the system using a new kernel.
With the ubuntu micro sd shipped with the qsb board (with newly flashed kernel)
I get permission denied when I try to echo 12 > /sys/class/gpio/export
With an ltib made rootfs and kernel
I get all the way through
echo 12 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio12/direction
echo 1 > /sys/class/gpio/gpio12/value
but the value doesn't change on the pin nor the actual file "value"
I can change the direction just fine, however the value still eludes me.
I've also tried this on different ports, still nothing works.
