Tool/software: Linux
I'm building custom zImage for AM335x SoC using buildroot... The board is Beagle Bone Black compatible... I'm trying to add PRUSS support. Now I'm stuck at starting the PRU cores.
echo 'start' > /sys/class/remoteproc/remoteproc0/state returns:
[ 348.676722] remoteproc remoteproc0: Direct firmware load for /tmp/PRU_LED1.out failed with error -2
[ 348.686396] remoteproc remoteproc0: request_firmware failed: -2
[ 348.692661] remoteproc remoteproc0: Boot failed: -2
My device tree is attached to the post. I also tried to use am335x-boneblack-pru-adc.dtb with no luck. What can be the problem?
