I am using a new nano board. I have tried two fans across two card images (including latest) and I consistently get a permission denied error when executing:
sudo sh -c ‘echo 255 > /sys/devices/pwm-fan/target_pwm’
-bash: /sys/devices/pwm-fan/target_pwm’: Permission denied
And ‘sudo jetson_clocks’ does nothing, showing fan at 0.
Any suggestions would be sincerely appreciated.
