OK, going straight to the point. The Jetson comes with PWM outputs. However when I try to access them, it tells me “Permission Denied”. I’m following The guidelines from http://elinux.org/Jetson/GPIO.
The guidelines says the following
Note: In the L4T kernel, the “soc0” directory component might not be there, and the PWM controller might be named something different like “pwm.0” or “pwm.1”. You might want to just run:
cd /sys find . –type d –name "pwmchip*"
However. When I try the command line cited above, the Jetsons gives the following
find: './kernel/debug': Permission denied
Any clue about what am I doing wrong? What am I missing?
