PWM on Neutis N5 developer board


(hamsterasu) #1

Hi all I have a problem with my Neutis N5 developer board when following the PWM example on https://docs.neutis.io/ .

I went to the /boot directory but there was no Env.txt file. So I created the file and added the lines:

loglevel=10
overlays=pwm

After that, i rebooted and when I run the command:

ls /sys/class/pwm/pwmchip0

I get this error:

cannot access ‘/sys/class/pwm/pwmchip0’: No such file or directory

Any help would be appreciated!
FYI,I was able to get the other examples like GPIO,UART working but not PWM, using the Env.txt.
