Hello
Are there any tricks to getting the PWM output (GPIO_1_PWM2_PWMO) to output anything other than zero volts other than
echo 100 > /sys/devices/platform/mxc_pwm.1/pwm-backlight.0/backlight/pwm-backlight.0/brightness
?
The value is being reflected in the actual_brightness file but I get no output from the PWM pin.
Thanks
I've fixed this. It was a bug in the pwm driver distributed by Karo, which looks like it was broken during customisation. I don't think this bug exists in the mainline kernel.
I would look further into where it crept in but I've got to get back to productive stuff.
