I want use lcd_bl_pwm0 to work, but can’t get pwm output on nano Module P3450 header pin32 under l4t 32.3.1.
had done steps:
- delete input config for the pin in gpio dtsi.
- config pin to pwm0 in pinmux dtsi.
- work with sysfs
- measure pin with scope.
But no pwm signal got just stay at 0.
Anyone could give some advices ?
