I have a board Emtrion dimm mx6, with imx6q freescale processor.
When I bought the board there was no pwm initialized at boot. I booted my pwm with the command imx_add_pwm (1).
In my board three port pin (GPIO4/5/6) can be used as pwm outputs (GPIO4=PWM1 in my case)
I can not see my signal on my GPIO4. Emtrion told me that it was a problem multiplexing.
What should I do to make my gpio mode pwm.
