    Failed to configurate PWM to GPIO and output high

    LeCa_2156671

      Hi BCM,

       

           We want to set BCM20736 PWM0 output range: 1% to 100%.

           It's ok for PWM0 work between 1% to 99%

           To set PWM0 output high, I reset the PWM0, and then configurate the PWM0 to GPIO and finally output 1. The PWM0 would output high only when reset it during it's high duty, or it would output low no matter I call gpio_configurePin() to output 1.

       

           I checked Community, and find out the same issue as below, but without reply.

         

          Can't get 100% duty cycle from PWM

          How to properly disengage PWM ?

       

           Is this a bug of BCM20736 ?

           tks
