debug output looks identical here If I leave enable at 0 the output stays high, set enable to 1 and the output goes low and stays there regardless of any other changes I make. Even in this state, setting both period and duty_cycle to 50 gets me the 24MHz clock. Changing period back to 50000 now turns the 24MHz clock off and the output goes back to low [ 105.343411] JDS - sunxi_pwm_config duty 0 period 50000 [ 126.888438] JDS - sunxi_pwm_config duty 50 period 50000 [ 126.888462] JDS -
