Looping Thierry who maintains the PWM subsystem. I'm thinking your PWM driver is https://lkml.org/lkml/2013/9/24/776. Is it correct? However, I can't find any pin control for the PWM output. Just clock control and internal register access, PWM_EN and PWM_DIS. Is the pin controlled via the registers? Best regards, Milo On 09/26/2013 05:00 AM, Alexandre Belloni wrote:
Hi, I'm using leds-pwm on an atmel sama5d31 based board. I have one question/issue. In __led_pwm_set(), if the duty cycle is 0, pwm_disable() is called. This won't work fine on that platform. What happens is that pwm_config() correctly sets the duty cycle to 0 which is behaving correctly with that controller (and in my case, putting the line low). But the call to pwm_disable() is making the pwm controller release the line and then it is set to high. I've tried various configurations, like configuring a pull-down on the pin but I still observe the same behavior. For now, I have a workaround in atmel-pwm (I activate the output overdrive when duty cycle is 0). But I believe, we should find another way to do that. Any input is appreciated. Regards,
