i.MX 8M Plus PWM low power mode

[maffan]

Hello,

I’m working on a system where we’d like to keep one of the PWM modules active during low-power (sleep) mode. The reference manual states that the module "can be programmed to be active in low-power mode," but I notice that the PWM signal always drops to zero when the system enters sleep.

Could this behavior be resolved by modifying the PWM driver or the ATF (Arm Trusted Firmware), or is there another approach I should consider?

Thank you for your help!

Kind regards,
Marcus

Hello,

Whit the ATF need to be totally power off the pwm, however if you want to modify this situation you have the open source code and can do the proper modification, but you are by you own.
