Hi folks,
I am working on an nRF52840-based custom board using nRF Connect SDK v3.2.4 and have observed an issue related to runtime power management and PWM.
Environment
- SoC: nRF52840
- NCS Version: v3.2.4
- PWM Instance: pwm0
- Use Case: Motor control
The motor control works as expected when runtime power management is disabled.
However, when I enable:
CONFIG_PM=y
CONFIG_PM_DEVICE=y
CONFIG_PM_DEVICE_RUNTIME=y
PWM0 no longer generates the expected output and the motor does not operate correctly.
Q: What is the recommended approach for keeping PWM active for continuous motor control while still benefiting from runtime power management ?
Thank you for your support.
