Changes any Peripheral pins configuration at runtime (after build and flash firmware)

[Siddharth Kachhia]

Hi,
I have gone through https://docs.zephyrproject.org/latest/hardware/pinctrl/index.html#pin-control doc and zephyr\samples\boards\nrf\dynamic_pinctrl sample code.

zephyr provides support of dynamic pinctrl at build time with define alternatives pins in overlay file.

I want to define alternatives pins in file at run time(not at build time) and configured that defined pins on next reboot. Fundamentally, I want build and flash firmware one time then after I can able to change pins without build and flash again.

Is this possible using dynamic pinctrl feature?

Any other way do this with zephyr dts files?

Hello Siddarth,

I believe the answer is no, but I will double check and get back to you on that tomorrow.
