Change UART pins dynamically

[Avgerinos89]

Hello

Is is possible to change the UART pins dynamically?
I am thinking to predefine the pins on device tree as follows:

&uart1 {

    status = "okay";

    current-speed = <115200>;

    pinctrl-0 = <&uart1_default>;

    pinctrl-1 = <&uart1_sleep>;

    pinctrl-3 = <&uart1_3_default>;

    pinctrl-4 = <&uart1_4_sleep>;

 

};

and then choose between different pinctrl on runtime.

Is this something possible? Is there any other way to achieve that functionality?

Thank you

Hi

Currently there is no official way of doing it Zephyr. There a PR in progress that I would suspect might be ready for the next release for NCS(3.1) which is due to come out later this year. 

A colleague of mine made a workaround for this  which can find here I would note the sample was made for NCS 2.5.x so it might not work out of the box for a newer version of NCS
