Thank you for the information! Good to hear that.

Depending on what your custom board files were based on, there may have been more setup in the DK's files compared to your custom board.

Best regards,

Michal

Hello,

I found the solution.

I’m not sure why, but uart0 must be configured in the .dtsi file. After adding the following configuration, everything started working correctly:

&uart0 {
    status = "okay";
    current-speed = <115200>;
    pinctrl-0 = <&uart0_default>;
    pinctrl-1 = <&uart0_sleep>;
    pinctrl-names = "default", "sleep";
};

With that, it worked. Thank you!

Hello,

Just a quick check: does the same happens while using Segger J-Link Mini EDU and the on-board debugger?

Are you able to test that?

Best regards,

Michal
