From your failed log, it seems your board could not boot up and be recognized by your host.
If your module could work on the devkit as expected, please check with your hardware team about why there’s no serial console output.
It should work and enabled by default on UART2 (uartc@c280000) if you have similar design as the devkit.

Please also note that your custom board should not work with SDKM because you have the custom board design with respect to the devkit.
