How to Make the Console Sample Work on Custom Board with nRF52840_CKAA_R7 Package

Hello,

We are using the nRF52840_CKAA_R7 package of the nRF52840 on our custom board. The board's USB pin connections are designed based on the nRF9160-DK's nRF52840 reference.

I am trying to run the console sample from the nRF Connect SDK (NCS) on this custom board. However, the sample doesn't seem to work.

Here are the details:

  • The USB pin connections on our custom board match those of the nRF9160-DK's nRF52840 setup.
  • The sample builds and flashes without any issues.
  • There is no output over USB, and it seems like the USB connection isn't being recognized properly.

What changes should I make in the code or the configuration to ensure the sample works correctly on our custom board?

I suspect there might be some missing configurations for the custom board, such as:

  1. USB device tree bindings or pin configurations specific to the nRF52840.
  2. Custom board definitions or overlays required for proper hardware initialization.

If there's any additional information or log output you'd like me to provide, please let me know.

Thank you for your help!
