Issue with printk() not printing to debug uart declared in overlay file

[MattHorton]

My debug uart stopped working after creating overlay files to make port changing easier. Is this a known issue? They're still the same pins and baud rates.

Hi Matt,

Please state which UART you have change and if you have set up the .overlay file correctly.

If you are using the nRF91DK and want to change the pins out to the external pins, you need to change the boardcontroller FW as well.

This is described in this thread.
