Are you using the latest version of nRF Connect SDK? If not, can you test with the latest v2.0.1 release to see if you are still able to reproduce this issue?

Hi,

Can you share your devicetree overlay file? Which pins are you using for the UART?

Have you tested other pins, to see if the pins you have selected could be assigned to other peripherals, etc?

Best regards,
Jørgen
