I am working on custom PCB and have BMD-300 Module (nrf52832). When I am running the code on NRF52832 Eval Kit the serial monitor is working fine but when I am using custom board it do not print any data and some garbage data after some time. Other operations are working fine. I am using SEGGER Jlink v9 (SWIO).
I have also followed another tutorial for RTT with simple Hello World example but it is also not working:
Setting up console over SWD interface
