nRF52840 DK UART logging not working

Hi All.

I am using the nRF52840 development board, and can't get UART logging to work. I have checked all the settings in sdk_config with no joy.

I have hyperterminal setup at 115200 bps, 8 data bits, parity None stop bits 1, and tried all combos of other hardware control, speed etc. It connects to the board virtual COM port ok.

The SDK example I am running is Central_Multilink. It works ok, just no UART logging.

Any suggestions would be appreciated. Attached is the sdk_config

sdk_config.h

Thanks
