RE: Need to verify my FT2232H minimodule can be used for flashing and showing debug message via UART.

Hi,

Disclaimer: we support segger based debuggers. I'll try to help to debug the connection itself, but any software related issues must be brought up with the openocd community.

The nRF52833-DK must be on when in NRF ONLY mode, and you need to power it through USB, like you do.

Try measuring the voltage on the "VDD" of your kit, that should read approx. 3.0V.

Assuming it is a one-to-one connection in your interconnect board, you have connected GND, RESET, SWDIO, and SWDCLK.

It is very important that your external debugger is 3.0V compliant.

Do you have another debugger to test your connection with (for instance, if you have two kits)? If yes, I would recommend trying this first to see if you're successful in connecting to the external board.

Kind regards,

Håkon
