Cannot program BM833 custom board for Bluetooth Direction Finding

Question

I have achieved bluetooth direction finding using nRF52833DK. I would like to do the same with a custom board. I have used the BM833 chip for doing this. I have attached the schematics of the board with this thread. I am flashing the device using Segger J-Link. The custom board is not detected in the VS Code nRF Connect SDK. Any idea what the issue could be? 
 I have followed this link to set up the custom board:

I had an issue with the SEGGER J-Link that I used. Once I changed it, the flashing worked.
