Flashing Bootloader to NINA-B306 always fails

Official Hardware Nano Family Nano 33 BLE
1

Hello,

I've build my own board using the NINA-B306-00B module and am attempting to connect a CMSIS-DAP programmer to an existing Nano 33 BLE board to make sure I can successfully to flash a bootloader before doing so on my own boards.

I'm currently using the DAPCAT v1.2 from electronic cats, in combination with the pogo pin adapter from sparkfun. I have my board on a vice so that I can consistently place the pogo pins on the board, and haven't had any issues with that.

I've checked all my connections, SWD/SWC/3.3V/GND/RST are all correct.
When attempting to burn the bootloader, I get the error message:

CMD_INFO Failed: sent 0x0 and received 0x3.

I'm away from my workbench and can paste in the full output in a little bit.

I haven't had much experience with CMSIS-DAP, so I'm wondering if there is a step that I am missing before I can use the debugger. Any feedback would be wonderful.

Thanks!
