Hi, we've a custom board with an nRF52820 chip on, and are just at the start of bringing the board up.
Previously we've been developing our code on the nRF52822DK, and doing ok.
We had a blinky program, and I'd managed to flash that onto the custom board, and was starting to probe if it was actually running, but now I can't connect to the target board.
We're using a Jlink base to program and debug, and the SWD interface (with the reset line connected), and the target's getting a good 3.0V supply to the target.
We've been using VS code and have tried resetting and erasing the board, but get an error like:
-- west flash: using runner nrfjprog
-- runners.nrfjprog: Flashing file: /Users/nRFprojects/220905//build_P/zephyr/zephyr.hex

NOTE: For additional output, try running again with logging enabled (--log).

FATAL ERROR: command exited with status 33: nrfjprog --program /Users/nRFprojects/220905/build_P/zephyr/zephyr.hex --sectoranduicrerase --verify -f NRF52 --snr 51028748
As suggested, I've tried running that with the --log option but it says:
FATAL ERROR: runner nrfjprog received unknown arguments: ['--log']
I'm updating to the 2.5 toolchain now, but don't expect that'll help, so any help or advice on how to unbrick the board would be very much appreciated!
