Hi, I have a custom board with an nrf52840 onboard I was able to program the nrf52, but then I executed:
% nrfjprog --eraseall
and,
% nrfjprog --pinreset
and the JLink can no longer communicate with the board. I get a "No idcode detected" on SES. I have also tried nrfjprog --recover and it was not successful. I thought it may be a bad board, but I now have two boards in the same state.
% nrfjprog --family NRF52 --recover
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
All tools are the latest.
log.log:
Voltage looks good. Let me know if there is anything else that can help debug.
