Hello,
I have several custom 52832 bords that until recently worked fine with SDK15.
Yestrday I started experimenting with nrfConnect and flashed some Zephyr examples. It looks like an erroneous bin file used and now JLink cannot communicate with the board. For example, nrfjprog --deviceversion returns "ERROR: nrfjprog failed for an unknown reason. ..." when keeping nRESET low. If I let nRESET float, the messages changes to "ERROR: JLinkARM DLL reported an error. ..."
Note that no DC/DC inductors are installed to the custom boards, so I wonder if DC/DC mode was accidentaly enabled and now I cannot recover from that. However, if I completely remove VCC the error becomes "ERROR low voltage detected...", which implies the problem is not with the power.
The rest of the boards that were not flashed with Zephyr samples continue to communicate with JLink flawlessly, meaning that my JLink setup is fine.
Did I brick 52832? Below are the nrfjprog .log files.
