Could you connected the EXT_RESET on the Debug Out header(p19) or the SH_RESET pin on P20 to the reset pin of the custom board(P0.21) and then try to reset the external board after programming it?

I'm using this arrangement exactly: devzone.nordicsemi.com/.../

No, I was just wondering if you're seeing the same behavior on other identical boards.How have you connected the boards together? Have you connected the EXT_RESET on the Debug Out header(p19) or the SH_RESET pin on P20 to the reset pin of the custom board(P0.21)?

I have multiple copies of this one which I've tried, but I don't have one of a different design. Is there one you could recommend to try for testing?

Hmm, do you have another custom board that you can test with?

Thanks. Even the 9.6.0 version linked from that page is actually 9.5.0 though.

Programming works fine other than this issue. I tried this morning with the updated software (nrfjprog 9.5.0 and JLink 6.16) with the same results.

My bad, this should be the correct link. Not other than lengths of the SWD lines on the custom PCB , but if that was the case then you should not have been able to program the external device.

OK, thanks, I just updated the software. The nrfjprog link and the link on the website labeled 9.6.0 seem to link to 9.5.0 though. I'm away from the hardware now but I'll let you know when I'm able to try again later today or in the morning at the latest.

Yes, the external board is a custom board, although it was designed by a third party. Is there anything you can think of that I should check for on the hardware side that could cause this?

The logs look fine, but could you try to update your nrfjprog to v9.6.0(link ) and JLink to v6.16 (link) and see if that solves the issue. Is the external nRF52832 board a custom board?

Thanks! Updated again.

There should be a log.log file in the folder where you called nrfjprog from.

Thanks for the reply. Added the requested info to the initial post above.

Which version of nrfjprog are you using? Could you also run the command with the --log option and post the log here?
