External NRF52832 Program with NRF52DK - Reset not working

[Nick]

Hi,

I'm trying to program an external NRF52832 board with the NRF52-DK, per the instructions in this post.

Programming works fine, but the code doesn't execute after reset. I'm using nrfjprog (on OSX) with --chiperase --program and --reset. The code doesn't run until I manually power-cycle the external board. Then, interestingly, if I issue another command with only --reset, the code stops until I power-cycle again.

Any thoughts on what might be causing this?

Thanks!

EDIT:

Using nrfjprog version: 9.4.0, JLinkARM.dll version: 5.10d

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?
