External NRF52832 Program with NRF52DK - Reset not working

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
