Hi all,
I've built a custom nRF9151 board, which is successfully responding to the basic factory AT commands. It won't accept a CFUN=1 command though, presumably because it's still loaded with the factory firmware.
I've only got access to a PicoProbe at the moment, which has worked great for flashing application programs over SWD, but I'm now trying to change the modem firmware to the production version and I can't find any way to do this without MCUBoot or a J-Link adapter.
Do I have any options other than buying a J-Link Edu Mini?
Thanks!
