Can you just use a LED to check which line of code it's getting to ? (move one line of code at a time) You can also run the bootloader in debug mode and add some break points ?

Unfortunately, I can't. Everything stops working after the program enters nrf_bootloader_app_start(). I have a blinking LED and it stops blinking. The logs stop a bit before entering that function, but I guess that's because something went very wrong and it didn't have the chance to print the missing logs.

Hi Andy,

Could you print out some log from inside nrf_bootloader_app_start() to check where there program stucks? nrf_dfu_mbr_init_sd() is the call to initialize the softdevice from the bootloader. I don't think you should have any problem calling it.
