lbh00 how what can I do to debug this ?
Have you tried my earlier suggestion with modifying a print statement at the beginning? That way when you load with
newtmgr you can immediately see, even after a reset, that you’re running the correct firmware.
I have a feeling that it is MCUboot related. would the mcuboot from nordic work if I flash it onto the feather ?
It’s the same exact boot loader so I’m not sure how it will help you here.
Remember when your app loads, it will download whatever file you have targeted in the cloud. If that
app_update.bin is outdated it will show the previous/outdated functionality. Without seeing what you’re having trouble with here it’s hard to debug.
