Secure mcuboot reliability issues

Hi,

I’ve got mcuboot (the Arduino variant) up and running. I’ve got my keys configured and everything was running great. However, after a few hours of the normal dev cycle of download, RST, download, CTRL-C halfway through etc etc it’s now in a state where it won’t transition to the pulsing purple swap state, instead it sits with with a non pulsing green. Reflashing the bootloader, reflashing keys and formatting and reflashin the QSPI make no difference.

Anyone else seen this type of instability or indeed know how to unstick this sort of state?

Note: this is mcuboot secure stuff not Arduino OTA

Thanks

I will plug a debugger in tomorrow but just looking for any mcuboot experienced “oh yeah, you probably did blah and it’s fixed like this”. :slight_smile:
