Build the project, then flash to device, the rtt log:
Then we change CONFIG_MCUBOOT_IMAGE_VERSION="0.0.1+0", rebuild project, and use nRF Connect update the app_update.bin to device, everything is ok, but after device reboot, the rtt log is the same with old one:
The nRF Connect log:
The mcuboot exec the old firmware after upload app_update.bin success, how can this happen? What i missed?
