Hi there
During updating nRF5340 over bluetooth, really rarely the CPUNet fails to be updated over bluetooth.
The mcuboot says: Image in the secondary slot is not valid!
But with the exact same Smartphone, bootloader on nRF5340 and dfu_application.zip, the update also works later.
What could be the reason for this and how can I debug it?
Our customer is saying that the update always fails with Google Pixel Android Version 13 nrfconnect Version 4.28.0.
I tried a Galaxy S21 (Android 12) with nRF Connect App 4.28.1, but here it is working several times.
What is even worse, is that the CPUAPP is still updated and then the bluetooth communication fails and no new update can be tried.
How can I prevent the mcuboot bootloader to update the CPUAPP when the validation of the image 1 fails?
