It's okay. I already know the reason for this problem.

This is because the erasure operation does not go through the encryption engine. At this point, the data inside is 0xFF.

Then, when using the read operation, the QSPI will automatically decrypt it, resulting in the value read out not being 0xFF anymore.

Therefore, after the magic check, it is determined that the magic has been set. After decoding, detected incorrect in the values , so it is considered that it is an invalid and badimage.

Hi,

I am checking this internally and will get back to you. Please expect a slight delay due to the summer holidays here in Norway.

Regards,

Priyanka
