Hi,Basically we started to develop the X-CUBE-SBSFU package for NUCLEO-L476RG.Then, we generalized it.1) Why SE_CoreBin?On Nucleo-L476RG, the protected code runs in the Firewall enclave. We must respect the following constraints:All required code mus...
Another possibility to consider if you really want to optimize the FLASH usage: do you really need the backup feature?If this is not needed, then let's skip the backup and then you are on the safe side I guess.You download the encrypted image in EXTE...
At first sight, it seems that the swap algorithm does not deal with encrypt/decrypt.This is "expected" because in our examples the slots always belong to the same FLASH area (either both slots in internal FLASH or both slots in external FLASH). ...
Regarding your question about internal FLASH and encryption: I need to check what the code expects.But, from a design perspective, as soon as we are in internal FLASH, it is acceptable to work with a clear image.We impose the encryption for the exter...
I will double-check, but as far as I remember:the SBSFU code is not really "aware" that the external flahs is encrypted: it only activates the OTFDEC and all operations are handled "smoothly" by the OTFDEC.OTFDEC should not hinder the performancesI w...
