SecureBoot + FlashEncryption + OTA !
Posted: Sat Feb 06, 2021 12:12 pm
Hi,
I enabled the Secure boot and Flash encryption and trying to perform OTA.
But I dont Know how to perform OTA After enabling Security features (Secure boot and Flash encryption ),
I Successfully done the OTA without enabling the Security features (Secure boot and Flash encryption ).
1. how to perform OTA After Enabling Security Features?
2. Did I need to Encrypt the OTA image before Performing OTA?
3. Do I need to encrypt the OTA image internally with my firmware? If yes, How to Encrypt the OTA image internally after Receving the Image in the firmware?
I performed OTA after Enabling the Security feature without Encrypting the OTA Image (app.bin file), I got the following Output...
Thank you,
Regards,
