ESP-Jumpstart Examples with Flash Encryption, Secure Boot and OTA

[maveren]

IDF Version: v4.2-dev-1320-g1aebfdf6a
Hardware: DevkitC Wroom32u

Objective: Implement flash encryption, secure boot, and OTA with a forked version of ESP-Jumpstart: https://github.com/espressif/esp-jumpstart.

I have modified the ESP-Jumstart examples to use my own aws account and successfully tested OTA with remote app signing. Although, after I enable flash encryption and secure boot I get the following errors when the OTA update begins:

I have verified that flash encryption and secure boot (reflashable) are enabled correctly in DEV Mode.

Let me know if anyone has suggestions or if more information is needed.
Best regards
