Hello everyone!
After I enabled the Release Mode of the Flash Encryption in the ESP32-S3 I get this error:

E (529) flash_encrypt: Flash encryption settings error: app is configured for RELEASE but efuses are set for DEVELOPMENT
E (530) flash_encrypt: Mismatch found in security options in bootloader menuconfig and efuse settings. Device is not secure.

I know that using ESP32 the eFuse DISABLE_DL_ENCRYPT needs to be manually burned in order to remove this message, has anyone encountered (and solved) this on the ESP32-S3 as well?

Thank you very much!

For the ESP32-S3, similar to the ESP32, one common eFuse setting that affects flash encryption is DISABLE_DL_ENCRYPT. If you're encountering this error after enabling flash encryption in RELEASE mode, it's likely that you need to burn the DISABLE_DL_ENCRYPT eFuse to disable flash encryption.
