Have you managed to implement secure boot with flash download tool ?

Hi all, I am currently trying to automate the process of implementing (Reflashable) Secure Bootloader v1 and Flash Encryption. The security features are to be implemented on several ESP32s with the same secure boot key and flash encryption key. (I know this isn't ideal but it will suffice for now). ...

Have a look in the menuconfig and check in the Security section if the Secure Bootloader settings are properly ticked.
