I am working on a device based on the beloved ESP32 chip and almost completed the main firmware for the different functionalities, including BLE communication with a smartphone app, relay control, cryptography and even more. I am totally impressed by this chip! The only issue I have (maybe personal lack of experience and knowledge) is the use of the two really important safety features:
- secure boot
- flash encryption
So, to sum up, do you have any material / tutorial / example to suggest for Secure Boot and Flash Encryption?
Or maybe, if anyone is willing to write down a basic step to step process with a few code examples?
Thank in advance for any kind of help and have a nice day!
