ESP32 secure boot still not supported?

[jeremiahlandi]

Hello all!

I want to confirm that neither secure boot or flash encryption is supported. I have done a fair bit amount of research and have only read that it isn’t.

My goal (at this time) is to prevent someone from downloading the firmware off of the processor.

I understand that it has been defeated but I would say people still use locks even with the “lock picking lawyer” in existence.

The “Secure Boot” and “Flash Encryption” of the current ESP32 has been defeated in November last year. Only new silicon-revision chips (starting at ESP32-D0WD-V3) fix the problem."

Research:

Is it possible to integrate the ESP32 secure boot module with platformIO? For those unaware, this is what I’m referring to.

Hi This is possible to use Flash encryption and boot secure with platformio on esp32 chip?

Hello, I want to prevent my code against flash reading. I find in the manual of the esp32 the possibility “flash encryption”. Is that the right way to protect my code against read access? How can I enable this? I am using the arduine framework on PalttformIO. Is a manual or a code example available? Best regards Tom

Hi @jeremiahlandi, I also just ran into the same issue, does it have any updates?

Thank you!
