Actually I have managed to recover it by doing as described here: https://docs.espressif.com/projects/esp ... encryption
So now it is back to the drawing board to try enabling flash encryption again.

Ok.. now I am confused.. How did it got all the way to flash_encrypt: Flash encryption completed ? If bootloader encrypts the partition shouldn't it have failed before? In any case, is it possible to flash it again somehow or it is bricked now? This is the second device I have bricked by trying to f...

I have disabled secure boot and after flashing (and waiting) the following happened: I (29) boot: ESP-IDF v4.1-dirty 2nd stage bootloader I (29) boot: compile time 16:07:55 I (29) boot: chip revision: 1 I (32) boot_comm: chip revision: 1, min. bootloader chip revision: 0 I (39) boot.esp32: SPI Speed...

Hi, I have flashed it without refreshing and left it in bootloader for 5 minutes (is there no way to know encryption process status?). After connecting the monitor I got the following: rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_...

I am trying to follow the documentation and set up flash encryption on ESP32 (esp-idf v4.1) but it seems that I am missing something. With my current settings flash does not get encrypted on first boot. Do I have to burn eFuse manually and if so how? With espefuse.py burn_efuse? I have set up the fo...

The reason that I am asking is I would like to buy some ESP32-MeshKit-Light bulbs and upload my custom firmware to them but also I need them to be encrypted since they will contain some web login details. So bricking them during OTA is an acceptable risk for me. It is far better then breaking the bu...

Hi,

I am reading the docs regarding flash encryption and secure boot but can't seem to find if it can be enabled through OTA to previously unsecured system. So is this possible and if yes do I need to do something more than pushing OTA of the firmware with these settings enabled?

Thanks.

Hi,

Is it possible to copy efuse to hardware key registers so that it can be used as AES encryption key?
I would like to use it with hardware accelerated encryption to encrypt some generic data but without having to use flash encryption.

Yes platform.io doas support Arduino as a component, I'll use that approach then.

Thanks!

Hi,

The thing is I want to be able to use Arduino framework (using Platformio) for development but to still enable flash encryption somehow.
Would adding something like do any good here?
