I bricked my module...

I tried secure boot and signing, but something goes wrong and doesn't work. Now, disabled all security features in menuconfig and incremeted FLASH_CRYPT_CNT.

Is it possible to fix it?

Still no luck. Please look at exactly steps:
1. I have generated "maxbt_key.bin" for encryption and "secure_boot_signing_key.pem" for signing. It's in "secure" folder in project.
2. Cleaning project

Code: Select all

F:\GitHub\ble_spp_server>idf.py fullclean
Executing action: fullclean
Done

2. I made bootloader

Code: Select all

F:\GitHub\ble_spp_server>idf.py bootloader
Executing action: bootloader

==============================================================================
Bootloader built and secure digest generated.
Secure boot enabled, so bootloader not flashed automatically.
Burn secure boot key to efuse using:
        C:/Users/jacek/.espressif/python_env/idf4.4_py3.7_env/Scripts/python.exe F:/GitHub/esp-idf/components/esptool_py/esptool/espefuse.py burn_key secure_boot_v1 F:/GitHub/ble_spp_server/build/bootloader/secure-bootloader-key-256.bin
First time flash command is:
        C:/Users/jacek/.espressif/python_env/idf4.4_py3.7_env/Scripts/python.exe  F:/GitHub/esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 --port=(PORT) --baud=(BAUD) --before=default_reset --after=no_reset write_flash --flash_mode dio --flash_freq 40m --flash_size 4MB 0x1000 F:/GitHub/ble_spp_server/build/bootloader/bootloader.bin
==============================================================================
To reflash the bootloader after initial flash:
        C:/Users/jacek/.espressif/python_env/idf4.4_py3.7_env/Scripts/python.exe  F:/GitHub/esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 --port=(PORT) --baud=(BAUD) --before=default_reset --after=no_reset write_flash --flash_mode dio --flash_freq 40m --flash_size 4MB 0x0 F:/GitHub/ble_spp_server/build/bootloader/bootloader-reflash-digest.bin
==============================================================================
* After first boot, only re-flashes of this kind (with same key) will be accepted.
* Not recommended to re-use the same secure boot keyfile on multiple production devices.

and

Code: Select all

but i think that i didn't do this:

Burn keys to blocks:
 - BLOCK2 -> [there is secure-bootloader-key-256 from file]
        Reversing the byte order

A fatal error occurred:         BLOCK2 is read-protected. The written value can not be read, the efuse/block looks as all 0.
        Burn in this case may damage an already written value.(use '--force-write-always' option to ignore it)

so i'm not sure if it is safety to do this burning.

Please give me some advices.
On monday i will have new esp module. I don't want to brick it also.

3 means encryption is disabled so flashing encrypted binaries won't work.

Thank You WiFive for response.
Indeed, I manually incremented FLASH_CRYPT_CNT when tried to disable encryption. So, should i use this one more time?:

Code: Select all

espefuse.py burn_efuse FLASH_CRYPT_CNT

I found that it can be used for disabling flash encryption, but since it increment FLASH_CRYPT_CNT, it can be used also for enabling? I have enabled Enable flash encryption on boot in menuconfig but it appear that it not touch FLASH_CRYPT_CNT.

Secure boot key was already burned to efuse so if you don't have a copy of this original key then you are stuck

I replaced module for new one and started again from the beginning. I want sign and encrypt app.
I want share encryptet firmware for customers, that they can self updating device.

1. settings in menuconfig:

- Enable hardware Secure Boot in bootloader
- Secure Boot Version 1
- Secure bootloader mode (Reflashable)
- Enable Sign binaries during build
- Secure boot private sisigning key: secure/my_secure_boot_signing_key.pem
- Enable flash encryption on boot
- Enable usage mode: Development
- enabled Check flash Encryption enabled on app startup

but why? i turned it in menuconfig. What is the problem? Should I use 'One-time flash' not 'Reflashable' Secure bootloader mode in menuconfig?
In point 12, there is:

Code: Select all

Warning: Image file at 0x1000 doesn't look like an image file, so not changing any flash settings.

So I think this is the reason that eFUSEs are not set. But what this warning means?

The first flash you don't encrypt anything and it will encrypt itself when it boots. Or you have to manually enable the efuses if you want to flash encrypted binaries.

I would suggest to test with secure V2 in dev mode, which will save you few devices probably.
In dev mode you may test it without burning any efuses and eventually have efuse partition to emulate it.

Thank You WiFive for information. I didn't know it.

I burned manually:

espefuse.py burn_efuse ABS_DONE_0
espefuse.py burn_efuse FLASH_CRYPT_CONFIG 0xf
espefuse.py burn_efuse FLASH_CRYPT_CNT

all ended successful

Should I flash everything one more time after burning eFUSES? Because earlier after first boot it was double encryptet (I flashed ancrypted files and module encrypted one more time on first boot)? Or what else is wrong?

I have enabled "Enable flash encryption on boot". Is it correct when I'm flashing encryptet files or should i disable it?

I would suggest to test with secure V2 in dev mode, which will save you few devices probably.

Thank You chegewara but i have S0 version (without V2). At least for now.

UPDATE:
I disabled "Enable flash encryption on boot" and reflashed bootloader-digest and app and now program starts.
Thank You for help.
