Hello everybody.

I am using my own board with an ESP32E_WROOM with the initial configuration for the strapping pins corresponding to the datasheet (PD or PU). I am using a micro USB to power up my ESP and sending code. Everything worked very good but recently I tried something on the board because I made a mistake on the schematic. The wire (connected to GND) has been left floating and might touch the RX or TX pins from the USB UART driver that i am using FT231XS. Since now, i have this kind of logs when I try running my ESP32 :

Done
I have a LED that is always powered up when I plug my USB. I also have the correct strapping pin config on my board. When I use a ESP32 kit, the soft is running perfectly. I don't really know what to do now because it seems that the code is in the esp32 flash, but the ESP cannot communicate with the flash. Is it in deep sleep?

PS, I measured the current and the voltage coming from the USB port and I got 20mA on the VCC pin with +3V3, can it be the reason?

Do you have encryption enabled ?
If so it might be because your bootloader or your app has been loaded unencrypted. In this case you could try :
idf.py encrypted-bootloader-flash encrypted-flash

Hello Tanguy,

I worked on a nvs project with the encryption enabled. I tried you command line on a random project (blinky led) with no specific configuration activated in the menuconfig. Here are the logs :

I clearly don't have any sort of encryption activated in this project but I still have the same log as before when i run the idf.py -p COM flash monitor command.

It's seems the issue is somewhere else.

Could it be something about the flash not communicating with the µC? Because I can run the prog on an ESP32 devkit..

If the microcontroller could'nt communicate with the flash, you wouldn't be able to flash anything and you wouldn't get anything in the monitor.

Are you sure this board has never been encrypted ? Could you please run

Code: Select all

espefuse.py -p COMx summary
and share the setting of eFuses ?

Hello Tanguy,

I didn't mentionned that I previously worked on a nvs project with encryption data inside the nvs partition. In fact you're right, the board has been encrypted.

I am actually reading this document from Espressif : https://docs.espressif.com/projects/esp ... encryption

I didn't know very well about encryption but I think the issue here is the

Code: Select all

FLASH_CRYPT_CNT
bit set to 1 and not to 0.

I have checked the Security feature to see if I disabled the "Enable flash encryption on boot", then entered the

Code: Select all

 idf.py flash
and at last,

Code: Select all

idf.py efuse-burn FLASH_CRYPT_CNT
but it doesn't work very well, I got this error :

Code: Select all

Executing action: efuse-burn
ninja: error: unknown target 'efuse-burn'
command "efuse-burn" is not known to idf.py and is not a Ninja target
I am still working on this one, I'll let you know if I find the problem to this.

So your problem is that your board has encryption enabled and you are loading unencrypted bootloader and app.

You can try disabling encryption by burning FLASH_CRYPT_CNT to the value 3 (it will have two bits sets -> even number-> encryption disabled).

try :

Code: Select all

espefuse.py -p COMx burn_efuse FLASH_CRYPT_CNT 3
then reflash module.

Thank Tanguy, that was the issue. I will continue to read the Espressif documentation to avoid other issues with encryption.

Just by curiosity, could I have flashed an encrypted bootloader instead of disable encryption? I think this is the first thing we have tried but it didn't worked... Do you have any idea?

Why the FLASH_CRYPT_CNT need an even number to disable the encryption?

Just by curiosity, could I have flashed an encrypted bootloader instead of disable encryption?
Yes. It failed because you tried with another project that had the development mode disabled.
After enabling encryption in menuconfig, you first use

Code: Select all

idf.py flash bootloader-flash
It will generate encryption key and burn it in efuse before flashing.
If release mode is selected in menuconfig, it will also burn DISABLE_DL_ENCRYPT eFuse and the firmware can not be reflashed (ever).
If instead developement mode is selected, you can alway reflash the firmware with

Code: Select all

idf.py encrypted-flash monitor
To anwser your question, if your project had encryption enabled with development mode AND your board was already encrypted with DISABLE_DL_ENCRYPT at 0 then it should have worked.


Why the FLASH_CRYPT_CNT need an even number to disable the encryption?
Note : an eFuse is an hardware bit that can only be set, never cleared. You can not set an eFuse to 0 if is 1.

The eFuse summary tip for FLASH_CRYPT_CNT is : Flash encryption is enabled if this field has an odd number of bits set.
Odd number of bit, not odd value. 0b0011101 (29 in decimal) means encryption is disabled.

To understand how it works :
If you flash you board again with a encrypted-enabled project it will automatically burn another fuse and it will set its value to 0b0000111.
If you want to flash an unencrypted project again, you can burn another fuse and set it to 0b0001111 value.
You can do that until you get 0b1111111 value then encryption will be permanently enabled because there is no way to set another eFuse.

Hello Tanguy sorry for the late answer.

I understand now thank you so much for your help. I'll be more careful next time i work with encryption. :D

Wish you the best!
