Hi.
I haven’t found any information about that error :/
Does that happen only with that specific project or with all projects that you try to upload the data?

Hi Sara, Thanks for your answer.
It Happens using platformio with all projects when i build Filesystem Image before to upload it in the ESP32.
Now, I have added  the 99-platformio-udev.rules at the right place and have got a mkspiffs file but i don’t know where to store it.
Some issue ?
Thanks a lot,

Hi again.
Taking a look at the error, it seems that it should be on this directory:  .pio/build/esp32doit-devkit-v1/
However, I don’t know why you need to do this procedure, because it should work without having to do that.

Hello,
I crossed the same problem today and after half a day I found the solution here:
https://github.com/philbowles/ESPAsyncWebServer/issues/3
It seems there is a missing update in a file. There was a “solution” to use the 4.5.0 version (today is 5.1.1) of the espressif32 plateform by forcing its use with adding

platform = espressif32@4.5.0

in the plateformio.ini file, this is the first that works. BUT then it blocs at the filesystem image building.
So, the above solution ask to change 3 lines in the file

<your project>/.pio/libdeps…/ESP Async…/src/WebAuthentification.cpp

Change these 3 lines :

mbedtls_md5_starts(&_ctx);
mbedtls_md5_update(&_ctx, data, len);
mbedtls_md5_finish(&_ctx, _buf);

by:

mbedtls_md5_starts_ret(&_ctx);
mbedtls_md5_update_ret(&_ctx, data, len);
mbedtls_md5_finish_ret(&_ctx, _buf);

Then save it (Ctrl+s).
As long as they do not correct the bug, this will burn other neurones…

Kind regards,
Mathias
