My question is about whether VM has the option to load the files from the "Data" folder inside arduino sketch for the ESP32 board, and that it has the data partition in FAT (FATFS) format.

Same question for ESP8266 and LittleFS partition

Similar to the option that can be seen in the attached images.

Thanks for your answer.
As I understand it, Esspresif has adopted FATFS by default in its ESP-IDF (Espressif IoT Development Framework), and the latest adaptation for Arduino already includes the latest version of ESP-IDF 4.4.
It looks like the future for Arduino will be with FATFS.

Regards

Hi Simon, Thanks for the update.
I have been doing different tests of uploading the "Data" folder of my ESP32 in FATFS format but I have not succeeded.
This is the message log I get:

My configuration options are those that are in the images that I attach:
The programs "mkfatfs.exe" and "mklittlefs.exe" are also available in the folder: C: \ Program Files \ Utilidades64Bits \ MVStudio \ 2022 \ Common7 \ IDE \ Extensions \ 2wwezjof.0ni \ Micro Platforms \ espressif \ tools

Even though I change from one option to another, the spiffs version (ESP32_Base_V01.ino.spiffs.bin) is always generated instead of the FATFS version (ESP32_Base_V01.fatfs.bin) as it happens inside the Arduino IDE.
I have also tried to generate the local board.txt file but I have not obtained any difference.
Please, can you indicate any option that I may be forgetting?
Thanks in advance

Hello,
These days I have carried out different tests with several options:
- Clean Solution
- Rebuild Solution
- Build Solution

But I have not managed to generate the file ESP32_Base_V01.fatfs.bin in any of them, the file ESP32_Base_V01.ino.spiffs.bin is always generated and sent.

This is the log with the "Verbose" option, Is there something relevant to see the origin of the problem?:

Simon,
It does not seem that the problem is only the file name change, since my ESP32 program uses FATFS and cannot recognize the partition, and it does not find the three files that are loaded ("config.json", "registries.json" , "sensor.json").

On the other hand, if I generate the data partition within the Ardion IDE and upload it to ESP32, when my program restarts, it can already read the three files.

I have also seen that the version of "mkfatfs.exe" used by VM is the same as the one used by Arduino IDE and it is version 0.3.6.

I am very interested in solving this problem, can you indicate any additional action that I can do?
Thanks

The issue should be resolved in the latest release (21.11.08.0), available from the top of the below board:
