Arduino framework issue with 4 bit mode

[holefrog]

Hi,

Thank you for your component. I am trying to use it with my ESP32-CAM board.

I formatted the 8G micro-SD card using Fat32. I can get the picture of the camera, however the values of 'SD card used space', 'SD card free space', and 'SD card type' are 'unknown'. I am not sure what the issue is, might be a defective board or not.

Below is my yaml:

The logs show that "Component sd_mmc_card is marked FAILED"

Hi,

Thanks for your interest in this project.
After testing their is an issue with the component in 4 lane mode, I will look into it.
In the meantime, you can try the 1 bit mode wish seems to work as intended.

After some investigation it seems the issue come from the latest arduino framework version (>3.0.0), using the version 2.0.17 solve the issue.

esp32:
  board: esp32dev
  framework:
    type: arduino
    version: 2.0.17

I will try to see what need to be done to migrate to the latest version of the arduino framework

Hi,
Thank you for your quick response.
It works after changing frame work to 2.0.17 manually. Now, I can get SD card information. I am going to try other functions.

Merry Holidays,

I have passed more time on the issue and I was totally mistaken with my interpretation.

The problem does not come from the 3.0.0 version of the arduino framework, from my understanding it is not possible to use it with esphome.

At the moment the arduino framework version used by esphome are:

• recommended: 2.0.5
• latest: 2.0.9

From that point I have found the pull request resolving the issue espressif/arduino-esp32/#7646 in the version 2.0.7

I will update the documentation to reflect this findings
