SD card example throws errors randomly

[eduard-firewave]

Hi, I'm running the SD Card example and I get the errors on each run. The errors seem to appear in random places - not consistently. Here is the sample output:

Replace the SD card and test it. The SD card has no other components and is directly connected to the ESP.

It stopped recognizing the card now. Tried several SD cards (all work on the PC and are FAT32 formated). Actually tried several T-SIM7080 boards as well. And the same SD card is working on T-SIM7670G board.

A7670 uses SPI driver, while SIM7080 uses SDMMC 1bit mode. It seems that the problem has been fixed in versions greater than 3.0. You can test it.

I am using the platformio with vscode. I upated the env to
[env:t-camera-sim7080]
platform = espressif32 @ 6.9.0
framework = arduino
board = esp32s3box

and it solved the issue.
Thanks so much for your support!
