ESP32 - supported types of microsd cards

[sazanof]

Hello. In my project, I use storing the web interface on a memory card. I couldn't get ESP 32 to recognize the card for a very long time. I've tried a lot of options.

regular microsd 1gb - error (type not supported)
16GB microsdhc memory card - CRC verification error
4gb MICROSDHC U-1 memory card - everything is fine
64gb Samsung evo microsd U-1 - everything is fine

(pullup-s enabled)

See file below

I don't need to use memory cards > 4gb

Q: What types of cards are supported in ESP32? I have not found clear information in order to definitely know what to buy. I would not like to play the lottery. Tell me, please .

Hi sazanof,

There is no list of supported types of micro SD cards available.

To help you with the reliability of the SD card use could you share the particular type of ESP32 device (module) you are using and code fragment showing, how is the SD/MMC driver initialised, respective where does the error codes you have mentioned come from ?

Could you also clarify whether you have software enabled pull-ups on the respective GPIOs in ESP32, or physically attached (soldered) pull-up resistors ?
