Won't detect SD card

[jwinfieldnz]

SD card is not detected

The ESP32CAM SD card doesn't seem to be detected too often. I have used a few cards from 8 to 32GB FAT and exFAT format but doesn't seem to detect the card at all. Maybe I have the SD card settings wrong, It does work on some occasions.

Arduino debug provides

E (84334) sdmmc_sd: sdmmc_check_scr: send_scr returned 0xffffffff
E (84334) vfs_fat_sdmmc: sdmmc_card_init failed (0xffffffff).
M21

Maybe a faulty card reader?

yes looks hardware/driver issue, can you share your configuration.h Did you do any change in FW? what version of esp32 core do you use in arduino?

Sorry. You can close this. I just tried a camera sketch and fails with that also.

try older core/ latest esp32 core git., there was some issue with sdmmc driver on some version

My esp32s3 has the same problem. Some cards can not be detected, and another 16g card is identified as 2G.

Can you recommend a suitable version

[luc-github]

normaly latest git should be ok as well as 2.0.4 as well as version currently used in esp3d V3 platformio

be sure also your card is formated using https://www.sdcard.org/downloads/formatter/

on my esp32cam the 16GB is well detected :
