hello

i am using the SDIO interface of an STM32F205vft6 to access an sdcard.

for this purpose i am using the MSC class (USB interface) and STM32cubeMX v4.13.0

when i plug the usb the device is recognized but i have a message that says that the

sdcard must be formatted ( i tested the sdcard with a reader and it is already formatted in FAT32).

thanks.

So this is symptomatic that the SDIO read function isn't pulling the right data from the right blocks.
