The STM32U575 MCU can not use a 4 Bit SD card in 4 bit mode. Using the driver and FAT32 from qubeMX result in an error. The error is that the bits are shifted by 4 bits. What do i do wrong or is this a known issue. If it is an issue, is there a quick fix

did you even get anywhere on this?

I'm seeing the same issue on the 'U5A5.

works perfectly in 1-bit mode. but 4-bit mode fails (even with the clock at 400kHz)

nothing mentioned in the errata.
