STM32CUBEMX ver 5.6.1 still not fix SDIO - DMA 4 bit mode issue ?

I'm using SDIO - DMA to read/write with uSD card.

In 1 bit mode, it work fine.

But in 4 bit mode, mcu cannot mount to sd card. It appears FR_DISK_ERR.

I've update to newest version of CubeMX but it still not fix.

Does anyone know how to fix this ?

Hello @Le Loc - Duc

Which chips? Which boards?

Do the demo's in the Applications directories work if ported to your hardware? Pull-ups on the command/data lines?

Easy enough to build broken hardware.
