STM32L476RCT6, use CUBEMX generate the project, use FREERTOS ,SDIO 4bits, DMA, and Fatfs, the SD not work normally, the library is STM32Cube_FW_L4_V1.18.0, the question repetition on other library
in fuction
DRESULT SD_read(BYTE lun, BYTE *buff, DWORD sector, UINT count),
event = osMessageGet(SDQueueID, SD_TIMEOUT);

can not receive message.

but use sdio 1bits，work normally.

I fixed it, must enable SD dma irq in main function, then init the SD IRQ in HAL_SD_MspInit function.
