HAL_MMC_ReadBlocks CRC error in 8 bit mode SDMMC #26

Closed JudicaelK closed 1 year ago

JudicaelK commented 2 years ago

Hi,

I'm working on SDMMC on STM32U5 nucleo board.

Everything works fine for 1 and 4 bit mode.

But, in 8 bit mode I can write data with HAL_MMC_WriteBlocks but when I try to read back with HAL_MMC_ReadBlocks, it always gets SDMMC_FLAG_DCRCFAIL.

Have you ever met the same error? If yes, how did you solve it.

Thanks in advance

Hi @Judicaelkouadio,

You have mentioned in your comments that you are working on STM32U5 nucleo board. However, you have reported the issue on the STM32CubeH7 repository. Would you please clarify whether the issue is detected on the STM32U5Cube or SMT32H7Cube package ?

With regards,

Hi @ASELSTM,

I use STM32U5Cube. I didn't find the STM32CubeU5 repository on github. This is why I posted it here.

But the issue is for STM32U5.

Any idea?

Thanks.

Best regards.
