Question
STM32L5 SDMMC write/read fails because of timeout
I configured as follow the SDMMC bloc and completed the functions SD_read and SD_write using SDMMC + DMA.
The problem is that HAL_SD_ReadBlocks_DMA returns Error before even starting the transfer with the errorcode 0x00000008. I really tried everything but i still get that error.
I am using the wide bus 4 bits for SDMMC and the clock is 40MHz, SDMMC interrupt is enabled and all the pins are pulled up.
Can you give me some solutions ?
