Hi All

I want write on the SDMMC using HAL_SD_WriteBlocks_DMA system call. The function itself works, the sector on the SD is written, but no callback function (HAL_SD_TxCpltCallback) is called.

Did someone experienced such trouble ?

Thanks

in CubeMX also the SDMMC1 global interrupt shall be enabled in addition to DMA interrupts.

 

Thanks to all

Make sure you have all the IRQ Handlers set up and that they call into the HAL layer

    Hi

    the RX callback is working, only the TX isn't. I registered the callback in both manners: by the _weak pragma and using the HAL_SD_RegisterCallback, but still only the RX callback works.
