I'm testing F767Zi-Nucleo to write some data to a 16G SD card with no file system.
With HAL_SD_WriteBlocks function, everything works fine.
I can read out the data that just have been wrote.
With HAL_SD_WriteBlocks_DMA function, no error during excution.
But I can only read out 0x00 in the data block that just been wrote before.
SDMMC controller clock frequency is 4 MHz.
SDMMC1 and SDMMC2 are tested and they both have this problem.
Has anyone encountered same situation? Need help.
Thanks a lot.
