Thank you. Since lowering the clock to 40Mhz, it works fine.

Yes. Two mount.We found that when connecting two SDMMCs to FatFS, there is no initialization code in the SDMMC initialization functions (MX_SDMMC1_MMC_Init, MX_SDMMC2_SD_Init). /** * @brief SDMMC2 Initialization Function * @PAram None * @retval...
