I am using STM32L4x6 MCU in our custom board. I developed the firmware with FatFs to add support of SD card using SDMMC1 interface. I am successfully able to interface the 2GB micro SD card and able to write files onto it.

But when I tried with 8GB (Micro SDHC) SD card in the same setup and with same firmware, it didn't work!! I tried SD card of different manufacturers like SanDisk, Transcend and Samsung, but none of them worked.

Do I need to modify the firmware to add support of 8GB card?
Please help.
