How to make SDIO & eMMC FatFs Work with STM32F4 ?

[Mcherif]

Hello

I am using :

• STM32F413HDESCOVRY
• STM32 CubeMX tool
• Atollic TrueStudio V9.3
• eMMC : Kingston EMMC04G

I already created the files

• user_discio.c
• user_discio.h
• eMMC_Driver.c
• eMMC_Driver.h

when i use f_mount i get FR_NO_FILESYSTEM

thx

Blank eMMC devices will need to be formatted. If you've validated the READ, and then WRITE functionality, you're ready to use f_mkfs()

I found these ODROID cards to be less of a circus

STM32F413H-DISCO eMMC test code, blind port, I don't own this board.

Outputs via VCP at 115200 8N1, at first prompt hit ENTER, will prompt to format if necessary.

Thank you for your reply. I tried your source code it happens to connect with the eMMC but it can neither write nor erase. I tested it with several eMMCs always the same thing in the attached file you find all msg.
