Dear All

We are facing some issues on eMMC integration with STM32F765 micro controller , In STM32CUBE we generated SDIO interface source code , eMMC manufacture is says this source code was SDcard interface. How we can generate emmc source code fromSTM32CUBE , or we can get any library on EMMC ? Pls suggest me how to resolve this issues.

Hello Clive,

Can you post some source code ? an example of using an emmc with HAL.

Thanks !

Code is currently only being shared with project contributors and sponsors.

I'm looking for some 64GB and 128GB ODROID cards, custom boards with eMMC would also be of interest.

Matteo,

I'll attach a .HEX file for my current demo for the STM32L496G-DISCO, it outputs to the VCP at 115200 8N1, use the ST-LINK Utilities to update the firmware, and then a terminal application of choice to connect to the COM port created by the board's ST-LINK.

This will dump some sectors, read a directory, write and read some test files. Tests access layer with multiple block sizes to ensure data coherency.

I'm using Keil, and using the HAL CubeL4 example trees as a basis for placing the project

E:\CT\STM32Cube\Repository\STM32Cube_FW_L4_V1.0\Projects\32L496GDISCOVERY\Applications\FatFs\MMC-001

ST has just release the V1.0 version, I'll probably port over to that.

I have localized versions of these files addressing the MMC specific patches and debugging output, and have a USE_EMMC define to selectively build for SD or MMC use cases.
