Hi ,

I'm looking for an example with SDIO+eMMC (and not SD). Is there something like that ?

Another thing: Someone has information on eMMC commands ?

Thanks

Mikael

I've got eMMC working with the STM32 in 8 bit mode with single data rate. The STM32 SDIO peripheral doesn't support dual-edge clocking so there's no dual data rate. I don't have any of the secure features and I don't use streaming, just init, read/write single block and read/write multiple blocks. 

What information are you looking for in particular? I probably can't share all my code but I'd be glad to point you in the right direction.

Hello,

I am working with a STM32f205 and a THGBM4G4D1 eMMC. I use the SDIO + DMA.

 I started from the example code from ST and used the JEDEC standard. 

I have the initialisation and erase functions working but I can't get Read and Write (single and multiple block) working. Can you please send me your low level functions at 

pmc696 _at_ hotmail _dot_ com ? 

Thanks,

Alex

Hello Andrew,

I sorry to bother you, but if could share your code or pointers about interfacing the STM32F2 and eMMC with me it would be a great help.

I have used the STM32F2xx to access SD cards via SDIO and SPI, so I think I just need to know the differences between SDIO and eMMC access.

My email: vneff at partechgss dot com

Thanks again if you can provide me some guidance!

Vance
