I have a question regarding the eMMC, I'm trying to interface with a Micron eMMC.

I have a Micron eMMC too, and I tried to use it by using the same code of the Sd/mmc example provided from LpcOpen, but it seems to doesn't work. (Initialization seems to be ok, but mkfs command not work). The same code work right with a SDHC.

Maybe I'm doing something wrong...

Is it wrong to think that the same code that work with an SDHC memory card should work right also with a eMMC??

Thanks
Alessio

Hi,

Did you get it working?
I'm also trying to interface a micron emmc to a lpc4337.
What did you change in the lpc code if i may ask?

Best Regards,

Frank Eggink

If I disable the DMA the eMMC work fine, any suggestione?

Why with the DMA the system doesn't work?

It is not a big problem for the moment, I can continue to develop the code without the DMA, but I want understand what is the cause of the disfunction with the DMA.
