I am trying to communicate with an eMMC flash memory. I already have a library for connecting to MMC flash memory which is based on SPI protocol. In new eMMCs SPI protocol is not supported. I want to ask is the protocol in MMC different to eMMC fundamentally? To be more clear can I just send and receive the same data which was send in SPI mode just in parall to eMMC to get the same result?

Thanks

eMMC and MMC are largely interchangeable. However, eMMC and latterly MMC no longer support SPI. If you solder eMMC to a board and plug it into a card reader it will work just like an SDCard. However, the protocol is native to MMC and SPI won't work.
