eMMC coding using CCS

USHA M

Other Parts Discussed in Thread: AM3352

Hi,

I want read the CID register of eMMC device connected on MMC1 interface of AM3352 using CCS.

What should be the command that has to be used ?? Is it CMD1 for OCR followed by CMD2 for CID contents or some other commands are there ??

What ever sequence mentioned for MMC card initialization and detection is followed. Is any other sequence that has to be followed for eMMC device??

Thanks,

Usha

Hi Usha,

You can download the latest eMMC standard for free directly from JEDEC, after registration: http://www.jedec.org/standards-documents/docs/jesd84-b451

Thanks for your information.

I have connected eMMC device to MMC1 interface of AM3352.

What should be the register configuration to enable MMC1 module(PRCM register settings)??

Sorry, I can't help with software. Perhaps you should tell what software you are using.
