eMMC Initialization Progress in i.MX6S ROM

erickang — Mon, 02 Mar 2015 00:28:04 GMT

Hi All,

I have a problem to boot with eMMC in i.MX6S.

So I want to know how to initialize the eMMC in i.MX6S ROM.

I'm using the i.MX6S revision 1.2 and revision 1.3.

Actually I could know the eMMC initialization progress in u-boot based on <u-boot>/driver/mmc/mmc.c

But It was difficult to analyze the eMMC Initialization progress in i.MX6S ROM.

Could you tell me the eMMC Initialization progress in i.MX6S ROM revision 1.2 and revision 1.3?

Actually I want to know the eMMC Command and Response during the eMMC Initialization in i.MX6S ROM.

Best Regards,

Eric.
