Hi,
Does the i.Mx6 SoloLite processor support "e.MMC 5.0 with HS400 Interface" ?
After studying few posts in the community, I could not arrive to a conclusion:
Re: i.mx6 with eMMC 5.0 SDR or DDR interface?
Does i.MX6 quad core processor support eMMC 5.0 HS400 interface
Let me know your comments on this.
Thanks.

Dear Igor,
For your above mentioned comments:
"Hi Pankaj

igor"
Now, not considering the HS400, will the SoloLite Processor support eMMC 5.0 ?
Regards,
Pankaj Rana
Hi Pankaj
not, according to IMX6SLRM sect.54.1.1 Features
..
• Compatible with the MMC System Specification version 4.2/4.3/4.4/4.41

Hi Igor,
Few clarifications on eMMC interfacing with SoloLite Processor:
iMX6SLRM
Chapter 5: Fusemap
Table 5-5. MMC/eMMC Boot Fusemap
0x450[15:8] Port Select:
(BOOT_CFG2) 00 - uSDHC1
01 - uSDHC2
10 - uSDHC3 (eMMC4.4)
11 - uSDHC4
Does that mean that eMMC4.4 is supported only on uSDHC3 ?
Whereas in Chapter 8:System Boot , section 8.5.2.1 , it is mentioned "All USDHC ports support eMMC4.3 and eMMC4.4 fast boot."
Also in Table 8-15. :
eMMC Reset Enable - "eMMC reset enabled via SD_RST pad (on USDHC3 and USDHC4 only)"
Please clarify this, at the moment there is uncertainty regarding the eMMC usage and USDHC port selection.
Many Thanks.
