Dear team,

 

I would like to ask about eMMC BOOT of i.MX6SX.

My customer is trying to boot-up i.MX6SX from eMMC.

And they saw that boot cannot be done in the following case.

- LCD1_DATA04(SRC_BOOT_CFG04)=H, LCD1_DATA15(SRC_BOOT_CFG15)=H

For the other settings such as below, the boot from eMMC can be done.

- LCD1_DATA04(SRC_BOOT_CFG04)=L, LCD1_DATA15(SRC_BOOT_CFG15)=L

- LCD1_DATA04(SRC_BOOT_CFG04)=L, LCD1_DATA15(SRC_BOOT_CFG15)=H

- LCD1_DATA04(SRC_BOOT_CFG04)=H, LCD1_DATA15(SRC_BOOT_CFG15)=L

They are using eMMC 4.41 compliant chip, and they believe that FastBoot mode and DDR mode can be enabled simultaneously for i.MX6SX eMMC boot.

Is it true?

If yes, please let me know what they should do to achieve enabling both of FastBoot mode and DDR mode.

 

Thanks,

Miyamoto
