An eMMC5.0 device is used in our system.
We referred to the following URL, and changed a value of "card->ext_csd.rev ".
After booting from SD, OS is able to access the eMMC5.0 device.
However, when our system boots from eMMC5.0 device, that's failed.
If it was eMMC4.5 device, it succeeded.
Does BootROM of MX6 support eMMC5.0?
Does BootROM check EXT_CSD_REV of eMMC?
