Our custom imx6 dual lite board using an eMMC v5.1 chip, now I am trying to boot from eMMC(L4.1.15_2.1.0: SPL + u-boot, image, rootfs all write to eMMC). I checked the Reference manual of imx6(IMX6SDLRM.pdf), in the section <188.8.131.52 Expansion device eFUSE configuration>, it described as following:
The boot code supports these standards:
• MMCv4.4 or less
• eMMCv4.4 or less
• SDv2.0 or less
• eSDv2.10 rev-0.9, with or without FAST_BOOT
Does this mean imx6 not support eMMC v5.1?
About the kernel eMMC version patch, I already checked, it is updated in L4.1.15.
Thank you in advance!
