Hi Mihai, Thanks for your reply, although it's meaningless.
As I said, what we need is block level access to eMMC, in order to modify partition table or access files of rootfs, SAM-BA can't do it. Besides SAM-BA can only be launched when eMMC is empty, no way to launch SAM-BA from u-Boot unless erase bootstrap. I've also tested with a SD card on SAMA5D27-WLSOM1-EK, which failed with the same symptom (support case 01275010) To reduce unknown factors we can use this platform for testing.
