USB mass storage gadget on SAMA5D2

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.
Regards,
Zixun
