I was seeing probably the same issue with my ITEAD Core A20 board. The ITEAD image is able to read uImage successfully. The sunxi u-boot reads small files ok but fails on kernel/any other larger file.
I would be very interested to find a fix here. I'll try the solutions Hans suggested as I have time. Any additional help is highly valued.
