Hello,
You can't jump directly into uImages. It would work with a zImage, butOn Tue, Feb 21, 2012 at 08:38:24PM +0200, George Stefan wrote:

how do you get your zImage from the sd card without the help of the
bootloader? Well, you could link barebox and a zImage together, but then
you'll realize that the internal ROM code is quite slow when reading
data from SD cards (unless there are ways to tweak this, I don't know)
What are your goals trying this?
