Hello!
I've encountered a problem while downloading u-boot-1.1.3 into a FPGA Xilinx
Virtex 2 Pro. I managed to download and use u-boot a week ago but suddenly this
problem appeared. I haven't changed anything since the last downloading and the
FPGA still does work.
Here is an echo of the problem :

The compiling of u-boot was successful but I think that there is a problem with
the address of TEXT_BASE or the sections. I've tried to find an answer to this
problem on the forum but I didn't manage to.
Can you please help me because I really don't know where the problem comes from.
