Hello,
U-Boot is already running in my board. I configured the Flash, SDRAM, SRAM,
FEC (ethernet) and console. Apparently all is working and I can trace the
code just before the call in order to transfer the control to Linux, that
is:
      (* kernel) (kbd, initrd_start, initrd_end, cmd_start, cmd_end);
There it is supposed the U-Boot finishes its operation and then the Liinux
kernel takes the control, but it hangs.
I did the Linux image with entry address and load address 0x0. U-Boot can
check the Multi-image correctly.
So I don't know where the problem is. I think the problem is in the Linux
image, not in U-Boot, I can not assure it.
I can't trace the Linux booting because it hans at the beginning, even the
console is not initialized.

Could anybody help me?

One question more,  I wouldn't have to configure the memories again, I
mean, Linux doesn't participate in the configuration of the memories
because U-Boot has already done, right?

Thanks,

Raúl Moreno
