Ok I have done the whole process (even made a "make mrproper" to have a
very nice clean uClinux-dist ! I made a "make menuconfig", choosing
Xilinx Vendor and uclinux-auto product. Then I checked the kernel config
option. In the kernel config, what I did exactly is removed Ethernet
Driver and Networking support since I have no Ethernet port on my card.
Then I only changed MTD driver to generic RAM/ROM chip so that it is
able to use my RAM as a romfs ! And after that a classical make dep all.

On the hardware side, I have taken your uclinux_auto as a base config,
all I did was :

- removing Ethernet support and IP.
- replaced DDR controller by a SDRAM controller
- tuned the sram_flash module so that it only controls my SRAM (I have
no flash).
It seems to be allright:  all my "apps" running w/o kernel run
perfectly, so the hardware should ok, memory also.

Moreover, the kernel part work well, since I always get errors AFTER
kernel init sequence.

So I have no idea where to look for the error, if there is one (but
there must be ONE !!!)

Suggestions would be greatly appreciated. Thx

Valentin
