What Avnet board are you using? I can upload my file... How much ram do you have? Are you using the S3 Eval? I am using the V-II Pro Eval (32MB DDR)

Hi Greg,
I happen to have the same (i guess) board from Avnet and got into the same
problem: "KERNEL panic: VFS....."
I tried with "Generic uClinux RAM/ROM filesystem support" in MTD Mapping
section, but the problem persists.
In vendor/product selection of "make menuconfig", what did you select?
I selected "(Xilinx) Vendor / (uclinux-auto) Xilinx Products. Is this the
same as you? Did you only turn on "Generic uClinux RAM/ROM filesystem
support" with everything else left as default?
I think the best way is to see your .config file.
Could you please post your .config file in "linux-2.4.x/.config"?
I'd like to compare it with mine to see what is the difference.
Thank you very much,
Taeweon
