Hi,
Thanks for your replies Peter Pearse and Catalin Marinas.

I use
<U-Boot dir>/tools/mkimage -A arm -O linux -T kernel -C none -a 0x7fc0 -e 0x8000 -n u-linux -d <Kernel dir>/arch/arm/Image u-linux
Worked like a charm!
I then had to copy the kernel to SDRAM 0x7fc0 and boot it using:
cp 0x36000000 0x7fc0 <kernel_size> bootm 0x7fc0
2. I then tried to use the base.cramfs filesystem provided in arm.com:
http://www.arm.com/linux/linux_download.html
I used mkimage to append a header and flashed it at 0x36200000. Copied the same to SDRAM, 0x04000000. I changed the bootargs values using setenv, but, was not sure as to what values I need to give.
setenv bootargs root=/dev/mtdblock0 mtdparts=versatile:0x65d050@0x04000000(cramfs) ip=none mem=128M console=ttyAMA0 video=vc:1-2clcdfb:
I then tried to boot the kernel with the ramdisk:
bootm 0x7fc0 0x04000000
I got the following output:

Why is it trying the floppy? Is it trying the external memory card?
I did check the boot log to the 2.4.19-rmk6 kernel provided in the NOR flash, and it loaded ramdisk drivers etc. I have used the config-versatile-pb file as provided in arm.com site, which does not have support for ramdisk by default. I did try enabling ramdisk support, but, I ended up with the same output as above. The ramdisk by default is 4 MB in the kernel, but base.cramfs given in arm.com is 6 MB. I even tried changing the ramdisk size in kernel CONFIG to 8 MB, but, no change in the output.
I'd appreciate any feedback for the above, and any help in getting the filesystem mounted, so I can start playing with the shell.

Thanks again for your help,
