Problem is that your kernel's blkmem driver is looking at:

^^^^^^^
Which doesn't match where you load your ROM file, romfs.img.

I installed skyeye simulator for GDB/armulator.
So which one are you actually using here?
The trace below looks like GDB/armulator.
On top of that i
installed the uClinux distro also. While installing it dint
throw any error.
But while loading the uClinux in armulator it is throwing an
error and
the kernel is not booting.
(gdb) run
Starting program:
/home/vinay/Documents/NS4Porting_Parvathy/scriptsAndPackages/uClinux-dist/linux-2.4.x/linux
Please provide all the gdb/armulator trace up to this point.
Did it correctly load the boot.rom file?
