But the 2nd command (i.e. losetup) returns with the error complaining "/dev/loop1" is not present, but I can see /dev/loop[0..7] files present.

Try loading the module as -

#modprobe loop

I have one more question in the same line (i.e. related to UML). I tried loading an external module (build for ARCH=um type). I am able to load that module only if i've booted UML with following command:

./linux ubda=<raw_file_system_path>

If i pass the mem parameter, i.e.

./linux ubda=<raw_file_system_path> mem=512M

I am not able to load the module. The error that I am seeing is:

overflow in relocation type 11 val a121c3c0 `tun' likely not compiled with -mcmodel=kernel

I tried to load the tun.ko. This holds true for any manually built simple hello_world kind of module too (where i added -mcmodel=kernel parameter in Makefile).

What can be wrong with "mem=512M" parameter? I change the size of mem to 128K to 1G, but nothing works. It just doesn't like "mem" parameter as bootargs.

try compiling it statically

I gave tun.ko as an example. I want to load my own module which is not part of linux kernel.
