What is your kernel command-line? Are you giving your virtual terminal
to the kernel at boot time? Instead of serial port, try directing kernel
output to tty0 with kernel command line option "console=tty0".

If you want to use both your serial terminal and monitor you should edit
your /etc/inittab file for console output on tty0, also.

To be on the safe side, change this line to:
null::sysinit:/etc/init.d/rcS

Try removing these two.

can you add "null" to the beginning of these 3 lines,
again to be on the safe side.

> actually i given ttyS0::askfirst:-/bin/sh
you should try adding: "tty1::respawn:-/bin/sh"

I couldn't see any error in your output. Next time please add
full dmesg output, it helps a lot.

By the way, do you see penguin logo at boot on your lcd/monitor/whatever?

GCC will expect main() to return an int so you might try :

int main (void)
{
}

Also, I don't know what happens in your OS when you return from main(), your AT91's startup
code might restart from reset etc.
