CortexM3 : Issue when image start address is other than 0x0

I have a very simple CortexM3 based virtual platform example as below

The amba_pv_m2 is connected to a memory in the top. The BusDecoder master port address range is 0x0-0x3FFFFFFF

I have the following C program

#include <stdio.h>

int main(int argc, char *argv[])
{
    printf("Hello!!!\n");
    return 0;
}

and the following make commands

armcc --cpu=Cortex-M3 -g -O2 -c -o hello.o hello.c
armlink --cpu=Cortex-M3 --ro-base 0x00000000  -o hello.axf hello.o

With that when I load the axf into the core and execute, I see the Hello is printed.

Bow I want to load the SW at 0x40000000. For that I did the following chnages

- BusDecoder master port address range 0x40000000-0x7FFFFFFF and make command as

armcc --cpu=Cortex-M3 -g -O2 -c -o hello.o hello.c
armlink --cpu=Cortex-M3 --ro-base 0x40000000  -o hello.axf hello.o

with that the when I run the platform, it stucks somewhere and I am not getting the Hello output.

It seems I am missing some thing here.

Can you guys help me on this ?

Thanks
