I am trying to debug simple program (hello_world). I run the QEMU as,

>  qemu-system-nios2 -s

and run the nios aware gdb as,

> nios2-elf-gdb hello

and than in gdb I attach it to QEMU by,

> target remote localhost:1234

but when I type "continue" in gdb window, it just hangs and prints nothing. I  
tried to set breakpoint but still the same issue

hello executable is generated as,

> nios2-elf-gcc -g -o hello hello.c

Where hello.c is a simple program which prints "hello world"

I am not sure if I am doing something wrong here...
