I don't know what you intend to link with in your code. But if you are trying to use fasmarm to assemble code you can try with the ELF example.

Code:

        format ELF executable
        entry start

        segment readable executable

start:  mov     r0,0
        add     r1,pc,hello-$-8
        mov     r2,hello_len
        swi     0x900004
        mov     r0,6
        swi     0x900001

hello:  db      'Hello world',10
hello_len=$-hello

        ;dummy section for bss, see http://board.flatassembler.net/topic.php?t=3689
        segment writeable

Or the DWARF example which is also included in the fasmarm download.
