running code in two different areas

senthil raj

Hello all

I want to run project which has two assembly files added to it.I am giving an example below.I have two assembly files named biggest.a and biggest_seg.a
The program will find the biggest number between 2 numbers.
A part of the code is in the biggest_seg.a file.I want to give a Branch to the label "compute" in the file biggest_seg.a from biggest.a and it is not working.

when i build the program i am getting the error
biggest.a(12): error A45: UNDEFINED SYMBOL

the program looks like this


biggest.a

	Area biggest, code, AT 0x40000000


value1 EQU 34
value2 EQU 45
	Entry

	mov r5,#value1
	mov r1,r5
	mov r2, #value2
	Cmp r1,r2
BEQ compute ;target is in biggest_seg.a
	Mov r1,r2
	SWI     0x123
