hello everyone,
i need to compile some little assembly code for an ARM PXA-270 processor
running with instruction set V5TE.
i have written arm assembly in the past but using the armulator on a windows
machine.
since i have developed most of the application software for this arm
processor using scratchbox and its toolchains,
i would like to know if there is an assembler for scrachbox, like armasm or
whatever else..
i have found the executable 'arm-linux-as' and tried to do a compile of a
simple hello world program as 'arm-linux-as hello.s, but it failed
miserably:
the program was
*; Exercise 1: A simple program to print**; Hello World! in the
console window**;*
AREA helloW, CODE, READONLY *; declare code area*
SWI_WriteC EQU &0 *; output character in r0*
SWI_Exit EQU &11 *; finish program*
ENTRY *; code entry point*
START ADR r1, TEXT *; r1 -> "Hello World!"*
LOOP LDRB r0, [r1], #1 *; get the next byte*
CMP r0, #0 *; check for 'null' character*
SWINE SWI_WriteC *; if not end, print ..*
BNE LOOP *; .. and loop back*
SWI SWI_Exit *; end of execution*
TEXT = "Hello World!", &0a, &0d, 0 *; string + CR + LF + null*
END
and the compilation errors i got were:
[sbox-DEHTARGET: ~] > arm-linux-as hello.s
hello.s: Assembler messages:
hello.s:0: Warning: end of file not at end of a line; newline inserted

i am using:
the core and libs is 0.9.8 with toolchain 'arm-gcc-3.3.4-glibc-2.3.2
cross'...
thank you in advance for your help
