Hi!

I still have the error, my asm sour file is main.S, the code from a NIOSII tutorial:

.include "nios_macros.s"

.equ switches, 0x41020

.equ leds, 0x41030

.global main

main:

movia r2, switches

movia r3, leds

loop:

ldbio r4, 0(r2)

stbio r4, 0(r3)

br loop

but: alt_main.c:154: undefined reference to `main'

:(
