I followed the SOPC builder tutorial which you can find in the link below:
http://www.usna.edu/ee/ee462/manuals/tut_sopc_introduction.pdf I compiled the assembler code given in the tutorial:
.include "nios_macros.s"
.equ Switches, 0x00001800
.equ LEDs, 0x00001810
GFUNC _start
movia r2, Switches
movia r3, LEDs
loop: ldbio r4, 0(r2)
stbio r4, 0(r3)
br loop
BREAK
however I am gettting the compilation error as:-
