Error: Building assembly only project

Mike Meier
Prodigy 30 points

Hi there!

 

We have to build an assembly only project in our school. When we try to build our code, we get some errors.

What we did:

 

  • Build a new CCS Project
  • Selected the checkbox "Treat as an Assembly-only project"
  • Choosen the linker command file "lnk.cmd"
  • Added a new file named "main.asm"

 

Code inside main.asm:

main:
    mov #1000, AR0
loop1:
    rpt    #65000
    nop
    sub #1, AR0
    bcc loop1, AR0 != 0
    xor #0x2000, st1_55
    B main
.end

 

When we build it we get this command output:


**** Build of configuration Debug for project BlinkLED ****

Has anybody an idea why it don't run correctly. Is so boring. We didn't found a tutorial or other discription

on TI website!!

 

Thanks.

    Hello Mike,

    I usually use C, so I am not sure if this will work:

    Try to rename main to _main and add " .def _main" to main.asm.

    Hi Jiri

    I tried it out. But there are still errors. The new main.asm:

     

    .def _main

    _main:
        mov #1000, AR0
    loop1:
        rpt    #65000
        nop
        sub #1, AR0
        bcc loop1, AR0 != 0
        xor #0x2000, st1_55
        B _main
    .end

     

    and the errors:


    **** Build of configuration Debug for project BlinkLED ****

    Hi Mike,

    there has to be a space before .def.

    Hi Jiri

    Thanks a lot. It runs now!

    The source for main.asm:

    ;******************************************************************
    ;    desc: simple demo blink code
    ;    autor: Mike Meier
    ;    date: 27.05.2010
    ;
    ;    additional information:
    ;    with standard lnk.cmd builded (all lines begins with '-' commented for asm!)
    ;******************************************************************


     .def start_up        ;define a start function definieren (entry-point) / important: space before point
     
     .text                       ;save the following code in  ROM    PAGE 0 / important: space before point
    start_up:
        mov #1000, AR0
    loop1:
        rpt    #65000
        nop

        bcc loop1, AR0 != 0

        B start_up
    .end

     

    AND write under Project Properties ( [Tool Setting] > [C5500 Linker] > [Symbol Management:] > [Specify program entry point…]) your
    start function name (ex. start_up)
