I took a quick look at your .zip file. Many problems:

1) The code you posted is in main.cpp, not in a .c file. Any function name you want
to reference in the DSP/BIOS config has to be declared in a .c file, not a .cpp, to
avoid "name mangling" (yes that's right, look that term up on Google).

2) Your .zip file contains no linker command file (.cmd). Since your number of files
and memory usage should be very small at this point, that's Ok for now. Later you
will need one.

3) There are several labcfg1.obj and labcfg1_c.obj files, but no matching source
files.

Overall this project looks like a mess. But hopefully if you fix #1 above (rename to
main.c) you can get the thing to build. My suggestion for the time being is to not
have *any* .cpp files anywhere near CCS. You are not ready for that yet.

Hello Balasubramanian,
I agree what Jeff said. Furthermore, you can check the Task Manager if
_our_task's been included, then from there you need to make sure it is
also included in the Task function.
If you get the right .map file, and it also pointed out the task in
there, so it should be working.
Good luck !
Tung

Does "_sem" show in the .map file? If not then you are looking at the
wrong
lab1cfg.obj file.

Richard points out that lab1cfg.obj probably didn't compile. Do you see a
lab1cfg.obj file? Does it have today's date and time? Is lab1cfg.c listed
in your
source view window?

No point, your GUI is not the issue. If the .map file shows '_sem' but not
'_our_task' then you have a mismatch. Either Richard is correct -- your lab1cfg.c
file does not compile because "sem" is not declared -- or you should show where sem
is declared.

This is a basic compile/link issue. My guess is that another group did this lab
before you and somehow you've got a mix of old and new files, or a filename has been
changed, or other mismatch. Be sure to try "Build All" option.

Does "_sem" show in the .map file? If not then you are looking at the wrong
lab1cfg.obj file.

lab1cfg.obj got created... what i notice is this in lab1.map it says _our_task is undefined

address name
------------


0000d020 _memcpy
UNDEFED _our_task
0000cda4 _our_task__Fv
0000f52c _rtdx_buffer_state
0000f54c _rtdx_mon_state


Do you see as UNDEFED... This is what i see in the map of lab1.map...


Please let me know....

balasubramanian,

This could be a 'forward reference' problem.

A possible fix is to move the our_task() declaration before the
#include "lab1cfg.h"

Note that it has _our_task in the list of functions. This is part of the include files.... Still i get this compile error...

Jeff

The error is

undefined symbol

_our_task \Debug\lab1cfg.out
lab1 was my project name... I opened the lab1.cdb file and added this function as _our_task to the TSK0 that was inserted as task to the scheduling option. It does not recognise the our_task for whatever reason.....
