Undefined Symbol

Hi,

I guess you're facing some linking issues. This usually happens due to:

1. Improper initialization or

2. You forgot to add a .c file or a library to your project

I have the same problem:

error: unresolved symbols remain
error: errors encountered during linking; "FlashingLeds.out" not built

I have checked that DSP2803x_GlobalVariableDefs.c are in the project folder tree.

Other than that I have no clue what to do :)

Hi Yngve!

If you mean example project from folder

ti\controlSUITE\development_kits\TemplateProjects\FlashingLeds-F28035_v1.0\ 

I haven't problems with one. Perhaps you have imported it  to your CCS workspace incorrect. You need to do following: Project>Import Existing CCS Eclipse Project>Browse etc. Also at "Import Window"  fill check box "copy project into workspace". You can check a content of your project folder through my screenshot:

Hello Igor and thank you for your response.

The project is this one: C:\TI_F28xxx_SysSW\FlashingLeds\FlashingLeds

I have "fought" a dozen errors, mostly about missing include files which I have move around and updated, but also a bunch of other path-errors to files which are not in their default location and so on. In one file I even had to delete som code (watchdog in DSP2803x_CodeStartBranch.asm).

So, finally after fighting through all these errors this is what stands in between me and what I hope will become an out-file.

My project folder is currently 83 files long due to all the include files I heaped together in the project root (mostly header files) - but I think you did it in a more neater way by referring to their location in the include-folder.

anyways, what is an obj-file and why cant I "read" it? It seems like binary code, and any search of the undefined symbols in the project returns nothing. Hence i have no idea what it means and what I can do about it.

It is slightly frustrating not getting anyting to build or run when I spent 400 dollars on a kit which had a bunch of samples with it.

Thanks, Gautam and Igor!  That got it linked!

The next task it get the code into the Piccolo.  Debug does not work for me.  I guess I need to start digging through help stuff to see what I am doing incorrectly.

Hi Guys!

Steve,

you are welcome to forum if new issues will appear. Good luck.

Yngve, 

do not panic;-). This thread is closed. Create please own new post with your issues (NEW POST button). And my first recommendation is download & install please controlSUITE if you didn't do that still.

Regards,

Igor
