CCS/TMS320F280049C: Need Help with Unresolved Symbols Error After Inserting .syscfg File for CLB into Existing Project

Hello Anthony,

The function CLB_configCounterLoadMatch is part of driverlib.  If you check the properties of the project (right click on the project --> properties) under C2000 Linker, File Search Path, do you see driverlib.lib under "Include library"? Also check under --search_path for an appropriate directory.  driverlib is under C2000Ware 

• For example: Stand alone C2000Ware: C:\ti\c2000\C2000Ware_<version>\driverlib\f28004x\driverlib\ccs\Debug   
• or in the SDK under <install>/c2000ware/driverlib/f28004/driverlib/ccs/Debug/

Edit to mention: XBAR_setCLBMuxConfig is also part of driverlib.

Best regards

Lori

I do not see driverlib.lib in that section. I tried to add it, and got a bunch of similar but different errors: Here is what I saw when I went there:

When I attempted to add driverlib.lib using the file location you provided, I got this error:

EDIT: I should point out that the settings I saw in the first image are the same as my working example, so I am not sure why that would work but the project does not

Anthony,

It looks like there is now two driverlib libraries included (1) one appears to be within in the directory of your project (../driverlib.lib) and (2) the one I just asked you to add (C:\ti.....). 

For the (1) it may be an old version of driverlib.  (2) is definitely not the latest version of driverlib since it is in C2000Ware 2.01.  

Can you try removing (1) from the project directory.  Install the latest C2000Ware and point (2) to that location.

The errors will not occur unless these functions are used in the project.  I suspect the working example does not call these functions.

Note: I also suggest changing the SysConfig to point to the latest C2000Ware (V3.03.00.00).  in order to get latest features supported on this device.

So the CLB TILEs (and the code that sets them up) are almost exactly the same in the working example and the project I am working on. This is why I am confused.

I used the same FSM's, counters, HLC's, etc configured in the exact same way for both. The only difference is the inputs I am using to the TILEs (for example, I am using CMPSS1, 3, 3, and 4 in the real project, and CMPSS 2, 4, and 6 in the working file as the inputs to the tiles through the XBAR).

One major thing I also noticed between the working example and the real project is that the html file for the CLB was not generated in the project but was generated in the working example... could this be a clue?

I experimented by adding an error into a working example.  The .html was not generated in this case as well.

My suggestion is still to make sure the latest driverlib, and sysconfig, is being used.  Have you tried my previous suggestion?   

If you want to dig, for your understanding:

• For the driverlib, in the working directory, you could extract the symbols to see if these functions with unresolved symbols are present, but I would still suggest using the latest driverlib.  To extract a list of the symbols use the archiver which is described in http://www.ti.com/lit/spru513
• In the working example, you can search the project to see if those functions are being used.

I have downloaded the latest C2000Ware 3.03.00, but I am not sure what to do next. It looks like there are several things I would need to change in the properties, but I am not 100% sure what those things are. 

I tried changing it in this tab of the GUI, but it keeps reverting back to version 2 for some reason:

Hi Anthony,

If CCS hasn't been restarted after the new install of C2000Ware it probably hasn't discovered it yet as a product.

I did a search and found this thread which explains how to correct this:

HI Lori,

I noticed that under the project tree, the driverlib folder that is present under all of the example projects seems to be missing for mine:

I am not sure why this is, especially since the code was working before I attempted to add the syscfg file in... but could this be the issue? If so, how do I fix it?

Anthony,

There are two ways to add a library to a project.  It can be (1) linked like any other source file or it can be (2) added to the project options.  I've been walking you through option (2).  

If you want to try the other method, which matches your screenshot of the example, then here is some information on how to do so:

https://e2e.ti.com/support/tools/ccs/f/81/t/612994?CCS-Adding-external-library

http://software-dl.ti.com/ccs/esd/documents/users_guide/ccs_project-management.html#adding-or-linking-source-files-to-project

Either method will work to have the .lib be included in the build of the project.
