TMS320F28388D: CLB Counter not counting

Wilko Moritz

Part Number: TMS320F28388D
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE

Tool/software:

Hello,

I am currently working on a project with the Configurable Logic Block (CLB). To get started, I followed the recommendations from the CLB User Guide and edited a CLB Tile using the Sysconfig Tool.

Now, I want to test it using the GTK Wave Viewer. After opening the VCD file in the GTK Wave Viewer, I can see that the Match_Ref values are correct, but the counter_output always stays at 0.

In search of my mistake, I also opened the VCD file for Example 9 (Timer). However, even there, I can't see the counter incrementing—the counter_output remains at 0.

As you can see in the image above, the counter_output stays at 0 the entire time.

Any input on what could be wrong would be greatly appreciated!

Best regards,
Wilko

Edit:

I have some new information concerning my problem:

I have found that my counter starts to count if reset is high. 

I would like it the other way around. How do I change this ?

There is a similar Post on TIE2E: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1355821/tms320f280049-clb-simulation

In this Post  (I hope this is the correct Luke Jones) said the solution is implemented in the C2000 Version 5.03. 

I am using this version and the problem persists. He also gave some source code that should fix this problem. This did not work either.

I hope this helps to narrow down my problem.

Best regards,

Wilko

    Hi Wilko,

    I am downloading C2000Ware version 5.03 on my side to confirm whether this was fixed or not.

    The manual fix I listed in that thread should still work. Did you confirm that you're using the paths for C2000Ware 5.03 and not 5.02 when adding the manual fix?

    Thank you,

    Luke

    Good morning Luke,

    You are correct, the manual fix is working—I had simply forgotten to run the SystemC_Compiler file.

    However, it would still be helpful if this issue could be patched in C2000Ware 5.04. I'm working on a multi-person project, and having this fix in place would make it much easier to ensure that everyone is using the exact same version of C2000Ware, and I wouldn’t have to manually correct it for everyone.

    Best regards,
    Wilko
