DSP cannot be halted

Other Parts Discussed in Thread: OMAP-L137

Hi,

I am developing a project on OMAP-L137 EVM board. I started developing with CCS V4.0.

Since I updated to V4.11 I cannot halt the code execution in debug mode.

I get the following error message:

 

Can somebody help me why this message comes, and how to solve the problem?

Thanks!

    Zoltan,

    Sounds like there might be a driver mismatch between V4.0 and V4.11.  Does spectrum digital provide any updates for this version of CCS? 

    I believe that this message is basically a timeout message. When you try to connect to the device, CCS tries to halt it.  It's basically saying that the driver did a scan and then waited some period of time, but after that time, the CPU wasn't halted.  If the only thing changed is an upgrade to CCS 4.11, this wouldn't be an issue with your board.  it's obviously an issue with the update.

    Regards,
    Dan

    I'm using with CCSv4.1.0 (http://tiexpressdsp.com/index.php/Download_CCS#4.1.0_.28Updated_on_February_2.2C_2010.29 ) with no problem.  Have not tried 4.1.1.

    Just a thought, do you have the Boot switches (SW2) set to Emulation Boot?

    Thanks to all for the reply.

    SW2 is set to Emulation Debug mode.

    I downloaded latest version in the recent days with using automatic update of CCS, and it is V.4.1.1.

    I decided to try the same scenario.  I verified that I could connect with CCS 4.0, and then upgraded to CCS v4.1.1.  I see the same issue.  I can't connect after upgrading.

    It looks like this is possibly an installation bug.  I've filed Bug#SDSCM00035492 for it.

    The only thing that I can recommend at this point is going back to the earlier version ov CCSv4 if possible.

    Zoltan,

    I've been looking into this bug report but have been unable to reproduce it. Are you still having a problem with CCS v4.1.1 and this board?

    I used these steps. Does this correspond with what you would have done?

    • In 4.0.2., create a configuration using an XDS100 and EVM6747.
    • Confirm I can connect to the DSP using the onboard USB emulation connection. I get a GEL script warning, but if I ignore that the connect succeeds.
    • Apply the 4.1.1. update using update manager.
    • Confirm I can connect again.  Works the same as in 4.0.2.

    Thanks for your help in finding the root cause.

    Hi Andy,

     

    In the meantime I switched back to the V4.0. I also found some other bugs in my project that may couse this behaviour.

    Connecting was successful at me as well, but when I started tje sw, and wanted to halt code execution in dsp I got the error message above.

    I am going to upgrade again and  test it with the current version of my code, let's see if it was my bug. May be tomorrow.

    Thanks for your support.

    Regards

    Zoltan
