CCS/TMDX5535EZDSP: USB Connection Problem

Part Number: TMDX5535EZDSP

Tool/software: Code Composer Studio

I am having a problem with CCSv5.5 running on Windows 10 laptop similar to what is reported under troubleshooting at  processors.wiki.ti.com/index.php/XDS100#troubleshooting.  When the USB cable from the EZDSP board is plugged into the laptop  the device manager shows that Texas Instruments Debug Probes->XDS100 Class Auxiliary Port and Texas Instruments Debug Probes->XDS100 Class Debug Port is connected.  This should be Universal Serial Bus controllers->TI XDS100 Channel A and Universal Serial Bus controllers->TI XDS100 Channel A which results is an inability to connect and load code and run in debug mode.  This did work at one time.  It does work on my Windows XP laptop.  What to do?

    There are two screenshots on the section of the wiki page you mentioned - the first scenario mentioned by you corresponds to newer versions of the device driver. 

    In this case, I would suspect that CCSv5.5 is not properly working in your Windows 10 - it is not officially tested/supported on it. In this case, I would either try to update its "TI Emulators" component (check the menu Help → Check for Updates) or install CCSv7.4 in a separate directory to validate this configuration. 

    I have Windows 10 and my TMDX5535EZDSP board works just fine, but I am only using versions 6.2 and newer. 

    I will try to think about additional details that may be getting in the way of a good connection and report back. 

    Hope this helps,

    Rafael

    Hi,

    Are you still having this issue? If not, this thread will be closed but feel free to reply to it.  

    I was able to connect to my TMDX5535EZDSP board fine on CCSv5.5 on another Windows 10 machine (Windows 10 Pro / 64 bits / Build 1709) - keep in mind that I am using the XDS100v2 connection and not the older XDS100v1 that was common in previous C5500 boards.

    Regards,

    Rafael

    No this problem has not been resolved.  I am using Windows 10 Home edition, v1709, OS build 16299.309 and Code Composer Studio version 5.5.0.00077.   Mark McKeown had reference a Wiki that describes the problem at processors.wiki.ti.com/index.php/XDS100#Troubleshooting; no solution is shown.  When the EZDSP is connected using USB cable my device manager shows the following.  It should be und:  er Universal Serial Port connections:  TI XDS100 Channel A and TI XDS100 Channel B which does work OK on my Windows XP latop.  What to do?

    Hi,

    Your Device Manager shows the correct drivers for this connection - the Troubleshooting section of the XDS100 page shows the two valid screenshots for this Debug Probe (I just updated the image to improve clarity). Given I have a very similar setup (I just updated to build 309) and it still works fine, I don't see a reason as to why CCSv5.5 can't connect to the kit.

    What does the Test Connection feature say? Is it completely unable to talk to the board or does it throw a specific error? I am trying to isolate the level where the disconnect happens.

    Additional tips and error messages are shown at:

    Hope this helps,
    Rafael

    Karl,

    I haven't heard from you and therefore I am considering you solved this issue already. This thread will be closed but feel free to reply to it in case there are still issues.

    This problem on my Windows 10 laptop has never been resolved.  I have been using my Windows XP laptop to compile and download code.
