IcePick_C: Error initializing emulator: (Error -260 @ 0x0)

CCS Test Connection Failed with 'SC_ERR_XDS110_OPEN' and '-260'

Other Parts Discussed in Thread: LAUNCHXL-F280039C

Hi team,

I am going to load some programs into the LAUNCHXL-F280039C in Windows 10 OS.

What I encounter is almost the same phenomenon as IcePick_C: Error initializing emulator: (Error -260 @ 0x0) - Code Composer Studio forum - Code Composer StudioTm︎ - TI E2E support forums, except that I am using Windows 10 OS.

Is there any common causes on Windows OS?

Also, the "Test Connection" works well after I plug in the USB cable. However, after about half a minute (several "Test Connection" success), it fails with 'SC_ERR_XDS110_OPEN' and '-260'. Re-plug it , success, then fail... Actually, I can load the programs into the LAUNCHXL-F280039C only within a short time after I plug in the USB cable.

Thanks for help in advance.

Best Regards,

Steven

    This is a common error known as a "host connection error". Basically, the debugger is unable to establish communication with the XDS110 debug probe. The root cause can vary greatly. Please see the subsection called "host connection error" see the below article for more details:

    In your specific case it appears it works for awhile an then fails. This leads me to believe that you have an unstable USB connection between the PC and the probe. Try using a different USB port. If using a USB hub, try a direct USB connection to the PC instead. Perhaps try a new USB cable.

    Hope this helps

    As per your advice, I have tried different USB ports, different cables, different LAUNCHXL-F280039Cs. However, the same issue occurs for all cases. 

    I have also tried reinstalling the Windows device drivers, but it doesn't help.

    Best Regards,

    Is the issue specific to just one particular PC? 

    Are you doing anything in particular when the host connection error occurs (either on the PC or in CCS)? If you connect with CCS and then just do nothing (don't run the target or anything), will the error still happen in half a minute?

    I will have a try with another PC later and let you know the result.

    I don't think I am doing anything in particular.

    Yes. The error still happens. It may not be exactly half a minute but it does occur some time later.

    Yes, please confirm. I suspect the issue is local to your machine.
