Known Issues and Modifications
4. CCS will error out with the below dialog complaining of a DAP connection error to the target core.
a. Hitting retry results in the same error message
Workaround 1: After the connection issue is encountered, users can unplug the USB host connection to the
XDS110 emulator through USB port (J28) and then plugin the USB cable again. This power cycles the XDS110
and will clear up the connection error.
Workaround 2: After the connection issue is encountered, users can toggle TRSTSN through the XDS110
debug command-line utility xds110reset found in the CCS XDS110 utility directory.
In the Windows OS installation, for a default installation of CCS version 10.11, this tool is found in the directory
C:\ti\ccs1011\ccs\ccs_base\common\uscif\xds110>
This command can be executed on the Windows command prompt/terminal when the embedded XDS110 is
powered on and connected to the host PC. A similar tool is available under the Linux OS install of CCS.
