Having received two F280049C Launchpad boards both with identical serial numbers, I needed to change the serial number of at least one in order to connect via XDS110 JTAG probe if I wanted CCS to connnect to both simultaneously. In the project properties, there is the option to connect to the Launchpad using its serial number, thereby ensuring that CCS always connects to the intended board. It is still unclear to me whether the serial number is associated with the Launchpad or the XDS110.
After searching around I found the following info:
1. Go to directory C:\ti\ccs1100\ccs\ccs_base\common\uscif\xds110
Replace the 1100 in ccs1100 with your version of CCS
2. run command from command line: sdsdfu -e to find out the current serial number
3. run command from command line: xdsdfu -m to put xds110 in DFU mode
4. run command from command line: xdsdfu -n xxxx -r where xxxx is your four digits to replace the last four digits of the current serial number
5. run command from command line: xdsdfu -e to verify new serial number

i can only hope this relieves your anxiety.
