2,    Import a project (C:\ti\c2000\C2000Ware_5_04_00_00\driverlib\f28p55x\examples\adc\adc_ex1_soc_software) in CCS

3,  when I click debug button, the CCS  pop out a dialog, ask for  upgrad XDS110, I click update button;  upgrade finish, the software debugging is running in CCS.

4, then I try to import another project(C:\ti\c2000\C2000Ware_5_04_00_00\driverlib\f28p55x\examples\epwm\epwm_ex1_trip_zone)

An attempt to connect to the XDS110 failed.
The cause may be one or more of: no XDS110 is connected, invalid
firmware update, invalid XDS110 serial number, or faulty USB
cable. The firmware and serial number may be updated using the
xdsdfu utility found in the .../ccs_base/common/uscif/xds110
directory of your installation. View the XDS110SupportReadMe.pdf
file there for instructions.
