XDS110 Debug Probe

Figure 12. dbgjtag Screenshot JTAG Integrity Test

The IR and DR scan paths are tested separately. Look for both to have succeeded to know that the debug
connection is working correctly. This is the test performed by the Test Configuration button in CCS.

How to test the debug connection for SWD mode:

dbgjtag -f @xds110swd -S integrity

The output for a successful test appears as in

Figure 13
