Q: I can't program my LaunchPad; the IDE can't connect to target. What's wrong?
A: Check the following:
• Is the JTAG switch (S101) in the correct orientation?
– Switch to left for XDS110-ET onboard debugger
– Switch to the right for external debugger connection
• If using an external debugger, is USB power provided?
• Check the debugger settings: change to Serial Wire Debug (SWD) without SWO
– Under targetconfigs double-click the *.ccxml file
– Click the Advanced tab at the bottom
– Click on Texas Instruments XDS110 USB Debug Probe
– Under Connection Properties, change SWD Mode Settings to Use SWD Mode with SWO Trace
Disabled

– When the settings of Port J (PJSEL0 and PJSEL1 bits) are changed, full JTAG access is prevented
on these pins. Changing to use SWD allows access through the dedicated debug pins only.
• If even this can't connect, reset the device to factory settings
– Click View → Target Configurations. CCS shows the target configuration.
