2.2.6 Using the XDS110 Debug Probe with a Different Target
The XDS110 debug probe on the LaunchPad development kit can interface to most Arm
®
Cortex
®
-M devices,
not just the onboard target CC3235MODSF device. This functionality is enabled by the J2 10-pin Cortex-M JTAG
connector (see Figure 2-8 ) and a 10-pin cable, such as the FFSD-05-D-06.00-01-N (sold separately from the
LaunchPad development kit).
Figure 2-8. XDS110 OUT Connector (J2)
Header J2 follows the Arm Cortex-M standard; however, pin 1 is not a voltage sense pin. The XDS110 outputs
only 3.3-V JTAG signals. If another voltage level is needed, the user must provide level shifters to translate the
JTAG signal voltages.
1. Remove jumpers on the JTAG signals on the isolation block, including RST, TMS, TCK, TDO, and TDI.
2. Plug the 10-pin cable into J2, and connect to an external target.
J2 follows the Arm Cortex Debug Connector standard outlined in Cortex-M Debug Connectors .
3. Plug USB power into the LaunchPad development kit, or power it externally
JTAG levels are 3.3-V ONLY
