CC3235MODSF LaunchPad™ Development Kit (LAUNCHCC3235MOD)
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 9) and a 10-pin cable, such as the FFSD-05-D-06.00-01-N (sold
separately from the LaunchPad development kit).

Header J2 follows the Arm

-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.
