2.2.2 XDS110-Based Onboard Debug Probe
To keep development easy and cost effective, TI's LaunchPad development kits integrate an onboard debug
probe, which eliminates the need for expensive programmers. The CC3235MODSF LaunchPad has the
XDS-110-based debug probe (see
Figure 2-4 ), which is a simple and low-cost debugger that supports nearly all
TI Arm device derivatives.
Figure 2-4. XDS-110 Debug Probe
The dotted line through J101 shown in Figure 2-4 divides the XDS110 debug probe from the target area. The
signals that cross this line can be disconnected by jumpers on J101, the isolation jumper block. More details on
the isolation jumper block are in
Section 2.2.3 .
The XDS110 debug probe also provides a "backchannel" UART-over-USB connection with the host, which can
be very useful during debugging and for easy communication with a PC. More details can be found in
Section
2.2.4 .
The XDS110 debug probe hardware can be found in the schematics in Section 7.2 and in the CC3235MOD
LaunchPad hardware design files .
