CC3235MODSF LaunchPad™ Development Kit (LAUNCHCC3235MOD)
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 5), which is a simple and low-cost debugger that
supports nearly all TI Arm device derivatives.
Figure 5. XDS-110 Debug Probe
The dotted line through J101 shown in Figure 5 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.
