Debug Interfaces¶
The CC23xx or CC27xx platform supports SWD interfaces. Debug probe that support SWD like the TI XDS110 can work natively with the CC23xx or CC27xx. The hardware resources included on the devices for debugging are listed as follows. Not all debugging functionality is available in all combinations of debug probe and IDE.
Flash Patch and Breakpoint Unit (FPB) - 6 instruction comparators, 2 literal comparators
Data Watchpoint and Trace Unit (DWT) - 5 watchpoints on memory access
Instrumentation Trace Macrocell (ITM) - 32 x 32 bit stimulus registers
Trace Port Interface Unit (TPIU) - serialization and time-stamping of DWT and ITM events
XDS110 Debug Probe¶
The CC23xx LaunchPad support a 20-pin LP-EM debug connector, and the XDS110ET LaunchPad is the assumed debug probe for most development.
The XDS110 is the latest entry level debug probe (emulators) for TI embedded processors. Designed to be a complete solution that delivers JTAG and SWD connectivity at a low cost, the XDS110 is the debug probe of choice for entry-level debugging of TI microcontrollers, processors and SimpleLink devices. Also, both Core Processor and System Trace are available for all Arm and DSP devices that support Embedded Trace Buffer (ETB).
It is also possible to buy the XDS110 JTAG Debug Probe or use the XDS110 existing on-board another SimpleLink LaunchPad.
Segger J-Link Probes¶
The CC23xx or CC27xx platform also supports Segger J-Link Probes. These probes support
standard debug and flash operations on the CC23xx or CC27xx. To create a J-Link compatible image,
the crc_tool resource included in {SDK_INSTALL_DIR}/tools/common/crc_tool should be
used to calculate the CRC. This can be done through the use of a post-build step.
The add_crc_to_elf_file_ccfg section, provides details on how to use the
crc_tool along with code snippets showcasing its use.
The J-Link Real Time Transfer (RTT) feature may be used with the CC23xx or CC27xx platform when using a J-Link probe by following the guidance outlined in the Segger Real Time Transfer (RTT) website.
