Many users have a preferred external debug probe and want to bypass the XDS110-ET debug probe to program the MSPM0 target MCU. The bypass is enabled by jumpers on isolation block J101 and the connector J103. Using an external debug probe is simple, and full JTAG access is provided through J103.
- Remove jumpers on the JTAG signals on the J101 isolation block, including NRST, SWDIO and SWCLK.
- Plug any Arm debug probe into J103.
- J103 follows the Arm Cortex Debug Connector standard outlined in Cortex-M Debug Connectors.
- Plug USB power into the LaunchPad development kit, or power the kit externally.
- Make sure that the jumpers across 3V3 and GND are connected if using USB power.
- External debug probes do not provide power, the VCC pin is a power sense pin.
- For more details on powering the LaunchPad development kit, see Section 2.4
