5.2 Debug Port Connection With Standard JTAG Connector

Figure 5-3 shows the connection between MSPM0H family MCU SWD debug port with the standard JTAG connector.

For MSPM0H device, users can use XDS110 to implement debug or download function. This list the contents of the XDS110 and provides instruction on installing the hardware.

Standard XDS110

Users can purchase a standard XDS110 on ti.com. Figure 5-4 shows a high-level diagram of the major functional areas and interfaces of the XDS110 probe.

For more XDS110 information, refer to the XDS110 Debug Probe User’s Guide.

Lite XDS110 (MSPM0 LaunchPad Development Kit)

The MSPM0 LaunchPad kit includes a XDS110(Lite) + level shifting circuit. Users can use this debugger to download the firmware into 5V MSPM0 device. Figure 5-5 shows XDS110 circuit.

There are four probes in XDS110:

2.54mm probe for 5V: This port supports the SWD protocol and includes a 5V or 3.3V power supply. Users can connect SWDIO SWCLK 5V GND to the board and download firmware into an MSPM0H device.

2.54mm probe for 3V3: This port supports the SWD protocol and includes a 5V or 3.3V power supply. Users can connect SWDIO SWCLK 3V3 GND to the board and download firmware into 3.3V MSPM0 device.

10-pin probe for 5V: This port supports the JTAG and SWD protocols and includes a 5V power supply. Users can use a 10-pin cable to connect the board and XDS110 and download firmware into a MSPM0H device. Figure 5-6 shows the 10-pin cable.

10-pin probe for 3V3: This port supports the JTAG and SWD protocols and includes a 3V3 power supply. Users can use a 10-pin cable to connect the board and XDS110 and download firmware into a 3.3V MSPM0 device. Figure 5-6 shows the 10-pin cable.

Note:
  • Standard XDS110 support level shift for debug ports, XDS110 just support 5V or 3.3v probe level.
  • TI does not recommend using the XDS110 to power other devices except the MSPM0H MCU because the XDS110 integrates an LDO with limited current drive capability.
