5.2 Debug Port Connection With Standard JTAG Connector

Figure 5-3 shows the connection between MSPM0L family MCU SWD debug port with the standard JTAG connector.

JTAG and MSPM0L Connection Figure 5-3 JTAG and MSPM0L Connection

For MSPM0L device, use XDS110 to implement debug/download function. Here, list the contents of the XDS110 and provides instruction on installing the hardware.

Standard XDS110

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.

More standard XDS110 information, see the XDS110 Debug Probe User's Guide.

Lite XDS110 (MSPM0 LaunchPad™ kit)

The MSPM0 LaunchPad kit include the XDS110-ET (Lite) circuit. Use this debugger to download the firmware into MSPM0 device. Figure 5-5 shows the XDS110-ET circuit.

There are two probes in XDS110-ET:

2.54mm probe: This port supports the SWD protocol and includes a 5V or 3.3V power supply. Connect the SWDIO SWCLK 3V3 GND to the board and download firmware into the MSPM0L device.

This probe supports EnergyTrace™ technology so a user can use this circuit to measure power consumption precisely in real time.

More information on EnergyTrace technology, visit the EnergyTrace Technology tool page.

10-pin probe: This port supports the JTAG and SWD protocols and include a 3.3V power supply. Use the 10-pin cable to connect the board and XDS110-ET and download firmware into the MSPM0L device. Figure 5-6 show the 10-pin cable.

Note:
  • Standard XDS110 support level shift for debug ports, XDS110-ET just support 3.3V probe level.
  • TI does not recommend using the XDS110 to power other devices except the MSPM0L MCU. The XDS110 integrates an LDO with limited current drive capability.
  • XDS110-ET 2.54mm probe does not support the JTAG protocol.
  • XDS110-ET 10-pin probe does not support EnergyTrace technology.
