2.5 Evaluation Setup

The CC35xxE Launchpad is designed to work primarily with the LP-XDS110, which provides SWD and UART interface to external PC. The SWD interface is used for flashing the compiled image to the CC35xxE and basic debugging, while the UART is used for serial terminal access.

The LP-XDS110 or LP-XDS110ET can easily integrate with the LP-EM-CC35X1 by connecting the 20-pin LP-XDS110 connector (J7) to the corresponding connector on the LP-XDS110 (see Figure 2-27). Make sure that the jumper on the LP-XDS110 (labeled TGT VDD) is in the EXT. configuration, as shown in Figure 2-27. This verifies that the target voltage for the JTAG signals are sourced from the LP-EM-CC35X1 (which is controlled by VIO1) instead of the default LP-XDS110 target voltage (3.3V).

WARNING: To verify proper functioning of the board, the LP-XDS110 and USB-C power cable from the LP-EM-CC35X1 must be connected to the same computer. Do not connect the USB-C cable to a wall outlet or different computer.

To properly interface UART signals for serial terminal interface, verify that jumpers J4 and J6 are placed in the correct configuration. See Section 2.1.3.

For more information on the 20-pin LP-XDS110 connector and the available pinout, see Section 2.1.1.
