3.1.3.1 Radio Tool BP-CC3301 Hardware Setup

Radio Tool is a GUI-based tool for RF evaluation and testing of CC33xx designs during development and certification. The tool enables low-level radio testing capabilities by manually setting the radio into transmit or receive modes. Usage of the tool requires familiarity and knowledge of radio circuit theory and radio test methods. To preform conducted RF testing on the BP-CC3351, refer to Section 2.5. Note that a rework can be needed.

The user can download this tool from the CC330x product page on ti.com.

HW Prerequisites

  • Windows 10 64bit/ Ubuntu 18 (or higher) 64bit operation system
  • Latest Chrome web browser
  • Installation of Simplelink Wi-Fi Toolbox
  • BP-CC3351
  • LP-XDS110 debugger for SWD communication

The LP-XDS110 enables direct communication to the CC3351 device via the SWD interface. This allows external tools, such as the Radio Tool, to send commands directly to the device without the use of an embedded host.

Testing with LP-XDS110

To use the LP-XDS110 with the BP-CC3351, connect the 20-pin LP-XDS110 connector (J11) on the BP-CC3351 to the corresponding connector on the LP-XDS110 (see Figure 4-7). Make sure that the jumper on the LP-XDS110 (labeled TGT VDD) is in the EXT. configuration, as shown in Figure 4-7. This verifies that the target voltage for the JTAG signals are sourced from the BP-CC3351 (which is 1.8V) instead of the default LP-XDS110 target voltage (3.3V).

Power supply for the BP-CC3351 comes from the LP-XDS110 in this case, but there can be usage scenarios where additional current is needed from the USB connection (J7).
