2.5.1.1 HW Prerequisites

  • Windows 10 64-bit or Ubuntu 18 (or higher) 64-bit operation system
  • Latest Chrome web browser
  • Installation of Simplelink Wi-Fi Toolbox
  • LP-EM-CC35X1
  • LP-XDS110 or LP-XDS110ET debugger for SWD communication

The LP-XDS110 enables direct communication to the CC35xx 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 flashing the application image.

Note:

When using Simplelink Wi-Fi Toolbox, the default flash populated on the board is IS25WJ064F. Users must choose the correct flash option when prompted by the GUI.

LP-EM-CC35X1 supports a variety different flash options. The list of supported flashes can be found in the SDK release notes on CC3551E product page.

For LP-EM-CC35X1ET users only, it is also important that the correct PSRAM type is selected. Users must select Stacked 8MB AP Memory. Users not using LP-EM-CC35X1ET must select No PSRAM for this option.
