Install the initial version of firmware on the Texas Instruments CC3220SF-LAUNCHXL

These steps are written with the assumption that you have already built the aws_demos project, as described in Download, build, flash, and run the FreeRTOS OTA demo on the Texas Instruments CC3220SF-LAUNCHXL.

  1. On your Texas Instruments CC3220SF-LAUNCHXL, place the SOP jumper on the middle set of pins (position = 1) and reset the board.

  2. Download and install the TI Uniflash tool.

  3. Start Uniflash. From the list of configurations, choose CC3220SF-LAUNCHXL, and then choose Start Image Creator.

  4. Choose New Project.

  5. On the Start new project page, enter a name for your project. For Device Type, choose CC3220SF. For Device Mode, choose Develop. Choose Create Project.

  6. Disconnect your terminal emulator.

  7. On the right side of the Uniflash application window, choose Connect.

  8. Under Advanced, Files, choose User Files.

  9. In the File selector pane, choose the Add File icon [Image NOT FOUND].

  10. Browse to the /Applications/Ti/simplelink_cc32xx_sdk_version/tools/cc32xx_tools/certificate-playground directory, select dummy-root-ca-cert, choose Open, and then choose Write.

  11. In the File selector pane, choose the Add File icon [Image NOT FOUND].

  12. Browse to the working directory where you created the code-signing certificate and private key, choose tisigner.crt.der, choose Open, and then choose Write.

  13. From the Action drop-down list, choose Select MCU Image, and then choose Browse to choose the firmware image to use write to your device (aws_demos.bin). This file is located in the freertos/vendors/ti/boards/cc3220_launchpad/aws_demos/ccs/Debug directory. Choose Open.

    1. In the file dialog box, confirm the file name is set to mcuflashimg.bin.

    2. Select the Vendor check box.

    3. Under File Token, type 1952007250.

    4. Under Private Key File Name, choose Browse, and then choose tisigner.key from the working directory where you created the code-signing certificate and private key.

    5. Under Certification File Name, choose tisigner.crt.der.

    6. Choose Write.

  14. In the left pane, under Files, choose Service Pack.

  15. Under Service Pack File Name, choose Browse, browse to simplelink_cc32x_sdk_version/tools/cc32xx_tools/servicepack-cc3x20, choose sp_3.7.0.1_2.0.0.0_2.2.0.6.bin, and then choose Open.

  16. In the left pane, under Files, choose Trusted Root-Certificate Catalog.

  17. Clear the Use default Trusted Root-Certificate Catalog check box.

  18. Under Source File, choose Browse, choose simplelink_cc32xx_sdk_version/tools/cc32xx_tools/certificate-playground/certcatalogPlayGround20160911.lst, and then choose Open.

  19. Under Signature Source File, choose Browse, choose simplelink_cc32xx_sdk_version/tools/cc32xx_tools/certificate-playground/certcatalogPlayGround20160911.lst.signed_3220.bin, and then choose Open.

  20. Choose the [Image NOT FOUND] button to save your project.

  21. Choose the [Image NOT FOUND] button.

  22. Choose Program Image (Create and Program).

  23. After the programming process is complete, place the SOP jumper onto the first set of pins (position = 0), reset the board, and reconnect your terminal emulator to make sure the output is the same as when you debugged the demo with Code Composer Studio. Make a note of the application version number in the terminal output. You use this version number later to verify that your firmware has been updated by an OTA update.

    The terminal should display output like the following.
