These steps are written with the assumption that you have already built the aws_demos project, as described in Download and Build Amazon FreeRTOS for the Texas Instruments CC3200SF-LAUNCHXL.

  1. On your Texas Instruments CC3200SF-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 and from the list of configurations, choose CC3220SF-LAUNCHXL, then choose Start Image Creator.

  10. In the File selector pane, choose the Add File icon .

  11. 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.

  12. 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 AmazonFreeRTOS/demos/ti/cc3200_launchpad/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.

  18. Under Signature Source File, choose Browse, choose simplelink_cc32xx_sdk_2_10_00_04/tools/cc32xx_tools/certificate-playground\certcatalogPlayGround20160911.lst.signed.bin, and then choose Open.

  19. Choose the button to save your project.

  20. Choose the button.

  21. Choose Program Image (Create and Program).

  22. 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:
