3.3 CCS Environment Configuration

  1. Unzip FreeRTOS™ package (download from freertos.org) in a folder, and add variable in dialog from CCS->Window->Preferences->Code Compose Studio->Build->Variables.

    Variable name: FREERTOS_INSTALL_DIR

    Value: C:\ti\FreeRTOSv202107.00 (unzip folder address)

  3. Open Workspace in CCS.

    If there is no available workspace when CCS is started, a dialog will pop up to ask to select a directory as workspace. Browse to the unzipped CC3235 Firmware folder and click ‘Launch’.

    If a workspace in CCS is already opened, browse to the unzipped CC3235 Firmware folder in dialog from CCS->File->Switch Workspace->Other, and click ‘Launch’.
