3.3.5.4.2 Building and Loading the Project and Setting up Debug Environment
  1. Right-click on the project name and click Rebuild Project.
  2. The project builds successfully.
  3. In the Project Explorer, make sure the correct target configuration file is set as Active under targetConfigs.
  4. Then, click Run → Debug to launch a debugging session.
  5. The project then loads on the device and the CCS debug view becomes active. The code halts at the start of the main routine.
  6. To add the variables in the watch/expressions window, click View → Scripting Console to open the scripting console dialog box. On the upper right corner of this console, click on open and then browse to the setupdebugenv_chX.js script file located inside the project folder. This populates the watch window with the appropriate variables needed to debug the system.
  7. Click on the Continuous Refresh button TIDA-010086 on the watch window to enable continuous update of values from the controller.
