Running a Demo using IAR Embedded Workbench

[#1]

The following steps will guide you through opening the hello_world application. The instructions for compiling and debugging the Cortex M33 core are covered in the instructions below.

Build an Example Application

Please use IAR Embedded Workbench for Arm version 9.50.1 or above.

1. First, unzip the previously downloaded FRDM-MCXW71 SDK package

2. Open the desired example application workspace. Most example application workspace files can be located using the following path:

   <install_dir>/boards/<sdk_board_name>/<example_type>/<application_name>/iar

3. Select the desired build target from the drop-down. For this example, select the "hello_world - debug" target
   
4. Open the project properties by doing a right-click on the project and selecting "Options"
   
5. Now, go to the "Debugger" section and change the debugger driver to CMSIS DAP. Press the OK button
   
6. To build the application, click the "Make" button, highlighted in red below
7. The build will complete without errors
   Note: In case of building errors, make sure that the correct board is selected, right-click in Project → Options → General Options → Target → Device. Select the NXP MCU you are using and is supported by the IAR version you have installed.

Run an Example Application

1. Connect the development platform to your PC via USB cable to 'MCU-Link' port
   
2. Click the "Download and Debug" button to download the application to the target
   
3. The application is then downloaded to the target and automatically runs to the main() function
4. Run the code by clicking the "Go" button to start the application
   
5. The hello_world application is now running on the MCU.
