Run a demo application using IAR

This section describes the steps required to build, run, and debug example applications provided in the MCUXpresso SDK.

Note: IAR Embedded Workbench for Arm version 8.40.2 is used as an example to show below steps, and the IAR toolchain should correspond to the latest supported version, as described in the MCUXpresso SDK Release Notes for FRDM-K32L2A4S (document MCUXSDKK32L2A4SRN).

Build an example application

Perform the following steps to build the hello_world example application.

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

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

    Using the FRDM-K32L2A4S hardware platform as an example, the hello_world workspace is located in:

    <install_dir>/boards/frdmk32l2a4s/demo_apps/hello_world/iar/hello_world.eww

  2. Select the desired build target from the drop-down menu. For this example, select the hello_world – debug target.

  3. To build the demo application, click the Make button highlighted in red below.

  4. The build completes without errors.

Run an example application

To download and run the application, perform these steps:

  1. See the table in default_debug_interfaces.md# to determine the debug interface that comes loaded on your specific hardware platform.

    • For boards with CMSIS-DAP/mbed/DAPLink interfaces, visit developer.mbed.org/handbook/Windows-serial-configuration and follow the instructions to install the Windows® operating system serial driver. If running on Linux® OS, this step is not required.

    • The user should install LPCScrypt or MCUXpresso IDE to ensure LPC board drivers are installed.

    • For boards with P&E Micro interfaces, visit www.pemicro.com/support/downloads_find.cfm and download the P&E Micro Hardware Interface Drivers package.

  2. Connect the development platform to your PC via USB cable.

  3. Open the terminal application on the PC, such as PuTTY or TeraTerm, and connect to the debug COM port (to determine the COM port number, see How to determine COM port). Configure the terminal with these settings:

    1. 115200 or 9600 baud rate, depending on your board (reference BOARD_DEBUG_UART_BAUDRATE variable in the board.h file)

    2. No parity

    3. 8 data bits

    4. 1 stop bit

  4. In IAR, click the Download and Debug button to download the application to the target.

  5. The application is then downloaded to the target and automatically runs to the main() function.

  6. Run the code by clicking the Go button.

  7. The hello_world application is now running and a banner is displayed on the terminal. If it does not appear, check your terminal settings and connections.
