This is the documentation for the latest (main) development branch of mcuxpresso sdk. If you are looking for the documentation of previous releases, use the drop-down menu on the left and select the desired version.

Run an example application

To download and run the application, perform these steps:

  1. Determine the debug interface that comes loaded on your specific hardware platform.

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

    • If using J-Link either a standalone debug pod or MCU-LINK, install the J-Link software (drivers and utilities) from Segger.

  2. Connect the development platform to your PC via USB cable using MCU-LINK USB connector.

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

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

    • No parity

    • 8 data bits

    • 1 stop bit

  4. In μVision, after the application is built, click the Download button to download the application to the target.

  5. After clicking the Download button, the application downloads to the target and is running. To debug the application, click the Start/Stop Debug Session button, highlighted in red in Figure 3.

  6. Run the code by clicking the Run button to start the application.

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