Run an example application

To download and run the application, perform these steps:

  1. See the table in Default debug interfaces to determine the debug interface that comes loaded on your specific hardware platform.

    • For boards with the CMSIS-DAP/mbed/DAPLink interface, visit mbed 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 that LPC board drivers are installed.

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

    • If using J-Link either a standalone debug pod or OpenSDA, install the J-Link software (drivers and utilities) from www.segger.com/jlink-software.html.

    • For boards with the OSJTAG interface, install the driver from www.keil.com/download/docs/408.

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

    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 |

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

    |

|

  1. 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.

    |

|

  1. 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.
