Run a demo using Keil MDK/μVision

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

Install CMSIS device pack

After the MDK tools are installed, Cortex Microcontroller Software Interface Standard (CMSIS) device packs must be installed to fully support the device from a debug perspective. These packs include things such as memory map information, register definitions, and flash programming algorithms. Follow these steps to install the RW612 CMSIS pack.

  1. Download the RW612 pack.

  2. After downloading the DFP, double click to install it.

Build an example application

  1. Open the desired example application workspace in:

    <install_dir>/boards/<board_name>/*<example\_type\>*/<application_name>/mdk

    The workspace file is named as <demo_name>.uvmpw. For this specific example, the actual path is:

    <install_dir>/boards/rdrw612bga/demo_apps/hello_world/mdk/hello_world.uvmpw

  2. To build the demo project, select Rebuild, highlighted in red.

  1. The build completes without errors.

Run an example application

To download and run the application, perform these steps:

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

  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 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. To debug the application, click load (or press the F8 key). Then, click the Start/Stop Debug Session button.

    Note: Make sure that the board is set to FlexSPI flash boot mode (U38 all off) before using Keil debug.

  1. Run the code by clicking Run to start the application.

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