Run a demo using MCUXpresso IDE

Note: Ensure that the MCUXpresso IDE toolchain is included when generating the MCUXpresso SDK Package.

This section describes the steps required to configure MCUXpresso IDE v11.1.1 to build, run, and debug example applications. The hello_world demo application targeted for the FRDM-K32L2B hardware platform is used as an example, though these steps can be applied to any example application in the MCUXpresso SDK.

Select the workspace location

Every time MCUXpresso IDE launches, it prompts the user to select a workspace location. MCUXpresso IDE is built on top of Eclipse which uses workspace to store information about its current configuration, and in some use cases, source files for the projects are in the workspace. The location of the workspace can be anywhere, but it is recommended that the workspace be located outside of the MCUXpresso SDK tree.

Build an example application

To build an example application, follow these steps.

1. Drag and drop the SDK zip file into the Installed SDKs view to install an SDK. In the window that appears, click OK and wait until the import has finished.

   

2. On the Quickstart Panel, click Import SDK example(s)….

   

3. In the window that appears, expand the K32L2Bx folder and select K32L2B31xxxA. Then, select frdmk32l2b and click Next.

   

4. Expand the demo_apps folder and select hello_world. Then, click Next.

   

5. Ensure the option of Redlib: Use floating point version of printf is selected if the cases’ print floating point numbers are on the terminal for demo applications such as adc_basic, adc_burst, adc_dma, and adc_interrupt. Otherwise, it is not necessary to select this option. Then, click Finish.

Run an example application

For more information on debug probe support in the MCUXpresso IDE 11.1.1, visit community.nxp.com.

To download and run the application, perform these steps:

1. See default_debug_interfaces.md# to determine the debug interface that comes loaded on your specific hardware platform. For LPCXpresso boards, install the DFU jumper for the debug probe, then connect the debug probe USB connector.

   • 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 with 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.

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

4. On the Quickstart Panel, click on Debug ‘frdmk32l2b_demo_apps_hello_world’ [Debug].

   

5. The first time you debug a project, the Debug Emulator Selection Dialog is displayed, showing all supported probes that are attached to your computer. Select the probe through which you want to debug and click the OK button. (For any future debug sessions, the stored probe selection is automatically used, unless the probe cannot be found.)

   

6. The application is downloaded to the target and automatically runs to main():

   

7. Start the application by clicking the Resume button.

   

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