2.3 Getting Started with the MCUXpresso SDK
The MCUXpresso Software Development Kit (SDK) is complimentary and includes full source code under a permissive open-source license for all hardware abstraction and peripheral driver software.
Click below to download a pre-configured SDK release for the LPCXpresso54608, which includes versions for MCUXpresso IDE, Keil MDK and IAR EWARM. Use LPCXpresso54608 as the target board; LPCXpresso54628 will have a specific SDK package from November 2017, but is binary compatible with LPCXpresso54608.
You can also use the online MCUXpresso web tool to create a custom SDK package for the LPCXpresso54628 using the SDK builder.
2.4 Install your toolchain
NXP offers a free, GNU/Eclipse based toolchain called MCUXpresso IDE.
Want to use a different toolchain?
No problem, The MCUXpresso SDK includes support for other tools such as IAR and Keil.
To set up your LPCXpresso54628 for use with 3rd party tools, first install LPCScrypt in order to install the board’s device drivers. The video below shows how to use LPCScrypt to program your board’s debug probe using this utility.
The video on this Getting Started section are for LPCXpresso54608, but the steps are the same for LPCXpresso54628.
2.5 MCUXpresso Config Tools
The MCUXpresso Config Tool is an integrated suite of configuration tools that guides users in creating new MCUXpresso SDK projects, and provides pin and clock tools to generate initialization C code for custom board support.
To learn more about the basic interactions between the tools while working with either an imported MCUXpresso SDK example project or creating a new project within the IDE, watch this three-part video series Basic Application Development Using MCUXpresso IDE and MCUXpresso Config Tools.
2.6 Serial terminal
Most of the MCUXpresso SDK examples set up for IAR and Keil tools use the MCU UART for printf output, and this is also an option for the MCUXpresso IDE. If you are not sure how to use a terminal application try one of these tutorials:
Not sure how to use a terminal application? Try one of these tutorials:
Tera Term Tutorial
Tera Term is a very popular open source terminal emulation application. This program can be used to display information sent from your NXP development platform's virtual serial port.

3.2 Build, Run and Debug MCUXpresso SDK Examples
If one or more of the demo applications or driver examples sounds interesting, you're probably wanting to know how you can build and debug yourself. The Getting Started with SDK v.2.0 for LPC546xx guide provides easy, step-by-step instructions on how to configure, build, and debug demos for all toolchains supported by the SDK.
Use the guide below to learn how to open, build and debug an example application using the MCUXpresso IDE.
3.3 To run the LPCXpresso54628 board at over 180MHz
To run the LPCXpresso54628 board at over 180MHz, a modified version of the device power library found in the MCUXpresso SDK (for LPCXpresso54608) and appropriate clock configurations need to be used. A package, including a Technical Note, power library and example code to show how to do this is provided under the Software and Tools tab for this board.
Building and debugging with MCUXpresso IDE
The video on this Getting Started section are for LPCXpresso54608, but the steps are the same for LPCXpresso54628.
Using a different toolchain?
Running a demo using IAR
Build an Example Application
The following steps will guide you through opening the led_output application. These steps may change slightly for other example applications as some of these applications may have additional layers of folders in their path.
-
If not already done, open the desired example application workspace. Most example application workspace files can be located using the following path:
boards/sdk_board_name/example_type/application_name/iarUsing the hello_world demo as an example, the path is:
/boards/LPCXpresso54628/driver_examples/gpio/led_output/iar -
Select the desired build target from the drop-down. For this example, select the "hello_world – Debug" target.
-
To build the application, click the “Make” button, highlighted in red below.
-
The build will complete without errors.:

-
Open the MDK IDE, which is called µVision. In the IDE, select the "Pack Installer" icon.
-
In the Pack Installer window, navigate to the section with the LPC packs (they are in alphabetical order). The Kinetis packs start with "Keil::LPC" and are followed by the MCU family name, for example "Keil::LPC54000". Because this example uses the LPCXpresso54628 platform, the LPC54000 family pack is selected. Click on the "Install" button next to the pack. This process requires an internet connection to successfully complete.
-
After the installation finishes, close the Pack Installer window and return to the µVision IDE.
Build the Example Application
The following steps will guide you through opening the gpio_led_output application. These steps may change slightly for other example applications as some of these applications may have additional layers of folders in their path.
-
If not already done, open the desired demo application workspace in:
boards/sdk_board_name/example_type/application_name/mdkThe workspace file is named
.uvmpw, so for this specific example, the actual path is:boards/LPCXpresso54628/driver_examples/gpio/led_output/mdk/gpio_led_output.uvmpw -
To build the demo project, select the "Rebuild" button, highlighted in red.
-
The build will complete without errors.
