NXP S32K1xx MATLAB & Simulink Developer Environment Setup

The following documentation details how to set up MATLAB and Simulink for NXP S32K1xx embedded development.

1 Initial Software Installs / Setup

1.1 MATLAB* and Add-ons*

MATLAB + Add-ons* only for Windows.

• Some MATLAB packages are only supported for Windows:
  1. Simulink.
  2. Embedded Coder.
  3. Simulink Coder.
  4. Stateflow.
  5. NXP Support Package S32K1xx.

2 Step-by-Step Setup

2.1 Opening NXP Support Package S32K1xx

2.1.1 Finding the Add-on

Open up MATLAB Add-Ons → Add-On Manager.

• Right-click on the previously installed NXP Support Package S32K1xx and select Open Folder.

2.1.2 Running the MATLAB Script

Run the NXP_Support_Package_S32K1xx.m file.

• If you're new to MATLAB, it's under EDITOR → Run.

2.1.3 Script GUI

The Support Package window should open.

• After completing each sub-step, the clickable buttons should turn green.
• The web page for both download Files and License Keys pages (NXP Model-Based Design Toolbox for S32Kxx Automotive Microprocessors Family) should look something like this:

2.2 S32Kxx Model-Based Design (MBT) Toolbox Install

2.2.1 Download

Download the newest version of the MBT Toolbox.

• As of writing (2024-01-28), the window for setting up version 4.3.0:

Use the recommend link options below (in order of highest to least recommended):

You can use the newly opened window, but it and NXP's website is super buggy!

2.2.2 Install

Go back to the NXP Support Package S32K1xx GUI and click the Install MLTBX File as Add-On button, direct to the installed / extracted .mltbx file.

2.2.3 Verify Install

You should now see NXP_MBDToolbox_S32K1xx on your Add-On manager.

2.3 S32Kxx Model-Based Design (MBT) Toolbox License

2.3.1 Obtain Host ID

You will be promoted for a Host ID later on. The Host ID is either a Volume Serial Number or a MAC address that restricts your license to 1 computer.

• Note: The license is removable / reversible.

To get your Host ID follow the terminal commands bellow:

2.3.1.1 Windows

Host ID is either the Volume Serial Number of MAC address.

vol c:

getmac -v

2.3.1.2 macOS

Host ID is the MAC address of the en0 device.

ifconfig en0 | grep ether

2.3.1.3 Linux

Host ID is the MAC address any interface. If interfaces are enumerated, use the lowest-enumerated interface.

/sbin/ifconfig <interfaceName>

2.3.2 Generate License File

Go to NXP Software Portal for Downloads and Licenses.

Use the recommend link options below (in order of highest to least recommended):

2.3.3 Download License File

The license file might auto download (does not most of the time).

Copy the contents of the license key generated and save it to a file called license.dat.

• If you're on windows create a license.txt file with Notepad. Paste the file contents, save the file, close, and then rename the file license.dat.

The final result should be a .dat file with the license key information.

2.3.4 Activate License File

Go back to the NXP Support Package S32K1xx GUI and click the Activate NXP MBD Toolbox button, direct to the license .dat file.

2.4 Verify Complete Setup

Verify the setup on the NXP Support Package S32K1xx GUI. All "verify" sub-step buttons should now be Green.

• Note: Convert ZIP to MLTBX may not be required depending on the download process.

3 Step-by-Step Initial setup

1. Open up MATLAB and Simulink.
2. Open up the NXP Model-Based Design Toolbox for S32K1xx MCUs tool box tab.
3. Open the Embedded Coder app.
4. Build your model, in this example the "GPIO on S32K144 LED & Button" block is used.
5. Generate Code or Build (generate and flash) to generate code and/or flash the generated code to a connected MCU.
