The FRDM Automotive Board Installation Package bundle allows to enable automatic installation and configuration sw without any interaction. That simplifies the installation procedure.

2.2 Add GCC Toolchain Version 10.2

Latest version of the S32 Design Studio contains GCC toolchain only in version 11.4. For full compatibility with RTD, you need to install GCC also in version 10.2.

In S32 Design Studio, go to Help → S32DS Extensions and Updates from the top menu to open the S32DS Extensions and Updates dialogue where you may install it.

2.3 Download eTPU SW

Download S32K3 ETPU SW RFP 2.0.1.

2.4 Install eTPU SW

In S32DS, go to Help → S32DS Extensions and Updates from the top menu to open the S32DS Extensions and Updates dialogue.

Click Add Update Sites and browse for downloaded eTPU SW updatesite file or use the drag&drop option - drag downloaded updatesite file and drop on S32DS Extensions and Updates menu. Added sw package will also be automatically selected for following installation.

2.5 Get FreeMASTER Application Tool for Real-Time Debugging

Download and install the FreeMASTER application tool for real-time debugging.

Note: for this setup you may even skip the Lite service installation (for which the activation code is required).

2.6 Get Automotive Math and motor Control Library (AMMCLib) Set

Download and install AMMCLib for S32K3xx.

Note: Required is version 1.1.45 or newer.

Note: If possible, install AMMCLib in their default path location for easy later path modification.

2.7 Download the Development Kit Application Software

Download and install the MCSTR2AK396 motor control application software package.

Note: The installation process will also ask you to download the latest version of the Automotive Math and Motor Control Library (AMMCLib) set. The installer will test the minimum required version in the next step.

Let's take your MCSTR2AK396 motor control kit for a test drive.

4.1 Select Application and MCU Programing

Select the appropriate PMSM or BLDC motor control application from the installed directory NXP\MC_DevKits\MCSPTR2AK396\sw .

To import the installed application software project in the S32 Design Studio IDE for S32 Platform:

1. Launch S32DS for S32 Platform
2. Go to File > Import, then select General > Existing Projects into Workspace

3. Navigate to the installed application directory: NXP\MC_DevKits\MCSPTR2AK396\sw and choose appropriate project and click OK. Then, click Finish

Note: Check the box for the option Copy projects into workspace.

Note: MCSPTR2AK396 is a multicore application. Make sure that both projects are selected for import.

4.2 Use Configuration Tool

• Unfold the structure of the M7_0_0 project and double-click on *.mex file to open the project configuration in S32 Configuration Tool

• Ensure that you are configuring the M7_0_0 project, and click Update Code button for generating configuration files. Next, in the S32 Configuration Tool, click the pop down button next to the project name and choose *.mex file for the M7_0_2 project. Click the Update Code accordingly

Note: Always wait until generating configuration files ends. Check the status at the bottom right corner.

4.3 Upload Software and Debug

1. In S32DS, return back to the C/C++ perspective

2. Use the Debug Configuration menu for uploading software into the MCU

3. Next, expand Launch Group and click the first launch configuration. This configuration will upload both the M7_0_0 and M7_0_2 projects to the MCU. Click Debug for building and uploading software into MCU

4. The S32DS will switch into debug perspective where you may let the code run by clicking Resume (or press F8)

5. Click Disconnect to avoid interference between the S32DS IDE debugger and the FreeMASTER tool

4.4 Set Up the Debugging Tool

Launch the FreeMASTER application.

To open the *.pmpx FreeMASTER project \FreeMASTER_control, click File > Open Project.

Note: You can also start it by double clicking directly in the S32DS project folder.

To enable communication, in the FreeMASTER toolbar, click Go (or press Ctrl+G). Successful communication displays in the status bar at the bottom as:

RS-232; port=COMn; speed = 115200

Note: You can check or modify the communication settings by clicking Project → Options.

Application Setup (Optional Step)

If you run MCSPTR2AK396 sw on a modified or own hardware platform, you may need to edit hardware scales and fault triggers. In the Motor Control Application Tuning (MCAT) Tool switch to the Application Setup page and edit values on the left side.

Once you finish, click Save config to generate a static configuration file. You may check file content at the Output file page.

Now, repeat step from the Upload Software and Debug section to build the project and upload the code into MCU.

Note: MCU will go to reset, FreeMASTER reconnecting might be needed (Ctrl+K, Ctrl+G).

Motor Parametrization and Control Loops Autotuning

In a case of motor change, you may benefit from new MCAT 2.0 motor parametrization and control loops autotuning features.

At Motor Parameters page, fill four basic motor parameters that cannot be detected automatically:

• Number of pole pairs
• Nominal Current
• Nominal Speed
• Maximum Speed

Click Update target button and start the motor parameters estimation and automating tuning for control loops. Parameters are automatically updated typically in less than a minute.

For more information about the automatic motor parametrization and control loops autotuning please read AN15061 Application Note in MCSPTR2AK396\doc folder. Default path: c:\NXP\MC_DevKits\MCSPTR2 AK396\doc\ApplicationNotes\AN15061 MCAT 2.0 - Motor Control Application Tuning Tool for PMSM FOC.pdf.

Spin the Motor

Switch, for example, to the Speed Loop page. Under the Speed control tab, configure the required speed and turn on the motor drive.

Select one of the predefined Scopes or Recorders in Project Tree to watch the application variables in real-time. For comfortable run-time debugging you may create or modify any of scopes or recorders.

• Check pending faults

In case of pending faults, click the CLEAR button at MCAT control tab or alternatively press simultaneously SW2 and SW3 on the board.


• Start application

Click On/Off on the control bar or press SW2/SW3 on the board to initiate clockwise/counterclockwise spinning of the rotor.

• Set Speed

Modify Required Speed field on the control bar or change Speed Required in the Variable Watch window. Alternatively control speed by pressing SW2 or SW3 switches.


• Stop Application

Stop the motor by clicking the On/Off button on the MCAT control page, Clear On/Off variable or use the On/Off switch on the 3PHLVPWBRDPCIE board.

Note: For more information about MCAT tool please read AN15061 Application Note in the MCSPTR2AK396\doc folder. Default path: c:\NXP\MC_DevKits\MCSPTR2AK396\doc\ApplicationNotes\AN15061 MCAT2.0 - Motor Control Application Tuning Tool for PMSM FOC.pdf
