Getting Started with the S32K144 BLDC/PMSM Development Kit

2.1 Download the Development Kit - Application Software

The software package includes projects for most typical hardware configurations.

Note: The installation process asks you to download the latest version of the Automotive Math and Motor Control Library (AMMCLib) Set.

2.2 Get the Integrated Development Environment (IDE)

MCSPTE1AK144 performs better when using S32 Design Studio IDE for Arm^®

Note: Check the S32 Design Studio page for the latest version.

2.3 Get the Run-Time Debugging Tool

MCSPTE1AK144 evaluation board performs better when using the FreeMASTER tool for run-time debugging.

Note: Check the FreeMASTER page for the latest version.

3.1 Set Up Jumpers in S32K144EVB Evaluation Board

3.2 Set Up Jumpers in the DEVKIT-MOTORGD Evaluation Board

3.3 Configure S32K144EVB and DEVKIT-MOTORGD Boards

1. Ensure default S32K144EVB and DEVKIT-MOTORGD jumper options.
2. Ensure jumper J107 in S32K144EVB and DEVKIT-MOTORGD is in position 1-2 for powering board from 12 V power supply.

3. Place DEVKIT-MOTORGD jumpers J9, J10, J11 to position 1-2 for PMSM application or 2-3 for BLDC application, The jumper J8 stays open for 5 V HALL sensors.

4. Make sure the potentiometer for overcurrent comparator is set in position (slightly to the left from the middle) for approximately 8 – 10 A.

3.4 Plug In the Motor

Ensure that the motor phase wires are in the following order, from phase A to phase C:

Note: Phase wires for Linix

Note: Phase wires for Sunrise

3.5 Plug in the Power Supply

Connect the 12 V power supply for the S32K144EVB and DEVKIT-MOTORGD boards, together with the 3-phase PM Motor. S32K144EVB is configured for powering from DEVKIT-MOTORGD board. Keep the DC supply voltage within the range of 8 to 18 V.

Note: The DC power supply voltage affects the maximum motor speed.

3.6 Connect the USB Cable

Connect S32K144EVB to the PC using the USB cable.

Note: Allow the PC to automatically configure the USB drivers if needed.

4.1 Select Application and MCU Programing

Let's take it for a test drive.

Select the appropriate PMSM or BLDC motor control application from the installed directory NXP\MCSPTE1AK144\sw.

Reprogram the MCU using S32 Design Studio:
To import the installed application software project in the S32 Design Studio IDE for Arm^®:

1. Launch S32DS for Arm
2. Go to File → Import, then select General → Existing Projects into Workspace

3. Navigate to the installed application directory: NXP\MC_DevKits\MCSPTE1AK144\sw and choose appropriate project and click O. Then, click Finish

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


4. Use File Explorer to run one of the batch files in your project for loading appropriate files with motor parameters. Do not run batch files from S32DS. The default motor parameters are for Sunrise motor type

   Note: Optionally, you may use one of External Tools configurations in S32DS for loading appropriate files with motor parameters.

   

Optional: These steps should not be necessary since they are automatically executed in the next step.

• Right click on the imported project and select Clean
• Right click on the imported project and select Build

4.2 Debug and Load

In the S32 Design Studio menu click Run → Debug Configuration and select the predefined debug configuration and click on Debug to start loading built code into MCU.

4.3 Let Code Run

To let the code run, click Resume (or press F8), and use Disconnect to avoid interference between the S32DS IDE debugger and the FreeMASTER tool.

4.4 Set Up the Debugging Tool

1. Launch the FreeMASTER application
2. To open the *.pmp FreeMASTER project <selected project>\FreeMASTER_control, click File → Open Project

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

   
3. To enable communication, in the FreeMASTER tool bar, click Go (or press CNTRL+G).
   Successful communication displays in the status bar at the bottom as:
   RS232 UART Communication;COMn;speed = 115200

Application Control

1. To display the application control page, click the App Control tab on the Motor Control Application Tuning Tool menu

2. Configure the motor rpms and turn on the motor drive

When the power supply is connected to the DEVKIT-MOTOGD board, the application is in a READY states - steady green LED on S32K144EVB board. RGB LED also indicates:

• READY, INIT states lighting green LED
• CALIB, ALIGN states - flashing green LED
• RUN state - flashing blue LED
• FAULT state - flashing red LED

Check pending faults

In case of pending faults, click the Clear FAULT on the FreeMASTER MCAT control page, or alternatively press and simultaneously hold SW2 and SW3 on the board.

Start application

To initiate clockwise/counterclockwise spinning of the rotor, click ON/OFF on the control page or press SW2/SW3 on the board.

Set speed

To set the speed, change the speed required variable. Go to the variable watch window by clicking speed gauge, or by pressing the switch SW2/SW3.

Stop application

Stop the application by clicking ON/OFF button on the FreeMASTER MCAT control page or simultaneously press and hold SW2 and SW3 on the S32K144EVB board.
