1.2 Get to Know the MPC5775E-EVB Control Board

MPC5775E-EVB is powered from 3-phase low-voltage power stage. In standalone operation MPC5775E-EVB requires 12 V external DC power supply. It includes a MC33FS6520LAE system basis chip (SBC) for the board power supply. Also features a debug selectable between external debug connection via JTAG or on-board OpenSDA(USB interface), headers available for eMIOS, ADCs, DSPI, eTPU and motor control connector (PCIe X4 style edge connector) modules.

MPC5775E-EVB control board communication features:

  • SBC CAN physical interface (selectable J48/J50 between FlexCAND /MCAN1 [GPIO246 and GPIO247] or FLEXCANC [GPIO87 and GPIO88])
  • Option to select CAN termination J49
  • SBC LIN physical interface connected to RXDC/TXDC (J51/J54 connected by default)
  • Leader or follower mode supported (J52 VSUP connection)
  • TJA1145T/FD CAN physical interface (selectable between FlexCANA /MCAN0 GPIO83 and GPIO84] and FlexCANB [GPIO85 and GPIO86])
  • TJA1100 automotive Ethernet PHY (physical interface)

Note: The SBC_FS0B LED (fault output) is lighting because the PowerSBC chip is in debug mode for possibility to debug the application.

1.3 Get to Know the 3-phase Low Voltage Power Stage Board

3-phase low-voltage power stage board features a SMARTMOS® MC33937A intelligent mos-fet gate driver with 12 - 24 VDC input power supply voltage range, reverse polarity protection, resolver excitation generator and resolver feedback signals processing, encoder and Hall sensor, and a phase current and DC bus current measurement by shunt resistors, DC-bus overvoltage, overcurrent and undervoltage fault detection.

It also has a breaking resistor, DC/DC power supply for gate driver and auxiliary circuits and control buttons, plus galvanically isolated SPI (not populated), OC/OV protection and a power plug PWM 3-phase outputs.

4. Build, Run

Let's take your MCSPTR2A5775E development kit for a test drive.

4.1 Import the Project to IDE

Import the installed application software project in the S32 Design Studio for power architecture. Launch S32DS and then click File > Import and then select General > Existing Projects into Workspace.

Navigate to the installed application directory: MC_DevKits\MCSPTR2A5775E\sw\ and click OK, then Finish.

Note: Check also an option for copy selected project into your workspace.

4.2 Build the Project – OPTIONAL

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

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

4.3 Debug for Loading Code Into MCU

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.

4.4 Let Code Run and Disconnect

Let code run by clicking on the Resume (F8) button, and use Disconnect button for avoiding interference between S32DS debugger and FreeMASTER tool.

4.5 Debug Your Motor Control Application Using a Debugger Tool

Start the FreeMASTER project for debugging by launching FreeMASTER and then open *.pmp file from the folder <selected project>\FreeMASTER_control by clicking File > Open Project...

Note: You may start it by double click directly from S32DS project explorer.

4.6 Start a Connection With the MPC5775E MCU

Click the green GO button in the FreeMASTER toolbar or press <CTRL +G> to enable the communication.

Successful communication is signalized in the status bar at very bottom as: RS232 UART Communication;COMn; speed = 115200

Note: The connection parameters are already predefined in FreeMASTER project. You may change them in project options or using the Connection Wizard.

4.7 Control Your Motor

Click App Control tab in the motor control application turning (MCAT) tool menu to display the application control page. Configure the motor rpms and turn on the motor drive.

Success, motor runs.

Start Your Application

  1. Connect the micro USB cable to J116 (bottom side) if not already connected.

    If necessary, install the driver to make the COM port available as an OpenSDA port, which can be checked under COM and LPT ports in the device manager.

    Note: You will be able to see the OpenSDA - CDC Serial Port if the driver is available.

  2. Go to the device manager and right click the COM port detected and select Update Driver Software.

    Select Browse My Computer for driver software and select the OpenSDA driver that has been downloaded.

    Restart your machine.

  3. Connect power supply 24 V to the inverter and micro USB cable to micro USB port on the development board.

    Turn on the power switch.

    Note: Make sure the status LEDs for voltage levels 3.3 V (D14), 5 V (D15), 1.25 V (D16) and 12 V (D32) supply are lighting green on the controller board.

  4. Open Tera Term on Windows PC and select the serial port to which the micro USB of the development board is connected and click OK

    Go to Setup > Serial Port and select 19200 as the baud rate.

  5. After resetting the board by pressing the reset button (SW1)

    You will be able to see this welcome message on the terminal:

  6. Run the Device Manager on your system.

    Check which COM port was assigned to the OpenSDA – CDC Serial Port.

  7. The power stage cannot be powered without the controller board when Brake Resistor (J2) is populated.

    The absence of the controller board leads to a high BRAKE_GATE signal, and a large current flows through the BRAKE_RESISTOR, creating a considerable burn hazard as the resistor will dissipate enough heat to harm on contact. If PWM braking is used, software must explicitly control the BRAKE_GATE signal. Thus, the power stage board must always be connected to the controller board.

    1. Connect the micro USB cable to the MCSPTR2A5775E controller board and the host PC.
    2. Connect the controller board to the power stage using PCIe connector J1.
    3. Connect the 24 V power supply to the power stage. The controller board power supply is taken from the power stage.

    Note: Make sure to perform these steps in correct order.

  8. Start the FreeMASTER project MCSPTR2A5775E.pmp located in MCSPTR2A5775E_Z7_0\ FreeMASTER_control project directory.

    Click on Project\Options menu, choose the RS232 COM port number that was assigned to the virtual COM port driver and set the communication speed to 115200 Bd.

    Enable communication by pressing the START button in FreeMASTER or by pressing <CTRL+K>.

  9. Start the application by pressing 1 - “RUN” on the flip/flop (ON/OFF) switch on the FreeMASTER control page, or by positioning the RUN/STOP switch (SW1 on the power stage board) to the RUN position (transition from STOP to RUN in case the switch was in the RUN state when a fault event occurred).

  10. Stop the application by pressing 0 - “STOP” on the flip/flop (ON/OFF) switch on the FreeMASTER control page, or by positioning the RUN/STOP switch (SW1 on the power stage board) to the STOP position.

    11. Note: You can RESET the application anytime by pressing the SW1 on the MCSPTR2A5775E controller board.
