Getting Started with the DEVKIT-MPC5748G

2.1 Download Software Examples

Download

2.2 Get the Integrated Development Environment (IDE)

S32K144EVB performs better when using S32 Design Studio for Power Architecture^®.

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

Download

• The installation will requires Microsoft Visual C++ 2013 package. If libraries are already installed, a Modify Setup dialog box appears with the requirement Repair.
• When asked for Activation ID, copy and pate it from the Download page and select an online activation.
• During the Installation, it may ask you to install P&E device drivers.

2.3 Get the PC Configuration Driver

Some example applications output data over the MCU UART, so make sure that the driver for the board's virtual COM port is installed.

Note: Make sure the board is plugged into your PC before you run the driver installer.

Download Config Driver

To view the serial output from the MCU’s UART, run your preferred terminal application once the serial port driver is installed. Configure the terminal to 57,600 baud rate, 8 data bits, no parity and 1 stop bit.

Note: To determine the port number of the DEVKIT-MPC5748G's virtual COM port, open the device manager and look under the "Ports" group.

3.1 Download Software Examples

Watch the video to set up your evaluation board. You can also use the step-by-step guide.

3.2 Set Up Jumpers in the Evaluation Board

The J11 is the only jumper. It helps select the power source:

• 1-2: Default external 12 V supply
• 2-3: USB powered 5 V supply, through OpenSDA interface

Note: For high power/current-consuming applications (like using external shield boards) use “External 12 V Supply” only.

Learn more about OpenSDA at Projects and Tutorials section.

3.3 Plug the USB Cable

Connect one end of the USB cable to the PC and the other end to the micro-B connector on the DEVKIT-MPC5748G board. Allow the PC to automatically configure the USB drivers.

The pre-loaded example project utilizes the DEVKIT-MPC5748G user push button (SW2) and the user LEDs. Once the board is plugged in, LEDs will blink in default pattern. Press push button to switch between the two different patterns. Use Potentiometer to change blinking speed.

Note: Clock is configured to PLL running @ 160 MHz.

Let’s take it for a test drive.

4.3 Debug a Project in IDE

1. Connect a debugger to both the board and the PC.
   

   Note: For DEVKIT-MPC5748G, OpenSDA works as a debug adapter, so no standalone debugger is required.

2. Open Debug Configuration options in the top menu.

3. Select a project and interface and then click Debug.
   (Example: “FirstProject_Z4_0_Debug” and “OpenSDA for DEVKIT-MPC5748G”)
   

   Note: The port is the comport where device is connected.

4.4 Debug a Project from RAM

To configure a project to debug from RAM, follow one of these paths:

1. Go to Project > Build Configurations > Set Active > Debug_RAM.
2. To select Debug_RAM, click the arrow near the hammer icon.

Note: Repeat for all related projects and follow the steps in 4.2 Build a New Project in IDE.

Finally, to debug from RAM, select the RAM-related session while debugging.

Note: Follow the steps in 4.3 Debug a Project in IDE.

4.5 Make Projects From Built-In Examples

1. Launch S32 Design Studio for Power Architecture, From Example, go to File > New > New S32DS Project.

2. Select the built-in project of your choice and click Finish.

3. The selected project will be copied to the active workspace.


4. The DEVKIT-MPC5748G example codes also include the projects from AN4830: Qorivva Recipes for MPC574xG

   Go to Setup > Serial Port and update the settings.
4. Verify that the connection is open.
   Once connected, Tera Term will update its title bar:

You are ready to go.

PuTTY 101

PuTTY is a popular terminal emulation application. This program can be used to display information sent from your NXP development platform's virtual serial port.

1. Download PuTTY and run the installer

   Download Putty from Chiark
2. Launch PuTTY

3. Configure the serial radio button and enter the COM port number you determined earlier. Also enter the baud rate.

   Note: A baud rate of 57600 is recommended.



4. Open the serial connection.

   Note: The terminal window will open if your board is already plugged in.

   PuTTY will alert you if the configuration is not correct.

You are ready to go.

Using the Virtual Serial Port

1. Determine the symbolic name assigned to the EVB-S32K144 virtual serial port.
   In Windows, open Device Manager and look for the COM port named OpenSDA-CDC Serial Port.

2. Open the serial terminal emulation program of your choice.

   Note: For Windows you can use Tera Term, PuTTY or HyperTerminal.

3. Program one of the “code examples” using S32 Design Studio IDE.
4. Configure the terminal emulation program. Most embedded examples use 8 data bits, no parity bits and one stop bit (8-N-1). Match the baud rate to the selected serial test application and open the port.
5. Press and release Reset (SW1) at any time to restart the example application. Resetting the embedded application will not affect the connection of the virtual serial port to the terminal program.

Note: Refer to the OpenSDA User’s Guide for a description of a known Windows issue when disconnecting a virtual serial port while the COM port is in use.
