Getting Started with the S32K144EVB

2.1 Integrated Development Environment (IDE)

S32K144EVB performs better when using S32 Design Studio for Arm v1.3.

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

2.2 Run-Time Debugging Tool

S32K144EVB evaluation board performs better when using the FreeMASTER tool for run-time debugging. You can also download and install the FreeMASTER Communication Driver (source code already included in the example project).

Note: Check the FreeMASTER page for the latest version.

3.1 Set Up Jumpers in S32K144EVB Evaluation Board

Watch the video or use the step-by-step guide, below.

3.2 Plug In the 12 V Power Supply

The S32K144EVB evaluation board powers from a USB or external 12 V power supply. By default USB power is enabled with J107 jumper (2-3 closed).

Connect the USB cable to a PC using a USB cable and connect other end of USB cable (microUSB) to mini-B port on to J7 on your S32K144EVB.

Allow the PC to automatically configure the USB drivers if needed. Debug is done using OpenSDA through J7.

Note: When powered through USB, LEDs D2 and D3 should light green.

Once the board is recognized, it should appear as a mass storage device in your PC with the name EVB-S32K144.

The S32K144EVB evaluation board is preloaded with a software in which red, blue and green LEDS will toggle at different rates:

S32K144EVB_GS-3.2b-LED-TOGGLE

Let’s take it for a test drive.

4.1 Communicate with Run-Time Debugger

Figure 2. Configure the communication port through OpenSDA with a 115200 b/s speed rate

• Manually = Project → Options → Comm

  

• Automatically = Tools → Connection Wizard

4.3 Import and Debug the Project to IDE

Watch the video to create a new project and load a code example to blink an LDE. The video also covers hoe to build and debug your project. You can also use the step-by-step guide.

Launch the S32 Design Studio for Arm and select a default Workspace or specify a new one, then click OK.

Note: Uncheck the box Use this as default and do not ask again.

To create a new project, select File → New → Project

Choose a project name and then select a project type, then click Next.

Note: You can select the project type in the executable or library folder.

Select Debugger and Library, then click Finish.

4.4 Set Up Debug Configuration

Select OpenSDA to debug with it.

Select your project, and click on Debug Configuration.

Select the debug configuration under GDB PEMicro Interface Debugging, click the Debugger tab.

In Interface, select OpenSDA. If your board is plugged in, it should appear in Port. To finish, click Apply then Debug.

5.8 Debug with FreeMASTER

Debug configuration is only required once. Subsequent starting of debugger does not require those steps.

There are three options to start debugging:

• If the Debug Configuration is still open, click Debug on the bottom right.
• Select Run → Debug (or hit F11)

  Note: This method currently selects the desktop target (project.elf) and gives an error. Do not use until this is changed.

  
• Select the bug icon and select …_debug.elf target

  Note: This is the recommended option.

5.9 Optional - P&E Debug Configuration

1. Select Debug Configurations:

2. Create a new P&E launch configuration:

   Click to create a new P&E launch and then click Debugger.

   
3. Select a S32K144 device and then click Apply and debug your application.

OpenSDA

OpenSDA is an open-standard serial and debug adapter. It bridges serial and debug communications between a USB host and an embedded target processor. OpenSDA software includes a flash-resident USB mass-storage device (MSD) bootloader and a collection of OpenSDA applications.

The S32K144EVB comes with the MSD Flash Programmer OpenSDA Application preinstalled.

Follow these instructions to run the OpenSDA Bootloader and update or change the installed OpenSDA Application.

The MSD Flash Programmer is a composite USB application that provides a virtual serial port and an easy and convenient way to program applications into the KEA MCU. It emulates a FAT16 file system, appearing as a removable drive in the host file system with a volume label of EVB-S32K144. Raw binary and Motorola S-record files that are copied to the drive are programmed directly into the flash of the KEA and executed automatically. The virtual serial port enumerates as a standard serial port device that can be opened with standard serial terminal applications.
