S32K144EVB performs better when using S32 Design Studio for Arm v1.3.
Note: Check the S32 Design Studio page for the latest version.
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.

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
Note: When powered through USB, LEDs
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:
Let’s take it for a test drive.
1. Launch the FreeMASTER application:
2. Configure the communication port through OpenSDA with a 115200 b/s speed rate:
Manually = Project > Options > Comm
Automatically = Tools > Connection Wizard
The FreeMASTER JumpStart project will be automatically downloaded from NXP Semiconductors once the FreeMASTER application detects the web address stored as an TSA active content in the flash.

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.
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.

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.
|Enter OpenSDA Bootloader Mode||Load an OpenSDA Application|
A removable drive should now be visible in the host file system with a volume label of BOOTLOADER. You are now in OpenSDA Bootloader mode.
Note: Follow the “Load an OpenSDA Application” instructions to update the MSD Flash Programmer on your S32K144EVB to the latest version.
You are now running the latest version of the MSD Flash Programmer. Use this same procedure to load other OpenSDA Applications.
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.
|Using the MSD Flash Programmer||Using the Virtual Serial Port|
The new application should now be running on the S32K144EVB. Starting with v1.03 of the MSD Flash Programmer, you can program repeatedly without the need to unplug and reattach the USB cable before reprogramming.
