2. Get Software
2.1 Integrated Development Environment (IDE)
The S32 Design Studio for Arm® is a complimentary Integrated Development Environment (IDE) for automotive and ultra-reliable Arm-based microcontrollers that enables editing, compiling and debugging of designs.
DOWNLOAD S32DS FOR ARM2.2 Run-Time Debugging Tool
S32K146EVB-Q144 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).

The S32K146EVB-Q144 evaluation board powers from a USB or external 12 V power supply. By default USB power is enabled with
J107 - Connect USB cable to a PC
- Allow the PC to automatically configure the USB drivers if needed
- Debug is done using OpenSDA through
J7 - When powered through USB, LEDs
D2andD3should light green - Once the board is recognized, it should appear as a mass storage device in your PC with the name S32K146EVB-Q144
- Board is preloaded with a software, in which the red, blue and green LEDs will toggle at different rates
4. Build, Run
4.1 Flash the Out-of-Box Demo
Download the S32K146EVB_OOBE_FreeMASTER_Firmware.srec from Software and Tools tab . Then drag and drop the downloaded image file into your S32K146EVB-Q144 disk that is listed in your PC window.
4.2 Communicate with Run-Time Debugger
Open the FreeMASTER application on your PC. You should see Welcome page:
Setup communication port to “opensda” and speed to 115200 b/s:
-
Setup communication manualy:
“Project > Options > Comm"
-
Setup communication automatically:
“Tools > Connection Wizard”
4.3 FreeMASTER JumpStart Project Download
Once the FreeMASTER application detects the web address stored as an TSA active content in the flash memory of the S32K146EVB-Q144 MCU, the download of the FreeMASTER project from NXP Semiconductors will be initiated.
4.4 FreeMASTER JumpStart Project Loaded
The FreeMASTER JumpStart project description:
4.5 FreeMASTER JumpStart
Display main project panel,
“Project > View > Project Tree“..
Display real-time oscilloscope graph examples such as
“Potentiometer“ or “Touch Sense Electrodes“.
4.6 Create a New Project in S32 Design Studio
To create a new project for first time at Eclipse Launcher, please follow the following steps:
- Start program: Click on “S32 Design Studio for Arm” icon
- Select workspace:
- Choose default (see below example) or specify new one
- Suggestion: Uncheck the box “Use this as the default and do not ask again”
- Click OK
- Select “File > New > S32DS Application Project”
-
Project Name:
- Example: “FirstProject”
-
Project Type:
- Select from inside executable or library folder
- Click on “Next”

Introduction to 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 Firmware Apps. S32K146EVB-Q144 EVB 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 running the latest version of the MSD flash programmer. Use this same procedure to load other Firmware Apps. |
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 S32K146 MCU. It emulates a FAT16 file system, appearing as a removable drive in the host file system with a volume label of S32K146EVB-Q144.
Raw binary and Motorola S-record files that are copied to the drive are programmed directly into the flash of the S32K146 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 S32K146 EVB. 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. Drag one of the |
