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.

2.2 Run-Time Debugging Tool

S32K146EVB 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.

Plug It In

3.1 Power up the Board

  • The S32K146-EVB evaluation board powers from a USB or external 12V power supply. By default USB power is enabled with J107
  • Connect the USB cable to a PC using supplied USB cable
  • Connect other end of USB cable (microUSB) to mini-B port on S32K146 at J7
S32K146 Board USB Connect
  • Allow the PC to automatically configure the USB drivers if needed.
  • Debug is done using OpenSDA through J7
  • 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 S32K146EVB
S32K146 Devices and Drivers
  • Board is preloaded with a software, in which the red, blue and green LEDs will toggle at different rates

4.2 Communicate with Run-Time Debugger

Open the FreeMASTER application on your PC. You should see Welcome page:

S32K146 FREEMASTER WELCOME

Setup communication port to “opensda” and speed to 115200 b/s:

  • Setup communication manualy:
    “Project > Options > Comm"
S32K146 BOARD OPENSDA
  • Setup communication automatically:
    “Tools > Connection Wizard”

4.8 Create an Example from SDK

The S32 Design Studio IDE already includes the Software Development Kit for quickly develop applications on S32K1xx devices.

  • To create a project using an example go to “File > New > S32DS Project from Example”
S32K146 SDK
  • Go to the “S32K1xx SDK RTM v4.0.1” Example Projects section and select the example that wants to be used
  • In this example the “hello_world” is selected
S32K146 SDK HELLOWORLD
  • A new project would be created in the workspace
  • Click on “generate code icon” and then on “Debug”, as indicated
S32K146 SDK CODEICON
  • If run correctly, the LED should start blinking red and green

The complete documentation of the SDK can be found in:
C:\NXP\S32DS_ARM_v2018.R1\S32DS\S32SDK_S32K14x_EAR_0.8.6\doc\Start_here.html
