Introduction

The NXP S32K144 Board is low-cost evaluation and development board for general-purpose industrial and automotive applications from the manufacturer NXP. The device is based on the 32-bit Arm^® Cortex^®-M4F architecture with 64kB of RAM and 524kB of FLASH. It is capable as an application controller for the iRJ45/SoM module.

Software

Integrated Development Environment

The S32 Design Studio by NXP is a free Integrated Development Environment which provides several utilities to develop and debug applications for the S32K144 Board. It is available on the NXP website.

Building, Flashing and Project Generation

For compiling the example code, the GNU Arm Embedded Toolchain is required. This Toolchain is provided by the S32 Design Studio or it can be obtained in several ways. Further information can be found here: Downloads | GNU Arm Embedded Toolchain Downloads – Arm Developer.

To flash the application the S32 Design Studio is needed.

We also suggest (to all Windows User) using MSYS to use our handy project generator, which creates S32 Design Studio projects out of uGOAL.

Getting Started

Preparations

Hardware Requirements

Open

Make sure following settings are set:

• J13 - Connect “iRJ45” with “Sockel”

• J8 - Connect “CS_SOURCE” with “PB2”

• J7 - Connect “RST_SOURCE” with “PD7”

• Set all DIP-Switches to “OFF”

Target System

Connect both boards (see Figure above). Voltage supply is done through the VCC33_Sockel by the S32K144.

Using delivered build system

Build

Within a example folder ugoal/projects/ugoal/<example name>/gcc of the software delivery, build the firmware with following commands:

If you want to clean the build, use following command:

Using S32 Design Studio by NXP

Automated project generation

From any project folder a project generator can be run to create a S32 Design Studio project for the application. The project generator requires a python3 installation. Required dependencies are installed automatically.

If you want to create a S32 Design Studio project, run the following command:

For the S32K144 the template number 4 needs to be chosen.

The generated project should be imported into S32 Design Studio using “Import → Existing Projects into Workspace” and by browsing to the project folder. You might have to add a Debug Configuration. This is done by clicking the Debug Icon in the Toolbar and select “Debug Configurations…”.

The S32K144 can be debugged with the installed GDB PEMicro Interface. You only have to select the Device as shown below.

Executable: ${S32DS_ARM32_TOOLCHAIN_DIR}/bin/${arm32_cross_prefix}gdb${arm32_cross_suffix}

Using Processor Expert

The S32DS contains a tool for a simple start in configuring peripheral devices and pins of the NXP S32DS. uGOAL comes with his own configuration including SPI, UART, I2C and GPIOs.

This Page gives you an overview for the Processor Expert Tool.

Debugging

UART

The UART-interface of the S32K144 is accessable through the connected USB port. You can access the UART by launching a serial monitor like putty. Choose the following settings:

Application

After setting up the serial monitor and starting the application, the output should look like this:
