Getting Started with GreenBox 3 Real-Time Development Platform

Upon unpacking GreenBox 3, please notice that there is an SD card already inserted in the front panel connector labeled "uSDHC" slot. The SD card contains the basic software project that performs the minimum initialization to boot all of the cores of the S32E288 processor, communicates through UART with a host PC and toggles a GPIO pin to blink the User LED, which is also featured on the front panel connector of GreenBox 3.

2.1 Connect Power Supply

Also included with the shipping components of GreenBox 3 is a 12 V DC power supply. Connect the board with the 12 V DC power supply as shown below. Please keep the board powered off for now.

2.2 Connect USB Cable

On the front side of GreenBox 3 take one end of the USB cable and insert it into the "UART" connector. Take the other end of the USB cable and insert it into your PC.

Note: Please see the tutorials section of this guide for steps on how to configure a virtual COM port if your PC does not automatically configure a virtual COM port for GreenBox 3.

2.3 Start Preferred Serial Terminal

Install and open any serial communication terminal. Configure the terminal to be:

• 115200 Baud Rate
• 8 data bits
• No parity
• One stop bit

Note: Please see the tutorials section of this guide to properly install a serial terminal if your PC does not already have one installed.

2.4 Power on the Device

Power on the device by pressing the PWR button.

2.5 Observe

A greeting message of "Hello From GreenBox 3!" will be displayed on the terminal window. Notice that the terminal will prompt you to press any key. Once any keyboard key is pressed, the rest of the program executes that blink the User LED.

Contained in the GreenBox 3 chassis is the printed circuit board (PCB). To access the PCB, jumper settings and additional peripherals, use a hex/allen key to remove the four screws on the bottom of the chassis. Once unscrewed, access to the entirety of GreenBox 3 is allowed.

3.1 GreenBox 3 PCB

There are many integrated circuits (IC) featured in GreenBox 3. Each provides a specific purpose to allow easy development with GreenBox 3. For more in depth information about the additional ICs, jumper descriptions, software access and additional peripherals, please refer to the GreenBox 3 user manual.

Virtual COM Port Enablement

This step is only needed if you discovered your PC did not automatically configure or did not provide a COM port for the UART of GreenBox 3. If this is the first time you are using virtual COM ports, you need to configure your PC accordingly. Use the following link:

Follow the necessary steps when prompted from the installer.
