1 Introduction to VxWorks 7 and the BeagleBone Black Board Overview of VxWorks 7 Quick Start for the BeagleBone Black Board 1 Host Requirements 2 VxWorks 7 Requirements 2 License Requirements 3 USB to Serial Console Driver Requirements 3 Hardware Requirements 3 Overview of VxWorks 7 Quick Start for the BeagleBone Black Board VxWorks 7 Quick Start is a fully configured bootable VxWorks 7 software package that allows you to start your development effort by simply downloading and installing VxWorks 7, booting the board, and coding your application. VxWorks 7 VxWorks 7 includes a set of development tools and software run-time products, at the core of which is the VxWorks real-time operating system (RTOS) with a modular architecture for IoT- ready hardware. This document guides you through software installation, hardware installation, and the creation of your first real-time process (RTP) and your first kernel application that will run on the board. The main page of the VxWorks 7 documentation is available from the Wind River Knowledge Library at VxWorks 7 documentation. To get started with VxWorks 7 in a full development environment, see the VxWorks 7 Getting Started documentation at Getting Started. 1

VxWorks® 7 Getting Started with VxWorks® 7 and the BeagleBone Black Board For information on the VxWorks 7 integrated development environment tool, see the Workbench 4 documentation. BeagleBone Black Board The BeagleBone Black board is an open source hardware design based on the AM335x 1GHz ARM® Cortex-A8. The board includes the following functionality: • 3D graphics accelerator • NEON floating-point accelerator • MicroSD slot • Universal asynchronous receiver transmitter (UART) 6-pin header for serial console access • USB host port • USB client port • Ethernet • HDMI • 2x 46 pin headers • 4GB 8-bit eMMC on-board flash storage • 512MB DDR3 RAM • An input voltage of 5 VDC For more information on the BeagleBone board, see the BeagleBone Board Website. Host Requirements The VxWorks 7 development environment supports Windows and Linux operating systems. For specific information on supported operating systems and hardware architectures for VxWorks 7, go to VxWorks 7 documentation and select Getting Started, then VxWorks 7 Release Notes, Core. Your host must also provide a USB port to communicate with the target over a universal asynchronous receiver transmitter (UART) interface. VxWorks 7 Requirements You must acquire the VxWorks 7 Quick Start prebuilt boot image, VxWorks 7 software, the VxWorks 7 development environment software, and a license file from Wind River. The VxWorks 7 Quick Start development environment includes a prebuilt VxWorks source build (VSB) project and a prebuilt kernel image to save you time. If you must change the VSB project 2

1 Introduction to VxWorks 7 and the BeagleBone Black Board License Requirements option configuration or the VIP component configuration, or you require functionality that is only available in a VxWorks profile, you must download and install a full version of VxWorks 7. For certain network services such as DHCPv4 and telnet, you can change the preconfigured component parameters at run time by editing a configuration file and rebooting the board. For more information, refer to Run Time Kernel Parameter Configuration on page 29. License Requirements The VxWorks 7 and Workbench 4 software require either a node-locked license or a floating license from Wind River. You can use your existing VxWorks 7 and Workbench 4 license to enable VxWorks 7 Quick Start or request a new license from Wind River. NOTE: If you have a floating license, you can configure Workbench to obtain a key from a known server. For more information on licensing Wind River products, go to the Wind River Knowledge Library, select Installation and view the Wind River Product Installation and Licensing video. USB to Serial Console Driver Requirements To access the serial console directly from a USB interface on your host, you need an interface cable and the associated driver to communicate with the serial console. In a small networking environment with a single subnet, Workbench can generally determine the IP address of your target upon a target connection request. However, in a large networking environment where multiple networks are present and the host and target are on different subnets, you must access the serial console on the board to obtain the DHCP-assigned IP address of your target. NOTE: The USB to serial console driver causes the USB port on your host to appear as a serial universal asynchronous receiver transmitter (UART) port. Hardware Requirements To proceed with development on the BeagleBone Black board, you need a power adapter, a micro secure digital (microSD) card, and interconnecting cables. The specific components as follows: 3

VxWorks® 7 Getting Started with VxWorks® 7 and the BeagleBone Black Board • A BeagleBone Black board. • A power adapter for the board that provides 5 VDC at 2.1 Amps (minimum). • A microSD card to host the bootable VxWorks 7 kernel. You may also need a microSD card adapter to provide compatibility between the microSD card and the card slot of your host. The recommended memory capacity for the microSD card is 8 to 32 Gbytes. • A standard Ethernet cable long enough to interconnect the board to your network. • A USB to 6-pin single row header cable such as the FTDI Chip TTL-232R-5V (USB to TTL serial cable) to connect the serial console header to a USB port on your host. For more information on the cable and driver for your host, see the FTDI Website. The components are as follows: 4
