Page 4: Introduction
1. Introduction 1.1. Overview This document is a quick start guide for the NOEL-ARTYA7-EX design. The guide is mainly how-to oriented and does not go into many technical details. For more in-depth information we refer to respective products User's Manual. See the reference list below. -
Page 5: Overview
Linux 64-bit host operating systems. Chapter 5 describes how to use RTEMS with NOEL-ARTYA7-EX. The recommended method to load software onto NOEL-ARTYA7-EX is by connecting to a debug interface of the board through the GRMON hardware debugger (Chapter 4). -
Page 6: Bare C Cross-Compiler
Included in the software development environment is a NOEL-ARTYA7-EX BSP for Buildroot which provides the necessary driver support. See Chapter 7 for instructions on how to create a Linux image for NOEL-ARTYA7-EX with Buildroot. 2.4.4. VxWorks 7 Please contact support@gaisler.com for information about NOEL-V BSPs for VxWorks 7. -
Page 7: Board Configuration
• Ethernet PHY SGMII interface with RJ-45 connector. See (Chapter 4). 3.5. Memories The NOEL-ARTYA7-EX has 256 MiB of SDRAM available on the on-chip bus. 3.6. Programming the bitstream A Xilinx Vivado script to program the FPGA is provided with the bitfile distribution. The bitstream folder contains several bistreams which represent different configurations of the processor (EX1,EX2, ecc.). -
Page 8: Grmon Hardware Debugger
The first step is to set up a debug link in order to connect to the board. The following section outlines which debug interfaces are available and how to use them on the NOEL-ARTYA7-EX design. After that, a basic first inspection of the board is exemplified. -
Page 9: Debug-Link Alternatives
The previous sections have described which debug-links are available and how to start using them with GRMON. The subsections below assume that GRMON, the host computer and the NOEL-ARTYA7-EX board have been set up so that GRMON can connect to the board. -
