recommends that users have some experience with embedded Linux development on other embedded systems or they have read the Getting Started with Embedded Linux guide for their platform. Before creating custom hardware or using the Linux kernel, Digilent Inc. The Appendix: How to Debug the Linux Kernel introduces you to some simple debugging techniques to follow when errors occur with the Linux kernel. During the compilation and running of The Linux kernel on your customized hardware, there is a chance that the kernel will panic and generate an Oops message or completely cease functioning. This section also provides information for building and customizing the kernel, file system customization, and finally running the Linux kernel on ZYNQ AP SoC based boards. This section demonstrates customizable features useful for custom hardware design. After explaining all the prerequisites for running The Linux kernel (boot loaders, device trees, etc.), the guide moves to configuring the Linux kernel in Section IV: Linux Kernel Configuration. Section III presents preliminary knowledge about how to configure and build U-Boot, and provides an introduction of some commonly used U-Boot commands. Section III: U-Boot The Embedded Boot Loader introduces U-Boot, a popular boot loader for Linux used by many embedded systems.
Section II takes a closer look at a data structure called the Device Tree Blob (DTB), explains how to write a Device Tree Source (DTS) file, and how to compile the source into a DTB file. Section II: Device Tree Describe Your Hardware to the Linux Kernel examines how the Linux kernel gathers information about the customized hardware.
This section then illustrates the ZYNQ AP SoC basic architecture and explains how to create customized hardware using Xilinx Platform Studio (XPS) available in the Xilinx ISE Design Suite WebPack. Section I: Hardware Customization begins with the Linux Hardware Design Package for ZYNQ AP SoC boards, available on the Digilent Inc. This guide takes a bottom-up approach by starting from a hardware design on the ZYNQ AP SoC Board, moving through the necessary preliminary processes, and eventually giving instructions for running and debugging the Linux kernel. 1 Embedded Linux Development Guide Revision: January 14, NE Henley Court, Suite 3 Pullman, WA (509) Voice (509) Fax This Embedded Linux Development Guide will provide some preliminary knowledge on how to build Linux for Digilent boards based on the Zynq-7000 TM All-Programmable System-on-Chip (ZYNQ AP SoC) to suit your customized hardware designs.
