Nios II軟件構(gòu)建工具入門
The Nios® II Software Build Tools (SBT) allows you to construct a wide variety of
complex embedded software systems using a command-line interface. From this
interface, you can execute Software Built Tools command utilities, and use scripts
other tools) to combine the command utilities in many useful ways.
This chapter introduces you to project creation with the SBT at the command line
This chapter includes the following sections:
■ “Advantages of Command-Line Software Development”
■ “Outline of the Nios II SBT Command-Line Interface”
■ “Getting Started in the SBT Command Line”
■ “Software Build Tools Scripting Basics” on page 3–8
使用Nios II軟件構(gòu)建工具
This chapter describes the Nios® II Software Build Tools (SBT), a set of utilities and
scripts that creates and builds embedded C/C++ application projects, user library
projects, and board support packages (BSPs). The Nios II SBT supports a repeatable,
scriptable, and archivable process for creating your software product.
You can invoke the Nios II SBT through either of the following user interfaces:
■ The Eclipse™ GUI
■ The Nios II Command Shell
The purpose of this chapter is to make you familiar with the internal functionality of
the Nios II SBT, independent of the user interface employed.

Firmware in embedded hardware systems is frequently updated over the Ethernet. For
embedded systems that comprise a discrete microprocessor and the devices it controls, the
firmware is the software image run by the microprocessor. When the embedded system
includes an FPGA, firmware updates include updates of the hardware image on the FPGA. If
the FPGA includes a Nios® II soft processor, you can upgrade both the Nios II processor—as
part of the FPGA image—and the software that the Nios II processor runs, in a single remote
configuration session.
面向Eclips的Nios II軟件構(gòu)建工具手冊
The Nios® II Software Build Tools (SBT) for Eclipse™ is a set of plugins based on the
Eclipse™ framework and the Eclipse C/C++ development toolkit (CDT) plugins. The
Nios II SBT for Eclipse provides a consistent development platform that works for all
Nios II embedded processor systems. You can accomplish all Nios II software
development tasks within Eclipse, including creating, editing, building, running,
debugging, and profiling programs.

Nios® II embedded processor cores can contain instruction and data caches. This
chapter discusses cache-related issues that you need to consider to guarantee that
your program executes correctly on the Nios II processor. Fortunately, most software
based on the Nios II hardware abstraction layer (HAL) works correctly without any
special accommodations for caches. However, some software must manage the cache
directly. For code that needs direct control over the cache, the Nios II architecture
provides facilities to perform the following actions:
