PetaLinux安装详解(Xilinx , linux, zynq, zynqMP)

1 概述

PetaLinux 工具提供在 Xilinx 处理系统上定制、构建和调配嵌入式 Linux 解决方案所需的所有组件。该解决方案旨在提升设计生产力，可与 Xilinx 硬件设计工具配合使用，以简化针对 Versal、Zynq™ UltraScale+™ MPSoC、Zynq™ 7000 SoC、和 MicroBlaze™ 的 Linux 系统开发。

PetaLinux 工具可帮助简化基于 Linux 产品的开发；您可以使用下列工具来完成从系统启动到执行的所有操作：

命令行接口
应用、器件驱动程序、库生成器以及开发模板
可引导的系统映像生成器
调试代理程序
GCC 工具
集成的 QEMU 全系统仿真器
自动化工具
支持系统调试器

嵌入式软件与生态系统:

使用这些工具，开发人员可以定制引导载入程序、Linux 内核或 Linux 应用。他们可以通过网络或 JTAG 在随附的全系统仿真器 (QEMU) 或物理硬件上添加新的内核、器件驱动程序、应用和库，以及启动并测试软件协议栈。

2.2 安装

安装命令：

$ ./petalinux-v2020.1-final-installer.run

安装过程中选择默认就可以了

3 使用

3.1 启动环境配置

james@james-desktop:~$ source /opt/xilinx/petalinux/2020.1/settings.sh
PetaLinux environment set to '/opt/xilinx/petalinux/2020.1'

3.2 使用

调用petalinux-create命令有如下输出，说明安装成功了。

james@james-desktop:~$ petalinux-create
