作者使用 AMD Vitis™
系统是ubuntu 22.04.1 LTS
PetaLinux简介
PetaLinux 是一个嵌入式 Linux 软件开发工具包 (SDK),旨在为基于 FPGA 的系统芯片 (SoC) 设计或 FPGA 设计提供支持。
您需要具备以下基本技能:
Linux 基础知识:能够执行 Linux 命令。
操作系统及主机系统功能:了解操作系统版本、Linux 发行版、安全权限,以及 Yocto 的基本概念。
PetaLinux 工具包包含以下组件:
Yocto 可扩展 SDK (eSDK):用于创建和维护嵌入式 Linux 系统。
XSCT 和工具链:用于调试和交叉编译。
PetaLinux 命令行接口 (CLI) 工具:用于在命令行中管理和配置 PetaLinux 项目。
从 2024.1 版本开始,有两种方法可以构建 PetaLinux 镜像。
- XSCT Flow
Using the XSCT flow by providing xsa file as input to petalinux-config. - system-device-tree
Using system-device-tree, you can also build the images without relying on XSCT. The input to petalinux-config is system-device-tree instead of XSA
XSCT and tool chains
PetaLinux tool uses the XSCT underneath to configure and build all the embedded software applications.
- XSCT tool chain path: $PETALINUX/components/xsct
PetaLinux Command Line Interface (CLI) tools
This contains all the PetaLinux commands that you require. The CLI command tools are:
- petalinux-create
- petalinux-config
- petalinux-build
- petalinux-util
- petalinux-package
- petalinux-upgrade
- petalinux-devtool
- petalinux-boot
设置环境
安装需求
-
最低系统要求:
- 8 GB RAM
- 2 GHz CPU clock or equivalent (minimum of eight cores)
- 100 GB free HDD space
- Supported OS:
Completely removed RHEL and CENTOS to align with upstream Yocto.
Ubuntu Desktop/Server 20.04.2 LTS, 20.04.3 LTS, 20.04.4 LTS, 20.04.5 LTS(64-bit),20.04.6 LTS, 22.04 LTS, 22.04.1 LTS, 22.04.2 LTS, and 22.04.3 LTS
OpenSuse Leap 15.3 and 15.4
AlmaLinux 8.7 and 9.1
-
非root用户安装
-
PetaLinux需要在Linux主机工作站上安装标准开发工具和库。在主机Linux上安装发行说明中列出的库和工具。
-
PetaLinux工具要求你的主机系统/bin/sh是"bash"如果您使用的是Ubuntu发行版,并且/bin/sh是"dash",使用sudo dpkg reconfigue dash命令更改默认的系统shell/bin/sh。
要查看系统的默认 /bin/sh,可以使用以下命令在终端中执行:ls -l /bin/sh
安装
-
创建安装目录
mkdir -p /home/<user>/petalinux/<petalinux-version>
-
安装
修改权限chmod 755 ./petalinux-v<petalinux-version>-final-installer.run
petalinux-v<petalinux-version>-final-installer.run -p "aarch64"
其中 -p 指定安装架构,Vitis™是aarch64。

安装过程遇到问题
1、缺少部分包
-
问题描述
[WARNING] This is not a supported OS
[INFO] Checking free disk space
[INFO] Checking installed tools
[ERROR] You are missing the following system tools required by PetaLinux:- xterm
- autoconf
- libtool
- texinfo
- zlib1g-dev
- gcc-multilib
Please check PetaLinux installation guide - required tools and libraries package section for detailed information
[INFO] Checking installed development libraries
[ERROR] You are missing these development libraries required by PetaLinux:- zlib
- ncurses
Please install them with your operating system package manager, and try again
-
解决方法
sudo apt-get update
sudo apt-get install xterm autoconf libtool texinfo zlib1g-dev gcc-multilib zlib1g libncurses5-dev
2、安装失败
- 问题描述
初次安装时,安装包不在安装目录下,安装命令中使用 --dir 未生效,安装失败。 - 解决方法
将安装包复制到安装目录。
3、无tftp服务
-
安装命令
sudo apt update
sudo apt install tftpd-hpa -
配置 TFTP 服务器
vi /etc/default/tftpd-hpa
默认配置:
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/srv/tftp"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure"
可以修改为:
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure"
-
创建 TFTP 根目录
创建 TFTP 根目录,并设置适当的权限sudo mkdir -p /var/lib/tftpboot
sudo chmod -R 777 /var/lib/tftpboot -
重启 TFTP 服务
sudo systemctl restart tftpd-hpa
-
检查 TFTP 服务状态
sudo systemctl status tftpd-hpa
-
测试 TFTP 服务器
你可以使用 TFTP 客户端来测试服务器是否可用。在另一个终端中,输入以下命令:tftp localhost
然后尝试下载或上传文件。例如:
get a.txt
put b.txt
-
注意事项
确保防火墙允许 UDP 69 端口的流量。如果使用 ufw 防火墙,可以使用以下命令打开 TFTP 的端口sudo ufw allow 69/udp
