Xilinx 开发环境

交叉编译环境

在 NAS 文件服务器下载 Xilinx SDK 包，有两种安装方式：

  1. 直接解压 sdk.tar.bz2 到任意目录（如 /opt）

  2. 执行 sdk.sh 脚本安装

执行示例：

$ ./sdk.sh 
PetaLinux SDK installer version 2021.2
======================================
Enter target directory for SDK (default: /opt/petalinux/2021.2): 
You are about to install the SDK to "/opt/petalinux/2021.2". Proceed [Y/n]? 
[sudo] rudy 的密码： 
Extracting SDK....................................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
 $ . /opt/petalinux/2021.2/environment-setup-cortexa72-cortexa53-xilinx-linux

使用前需要先执行 source 命令，配置开发环境

$ source /opt/petalinux/2021.2/environment-setup-cortexa72-cortexa53-xilinx-linux

检查是否配置成功

$ aarch64-xilinx-linux-gcc --version
aarch64-xilinx-linux-gcc (GCC) 10.2.0
