版本
PETALINUX_VER=2017.4
这里引用的u-boot，kernel，busybox版本分别是：
u-boot ： U-Boot 2017.01
kernel ： 4.9.0-xilinx-v2017.4
busybox ： BusyBox v1.24.1
安装
1.安装必要的库
sudo apt-get install tofrodos gawk xvfb git libncurses5-dev tftpd zlib1g-dev zlib1g-dev:i386 \
libssl-dev flex bison chrpath socat autoconf libtool texinfo gcc-multilib \
libsdl1.2-dev libglib2.0-dev screen pax
2.安装 Petalinux
sudo -s
mkdir -p /opt/pkg/petalinux
chown flinn /opt/pkg/
chgrp flinn /opt/pkg/
chgrp flinn /opt/pkg/petalinux/
chown flinn /opt/pkg/petalinux/
exit
给安装文件添加运行权限
sudo chmod +x petalinux-v2017.4-final-installer.run
./petalinux-v2017.4-final-installer.run /opt/pkg/petalinux/
使用 Petalinux 定制 Linux 系统
依赖文件xx.hdf文件
设置 petalinux 环境变量
运行下面命令
source /opt/pkg/petalinux/settings.sh
这个脚本主要工作如下：
#
# Add toolchains to user's search path
#
PATH="${PETALINUX}/tools/linux-i386/aarch64-none-elf/bin:${PETALINUX}/tools/linux-i386/aarch64-linux-gnu/bin:${PATH}"
PATH="${PETALINUX}/tools/linux-i386/gcc-arm-none-eabi/bin:${PETALINUX}/tools/linux-i386/gcc-arm-linux-gnueabi/bin:${PATH}"
PATH="${PETALINUX}/tools/linux-i386/microblaze-xilinx-elf/bin:${PETALINUX}/tools/linux-i386/microblazeel-xilinx-linux-gnu/bin:${PATH}"
PATH="${PETALINUX}/tools/linux-i386/gcc-arm-none-eabi-r5/bin:${PATH}"
#
# Add required binary tools to the user's search path
#
PATH="${PETALINUX}/tools/linux-i386/petalinux/bin:${PETALINUX}/tools/common/petalinux/bin:${PATH}"
即指定gcc，并添加到环境变量里面
运行下面命令设置 vivado 环境变量
source /opt/Xilinx/Vivado/2017.4/settings64.sh
在这个脚本全部内容如下：
source /opt/Xilinx/Vivado/2017.4/.settings64-Vivado.sh
source /opt/Xilinx/SDK/2017.4/.settings64-SDK_Core_Tools.sh
source /opt/Xilinx/DocNav/.settings64-DocNav.sh
创建工程
petalinux-create --type project --template zynq --name peta_top
cd peta_top
配置 Petalinux 工程的硬件信息
petalinux-config --get-hw-description ../xx.sdk
配置 petalinux 工程
如果配置过后想再次配置，可以运行命令“petalinux-config”来配置。
配置 uboot 和 Linux 内核的来源
默认是 github
配置启动方式
在 Advanced bootable images storage Settings 选项中
默认从 sd 卡启动，为 了调试这里保持默认从 sd 卡启动，如果需要制作一个从 QSPI flash 启动的嵌入式 Linux， 可以在这里配置
以上配置主要针对u-boot的，详细可以参考最后章节‘附录’
配置 Linux 内核
petalinux-config -c kernel
配置根文件系统
petalinux-config -c rootfs
编译
使用下面命令配置编译 uboot、内核、根文件系统、设备树等
petalinux-build
生成 BOOT 文件
petalinux-package --boot --fsbl ./images/linux/zynq_fsbl.elf --fpga --u-boot --force
烧写
images/linux 目录中的 BOOT.BIN 和 image.ub 复制到 sd 卡 ，从sd卡启动
使用 root 登录，默认密码 root，插上网线后（路由器支持自动获取 IP），使用 ifconfig 命 令可以看到网络状态
日志
最后启动日志：
