Petalinux版本信息查询

每个Xilinx Petalinux工具版本都会在官网有一个AR来具体说明。所有版本说明的AR的名称会按照如下格式来命名，PetaLinux XXXX.X - Product Update Release Notes and Known Issues。例如你要找2021.1版本的话，可以在官网搜索PetaLinux 2021.1 - Product Update Release Notes and Known Issues就能直接找到了。在这个AR中会有一个列表介绍当前版本下所有petalinux工具相关的版本信息。

Petalinux

安装依赖，

$ sudo apt install ssh make tftp-hpa tftpd-hpa dos2unix iproute2 gawk xvfb git make net-tools libncurses5-dev zlib1g-dev libssl-dev flex bison libselinux1 gnupg wget diffstat chrpath socat xterm autoconf libtool tar unzip texinfo gcc-multilib build-essential libsdl1.2-dev libglib2.0-dev screen pax gzip zlib1g:i386 minicom u-boot-tools mtd-utils

安装，

$ mkdir -p /opt/Xilinx/Petalinux/2019.2
$ ./petalinux-v2019.2-final-installer.run /opt/Xilinx/Petalinux/2019.2
$ sudo dpkg-reconfigure dash #选择no

建立工程，可以创建空白工程，也可以从bsp创建工程，

# 空白工程
$ petalinux-create -t project -n zynq-v2018.2 --template zynq
$ cp ~/project/fdk/pcierc-zc706/pcierc_wrapper.hdf ./zynq-v2018.2
$ cd zynq-v2018.2
$ petalinux-config --get-hw-description=.
# 从bsp创建工程
$ petalinux-create -t project -s ./zynq-v2018.2.bsp

系统配置，可配置生成的固件这些参数，Yocto相关参数配置都在这里，

$ petalinux-config

配置rootfs，

$ petalinux-config -c rootfs

配置内核，发现默认的内核路径为build/tmp/work/plnx_zynq7-xilinx-linux-gnueabi/linux-xlnx/4.14-xilinx-v2018.2+gitAUTOINC+ad4cd988ba-r0/linux-plnx_zynq7-standard-build，

$ petalinux-config -c kernel

编译，

$ petalinux-build

生成SDK，默认的SDK安装包在<proj_proot>/images/linux/sdk.sh，通过在rootfs中加入packagegroup-petalinux-qt，packagegroup-petalinux-opencv，可以制作出支持Qt和OpenCV的交叉编译工具链。

$ petalinux-build --sdk

安装SDK，默认的SDK安装路径在<proj_proot>/images/linux/sdk/，

$ petalinux-package --sysroot
PetaLinux SDK installer version 2018.2
======================================
You are about to install the SDK to "/home/qe/project/petalinux/zynq-v2018.2/images/linux/sdk". Proceed[Y/n]? Y
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.$ . /home/qe/project/petalinux/zynq-v2018.2/images/linux/sdk/environment-setup-cortexa9hf-neon-xilinx-linux-gnueabi

使用Yocto工具的步骤，新建工程后需要使用petalinux-config或petalinux-config --oldconfig，完成基本环境创建。

$ source ~/program/petalinux-v2018.2-final/components/yocto/source/arm/environment-setup-cortexa9hf-neon-xilinx-linux-gnueabi

下面就可以愉快的使用yocto的工具来开发了，修改内核/home/qe/program/petalinux-v2018.2-final/components/yocto/source/arm/workspace/sources/linux-xlnx测试一下，报错，找不到openamp.scc，但是这个文件在默认的内核路径为build/tmp/work/plnx_zynq7-xilinx-linux-gnueabi/linux-xlnx/4.14-xilinx-v2018.2+gitAUTOINC+ad4cd988ba-r0确实存在。进入这个目录来测试，还是不行，而且petalinux-config -c kernel也不能用了。把recipe reset之后petalinux-config -c kernel可以用了，所以，尝试在petalinux使用外部源代码来解决这个问题吧，当然需要make mrproper一下，刚看了官方好像是bitbake virtual/kernel -c menuconfig，算了，不测试了。

添加自己的固件文件到根文件系统，注意这个时候和APP不一样，你的FILES_${PN}一定要写，

$ petalinux-create -t apps --template install --name myfw --enable

petalinux-build卡住在source bitbake很久都没动，执行一下clean才能编，

petalinux-build -x distclean

添加驱动，删除驱动除了删除模块目录之外，您还必须从<plnx-proj-root>/project-spec/meta-user/recipes-core/images/petalinux-image.bbappend中删除行：IMAGE_INSTALL_append= "mymodule"。删除目录但保留petalinux-image-full.bbappend中的上述程序行将出错。

$ petalinux-create -t modules --name broadcom-wl --enableINFO: Create modules: broadcom-wl

编译，

$ petalinux-build
$ petalinux-build -c broadcom-wl

生成uImage，如果你想在zynq平台上使用jffs2，zynqmp平台不支持这个命令，

$ petalinux-package --image -c kernel --format uImage

创建BOOT.BIN，

# $ petalinux-package --boot --fsbl <FSBL_ELF> --fpga <BITSTREAM> --u-boot --pmufw <PMUFW_ELF>
#   It will generate a BOOT.BIN in your working directory with:
#     * specified <BITSTREAM>
#     * specified <FSBL_ELF>
#     * specified < PMUFW_ELF > *
#     * newly built u-boot image which is <PROJECT>/images/linux/u-boot.elf# 3合1
$ petalinux-package --boot --fpga images/linux/pcierc_wrapper_gen2_x4.bit --u-boot --force
# 2合1
$ petalinux-package --boot --u-boot --force

配置自动登录，

# Select Yocto-settings > Enable debug-tweaks
$ petalinux-config

添加自启动程序，采用install类型的模板，只需要把自己的应用命名为myapp部署到/usr/bin就可以了，而petalinux的${bindir}就代表/usr/bin，

$ petalinux-create -t apps --template install -n myfw-init --enable
$ cat project-spec/meta-user/recipes-apps/myfw-init/myfw-init.bb
#
# This file is the myfw-init recipe.
#SUMMARY = "Simple myfw-init application"
SECTION = "PETALINUX/apps"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"SRC_URI = "file://myfw-init \"S = "${WORKDIR}"inherit update-rc.d
INITSCRIPT_NAME = "myfw-init"
INITSCRIPT_PARAMS = "start 99 S ."do_install() {install -d ${D}${sysconfdir}/init.dinstall -m 0755 ${S}/myfw-init ${D}${sysconfdir}/init.d/myfw-init
}
FILES_${PN} += "${sysconfdir}/*"
$ cat project-spec/meta-user/recipes-apps/myfw-init/files/myfw-init
#!/bin/shDAEMON=/usr/bin/myapp
start ()
{echo " Starting myapp"start-stop-daemon -S -o --background -x $DAEMON
}
stop ()
{echo " Stoping myapp"start-stop-daemon -K -x $DAEMON
}
restart()
{stopstart
}
[ -e $DAEMON ] || exit 1case "$1" instart)start; ;;stop)stop; ;;restart)restart; ;;*)echo "Usage: $0 {start|stop|restart}"exit 1esac
exit $?

删除自己的应用，直接删除应用的文件夹，然后注释掉IMAGE_INSTALL_append= " ***"，

# <plnx-proj-root>/project-spec/meta-user/recipes-core/images/petalinux-image-full.bbappend
IMAGE_INSTALL_append= " ***"

发布bsp，

$ petalinux-package --bsp -o zynq-v2018.2.bsp -p .
$ petalinux-package --bsp -o zynq-v2018.2.bsp -p . --force

连着vivado工程一起打包，clean表示把vivado工程清除后再发布，减少文件体积，

$ petalinux-package --bsp -o zynq-v2018.2.bsp -p . --hwsource <PATH_TO_HARDWARE_PROJECT> --force
$ petalinux-package --bsp -o zynq-v2018.2.bsp -p . --hwsource <PATH_TO_HARDWARE_PROJECT> --force --clean

设置下载缓存

参考AR711989，

This is a known issue in 2017.2-2017.4 PetaLinux if BB_NO_NETWORK is set to 1, and the local download directory is set to PREMIRRORS_prepend in the conf file.The PREMIRRORS variable will have SOURCE_MIRROR_URL as the first URL.This causes build to fail as network access is disabled. PREMIRRORS should be appended here so that a prepend in other layers/conf files takes precedence.To work around this issue follow the steps below:1) Run petalinux-config ---> Yocto Settings ---> Add pre-mirror url ---> file:///opt/xilinx/petalinux/sstate-rel-v2017.4/downloads2) Run petalinux-config ---> Yocto Settings ---> Local sstate feeds settings ---> /opt/xilinx/petalinux/sstate-rel-v2017.4/aarch64 3) Run petalinux-config ---> Yocto Settings ---> Network sstate feeds URL ---> http://petalinux.xilinx.com/sswreleases/rel-v${PETALINUX_VER}/aarch64/sstate-cache  //Keep this as the default generated from PetaLinux tools4) Run petalinux-config ---> Yocto Settings ---> [*] Enable BB NO NETWORK    //This is mandatory when you do not have network access on build machines.5) Add this content in <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf and make sure that this path matches with the pre-mirror URL path mentioned above.PREMIRRORS_prepend = " git://.*/.* file:///opt/xilinx/petalinux/sstate-rel-v2017.4/downloads \n \
ftp://.*/.* file:///opt/xilinx/petalinux/sstate-rel-v2017.4/downloads \n \

去掉不需要的image，

# project-spec/meta-user/conf/petalinuxbsp.conf
#Remove all qemu contents
IMAGE_CLASSES_remove = "image-types-xilinx-qemu qemuboot-xilinx"
IMAGE_FSTYPES_remove = "wic.qemu-sd tar.gz tar.bz2 ext3 ext3.bz2 cpio.bz2 cpio.xz cpio.lzma cpio.lz4"

增加软件包

petalinux采用yocto来制作跟文件系统，比如iperf3，在petalinux rootfs的menuconfig中是没有的，需要手动配置，iperf3 recipe位置在，

zc@ubuntu:~/program/petalinux-v2018.2-final/components/yocto/source/aarch64/layers/meta-openembedded/meta-oe/recipes-benchmark/iperf3$ ls -l
total 8
drwxr-xr-x 2 zc zc 4096 Jun  8  2018 iperf3
-rw-r--r-- 1 zc zc 1171 Jun  8  2018 iperf3_3.2.bb

在工程的meta-user里添加该软件包，双引号里记得加个空格，

zc@ubuntu:~/project/petalinux/zynqmp-v2018.2/project-spec/meta-user/recipes-core/images$ cat petalinux-image.bbappend
#Note: Mention Each package in individual line
#      cascaded representation with line breaks are not valid in this file.
IMAGE_INSTALL_append = " peekpoke"
IMAGE_INSTALL_append = " gpio-demo"
IMAGE_INSTALL_append = " iperf3"

使能该软件包，选中iperf3，

zc@ubuntu:~/project/petalinux/zynqmp-v2018.2$ petalinux-config -c rootfs

编译，

zc@ubuntu:~/project/petalinux/zynqmp-v2018.2$ petalinux-build

对于petalinux-image-full中的recipes，有sstate locked，在project-spec/meta-user/conf/petalinuxbsp.conf文件中添加SIGGENE_UNLOCKED_RECIPES += "my-recipe"来unlock。

zc@ubuntu:~/project/petalinux/zynqmp-v2018.2$ cat project-spec/meta-user/conf/petalinuxbsp.conf
#User Configuration#OE_TERMINAL = "tmux"# Add EXTRA_IMAGEDEPENDS default components
EXTRA_IMAGEDEPENDS_append_zynqmp = " virtual/fsbl virtual/pmu-firmware arm-trusted-firmware"
EXTRA_IMAGEDEPENDS_append_zynq = " virtual/fsbl"
EXTRA_IMAGEDEPENDS_append_microblaze = " virtual/fsboot virtual/elfrealloc"#Remove all qemu contents
IMAGE_CLASSES_remove = "image-types-xilinx-qemu qemuboot-xilinx"
IMAGE_FSTYPES_remove = "wic.qemu-sd"EXTRA_IMAGEDEPENDS_remove = "qemu-helper-native virtual/boot-bin"

修改源代码

2021.1及以后的版本可以直接通过petalinux工具中的命令，把源码下载到当前的petalinux工程中然后直接按照你的需要进行修改。之后petalinux工具会按照你修改后的源码进行编译。命令格式如下：petalinux-devtool modify<recipe-name>，例如：petalinux-devtool modify linux-xlnx，Linux kernel的源码会被下载到<plnx-proj-root>/components/yocto/workspace/sources/<recipe-name>文件夹下。然后就可以直接在这个位置对kernel的源码进行修改，修改完成后直接用petalinux-build就可以编译进去了。如果不知道确切的recipe的名字的话，可以使用petalinux-devtool search <key word>来查找。例如：petalinux-devtool search xen。另外，在2021.1版本之后，FSBL的recipe-name为fsbl-firmware，pmu的recipe-name为pmu-firmware。
2021.1之前的版本通过patch的方式实现源码的修改，利用git工具，先从上面的列表中找到对应的版本，然后先下载下来。git clone -b<version> <source link>，下载之后修改对应的源码，修改完成后回到源码的根目录来生成patch，git add .，把修改的内容添加到本地版本中，git diff <version old> <version new> <xxx.patch>，生成2个版本之间的patch，版本信息可以使用git log或者git status来查看。接下来就可以将生成的patch应用到petalinux工程中去。通常就是修改对应recipe的bbappend文件，把patch添加进去即可。

Petalinux生成的Makefile

petalinux 2015.2.1驱动Makefile，可参考学习一下，

#
