1.首先搭建硬件环境（导出hdf文件）

1）进入vivado工程选择合适的板子型号，题主的板卡是zc706,芯片型号如下：

2）创建IPdesign

3）本文硬件上，将在ZYNQ Processing system里启用TTC、UART、SD以及之后可能用到的USB、Ethernet（网口0在bank1，bank1电压要选1.8V，否则报错）

MDIO也得选

4）然后automation自动连接外设

5）generate block design and generate output products

选择global

6)create HDL wrapper

7) 然后综合和implement,最后export hardware 生成hdf硬件描述语言

2.petalinux构建镜像文件

2.1步骤：

1.创建petalinux工程

2.将.hdf文件导入petalinux工程中

3.配置petalinux工程（配置内核，配置uboot,以及根文件系统）

4.编译petalinux工程（uboot镜像，内核镜像，rootfs,bitstream,fsbl镜像文件）

5.启动开发板子

2.2实践：

进入petalinux目录

命令说明

petalinux -boot 启动开发板

petalinux -build编译

petalinux -config 配置

petalinux -create 创建

petalinux -package 打包

z@ubuntu:~/PetaLinux2019.1$ petalinux-create --help
petalinux-create             (c) 2005-2019 Xilinx, Inc.

This command creates a new PetaLinux Project or component

Usage:
  petalinux-create [options] <-t|--type <TYPE> <-n|--name <COMPONENT_NAME>

Required:
  -t, --type <TYPE>                     Available type:
                                          * project : PetaLinux project
                                          * apps    : Linux user application
                                          * modules : Linux user module
  -n, --name <COMPONENT_NAME>           specify a name for the component or
                                        project. It is OPTIONAL to create a
                                        PROJECT. If you specify source BSP when
                                        you create a project, you are not
                                        required to specify the name.
Options:
  -p, --project <PROJECT>               specify full path to a PetaLinux project
                                        this option is NOT USED for PROJECT CREATION.
                                        default is the working project.
  --force                               force overwriting an existing component
                                        directory.
  -h, --help                            show function usage
  --enable                              this option applies to all types except
                                        project.
                                        enable the created component

Options for project:
  --template <TEMPLATE>                 zynqMP|zynq|microblaze
                                        user needs specify which template to use.
  -s|--source <SOURCE>                  specify a PetaLinux BSP as a project
                                        source.

Options for apps:
  --template <TEMPLATE>                 <c|c++|autoconf|install>
                                        c   : c user application(default)
                                        c++ : c++ user application
                                        autoconf: autoconf user application
                                        install: install data only
  -s, --source <SOURCE>                 valid source name format:
                                          *.tar.gz, *.tgz, *.tar.bz2, *.tar,
                                          *.zip, app source directory

Options for modules: (No specific options for modules)

EXAMPLES:

Create project from PetaLinux Project BSP:
  $ petalinux-create -t project -s <PATH_TO_PETALINUX_PROJECT_BSP>

Create project from template:
For microblaze project,
  $ petalinux-create -t project -n <PROJECT> --template microblaze
For zynq project,
  $ petalinux-create -t project -n <PROJECT> --template zynq
For zynqMP project,
  $ petalinux-create -t project -n <PROJECT> --template zynqMP


Create an app and enable it:
  $ petalinux-create -t apps -n myapp --enable
The application "myapp" will be created with c template in:
  <PROJECT>/project-spec/meta-user/recipes-apps/myapp


Create an module and enable it:
  $ petalinux-create -t modules -n mymodule --enable
The module "mymodule" will be created with template in:
  <PROJECT>/project-spec/meta-user/recipes-modules/mymodule

1.创建工程

z@ubuntu:~/PetaLinux2019.1$ petalinux-create -t project --template zynq -n zynq_linux 
INFO: Create project: zynq_linux
INFO: New project successfully created in /home/z/PetaLinux2019.1/zynq_linux

2.将hdf 文件导入到工程中

导入成功进入字符图形配置界面

下面要配置开发板的调试串口

默认为uart_1为调试串口

首次运行比较慢。

直接运行petalinux-config直接打开界面

z@ubuntu:~/PetaLinux2019.1/zynq_linux$ petalinux-config --get-hw-description /home/z/hdf/petalinux_smallsystem.sdk/
INFO: Getting hardware description...
INFO: Rename design_1_wrapper.hdf to system.hdf
[INFO] generating Kconfig for project
[INFO] menuconfig project


*** End of the configuration.
*** Execute 'make' to start the build or try 'make help'.

[INFO] sourcing bitbake
[INFO] generating plnxtool conf
[INFO] generating meta-plnx-generated layer
[INFO] generating user layers
[INFO] generating machine configuration
[INFO] generating bbappends for project . This may take time !

因为太慢了我把处理器的内核改了一下，改成3GB，八核。然后终于成功了。

3.下面：petalinux-config -c u-boot 等待一段时间跳出图形化界面

然后在另外一个终端打开字符图形化界面：

同理

4.petalinux-config -c kernel

5.petalinux-config -c rootfs

6.编译整个petalinux工程，也可以单独编译0

petalinux-build

最后生成的结果是在images/linux生成镜像文件

7.制作启动镜像文件BOOT.bin文件

boot.bin是多个镜像文件组合而成的，包括fsbl镜像文件，bitstream镜像文件，用户程序镜像文件

petalinux-package --boot --fsbl --fpga --u-boot --force

--boot:生成BOOT.bin镜像文件

--fsbl:用于指向fsbl镜像文件路径

--fpga:用于指向bitstream文件

--u-boot 用于指定u-boot(用户镜像文件）

--force :强制覆盖

z@ubuntu:~/PetaLinux2019.1/zynq_linux/images/linux$ petalinux-package --boot --fsbl ./zynq_fsbl.elf  --fpga ./system.bit --u-boot ./u-boot.elf --force
INFO: File in BOOT BIN: "/home/z/PetaLinux2019.1/zynq_linux/images/linux/zynq_fsbl.elf"
INFO: File in BOOT BIN: "/home/z/PetaLinux2019.1/zynq_linux/images/linux/system.bit"
INFO: File in BOOT BIN: "/home/z/PetaLinux2019.1/zynq_linux/images/linux/u-boot.elf"
INFO: Generating Zynq binary package BOOT.BIN...

image.ub包括kernel,设备树和根文件系统。所有我们只需提供image.ub和BOOT.bin文件就可以了。

8.制作SD启动卡

将image.ub和BOOT.bin拷贝到SD卡的FAT32分区，再插入SD卡启动板卡。

首先将SD卡用读卡器读入，读入进入虚拟机，在虚拟机中查看板卡的挂载点：

z@ubuntu:~/PetaLinux2019.1/zynq_linux/images/linux$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            1.5G     0  1.5G   0% /dev
tmpfs           298M  8.8M  290M   3% /run
/dev/sda1       984G   36G  898G   4% /
tmpfs           1.5G  212K  1.5G   1% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           1.5G     0  1.5G   0% /sys/fs/cgroup
vmhgfs-fuse     932G  623G  309G  67% /mnt/hgfs
tmpfs           298M   48K  298M   1% /run/user/1000
/dev/sdb1        60G  3.4G   57G   6% /media/z/DA18-EBFA

这张卡是旧卡，要把这个设备点卸载掉，创建一个新的FAT32分区。

z@ubuntu:~/PetaLinux2019.1/zynq_linux/images/linux$ umount /media/z/DA18-EBFA

然后再用df命令就找不到挂载点了

下面我们要创建FAT32分区，

z@ubuntu:~/PetaLinux2019.1/zynq_linux/images/linux$ sudo fdisk /dev/sdb
