如何配置petalinux使用本地kernel、u-boot、rootfs-爱代码爱编程

Posted on2021-04-16 分类: linux zynq

文章目录

1. 配置petalinux工程

1.1 导入vivado的hdf文件

  • 进入工程目录后：
petalinux-config --get-hw-description ../../hdf/Navigator_7020.sdk/

1.2 配置源码来源

  • 将特定源码拷贝至Ubuntu中，借助petalinux的petalinux-config令打开图形化界面命配置u-boot来源
  • 同理配置内核来源

1.3 配置根文件系统类型为SD CARD

  • 借助petalinux的petalinux-config令打开图形化界面命配置根文件系统类型为SD CARD

2.配置设备树

  • 下面目录下存储了设备树的配置信息，存储在system-user.dtsi文件中
~/petalinux/ALIENTEK-ZYNQ/project-spec/meta-user/recipes-bsp/device-tree/files
  • 设备树文件实例：
/include/ "system-conf.dtsi"
#include <dt-bindings/gpio/gpio.h>

3. 编译petalinux工程

  • 返回工程的根目录，使用petalinux-build进行全编译
  • 打包生成BOOT.BIN文件和image.ub文件
petalinux-package --boot --fsbl --fpga --u-boot --force
# 若后面不跟路径则自动在所在工程目录下寻找可用的文件，执行完毕后打印输出所用文件

4. 制作SD卡

4.1 设置SD卡分区为2个

#插入SD卡至PC
#由于之前制作的SD卡中没有包含文件系统，因此需要重新制作

ar@ar:~/petalinux/ALIENTEK-ZYNQ$ df -h  #查看挂载的SD卡

#卸载SD卡
ar@ar:~/petalinux/ALIENTEK-ZYNQ$ umount /media/ar/boot 
#对SD卡进行配置
ar@ar:~/petalinux/ALIENTEK-ZYNQ$ sudo fdisk /dev/sdb

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

4.2 格式化SD卡

#格式化分区1
ar@ar:~/petalinux/ALIENTEK-ZYNQ$ sudo mkfs.vfat -F 32 -n boot /dev/sdb1
mkfs.fat 3.0.28 (2015-05-16)
mkfs.fat: warning - lowercase labels might not work properly with DOS or Windows

#格式化分区2
ar@ar:~/petalinux/ALIENTEK-ZYNQ$ sudo mkfs.ext4 -L rootfs  /dev/sdb2

4.3 分区挂载

  • 完成上述步骤后只需要点击左侧菜单的最下面两个USB图标即可完成挂载，一个USB图标对应一个分区。
ar@ar:~/petalinux/ALIENTEK-ZYNQ/images/linux$ df -h
文件系统        容量  已用  可用 已用% 挂载点
udev            4.2G     0  4.2G    0% /dev

/dev/sdb2        15G   37M   14G    1% /media/ar/rootfs
  • 可见最后两行分别是SD卡的分区1/2，完成挂载。

4.4 将目标文件拷贝至两个分区

  • 将BOOT.BIN和image.ub文件拷贝至分区1
ar@ar:~/petalinux/ALIENTEK-ZYNQ/images/linux$ cp -a BOOT.BIN image.ub /media/ar/boot/
ar@ar:~/petalinux/ALIENTEK-ZYNQ/images/linux$ sync
  • 将根文件系统拷贝到共享文件夹后解压至分区2
 cd /mnt/hgfs/share/
ar@ar:/mnt/hgfs/share$ ls
rootfs-qt5-atk.tar.gz

ar@ar:/mnt/hgfs/share$ df -h
