代码

设备树对应的文件是100ask_imx6ull_mini.dtb
所以需要在根节点上增加相关的测试代码

我们修改的就是hi如下的代码部分
增加测试节点

    test1:test1{#addrsee-cells = < 1 >;#size-cells = < 1 >;compatible = "test1";reg =< 0x20ac000 0x0000004>;};

修改测试节点的参数

&test1 {compatible = "test1111";state = "okay";
};

下面的内容就是完整的代码

操作脚本

Linux中的操作

编译内核以及编译设备树

cd /home/book/100ask_imx6ull_mini-sdk/Linux-4.9.88

清除之前的编译信息

make mrproper

配置编译的内容

make 100ask_imx6ull_mini_defconfig

编译内核

 make zImage -j4

编译设备树

make dtbs

拷贝两个文件

cp arch/arm/boot/zImage ~/nfs_rootfs

cp arch/arm/boot/dts/100ask_imx6ull_mini.dtb ~/nfs_rootfs

编译内核模块

make modules

 make ARCH=arm INSTALL_MOD_PATH=/home/book/nfs_rootfs modules_install

下位机中的操作指令

配置IP地址

ifconfig eth0 192.168.5.9

挂载mnt目录，如果挂载不成功，可能是IP没有配置，或者配置的不成功，修改IP后就可以

mount -t nfs -o nolock,vers=3 192.168.5.11:/home/book/nfs_rootfs /mnt

将三个文件拷贝到对应的目录下

cp /mnt/zImage /boot

这里的路径韦东山的教程写的是错的，需要将root改成boot

cp /mnt/100ask_imx6ull_mini.dtb /boot

cp /mnt/lib/modules /lib -rfd

使用代码更新

sync

更新完成后重启开发板

查看设备树

cd /proc/device-tree/
