1. ubuntu下vscode搭建嵌入式Linux开发环境
1.1. 安装vscode及插件
官网下载deb安装包后执行 sudo dpkg -i XXX.deb 或者从文件夹双击.下载链接:https://code.visualstudio.com/Download ；
安装以下插件
1.C/C++
2.C/C++ CLang command adaper
3.C++ intellisense
4.GBKtoUTF8
5.include Autocomplete
6.rainbow Brackets
在vscode欢迎界面点击【Add workspace folder】，然后添加自己的linux内核源码根目录。
新建应用程序目录（里面有你的程序源码和makefile文件），该目录可以存放在你想存放的任何路径下，然后 在vscode软件中点击【File】->【add folder to workspace】选项，选择刚刚建立的自己的程序目录，如图是我本人的内核源码目录和应用程序目录。
【File】->【save workspace as …】保存工作空间,命名vscode_workspace。注:工作空间的名字与路径随意。
1.2. 添加内核include目录
修改vscode配置文件，使其能找到头文件
在vscode 选择inux内核路径，然后 按快捷键”Ctrl + Shift + P”, 然后搜索>Edit configurations ， 单击后，会打开一个c_cpp_properties.json文件，该文件在.vscode里面，也可以手动打开。添加自己的内核目录
"includePath": [
"${workspaceFolder}/**",
"/home/book/NUC970/NUC970_Linux_Kernel/include",
"/home/book/NUC970/NUC970_Linux_Kernel/arch/arm/include",
"/home/book/NUC970/NUC970_Linux_Kernel/arch/arm/mach-nuc970/include"
],
1.3. 添加宏定义
找到内核autoconf.h 文件，位于内核源码的/include/generated/路径下。
/home/book/NUC970/NUC970_Linux_Kernel/include/generated/autoconf.h
autoconf.h 文件是C格式的，如下
#define CONFIG_HAVE_ARCH_SECCOMP_FILTER 1
#define CONFIG_SCSI_DMA 1
#define CONFIG_KERNEL_GZIP 1
#define CONFIG_ATAGS 1
#define CONFIG_CRC32 1
#define CONFIG_I2C_BOARDINFO 1
#define CONFIG_AEABI 1
………………………………………………………………
~~~~~~~~~~~~~~~~~~~~~~~~~
等等等等
而我们配置文件c_cpp_properties.json里面宏定义必须去掉#define，且需要加双引号，比如
#define CONFIG_HAVE_ARCH_SECCOMP_FILTER 1
需要改为
"CONFIG_HAVE_ARCH_SECCOMP_FILTER 1"
#define CONFIG_UEVENT_HELPER_PATH "/sbin/hotplug"
需要改为
"CONFIG_UEVENT_HELPER_PATH \"/sbin/hotplug\" "
#define CONFIG_DEFAULT_HOSTNAME "(none)"
需要改为
"CONFIG_DEFAULT_HOSTNAME \"(none)\" "
#define CONFIG_CMDLINE "noinitrd root=/dev/mtdblock2 rootfstype=yaffs2 rootflags=inband-tags console=ttyS0, 115200n8 rdinit=/sbin/init mem=64"
需要改为
"CONFIG_CMDLINE \"noinitrd root=/dev/mtdblock2 rootfstype=yaffs2 rootflags=inband-tags console=ttyS0, 115200n8 rdinit=/sbin/init mem=64\""
等等，上面对于宏定义自己带"的情况下需要加转义字符\
最终改过后的如下，还需在最前面加上"__KERNEL__", 总之不能让c_cpp_properties.json文件报错

然后拷贝刚修改的 “includePath”: [] 和 “defines”: []，到自己应用程序目录下.vscode/c_cpp_properties.json 里面去，即确保内核和自己的应用程序都能找得到。
1.4. 设置左侧目录不自动展开
左侧目录中包含了linux源码，默认打开一个文件，默认会自动展开并定位到该文件。
在驱动开发中关闭该功能会有更好的体验，方式如下：
a.按Ctrl+Shift+P快捷键，然后输入setting，从下拉选择中找到“Open settings(JSON)”
b.在打开的文件中输入 “explorer.autoReveal”: false
如下
{
"explorer.autoReveal": false
}
下面就可以愉快的玩耍了。
