milkv-duo environment compilation
基于milkv-duo环境编译
Milk-V Duo是一个基于CV1800B芯片的超紧凑嵌入式开发平台。它可以运行Linux和RTOS，为专业人士、工业ODM厂商、AIoT爱好者、DIY爱好者和创作者提供了一个可靠、低成本和高性能的平台。

添加一些package
source ./build/cvisetup.sh
defconfig cv1800b_milkv_duo_sd
menuconfig
# 可以添加或者删除一些软件和配置
编译打包
可以查看env.sh源代码
说明每个平台是不一样，希望大家稍微修改哈

build_all
pack_sd_image
执行如下命令：
# 第一次编译时候可以用
./env.sh
# 不是第一次编译时候可以用，先清理缓存
# ./env.sh arg1 arg1表示参数1，内容没固定，随便写
./env.sh 1
或者想在镜像添加一些文件，如python，gdb等，需要如下命令：
source ./build/cvisetup.sh
defconfig cv1800b_milkv_duo_sd
menuconfig
# 可以选择你喜欢的东西，然后可以运行
build_all
pack_sd_image
image
上述步骤，正常运行编译打包，导出image镜像，如下：
install/soc_cv1800b_milkv_duo_sd/milkv-duo.img
烧录方式可以是SD卡或者其他工具
判断是否成功
测试ping 192.168.42.1
需要安装依赖驱动哈
建议
- 不要安装在Windows系统下编译
- 即是在Windows用wsl环境下配置，不建议
- 在Linux或者容器或者虚拟机，不要直连Windows下路径，有时候莫名其妙出一些问题
- 搬抄按照步骤去做，发现有一些依赖文件没安装，需要分析一下
