自动构建Debian Ubuntu等发行版本系统，主要用于学习研究。
- 此套系统是基于
debootstrap配合GUN/linux社区版本实现的自动构建系统，主要是一些列脚本等。 - 由于社区版本目前支持的硬件不够完善。接 下来计划支持使用 Tina-sdk 里的 boot0 opensbi uboot kernel 各个组件来自动生成一个完整系统镜像。
1.此构建系统基于 debian类发行版系统，如ubuntu debian mint等，示例使用的是debian 10.
在开始编译前需要先执行 prepare_debian_host.sh 脚本来安装编译所需的各项依赖。
2.安装完成依赖环境后，就可以执行 build.sh 来开始构建基于社区版本的 boot0_spl opensbi uboot kernel等镜像，开始之前还是会自动编译构建一个 GNU GCC工具链。
3.等待编译完成系统所需的各个阶段，就可以使用 setup_rootfs.sh 来生产文件系统镜像了。
4.等待上一步结束后，就可以执行最后一步 output_images.sh 生成一个NezhaSTU-Sdcard.img 镜像，用于生成一个最终镜像，可以直接使用 dd if命令 或者Windows下的 wind32diskimage进行烧写。
5.烧写完成后，插到开发板TF卡槽上，上电就会启动了，等待提示输入用户名和密码。 登录用户名root 密码100ask 登录用户名root 密码100ask 登录用户名root 密码100ask
