环境及编译流程:http://www.dopi.vip/tutorial/markdown/
环境：虚拟机64位ubuntu16.04lts
安装软件包：
sudo apt-get update && sudo apt-get install -y bzip2 build-essential libc6-dev-i386 ia32-libs lib32z1-dev libncurses5 libncurses5-dev u-boot-tools vim squashfs-tools gettext git zip subversion bc这里提示两个问题：
1:
E: 无法获得锁 /var/lib/dpkg/lock-frontend - open (11: 资源暂时不可用)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?解决：
sudo rm /var/lib/dpkg/lock2:
没有可用的软件包 ia32-libs，但是它被其它的软件包引用了。
这可能意味着这个缺失的软件包可能已被废弃，
或者只能在其他发布源中找到
然而下列软件包会取代它：
lib32ncurses5 lib32z1
E: 软件包 ia32-libs 没有可安装候选解决：
sudo apt-get install lib32z1 lib32ncurses5 同时安装(没测试是否必须)：
sudo apt-get install lib32stdc++6安装工具链：
tar zxvf arm-himix100-linux.tgz
cd arm-himix100-linux
sudo ./arm-himix100-linux.install完成后由提示：
export path /opt/hisi-linux/x86-arm/arm-himix100-linux/bin需要使能环境变量：
source /etc/profile然后可以arm-himix100-linux-gcc -v查看版本信息
分别clone uboot、内核和文件系统，按照说明编译
在编译内核时报错:
"mkimage" command not found - U-Boot images will not be built
arch/arm/boot/Makefile:87: recipe for target 'arch/arm/boot/uImage' failed
make[1]: *** [arch/arm/boot/uImage] Error 1
arch/arm/Makefile:334: recipe for target 'uImage' failed
make: *** [uImage] Error 2需要安装工具：
sudo apt-get install u-boot-tools再次编译完成

感谢大佬，昨晚晕哥发给我了就看了，现在才来捧场
新手一枚，感谢版主~

顶一下呀，我昨天也编译成功了，发现根文件系统是编译好的，貌似只是打包一下而已。
是的，就是打包了下，要再研究下编译。
离线
在安装软件包时把ia32-libs这个包去掉，后面就不会出错了，原因是当ia32-libs这个包没有安装时后面的包都没有安装。
不晓得这个会不会用到，能装就装了
离线
拿到板子，一直没顾上测试，把编译好的uboot、kernel、rootfs下载，结果运行不起来，先记录下

fidopi板载是Nand Flash，所以需要输入参数 Nand，执行的也就是在include/configs/dopi.h中写入宏定义，以及./.config中加个配置。
