我的编译步骤完成参照晕哥的帖子https://whycan.com/p_63208.html
编译环境：ubuntu-18.04
编译前安装了依赖包如下
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -y make gcc g++ unzip git bc python device-tree-compiler mtd-utils
sudo apt install gcc build-essential bison flex gettext tcl sharutils libncurses-dev zlib1g-dev exuberant-ctags g++ texinfo patch vim libtool bc git python3 unzip python3-distutils swig python-dev
sudo apt install gcc-arm-linux-gnueabihf编译版本：buildroot-2018.08.2 并且使用晕哥帖子里面的backup_20190220A.tgz文件
编译结果：

flash_32m.bin1、直接烧录打包文件
sunxi-fel.exe -p spiflash-write 0 flash_32m.bin
烧写完发现芯片不能启动，上下电后依旧停留在sunxi-fel的烧写模式
2、单独烧录
sunxi-fel.exe -p spiflash-write 0 u-boot-sunxi-with-spl.bin
烧写完后，发现可以进入uboot，日志如下：

sunxi-fel.exe -p spiflash-write 0x100000 sun8i-v3s-licheepi-zero.dtb
sunxi-fel.exe -p spiflash-write 0x110000 zImage2
sunxi-fel.exe -p spiflash-write 0x610000 jffs2.bin
发现烧录到最后jffs2.bin文件的时候，芯片就无法正常启动了，停留在sunxi-fel的烧写模式。
新人第一次入坑，求大佬帮忙看看，谢谢！

感觉是uboot的sun8i.h修改没有成功，或者没有重新编译uboot。
这个文件我没有动过
