在编译完成后，输入人pack打包生成镜像时，出现错误信息ERROR: Dependence broken. Firmware maybe incorrect & cannot booting up…
此时打包生成的镜像会无法正常启动，会出现重复进入烧写模式等异常情况
book@100ask:~/workspaces/tina-v853-open$ pack
/home/book/workspaces/tina-v853-open/build/pack -c sun8iw21p1 -i v853 -p openwrt -b 100ask -k linux-4.9 -d uart0 -v none -m normal -w none -n default

解决办法：
删除out目录：
book@100ask:~/workspaces/tina-v853-open$ rm out/ -rf
重新构建编译环境
book@100ask:~/workspaces/tina-v853-open$ source build/envsetup.sh
...
book@100ask:~/workspaces/tina-v853-open$ lunch
...
book@100ask:~/workspaces/tina-v853-open$ make -j32
重新编译完成后再打包生成镜像即可解决。
