按log初步分析判断是调用/etc/preinit找到不系统初始化文件 /sbin/init
具体原因还没分析出来。
已经把此问题发在openwr官方论坛：I had a problem when openwrt(chaos_calmer) was running no MT7628 board - For Developers - OpenWrt Forum
官方也没给出好的愿意付出，只是openwrt(chaos_calmer 15.05) 不再维护与支持，需用新版本
后面我们在ubuntu16下重新搭环境，编译通过后，就能在开发板运行了
我们的荣誉不是在于永远成功，而是在于失败和绝望时能找到重新站起来的希望，勇敢的面对困难战胜困难。
