大家好，如题所示，clone github最新openwrt18版本编译产生bit5固件，烧写后无法挂载文件系统，log如下：

在下做了如下修改：
1、复制/dts/WIDORA-NEO-32M.dts为/dts/WIDORA-BIT5-32M.dts
并修改内存大小为reg<0x0,0x40000000>
/ {
compatible = "widora,bit5-32m", "widora,bit5", "mediatek,mt7628an-soc";
model = "Widora-BIT5 (32M)";
memory@0 {
device_type = "memory";
reg = <0x0 0x4000000>;
};
};
增加板卡信息到02-network和mt76x8.mk，然后进入menuconfig后选择bit5并编译产生固件，
固件大小为8.1M
通过widora得网页uboot更新firware。
上传dts。。。
1559495611007-widora-bit5-32m.dts (970 Bytes)
还请各位指点迷津，在此感谢各位！
