BIT5 下载最新openwrt18固件无法挂在文件系统

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。。。
WIDORA-BIT5-32M.dts
还请各位指点迷津，在此感谢各位！

这样，你clone下来后直接选择NEO，将NEO的DTS里内存修改为64M后编译试一下。
1806之前在NEO上正常。

已解决，配置设置错误导致
