you need to change include/configs/qi_lb60.h
Line: 108 #define QI_LB60_NAND_SIZE  to 1
sinece your board is 1GB nand flash.

the kernel in xiangfu/qi-kernel should work.

1. you can download
reflash again.

2. remove -fno-unit-at-a-time  compile the xbusrt_stage2 again by
    "make CROSS_COMPILE=mipsel-openwrt-linux- clean"
    "make CROSS_COMPILE=mipsel-optnwrt-linux- "

there is no error before or just come up this time?
