What can i do next?

heng.dong@163.com

continue,

it seems that i should modify the mtd part info when compiling the kernel, according to the mtd info in U-boot. but I don't know where to find it.

openwrt-ar71xx-generic-db120-squashfs-sysupgrade.bin should be the right one.

well, i found the 2 files:  kernel.bin and rootfs-jffs2.bin together work with my AP! unfortunately, my network doesn't work.

so there comes another puzzle:  if only i configure the interface by editing the /etc/config/network, and when I restart, the uboot prints:

bad magic number, and there is nothing i can do but to re-download the 2 bins again and again!  it's that magic number is related to md5sums,

Any thing I can do to let it ignore the magic number?
