build uboot for Beaglebone

hello,

I try to build uboot for debian beaglebone (I follow the site here: https://eewiki.net/display/linuxonarm/BeagleBone#BeagleBone-InstallKernelandRootFileSystem), but it can’t boot the system and always find rootfs from the server, what should i do ? Is there some place that i need to be attention? Thanks a lot.

Victor
