U-Boot 'saveenv' command overwriting U-Boot?

Hello All,


I am running into a problem with u-boot (I'm using u-boot 2011.06).  Every time I issue the 'saveenv' command to write my updated u-boot environment to flash (microSD), u-boot fails to load/start when I reset/power cycle the board.  It's as though the 'saveenv' command is overwriting the u-boot in flash.  I end up having to 'dd' the u-boot image back on the microSD card to get u-boot to start up again (losing my previous u-boot environment of course).  Has anyone else encountered this problem with u-boot?  If so, what do I need to do to resolve this issue?  I'm pulling my hair out trying to find a solution.
