Yes, U-boot supports chain loading. On host machine you can use ckermit[1] program to load U-boot image using serial or you can use tftp to load modified U-boot image at SYS_TEXT_BASE address. Once the image is loaded , you can bootm "SYS_TEXT_BASE". Thanks -Amit [1]: http://blog.mezeske.com/?p=483
