[U-Boot-Users] Need help booting an unsupported OS on ARM

I am trying to use U-Boot to start up a home grown OS. How can I make my OS a little more U-Boot friendly, or visa-versa? The specific problem I'm having is that when I issue a SWI on the arm, the U-Boot interrupt routines get used instead of mine.

I can see why that is happening because the vectors in the flash address point to the U-Boot routines, but I'm wondering if there is a way to set a secondary jump so that my routines are used.

Thanks,
