Hi Joe Without seeing the sources, I can't really say too much more, but I can tell you in principle that you're making this way too hard if all you're trying = to do is update Redboot. Freescale tends to do their own versions of Redboot, and (no offense Freescale folks) they aren't the cleanest ports. I don't really have cycles to dig through their tree right now unfortunatel= y. You may consider talking to eCosCentric if you want a supported port to the iMX31. --Chris=20
