Hi, I'm looking for a startup code (entry.S start.S or similar files) that can be load using uboot. I tried to adapt start.S from uboot but without success. I can't locate source of my problem. If you suggest me a simple bare metal project loaded by uboot for mini2440 I'll be gratefull. Existing 2440test is can be boot only using SuperVivi. Regards Jacek
