You can build your new u-boot loader with RAM version. Then you can download it into your RAM and run it.
Yes. You can also nail a piano to your knee.
Neither is a good idea, though.
Especially, the "RAM version" is significantly different fromn the image the original poster wanted to test. So it is just a wasste of time, as the trest of the most critical part (the RAM init sequence) is still missing.
Please read the FAQ. Both befroe asking, and before answering questions. Thanks.
I read the FAQ. I still do not think a RAM version u-boot is just "waste of time". It depends. If we only want to improve some part of the u-boot, such as "PCI", a RAM version might be useful. It is more convenience and cheaper. Finally, we should program the image to flash to verify it. For the original poster, a ram version u-boot is one choice. He can backup his flash image to a file with CodeWarrior + PowerTAP(BDI2000) before programming his new flash image. I hope my comments do not lead to a wrong direction... Roy
