I think I may have confused you a little. When I said running u-boot from ram, I meant booting it from ram as if it had boot from flash. Normally, at some point, u-boot _will_ run from ram by copying itslef there and continung to run. But getting it to run from ram it's reset vector (first linked address + 0x100) is totally different. I'm not sure what you mean by "running Linux from ram". Although the kernel may reside in flash, it is at some point unzipped, copied to ram and then runs from there. Someone on this list may be able to help you more here. Maybe you will have beteer luck then me getting an answer from these guys. They don't seem to respond to my questions.:-(

Thanks for the idea. I'll check it out. What about running the Linux kernel from ram? Will I encounter the same difficulties? Thanks, Ryan Wilkins On Oct 24, 2004, at 3:33 PM, Frank wrote:quoted
You probably want to post this to the u-boot users mailing lists. Compiling and linking u-boot to run out of ram is notaquoted
straight forward task. I've done it on more then one board,butquoted
it is not easy if you're a u-boot novice. Search the list for "running out of ram" or something likethatquoted
and you'll see what I mean.:-)
