If you set TEXT_BASE to RAM and then try to run it from flash, it will not work. _Maybe_ you can set TEXT_BASE to shadow flash ( xBEC00000 ) and launch it from YAMON. I have not tried this. Be sure to locate the correct entry point if you want to try this. /Thomas Ed Okerson wrote: > Thanks to some help from Thomas Lange, I think I am about ready to load > u-boot on my DbAu1500 (Zinfandel) board.
