[U-Boot-Users] Loading u-boot

[Ed Okerson]

Thanks to some help from Thomas Lange, I think I am about ready to load
u-boot on my DbAu1500 (Zinfandel) board.  The problem I have now is, how
exactly does one do that?  The board currently has Yamon in the boot flash
at 0xbfc00000, and has secondary flash at 0xbec00000.  The s-records in
u-boot.srec indicate that it wants to load at 0xbfc00000, but that causes
yamon to overwrite itself and crashes.  I have tried changing TEXT_BASE to
0xbec00000, and the s-records then look correct but it still doesn't load.
I then tried changing TEXT_BASE to 0xa0100000 to get the s-records to load
to ram, which appeared to work, I then erased the secondary flash
and copied the ram to flash with:

YAMON> erase bec00000 100000
YAMON> copy a0100000 bec00000 100000

Then flipped the swap flash switch and hit reset, and the system did not
boot.  Can anyone enlighten me on how to do this?

Thanks
