I doubt that. The examples in the manual are generated automatically
(by running DUTS); it seems to have worked by then.

BTW: Please rstrict your line length to some 70 characters or so.

I don't understand  what  the  flash  mapping  has  to  do  with  the
operation  of  GDB?  As  long  as  all of the U-Boot image is mapped,
everything should be fine. Also, I think  the  provided  config  file
does map 4 MB at 0xFFC00000, doesn't it?
