Firstly, there's no need to send the same message multiple times (twice
within an hour).  This is a volunteer project; you'll get help when folks
have time.

I just built RedBoot for this platform, following the quoted steps.  No
problems encountered.

   % export ECOS_REPOSITORY=/work2/ecos/packages
   % mkdir /tmp/se_test
   % cd se_test
   % ecosconfig new se7751 redboot
   % ecosconfig import ${ECOS_REPOSITORY}/hal/sh/se7751/current/misc/redboot_RAM.ecm
   % ecosconfig tree
   % make

 From the errors you listed above, my guess is that you tried to build
RedBoot in a non-clean directory.  Always start with an empty tree when
you run 'ecosconfig new'

Also, I'd suggest that you get sources that are newer than 2.0 (which
is now approaching 5 years old!).  eCosCentric has snapshots of the
latest CVS tree for those behind firewalls.
