Exactly how did you configure eCos (please explain all the steps)?
For example, I can build RedBoot for the i386/PC using these steps:
% ecosconfig new pc redboot
% ecosconfig import ${ECOS_REPOSITORY}/hal/i386/pc/current/misc/redboot_GRUB.ecm
% ecosconfig tree
% make

Why do you want to rebuild the config tool (an arduous task, even for
the seasoned traveler!)??

You'll need to explain what error you are getting.
