Total. They're two tools serving almost completely different
purposes.

But how can ecos run without redboot bootstrap?

Maybe it can't. That depends on the hardware. Some hardware may be
able to boot eCos images kept in just the right storage, without the
need for a boot utility. Other hardware needs redboot or something
like to load the eCos from some place and run it.

To maybe put it into a more familiar context, think of redboot as your
BIOS, and eCos as something like MS-DOS, to be loaded off the disk or
floppy by the BIOS.
