Well, IMHO the tools should fit the work, no vice  versa.  Maybe  you
can talk with ETS and ask what's necessary to load a Linux image with
their tools.

I don't use EST right now, so I can't help here. I'm using  the  Aba-
tron  box,  and found that Abatron was *very* helpful many times, for
instance by providing a Linux version of their configuration  utility
within  a  few days after I mentioned that I need something like that
(in fact, when I asked for _some_ documentation for the protocol thay
use to access the box, they sent me the full  source  code  of  their
tool). If your tool vendor is no so helpful, you know the options :-)

I'm probably with you here.

Here Dan is right, I think. Normally I just strip the ELF header  and
use  the  file as "binary" image - all the tools I'm using can accept
that.

Ummm... depends on your definition of "commonly used".

I never needed it myself...

You might also argument that you should be using a firmware which  is
capable of downloading a linux image :-)
