IDE's

I'm developing some applications to run on Debian Squeeze, where there
is a module that can only be loaded on the target hardware platform. The
target hardware is not really adequate as a full development platform,
as it doesn't a lot of flash disk space. So far, I have been getting by
without the use of any fancy IDE and using well placed printf's.

But as the number of applications grow and the system takes more shape,
I can see how a good IDE would be nice, but I need one that I can run a
more robust development platform, connecting to the target hardware
platform to debug applications.

Is there such an IDE that can do this without having a lot of overhead
on the target hardware platform?

Thanks!
