One little question: is insight in your ecos executable? What happens
when you omit the "-nw" parameter? ("nw" == "n"o "w"indows, aka, no
Insight)

I just sent you a note about how to rebuild the snapshot based on your
target. When you use just "./configure", you are implicitly telling the
sources to rebuild themselves for your host (linux). You want to add the
"--target=arm-elf" flag to configure to tell the sources that you want
an arm-elf debugger running on linux.

Probably your eCos gdb (which may not have Insight in it).

Yes, this is your native gdb that came with RedHat 6.1. It is installed
in /usr/bin. It does not contain Insight.

The one you just built from the snapshot.

Right: you built a linux debugger, not an arm-elf debugger which runs on
linux hosts.

Cygnus (now RedHat) has a URL which describes the procedure:
