The gdb and insight mailing lists are probably the best places
to get help on gdb and insight.  Most of the gdb/insight
experts don't read the eCos mailing list.

I've used Insight 5.0 with the Jeeni under Windows and Linux,
I've never tried the Wiggler.

You should be able to type the same commands into the gdb
window when using the windowing interface.  Does that work?

I have gotten Insight to connect using the menu/dialog-box
method, but I find it far simpler to type "target" and "load"
commands in the gdb window.

If you get that method to work, and you still want to use the
menu entries, let me know, and I'll go back and find my notes.

When you run the no-windowing version, can you stop execution
by typing "ctrl-C" under Linux?  [I don't remember if ctrl-C
works under Cygwin.]

In order to get the "stop" button to work with the Jeeni, you
need to either use a CVS snapshot of gdb/insight or apply the
patches at
