That's because you've only downloaded the code to your target board. You
haven't given GDB/Insight an executable to work on. I presume that
"eCos.elf" was generated by a compiler. I suggest you change your
startup script to do:

file eCos.elf
target remote localhost:2345
load

instead of the last two lines you have. The "file" command is the
equivalent of Insight's "open": it causes GDB to read in debugging
information for your executable.

That's because the "open" command does the equivalent of GDB's "file"
command (the step you were missing before).

It prints the error for one of two reasons: you haven't selected a
target to debug (File->Target Settings..." or it isn't setting the
target based on the last run (which is a bug).
