You can download the arm-elf binaries from
http://www.ariusdsp.com/~gnuarm/files.html

or any other source.

Invoke insight (arm-elf-gdb should invoke insight
debugger or \ufffdarm-elf-gdb \ufffdw\ufffd):
$ arm-elf-insight Your_image.elf

Choose ARM/ethernet target & give the IP of the JTAG
OCD box. You can do a connect & set break point at the
target debug location & reset the board, it should run
& break at the location if it ever hits.

[ FYI: you cannot exceed more than 2 break points when
debugging flash area, since the debugger can only make
use of the hardware breakpoints ]

You don't need GDB stubs on your target hardware for
debugging through JTAG interface. I guess the target
option ARM/ethernet talks to the JTAG interface using
Angel debug protocol. I used JEENI & it worked fine
for me (except when it encountered a \ufffdbx\ufffd, stepi or
nexti acts like continue).

Cheers,
-Mike.
