no, GDB will set the breakpoint on loading. so, if you staid connected, did a reset of the board and then reloaded the image, you'd end up with the breakpoint set again.

what i usually do is set breakpoints at cyg_user_start and cyg_assert_fail before doing the continue.

I've compiled and done everything in link you sent:

when I do the continue it seem to hang waiting for

the

target to connect. When I <cntl-c> out it reports
interupted while waiting for the program
Give up (and stop debugging it?) (y or n)
Am I missing something? Do I need to write a stub

for

my program or is the one in Redboot sufficient?

hmm...not sure whether you did that, but did you set

a breakpoint? at least from the summary above it looks like you

didn't...

Can  you point me to some info and, can I use gdb

in

"exec" mode, since at that point I beleive there

will

no longer be any Redboot support

You don't need to use exec mode. Just connect with
gdb then use gdb to
load the application into ram, set breakpoints and
use gdbs go command
to set it running.
