Ctrl-C does not work

Ctrl-C does not work

[Marko Mlinar]

Hello !

I am just finishing gdb port for or1k cpu. I've noticed that ctrl-c during
program execution does not
interrupt the target (I suppose this should occur during execution of
or1k_target_wait() function).
How can I turn this on?

thanks,
    Marko

A little bit more information is probably needed.  How exactly is GDB 
connected to the target?

More or less guessing what you are doing, I believe you forgot to
set the signal handles for SIGINT to some function of yours that
calls your or1k_target_stop().  Assuming that you have a
or1k_target_stop() and that it works (and your target can be stopped). 

Don't forget to save the old handler and restore it.  You may want
to have a second handler for the case the target does not stop and
you want to close (abandon) the connection.  Look at remote.c for 
some inspiration.
