SIGINT handling for rdi target

SIGINT handling for rdi target

[Fabrice Gautier]

Hi,

I'm using a EmbededICE device with an ARM board and I connect using the RDI
target. The problem is that there I can't interrupt the target from gdb.
Looking in the code, I didn't saw any SIGINT handling in remote-rdi.c as
there is remote.c for the serial target.

Does anyone know why? And If this is related to my problem

Thank You

A+

What is your host system?  Linux?  Solaris?  Windows?

How old are your gdb sources?  Are you using the command line interface?

My host is WinNT + Cygwin.

I'm using the Insigth 5.0 release + patch for eCos.
If I use the Insight GUI, pressing the Stop button does nothing (in fact the
whole GUI seems frozen) Typing Ctrl+C in the console window of insight
doesn't help more.

BUT

When launching only the cmd line interface (gdb -nw) ctrl+c works.
AND
With the GUI interface, sending an explicit sigint to the process (kill
-sigint pid) works as it should. With the message RDI_execute: you pressed
Escape.

So it seems this is only a problem with the GUI.

Thanks

A+

I've run into this also.  I can do a "kill -INT" on the gdb
process.  This stops the remote, and then the Insight GUI pops
up a dialog box complaining about getting a signal.  When I
acknowlege the dialog box, the GUI then just locks up.

Anybody figure out how to get this to work?
