Re: Ctrl-c problem


I tried echoing '\003' and I still can't stop it.

I'm wondering if the problem doesn't come when the boot resumed. After the boot procedure is completed, is there a chance that the serial port used on the target machine be re-configured to a different baud rate?

Then it should work if you are using any current KGDB patch. You can
try echoing '\003' out the serial port (echo '\003' > /dev/ttyS0) and
see if that stops it.

My target platform is a x86 single board computer running a PentiumMMX @ 266 MHz.
Its seen as a standard PC with extra hardware on it (analog to digital converter).

Hi,

I'm doing kernel debugging through the use of gdb running on a development machine and a gdb stub running on a target machine. The latter is acheive with the kgdb patch applied to a kernel 2.4.18. This patch allows me to connect a development PC to a target PC through a serial line. It allows me to remotely debug a patched kernel. The connection works fine, I'm able to connect gdb to the target machine at boot time (target remote /dev/tyS0). The problem is not hardware. I am able to step in the kernel code at this time. After a few step, I resume the execution of the kernel with the continue command.

My problem comes when I want to stop the execution of the target kernel with gdb. Usually Ctrl-c is used to stop the execution of the running process. So I hit Ctrl-c but the kernel never stop.

Is there any configuration for gdb to enable Ctrl-c?

Does anyone ever experience this problem?


What's your target platform? C-c works using the x86 KGDB stub. I
don't know if it works on PowerPC, and it definitely doesn't work on
MIPS. This is a stub question.
