I've compiled Linux kernel 2.6.16 with kgdb on Linux. And after that, I've tried to debug this kernel with Qemu 0.8.1 on Msys to simulate ARM Processor. In fact, I've run the command below:
qemu-system-arm -kernel myKernel -initrd arm_root.img -s
But I can't make the connection from arm-toolchain-gdb to the port 1234 (by default, this port must be openned by Qemu when using the option -s for debugging)
Furthermore, I've confirmed if the port 1234 is openned or not with the command: netstat -ao and there is not port 1234 openned. I've also try the option -p 123456 to change the default port for debugging of Qemu but I've got the same result.
Do you know where the problem arrive?
Thank you so much for your support.
Best regards.

Sneak preview the all-new Yahoo.com. It's not radically different. Just radically better.
