Re: [Qemu-devel] Ask for debugging linux kernel with Qemu 0.8.1 on Msys

[Tieu Ma Dau]

I recently try the patch you recommend but I got the same result. In  fact, after make this patch into Qemu source code 0.8.1, I compiled it  with these commands:
  ./configure --prefix=/travail/install/qemu-8.1
  make install
  And I run Qemu to simulate ARM on debugging mode:
  ./qemu-system-arm -kernel myKernel-with-kgdb -initrd arm_root.img -s
  And I tried to connect to Qemu by default port 1234: (gdb) target remote localhost:1234
  But I got the error: connection refused
  So I test the current openned port in localhost by the command: netstat
 -ao
  And the result I got is below:
