[Qemu-devel] How to debug QEMU with GDB??

[xdutaotao]

Hi,

I want to debug QEMU, but unfortunately after I set breakpoint in someplace of QEMU, then continue to run, GDB give me the message:

 

“Continuing.

Warning:

Cannot insert breakpoint 1.

Error accessing memory address 0x2dad0: IN/OUT ERROR.”

 

So I have to ask some question here?

1)       How to find bug in QEMU if GDB doesn't work with QEMU?

2)       What did you do when you must test your code of QEMU?

 

Thank you!
