Now I'm trying to set up QEMU so I can debug it (no remote debugging yet!), and am having trouble following the instructions on the website <>. I have QEMU downloaded and running (I get the same shutdown), so I've got a good start. I've launched the gdbserver oh QEMU, but I can't connect to it from gdb (through the Cygwin environment). I get the error:

Which QEMU executable did you download ?

Are the cygwin tools the latest built by the RSB ?

It looks like the versions of tools are not compatible.
