Seeing as there's no built in simulator that I could see, I've followed the debugging information on this site and have QEMU built and working. However, I only seem to be able to debug to breakpoints - if i continue or "step" then execution continues until the next breakpoint rather than stepping correctly.
The only changes I've made to QEMU (0.12.13) are to run the socket as Ip4 rather than Ip6.
Is this caused by something in the kernel that it should be stepping up or is it solely an error in my QEMU build?
Below is the change I made to QEMU:
