<p>Indeed. Qemu git head now includes leon3
plug&play and should be able to run RTEMS images
unpatched. Is there a reason why the qemu version

<p>Unfortunately, qemu HEAD cannot execute RTEMS leon3 images
unpatched. The startup code needs a (simple) tweak, and the
implementation of the plug&play is not quite correct. An RTEMS
binary fails to detect the interrupt controller and subsequently
terminates. I have spent a few hours on it but the bug is rather
elusive and I am not sure I will be able to track it down.
Debugging low-level target code on qemu is not exactly user
friendly :-) ...<br>

Not that I am aware of. The checksum probably
changed because the original patches were lost
during a server rehost, and I recovered some
earlier version from a backup disk. The
patches do not apply cleanly to the latest
version of qemu:<br>

Could be that qemu has moved since the patches
were make, I will try to take a look ...<br>
