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 :-) ... > > Jiri. > >> >> Regards, >> Juan. >> >> On Fri, Aug 16, 2019, 11:00 PM Jiri Gaisler <j...@gaisler.se >> <mailto:j...@gaisler.se>> wrote: >> >> >> On 8/15/19 12:09 AM, Joel Sherrill wrote: >> > On Wed, Aug 14, 2019 at 4:42 PM Chris Johns >> <chr...@rtems.org <mailto:chr...@rtems.org>> wrote: >> >> On 15/8/19 12:46 am, Joel Sherrill wrote: >> >>> Qemu isn't building due to a checksum error. >> >>> >> >>> These patches are at gaisler.org <http://gaisler.org>.
