Sorry for the false alarm, but I found out why it did not work.
My leon3 BSP configure command had –enable-smp
Once I removed that, it worked on both QEMU and TSIM-LEON3.
At least on Qemu it used to work with SMP enabled some time ago. With
the latest Qemu the BSP starts (with SMP enabled), but the timecounter
seems not to work:
qemu-system-sparc -no-reboot -nographic -M leon3_generic -m 64M -kernel

The ut699 BSP worked as well.
Does an SMP enabled kernel/bsp only work on a system where there are >
1 cores?
A SMP enabled BSP should work also on systems with only one processor
provided you use the right instruction set. I use for example the erc32
BSP with SMP enabled all the time for RTEMS development.
Thanks,
Alan

*Subject: *sparc/leon3 in git master?
I use RTEMS 4.11 on several leon3 targets, and I have been starting to
work with the git master to get ready for RTEMS 5.
With 4.11, I can run ticker, hello, and other samples on TSIM2-LEON3,
QEMU with Jiri’s leon3 patches, or real Leon3 targets.
When I run the ticker or hello for RTEMS 5 (RSB toolchain and RTEMS
built today) on QEMU or TSIM2 they immediately return with no output.
I tried ticker for the sparc/erc32 BSP on SIS and it works.
Before I start debugging, has anyone else used the generic Leon3
target on RTEMS 5 lately?
Thanks,
Alan
