All,

Reading through your message, the one thing I notice is:

> Number of SMP cpus requested (2), exceeds max cpus supported by machine `xilinx-zynq-a9' (1)

You seem to think this is an RTEMS message, whereas I think this is a
qemu message.

I hope that is of help.

Cheers,
Ben

> I verified as per the "SMP support for Raspberry Pi 2” thread that —enable-smp was really set during configure, the cpuopts.h files have "#define RTEMS_SMP 1”, and ZYNQ_CPUS = 2 in $DEV_ROOT/rtems/bld/a9_qemu/arm-rtems4.11/c/xilinx_zynq_a9_qemu/lib/libbsp/arm/xilinx-zynq/Makefile and config.status.  ticker.exe runs and smp01.exe produces no output in QEMU, when I leave the -smp parameter off.  What is the status of the ZYNQ BSPs?  Is the 2nd core nominally started, or is that something I need to work on?  Why is QEMU thinking there is only one core configured?
