Test if ARM / xilinx_zynq_a9_qemu built correctly?

Hi Christian,
Thank you for your response, it is much appreciated. The ticker.exe program
works in qemu now: I had to change to a different version of qemu and
switch the order of the '-serial mon:stdio -serial /dev/null' arguments (as
well as use the -S option correctly!).
The details:
The qemu version suggested
by $RTEMS_DIR/rtems-src/c/src/lib/libbsp/arm/xilinx-zynq/README is 1.4.50.
When run with 'qemu-system-arm -s -no-reboot -serial null -serial mon:stdio
-net none -nographic -M xilinx-zynq-a9 -m 256M -kernel ticker.exe' the
output is:
*** BEGIN OF TEST CLOCK TICK ***
TA1 - rtems_clock_get_tod - 09:00:00 12/31/1988
TA2 - rtems_clock_get_tod - 09:00:00 12/31/1988
TA3 - rtems_clock_get_tod - 09:00:00 12/31/1988
At this point qemu freezes. A gdb backtrace shows:
(gdb) target remote 127.0.0.1:1234

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
Updating to version 2.0.0 of qemu appears to fix the issue, with ticker.exe
completing successfully.
So maybe the xilinx/README file should be updated? I don't know why it
specified that version of qemu or that ordering for the serial arguments.
Thanks for the help,
James
