FYI Minor nit... a simple copy/paste failed... that print of the cmd line
did not include quotes around the -append text:

Cool beans... I've updated.

AFAICT the compile is working... It is running from the command line now... I
expected it to be slow so I have also increased the timeouts last night. So
far it still fails. I did notice that there is a new 'R' in the wait output.
<quote>
.........................R......................... failed (silent)
------------
qemu log:
qemu-system-microblazeel: terminating on signal 15 from pid 3357146 (/bin/bash)
</quote>
I was hoping that meant it found qemu 'running' but looks like that was just a
retry... :-(
Last night I increased some of the timeouts I could find.
<quote>
LOOPTIME=5 # Wait time before checking status
-MAXTIME=150 # Maximum wait time for qemu session to complete
-MAXSTIME=60 # Maximum wait time for qemu session to generate output
+#MAXTIME=150 # Maximum wait time for qemu session to complete
+#MAXSTIME=60 # Maximum wait time for qemu session to generate output
+MAXTIME=300 # Maximum wait time for qemu session to complete
+MAXSTIME=120 # Maximum wait time for qemu session to generate output
</quote>
But thanks to the qemu command line hint I can see these were not nearly
enough... (It has been running for > 20 minutes... and I'm not getting
output...) Or I've done something really wrong. Shouldn't qemu be at least
showing something on the terminal by now? I normally run qemu with different
display options (and my qemu foo is weak) so I'm not sure what I should be
seeing with this command line.
09:06:28 > /home/iweiny/dev/qemu/microblazeel-softmmu/qemu-system-microblazeel
-M petalogix-s3adsp1800 -m 256 -kernel arch/microblaze/boot/linux.bin

none -serial stdio -nographic
Maybe I just have too slow of a machine... :-/
My qemu was built back in March. I'm updating that now...
Sorry for being so dense...
Ira
