Try running it with "-d" parameter (run-qemu-microblazeel.sh > -d petalogix-s3adsp1800); that gives you the qemu command line. Once it says > "running", abort the script and execute qemu directly. FYI Minor nit... a simple copy/paste failed... that print of the cmd line did not include quotes around the -append text: 09:06:03 > /home/iweiny/dev/qemu/microblazeel-softmmu/qemu-system-microblazeel -M petalogix-s3adsp1800 -m 256 -kernel arch/microblaze/boot/linux.bin -no-reboot -initrd /tmp/buildbot-cache/microblazeel/rootfs.cpio -append panic=-1 slub_debug=FZPUA rdinit=/sbin/init console=ttyUL0,115200 -monitor none -serial stdio -nographic qemu-system-microblazeel: slub_debug=FZPUA: Could not open 'slub_debug=FZPUA': No such file or directory > Oh, and please update > the repository; turns out I didn't push for a while and made a number of > changes.

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 -no-reboot -initrd /tmp/buildbot-cache/microblazeel/rootfs.cpio -append "panic=-1 slub_debug=FZPUA rdinit=/sbin/init console=ttyUL0,115200" -monitor none -serial stdio -nographic Maybe I just have too slow of a machine... :-/ My qemu was built back in March.
