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. Oh, and please update the repository; turns out I didn't push for a while and made a number of changes. My compiler was compiled with buildroot (a long time ago). I don't recall if it needed something special in the configuration, unfortunately.
