The probe scripts, run.sh, trace_run.sh, webui.py and two emulator tests each named the same hardcoded firmware from a source tree that is not in this repository. They now resolve QEMU and the firmware the way tools/uvk5_testenv.py does -- environment, then PATH, then whatever the checkout has -- and skip with a reason when there is nothing. webui.py's --qemu and --elf lost their author defaults too: a bare qemu-system-arm through PATH, and no firmware until one is uploaded, which the page already reports.
