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.

"""Firmware serial output must reach the host.
|
|
|
|
App/main.c sends UART_Version over USART1 right after UART_Init(), and _putchar
|
|
routes every printf_ there too. The machine has no USART1 model -- it is one of the
|
|
logging catch-all stubs -- so without help those bytes vanish and the firmware
|
|
appears to print nothing at all.
|
|
|
|
Boots a real emulator on a private socket and checks the bytes come out of QEMU's
|
|
stderr as SERIAL lines.

Run: python3 tools/test_serial_capture.py
