This extension allows running programs in QEMU similar to running them on a real chip: - 'idf.py qemu' — builds and runs the program in QEMU. User gets a QEMU instance launched, and can work with it as a normal QEMU instance. - 'idf.py qemu monitor' — same, but QEMU is launched in the background, and idf_monitor runs in the foreground, showing QEMU output. Compared to only running 'idf.py qemu' this enables, for example, automatic backtrace decoding. - 'idf.py qemu gdb' — launches QEMU in the background and opens an interactive GDB prompt, connecting it to QEMU. - 'idf.py qemu --gdb monitor' and 'idf.py gdb' in another shell: launches QEMU in the background, keeps it suspended until GDB is connected, and opens idf_monitor. GDB can be used in another shell to debug the application.
