bash before_install.sh
make clean
make qemu
Use make to build binaries and image files.
make
At this moment tests works by injecting predefined ASM in the source code which halts the execution at the point of interest. After that tests can make use of QEMU monitor to verify the current state with expected state.
make test
Execute QEMU in debug mode and setup GDB server.
make qemu_debug
And then connect to GDB Server.
make qemu_debug_connect
