Run library examples in sitl

Hi, I just want to know the procedures to run example scripts in sitl. I have done the following steps
./waf configure --board=sitl
./waf build --target examples/AP_Motors_test
./build/sitl/examples/AP_Motors_test -M quad
mavproxy.py --master=tcp:127.0.0.1:5760 --console

Even though mavproxy can able to connect to sitl, I could not able to see the console output. (hal->console->printf)

You don’t usually run the examples in SITL as such. They don’t typically
speak any mavlink, so SITL isn’t relevant.

Running under linux:
