Raspberry Pi 5 CRTP through uart doesn't work

[knmcguire]

So we have instructions of how to connect a crazyflie through uart with a raspberry pi: https://www.bitcraze.io/documentation/repository/crazyflie-lib-python/master/development/uart_communication/

These instructions don't work for Raspberry pi 5 anymore as they handle their uarts differently: https://www.raspberrypi.com/documentation/computers/configuration.html#configuring-uarts

So these are some differences (see above rasppi doc)

• /boot/config.txt is now in /boot/firmware/config.txt
• dtoverlay=miniuart-bt now needs to be dtparam=krnbt=off

This will make serial communication work for simple examples (like this experimental bolt app uart example here with python script), but with the crtp over uart example I get this:

Exception: Couldn't load link driver for /ttyAMA0

This is because the python package pyserial can use the serial port, but if you list it with python3 -m serial.tools.list_ports -v, then only ttyACM10 is shown. This is the port that is not on the standard GPIO 14 and 15 pins, but on a separate debug port on the other side of the board which requires a special plug.
