Did you tie the pins of those peripherals together? You can't just send a message to a serial port and expect something to happen. Rx1 needs to be tied to tx2, etc.
Also you need to config-pin the correct pins to the correct modes, or do it in the device tree. Not sure what you were expecting to happen.
