The receive errors are listed here...
The one of interest is...
fault_timeout_knock = 0x11
The receiver (your Uno) is expecting a low pulse of a certain duration (a "knock"). The pulse is too short to be a knock.
The problem could be caused by the target running at 1 MHz with code built for a processor running at 8 MHz. Which "board" do you have selected? Have you used "burn bootloader" to change the fuses?
