Won't boot with GPS breakout attached
guess what? rock64 has 3 uarts. i suggest you read this thread. it won't give you the answer but it will point you in the right direction.

a side point is any gps card that will not let you select optional uart connections is cheap. so find out which uart the gps board wants to use and then learn how to get access to another uart. if it is not possible to set up a serial console on an optional uart and your gps card can only use one uart then not sure what you do next.
