These error messages are memory-related: The Rockchip miniloader prints "data training error" when it's unable to configure the SDRAM controller to match the type of memory it detected, and "ERR" when it's unable even to determine which type of memory is installed.
I'd say most likely the memory chip on your ROCK64 has died.
