I'm a complete idiot. I got it to work. I searched online and couldn't find anything for this board into i looked up the name arduino tau and it first page comes up as Tau | Rabid Prototypes It tells you in there how to program it has a modded version of the arduino zero bootloader. it requires there board program to make this board work. It is a arduino zero chip a SamD21 chip.

so i got blink sketch to run.
