Atsame70-xplained board bootloader

Hi Guys,

Is there any completed bootloader can be downloaded to the ATSAME70-XPlained board?

I see the source has done Same70-Xplained this board compatible, but I did not find the corresponding bootloader.

Have you completed bootloader function on Atsame70-xplained board?
I am developing bootloader on samv71-xplained board.
