How can I update the Arduolane firmware on Navio2

I tried to update the Arduplane firmware from 3.8 to 3.9 on Navio2 through Misson Planner 1.3.58.
But I could not.
Navio2 uses neither com ports nor USB(device side) ports.
How can I update the Arduolane firmware on Navio2.
Please see the attached Error Message.

Thanks to Marc, the problem was solved.
