Re: GT2560 V4 Connections for Installing Bootloader

THE PROBLEM is that many of the A20T's were shipped without a bootloader, so you can't flash the firmware AT ALL. I'm asking specifically about how to connect a Ardunio Nano board to the Gt2560 V4 Board to use the Nano as a programmer, so that I can install a boot loader. Can someone share the prope...

Thanks

Leigh.
