Via is there for a reason so its connected to somewhere
if you cant see a trace from other side of the via then the trace will be in side the pcb (multilayer pcb)

hense why we say cut trace and wire a switch in place instead of lifting pin 55 (easier to do)

If it is not connected to GND like in another Carprog(is not ,I checked the multimeter)
That's where it's connected?
it is only for reset the processor

I checked with multimeter, and that pin I circled is not connected to ground, or anything else that I could find.

I checked against the ground from DB25, and ground from various points around the board, including the mini USB direct ground.

I will try using the hole to solder for Atmel erase, without lifting or cutting. Hope it works.
