I have a Nexys A7-100T board. I want to supply voltage using external battery pack for my measurement.
But for my measurement setting,voltage supply line has 6.5Ω resistance.When I supplied 5 V to voltage supply line, FPGA coundn 't activated.
I guessed the reason for activation problem is voltage drop. I supplied about 7.25 voltage so that voltage between battery’s positive terminal to the center pin of JP3 and the negative terminal to the pin labeled J12 is about 5 voltage.I checked the center pin of JP3 and the pin of J12 is about 5V. But I coundn 't activated.

Why coundn 't I activate Nexys A7-100T?
