Programming mistake

Hi, I compiled a project for 5M80ZT100 (100 pin MAX V) in Quartus Prime and loaded it accidentally to 5M80ZE64C5N (64 pin MAX V). After that, I can't reconnect to 5M80ZE64C5N again with my US...

I tried programming with fresh 5M80ZE64C5N soldered on my board. I also created new project in Quartus Prime which consists of simple program:

entity DEMO is

port (

o: out std_logic

);

end DEMO;

architecture b of DEMO is

begin

o <= '1';

end b;

I assigned o port to pin63.

I opened Programmer in Quartus Prime and added .pof file from my demo project to it. I programmed and verified this file with success.

After that current consumption of my board rose from 0.1 to 0.2 A and I'm not able to connect with programmer to 5M80ZE64C5N anymore.

There is nothing connected to pin63 on my board (it is custom board). 1V8 is supplied to core, 3V3 to IO banks. Decoupled by 100n capacitors. What else should I do? Is there any configuration I should do before programming 5M80Z?
