fpga startup problem

Good afternoon, members of the forum.

I have stratix V.

I have such a problem.

I write down the firmware in the epcq through the AS. The process is normal. In the firmware, I activate one of the LEDs on the board

Starting the card, nothing happens. Then he began to notice that the LED all the same blinks once during the start. In this case, if I change the firmware to another LED, the other LED will blink at the start. That is, the FPGA begins to be configured. And then nothing happens.

I checked the status pins with the voltmeter.

CONF_DONE = 0.1V (is low signal?)

nStatus smoothly changes 0.7V - 1.3V = low signal.

According to the documentation, this is similar to "Configuration Error Handling".

True today, I inserted a card in the pci-e, and my LEDs stopped blinking at the start, according to my firmware.

CONF_DONE = 0.1V (is low signal?)

nStatus = 0V

nCe = 0V

nConfig = 3V

Сontrol outputs on the board (just in case):

3.3V = 3.4V

3V = 3V

2.5V = 2.5V

VTT = 0.38V

VCCINT = 0.9V

VCCIO = 2.59V

Would I be happy with any advice, what kind of problem is this? Where to start searching.

Thank you in advance

ps.
