Arria 10 SoC Dev Kit FPGA side GPIO

Hi,

I want to know if there is any GPIO on the Arria10 SoC Dev Kit's FPGA side. Or any pin that can be used as GPIO purpuses. I want to communicate with pc and as I understand all UART ports connected to HPS side and I don't know anything about HPS side and don't want to deal with that stuff for just a simple UART. If there is any 2 pins that can be used freely I can communicate with pc. May be jtag pins or even ethernet ports can be used?

    Think of the SoC as two devices. If you're more familiar with FPGA design, you can use the device as an FPGA without even thinking about the HPS side. So, yes, you can make FPGA I/O pin assignments just like any other FPGA.

      I know how to connect pins but there is no GPIO or UART pins to connect in FPGA. There is a DB9 UART connector on device, in the device documents shown that, it is UART1 but there is more than one UART1 pins in the schematics and I cannot understand which one belongs to which UART port. I tried all of them but cannot receive or transmit data. Because of this I am asking if there is any other GPIO like pins for can be used in UART communication. And again Intel sells $3500 worth board and they didn't even properly documented it and not putting any GPIOs is unbelievable.
