I would like to get the Arria V DK-START-5AGXB3N starter board to communicate with another FPGA through I2C module that I've created (verilog), but I don't know how the GPIO pins are wired internally. The pin planner of Quartus software doesn't show which pins are which.
I've done this using Cyclone 10 before and I was lucky to find a board block diagram which maps the GPIO to the pin number of the FPGA chip. With the Arria V GX (5AGXFB3H4F35C5N), I could not find anything online or from the documentation kits.
The kit comes with HSMC debug header but I don't know if this can be used as GPIO and if so, how is it mapped to the FPGA pins?
Maybe I have missed something here, can somebody point me to the right direction?
Edit: I realized the pin connections to the FPGA are found in the schematic, but I still don't know which ones are available for users.
