This document will introduce what you need to pay attention to when the Terasic F2G card is connected to Intel Arria® 10 GX FPGA Development Kit.

GPIO Uisng Status

Due the two FMC connectors FMCA and FMCB on the Arria® 10 GX FPGA Development Kit belong to the low pin count(LPC) FMC type(Note), after connecting the F2G card, only the two connectors GPIO 0 and GPIO 1 on the F2G card can be used on the kit, and the other two GPIO connectors are defined Connected to high pin count(HPC) FMC pin, so it cannot be used in the kit. In addition, the D8/D9 pin on GPIO 1 belongs to the HPC FMC type, so it cannot be used.

On the Kit board, some FPGA I/Os connected to the F2G GPIO connector will have termination resistors(for differential protocol). It is recommended to remove these resistors, otherwise the pins of the GPIO connector will interfere with each other when using in single-end state. Please remove R383,R369 and R336 on the Arria® 10 GX FPGA Development Kit.
