Whether the IO for DDR4 can be used as GPIO?

Question

HI,

Whether the IO for DDR4 in the Arria 10 GX1150 FPGA can be used as GPIO?

I have created one daughter card that using the SODIMM socket on one FPGA board as general purpose io, but it couldn't work.

What should i do?

Regards,

Yong

It looks like the IO for DDR4 can also be assigned as LVCMOS and other applicable IO standard for GPIO

My suggestion is to check the IO bank voltage on the board (for DDR4 it is 1.2V) thus you probably have to use LVCMOS 1.2V as your IO standard.
