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 GPIOhttps://documentation.altera.com/#/00045071-AA$AA00044989 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.
