However, I did add the peripherals on and now it does not work; so the next step for me is to remove the peripherals and confirm the functionality of the DDR4 without it. Any tips on how to test the RAM functionality would be great. Right now I am just writing, then reading to see if I get the same value. The next thing I was thinking of is writing from HPS, then read it from the FPGA side and loop it back to the HPS using a bridge.
