Hello, I am interested at this project. I am using ZCU104 board and I have tried this instructions. It is successful for a video but when I tried for two video, I get an error. I think, I get this error because I do not have enough bandwidth. To expand bandwidth, I need to use PL DDR. I bought to external DDR4 memory and I have designed my project with VCU DDR4 Controller but I did not activate PL DDR4. How can I activate PL DDR and how can I understad whether DDR is working. I am in the begining level in this branch, can you help me?

Do you have any update on this? Were you able to enable the PL DDR?

No, unfortunately I haven't enabled PL DDR yet. I am trying to test my PL DDR. I installed the DDR4 SODIMM in PL side and I have tested my board with Built-In Self-Test (BIST). I got an failure in my test. What is this due to? There is a datasheet about SODIMM ,which I used in below. Can you help me to solve this problem.

Well it seems that there is an issue with your SODIMM or your PCB. This is not my epertize. You might want to create a new topic on the memory interface board
