LRDIMM DDR4 Failure to write was encountered on Arria10 FPGA. Please share your ideas.

Hi, I work as a hardware designer. In my design, I used an Arria10 FPGA and an LRDIMM DDR4 module. I connected an FPGA to a processor using PCIe x8. The procedure is as follows: the FPGA receives c...

Hi!


Thank you for your update.


Can you share some snapshots of the failing issue?

Regards,

Adzim

    Hi,

    Our FPGA team did an exercise, Reading and writing to DDR4 from FPGA for 8GB without DMA access, this part is working. So I suggested doing 64GB and 128GB data read and write. The 64GB and 128GB is read and write is working as expected.

    Could you pl let me know what all screen shot required?
