Hi

Thanks for your reply.

Yes, my project is based on Qsys system.

I have tried the above steps which you mentioned. From that I understand through "txs" we can access the host memory.

So, I like to know is it "txs" of PCIe is accessing the DDR memory or some other internal memory?.(If you know how to see that, please help in it)

If it is possible for you to share any reference design for the configuration we discussed.

It will help me to access the host DDR memory.
