Multiple XDMA IPs co-exist in project

Hi everyone,

I want to use two xdma ips in my project. One of the ip is configured as memory mapped and the other one as streaming core. Is it possible to have such configurations in the project?

I created a sample project with two xdma ips (one memory mapped and other stream) on alveo 280 card. After loading the bitstream, the lspci command shows the only the memory mapped core. Also, no activity is observed on the stream xdma core in ILA. I do a dma_from_device transfer but c2h_ready does not go high at all.

I have constrained the two ips on separate GTs and the clock for the two are also different. Please suggest if i have missed anything.

Any help is appreciated

Thanks.

Hi @nupur.ec 

I don't believe XDMA supports streaming, did you see this as a feature somewhere? 

I was under the impression the QDMA IP would need to be used for streaming interfaces.

Thanks for your reply.

The XDMA ip can be configured as streaming core while customization and supports streaming interfaces.
