AXI interface issue #16

Open davidfhorowitz opened 1 year ago

davidfhorowitz commented 1 year ago

I'm having an issue sending data to the encoder via axi stream interface. If nothing is connected to the axi stream interface of the encoder, it sends out data. If I connect an axi stream to feed it data, the encoder doesn't send anything out and the axi stream is not active. I can share my design with you if you have somewhere I can upload the zipped vivado project.

Greetings David,

Thank you so much for the report.

We will talk about this at today's FPGA standup and I'll do all I can to help resolve the issue and get things working.

Hi, are working on simulation on a actual card?

If data is coming out without any data being sent, it's likely that dummy frames generation have been enabled (this is disabled by default).

Re the case where the input AXI stream is connected, which frame configuration are you using? Some configurations require the entire frame to go in before any data comes out.
