I'm trying to get the signals coming from a external camera sensor.The sensor signals are pretty standard and they look like that:
Well before to do any real hardware test I wrote a testbench generating a the sensor signals and simulating the core "Video in to Axi4-Stream" correct inputs, the results are quite good:
In the simulation I'm only driving:
- FV to vid_vsync
- LV to vid_active_video
- Dout to vid_data
And everything works perfectly.
Well I'm trying to do the same with the real hardware and it doesn't work and I don't get it when the simulation does....
After the previous test I tried to drive the rest of the pins:
But the axi stream still not working.
Any ideas what could be wrong or missing?

-> synthesize the design and do the simulation again on the synthesized design
-> if this is working, add an ILA on the input to see if the inputs of the Video in 2 AXI4 stream Ip are as you expect.
Hope that helps,

Hi @florentw, thanks for your answer,
Sorry I didn't say but the simulation I did was a post-synthesis one and it works fine....
I already checked the video input and they look ok.
Any more ideas?

Check the overflow and underflow signals of the IP. It could give an information.
