I have installed Vivado and programmed kcu105_uhdsdi_demo bit file. I have connected scope to TX0 on Fidu FMC card and cannot see any transmitted signal. I have changed data rates or played with reset bits, using hw_vios, but still i have the same problem. I would appreciate if i can talk to someone so we can quickly resolve this issue. I think this is something on my setup. Here is my phone number: 1-669-721-5109.
