MKR Vidor 4000 help

[danielmahal]

I'm trying to get the hdmi-demo running on my Arduino MKR Vidor 4000 with Intel Cyclone 10 LP (10CL016).

What I've done so far (with some assistance from Claude)

1. Set up the project:

   • Cloned the repo
   • Installed dependencies (quartus, hdlmake, six)
   • Navigated to syn/mkrvidor4000_quartus

2. Built the FPGA bitstream:

   • Ran hdlmake and make (both completed without errors)
   • Converted to .rbf: quartus_cpf -c hdmi-demo.sof hdmi-demo.rbf
   • Moved hdmi-demo.rbf to data/MKRVIDOR4000.rbf

3. Arduino setup:

   • Created basic sketch (just FPGA init + serial debug)
   • Uploaded via Arduino IDE
   • Sketch runs and outputs to serial as expected

The issue

No display output, despite trying with:

• Blackmagic Video Assist 7 12G
• Standard HDMI PC monitor

Questions

I'm wondering if:

1. FPGA-specific setup:

   • Do I need to customize this for my specific FPGA?
   • Could there be differences in pins/PLLs?

2. Power requirements:

   • Currently using USB power (both from PC and robust supply)
   • Any special power needs?

3. Cable compatibility:

   • Using new micro-to-standard HDMI cable
   • Any specific cable requirements?

I'm new to FPGA development, so apologies if I'm missing something obvious! No pressure if you're busy – any pointers for troubleshooting would be super helpful though.

Thanks for publishing this @sameer – it's really inspiring stuff! 🙏

That all sounds right to me. Have you tried with another monitor/TV?

Okay, thanks. Strange… I did test with a Blackmagic Video Assist 7 12G, and a standard Dell PC monitor. Could try a third, just to be certain there's some incompatibility issue…
