Mister fpga on pitop v2

There is a Project Mister FPGA based on the DE nano 10 fpga FPGA development tool

We have the problem that we cannot integrate this project into a Pitop V2.

Look here:

The display HUB of the Pitop V1 is based on the STDP2600 chip and works perfectly with the Mister FPGA Project.

We are desperately trying to integrate the project into the Pitop V2.

However, the display HUB of the Pitop V2 is based on the HDMI to EDP low power conversion chip - NCS8803

look here:

We can’t get the Mister FPGA to output an image on the Display of the PITOP V2.

With other devices such as the Raspberry Pi or simply another source such as another notebook that is connected to this HDMI input brings a picture on the display of the PitopV2 only the MIster FPGA does not bring a picture on this Pitop V2 display.

Our project now stands still because we don’t know what to do next.

We have one last hope that you can help us to initiate the start sequence so that the display starts up even with the Mister FPGA on the Pitop V2.

Can you please have a look if you can help us?

Thank you in advance for your time.
