SOS ! Raspberry PI - HDMI - TMDS Hamsterwork HDMI INPUT = not work ?

Hello, I use Mike Fields vhdl code for hdmi processing. from Hamsterwork website. I want to Raspberry PI HDMI output connect to FPGA INPUT.

I try 720p,1080p, progressive, interlaced and any kind of settings HDMI,DVI, component, RGB but result is nothing. I generate TMDS output from other fpga board and connect to HDMI input from other FPGA board and it works.. but Raspberry Pi don't want .

Pls explain what problem ?

DVI-D what Mike Fiel doing not a normal DVI-D ?

Any help appreciated, I spend one week for this :( ..

I can connect to to fpga by I2C and get EDID ROM and parse it : pi@raspberrypi:~ $ edidparser asdf.dat Enabling fuzzy format match... Parsing asdf.dat...

I checked with Oscilloscope on hdmi port on RPI3b, difference between working monitor and fpga board,everything except TMDS channels are same, only TMDS channels are down.
