FMC-HDMI ADV7611 Setting

[sangjin97]

Hi guys~!

I want to use Xilinx Zynq706 board and Digilent FMC-HDMI board.

my ADV7611 setting value is like that,

0x98,0xF4,0x80  // CEC
0x98,0xF5,0x7C  // INFOFRAME
0x98,0xF8,0x4C  // DPLL
0x98,0xF9,0x64  // KSV
0x98,0xFA,0x6C  // EDID
0x98,0xFB,0x68  // HDMI
0x98,0xFD,0x44  // CP

0x98,0x00,0x13
0x98,0x01,0x06
0x98,0x02,0xF2
0x98,0x03,0x40
0x98,0x04,0xaa
0x98,0x05,0x20
0x98,0x06,0xa6
0x98,0x0B,0x44
0x98,0x0c,0x42
0x98,0x14,0x3f
0x98,0x15,0x80
0x98,0x19,0x83
0x98,0x33,0x40

0x44,0xBA,0x01   // Set HDMI FreeRun
0x64,0x40,0x81   // Disable HDCP 1.1 features
0x68,0x9B,0x03   // ADI recommended setting

0x68,0xC2,0x01   // ADI recommended setting
0x68,0xC3,0x01   // ADI recommended setting

0x68,0x8D,0x04   // LFG
0x68,0x8E,0x1E   // HFG
0x68,0x1A,0x8A   // unmute audio
0x68,0x57,0xDA   // ADI recommended setting
0x68,0x58,0x01   // ADI recommended setting
0x68,0x75,0x10   // DDC drive strength

 

HDMI input cable is DVI-D Single to HDMI. So, input signal is RGB888.

But, FMC-HDMI output RGB data is different from input data.

for example, if RGB input data is lower then 0x1E1E1E(RGB 24bit), output RGB data is 0x000000

and if input data is 0x1F1F1F then FMC-HDMI output is 0x010101.

likewise,

unser 0x1E = 0x00
0x1F = 0x01
0x20 = 0x02
0x21 = 0x04
0x22 = 0x05
0x23 = 0x07
0x24 = 0x08
0x25 = 0x09
0x26 = 0x0B

and so on.........

 

I want to fix it. Plz help me.

Thenk you.

Hi @sangjin97,

Here is a forum thread that deals with the FMC-HDMI that suggests to look at the errata in the reference manual here. This refers to a Zedboard project done in vivado 2016.4 that should be a good reference for you here. 

cheers,

Jon

Hi jpeyron~!

thank you for your advice.

I have some questions.

1.What is on-board FMC EEPROM. FMC-HDMI board has no EEPROM. I checked FMC-HDMI schematic.

2. Errata describes that "Impact:minor". But my FMC-HDMI output RGB data is very strange.

1. It does have an eeprom see the ref manual https://reference.digilentinc.com/fmc_hdmi/refmanual

2. I recommend you to take a look at this thread https://ez.analog.com/thread/89940

Hi guys,

I attached a link to a tutorial where chip ADV7611 is configured and used. I use Xilinx zc702 board and FMC-HDMI Diligent,

in the tutorial I explain how to make a motion estimation application.
