Hi all,

 

I met some problems in using EVAL-ADV7612-7511P(only use 7511) and AVES2 .


The condition is as following:

Input data: YUV422 ITU-R BT.601Type(Y8bit, C8bit, Vsync, Hsync, Clock)--HITACHI DI-SC120R camera.
            1280(H) x 720(V), 25/P  ASP is 16:9,
            clock 30MHz, Horizontal 18.75kHz, Vertical 25Hz.

            8bit color depth, Separate Hsync, Vsync,
           
            NO Audio data. NO DE.

And the Data pin connection(see addition JPG file):

               IMG_20141013_134014.jpg
              Y[7:0]-->D_TX[35:28] of J5,

              CbCr[7:0]-->D_TX[23:16] of J5 , J6
              Clock --> VCLK_TX of J4
              Hsync, Vsync  --> HSYNC_TX, VSYNC_TX of J4
               Gnd  --> GND
               NO DE.
 
             OUTPUT TV: from 7511 HDMI to KONKA LED32E330C HDMI

 

Here are registers and value that I configured according to my conditon.

72 41 10 ; 0x41[6] = 0b0 for power-up – power-down,  0x41[4] = 0b1 Must be set to Default Value

72 98 03 ; 0x98 = 0x03       Fixed registers that must be set on power up
72 9A E0 ; 0x9A[7:5] = 0b111,Must be set to 0b1110000*
72 9C 30 ; 0x9C = 0x30
72 9D 61 ; 0x9D[1:0] = 0b01 , [7:4]Fixed,Must be set to Default Value
72 A2 A4 ; 0xA2 = 0xA4
72 A3 A4 ; 0xA3 = 0xA4
72 E0 D0 ; 0xE0[7:0] = 0xD0
72 F9 00 ; 0xF9[7:0] = 0x00,Fixed,Must be set 00

72 15 01 ; 0x15[3:0] – Video Format ID 1 = 4:2:2 (default = 4:4:4)
72 16 B9 ; 0x16[5:4] – Input Color Depth 11 = 8 bit for 4:2:2 (default = 12 bit),[7]-Output Format 1 = 4:2:2 , [3,2] Input Style 10 = style 1,[0]-Output colorspace  1 = YCbCr
72 17 03 ; 0x17[1] – Aspect ratio of input video (4x3 = 0b0, 16x9 = 0b1),[0]0b1 DE Generator Enable
72 18 00 ; 0x18[7] = 0b1 for YCbCr to RGB – CSC Enable
72 48 00 ; [5]Fixed,Must be set to Default Value 0, [4:3]Video Input Justification,00 = evenly distributed
72 AF 06 ; 0xAF[1] = 0b1 for HDMI – Manual HDMI(1) or DVI(0) mode select,[3:2]Must be set to Default Value 01 , [0]Must be set to Default Value 0
72 56 20 ; 0x56[5:4] - 01 = 4:3, 10 = 16:9
 

72 35 40 ; Register Settings for DE Generation ,1280(H) x 720(V) 720P-25fps Mode1
72 36 D9 ; 0x40 and 0xD9 of Register 0x35 and 0x36 for 720P-25fps, Is it right??? If NO,please tell me the corrected value.
72 37 0A ;
72 38 00 ;
72 39 2D ;
72 3A 00 ;
72 FB 04 ; Hsync Delay MSB ,Vsync Delay MSB(DE Generation),Width MSB,Height MSB,[2:1] = 0b10,Vsync 25Hz,Low Refresh Rate (VIC Detection)


Now, when powering up the chip, the HPD state(0x42[6]=1) is HIGH.  0x42[5]=1,0x9E[4]=1, PLL is locked. 0x41=0x10.

But, It's no image on the TV.
I need your help.
Thank you very much.
