Hello,

I am trying to capture hdmi 1920x1080p resolution using adv7441 chip. 

This is the code i have used for my edid.

uint8_t EDIDBuf[128]={0x00,0xff,0xff,0xff,0xff,0xff,0xff,0x00,0x4d,0x29,0x61,0x11,0x01,0x00,0x00,0x00,

                       0x08,0x14,0x01,0x03,0x80,0x33,0x1c,0x78,0x0a,0x0d,0xc9,0xa0,0x57,0x47,0x98,0x27,

                       0x12,0x48,0x4c,0x25,0x4f,0x80,0x95,0x00,0x81,0x00,0x81,0x40,0x81,0x80,0x90,0x40,

                       0xa9,0x40,0xa9,0xc0,0x81,0xc0,0xf3,0x39,0x80,0x18,0x71,0x38,0x2d,0x40,0x58,0x2c,

                       0x45,0x00,0xc4,0x8e,0x21,0x00,0x00,0x1e,0x28,0x3c,0x80,0xa0,0x70,0xb0,0x23,0x40,

                       0x30,0x20,0x36,0x00,0xc4,0x8e,0x21,0x00,0x00,0x1e,0x00,0x00,0x00,0xfc,0x00,0x43,

                       0x6f,0x67,0x4e,0x69,0x20,0x56,0x69,0x64,0x65,0x6f,0x00,0x00,0x00,0x00,0x00,0xfd,

                       0x00,0x38,0x4b,0x1e,0x53,0x11,0x00,0x0a,0x20,0x20,0x20,0x20,0x20,0x20,0x00,0x03

};

 

But i am unable to capture any resolution above 1280x720 even for vga.  Hdmi also does not sense 1980x1080p resolution. Can you please help me the needful?

Looking forward for you reply.

 

Thank You
