Please help me !!!
I am designing a custom board with DM8168 vs decoder TVP7002.
I can control TVP7002 throught I2c
But TVP7002 can not detect video modes when query_dv_preset, No SOGOUT.
I am using ezsdk ezsdk_dm816x-evm_5_05_02_00
This my Schematics with tvp7002
This is my all values of Register TVP7002. I am using for video mode 720p 3 wire
