Other Parts Discussed in Thread: TVP5158

I use dm368+ tvp5158 to capture 2-CH D1 video. “DM365_5F00_DVR_5F00_DVSDK3_5F00_00.02.00.00” is ported in my board.

but stauts Register is 0x13, bit 2 is always 0, so Vertical sync is not locked .

I attached the tvp5158 reg data and schematic diagram.

please give me some advice .

I can't see anything obviously wrong.

Do all 4 status registers report the same unlock?

BR,

Steve

Don't forget there are 4 cores. You must select the desired core before reading/writing any settings.Registers FEh and FFh select the core to read/write.
