HI @shengdishd ,

An interrupt should be generated by the VCU at the end of each frame :

I guess  you need to use this interupt for your locking.

In the zcu106 board, video frames decoded by VCU are stored in memory, and then the Video Frame Buffer Read/Write v2.1
IP core reads out video frames from memory and outputs them to SDI interface. The Video Frame Buffer Read/Write v2.1
IP Core can operate Genlock Synchronization in Software in the yellow. How does this genlock external synchronization work?

Hi @shengdishd ,

From the highlighted text, it clearly mentions that the genlock synchronization needs to be done in SW... I believe using the interrupts is the correct way to go.

The genlock synchronization needs to be done in SW. Do you have any examples design for reference? Or documentation of related operation instructions.

Hi @shengdishd ,

I am not sure if there are examples. Did you try to check the VCU TRD?

VCU.pngHow the related application program in Application(user) calls the related library files in the red line in SDK software?

Hi @shengdishd ,

We do not have any baremetal driver for the VCU (if this is what you mean by in SDK software). Users are expected to use linux OS on the platform.
