I get the reference design from the website—— When I read the project, I have a question. In the cf_hdmi.c, there is some code to set the VDMA 's base address.

From the picture, we can know that  the address of 3 frame buffer is the same address——VIDEO_BASEADDR. I want to use three different address to cache the video, so I can just modify the frame buffer into three different address, but I don't know whether  the project will automatically display  the video in the three frame buffers and how long the data in three frame buffers should maintain?
