It provides advanced options for the MM2S path.
•Fsync Options
This option is used to set various frame synchronization modes of AXI VDMA.
•None
Selecting this option enables AXI VDMA in free run mode. In free run mode, video data are transferred as quickly as possible without waiting for any external trigger.
Note: The channel provides a start-of-frame pulse on m_axis_mm2s_tuser(0) and can be used by downstream cores.
•mm2s fsync
When selected the AXI VDMA starts processing each frame on the falling edge of the mm2s_fsync input.
