Hi Folks,
I am using VDMA for read and write to DDR3.
I am sending the image data from image sensor 4 frames per second, in this case how to handle the data in VDMA.
I need known how to configure the VDMA for frame rate.
Please suggest me regarding this.
Thanks and Best Regards

The VDMA doesn't need to know anything about framerate. Framerate is set by the camera; most cameras just output data at whatever speed they want to with no back-pressure (ie the VDMA block has no way to adjust the speed of the camera).

Hi @u4223374,
Thank you for your replay.
Okay.
But I have doubts.
->If, I write the data into DDR3 through VDMA only one time means how many time VDMA reads the data from DDR3?.
-> It is possible to make DDR3 read operation event base through VDMA?, means If only one time write data to DDR3 through VDMA than only one time i have to read.(1 write means 1 read).
please suggest me regards these doubts please do needful.
Thanks and Best Regards
