FPS problem with FMC-MULTI-CAM4

Question

Hello,

I'm using FMC-MULTI-CAM4 for camera input,

but it scores only 25.5 frames per second

in max9286_serdes.h, PCLK per frame setted to 88MHz for 30fps and could go up to 99MHz

if I set the PCLK per frame to 99MHz, the camera input could achieve 30fps?

regards, hanseung.

joe dude,

Very good question.

The driver is provided as a kernel patch.

You will find it in this location in the petalinux project:

{petalinux bsp}/project-spec/meta-user/recipes-kernel/linux/linux-xlnx/0031-add-avt-multi-sensor-fmc-driver-2018.3.patch
