Original question:

SK-AM62: which CSI camera we can use for AM62 SK EVM?

SK-AM62: cannot capture images at 1080P30 with camera OV5640(ALINX AN5641)

Part Number: SK-AM62
Other Parts Discussed in Thread: AM62P

Tool/software:

according to this advice,i used ALINX AN5641 on the AM62P EVM to test 1080p30 display and encoding.
I tried two ov5640.dtbo in the PROCESSOR-SDK-LINUX-AM62P(10.00.07.04),none of them worked.
  1. k3-am62x-sk-csi2-ov5640.dtbo:The frame rate is 30 frames, but the image is abnormal.
  2. k3-am62x-sk-csi2-tevi-ov5640.dtbo:The image is normal, but the frame rate is only 15 frames at all resolutions.

    Hi Linyang,

    Can you try v4l2 streaming and see if it gives you 30fps, for example:

    v4l2-ctl -d2 --set-fmt-video=width=1920,height=1080,pixelformat='YUYV'  --stream-mmap

    Thank you.
