imx8qm-mek MINISASTOCSI(mipi ov5640) camera doesn't work

[yibhan]

Hi guy,

I have searched NXP community, but I could find some of information on my issue,

As i mention on the subject, i have a problem to run MINISASTOCSI(mipi-ov5640) in imx8qm-mek.

To run mipi-ov5640, in uboot, I set up "setenv fdt_file fsl-imx8qm-mek-ov5640.dtb

below is error some of dmesg:

ov5640_mipi_v3 9-003c: 9-003c supplay DOVDD not found, using dummy regulator

ov5640_mipi_v3 9-003c: 9-003c suplpay DVDD not found, using dummy regulator

ov5640_mipi_v3 9-003c: 9-003c supplay AVDD not found, using dummy regulator

ov5640_mipi_v3 9-003c: Read reg error: reg=300a

It seems to be more setting up for running MINISASTOCSI, but i have no idea.

Could you tell me clues or link to refer?

I have one more question, there is no ov5640_mipi_v3 c file in git source. where can i find it?

I have tested ov5640 on imx8qm successfully with 5.4.24 demo images, I used "imx8qm-mek-ov5640.dtb", when the board boot up, try to use the command like:

gst-launch-1.0 v4l2src ! video/x-raw,width=640,height=480 ! waylandsink

I checked the log file, I don't have ov5640_mipi_v3, and for source code, only have ov5640_mipi_v2

I have connected MINISASTOCSI  to MIPI CSI0 or CSI1.

I connected J10 port, how about using the commad:

gst-launch-1.0 v4l2src ! video/x-raw,width=640,height=480 ! waylandsink??

Hi guys,

I have checked camera capture in 4.14.98-2.0.0

and gstreamer command is below: 

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480 ! waylandsink

I unplugged SAS cable and plug in and remove tape on camera lens, and then retried.

Thank you for your comment about gstreamer cmds.
