AM625: CSI camera interface with Adv7282m, Video pipe broken

A Karthik
Prodigy 20 points
Part Number: AM625

Tool/software:

Trying to bring up Adv7282M with am625 processor using mipi interface

Configured the dtb and i2c is detected

Used adv7180.c module to build the .ko

media-ctl -p

Issue:
When trying to play media (e.g., using GStreamer or a V4L2 capture app), the pipeline fails.

Does the format conversion happen automatically between the source and sink pads  of entity 13, entity 7  ?

    Hi,

    No. You'll need to configure the format. Please refer to this FAQ: What are the common reasons V4L2 based applications fail to capture images from a probed CSI sensor?

    As provided all the format are set to " fmt:UYVY8_1X16/720x480 field:none colorspace:smpte170m"  still same error

    The "media-ctl -p" output looks correct. Not sure what could still cause the problem.

    I noticed that the sensor had "UYVY8_2X8/720x240" in the log of your first post. Please make sure the sensor is actually sending UYVY8_1X16/720x480.

    Can you try including the image format in your capture command? For example,

    v4l2-ctl --device /dev/video0 --stream-mmap --set-fmt-video=width=720,height=480,pixelformat="UYVY" --stream-mmap

    Sensor data (8-bit YCrCb 4:2:2):  MEDIA_BUS_FMT_UYVY8_2X8 (Field:none) single data lane to  

    CSI Interface: MEDIA_BUS_FMT_UYVY8_1X16  (Field:none)

    Does the conversion happens automatically?

    No, UYVY8_2X8 is not supported. Please check this E2E thread for a workaround: e2e.ti.com/.../
