TDA4VEN-Q1: Kernel crashes when capturing custom camera

Meng-Hung Chen
Prodigy 70 points
Part Number: TDA4VEN-Q1

Tool/software:

Hi TI,

        We got a custom camera (w/ built-in TI-953 Ser) from our vendor. Its parameters are Sony ISX021 sensor, 1920x1280, 30 FPS, FPD-Link III, MIPI 4 Lane YUV422 8bits. Now we want to apply it to our TDA4VEN platform. The settings before capturing the frame are:

(We detect TI960/954 Deser on the fourth I2C bus so we also update the /boot/dtb/ti/k3-j722s-evm-fpdlink-fusion.dtbo and apply it at booting)

Thus, we use v4l2-ctl -d/dev/video3 --stream-mmap --stream-to=frame-raw --stream-count=1, but the kernel crashes:

    Hi Brijesh,

            After I rebuild and install u-boot in SDK by make u-boot_install and re-run the commands above, the kernel still crashes.

    I'm not sure the change is applied correctly or not.

    (BTW, I realize I pasted the wrong message of fourth block of code. The real resolution for it should all be set at UYVY/1920x1280.)

    Sure, the attachment is the output from `dmesg`. (Note: It contains some commands to set up the deserializer, media-ctl, and v4l2-ctl.)

    Hi Chen,

    It seems camera is not getting probed, Can you check with your camera vendor for the drivers, we don't support driver for isx021.

    I noticed that a few days ago and we tried another sensor with imx390, then, the problem was solved.

    However, it keeps hanging on the line 88 (dequeuing) in the test code:
