Camera not working

spacesaver

I followed the directions here https://www.avnet.com/wps/wcm/connect/onesite/9fe02bc9-8335-4da2-924a-1bdde941e534/RzBoard-Linux-Yocto-UserManual-v2.1.pdf?MOD=AJPERES&CACHEID=ROOTWORKSPACE.Z18_NA5A1I41L0ICD0ABNDMDDG0000-9fe02bc9-8335-4da2-924a-1bdde941e534-ogmf6kR

I'm using

Poky (Yocto Project Reference Distro) 3.1.14
Linux rzboard 5.10.83-cip1-g11a8126702 #1 SMP PREEMPT Tue Apr 5 23:00:00 UTC 2011

I also tried compiling and running app_hrnet_cam and even after some minor changes, the furthest it can get is 
VIDIOC_STREAMON, where it always fails with EPIPE. This is consistent with the yavta errors

The V4L documentation suggest EPIPE means the media-ctl commands are wrong.

Is there any other camera known to work besides ov5640? How about ov5647. I built the driver and tried it but, media-ctl won't even recognize it.

Appreciate some help.

    Hi,

    Could you try adding the following to your uEnv.txt file:

    fdt_extra_overlays=rzboard-ov5640.dtbo

    Thanks, I tried it but same exact error. This is my uEnv.txt

    fdtfile=rzboard.dtb
    enable_overlay_disp=hdmi
    enable_overlay_camera=ov5640
    fdt_extra_overlays=rzboard-ov5640.dtbo

    If there was only some way to debug what's happening in the kernel. I turned dev_debug on and it logged the ioctls, but no reason for why STREAMON failed.

    A couple things just to make sure I fully understand your setup.

    Are you using the Avnet MIPI camera? (https://www.avnet.com/shop/us/products/avnet-engineering-services/aes-acc-maax-cam1-3074457345642357172/)

    Can you verify that that rzboard-ov5640.dtbo is located under /boot/overlays?

    So you don't see anything regarding the camera when you run dmesg?

    Yes, I'm using the AVnet camera and do have the rzboard-ov5640.dtbo. I think this is proof that it loaded:

    root@rzboard:~# find /sys -name "*5640*"
    /sys/bus/i2c/drivers/ov5640
    /sys/firmware/devicetree/base/__symbols__/ov5640_vdddo_1v8
    /sys/firmware/devicetree/base/__symbols__/ov5640

    /sys/firmware/devicetree/base/__symbols__/ov5640_to_csi
    /sys/module/ov5640

    Strangely, there is nothing from dmesg by default. Here's the output after I set these to 0xff. Maybe you or someone can compare these to a working setup.

    Also, this is the firmware version I'm using that was preinstalled with the board. Maybe there's a newer prebuilt one?

    Ah, I see you're helping us through another channel. Thanks for the new kernel image. 1920x1080 works now

    Hi  

    Could you share this kernel image? 

    I also face this issue when using the camera. But the message might be different

    Here's the custom kernel I got from Evan. Thanks again Evan. He disabled the ISP on the Renesas chip. There's another ISP on the sensor itself that can downscale, but I was told it's not possible to use 640x480 because Renesas's DVP pixel clock cannot be that slow.
