    This does not work for me.  On "make install" it results

    Any ideas?  camera defective?

          I deleted old folder and downloaded that.  Now it gets past that step but VLC shows no images.  What now?  Will send email, and post here when/if resolved..

              Yes I have made the camera work with the suggested changes.  I do not know how to get it to work with python code though, just through the terminal, but at least it proves the camera is not defective.


              Thanks

    I am having a similar problem with a new RPI 4.  All steps go through with no errors.  When I try access the camera in VLC, I Get:

    Your input can't be opened:

    VLC is unable to open the MRL 'v4l2:///dev/video0'. Check the log for details.


    OS version is:

    $ uname -a
    Linux raspberrypi 4.19.97-v7l+ #1294 SMP Thu Jan 30 13:21:14 GMT 2020 armv7l GNU/Linux


    I downloaded all files from git today.

    1. Dear ,

      Thanks for use our IMX327 RAW module.
      And really sorry about this.We did not make it clearly of quick start.

      • 1,The formate support by VLC is YUYV,Y8 or Bayer8. 
      • 2,Due to IMX327 output formate is SGRBG10P or SGRBG12P  so it is can't preview by VLC tool.
      • 3,You can use vcmipidemo tool to have a preview.


      for example:
      ./vcmipidemo -s 3000 -g 0x88 -f >/dev/null 
      it will set the exposure time to 3ms and gain value to  136 .

    Thank you for your response.


    Unfortunately, the system still does not work.  /dev/video0 simply cannot be openned.  See screenshot below.

    pi@raspberrypi:~/cam-mipi327raw/Linux_4.19.97/pi4 $ v4l2-ctl --stream-mmap --stream-count=-1 -d /dev/video0 --stream-to=/dev/null
    Cannot open device /dev/video0, exiting.

    Please let me know if you would like to see pictures of the physical configuration.


    1. Dear Customer,

        OK then. 

        The the connection is correct.

      •   Please Set up  follow Use INNO-MAKER Driver from step1 to step 4,it's really important.
      •   ”uname -a“ to see your system version, for example, if it shows Linux_4.19.75, you shoule enter "cd Linux_4.19.75/pi4"
      •   After you run "make install",  reboot the rpi, run "make setmode1"  after system reboot.
      •   Then Use “ls /dev/video0"  to see if the camera it's exist.

        If yes, "cd cam-mipi327raw/tools",    run    "./vcmipidemo -s 3000 -g 0x88 -f >/dev/null" , press enter and ctrl+alt+f1 to see  Preview

       

  7. I tried the instructions in your script several times.  Each time they do not produce /dev/video0.  See below links to the script output.

    This is a brand new Pi4 with 4GB of RAM and the latest OS.

    https://drive.google.com/file/d/1-SxR0YXmSl4R3VmGxBiPns4mjKDovrhR/view?usp=sharing 

    I am not sure what else I can do from here.  Please advise.


    1. Dear Customer,

        About cmdline.txt,it should be. "consolescma=128M",shoule be “consoles cma=128M”

    2. Also,

        Could you take a picture inside like below.

        Let me see if you received the wrong one.

         You buy it from amazon?

        Hello,

        I apologize for my english.

        I've bought last week your IMX327 camera (from Amazon).

        I've the same problem as in previous comments:

        modprobe: ERROR: could not insert 'imx327_i2c': Exec format error

        make: *** (Makefile:50: install) Error 1

        I've a PI3 B with latest firmware (Linux 4.19.118-v7+)

        Can you provide please a solution?

        Is the software open-source? Can I have the source in order to recompile for further evolution of the OS?

        Thanks in advance

        1. Dear Customer,
          Tools are open sourece.
          Could you send me information show of command "uname -a" ?

        2. We will recompile and provide drivers according to stable system release.

            Hello.

            Output of uname -a command is:

            Linux raspberrypi 4.19.118-v7+ #1311 SMP Mon Apr 27 14:21:24 BST 2020 armv7l GNU/Linux


            Ok, I think to understand that TOOLS are open source but DRIVERS isn't open. It's right?

            Best Regards

            1. please download from our github, we update drivers which support linux 4.19.118

                Hi,

                I didn't found the update drivers on your gitee nor on your github (last modification on gitee was 2 months ago).

                Maybe I used wrong links. Please, can you verify and attach the correct link where I can found the update.

                Many Thanks

                    Ok,

                    now the driver seems to be installed. I will try the camera and give you a feedback next days.

                    Regards

    Is there any way to download the driver without having to create a gitee account???

    I don't see any way to convert the video into RGB - the vcmipidemo script appears to be doing this but its source is not available.  Do you have anything that shows how to convert the SGRGB10P to RGB?  Currently thinking of returning this as it doesn't seem easy to use... MIPI327-ISP is much better.

    Hello,

    Please let me know the pixel format of images captured by using ./v4l2_capture_raw12 command.

    It seems that the device is working fine because the size of the generated files is correct and the values of the data in the file seems to be pixels of an image.

    v4l2-ctl --all shows that the pixel format is 'pRCC'. 

    Format Video Capture:
    Width/Height : 1920/1080
    Pixel Format : 'pRCC' (12-bit Bayer RGRG/GBGB Packed)

    AFAIK, 'pRCC' format is defined in the following page.

    https://www.kernel.org/doc/html/latest/userspace-api/media/v4l/pixfmt-srggb12p.html

    I processed the generated image according to the information in the page above but the processed image does not look right.

    I'd appreciate for any advice and information.

    Best Regards,

    Yoichi

        Does this mean that RG ad GB are alternatively placed in a line?

        1. Anonymous

          R-G-R-G-R-G........

          G-B-G-B-G-B........

          That's to say RG and GB in different line.
