  • PC Camera option forces camera reboot

    Hello goprawn members,
    I am experiencing problem with using my Allwinner camera as a PC Camera. When I connect the camera to the laptop i choose the option for PC Camera. The other two options are USB Mode and Charging mode. As soon as I choose the PC Camera option a lens icon appears on the LCD screen, stays for a while and the camera reboots itself. Has anybody experienced the same and is there a fix for this? I already tried using different computers as well as different cables. The operating system is Windows 10 Pro 1909 build 18363.720.
    The info about my camera is:

    SoC:
    Allwinner V3
    Product:
    crane-sdv
    Manufacturer:
    zrj

    Please make and share your firmware backup file via cloud storage such as dropbox dot com. We can analyze the firmware and then try to find a suitable replacement firmware. Other firmware can be loaded into the camera through PhoenixSuit or a similar tool.

      The link to my firmware backup is here: https://drive.google.com/file/d/1Yod...ew?usp=sharing

      I already tried these two with no luck:The camera boots to the logo and then stops. I reverted to the original one.

        your FW info is written below. you can match at least the sensor and the LCD to other firmware.

      Thank you! I already tried several ROMs matching both LCD and the sensor. Some were successfully flashed, others not. The last time I had to recover with PhoenixCard since PhoenixSuit could not detect the camera in recovery mode. The successfully flashed ROMs did not help. The PC Camera option never works. Did Anybody find a working solution?

      You need the PhoenixCard software, which is freely available. I used version 3.1.0. You also need a backup version of the ROM as an img file as well as an SD card which normally works with the camera. When started PhoenixCard will show a graphical user interface where one can show the path to the img file using a dedicated button. Then there is a Burn button which will make the SD card bootable and the ROM will be written to it. When the SD card is prepared you need to insert it in the camera and press the power button. This will trigger flashing the ROM. In my case the LCD was powered with no indication on it. In a munite or so the LCD turned off automatically. Then I removed the card and used PhoenixCard to Format it to normal. The camera started normally and is working as usual since then. My Camera was completely irresponsive before the procedure. It did not want to turn on and the the LCD was not turning on as well when pressing the power button. It was also not able to enter Recovery mode and I was not able to use the PhoenixSuit software! Only the power light was blinking once when pressing the power button but without further progress. Using PhoenixCard I managed to recover the camera to its initial state. The procedure is like in the video shown below with the only difference that there was no progress bar when the ROM was flashed but only a white LCD, which eventually turned off when flashing was finished.

          is the above text your factory original firmware?

          if so, keep that backup. you may need it. and search for a firmware that uses the same Sensor and LCD. There are many firmware files on page 1 and on other pages throughout the thread - https://www.goprawn.com/forum/allwin...?p=130#post130

          follow this tutorial. do NOT use ADB software. start at TIME 13:50 https://youtu.be/QrTxFjIiHvc?t=830

          ---------------PORTUGUÊS---------------------

          Eu tenho a mesma câmera, NG200W. Também apresenta o mesmo problema, de reiniciar quando seleciona a opção "PC Camera".

          Algum firmware resolveu o teu problema?

          Valeu!

          --------------ENGLISH------------------

          I have the same camera, NG200W. It also has the same problem, of restarting when selecting the option "PC Camera".

          Did any firmware solve your problem?

          Thanks!
