0v511 Webcam Error

  • I use an ov511 chip webcam on a embeded system. when i type " cat /dev/video0" I got the error message:
    /cygdrive/d/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/usb/media/ov511.c: init isoc: usb_submit_urb(0) ret -28
    cat: video0: No space left on device
        and my file-system is read-only file-system.Could anyone give me some advice?

    • That message just means that the driver
      returned "-ENOSPC" error code.
      You should go to look in the driver source
      where such an error message is used.

      And btw, this forum is not about Ov511
      webcams... you might get better answer
