Hi,

I working on DM8127 IPNC i try to create /dev/video* node

    Hello Raj,

    I am not familiar with IPNC.

    It seems to me  like you have an out of memory condition, or at least an out of enough contiguous memory for the  driver condition. You could try by increasing the amount of memory you give to Linux, it looks like you are running with a mem=80M kernel boot option which seems to me a bit smaller.

    Hope this help,

    Best Regards,

    Margarita

    Hi Margarita,

    Thank you for your suggestion now i set  mem=126M it creates /dev/video1 /dev/video2 /dev/video3 but video1,2,3 are the display drivers for capturing i need /dev/video0?

    i don't no how to do? kindly help us

    Thanks and Regards

    Hello Raj,

    As I said I am not familiar with IPNC.

    Are you want to use v4l2 for capture?

    I am not sure is this support in IPNC.

    I will try to evolve someone to help here.

    I would suggest you to contact your FAE for IPNC support.

    Best Regards,

    Margarita

    Hello,

    V4L2 is not suppported in IPNC RDK codebase, please refer to documetns and guide for more details on the system architecture and code details

    The video drivers like capture, encode run on M3 co-processors and not on A8

    Hi Raghu,

    I have ported opencv to the IPNCAM8127j3. I want to run the canny edge detection algorithm inside the Camera. But I don't know how to capture the input from the camera directly from the minicom terminal. Kindly help me with the procedure to capture the camera image directly using the camera driver.

    Thanks and Regards

    Hi RAJ,

     

    It looks like it could not allocate memory get_free_pages API. Typically, get_free_pages is used for allocating small amount of memory, could you check how much it is trying to allocate? If it is in terms of MB, it will not be able to allocate. You probably may require to use vram to allocate memory.

    Hi ,

    i insert the module(ti81xxfb.ko) in my DM8127 ipnc. it creates /dev/fb0. i capture image using IE and save into sdcard. my question is how to display the image(snap.jpg) on HDMI output through /dev /fb0.please help us to do this work.

    I already tried saFbDisplay.c sample application it displays RGB values on my HDMI output.
