    The GUI app requires lot of memory and it is not possible to run the app with 256M Linux configuration.It requires 2G total memory

    Hi,

    The NVR GUI app can be run on a 1GB DDR board with 256MB Linux although with lesser number of Channels.

    We have not tried this yet, but we could try this out and let you know how many channels can be created with 1GB DDR configured board.

    From the A8 application perspective, you may have to reduce the number of channels and modify the GUI according to it. There are #defines like MAX_DVR_CHANNELS, MAX_CH(currently 9) which you need to change to reduce the number of channels for this configuration.

    I believe M3 memory map should not require nay modifications. But this needs to be tested to confirm this. If required, we may have to increase the memory of FRAME BUFFER(SR2) and BITS STREAM BUFFER(SR1) regions. As we are not using TILER memory in NVR GUI application, TILER memory need not be allocated and can be freed up to get extra space for SR1 and SR2 regions.

    Note: We are yet to try this combinations out. So there may be additional modifications that may be required if the need arises.

    Regards,

    Arun
