    Hi,

    VPDMA specifications are under NDA. Its a quite complex IP and can only be used for HDVPSS engine. All the drivers for HDVPSS are provided as a part RDK/EZSDK stack. I think you dont need to know about VPDMA specs under normal conditions. Are you targeting any specific usecase for which drivers are not there and you want to develop drivers or something like that. Can you please let us know exact reasons for getting VPDMA specs.

    Regards,

    Hi,

    Now I need the vpdma specifications too. We just want to display the logo in uboot without the shown time limit.

    As I know, in uboot a vpdma firmware is loaded and then the logo is shown by vpdma. I think if we want to show the logo without time limit, we may be change some vpdma registers. However, we don't have the vpdma specifications, could you please share some info to me or tell me how to achieve it? Thank you very much!

    Looking forward to your reply!

    Hello,

    As Hardik said VPDMA specifications are under NDA if you are using EZSDK.

    Please contact your local FAE.

    Best Regards,

    Then has it be bound by the NDA by using the DVR_RDK?

    Thanks
