TDA2P-ACD: Does TI SDK support AVB protocols?

Part Number: TDA2P-ACD

Hi:

I'm a software engineer in Valeo. We are considering transmitting video streams through ethernet. I'm investigating AVB protocols, and want to know if TI SDK support the protocols.

The AVB protocols are:

1. Precise synchronization - IEEE 802.1AS: "Timing and Synchronization for Time-Sensitive Applications in Bridged Local Area Networks. "a.k.a Precision Time Protocol (PTP).

2. IEEE 1722: "Layer 2 Transport Protocol for Time-Sensitive Streams"

3. IEEE 1733: Extends RTCP for RTP Streaming over AVB-supported Networks

4. IEEE 802.1Qav: "Virtual Bridged Local Area Networks: Forwarding and Queuing for Time-Sensitive Streams"

I have downloaded the latest SDK, that is PROCESSOR_SDK_VISION_03_08_00_00.  There is an directory called "avbtp_0_10_00_00" in path "PROCESSOR_SDK_VISION_03_08_00_00\ti_components\networking\". I have read the document in it.

Now I know the SDK supports IEEE 1722, but not sure if the SDK supports others. Does any body know this?

Thank you!

    Hi,

    AVB stack has to come from customer or third parties. TI SDK doesn't offer AVB stack. What you found in SDK is for demo purpose only. It doesn't support the standard AVB protocol.

    If you are looking for AVB stack, our third party, Excelforce, can offer this on TDA2x device.

    Regards,

    Thank Stanley. I read VisionSDK_UserGuide_TDA2xx.pdf, and found paragragh "3.2 AVB Protocol Stack Support in VSDK" gives the answer to my question. 

    We'll consider Excelforce as a provider.

    Thank you.
