??? ?

Part Number: TDA4VM

Tool/software:

I want to know if SDK_8.05 supports the gPTP protocol stack? Or as I noticed in the example, only PTP protocol stack is supported.

Hi,

TI RTOS SDK has PTP stack in 8.5 SDK.

EthFw application for CPSW9G using PTP stack for Timesync with External Network.

Note:
The PTP stack in SDK 8.5 is not for production support, it is only for test purpose.

TI Latest SDK 9.2 has PTP example from PDK ENT module with Production support gPTP Stack.

Hi，

Does SDK 9.2 support GPTP protocol stack in both A72 and MCU2_0, or only in MCU2_0。

A2 uses HLOS Like Linux/QNX.

Linux & QNX has PTP support from kernel.

MCU2_0 is R5F running using RTOS application using the PTP stack from PDK.

Please refer to SDK Documentations & User Guides for more details from Software development details on ti.com

Does the PTP referred to here refer to the PTP protocol stack or the gPTP protocol stack? We may need to use the gPTP protocol stack。Does SDK 9.1 also support it? I saw in SDK 9.1 that r5f seems to have an integrated gPTP protocol stack. Does Linux need a kernel in 9.2 to support the GPTP protocol stack?
