CCS/EK-TM4C1294XL: 1588 PTP Master directly over Ethernet

Nagesh Naik

Part Number: EK-TM4C1294XL

Tool/software: Code Composer Studio

Hi,

I want to implement 1588 PTP on this board (EK-TM4C1294XL) where I need to configure it as a master. Can I do this without the use of UDP and TCP/IP stack? How can I send the PTP packets from this board directly over Ethernet physical layer? The "ptpd-1.1.0" stack in the path TivaWare_C_Series/third_party makes use of UDP and TCP/IP. Please help me how to make use of this stack to send the PTP packets directly over Ethernet physical layer.

Thank You.

Hello Nagesh,

Please see this post from a community member describing 1588 PTP implementation: e2e.ti.com/.../2698100

Hi Ralph,

According to that post, implementation is done using UDP and TCP/IP. I want to know whether 1588 PTP can be implemented on this board without the use of UDP and TCP/IP. If yes, how can I make use of ptpd library given in the path TivaWare_C_Series/third_party/ptpd-1.1.0

Thank You.

Hello Nagesh,

From what I have read on other E2E threads, it has not been attempted to do it without UDP, but the standard doesn't require it from what I read so it may be possible without UDP. It doesn't seem TCP/IP is required.

That is the best answer I can offer as we don't have enough background to definitively say since 1588 PTP is not an application we are supporting from an apps standpoint.

Hi Ralph,

I want to send some PTP messages from this board to my PC and observe the frames in Wireshark. Can you suggest me how to do that using the ptpd library. Do I need to integrate the TCP/IP stack there. Please help.

Thank You.

Hi,
You have a duplicated post that I answered. I think we can close this thread and communicate using the other one.
