AM3356: Not able to find the PTP demo code

Hello,

We only have PTP demo in Linux SDK: https://software-dl.ti.com/processor-sdk-linux/esd/docs/07_03_00_005/linux/Industrial_Protocols_PTP.html.

Thanks for the respond. do you have the source code for this demo? I could not find it. 

Thanks

Man Lung

Also, do you have any documentation/reference for AM3356 ? I found some online, but not sure if this is for AM3356. 

Thanks

Is Linux-based PTP demo good for you?

I think this will be a good start point if this is the only demo that you have. I will love to take a look first. Thanks

Please check this training video: https://training.ti.com/ptp-procsdk-linux-ptp-on-linux?cu=1136194. 

Please also refer to this thread for some relevant information.

Thanks for the video. where can I find the source code? Thanks

Thanks so much

HI. I looked at the code. I found out the driver code is in the kernel. Can please you share the ptp kernel with me? 

Thanks. 

Please check the release notes for kernel source code.

hi. I downloaded Kernel Version: 5.4.106.  looking for the ptp driver. However, I did not see the ptp in this version. am I missing something? sorry, I am new for linus kernel. 

Hello,

Did you take a look at the README for the linuxptp repo at https://git.ti.com/cgit/processor-sdk/linuxptp/tree/README.org ?

Regards,

Nick

Nick:

Thanks for the link. I read the the linuxptp repo. However, I already got the code from linuxptp repo. and it only said I should use linux kernel version 2.6.30 or later.

I was able to get a file call prueth.c from your website. However, I did not see the complete kernel code. 

Thanks

Nick. In addition, i could find some implementation in https://www.ti.com/tool/PROCESSOR-SDK-AM335X#downloads the am335x-evm-linux-rt-sdk-src-07.03.00.005.tar.xz . However, I am looking for the RX_SYNC_TIMESTAMP_OFFSET_P1 and RX_PDELAY_REQ_TIMESTAMP_OFFSET_P1 which is missing. and also I want to look at the PRUETH driver, PRUPTP driver and CPTS driver. Thanks

Hello Man Lung,

Apologies for the delayed response - I reassigned this thread to myself so I see your replies here as well as on your other thread. For future readers, the other thread is at https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1069028/am3356-not-able-to-find-the-kernel-code-for-the-ptp-implementation

The AM335x Linux SDK includes the Linux drivers you discussed. More details about PTP are hiding in the kernel driver documentation for CPSW > CPTS:
https://software-dl.ti.com/processor-sdk-linux/esd/docs/07_03_00_005/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/CPSW.html , search for section "Common Platform Time Sync (CPTS) module".

Regards,

Nick
