STM32H7 PTP NETXDUO

[FB__1]

Hello,

I would like to know if this PTP client example from Netxduo can be used on an STM32H723 MCU: 

https://github.com/eclipse-threadx/rtos-docs/blob/main/rtos-docs/netx-duo/netx-duo-ptp-client/chapter1.md

Another MCU, the STM32N6 has this implementation here: https://github.com/STMicroelectronics/STM32CubeN6/tree/main/Projects/NUCLEO-N657X0-Q/Applications/NetXDuo/Nx_PTP_Client

I wanted to confirm if the STM32H723 does support that example because i am looking at https://github.com/STMicroelectronics/x-cube-azrtos-h7/tree/main/Projects and I cannot find any ...

Thank you.

Yes, some time ago.

But since my own experiments with PTP offload (sync quality decreasing with ethernet traffic, compared to stable PTPd) I skipped it.

I read the code of STM32N6，netxduo ptpclient.c and found the ptp implentmation is base on software clock.

Not base on ethernet ptp registers.

I am satisfied with the NETXDUO PTP performance. I got very good precision below 1usec with the NETXDUO PTP client on the STM32N6 and ptp4l.

I used :

//PPS control register:

TRGTMODSEL[1:0] = 00b -> Interrupt-only mode

PPSEN0 = 1 to enable PPS channel 0
