Hi.
Does FreeRTOS supports gptp protocol
If you are referring to Precision Time Protocol (IEEE-1588), FreeRTOS currently doesn’t support it.
You can take a look at these older threads for more discussions related to this topic:
There is also required hardware support for gPTP (ie PHYs that can identify PTP frames and time stamp them.
Also, support for that kind of protocol is hardly ever included in the OS but a network layer (you are more likely to find it in FreeRTOS+TCP).
Hello tony,
Thanks for the reply , yes I was mentioning about IEEE 802.1AS which is a part of IEEE-1588
ok RAc. my intention is to have a system , in which there should be one time master and many slaves. The time master provides the time to its slave and the whole system has a common time
I know, that is what (g)PTP is all about. Does not change anything about what I wrote earlier. The time stamp support is required for all gPTP devices, ie ordinary clocks (master only and slave only), pure relay instances, and relay instances that also contain ordinary clocks.
