i’ll take a look at it as soon as I get some free time ; I have a working,
GPS master clock.

Hi James,
Yes, Espressif is doing a good work adding support to it.
I hope in the future others silicon vendors start to contribute as
well (hello ST, Microchip, Renesas, ...)
Very nice James, I think PTP will be very useful.
Please let me know if you want some help with tests, etc.
BR,
Alan
wow, it is really well supported!
OK I will start looking at a PTP server implementation and work on client later…

Yes, it is supported: serial and network (ethernet and WiFi).

Outstanding!
Serial and Network…
Thank you

Hi James,
ESP32 is supported, which features do you need?

I haven’t looked at it yet, but I am working on ESP32; is WROOM supported
in master or just the S3/C3?

That is probably the most important step right now. Hardware support
can be added as needed.
The TM4C129 Tiva-C ARM platform has hardware support for P
Hi all,
What's the current status of this? I'm also interested in adding PTP
support to NuttX, especially on ESP32 if that's possible - I haven't done
any research yet regarding the hardware capabilities of ESP32 in this
matter.
As a first step I was thinking of adding support for the PTP daemon,
Thanks Arie,
Yes, very true, it depends on your application!
My statement about what makes a good clock is very subjective. This
all depends on your application, your measurement and of course your jitter.
- For Wireless AV, a 10ms gps clock is fine.
- For Wireless Earbuds, a 10us clock is requi
Beware of that 1PPS signal. A few years ago I bought several GPS modules and
compared the signals. Some differ by exactly 100ns (within 2ns, the accuracy of
my scope) from others, and that is not the width of the pulse, that is much
wider, I compared only the edge that are comes close to the ot
Related to this, I have a GPS receiver generating PPS interrupts on SAME70.
It would be a perfect GMC - Atomic clock sync!
I will look at this when I get a chance. I have a lot of upstream
contributions from HW platforms I have done
over the last 5 years or so with myself and others ... I need some
Yes, it’s good stuff. I will look at it next year.

Great project! I've done a few commercial implementation of PHY
timestamping protocols - IEEE1588 for Ethernet 802.3
and the WLAN version (802.11v2012) for 802.11n. Products with that
technology are still shipping today (but that was 10 years
ago now). Both are key foundations and building blocks f
Hi Markus,
I don't know if there is someone already using PTP with NuttX
(probably since NuttX is used by many industrial automation
companies).
I think the first step should be add a PTP daemon for NuttX.
The ptpd could be a good candidate: https://github.com/ptpd/ptpd

Dear all,
I'm just investigating NuttX a bit as there is definitely more and more
momentum coming about it.
I was just wondering if PTP (IEEE1588) is supported or if this is planned
for the future? Currently, it doesn't look like this, however some Eth-MAC
drivers have at least some register-defin
