i.MX6 SoloX: Reading and piloting the PTP Hardware Clock (PHC)

[xav]

Hi,

I'm in the planning stage of my project, and it seems the i.MX6 SoloX would fit the bill perfectly.

But I would need two things:

- being able to retrieve the clock signal from the PHC on INET1

- (optionally) being able to pilot the the PHC on INET2 from an external clock

From the datasheet 1588_EVENT1OUT and friends seem to do what I want, but I couldn't find some documentation on how to use them, and a google search didn't show anything else than that datasheet. Could somebody helpfully point me at the relevant doc ?

Thanks,

     Xav

Hi Xavier

one can look at sect.24.6.10 IEEE 1588 functions

i.MX6SX Reference Manual (rev.0  2/2015)

http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6SXRM.pdf

and attached Linux Manual Chapter 46 ENET IEEE-1588 Driver.

software example in imx-test-3.14.28-1.0.0 .. /misc/doc/FSL-UT-IEEE1588-001.txt :
