Hi Dan
All clocks have been checked on a scope and are running at expected frequencies.
My HPS clock is 100MHz, and the two clocks I have tested as a PTP reference runs at 100MHz (first test) and 20MHz (second test).
When I run: V J

Hi Vidar,
As a quick test can you output the clock you are using to a pin and verify its frequency on a scope?

Hi
I changed to use netdev_info (instead of netdev_dbg) logging in stmmac_main.c and then I get: V J

Hi Alex
In /var/log/boot there are no PTP debug messages.
Looking into stmmac_main.c, these PTP messages are printed from function stmmac_init_ptp using "netdev_dbg". I am not sure if these debug prints are enabled on my system?
I... V J

Vidar,
If you look through your boot log do you see either of the following debug printouts? Alexander Block
