Sounds good. Let's hope it keeps that way.
I ran the RPi4 for some time and it was ok, so the Rpi5 should be ok too?
Latency isn't so much of an issue now with the "-" sign.
That "should" keep it on track (sync).
You can check if it isn't doing so great with the value of the pin lcec.0.pll-reset-count
If that is way above 1 there may be a problem.
First thing to do then is to increase lcec.0.pll-step to 10000 which is max, or something in between say 5000,
setp lcec.0.pll-step 10000
If pll-reset-count then keeps increasing you need to work on the latency.
The main reason I switched to Intel-based is that the gui became more and more
sophisticated and needed more and more processing power to function smoothly.
I am hesitant to recommend a setup, there are many that works fine.
For ethercat I would definitely look for an Intel network adapter,
the rest is more form factor, power draw, cpu performance.
I have had good luck with the N100/N150 mini pcs. Intel network adapter though.
