Configuration 7i92 and 7i77 - get error

Not unless the config line disabled the DPLL

I changed stepgen to encoder:
and graphical interface starts.

But I get another error:
I use Intel J1900 fanless PC.

In BIOS I previously disablem all parameters that could make delay and also made isolcpu=2,3 that gives me very good latency (10k to 15k).

Do you have all power management turned off? (no C states > C1)
idle=poll in the kernel command line helps also (set with grub)

What are you ping times to the 7I92?

I will look for ping today I think, also I will add to ethernet interface settings
"hardware−irq−coalesce−rx−usecs 0" as in the hm2_eth manual
Now I read this manual for some additional help.
Also ethernet cable is very short, less than half of meter. And it also shielded to the ground. Phisicaly, ground is neutraled.

Power management, it disabled complitly in BIOS. I had very big latency delays when I bought this PC, more then 300k. After disabpling a lot of parameters in BIOS I got 30k. And after setting isolcpu=2,3, I got 15k and less.

PCW, I didn't understood, what does it mean "idle=poll", where to set it?

Also, how to disable IPV6, if I have it?

Idle=poll goes before or after the isolcpu in grub.

I've check ping to mesa board and I got

rtt min/avg/max/mdev = 0.187/0.287/1.354/0.129 ms

In hal I increased watchdog time to 1300 000 (I thing I don't make here any mistake in zeros).
And it seems, everithing work fine.

Now I start to run servos and I wonder, I've connected them to ENA pins of mesa 7i77 board (it's near analog output). What HAL pin controls this pin? Where it's written in my hal address of this pin?
