Chinese Mesa 7I92 from aliexpress NEW was created by Sekai
Hi.I bought a mesa card from aliexpress to power my lathe.The board works with 10.10.10.10 it pings and output that gives me with command:sudo mesaflash --device 7i92 --addr 10.10.10.10 --readhmid
The problem is i dont know how configure linuxcnc. I have the doc from the seller uploadnow.io/f/9v0gkpb
This is my first time with mesa card.

You did not buy a Mesa card. You bought a Chinese clone hoping to save some money then expecting help.
The best thing you can do is read the Linuxcnc documentation.
But any of the quirks with the card itself you are going to have get support from the vendor.
Without knowledge of the schematics no one can say whether it will operate electrically as original Mesa 7i92.
What you have done is bought a rip-off and now expecting those that are loyal to Mesa Electronics to dig you out of hole.
And to be perfectly honest there are plenty of threads regarding configuration, plenty of resources on YouTube and plenty of advice in the docs.

The basic issue is that the current firmware is just GPIO (no Step/Dir hardware etc)
There could be a couple reasons for this:
1. The wrong firmware is installed,
2. The card had corrupted firmware so has loaded the fallback firmware (which is just GPIO)
Did the card vendor supply a firmware file?, it does not look like any standard 7I92 firmware to me
If they did supply firmware, I would try re-writing it with:
mesaflash --device 7i92 --addr 10.10.10.10 --write vendor_supplied_firmware_file_name.bit --reload

You are right.
the firmware that the seller gave me was 7i92_G540x2D_custom.bit
I did upload it but it gave an error when i started linuxcnc
I install Mesa Configuration Tools and download a firmware from there the 7i92_G540x2D without the custom part and it works.
For now i just tested the pin output
The next problem is when i start linuxcnc it gave me an error: Watchdog has bit!
from the post "Mesa 7i97 Watchdog has bit!" i did latency-histogram --nobase --sbinsize 1000 and its like this:
btw the pc is minipc Fujitsu Esprimo Q920

The watchdog error is a sign of network latency issues.
I would try:
sudo chrt 99 ping -i .001 -q-c 60000 10.10.10.10
which should run for 1 minute and then print timing statistics
to see if this is the issue.

I think the max value is to high.
Maybe the cpu needs to tweak?

Nope, the network driver needs to be changed, installing the DKMS version of the Realtek drives should fix it.
Give this a try:

With Intel, be sure to set up the coalescing settings. Type man hm2_eth and follow the instructionsI dont think i have a realtek ethernet
