error finishing read and joint following error.

Its clear that the IRQ pinning did not work so can
you try running this script and re-trying LinuxCNC?

(look at it first, never run a script especially one you must run as root
without a careful examination)

 

chmod +x pinirq.txt
then
sudo ./pinirq.txt enp5s0
linuxcnc


 

sorry i missed this but ip a reports;

Did you try the pinirq script?

Note: it will only pin the IRQ temporarily unless you disable irqbalance
 

yes i did. i am unable to ping the board and i have a watchdog bite error. i also ran checkmask again and the IRQ changed from 30 to 29

i don't understand why i can't connect to the 7i96s now. when i run mesaflash --addr 10.10.10.10 --device=ETHER --readhmid it tells me there is no board found. and pncconf can't find the board either. or even mesaflash --device 7i96s --addr 10.10.10.10 --readhmid , no 7i96s found.

What does "ip a" report now?
 

it reports the same as before. i don't know what the deal with that computer is. linuxcnc runs flawlessly on the duo-core laptop and i think thats what i am gong to use for now. i have been messing with this computer for a month at least trying to get linuxcnc working on it and it just doesn't want to work. for whatever reason. i gonna just use the laptop and that will be its only job, running linuxcnc, which it does very well. i just want to start using my machine, and the longer i mess with that desktop, its time i am not milling. i appreciate all your help. ill put it on the back burner for now and maybe i will visit it again in the futrure. thank you very much for you knowledge and patients. i WILL need your expertise again.

Note that this overlaps your other address:

Allowing a normal internet packet to get routed out of the real time interface
Not sure that would cause your issues but you might try setting enp5s0's netmask
to /24 (so 10.10.10.255) rather than /8 (10.255.255.255)
 

how would i do that exactly? through edit connections? the same way i created the connection?

sorry, i understand after looking at it for a few minutes. i will give it try. thank you.
