help with mesa 7i76e connection

hi everyone. just got my mesa 7i76e in the mail today.
i connected it to the 24v power supply all the light blinking.
i am using linuxcnc-stretch-uspace-amd64-r13 on a live usb just to connect to it and see if it works before i start tearing apart my machine.
i just cant connect to it.
i manually changed the ipv4 to 10.10.10.10 moved w3 jumper to the up position and when i ping 10.10.10.10 it works.
when i use the command mesaflash --device 7i76e --addr 10.10.10.10 --readhmid
i get an error no 7i76e board found.
i also spent half of my day on the search page searching for any obvious things i might have missed.

can i use live usb to even connect to it or i have to install it first?
if i can use liveusb what am i doing wrong?

thanks to anyone willing to help.

ok now i am able to get some reaction from mesaflash!!!!!!!!!!!!!
thank you!!!!
also the ethtool command isnt working "command not found"
how can this be fixed?

thanks again!!!

You need to set your host IP address to something _other_ than 10.10.10.10
If the 7I76E is set for 10.10.10.10, the host address should be something like 10.10.10.20

EDIT sorry didn't notice that you got that part solved

You should be able to install ethtool with

sudo apt-get install ethtool

thank you for the reply anyway.
i got that part sorted as well(i just thought it would come pre-installed with the ISO)
im connecting it to my vfd now.
im also dealing with some jitter errors in linuxcnc.
hopefully ill get that sorted as well today.
