Note that the above script for installing master and building the uspace linuxcnc variant
installs a RIP version so you need to follow the README file in linuxcnc-dev:
The Ethernet FPGA cards have built in firmware like the 5I25 so don't need or want a firmware name on the loadrt command line
something like:

Here is where hm2_eth is : (assuming the script ran properly)to run the software go back to the top level directory (linuxcnc-dev in my case), and issue:
. scripts/rip-environment

ls ~/linuxcnc-dev/src/hal/drivers/mesa-hostmot2/hm2_eth.c

something like:

Ok, It seems the Program runs now. For a short test of the 7i76E, I need the stepconf program and before I must enter the loadrt hostmot_2 and after that the loadrt hm2-eth.. Now linuxcnc and I can edit the files with either stepconf or the other for servothreads. Is it right?

Stepconf is for parallel port configuration, for Mesa cards, pncconf is used
pncconf does not support the Ethernet FPGA cards yet but you can do this:
For a 7I76e config run pncconf and select a 5i25/7i76 combination
do whatever configuration you like and when you are done edit the hal file that pncconf
creates, changing the loadrt hm2_pci line and globally replacing "5i25" with "7i76e"
You will also have to remove the loadrt probe_parport line
for a very simple 7I76E sample file you can try this freeby.mesanet.com/7i76es1.zip
This is basically the hm2-stepper demo file modified for PID feedback and a few line changed to
support Ethernet

I have now tried at least 3 days to edit a specimen file from the linuxcnc folders. If I try to search the file in PNCconf I can't see any file in the files window. If I copy and paste one of the files, they should be in the folder, I can see any file in there. But if I choose a file.ini the program found a lot of errors.
In my self made (but incorrect because I don't know what I must enter in the boxes from connector2 and 3) file, there is a additional file with the filending pncconf. How can I make such a file from the specimens.
At the moment I want only to run the 7i76E with a single Servo and a single Steppermotor, only to see if and how it runs. After that I want to connect the second board and the serial IO board because the other 2 boards have not as much connectors as I need.

as a quick start, try:
download freeby.mesanet.com/7i76es1.zip
cp 7i76es1.zip ~/linuxcnc/configs
cd ~/linuxcnc/configs
unzip 7i76es1.zip
setup RIP environment
launch linuxcnc
(it should report version 2.7 pre)
select 7i76es1
report findings
Before you start, you need a working, unused Ethernet port
and you need to at the minimum set up that port for manual config IPV4
with an appropriate IP address and netmask
(you can test if its working by pinging the 7I76E)
If you read the hm2_eth man page, it has instructions to setup linux so that
linuxcnc has exclusive access to the real time Ethernet port, but this is not needed for a quick test

Thats all to be expected if the network connection is not setup
you need to setup the Ethernet connection that connects to the 7i76E before
attempting to run linuxcnc
in other words if you cannot ping the card, you wont get any further

I have tried to disable the IPv6 Connection and add the Mac Adress to the hm2_eth. Without any success.
Pibg said Network is unreachable, but I have no problem with the Internet connection, that runs with normal speed.

Looks like you have not setup a static ip address network connection to the 7I76e
Note that for real time access, the 7I76E must be the only device on that particular network
If you are not using the 192.168.1.x IP address range you can leave the 7I76E at its default
192.168.1.121 address and setup the IPV4 settings for dedicated (to real time) Ethermet MAC
to "manual" with a 192.168.1.1 static IP address and 255.255.255.0 netmask
If you _are_ using the 192.168.1.x range for your normal Internet connection you should set the
7I76E's EEPROM IP address to something else (10.10.10.10 suggested) and setup the dedicated link
with a static IP address of 10.10.10.1 (for example)

Now I'm a little bit ahead. After half a day browsing through several Linux Sites I could make it that I have a static linux adress,
for the moment only in the terminal, but thats not so bad, because I often need an Internet connection on the new computer.
With the static adress, thats not really good.
But now Linuxnc can't find the Mac-adress of the board, or if I write the adress it don't know the parameter.
That's the result of ping
