If you are running 2.8 then you might be good to go, if you are running on the correct kernel.

What does uname -a say?

Hello again
I have know a CNC build, and when I put the power the 3 steper motor are lock by the power.
The Mesa 7I96 is supply
The Debian is installed with "linuxcnc-stretch-uspace-i386-r10.iso"
I have upgraded the LinuxCNC to 2.8
but when I launch the LinuxCNC he ask me to set the ini configuration file.
In the menu I select Interface/Mesa/hm2-steper
and the list propose only :
3x20-small
4i65
4i68
5i20
5i22-(big and small)
5i23
7i43-(big and small)
7i90

but no 7i96 ou even 7i76E

I have try 7i90 but I get an error....
Any idea to configure ?

PS : for information, when I try a ping on 192.168.1.121, it does not answer..

Here is an example skeleton hal/ini file for the 7I96 and LinuxCNC 2.8:

freeby.mesanet.com/7i96-2.8.zip

I would suggest reading the LinuxCNC hal documentation/tutorial to get an idea how configuration is done in LinuxCNC

linuxcnc.org/docs/

In addition, for Mesa Ethernet cards, I would read the hm2_eth driver manual page:

man hm2_eth (from a terminal window)

You should not expect to ping the 7I96 card unless your network connection is setup properly (the hm2_eth manual page outlines how to do this)

In fact I had a cable problem.
I solve it and 192.168.1.121 ping :-)
I decided to change the IP adress to 192.168.0.140 (an address on my local network..) and no error with the mesaflash command.
But now I can't ping anymore (neither on 192.168.1 nor on 192.168.0)

I will have a look on the documantation above to understand :-)

thanks

If you read the hm2_eth manual page you will see that it suggests using
10.10.10.1 for the host IP address and 10.10.10.10 for the Ethernet FPGA card
address (this is selected with a jumper on the 7I96 card)

This is because other than for basic setup, you do not want IP address range overlap with your local network connections

Yes I try this conf but I think when I have set the IP address to 192.168.0.140, I have replace the 10.10.10.10 which is store in EPROM.
Know I have a direct Ethernet cable between the debian and the Mesa card.
But what ever the jumper W5&6 are, I don't succeed to connect to the messa card.
I am know in the hm2_eth recommanded configuration.

I will have a look in mesa documantation to see if it is possible to reset the card to factory default...

If you set W5 and W6 low, (and cycle 7I96 power) the 7I96 will use
192.168.1.121

I would do that, set your host IP address to 192.168.1.10 and then reset the 7I96s EEPROM address to 10.10.10.10. Then start over with a host address of 10.10.10.1 as suggested

You don not want the 7I96 realtime connection IP address to overlap your local network address range

I recover the connection to the board with jumper down and 192.168.1.121
maybe is it beter to power the mesa after the network is well configure on the computer.

I will stay on this network. No need to go to 10.10.10.10 as I am know with a direct cable, and the 2 only device on this "LAN" are the mesa and the computer.

I am kown looking at the skeleton hal/ini.

Thanks for support :-)

If you ever have a normal network connection is should be on a separate subnet. This is not related to cabling. That is why 10.10.10.x is suggested as a default real time connection address, since it will never overlap with normal IPV4 NAT ranges

I would also suggest you use the EEPROM address of 10.10.10.10, I do this with moth my machines 1 using a 7i76e and 1 using a 7i96. Jumpers should be W5=down W6=up. I have the line at the top of my hal files:
loadrt hm2_eth board_ip="10.10.10.10"
PCW can probably confirm whether that is necessary, may just be necessary if using BootP jumper settings.

In the future you will likely want to network your machine's PC as doing configuration, sending Gcode files, and making changes to it is over remote desktop or VNC is typically much easier than sitting at the machine itself.
