Replied by Accipiter on topic MESA card (LAN) failing to connect.
I then went to /etc/hosts and changed the local host to 10.10.10.100/24 which it accepted, then went to ping 10.10.10.10 and got the so far standard response 5 packets transmitted, 0 received

I went to the network manager and tried to input 10.10.10.100/24 and it wouldn't accept the input??  Is there another way to set the host address?

No, it's not set in the IP address range of the FPGA card

I would set the host address to 10.10.10.100/24

Firmware for a 7I76EU with a 7I85 on P2 and 2 PWMgens on P3

Note that since P3 pins are unbuffered/unprotected it's best to add
a say 100 to 220 Ohm series resistor to pins connected to the rest of the system
(or use a cheap parallel port breakout card)

I am back at my problem and the same issue keeps arising.  I went through the Mesa ethernet setup tutorial, went to ping my card and nothing.  The response: 5 packets transmitted.  0 received. 100% packet loss.   I thought maybe my ethernet card was not compatible with Linux, so I tried on a second linux machine, same thing.  When I am looking at my 7i92 card with the ethernet port on the left side, I am interpreting up as away from me and down as towards me when it is lying flat on a surface.  According to my interpretation from the manual, the w5 jumper is down or towards me, and the W6 jumper is up or away from me this should give me the mesa's address as 10.10.10.10 .  I am convinced it is something basic that I am missing.  One more thing:  in the terminal I typed:  mesaflash --addr 10.10.10.10 --device=ETHER --readhmid and the response: No ETHER board found.

I can now call macros with external buttons, but unlike the buttons created and displayed on the main screen, which automatically switch QTDRAGON to MDI when clicked, with external buttons you have to manually switch to MDI for them to run. Another problem I'm having is that it can't execute macros defined as `O <XXXXXXXXX> call`. The status screen always shows "File not open," and the terminal debugs this error:

[QTvcp.QTVCP.WIDGETS.ACTION_BUTTON][DEBUG] INI MDI COMMAND #: 7 (action_button.py:717)
[QTvcp.QTVCP.QT_ACTION][DEBUG] COMMAND= O <touch_plate_z> call (qt_action.py:234)
[QTvcp.QTVCP.QT_ACTION][DEBUG] CALL_INI_MDI command:O <touch_plate_z> call (qt_action.py:249)
emc/task/emctask.cc 70: interp_error: File not open
File not open
The path where the macros are executed is defined in SUBROUTINE_PATHS= There are .ngc files to run those macros.

So 7I76EU firmware for a 7I85 on P2  and 2 PWMgens on P3 is what you want?

I got the 7I85 ;)

But I had to buy the S version... My mistake

I'll be fine if the P3 with 1 or 2 pwm and all the others P3 ports as IO if possible ?

I'm not clear on what daughter card
you have: 7I85 or 7I85S ?

I can make firmware for either.
