You don't need sudo for Ethernet card access, what you do need is the latest
mesaflash (using sudo may just give the broken mesaflash version rights to corrupt memory it doesn't own)

I think this needs to be built from source _AND_ don't build master...
Checkout 3.3 before building, master does not have the 7I96 support

Does that need fixing?

I dont know whats involved to get the latest mesaflash 3.3 changes merged into mesaflash master. Whether there even needs to be a development version of something so basic is also an open question

I have two mesaflashes now, one from the repositories and one I build from the source at github.

The repo one:
ton@LinuxCNC-MESA:~$ mesaflash 

Mesaflash version 3.3.0~pre (built on Jun 28 2017 04:15:24 with libpci 3.1.9)
Configuration and diagnostic tool for Mesa Electronics PCI(E)/ETH/EPP/USB boards
(C) 2013-2015 Michael Geszkiewicz (contact: micges@wp.pl)
(C) Mesa Electronics
Try 'mesaflash --help' for more information

The one I build from github.com/micges/mesaflash
ton@LinuxCNC-MESA:~$ mesaflash/mesaflash 

Mesaflash version 3.3.0~pre (built on Aug  1 2018 19:07:16 with libpci 3.1.9)
Configuration and diagnostic tool for Mesa Electronics PCI(E)/ETH/EPP/USB boards
(C) 2013-2015 Michael Geszkiewicz (contact: micges@wp.pl)
(C) Mesa Electronics
Try 'mesaflash --help' for more information

Both mesaflash bins give me the segmentation fault.

I can not find the version you keep referring to. Where is this magical mesaflash hidden?
Btw: I am using the master-rt repo as I want 2.8 pre.

btw2: When I check the repositories there is just one mesaflash:
This change is not coming from a source that supports changelogs.

github.com/micges/mesaflash

As I mentioned, you must checkout 3.3 _not_ mesaflash master
This has nothing to do with the LinuxCNC version
You can select the branch with a button on the left side of the file listing on
GitHub

3.3 has Latest commit 5dc2dd1 on Jun 9

(that was not really clear to me. I read it to say that the latest version was available through the repos)

Ok, it works now. Good to see that the transformers are really ssr's.

How are you managing your endstops? I modified a 7i76 wizard file for my machine but my endstops aren't showing that they're tripping.

7I96 inputs 0..11 map directly to GPIO hal pins 000..011

Have you tried using halshow to check the inputs and verify that your home and or limit switches work as expected?

I would always do this before proceeding

My switches are normally closed w/ 24v going to the input on the TB3 header.

I have my HAL file, I'm just not sure if this is the proper way to write that the pins are NC for this board, as using other examples has proved fruitless.
