MESA 7I92 programming was created by TJ
Hello.
I need help.
I have never dealt with Linux or Linux CNC before.
All other Winxx CNC programs I use are Mach3-UCCNC-MASSO.
I bought a MESA 7I92 card.
I installed the latest Linux CNC.
I installed MESA CT.
I downloaded all the xx.bin files for 7I92.
There is nothing that suits me.
I have custom expansion cards that I would like to adjust to their pinout.
I would like to edit them according to my individual needs.
I installed EFINITY so that I could edit an existing one to my needs, but I only found the xx.bin file.
I can't find (freeby.mesanet.com/7i92step.zip) is it gone or I don't know.
According to the descriptions, it has a 7I92xx.vhd extension that I could edit with EFINITY.
Please help me where I can get xx.vhd files.
Thanks in advance.

I assume you have a 7I92T{x}, the 7I92 uses a Xilinx tool chain, not Efinix

Can you post the pinout of your expansion card?

Note that pinouts are more flexible than you may think
because of the ability to trade off GPIO with specific pin functions,
so its likely that if you expansion card has a parallel port like pinout
that an existing configuration will work.

In the source, the files that determine the configuration pinout
are all named PIN_xxxxxx.vhd. taking an existing one of these files,
copying it to new file, the editing the new file to suit is the normal
procedure to create a new configuration. In addition to creating new
pinout file, the new pinout file needs to be added to the project
and included in the top level source.

Hi I found a 7I92_7I76x1dpl.bit which would be good.According to its description, it also has 2 PWM outputs onP2 7-8 I/O.Unfortunately, the description and reality are not the same.It doesn't have a PWM output.
The card has 2 IDC 26 connectors.
1 connector standard LPT assignment 1-25. 26 pins +5V
2 connectors 1-17 pin input 18-25 GND 26 pin +5V

Where can I get the 7I92_xxx.vhd files?

First, make sure what 7i92 you have, there is 7i92/7i92M/etc, then there is 7i92T/7i92TM/etc, meaning with T and without T, they have the same functionality, but use different FPGA so flashing the wrong firmware is not good.
They always have a sticker on the back with the model written.

First, it's still not clear whether you have a 7I92 or 7I92T(x)

The support software zip file that has all the sources and project files
needed to build firmware files is downloadable from Mesa's webstore
(in the specification tab for the appropriate card)

CT identifies it as Mesa 7I92 and suggests corresponding files for upload.
I uploaded several files to it as a test. It works fine.
Test assembled on the table CNC program moves the motor + outputs and inputs work.

You would need the Xilinx tool chain (Webpack 14.7)  for a 7I92, 7I92H, 7I92M

A Mesa webáruházban, ha a támogatásra kattintok, csak egy üres ablakot hoz fel.
(www.mesanet.com/software/parallel/7i92.zip) vagy bármilyen más.
Csak a letölthető PDF.
Or is it just me that the download from the MESA site doesn't work?
Ezért kérdezem, hogy hol érhető el még a teljes kód.

It opens a blank site but should download a .zip file (or open a popup about downloading a zip file with all the source files).

This is what I get when I click on the link in your last post:
