Yes, I tried to download it here.
It only gave me a blank page, I tried several times all day.
In the evening, I left the blank page open and after 10 minutes, I refreshed the blank page and the download started.
I'll try with Xilinix.
Thank you very much for everyone's help.

That's very strange as the link should not open a webpage at all since it's a direct file download link.

I managed to install Xilinix.
It's not yet clear how it will generate the bin file.
It's not even clear where to insert the finished xx.bin file so that Mesa CT can see it, I can't see the directory structure.
Pncconf only throws up a couple of configs?
Where to insert it in Pncconf so that it can see the configuration pins.
This Linux is very different. :)

Xilinx based cards use .bit files, not bin files.

When you build a 7i92 configuration (using the seveni92,xise project file),
the tools will built a bitfile named TopEtherneHostmot2.bit.
Normally you would rename this to YourNewName.bit

I recently installed linuxCnc on a RPI5 and experienced a number of connecting issues with 7i92, I want to share.
First step the ethernet connection to 10.10.10.10, fixed by setting the RPI5 address to 10.10.10.21 (ipconfig), this enabled me to ping the board.
Secondly and more time consuming was getting the first steppen motor (X-axis) to rotate.
Here mesaflash was the most important tool:
run: mesaflash --device 7I92 --addr 10.10.10.10 --readhmid

this reports the pin layout and for me it reported all pins mapped to None!

After this it became easy finding a .bit file flashed that to the board,
and now the pncconfig application for the X-axis got my steppen motor running.

I know this is only step one but now I can start tuning to the exact settings.

Your virus checker can block the download!
