Sorry but I don't know how to find which firmware my device has.. I need to read more to find that.

Meanwhile I tried both selection available. But both didn't work..

Will check once again..

You would be best staying with LinuxCNC 2.9 as you will always get warnings
that the 7I96S is unsupported and has unknown firmware modules with LinuxCNC 2.8

A 7I96S as shipped will have 7i96s_d firmware (1 encoder)
You should be able to edit the hal file and change the number of encoders

Ok thanks PCW, I will once again try to get it working. If you have any clue on how to resolve the error that I am getting while running LinuxCNC 2.9, it would be very helpful.

I am using Raspberry Pi 4B 8GB. In one of the post I have elaborated about the error that I am receiving.

I downloaded
git clone github.com/LinuxCNC/linuxcnc.git

I believe it gives latest of 2.8 master branch

Then followed the instructions
linuxcnc.org/docs/html/code/building-linuxcnc.html

I had to download many dependency packages manually as somehow it was not being found during install. But I made sure I am installing the same version as its looking for.

I had to build with following option as it was giving some GPL related error
./configure --enable-non-distributable=yes

All test cases ran with 0 errors.

However I still see following when run dpkg-checkbuilddeps command

dpkg-checkbuilddeps: error: Unmet build dependencies: asciidoc (>= 8.5) dblatex (>= 0.2.12) docbook-xsl dvipng w3c-linkchecker xsltproc texlive-lang-french texlive-lang-german texlive-lang-polish texlive-lang-spanish asciidoc-dblatex texlive-xetex

Finally I got the LinuxCNC up and working by installing package python3-gi-cairo

This package was not installed and should be added in the package dependency list.

Glad you got it going.

The python3-gi-cairo dependency seems to be there in master branch:
github.com/LinuxCNC/linuxcnc/blob/88b54c...trol.main-pkg.in#L15

I can see it in the copy I have. I followed the steps as given in help page to build linuxCNC. But it didn't pick up as part of running dpkg-checkbuilddeps
