7i80 and 7i77

What OS version and distribution are you running?

You will need to setup grub to boot the preemt-rt kernel

Holding the shift key when booting will invoke the grub boot menu (not sure if this is universal)

The uspace version of linuxcnc that hm2_eth uses requires a Preemt-RT kernel

Now I have installed the 5th different Ubuntu version. In each case I can't install the RT Preempt. I fear, I use a board that I can't use with this. Today I will try an old s775 Board that I have sent to retirement. I hope I can install the supplement on this board. If yes, I will try to run it on the newer board, that is (I hope) a good part faster.

here I think are easiest steps to run 7i80:

1. Install debian www.linuxcnc.org/binary.hybrid.iso
2. install packages 3. Install linuxcnc sources from git: linuxcnc.org/docs/2.5/html/code/Contribu...nc_official_git_repo
4. build it and run it using my instructions few messages ago.

Also if you use the latest LinuxCNC ISO (Debian Wheezy)

www.linuxcnc.org/index.php/english/download

There's a pre-built Debian Preemt-RT kernel package available:

sudo apt-get install linux-image-3.2.0-4-rt-amd64

You still need to install/run linuxcnc master (2.7)

If you use Wheezy, there's a pre-built linuxcnc master (2.7) binary for Preemt-RT here:

buildbot.linuxcnc.org/

(master-rtpreempt)

I have now found, that its important, that the RT Version have the same number (except the last Servicerelease Nr) like the Kernel Nr.
I can now install, the 3.10.4 but obviously I need a later version than the 2.6.32 to upgrade, because the RT version don't started correctly. Its a difficult thing, if you never have anything to do with linux, to find informations for this operating system.
Some pages are made for people, who have things like this sucked with Mothermilk, but I understand nothing
Download the program, install it and it runs (more or less) correctly, that is ok with a rar in Windows, but unfortunately linux want it completly different.

Just verified that the latest LinuxCNC Wheezy ISO works fine with the 7I80
after building master and installing the standard preemt-rt kernel as mentioned above
