Debian jessie + Mesa 7i76E was created by jtc
Hi!

My plans is to upgrade to debian jessie, and use Mesa 7i76E boards for a new machine configuration. So I make this post in advance to see if I'm making something wrong and save some time.


For what I search, on this topic: linuxcnc.org/index.php/english/forum/9-i...d-mesa-ethernet-card, mesa ethernet cards need a Preempt kernel, and linuxcnc-uspace, my question is what is the differences between linuxcnc-uspace and the "normal" LCNC?


I find this instructions, linuxcnc.org/docs/2.7/html/getting-start...th_preempt_rt_kernel, so I hope its just install like is described, but and if I want to install in a RunInPlace configuration? there is a specific branch?


Any advices will be welcome.

No, you just run configure with --with-realtime=uspace (or let it self-discover what brand of realtime system you have)

The guide covers it, but just to emphasise it.

Jessie does not have a stock rt-preempt kernel. Their kernel maintainer was supposed to be introducing one, but it has not happened yet.

I was not aware there was a backport, but that should work.

The alternative is to build your own, this thread has a link to the docs and some other info

I'm not comfortable to build a build a kernel, so looks like I will compile the RunInPlace version to use uspace.

Regarding the mesa 7i76E, I should use a straight Ethernet cable? I searched for this information but didn't find anything.

Any Ethernet cable will do (straight through or crossover)

The PHY on the 7I76E has whats called MDIX which means it figures out
if the TX/RX pairs are swapped and swaps them internally if it needs to

I have make a new debian installation on another pc . already intall the rt kernel, but when try this command:

sudo apt-key adv --keyserver hkp://keys.gnupg.net --recv-key 8f374fef


I got his message:
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.cGAkwK5HjW --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-security-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-stable.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-squeeze-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-squeeze-stable.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-wheezy-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-wheezy-stable.gpg --keyserver hkp://keys.gnupg.net --recv-key 8f374fef

Host not found... any clue how to solve it?

If you google for "keys.gnupg.net: Host not found" then a number of possibilities will be presented.
It looks like the trick is to use a different key server.

(This actually has nothing much to do with LinuxCNC)

changing the host to the ip adress solve the problem.


now, another problems...

I create a new configuration with Pncconf and configure manually the ip adress of the pc.

I can ping the board:
jtc@jtctech:~/linuxcnc/configs/mesa7i76e$ ping 192.168.1.121

I suspected that the board had the wrong firmware, but when try to verify:

last day I spend 2 our 3 hours try to find the solution but without success. the only information closer that I can find is in the this thread:
forum.linuxcnc.org/forum/27-driver-board...80-and-7i77?start=70
but nothing like this problem.

this is my network settings:
