[etherlab-users] Kernel question

[Kaashoek, I. (Irene)]

Hi,

Erwin, thanks again for the files and your quick response. I have never used the xenomai kernel, I will take a look at it. I am still a bit confused by all the different versions and names that exist in the "ethercat world", I think I have to read a bit on the different rt kernels that exist.

The problems with the generic driver are solved. By changing the RTAI stack size in Simulink model > Configuration Parameters > Real-Time Workshop > Etherlab C code generation options to 3000 instead of the default 2000, my (very simple) Simulink model worked (allthough the total pc crashes when you want to do something else while running the model at 1kHz, while I had that only at 20kHz with the native driver on another pc).

Cheers,
Irene

Hi,

* Wed, May 11, 2011 - 08:48:33 +0000, Kaashoek I. Irene - irene.kaashoek at tno.nl:

> My suggestion to solve the problems would be to compile another preempt kernel, kernel 2.6.29  and then use the master and driver files from Erwin Burgstaller. Then I would perhaps need to find a slightly older version of etherlab so that it is compatible with the master.

As I'm currently very busy otherwise and I have no intentions to move to another kernel version, the only thing I can do at the moment, is provide you the matching xenomai-kernel and xenomai itself too:

http://dl.dropbox.com/u/26324125/linux-2.6.29.5-xenomai-2.4.9.tar.bz2
http://dl.dropbox.com/u/26324125/xenomai-2.4.9.tar.bz2

We're not using etherlab, so I can not provide anything for that.

Best thing would be of course, if someone will patch the latest kernels native e1000e driver, but it's very different from the previous one, so one will have to start from scratch. :-(

The NIC we're using is 'Intel Corporation 82573L'. So I'm sure it's working for this one and I don't know if it will with 82574L or 82567LM

Cheers,
 Erwin
