[Xenomai] Xenomai-3.0.1 with raspberry pi

[Xenomai] Xenomai-3.0.1 with raspberry pi

[mosta]

Hallo everyone,

I try to compile the current stable release of xenomai for the raspberry
pi2. I found a linuxcnc installation guide for xenomai 2.6.1
(http://wiki.linuxcnc.org/cgi-bin/wiki.pl?RaspbianXenomaiBuild) and I
compiled on image with it, so I use it as a template to compile
xenomai-3.0.1 and the problem I found is that there are pre- and post
patches for the raspberry pi and I can't find any for xenomai-3.0.1 are
they not needed or do I have to create them myself?

tips and hints for moving forward are welcome.

greetings mosta

Hi Mosta,

I have written a quick guide to get Xenomai 3.0 on the Raspberry Pi 2
working at https://www.raspberrypi.org/forums/viewtopic.php?p=926466#p926466
.

It relies on a post patch written by a member of the mailing list a few
month ago.

I however find the system to be very unstable so I would love to hear some
feedback from you, especially if your system freezes or not.

Hope this helps.

Regards,

Nicolas

Thanks Nicolas for taking the time to write the guide.
I have not looked at the problem but there is port to the 4.1 kernel
from Philippe Gerum here:
http://git.xenomai.org/ipipe.git/log/?h=vendors/raspberry/ipipe-4.1
It is likely more up to date than mine.

Thanks Mathieu for the reminder. I had bookmarked Philippe's new year
message introducing the specific vendor branch, but in the interval I
somehow forgot it existed.

I was able to produce a working Xenomai 3.0 image for the Raspberry Pi 1
using the bcmrpi_defconfig as a base. It seems stable so far.

However, when using bcm2709_defconfig, the generated kernel won't boot on a
Raspberry Pi 2, leaving me with the initial rainbow screen.

Philippe, have you had any feedback from people testing on the Raspberry Pi
2 yet ?

Regards,

Nicolas

Sorry, this message was buried in a bottomless log. I received no
feedback regarding this specific target. The original work was aimed at
porting to the RPI Zero, which is the only target I have tested so far.
Other changes are untested by-products of that work, which should be
considered as a template for porting to other RPI SBCs based on the
bcm270x families.
