[Xenomai-help] 2.4.6.1 blackfin patches

[Mike McTernan]

Hi,

Does anyone have a working Adeos patch for the top of the Blackfin 2008R1 non-SMP branch to get up to 2.4.6.1?  The patch supplied with Xenomai doesn't cleanly apply, and after massaging would not compile:

Adding some #include's produced yet more errors of a similar nature.

adeos-ipipe-2008R1.5-RC3-bf5xx-1.8-00 applies cleanly against the official
2008R1.5-RC3 uClinux distribution. Until recently, I was only tracking official
release milestones.

Since Adeos is now part of the official uClinux distro for the blackfin, I'm now
tracking their development head instead; you can now find
adeos-ipipe-2.6.28-blackfin.git-1.9-00 which applies to the blackfin.uclinux.org
GIT tree at git://sources.blackfin.uclinux.org/git/readonly-mirrors/linux-kernel.git

ksrc/arch/blackfin/patches/README should give you that information.

I wasn't holding out much hope for taking Adeos from one place, Blackfin
uClinux from another and Xenomai from here.  However, the patch at this
location does indeed patch and build against the Blackfin 2008R1:

http://download.gna.org/adeos/patches/v2.6/blackfin/adeos-ipipe-2008R1.5
-RC3-bf5xx-1.8-00.patch

Hooray!  And sorry for the obvious question.

Regards,

Mike

Yes, I can confirm that.  It's good for the top of the 2008R1 branch
too.

That's excellent, although all the work I do is on the 2008R1 branch of
Bfin uClinux as that's well tested and stable.
