[Xenomai] Installing Xenomai 2.6.2.1 on kernel 3.10.53

[Xenomai] Installing Xenomai 2.6.2.1 on kernel 3.10.53

[Wolfgang Netbal]

Dear All,

I have a ipipe patched Kernel 3.10.53 that runs normally with Xenomai 
2.6.4 on an ARM imx6.
Now I have to patch Xenomai 2.6.2.1 into this Kernel ipipe combination 
for testing purpose.
When I run
# ./scripts/prepare-kernel.sh 
--linux=~/kernelDev/ipipe-3.10.53_clean/ipipe --arch=arm --default
  everything works fine, but when I start compilation with
# make LOADADDR=0x10008000 LOCALVERSION= uImage
I get the following error

If I fix this I get another error and so on and so forth.

Is it possible to run Xenomai 2.6.2.1 with Kernel 3.10.53 and ipipe ?

If yes can you please tell me where I choose the wrong way.

Kind regards

No. The most recent kernel this release can run on is 3.5.7.

If you want to use this combo, you need to fix up your Xenomai 2.6.2.1
tree. This said, I really don't understand why you insist on sticking
with outdated Xenomai release (2013?), given the sheer number of bugs
fixed since then in later releases.

I can understand the requirement for limiting the amount of new code
introduced in production systems up to some point, but releases in the
2.6.x series are about fixing bugs, not adding new features. This is why
we maintain ABI compatibility there.
