[Xenomai] Trying to install Xenomai 3.0.3 on i.MX6 Kernel 4.1.15

Hi Mauro,

First of all, thx for your answer. Knowing that Xenomai 3.0.3 is possible on 
iMX6 kernel 4.1.15 is already a relief for me.

I compile my kernel through BuildRoot that automatically builds the .config 
file.
However, when I check into kernel menuconfig, I can see I-PIPE is selected 
(kernel Features -> -*- Interrupt pipeline) and Xenomai is selected ([*] 
Xenomai/cobalt ).
My .config file is also OK (CONFIG_IPIPE=y , CONFIG_IPIPE_CORE=y, 
CONFIG_XENOMAI=y).

==> What IPIPE patch did you use ?
==> Does IPIPE need something from RootFS ?

Regards,

Cédric

Hi Cédric,

I'm using Xenomai 3.0.3 with 4.1.15 kernel from NXP community with success.

What defconfig have you used to configure your kernel? Before build it, did 
you check with 'make menuconfig' that i-pipe was enabled?
