You are welcome.

You should pay attention to L2 cache: if you experience high latencies
it could be a culprit (see cache write disable handling in
arch/arm/mm/cache-l2x0.c). For everything else, I have found all things
I needed in documentation and mailing-list.

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

2017-03-20 Thread Cédric Perles 
Hi Mauro,

In fact, I was booting the wrong kernel through tftp. Using the correct one, 
I have indeed IPIPE and XENOMAI running.
Sorry for bothering you and thx for your time.

By the way, is there any classical traps to know concerning Xeno 3.0.3 on 
iMX6 ?

Regards

Cédric

I use ipipe-core-4.1.18-arm-9 from git.xenomai.org without problem.
Configuration comes from Yocto's meta-freescale layer defconfig.

AFAIK no, you don't need anything from rootfs to enable i-pipe in kernel.


So running from console

dmesg | grep -i -e pipe -e xenomai

doesn't show nothing?

AFAIK no, you don't need anything from rootfs to enable i-pipe in
kernel.

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

2017-03-20 Thread Cédric Perles 
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 ?

Cédric

Hi Cédric,

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