Re: [Xenomai] RE : RE : RE : RE : No boot kernel with xenomai on i.MX6Q Sabrelite

[Roberto Bielli <roberto.bielli@axelsw.it>]

Hi,

i'm try to do the same things (porting xenomai 2.6.2.1 on imx6q sabresd 
kernel ) and i have the same error ('Switching to clocksource ipipe_tsc' 
on boot the kernel).
The steps was these:
1. patch the kernel with the prepare-kernel.sh with the correct CFLAGS 
and LDFLAGS (adeos-ipipe-3.0.36-arm-1.18-11.patch)
2. apply the post patch (adeos-ipipe-3.0.36-arm-1.18-11-post.patch)
3. boot the new kernel
4. show the error 'Switching to clocksource ipipe_tsc'

i have some simple question.
1. There is a solution actually for this (are there some kernel 
particular options to enable/disable)?

thanks for all.
