Hi,
I am writing to request some Details about the Xenomai using for an Udoo
Neo.
In my currently Thesis I'm working for the first time with an real-time
System.
One objective therefore is to install Xenomai 3 on the Udoo Neo board
with an iMX6 multicore Processor.
For the board exist a Linux-Version on the base of the Linux kernel
3.14.56.
For this kernel Version there no i-pipe patch available. This is why I
was looking for differences in the affected Files of the kernel 3.14.44
and 3.14.56 and Change the i-pipe-patch when there are differences.
Afterwards, I was able to patch the Udoo Neo Kernel, to make the config,
the bzImage and the modules and Install it from an Computer with
Linux-OS to the SD-Card as described in the Documentation.
At that time of the Installation I kept on working with the Udoo Neo
Board. For Configuring and building the ARM libraries I use the commands
./scripts/bootstrap
sudo ../configure CFLAGS="-march=armv7-a" LDFLAGS="-march=armv7-a"
--with-core=cobalt --enable-smp
After the make install Command I wanted to test the Installation with
dmesg | grep -i xenomai
where I get the Output
[ 0.147853] [[01;31m[KXenomai[m[K] scheduling class idle
registered.
[ 0.147865] [[01;31m[KXenomai[m[K] scheduling class rt
registered.
[ 0.148004] [[01;31m[KXenomai[m[K] init failed, code -19
the full dmesg output in this time frame is
[ 0.146610] Bus freq driver module loaded
[ 0.147489] futex hash table entries: 256 (order: 2, 16384 bytes)
[ 0.147909] [Xenomai] scheduling class idle registered.
[ 0.147921] [Xenomai] scheduling class rt registered.
[ 0.148021] I-pipe: high-resolution clock not working
[ 0.148063] [Xenomai] init failed, code -19
[ 0.155688] VFS: Disk quotas dquot_6.5.2
[ 0.155999] Dquot-cache hash table entries: 1024 (order 0, 4096
bytes)
In the Archive of this mailing list I could find posts with similar
Problems, where the user have to Change the Frequency scaling in the
defconfig data.
But when I tried to disable the Frequency scaling with "make
menuconfig", the kernel of Udoo can't compile.
I hope someone will have an idea to find a solution for this Problem.
