Thank you for the hint Intel_JEspinoza, but I have already read Sergey's post before, when searching information.
Since I have not used Yocto Project tools before, then I give a fast look to its documentation and read there are three types of kernel types in BSP descriptions: KTYPE "tiny", "standard" and "rt-preempt".
However I need to know if the Intel BSP v0.7.5.7 or v0.9.0.7 are configurable to easily switch to rt-preempt editing few lines of code or passing through big efforts and deep-knowledge of Yocto Project.
I suppose a Yocto Project expert user could answer this question in a very short time. Thanks a lot.
Regards,
Luca
Update: I tried to download a 3.12.6 kernel and patch it with its RT_PREEMPT using the BSP image-spi generated toolchain generated before. in brief: make menuconfig to set fully preemptible kernel and check high resolution timer support PATH=$PATH:[...]/sysroots/clanton/usr/bin make ARCH=x86 and CROSS-COMPILER=[...]/sysroots/clanton/usr/bin/i586-uclibc....- when the kernel "bzImage" file is produced, I substituted it on the "image-spi" micro SD, but the board freezes at boot after: #Clanton Microcode Version a0_1_00_23 [Linux-EFI, setup=0x1091, size=0x222d80] [Initrd, addr=0xd82f000, size=0x30fd89]
