I have a running system with Linux ls1021atwr 3.12.37-rt51+ls1+gf488de6 #11 SMP Thu Jun 22 17:12:20 CST 2017 armv7l GNU/Linux.
I'm using the 1.8 SDK for the LS1021A-TWR.
I wanted to apply the xenomai-kernel but I noticed that there isn't a ipipe-patch for the kernel-Version 3.12.37.
But there is a patch for 3.10 or 3.14. My question is: How can I upgrade or downgrade the kernel Version running at the ls1021A-TWR.
My first steps were to add a recipe in recipes-kernel of the meta-fsl-arm folder which fetches the 3.10 kernel-version of the freescale linux.git repository. Unfortunately I couldn't start the kernel, it hangs on "Starting Kernel". Are there any further conditions which to be set to get an older kernel working?
