unfortunately I lost the kernel sources for a specific kernel I am using (4.14.159-rt70-3.0.3+gfff496c).
Is there any possibility to get the kernel sources for this kernel in particular from your git?
I do not have any build date.
4.14.159-rt70-3.0.3+gfff496c points to the BSP built from this manifest.
We maintain the ‘standard’ kernel sources in our git and when building with the RT patch we do apply the RT patch as part of the Yocto build.
And since it is a NXP downstream based kernel we had to add some additonal patches to make the RT patch apply, build and at least run.
So you would have to checkout the particular kernel sources from our git and then apply said patch.
The git hash of your particular kernel is fff496c, the additional patches and the order in which to apply them can be found in the kernel recipe:
