I was able to build the third party PIXCI camlink and other 2 frame grabber and video grabber card drivers on the target using “make” command successfully now, after i reverted the realtime patch, and flashed just the primary generic version of the kernel on to target.
Now my question is how to use these built drivers on the target( .ko files which are copied on to different folder like /lib/modules/…/" etc ) on my host PC, so that each time I do flashing on to the target, I can flash these third party drivers also successfully.
