Hi, I'm not quite sure whats the problem is but if its for just enabling and running the PRU along with its I/O's i prefer to go with cape-universala.
plus I too faced a similar error while programming PRU under kernel 4.+ so later downgraded my kernel to 3.8.45 and enabled cape-universala so it worked for me. Hope this helps.
