In embedded systems, the UIO device may not have been created in /dev due to missing udev rules.

Introduction In the world of high-performance networking, real-time systems, and embedded Linux drivers, cryptic error messages can bring development to a screeching halt. One such error— "job aborted failure in uio create address from ip address link" —is particularly frustrating because it straddles three complex domains: UIO (Userspace I/O) , network stack addressing , and job scheduling systems . One such error— "job aborted failure in uio
