There have been a number of significant changes since the first edition
book came out.
Debian is phasing out sys-v init for systemd
UIO PRU access phased out for remoteproc by default. Refer to
http://catch22.eu/beaglebone/beaglebone-pru-uio/ for candidate instructions
on enabling UIO (though those instructions are based upon ONE Debian 8.x --
Jessie image -- Implication is that images newer than 8.6 only function
with remoteproc unless one changes the OS kernel). Similar instructions at
https://github.com/sbarral/prusst
Consider
https://www.element14.com/community/community/designcenter/single-board-computers/next-genbeaglebone/blog/2019/05/14/coding-for-the-beaglebone-pru-with-c-in-2019
which is based on Debian 9.5 -- using remoteproc, or

OTOH, it may be something as simple as needing to run using sudo (as
mentioned about halfway down http://exploringbeaglebone.com/chapter15/ [a
lot of the commentary on that page applies to first edition based upon the
date stamps -- a big jump from June 2016 to March 2019 when the 2nd edition
came out])
