YES, that is the rub! Robert's description of what to do had to be stared at a bit, but actually it is very easy and it worked first time.
I've got a BB Green, so I will re-iterate the particular steps required for Remoteproc: 1. Clone Robert's github repository: git clone https://github.com/RobertCNelson/dtb-rebuilder 2. cd dtb-rebuilder/ cd src/arm 3. Now you will need to find and edit the top of the device tree dts file. For BBG, this is: am335x-bonegreen.dts The only thing you have to do is to uncomment: /* #include "am33xx-pruss-rproc.dtsi" */ unquote the line: #include "am33xx-pruss-rproc.dtsi" Save and exit. 4. cd /etc/modprobe.d Create a new file named: pruss-blacklist.conf Add this single line to the file: blacklist uio_pruss Save and exit. 5. cd back to dtb-rebuilder make sudo make install sudo reboot After the above process, PRUs entries appear in /sys/bus/platform/devices, and the RPMsg example with character device in /dev is working! I will add the above process steps to the chapter on PRU compiler set-up in my Remoteproc ADC github project. Thanks!
