Beaglebone Blue - pru-rproc driver not loaded - yes, I've searched here.. sorry

[Michael Ball]

I've included uname, rc_test_drivers, and  /opt/scripts/tools/version.sh, and lsmod | grep pru here. 

running latest image from emmc and fully updated.  

I'm feeling like quite the noob.  I've followed a dozen different suggestions from 2017-2019... It feels as if this board has been abandoned? 

What might I be missing?   Appreciate any suggestions you may have.

You have "2" uboot_overlay_pru defines in /boot/uEnv.txt...

Disable the "AM335X-PRU-UIO-00A0.dtbo" version and reboot..

Oy...  Yes, I *just* read elsewhere that it's *either UIO *or RPROC.   Thank you.  Appreciated.
