Pretty much sounds correct. Did you create a file /etc/modprobe.d/pruss-blacklist.conf
and the single line in this file is: blacklist uio_pruss Can you paste in your dts file change? Here is what I have: /* pruss: pick one: */ /* * /etc/modprobe.d/pruss-blacklist.conf * * blacklist uio_pruss */ #include "am33xx-pruss-rproc.dtsi" /* * /etc/modprobe.d/pruss-blacklist.conf * * blacklist pruss * blacklist pruss_intc * blacklist pru-rproc */ /* #include "am33xx-pruss-uio.dtsi" */ The above is at this path on my board: /opt/scripts/tools/dtb-rebuilder/src/arm/am335x-bonegreen.dts So the only change is to unquote a single line in the file: #include "am33xx-pruss-rproc.dtsi" I git cloned the dtb-rebuilder into the same directory as the other utility scripts. You ran make and then make install in the dtb-rebuilder directory? I went through this process again on the latest IOT image and it worked: https://debian.beagleboard.org/images/bone-debian-8.6-iot-armhf-2016-11-06-4gb.img.xz On Thursday, November 17, 2016 at 11:56:00 PM UTC-5, Zach B wrote: > > So I finally got some time to work with the PRUs again.
