On the TI branch, we don't ship a default PRU driver, it's up to you to configure it.. git clone https://github.com/RobertCNelson/dtb-rebuilder cd ./dtb-rebuilder/ You have the "black", so edit one of the following: #default: emmc + hdmi enabled: nano src/arm/am335x-boneblack.dts #: all overlays (emmc/hdmi disabled) nano src/arm/am335x-boneblack-overlay.dts #emmc enabled: hdmi disabled src/arm/am335x-boneblack-emmc-overlay.dts then look: uio_pruss (3.8.x compabitl) /* * /etc/modprobe.d/pruss-blacklist.conf * * blacklist uio_pruss */ /* #include "am33xx-pruss-rproc.dtsi" */ Or remoteproc: /* * /etc/modprobe.d/pruss-blacklist.conf * * blacklist pruss * blacklist pruss_intc * blacklist pru-rproc */ /* #include "am33xx-pruss-uio.dtsi" */ So "pick on" copy the "blacklist.conf" settings and un-comment out the "#include".. Then just: make sudo make install sudo reboot Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
