Kernel Version: ubuntu-armhf 3.8.13-bone20
Overlay File: BB-BONE-PRU-00A0.dts (shown below)
Compile: sudo sh -c "dtc -@ -O dtb -o BB-BONE-PRU-00A0.dtbo
BB-BONE-PRU-00A0.dts"
worked as far as I can tell
Loading:
/lib/firmware\> echo $SLOTS
/sys/devices/bone_capemgr.9/slots
sudo sh -c "echo BB-BONE-PRU > $SLOTS"
worked as far as I can tell except when dmesg examined
