Hi,
I'm wrestlign with BBBMini cape + kernel 4.19.
with the default dtb, the PRU is not loaded and I cannot use/start
ardupiliot with that.
After several tries and research, I found - at least I think, I had to add
this lines to the dts(am335x-boneblack-bbbmini.dts)
&pruss {
pinctrl-names = "default";
pinctrl-0 = <&pru_pins>;
status = "okay";
};
&pruss_soc_bus {
status = "okay";
pruss: pruss@4a300000 {
status = "okay";
};
};
After that, I compiled and I can have the pruss loading at boot and I
almost could run ardupilot.
By default, the ardupilot look to /dev/spidev1.0, /dev/spidev2.0 and
/dev/spidev2.1
with this change I made to enable pru, the spi are been loaded with names:
/dev/spidev0.0, /dev/spidev1.0 and /dev/spidev1.1.
What I need to change to enable the SPI dev names to the previous ?
I'm using the dtb's source from the RCNelson dtb-rebuilder project(I clone
the repo and work on that).
Thanks
