Right. GRUB is pretty much a x86-only program. Most ARM boards use uBoot.
The Raspberry-Pi's use their own thing and are the only (?) ARM boards that
that need a FAT /boot partition.
Typing 'help' at the boot loader prompt will get you a list of commands.

I am looking into installing Xenomai with a RT kenel based on 4.4.91-ti-r133,
but the Xenomai install documentation I am finding talks about building/using
a 3.8 vintage kernel. Is this documentation valid for the 4.4.91-ti-r133

Should be fine. If it is like the BeagleBoneBlack or PocketBeagle the USB

Or you can do what Adafruit did: use it in write-only mode. Or not use the
hardware SPI at all, and just bit-bang some GPIO pins. I think the GPIO pins
can be set to a bi-directional mod
Well, /usr/include/spi/spidev.h on my Raspberry Pi actually talks about
sending 9-bit messages in its comments... So, I am *presuming* that it is

If I am applying a 5V power supply to the Vin pin (P1-1) of a Pocket Beagle
(say from an expansion board that includes a power supply), is it safe to also
plug in a [powered] micro-USB cable? That is, does the Pocket Beagle have a
power protection / isolation circuit?
