SPI0.write crashes Beagleblone

[jonturner53]

Running the following code causes the BeagleBone to crash when it gets
to the SPI0.write() call. To recover, I have to reset the board.
Am I doing something wrong here?

I am new to both the BeagleBone and PyBBIO, so I may be making a newbie error.
However, I have run a few tests involving the GPIOs and they all seem to work ok.
The blinking led example works fine, so I think the installation is ok.
I currently have no circuits connected to the board, so the tests using the GPIOs
are just wiggling pins (I have checked a few using a multi-meter, make sure they're
responding).
