Now P9_21 is free for the MiniDisplay to use.
NOTE
In future Bone images, all of the pins will already be allocated as part of the main device tree
using runtime pinmux helpers and configured at runtime using the config-pin utility . This
would eliminate the need for device tree overlays in most cases.
Now, configure it for the MiniDisplay and run a test:
bone# echo BB-SPIDEV0 > $SLOTS
bone# ./minidisplay-test
You then see Boris, as shown in Figure 9-4 .
