Expansion Connectors
The expansion interface on the board is comprised of two 46 pin
connectors, the P8 and P9 Headers. All signals on the expansion headers
are 3.3V unless otherwise indicated.
Note
Do not connect 5V logic level signals to these pins or the board will be damaged.
Note
DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD.
IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.
Figure ? shows the location of the expansion connectors.
The location and spacing of the expansion headers are the same as on
BeagleBone Black.
Connector P8
The following tables show the pinout of the P8 expansion header. The
SW is responsible for setting the default function of each pin. Refer to
the processor documentation for more information on these pins and
detailed descriptions of all of the pins listed. In some cases there may
not be enough signals to complete a group of signals that may be
required to implement a total interface.
The column heading is the pin number on the expansion header.
The GPIO row is the expected gpio identifier number in the Linux
kernel.
The BALL row is the pin number on the processor.
The REG row is the offset of the control register for the processor
pin.
The MODE # rows are the mode setting for each pin. Setting each mode
to align with the mode column will give that function on that pin.
If included, the 2nd BALL row is the pin number on the processor for
a second processor pin connected to the same pin on the expansion
header. Similarly, all row headings starting with 2nd refer to data
for this second processor pin.
Note
DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE
BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.

Notes regarding the resistors on muxed pins.
Connector P9
The following tables show the pinout of the P9 expansion header. The
SW is responsible for setting the default function of each pin. Refer to
the processor documentation for more information on these pins and
detailed descriptions of all of the pins listed. In some cases there may
not be enough signals to complete a group of signals that may be
required to implement a total interface.
The column heading is the pin number on the expansion header.
The GPIO row is the expected gpio identifier number in the Linux
kernel.
The BALL row is the pin number on the processor.
The REG row is the offset of the control register for the processor
pin.
The MODE # rows are the mode setting for each pin. Setting each mode
to align with the mode column will give that function on that pin.
If included, the 2nd BALL row is the pin number on the processor for
a second processor pin connected to the same pin on the expansion
header. Similarly, all row headings starting with 2nd refer to data
for this second processor pin.
NOTES:
DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE
BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.
In the table are the following notations:
PWR_BUT is a 5V level as pulled up internally by the TPS6590379. It
is activated by pulling the signal to GND.
Todo
(Actually, on BeagleBone AI, I believe PWR_BUT is pulled to 3.3V,
but activation is still done by pulling the signal to GND. Also, a quick
grounding of PWR_BUT will trigger a system event where shutdown can
occur, but there is no hardware power-off function like on BeagleBone
Black via this signal. It does, however, act as a hardware power-on.)
Todo
(On BeagleBone Black, SYS_RESET was a bi-directional signal, but
it is only an output from BeagleBone AI to capes on BeagleBone AI.)
