PandaBoard S/W Interface
This chapter provides details of interest regarding the SW interface of the PandaBoard implementation.
3.1
Readable Board Revision
The Panda Board provides a three-bit board revision that may be read by Software to determine what
board is being used. These board ID bits are provided by GPIO_171 (BOARD_ID2), GPIO_101
(BOARD_ID1), and GPIO_182 (BOARD_ID0). Values are as shown in Table 18 below.

Table 18: Board ID Read Values
PandaBoards that will be used for the early adopter program will have the following model number:
Model #: PandaBoard Rev EA1
Production versions of PandaBoards will contain the below model number:
Model #: PandaBoard Rev A1
Model #s are printed on a label on the back of the board.

PandaBoard Pin Multiplexing
3.2.1
Panda Base Platform Pin Multiplexing
See Table 19 for a listing of the OMAP pin multiplexing required for the OMAP4430 processor on the
PandaBoard. This table only includes the GPIOs that are connected and required for operation of the as-
shipped configuration of the PandaBoard. Unused pins are not included here as well as any GPIOs that
go to the onboard connectors. GPIOs that are connected to the Camera Expansion connector at J17 are
listed in Table 20 on page 57, while the signals connected to the Generic Expansion connectors at J3 and
J6 may be found in Table 21 on page 58.
