Pandaboard ES S/W Interface
This chapter provides details of interest regarding the SW interface of the Pandaboard ES
implementation.
3.1
Readable Board Revision
The OMAP4460 Panda Board provides a readable PCB revision that may be read by Software to
determine what board is being used. These board ID bits are shown below for the OMAP4460 and
OMAP4430 Pandaboard ESs. BOARD_ID2 and BOARD_ID0 stayed on the same GPIOs (GPIO_171
and GPIO_182, respectively), but BOARD_ID1 changed from GPIO_101 on the 4430 Pandaboard ES to
GPIO_48 on the OMAP4460 Pandaboard ES. This was necessary because GPIO_101 was utilized as the
tearing effect signal to the new DSI Display Expansion connector at J7. Values are as shown in Table 19
below.

– GPIO_2 and GPIO_3 are unused on the OMAP4430 Pandaboard ES, and if read, will both be read
back as ‘1’

Pandaboard ES Pin Multiplexing
3.2.1
Panda Base Platform Pin Multiplexing
See Table 20 for a listing of the OMAP pin multiplexing required for the OMAP4460 processor on the
Pandaboard ES. This table only includes the GPIOs that are connected and required for operation of the
as-shipped configuration of the Pandaboard ES. 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 21 on page 54, while the signals connected to the Generic Expansion connectors at J3
and J6 may be found in Table 22 on page 55.
