[edit] PandaBoard ES Revision History:


The PandaBoard ES provides a 5-bit board revision that may be read by Software to determine what board is being used. These board ID bits are provided by GPIO_2(BOARD_ID4), GPIO_3(BOARD_ID3), GPIO_171 (BOARD_ID2), GPIO_48 (BOARD_ID1), and GPIO_182 (BOARD_ID0).

Board_ID4 Board_ID3 Board_ID2 Board_ID1 Board_ID0 Board Type Definition
0 0 0 1 1 750-2170-002 (4460 ES1.1)-Production Board with Elpida 8Gb memory/PandaBoard ES Rev. B1
0 0 0 1 1 750-2170-002 (4460 ES1.1)-Production Board with Micron 8Gb memory/PandaBoard ES Rev. B2
0 0 1 1 1 750-2170-002 (4460 ES1.1)-Production Board with Elpida 2x4Gb memory/PandaBoard ES Rev. B3

[edit] Rev EBx

PandaBoard ES early adopter versions. On the back of the Board you will find "PandaBoard Rev EBx"

[edit] Rev B1

PandaBoard ES first production version with Elpida memory. On the back of the board you will find the following label "B1"

[edit] Rev B2

PandaBoard ES first production version with Micron memory. On the back of the board you will find the following label "B2"

[edit] PandaBoard Revision History:

PandaBoard Revision ID:
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).

Note: GPIO2 & GPIO3 (used in PandaBoard ES) are unused on a PandaBoard and if read will return back "1"

Note: Thanks to Marcin Juszkiewicz and Mans Rullgard you can use the below steps to identify the OMAP4430 silicon revision on your board. devmem2 can be downloaded from -- Board Bringup Utilities and can installed on any distro of your choice. For more information read Section 1.5 of the TRM.

devmem2 0x4A002204 OMAP4430 ES2.0 - 0x1B85202F OMAP4430 ES2.1 - 0x3B95C02F


[edit] Rev EA1

PandaBoards that will be used for the "early adopter" program will be Rev EA1:

Model #: PandaBoard Rev EA1 (This label will be printed on the back of the board)

[edit] Rev EA2

PandaBoards that will be distributed internally and to a few early adopters without the LSR connectivity module populated will be Rev EA2:

Model #: PandaBoard Rev EA2 (This label will be printed on the back of the board)

[edit] Rev EA3

PandaBoards that will be distributed internally and to a few early adopters with the LSR connectivity module populated will be Rev EA3:

Model #: PandaBoard Rev EA3 (This label will be printed on the back of the board)

[edit] Rev A1

Production versions of PandaBoards will contain the below model number:

Model #: PandaBoard Rev A1 (This label will be printed on the back of the board)

Rev A1 is the same as EA1 except it has:


OMAP4430 ES2.1 silicon


Changes to overvoltage protection circuitry which include:
* Lowered input voltage trip threshold (increased R164)
* Changed pull-up voltage on FET T1 gate(s) (adjusted values of R167/R168)
* Changed enable of U15 to be GPIO controlled (GPIO_1)
* Changed pull-up voltage to U17 ON/OFF pin (decreased R154)
* Changed resistor values & capacitor installation on U15/U17 to adjust switch timing
* Adjusted LED current limiting resistor value slightly (R165) go to higher rated part


Change VDDA_DSI1 and VDDA_DSI2 connections (from ground to VDD_VCXIO) In association, added decoupling cap at C217 near these balls
Change VDDA_CSI22 connection (from ground to VDD_VCXIO)
Moved User LED power from DC_5V to VBAT and adjusted current limiting resistors accordingly

[edit] Rev A2

Production versions of PandaBoards will contain the below model number:

Model #: PandaBoard Rev A2 (This label will be printed on the back of the board)

Rev A2 is the same as A1 except it has:
the new LSR TiWi-R2 connectivity module populated (Rev A1 of PandaBoard contained the LSR TiWi-R1 module and the footprint of the module has changed in TiWi-R2 to improve manufacturability. See the footprint migration document for more details.)

[edit] Rev A3

Latest production versions of PandaBoards will contain the below model number:

Model #: PandaBoard Rev A3 (This label will be printed on the back of the board)

Rev A3 is the same as A2 except it has:


OMAP4430 ES2.2 silicon

[edit] Rev A4

Latest production versions of PandaBoards will contain the below model number:

Model #: PandaBoard Rev A4 (This label will be printed on the back of the board)

Rev A4 is the same as A3 except it has:


OMAP4430 ES2.3 silicon

[edit] Rev A5 (Latest)

Latest production versions of PandaBoards will contain the below model number:

Model #: PandaBoard Rev A5 (This label will be printed on the back of the board)

Rev A5 is the same as A4 except it has:


Micron 8Gb lpDDR2 memory
