System Reference Manual DOC-21054 1 Introduction This document is the System Reference Manual for the Pandaboard ES, a low cost OMAP4460 based board supported through http://Pandaboard.org. This includes system setup and debugging. This document provides detailed information on the overall design and usage of the Pandaboard ES from the System perspective.
DOC-21054 OMAP4460 Pandaboard ES Overview Pandaboard ES is an OMAP4460 platform designed to provide access to as many of the powerful features of the OMAP4460 Multimedia Processor as possible, while maintaining a low cost. This will allow the user to develop software to utilize the features of the powerful OMAP4460 processor. In addition, by providing expandability via onboard connectors, the Pandaboard ES supports development of additional capabilities/functionality.
1 Pandaboard ES Board packing material 1 Shipping Box The following items can be used with the Pandaboard ES, but are NOT included in the kit. USB Cable (mini-AB to Type A) HDMI Cable (Type A) ...
See Figure 2 on page 16 for a top side view of the Panda Platform. The core components of the Pandaboard ES will be discussed in this section of the document. This would include the OMAP4460 Processor and its POP LPDDR2 memory, the input clock circuitry, the TWL6030 Power Companion IC, and the TWL6040 Audio Companion IC.
FREF_SLICER_IN input (ball AG8) of the OMAP4460 processor and the MCLK input to the TWL6040 Audio Companion IC. This clock is used as an input to the PLLs within the OMAP4460 processor so that it can generate all the internal clock frequencies required for system operation.
System and connecting peripherals TPS62361 External Power Supply (VDD_MPU) The VDD_MPU balls on the OMAP4460 processor that power the ARM cores are supplied by an external switch mode supply at U25. This device is a Texas Instruments TPS62361 switch mode supply that is controllable via the smart reflex I2C interface of the OMAP4460 processor.
The TWL6030 V1V8 SMPS provides the I/O voltage for the Pandaboard ES (net name VIO_1v8). This is a 1200mA SMPS that provides a 1.8V output that is used to power many balls on the OMAP4460 processor that set the I/O voltage for the device. It also sources onboard peripherals that require an operating voltage referenced to processor I/Os.
1.8V. The VUSB LDO is a fixed 3.3V, 35mA LDO that provides voltage to the OMAP4460 that it uses for its internal USB transceiver. The only ball powered by this LDO is the VDDA_USBA0OTG_3P3V ball (ball A5).
SYSBOOT[5] determines whether memory or peripheral booting is preferred. The SYSBOOT definitions may be found in the OMAP4460 TRM, but are included here for convenience. See Table 2 on page 24 for the SYSBOOT definitions for peripheral preferred booting, and Table 3 on page 25 for memory preferred booting SYSBOOT definitions.

DOC-21054 or lower value resistor will result in the line being sampled as a ‘1’ at reset. See Figure 3 on page 23 for the location of the resistors on SYSBOOT[5:0]. These resistors are connected to OMAP4460 as follows: ...
The input power circuitry may be found on sheet 2 of the board schematic. A block diagram of this circuitry is shown in Figure 4 below. The Pandaboard ES may be run either with or without a DC wall supply plugged into the input power jack at P3.
Texas Instruments TPS73633DBVR device which can provide up to 400mA of output current. This device may be controlled via S/W by writing OMAP4460 GPIO_1. Writing this GPIO high will enable this LDO, while writing it low will disable it (see Table 10 on page 41). This device is shown on sheet 11 of the schematic.
Debug UART Interface A single RS-232 port is provided on the Pandaboard ES via 9-pin D-sub female connector at location P4. It provides access to the UART3 interface of the OMAP4460. See Figure 5 for the implementation of the RS232 port.
Type A connector at location P2. The interface is provided using the internal HDMI module provided by the OMAP4460. See Figure 7 for a block diagram of the Pandaboard ES HDMI circuitry. This interface includes a Texas Instruments TPD12S015A HDMI Port Protection/Interface device.
HDMI interface (SCL, SDA, CEC, and HPD) from the 1.8V levels of the OMAP4460 to the 5V levels required by a TV set. It also implements a DC/DC boost converter that operates from the “battery” voltage, VBAT, and outputs a 5Vdc output that is capable of sourcing up to 55mA of current.
2.13 Display Interface The Pandaboard ES provides two possible options for the usage of the OMAP4460 parallel display signals. The first option is to use the onboard TFP410 DVI transmitter, whose output feeds an onboard DVI-D connector. The second option is to use a Display Board plugged into a pair of 20-pin LCD expansion connectors (J1 and J4).
DOC-21054 2.13.1 Parallel Display Interface See Figure 9 for a detailed block diagram of the OMAP4460 Pandaboard ES parallel display interface. (NOTE: J1/J4 are pin-compatible with the OMAP3530 BeagleBoard, so display boards designed for it may be used with the OMAP4460 Pandaboard ES).
Revision 0.1 OMAP4460 Pandaboard ES September 29, 2011 System Reference Manual DOC-21054 See Table 5 for the GPIOs used on the Parallel display interface and a description of their function. This table does not include the 28 parallel display signals (DATA[23:0], PCLK, VSYNC, HSYNC, and DE).
Table 7: LCD Expansion Connector “B” Pin Definitions (J4) 2.13.2 DSI Display Expansion Connector Interface A third display option for the Pandaboard ES is to plug an external display module into the DSI display expansion connector J7. This connector is a 40-pin, 0.8mm pitch connector (Hirose P/N FX6A-40P-0.8SV91), and is mounted on the back side of the Pandaboard ES PCB.
Revision 0.1 OMAP4460 Pandaboard ES September 29, 2011 System Reference Manual DOC-21054 Figure 10 – Panda DSI Display Connector Orientation for the pinout of J7 and a description of the signals on the connector. Any pin not Table 8 shown in is not connected.
See Figure 12 for a diagram of the Pandaboard ES connectivity to this module. See Table 9 on page 38 for a description of the GPIOs used to interface to the module and their function.
Revision 0.1 OMAP4460 Pandaboard ES September 29, 2011 System Reference Manual DOC-21054 The OMAP4460 interfaces are connected to the LS Research WiLink module as follows: SDMMC5: WLAN SDIO interface UART2: Bluetooth Host Control Interface McBSP1: Audio Digital PCM Path...
2.15 Audio Interfaces See Figure 13 for a block diagram of the audio connectivity on the OMAP4460 Pandaboard ES. In this block diagram, the signals with a red background in the box specifying their direction are analog I/Os while all others are 1.8V digital I/Os.
TWL6030 companion Power IC, which can provide up to 100mA in host mode (i.e. when a client device is connected). The Pandaboard ES may only be used in host mode if a +5Vdc power supply is installed in power jack P3.
Host USB ports, and an Ethernet interface. Two of the USB Host Ports are available via the combo connector J9, while the other two ports are available via Expansion Connector J6. The Ethernet interface is available via a tab-up RJ-45 connector at J9. See Figure 15 for a block diagram of the Pandaboard ES USBB1 interface connectivity.
1 and odd numbered pins are on the top row of the connector, and even numbered pins are on the bottom row. See Figure 16 for the placement and orientation of these two connectors on the Pandaboard ES. The distance between pin 1 of the two connectors is 300 mils or 7.62mm. Note that since these are through-hole connectors, boards can be designed to plug into the Pandaboard ES from either top or bottom, depending on user preference.

2.18 Camera Expansion Connector (J17) The Pandaboard ES does not provide an onboard camera sensor, but does provision for a 30-pin camera connector. This camera connector receives the five CSI-2 lanes of the OMAP4460 CSI21 camera interface as well as GPIOs for use on a plug-in camera module.
JTAG Connector (J8) The Pandaboard ES provides a 14-pin 0.1” (2.54mm) pitch through-hole connector at J8 as shown in Figure 17 below. In the figure below, pin 1 is the lower left pin and pin 2 is directly above it. Odd number pins are on the bottom side of the connector, and even numbered pins are along the top.

DC input jack (through a voltage divider to set the appropriate threshold). If a DC supply of more than 5V is plugged into the Pandaboard ES, the U19 output reset will be negated, which will turn on the red LED at D3 and disable load switch U16 on sheet 2 of the schematic, which will remove 5V power to the remainder of the Pandaboard ES circuitry.
NOT a pull-down. 2.21.3 SW1 – Dip/Slide Switch SW1 is slide switch that is used to provide the Pandaboard ES user with the desired value on the SYSBOOT3 input into the OMAP4460. Having this switch in the open position will cause SYSBOOT3 to be sampled as a logic ‘1’...
