    • WELCOME TO BEAGLE BOARD OVER VIEW
    • BEAGLE BOARD MEANS• Bring your own peripherals• Entry-level cost ($149/179)• ARM Cortex-A8 (superscalar)• Graphics and DSP accelerated• Linux and open source community• Environment for innovators
    • BEAGLE BOARD HISTORY• IT AS TWO VERSIONS 1)BEAGLE BOARD• 2)BEAGLE BOARD XM• Feb 2008: Rev A concept demonstrated at meeting with key kernel maintainers and open source developers at TIDC• Jun 2008: Rev B launched broad availability with Digit-Key• Mar 2009: First hands-on ESC BYOES training• May 2009: Rev C doubles RAM to 256MB• Jan 2010: Rev C4 bumps performance to 720MHz and resolves USB power supply stability issue• Jun 2010: xM Rev A board demonstrated at hands-on ESC BYOES training
    • BEAGLE BOARD WHY? SD USB Stereo in Stereo out Power DVI-D Note: Beagle Board can be powered from the alternate jack (as shown) or via USB
    • WHY PRODUCTION OF BEAGLE BOARDXMIN BEAGLE BOARD THERE IS NO OVER VOLTGE PROTECTION CIRCUIT.IT IS HAVING ONLY ONE USB,NO INSERTION OF MMC CARD,CAMERA HEADER,MMC3 EXPANTION,MCBSP,IT IS HAVING ONLY 256MB OF MEMORY AS COMPARE TO THE BEAGLE BOARD XM.
    • BEAGLE BOARD Peripheral I/OOMAP3530 Processor  DVI-D video out 720MHz** Cortex-A8 3.1”  SD/MMC+  NEON+VFPv3  16KB/16KB L1$  S-Video out  256KB L2$  USB 2.0 HS OTG 430MHz C64x+ DSP  I2C, I2S, SPI,  32K/32K L1$  48K L1D MMC/SD  32K L2  JTAG PowerVR SGX GPU  Stereo in/out 64K on-chip RAM  Alternate powerPOP Memory 256MB* LPDDR RAM  RS-232 serial 256MB NAND flash* Revisions before C had 128MB** Revisions before C4 were 600MHz USB Powered  2W maximum consumption  OMAP is small % of that  Many adapter options  Car, wall, battery, solar, …
    • Collaboration at BeagleBoard.orgBEAGLE BOARD REV  Live chat 24/7 via IRC  Links to project downloads 3.1”Other Features 4 LEDs Peripheral I/O  USR0  DVI-D video out  USR1  SD/MMC+  PMU_STAT  S-Video out  PWR 2 buttons  USB HS on-the-go  USER  I2C, I2S, SPI,  RESET MMC/SD 4 boot sources  JTAG  SD/MMC  Stereo in/out  NAND flash  Alternate power  USB  RS-232 serial  Serial
    • REVISION C 3.1”Peripheral I/O 256MB LPDDR RAM USB HS/host-only (up from 128MB) (in addition to existing USB HS on-the-go) LCD expansion
    • BEAGLE BOARD XM• XM • 2,000 Dhrystone MIPS performance with ARM® Cortex™-A8 • 512MB POP memory enabling – Native builds of Ubuntu and other distros – More multitasking with complex apps like Firefox or OpenOffice.org • Robust expansion with more direct connectivity without external hubs; on-board Ethernet and five USB 2.0 xM means ports Extra MHz • USB-powered board via low power $1 and processor integration Extra MB • Active and growing open source community at beagleboard.org 9
    • BEAGLE BOARD XM
    • BEAGLE BOARD FEATURESOMAP PROCESSOR 3530HS USB 2.0 OTG PortHS USB 2.0 Host PortStereo Audio Output ConnectorStereo Audio In ConnectorS-Video ConnectorDVI-D ConnectorLCD HeaderBUTTONS&INDICATORSSD/MMC 6 in 1 Connector->WiFi Cards->o Camera ->Bluetooth Cards-> GPS Modules ->SD Memory Cards ->MMC Memory Cards-> SDIO Cards->MMCMobile cards-> RS-MMC Cards-> miniSD Cards
    • RESET AND USER BUTTON• WHEN RESET BUTTON IS PRESSED• o USB• o UART• o MMC1• o NAND• WHEN USER USER BUTTON IS PRESSED• o NAND• o USB• o UART3• o MMC1
    • POWER SUPPLY 1)USB OTG SUPPLY 2)DC SUPPLY
    • POWER SUPPLY: Voltage 5.0 V Current 500mA (minimum) mAConnector 2.1mm x 5.5mm Center hot
    • TPS 65950 POWER SUPPLYThe TPS2141 has an integrated 3.3V LDO which is being used to supply the 3.3V as required on the BeagleBoard for the DVI-D interface and the UART CALLED WALL SUPPLY.•  When the DC supply is plugged in, the switch is disabled because the Ground Is removed from tps 2141.• TPS 65950 FUNCTIONS o Main Core Voltages• o Peripheral Voltages• o Power Sequencing• o Reset• o Current measurement via SW
    • TPS 65950 P.S o VDD_PLL2• o VDD_PLL1• o VDAC_1V8• o VDD_SIM• o VMMC1• o VAUX2• IT AS TWO REGULATORS VDD1&VDD2.THOSE ARE CONTROLLED THROUGH THE “SMART REFLEX COMPLAINT VOLTAGE.”• IT AS TWO MODES VDD1&VDD2.THESE ARE CONTROLLE THROUGH THE SOFTWARE.
    • POP MEMORY a MCP (Multi Chip Package) that contains both the SDRAM andNAND Flash.IT IS MULTI CHIP PACKAGE.
    • SD/MMC CARDS. The SD/MMC connector is supplied power from the TPS65950 using the VMMC1 rail  When a card is inserted into the SD/MMC connector, the Card Detect pin is grounded. This is detected on pin P12 of the TPS65950. An interrupt, if enabled, is sent to the OMAP3530 via the interrupt pin If an SD card is inserted into the SD/MMC connector and the write protect pin is active, the Write Detect pin is grounded
    • S-VIDEO CABLEAn S-Video cable can be connected to the BeagleBoard andfrom there is can be connected to a TV or monitor that supportsan S-Video input.IT SUPPORTS NTSC AN PAL FORMAT.NTSC MEANS “NATIONAL TELIVISION SYSTEM COMMITEE”.PAL MEANSIt can be changed via the Software.
    • DIFFERENCE BETWEEN NTSC AND PAL:• NTSC IT USES THE
    • MCBSPMcBSP2The multi-channel buffered serial port (McBSP) McBSP2 provides a full-duplex directserial interface between the OMAP3530 and the audio CODEC in the TPS65950
    • MCBSP1McBSP1McBSP1 provides a full-duplex direct serial interface between the OMAP3530 andthe expansion interface. There are 6 signals supported on McBSP1.
    • MCBSP3McBSP3 provides a full-duplex direct serial interface between the OMAP3530 and theEXPANSION INTERFACE.
    • DVI-D CABLEIn order to connect the DVI-D output to a monitor, aHDMI to DVI-D cable is required.This cable is not suppliedwith BeagleBoard but can be obtained through numeroussource.

    • RS 232 HEADER:-In order to access the serial port of the BeagleBoard a flat cable isrequired to connect to a PC. The adapter will not plug directly into thePC and will require an external Female to Female twisted cable (NullModem) in order to connect it to the PC. The ribbon cableis not supplied with the BeagleBoard but can be obtained fromnumerous sources.
    • AUDIO CABLES:A 3.5mm standard stereo output audio jack is providedto access the stereo output of the onboard audio CODEC.The Audio CODEC is provided by the TPS65950.A 3.5mm standard stereo audio input jack isprovided to access the stereo output of theonboard audio Codec.
