Getting Started The Development Kit contains a Quickstart Manual to enable users to set-up and start using the board. Please read this manual and follow the steps defining the set-up of the board. Once you have completed this task you will have a working VIPER system and can start adding further peripherals enabling development to begin. The section below has been designed as a guide to the set-up and use of some of the features of the VIPER. If you would like more detailed information on any aspect of the board refer to the “Detailed Hardware Description” section of this manual.

Using the VIPER The VIPER uses the RedBoot bootloader (Red Hat Embedded Debug and Bootstrap firmware) to provide initial boot strapping for the board. The bootloader has many features including: Downloading and execution of embedded operating systems via a serial port (X or Y modem), or Ethernet (support for BOOTP and TFTP). Interactive command line interface allows management of Flash images, downloads and general configurations. RedBoot only has limited support for the VIPER hardware (Ethernet, Serial, Flash, SDRAM), to use any other hardware function an operating system and appropriate drivers must be running. Connecting a Host PC to the VIPER Console (COM1) RedBoot does not support the flat panel controller, therefore by default the console is directed to COM1. To view this you will need a null modem cable, which is supplied in the Development Kit and a computer with a suitable terminal emulator. Connect one end of the null modem cable to the VIPER’s COM1 and the other to your computer. Set the terminal emulator as follows: Baud Rate: 115200 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None Plug the power supply into the VIPER. You should now see the following in your terminal emulator window: Ethernet eth0: MAC address 00:80:66:10:00:01 IP: 10.2.28.4/255.255.0.0, Gateway: 10.2.1.1 Default server: 10.2.28.2, DNS server IP: 0.0.0.0 RedBoot(tm) bootstrap and debug environment [ROM] Non-certified release, version @CURRENT@ for VIPER - built 11:40:34, Apr 16 2003 Platform: VIPER (XScale PXA255) Copyright (C) 2000, 2001, 2002, Red Hat, Inc.

Using the CompactFlash™ Socket The VIPER is fitted with a Type II CompactFlash socket mounted on the topside of the board. This socket is connected to Slot 0 of the PXA255 PC Card interface. The socket supports both Type I and Type II CompactFlash cards, for both memory and IO. The VIPER supports hot swap changeover of the cards and notification of card insertion. The CompactFlash card can only be inserted into the socket one way. The correct orientation is for the top of the card i.e. the normal printed side to be face down to the PCB. RedBoot does not support the CompactFlash interface, so a suitable operating system such as Arcom Embedded Linux (AEL) port or Windows CE .NET, will need to be installed to support this function. Using the Serial Interfaces (RS232) The five serial port interfaces on the VIPER are fully 16550 compatible. Connection to the serial ports is made via a 40-way boxed header. The pin assignment of these headers has been arranged to enable a 9-way IDC D-Sub plug to be connected directly to the cable. The D-Sub connector will be compatible with the standard 9-way connector on a desktop computer. A suitable cable is provided as part of the Development Kit. Using the Audio Features There are four audio interfaces supported on the VIPER, Amp out, Line out, Line in and Microphone. The Line In, Line Out and Amp interfaces support stereo signals and the Microphone provides a Mono input. The amplified output is suitable for direct drive of any 4-8Ω load with a maximum power output of 2mW per channel. Connections are routed to a 12-way header PL6. The relevant signals for each interface are shown in the table below: Function Pin No. Signal

Using the PC/104 Expansion Bus PC/104 modules can be used with the VIPER to add extra functionality to the system. This interface supports 8/16 bit ISA bus style peripherals. Arcom has a wide range of PC/104 modules which are compatible with the VIPER, these include modules for digital I/O, analog I/O, motion control, video capture, CAN bus, serial interfaces etc. Please contact the Arcom sales team if a particular interface you require does not appear to be available as these modules are in continuous development. In order to use a PC/104 board with the VIPER it should be plugged into PL11 for 8-bit cards and PL11/PL12 for 8/16-bit cards. Before powering up the system, check that the jumper settings on the card for I/O address and IRQ settings do not conflict with any devices on the VIPER. The ISA interface on the VIPER does not support DMA. Please refer to the Interrupt Assignment section of this manual fort PC/104 interrupts use. If a PC/104 card that requires +5V is used, this will automatically be supplied via the PC/104 header. If +12V required this will only be available if the +12V pin on the ‘POWER’ connector PL16 has been connected to a supply. If –12V or –5V are required, these must be supplied directly to the PC/104 add-on board. The VIPER is available with non-stackthrough connectors by special order. Contact the Arcom sales for more details. Using the USB Ports The standard USB connector is a 4-way socket, which provides power and data signals to the USB peripheral. The 10-way header PL7 has been designed to be compatible with PC expansion brackets that support two USB sockets ( please refer to the USB section in this manual and Appendix A for further details). Using the Ethernet Interface The SMSC LAN91C111 10/100baseTx Ethernet controller is configured by the RedBoot bootloader. Connection is made via the 8-way header PL1. A second connector PL2 provides outputs that can be used to control LED's for Activity and Link status (refer to Appendix A for pin out details of this connector).

Detailed Hardware Description The following section provides a detailed description of the functions provided by the VIPER. This information may be required during development after you have started adding extra peripherals or are starting to use some of the embedded features. Processor The PXA255 is a low power ARM (version 5TE) instruction set compliant RISC processor. The PXA255 does not include a floating-point unit, however, the device contains a DSP co-processor to enhance multimedia applications. The 400MHz PXA255 is driven by a 3.6864 MHz clock, which is then used to generate all the high-speed clocks within the device. The processor has two supply inputs: the core is powered from a +0.8 – 1.3V source and the I/O is powered from +3.3V. These voltages are generated on the VIPER from the main +5V supply input. The PXA255 provides a Synchronous DRAM controller, 16-bit flat panel interface, AC97 interface, PC card / CompactFlash interface and a USB client controller. The PXA255 processor is packaged in 256 ball PBGA, and therefore is attached to the board during the assembly process. The PXA255 processor is a low power device so a heat sink is not required to support ambient temperatures up to 70°C (85°C for the industrial variant). Memory The VIPER includes four types of memory device, the synchronous DRAM system memory, 1MByte bootloader EPROM, the resident Flash array and 256KBytes of SRAM. Synchronous DRAM Interface There are two memory configurations supported by the VIPER, these are 16Mbyte and 64MByte of SDRAM. These are surface mount devices soldered to the board and cannot be upgraded. Regardless of the variant, all of the SDRAM is located in DRAM BANK 0. RedBoot automatically detects the amount of memory fitted to the board, and configures the SDRAM controller accordingly. The SDRAM controller supports running the memory at frequencies between 50MHz and 100MHz, this can be configured to achieve the optimum balance between power consumption and performance.

Page 16

2192-12132-000-000

Bootloader EPROM A 1MByte Flash EPROM device is used as the boot ROM and serves as a location for RedBoot and configuration information. Flash Memory/Silicon Disk The VIPER supports up to 16MByte Flash memory, using the PXA255 CS1 to access the devices, the Flash is located at address 0x04000000. The Flash status LED will illuminate whenever the Flash drive is accessed. The Flash memory ‘busy’ status output can be read from I/O line GP14 of the PXA255, this can be used to generate an interrupt to indicate the completion of a CFI (Common Flash Interface) command. Static RAM The VIPER is designed to support a 256KByte static RAM device. The static RAM device can be backed up from an off board battery when the main supply is removed, therefore data will be non-volatile. The SRAM uses the PXA255 CS5 to access the device, and is offset by 8MByte in the chip select; (located at 0x1480 0000). Memory Map The following table shows the memory map for the VIPER.

Graphics Controller The Intel PXA255 processor contains a 16-bit flat panel display controller and provides an interface capable of driving passive (STN) or active (TFT) flat panel displays. A full explanation of the graphics controller operation can be found in the PXA255 data sheets included on the support CD. The flat panel data and control signals are routed to a 40-way high-density connector (PL3). The flat panel interface can be configured to drive a variety of panel types. The part number for the flat panel interface connector is: Oupiin 3214-40RB The mating connector is part number: Oupiin 1203-40GB The VIPER-FPIF is available which allows the user to easily wire-up a new panel using pin and crimp style connectors. The following tables provide a cross-reference between the flat panel output signals and their function when configured for different displays.

Below is a table covering the clock signals required for passive and active type displays:

VIPER Pin Active Display Signal (TFT)

Passive Display Signal (STN)

PCLK Clock Pixel Clock LCLK Horizontal Sync Line Clock FCLK Vertical Sync Frame Clock BIAS DE (Data Enable) Bias

The display signals are +3.3V compatible; the VIPER contains power control circuitry for the flat panel logic supply and backlight supply. The flat panel can be supplied with a switched 3.3V supply while the backlight can be supplied with a switched 5V supply. As there is no on-board protection for these switched supplies, care should be taken not to draw too much current (Refer to the Power Supply section for details). Care must be taken during power up/down to ensure the panel is not damaged due to the input signals being incorrectly configured. Typically the power up and power down sequence is as follows, please check the datasheet for the particular panel in use. Power Up:

1. Enable Display VCC 2. Enable Flat panel interface 3. Enable Backlight

Power Down is in reverse order.

The following PXA255 GP lines are used for LCD functions. PXA255 GP Function GP9 Backlight Enable GP10 LCD Vcc Enable GP16 (PWM0) Backlight brightness control Backlight Enable This controls the switched backlight supply voltage. When the GP9 is set to a logic high the backlight supply is turned on BLKSAFE (PL3 – Pin 2). The BLKEN signal on PL3 (pin 1) is the un-buffered GP9 signal. LCD Vcc Enable This controls the switched LCD supply voltage when the GP10 is set to a logic high the LCD supply is turned on LCDSAFE (PL3 – Pin 6). The default LCD output supply is 3.3V. Note: This may be factory configured (using a surface mount resistor) to 5V. Backlight Brightness Control GP16 is available on PL3, pin 7. This can be used in one of two ways, dependant upon the type of backlight inverter being used. Some inverters have a ‘DIM’ function, a logic level to choose between two levels of intensity, if this is the case GP16 can be used to set this. Other inverters have an input suitable for a PWM (Pulse Width Modulation); in this case GP16 can be configured as PWM0. Interrupt Assignments Internal Interrupts For details on the PXA255 interrupt controller and internal peripheral interrupts please refer to the Intel PXA255 developer’s manual on the Development Kit CD. External Interrupts The following table lists the GP lines used for generating interrupts externally to the PXA255: PXA255 GP Peripheral GP0 Ethernet GP1 PC104 Interrupt Controller GP2 USB GP3 COM4 GP4 COM5 GP8 CompactFlash RDY/nBSY GP14 FLASH GP32 CompactFlash Card Detect PC104 Interrupts Any interrupt generated on the PC104 interface will generate an interrupt using GP1 in a level triggered mode. A register located at 0x30000000 will indicate which PC104 IRQ generated the interrupt. The register indicates the status of the interrupt lines at the time the register is read, the relevant bit is set to a 1.

Bits PC104 IRQ Bit 0 IRQ3 Bit 1 IRQ4 Bit 2 IRQ5 Bit 3 IRQ6 Bit 4 IRQ7 Bit 5 IRQ10 Bit 6 IRQ14 Bit 7 IRQ15 Writing a ‘1’ to a relevant bit will clear the interrupt. CompactFlash Slot 0 of the on chip PC Card controller is connected to the CompactFlash connector to create a hot swappable 3.3V interface. Start Address Region Name 0x2C00 0000 Socket 0 Common Memory Space 0x2800 0000 Socket 0 Attribute Memory Space 0x2400 0000 Reserved 0x2000 0000 Socket 0 I/O Space GP9 on the PXA255 is used to detect a card being inserted. Detecting a falling edge will indicate a CompactFlash card has been inserted. GP8 is used as the interrupt for the CompactFlash (RDY/nBSY). GP82 controls the power switch for the CompactFlash interface, setting this to logic high will enable the 3.3V supply to the connector. Real Time Clock The accuracy of the Real Time Clock is based on the operation of the 32.768KHz watch crystal. This will provide an accuracy of +/-1 minute per month if the board is in an ambient environment of +25OC. When the board is operated outside this temperature then the accuracy may be degraded. There are two RTC’s on the VIPER, one is contained within the PXA255 device, this is not battery backed, but is only used for power management events. A Dallas DS1307 RTC is used to keep time and date and can be battery backed using an external battery. The following PXA255 GP lines are used to control the DS1307 PXA255 GP Function GP84 Clk GP83 Data A data sheet for the Dallas RTC device is available on a Development Kit CD.

An external battery (+VBAT) can be to provide the battery backup for the Real Time Clock and the SRAM. The external battery will supply power to the battery backup circuit when there is no +5V supply to the board. The battery voltage must be in the range of 2.8V to 3.3V. Ethernet Controller An SMSC LAN91C111 Ethernet controller provides a 10/100-BaseTX interface. The device provides compliance with IEEE802.3u 100BASE-T specification and IEEE 802.3x Full-duplex Flow Control. A 93C46 EEPROM is used to store configuration data and MAC information. An 8-way 0.1” header (PL1) is used to provide signals (see Appendix A for pin assignment details). A second 6-way 2mm header (PL2) also provides the user with Activity and Link status LED signals. The output lines sink current when switched on therefore the anode of each LED should be connected to PL2’s pins 1,3 or 5 and the cathode to the appropriate status line. Sound The AC’97 interface on the PX255 processor along with a National Semiconductor LM4548 AC97 Audio CODEC is used to support Audio on the VIPER. Line In, Line Out and Microphone interfaces are generated. The Line Out is used to generate an amplified 200mW output, suitable for driving a 4-8Ω load. Connection is made via a 12-way 0.1” header PL6 (see Appendix A for pin assignments). Watchdog Timer The PXA255 contains an internal watchdog timer, which can be used to protect against erroneous software. Timeout periods can be adjusted from 271µs to 17s. The watchdog timer is disabled by a RESET. When a timeout occurs, the board will be reset. Please refer to either an Arcom operating system Technical Manual, or the PXA255 Developers Manual. User Configuration Jumpers There are two user configurable jumpers on the VIPER, LK2 and LK3. The status of these user jumpers can be read via GP5 and GP7 on the PXA255. If the jumper is inserted then the corresponding bit will be read as logic ‘0’ (see the “Jumpers and Connectors” section for further details). These jumpers do not have any defined function on the board; therefore can be used to select options in your application program. USB Interface There are two Universal Serial Bus (USB) interfaces on the VIPER. These interfaces have been designed to support the Open Host Controller Interface (OpenHCI). There are four signal lines associated with each USB channel, VBUS, DATA+, DATA- and GND.

Page 22

2192-12132-000-000

A USB power control switch is used to control the power and protect against short-circuit conditions.

If the USB voltage is short circuited or more than 500mA is drawn from either supply the switch will turn off the power supply and automatically protect the device and board. The VBUS signal is derived from the +5V supply via the VIPER. If you are require details for the USB bus, or would like to determine whether particular peripherals are available then please check the following Internet site www.usb.org. A factory fit option, changes USB port 1 from the host interface to a client. Please contact Arcom for more details. General Purpose I/O Eight general-purpose inputs and eight general-purpose output lines are provided on the VIPER. These lines are routed to a 20-way 2mm header PL9. The header provides buffered 5V tolerant signal. An output state of ‘1’ is driven to 3.3V. Inputs can be read from offset 0x50000 of CS5 (0x18050000). The following GP lines from the PXA255 processor can control the outputs: VIPER Outputs PXA255 GP D0 GP20 D1 GP21 D2 GP22 D3 GP23 D4 GP24 D5 GP25 D6 GP26 D7 GP27

Page 23

2192-12132-000-000

The PXA255 GP lines must be configured using the registers built into the device to ensure they function correctly. Various features can be programmed for each pin including direction control and alternate function. These are setup up by RedBoot by default. The general purpose inputs are 5V tolerant, while the outputs can sink and source up to 24mA @ 3.3V. PC/104 Interface The PC/104 interface supports 8/16 bit ISA bus style signals. Add on boards can be used to enhance the functionality of the main board. Arcom has an extensive range of PC/104 compliant modules and these can be used to quickly add digital I/O, analog I/O, serial ports, video capture devices, PC CARD interfaces etc. The ISA bus is based on the x86 architecture and is not normally associated with RISC processors. It will probably be necessary to modify standard drivers to support any 3rd party PC104 modules. Any PC/104 board plugged in will appear in the PC Card memory space (Socket 1, while the CompactFlash is Socket 0). Start Address Region Name 0x3C00 0000 Socket 1 PC/104 Memory Space 0x3400 0000 Reserved 0x3000 0000 Socket 1 PC/104 I/O Space The PC/104 bus signals are compatible with the ISA bus electrical timing definitions. DMA and bus mastering is not supported on VIPER’s PC/104 interface. For details on PC/104 Interrupts please refer to the Interrupt section of this manual. Serial Ports There are five high speed 16550 serial UART’s on the VIPER. All five channels are fully functionally compatible with the 16550 and can be used as standard RS232 serial interfaces. COM1 COM1 uses the Full Function UART in the PXA255 (FFUART). The port is buffered to RS232 levels, and supports full handshaking and modem control signals. COM2 COM2 uses the Bluetooth UART in the PXA255 (BTUART). The port is buffered to RS232 and supports RTS, CTS handshaking. COM3 COM3 uses the Standard UART. The port is buffered to RS232, but does not support any handshaking (Rx / Tx only). COM4 COM4 uses UART1 of the external 16C2852 device (See table below). COM5 COM5 uses UART2 of the external 16C2852 device (See table below).

The table shows the configuration for each channel.

RS422/485 Interfaces The COM5 serial interface can be used to support RS422 and RS485 interfaces. The default configuration has been selected to enable RS422 operation. RS422 The RS422 interface provides full-duplex communication. The signals available are TXA, TXB, RXA, RXB and Ground. The maximum cable length for an RS422 system is 4000ft (1200m) and supports 1 transmitter and up to 10 receivers. To enable RS422 operation LK8 should be removed and the RTS line from COM4 should be at logic ‘0’. LK9 and LK10 should be made if the board is at the end of the network. RS485 This is a half-duplex interface that provides combined TX and RX signals. PL14 pin 5 provides TXB/RXB and pin 6 provides TXA/RXA. A ground connection is also required for this interface. The maximum cable length for this interface is the same as RS422 (4000ft), but RS485 supports up to 32 transmitters and receivers on a single network. Only one transmitter should be switched on at a time. The VIPER uses the RTS signal to control transmission. When this signal is at logic ‘1’ the driver is switched off and data can be received from other devices. When the RTS line is at logic ‘0’ the driver is on. Any data that is transmitted from the VIPER will automatically be echoed back to the receiver. This enables the serial communications software to detect that all data has been sent and disable the transmitter when required. LK8 should be made to enable the RS485 interface. LK9 and LK10 provide parallel line termination resistors (these should ideally match the characteristic impedance of the transmission line) and should be made if the VIPER is at the end of the network. The UART used on the VIPER for COM5 has extended features including auto-RTS control for RS485. This forces the RTS signal to change state (and therefore the direction of the RS485 transceivers) when the last bit of a character has been sent onto the wire. Please refer to the XR16C2852 datasheet on the Development Kit CD. Each of the configurations are illustrated on the following page:

Power Supply The VIPER is designed to operate from a single +5V ± 5% (4.75V to +5.25V) supply. The power connector PL12 has a +12V connection defined, but is not required for the VIPER under normal operation. It can be used to supply +12V to the PC/104 stack if required. The power connector PL14 is part number: Molex 22-05-7048 The mating connector is part number: Molex 22-01-2045 Three other supply voltages are present on the board, these are 0.8 – 1.4V, 1.8V and +3.3V. These supplies are required for the CPU core and on-board devices. The +3.3V supply is routed to the CompactFlash interface, and can be used to power +3.3V flat panels via PL3. The +5V supply is monitored automatically on-board and if this supply falls below 4.63V the board will be placed in RESET. When the power supply rises above this threshold voltage the board will start to operate again. This power supply monitor will ensure that the board does not hang if the supply voltage fails at any point.

Power Management The VIPER board supports various power management functions. Processor The power manager in the PXA255 offers the ability to disable the clocks to the different internal peripherals. By default after reset all clocks are enabled. To reduce power consumption disable the clocks for any unused peripherals. Also the clock speed of the processor core, PXbus (the internal bus connecting the CPU core and the other blocks of the PXA255), LCD and SDRAM can be changed to achieve a balance between performance and power consumption. For more details on the internal power manager please refer to the PXA255 documentation on a Development Kit CD. UARTS COM4 and COM5 are generated from an external 16C2852 DUART. This device supports a sleep mode with an auto wake up. By enabling this feature the DUART will enter sleep mode when there are no interrupts pending. The part will resume normal operation when any of the following occurs: receive data start bit, change of state on: CTS, DSR, CD, RI or data is being loaded into transmit FIFO. If the part was awakened by one of the above conditions, it will return to the sleep mode automatically after the condition has cleared. Please refer to the 16C2852 datasheet on a Development Kit CD, or information on enabling the sleep mode. GP12 and GP13 on the PXA255 can be used to power down the RS232 drivers on the VIPER, to save power. The table shows the affect of GP12 and GP13 on the RS232 drivers, placing the drivers in shutdown mode offers the greatest power saving. GP12 GP13 Operation Status Transmitters Receivers

0 0 Normal Operation Active Active 0 1 Normal Operation Active High-Z 1 0 Shutdown High-Z High-Z

CompactFlash The power supply to the CompactFlash interface is controlled via software, and supports hot swap card insertion and CompactFlash power down states. GP82 on the PXA255 is used to control the power supply, setting this line low (logic 0) will switch off power to the CompactFlash interface. Ethernet The network interface supports a power down mode, which shuts down the internal MAC and PHY blocks of the network controller. Placing the controller into low power mode can reduce the power consumption of the VIPER by up to 700mW. USB The USB Host controller supports a power down mode. Placing the controller into power down mode can reduce the power consumption of the VIPER by up to 130mW. Audio The Audio interface supports the AC ’97 Low Power Modes, shutting down the digital interface can reduce consumption by up to 45mW and shutting down the analog interface can reduce consumption by 100mW. Status LED’s There is a single status LED on the VIPER. This indicates Flash access, accessing either the boot device or the main Flash array will result in the LED flashing. RESET Switch A momentary switch (Push to Make) may be connected on LK1. If the switch is pressed it will cause the board to be reset. All onboard devices will be reinitialised. This may be useful during development to restart the board after a software crash.
