Getting started
Depending on the development kit purchased, a Quickstart Manual is provided for
Windows CE, embedded Linux or VxWorks to enable users to set-up and start using
the board. Please read the relevant 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.
This section provides a guide to setting up and using of some of the features of the
VIPER. For more detailed information on any aspect of the board see
Using the VIPER
Using the CompactFLASH™ socket
The VIPER is fitted with a Type I/II CompactFLASH socket mounted on the topside of
the board. The socket is connected to Slot 0 of the PXA255 PC card interface. It
supports 3.3V Type I and II CompactFLASH cards for both memory and IO. The VIPER
supports hot swap changeover of the cards and notification of card insertion.
RedBoot supports ATA type CompactFlash cards. Files can be read providing the card
is formatted with an EXT2 file system. Eboot cannot boot from CompactFlash.
5V CompactFLASH is not supported.
The CompactFLASH card can only be inserted one way into the socket. The
correct orientation is for the top of the card, i.e. with the normal printed side
face down to the PCB.
Using the serial interfaces (RS232/422/485)
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 this header
has been arranged to enable 9-way IDC D-Sub plugs to be connected directly to the
cable. See the section
, for pin assignment and connector
details.
A suitable cable for COM1 is provided as part of the development kit. The D-Sub
connector on this cable is compatible with the standard 9-way connector on a desktop
computer.
COM4 (RS232) and COM5 (RS422/485) are not available on the standard
VIPER-Lite configuration. Eurotech Ltd can provide custom configurations
(subject to a minimum order quantity) for the VIPER-Lite populated with this
feature. Please contact our Sales team (see
) to discuss your requirements.
