VIPER Technical Manual

Getting started

 

 

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 Detailed242H hardware description, page 18243H.

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 PL438H– COMS ports, page 89244H, 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.
