dpaView - manipulate DPA ports

SYNOPSIS

DPA test and configuration tool

DESCRIPTION

The dpaView utility is a (bash) script-based utility that provides a control and status interface to DPA hardware. dpaView exposes several layers of status and control information, allowing the user to perform a range of tasks from setting register bits to initializing all installed DPAs using a few commands. The utility is implemented as a thin shell wrapper, allowing the user to execute shell commands from within dpaView, and to place instructions in a text file and use them as input for batch operations. As a shell script, it may be used in a minimal environment, and is easily modified without special tools.

dpaView provides built in help for the commands; (type 'help') at the prompt for assistance.

ENVIRONMENT

dpaView is intended for use on a sideArm board, connected to DPAs via a backplane. The following components must be on the sidearm:
• sa1110spi kernel module must be installed
• sa1110gpio c. kernel module must be installed
• bash shell
• A text editor is optional (for creating script files)
