When a platform is initially powered or a hard reset performed, the ABLE environment will be started, each component module will be loaded in turn. The last module loaded is the ABLE shell which will present the user with a command line interface.
ABLE has a flexible console system for its input and output
which can be configured to meet most requirements. The console
system is controlled with console command and the
console.read and
console.write parameters.
Details on using the console system can be found in Chapter 5, ABLE Console
The default console operation is to use all suitable input and output devices available.
On the EB2410ITX both the first serial port and the video display will be used for output and the serial port and USB keyboard for input.
In general use the console is used to interact with the ABLE Command Line Interface. This command line interface is generally assumed for most interactions with ABLE
Example 2.1. Display after starting ABLE on EB2410ITX
This example shows the typical default output shown when ABLE is started.
