2.6 Booting VxWorks<br />

Once you have correctly configured your host software and target hardware,<br />

establish a terminal connection from your host to the target, using the serial port<br />

that connects the two systems. 4 For example, the following command starts a tip<br />

session for the second serial port at 9600 bps:<br />

% tip /dev/ttyb -9600<br />

See your BSP documentation for information about the bps rate<br />

(Help>Manuals contents>BSP Reference in the <strong>Tornado</strong> Launcher, or see the file<br />

wind/docs/BSP_Reference.html).<br />

You are now ready to turn on the target system power and boot VxWorks.<br />

2.6.1 Default Boot Process<br />

When you boot VxWorks with the default boot program (from ROM, diskette, or<br />

other medium), you must use the VxWorks command line to provide the boot<br />

program with information that allows it to find the VxWorks image on the host and<br />

load it onto the target. The default boot program is designed for a networked<br />

target, and needs to have the correct host and target network addresses, the full<br />

path and name of the file to be booted, the user name, and so on. 5<br />

When you power on the target hardware (and each time you reset it), the target<br />

system executes the boot program from ROM; during the boot process, the target<br />

uses its serial port to communicate with your terminal or workstation. The boot<br />

4. Commonly available terminal emulators are tip, cu, and kermit; consult your host reference<br />

documentation.<br />

5. Unless your target CPU has nonvolatile RAM (NVRAM), you will eventually find it useful<br />

to build a new version of the boot loader that includes all parameters required for booting<br />

a VxWorks image (see 4.7 Configuring and Building a VxWorks Boot Program, p.144). In the<br />

course of your developing an application, you will also build bootable applications (see<br />

4.4 Creating a Bootable Application, p.127).<br />
