Unless your target has a color display system supported by its BSP,
VxWorks doesn't have text color. I suspect you mean Tornado rather
than VxWorks.

Check the index entry for "color" in the Tornado User's Guide.

Dear Michael...

I don't want to change font color in tornado.. I want to change
text color in target system. Where to verify whether my BSP is
supporting different text color or not?

OK, let's back up a step here. What display is it that you're want to
control. Does your target have some kind of display integral to that
target, such as an LCD or similar? Or, as is far more typical in an
embedded system, are you using a terminal or terminal emulator connected
to one of the target's serial ports?

Consider my simple example...

void Display()
{
printf("\n Welcome to comp.os.vxworks");
}

After compiling this code , I am downloding this object file
("Display.o") to my target system using
following command.

-> ld -> Display

whats my aim is that i want to display string "Welcome to
comp.os.vxworks" in green color.

I think u got doubt...

its possible.

in vxworks we can access video ram memory locations directly. use
commands like
d - to display
m- to modify
in your target shell(provided you should have a seperate monitor or a
lcd display for the target. this wont be reflected in the
hyperterminal)

find the appropriate colour (means appr memory location) and in your
program modify those location.

I had done this long before in one of my project.

regards

"-> " indicates that you're using the shell and, unless you have redirected
standard I/O, the shell is probably using the console serial port fo its I/O.
If all of this is true, then the result of your printf is being transmitted
to a terminal or terminal emulator and the technique you might use to change
the colors depends entirely on the capabilites of that terminal or terminal
emulator.

Try changing your routine to this,

void Display()
{
printf("\n \x27[32mWelcome to comp.os.vxworks\x27[0m");
}

vxWorks FAQ, "http://www.xs4all.nl/~borkhuis/vxworks/vxworks.html"

This is not a vxWorks question, it is a hardware question.

Why don't you describe your hardware environment a little better.
Then, go to the appropriate newsgroup and ask the question again.

For example, there are ANSI control characters to do this if your
display is from a serial port to a serial terminal.

And as others have mentioned, there are VGA programming methods as well.

In either case, there is no standard vxWorks means of accomplishing this
goal.
