i m working on ARM9SAM9260 how to run code on keil micro vision 3 ? its showing target not created.
The only way to run code in uVision is in the Simulator: http://www.keil.com/support/man/docs/uv3/uv3_simulation.htm
"its showing target not created."
If the target was not created, then you don't have anything to run! This means that your build failed - look at the diagnostic messages, and fix the errors that they're telling you about!
It's sounds like you need to spend some time getting familiar with the tools before you continue with your project. Start here: http://www.keil.com/support/man/docs/uv3/uv3_examples.htm Work through those examples.
