Mega 2560 won't upload

I have a Mega 2560. The green light is on and the yellow light at D13 flashes non-stop. I have compiled a simple code to flash an LED on D11. It Compiles fine and indicates it is complete. Though the Mega 2560 doesn’t change its code. Any idea why it isn’t communicating?

You seriously couldn't think of any more details that might be pertinent here? Like the output from the IDE? Or how the Mega is connected? Or what the code is that you're trying to load? Or what version of the IDE? Or what OS? Nope, all you're going to tell us is that it doesn't work and then you want to know why. See the problem there?

That's one step. Did you also upload the compiled code? See further above reply.
