ST-LINK V2/IAR not programming?

I'm trying to upload a ChibiOS demo to the STM32F3 Discovery board. The project builds fine under IAR and appears to connect & program correctly over the onboard ST-LINK. However, when I change the code (i.e. comment out everything, etc) , the board still seems to behave the same so I believe it's not really being programmed.

Is there something I have to do other than Project -> Download & Debug?

Both jumpers are on the ST-LINK/Discovery header.

Well you'll want to make sure you're targeting FLASH and not RAM. That you have not selected a simulated target. And the code is located at the base of FLASH, and not dependent on a Boot Loader.

You could also erase the flash.
