Customizing the software

Ideally, the system you're designing will look identical to a supported evaluation platform. In reality, this isn't always the case, so you'll need to customize some of the components in that system.

As you can see, we've divided the source tree into three major branches: ipl, startup, and flash. Each branch consists of further subdirectories:
