2 Constructing the Block Diagram

The first step in designing the hardware platform is to create a detailed block diagram. The block diagram should contain all major system ICs and illustrate which I/O ports are used for device interconnection. Below is a collection of resources to aid in the Block Diagram creation process.

• The AM335x Product folders (accessible from the AM335x Cortex-A8 Overview website) provide block diagrams, application reports, tools, software, design considerations, and other related information for various products under category "Related End Equipments".
• An Evaluation Module (EVM) is always a good source from which to start building a reference design for these devices. The AM335x Cortex-A8 Overview has links to TI hardware designs and EVMs based on AM335x. The technical documentation for these designs are available for download on ti.com.
• Select from a list of complementary devices to attach to the AM335x device in your system:
