Introduction

The Jacinto7 EVMs are development and evaluation systems that enable developers to write software and develop hardware around the Jacinto7 family of processors. The main elements of the system are available on the base board(s) of the EVM. This gives developers the basic resources needed for most general-purpose type projects that encompass the Jacinto7 processor.

The Jacinto7 EVM is comprised of two boards:

  • Jacinto7 System on Module (SOM) – which includes Jacinto7 processor, its power solution, and non-volatile memory.
  • Jacinto7 Common Processor Board (CPB) – which includes wide variety of memories, peripherals, and debug tools supporting by the Jacinto7 processor.

Beyond the basic resources provided, additional functionality can be added via expansion cards.

This technical user's guide describes the hardware architecture and functionality of the Gateway/Ethernet Switch/Industrial (GESI) expansion board.
