EVB7400
Chapter 1 Introduction
EVB7400 is a MLN7400 evaluation board and MCS-uClinux training kit that is suitable for code development and exploration of MN7400
with MCS-uClinux. It includes much of the hardware and software required completing your application development. It supports various
function related with network, communication such as IIC, SPI, UART, 10/100 Ethernet, multimedia module such as sound DAC, storage
media such as NAND FLASH memory module. Using the JTAG interface, you can debug the EVB7400 directly.
