TMS320C6678: 使用NIMU helloWorld例程，发送超时

bh t

Part Number: TMS320C6678

型号：TMDSEVM6678LE 开发板

环境：CCS 9.3.0.00012, C667x PDK 2.0.16, NDK 3.61.1.01, SYS/BIOS 6.76.3.01

问题描述：

1. 根据https://www.ti.com/lit/an/sprac57/sprac57.pdf中的第四节“How to run Processor SDK Based NDK Examples on C6678 and C6657 KeyStone I Devices”创建工程，开发板上SW9 User Switch2开关设置为OFF(Static IP)

2. helloWorld中302行if(0)更改为if(1)，设置IP和MAC地址：
