dsp csl_init调用卡死

需要手动加入库文件：C:/CCStudio_v3.1/C6000/csl/lib/cslDM642.lib

/*

* 功能：CSL中cache module和timer module的使用示例

* 说明： 需要手动加入库文件：C:/CCStudio_v3.1/C6000/csl/lib/cslDM642.lib，建议到TI网站下载最新的CSL库更新，否则有些模块可能会出问题

CSL:Chip Support Library 芯片支持库

BIOS: TI DSP的实时操作系统

基于TI的DSP芯片的应用程序分为两种：一般应用程序，和DSP/BIOS应用程序。为简化编程，TI提供了一套C的编程接口，它以API和宏的形式封装了TI的所有硬件模块，这套接口统称DSP/BIOS。DSP/BIOS包含以下模块：System（包含MEM，SYS对象），Instrumentation（包含LOG，STS对象），Scheduling（包含CLK，PRD,HWI,SWI等等对象），Synchronization（包含SEM，MBX，QUE等等对象），Input/Output（包含RTDX，HST等等对象），Chip Support Library（包含DMA，GPIO等等对象）。
