2812始终不运行

您好，我是刚刚接触TI的产品，使用的是2812，我的CPU系统是做过PCB板的，程序过程中的运行环境为CCS3.3，遇到情况是：

程序通过JTAG口进行仿真烧写到内置RAM中时，经过load program后，绿箭头指在 3FFC00 28AD MOV     @SP,#0x0400 上，但运行程序后经过run和halt后绿箭头始终停留在这句话上。请问是怎么回事？

PS:该程序在2812开发板上运行正常

    Load基于RAM的程序到片上运行，需确定你的.cmd文件是配置到RAM，之后进行load program --> reset --> restart --> go main --> run.

    楼主用下面的例程试试吧：

    resetCPU时，Error connecting to the target: Error 0x00000204/-1147 Error during: Register, OCS,  It appears that the target is being held in reset.  If this is a multi-core system, the master CPU may not be releasing the DSP from reset.  Please check your configuration in CCSetup and/or your GEL file to ensure that nothing is blocking the DSP from being released from reset   Sequence ID: 0 Error Code: -1147 Error Class: 0x00000204
