求助 6678仿真器挂不上



大家好,

       芯片型号:TMS320C6678CYP  YB20-39ZC8X9  2010 TI 2 CYP G1       

      新板子,有两个6678(非菊花链方式连接,各自有各自的仿真器接口),仿真器挂不上,两个芯片现象是一样的!提示:

      C66xx_0: Error connecting to the target: (Error -1144 @ 0x0) Device core is hung. The debugger attempted to recover debug control, but was unsuccessful. Power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.520.0)

    调试过程:

    1、各个电压时正常的、上电顺序基本可以确定正确。(以前调过2-3个板子)

    2、时钟输入也正确,实际测量 SYSCLKOUT  为16.6M。(外部输入时钟为100M)

    3、复位状态输出为高 RESETSTATz = 1。

     4、仿真器的线路连接是正确的。

     上述的情况第一次遇见,且两个芯片状态一样,应该是共性问题!调了好长时间,实在没有头绪!麻烦大家看看,有没有遇到同样的问题,请指点解决方法!

谢谢!
