我的系统中只有一块VC5402，各输入引脚都作了相应的上拉下拉处理，电源正常，时钟也正确。接上了仿真器后进CCS总提示下面的错误信息

，但换另外的板子则正常。请大虾指点一下。谢谢了！！！


CCS提示的出错信息:

can't initialize target cpu
error 0x80000240/-1073
fatal error during initialization, OCS
Bad target silicon revision number
please check your multi-processor configuration
The number of devices in the JTAG scan path
must be correct for the silicon revision to be read
or, you may have selected the wrong DSP device driver
