DSP外扩SDRAM写不进数据,谢谢

板子型号为TMS320VC5509,硬件仿真器为XDS510,在做外扩SDRAM的时候,写不进去数据。如果在main函数中初始化SDRAM处  EMIF_config(&emiffig);加上断点,则会出现如下错误,谢谢:

Trouble Reading Memory Block at 0x41b6 on Page 0 of Length 0x2c5:

Error 0x80000002/-1147

Fatal Error during: Memory, 

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: 65

Error Code: -1147

Error Class: 0x80000002

自已的板子?检查一下上电复位时序。
