c6748仿真时上电后运行出现C674X_0: Trouble Reading Memory Block at 0xc0175b30 on Page 0 of Length 0x4和C674X_0: Trouble Halting Target CPU: (Error -1060 @ 0x0) 两个错误提示

控制台具体信息：

C674X_0: Trouble Reading Memory Block at 0xc0175b30 on Page 0 of Length 0x4: (Error -1060 @ 0xC0175B30) Device is not responding to the request. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.507.0)

C674X_0: Trouble Halting Target CPU: (Error -1060 @ 0x0) Device is not responding to the request. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.507.0)

请问这是什么原因导致的，PLL1配置超频？还是某个内存区溢出？

Shine：

0xc0175b30这块是DDR2的地址，在访问DDR2之前，对DDR2有进行初始化配置吗？
