PowerTAP调试ppc8248时，不能烧写flash;但用WireTAP时一切都ok！ ppc, PowerTAP, WireTAP, flash, 调试

处理器：ppc8248
Flash：AM29LV320DT
初始化文件不变，用WireTAP就可以进行烧写，没有任何问题。
用PowerTAP，connect可以成功，也可以读取Flash里面的内容都正确。但是Flash编程时，erase没有问题，显示sucess。而在blank test和Flash programm时，显示错误，错误原因是如下：
The Blank Check algorithm was interrupted during execution.
Please check if the flash base address is correct or if there are any
flash devices mapped inside the selected memory space.
If a custom target initialization file was used then check the following paramters:flash base address, flash bank size and flash bank port size.

请问：PowerTAP和WireTAP在初始化文件上有什么区别吗？
产生错误的原因可能是什么？
