还是FFT问题,这次找出问题的所在了,但不知道如何解决,求指导

通过上上个问题的解答,锁定到ICR寄存器上,通过配置该寄存器后,该寄存器的值为0x000e;但是Idle Status Register (ISTR) [0002h]这个寄存器的值还是0x020e;对应位置就是Hardware accelerator is disabled.                同时还存在一个问题,就是我用开发板查询IO口地址为0x1的值时,没有任何提示,但是使用自己做的板子后,再查询IO口地址为0x1的值时,出现了这样的错误:

C55xx: Trouble Reading Memory Block at 0x1 on Page 2 of Length 0x145: (Error -1069 @ 0x136) Device memory bus has an error and may be hung. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 6.0.14.5) 

不知道如何解决,求解答,谢谢了
