如何查看该地址中的数据内容

嗨，我有一个PIC32 MZ启动套件上的APIC32 MZ2064 DAG169。我正试图查看内部DDR RAM（甚至1字节）的内容：我正在尝试使用内置的GLCD外围设备。MPLAB和谐配置器为我的示例项目生成了一个配置文件。像素缓冲器被放置在定义为GFXGLCDLayLe0SerBaseDADR 0xA800的X上，这似乎是正确的。因为0xA800是在KSGE1内存映射中的内部DDR RAM开始的虚拟地址，所以我调用PLIbGLCDGLayLayBaseAddiSrSSET（GLCDSIDID0，0，（UIT32 32×t）0xA8800），这基本上结束了当我查看T时使用KVAYToPaPA（0xA8800）设置SFR GLCDL0BADDR寄存器。他使用调试器包含0x08000兆**的SFR GLCDL0BADDR，这是内部DDR开始的物理地址，所以看起来正确。问题是，我如何查看该地址中的数据内容。我有一个变量UtiT32×T*BP（2）；**如果我将BP[0 ]设置为0xA8800或BP[0 ]到0x0800，调试器说它是一个无效的地址。我如何查看0xA8800的内容。是否需要编写一个函数来读取DDR中的数据，就好像它是外部的一样。我认为这是内存映射，并会显示任何其他部分的记忆。感谢在前进KNK53

    HI,

      I HAVE A PIC32MZ2064DAG169 ON A PIC32 MZ STARTER KIT.
I AM TRYING TO VIEW THE CONTENTS OF THE INTERNAL DDR RAM (EVEN 1 BYTE)

BACKGROUND:
    i AM TRYING TO USE THE BUILT IN GLCD PERIPHERAL.   
    THE MPLAB HARMONY CONFIGURATOR PRODUCED A CONFIG.H FILE FOR MY SAMPLE PROJECT.
    THE PIXEL BUFFER WAS PLACED AT
             #define  GFX_GLCD_LAYER0_BASEADDR                      0xA8000000

    THIS SEEMS CORRECT  ..  AS 0XA8000000 IS THE VIRTUAL ADDRESS OF THE BEGINNING OF THE INTERNAL DDR RAM IN THE MEMORY MAP FOR KSEG1

      THEN I CALL     
           PLIB_GLCD_LayerBaseAddressSet(GLCD_ID_0, 0, (uint32_t)0XA8000000);
      WHICH BASICALLY ENDS UP SETTING THE SFR GLCDL0BADDR REGISTER USING    KVA_TO_PA(0XA8000000)

     WHEN I VIEW THE SFR GLCDL0BADDR WITH THE DEBUGGER IT CONTAINS 0X08000000
       *** THIS IS THE PHYSICAL ADDRESS OF THE START OF THE INTERNAL DDR SO THAT SEEMS CORRECT.

     THE QUESTION IS HOW CAN I VIEW THE CONTENTS OF THE DATA AT THAT ADDRESS.
i HAVE A VARIABLE            
                   uint32_t *bp[2];

***  IF I SET BP[0] TO EITHER 0XA8000000  OR BP[0] TO 0X08000000 THE DEBUGGER SAYS IT IS AN INVALID ADDRESS.

HOW CAN I VIEW THE CONTENTS OF 0XA8000000.   

DO I NEED TO WRITE A FUNCTION TO READ DATA FROM THE DDR AS IF IT WAS EXTERNAL.   I THOUGHT IT WAS MEMORY MAPPED AND WOULD DISPLAY LIKE ANY OTHER SECTION OF MEMORY.

THANKS IN ADVANCE
