TI中文支持网HeapMemParams.shareAddr的类型在定义中为Ptr类型。
1.我的理解为该变量可以定义在shareregion中建立Heap的起始地址，这样理解对么？？
2.如果是这样理解话，我在XDC中定义的ShareMem的起始地址为0x00C00000。但是打断点显示为0x008002F8。这是为什么呢？？
3.我在C语言程序中定义了HeapMemParams.shareAddr=0x00C00000，但是编译报错，显示它是Ptr类型，无法用int值赋值，那该如何赋值呢？？
4.shareregionID和HeapMemParams.shareAddr之间的区别，是不是在XDC中定义了shareregion，再定义了regionID，就可以不用定义HeapMemParams.shareAddr?
尤其是两个Heap共用一个sharemem的情况。
谢谢能够帮我解答。
Andy Yin1：
你说的是在sysbios中使用HeapMem创建heap么？你使用的sysbios是什么版本？
关于heapMem有下面的结构体定义，我没有看到你说的shareAddr成员定义。
/* Params */struct ti_sysbios_heaps_HeapMem_Params { size_t __size; const void *__self; void *__fxns; xdc_runtime_IInstance_Params *instance; xdc_SizeT minBlockAlign; xdc_Ptr buf; xdc_runtime_Memory_Size size; xdc_runtime_IInstance_Params __iprms;};

你好。我在heapMem的头文件中找到这段的定义：
typedef struct HeapMemMP_Params { String name; /*!< Name of this instance. * * The name (if not NULL) must be unique among all HeapMemMP * instances in the entire system. When creating a new * heap, it is necessary to supply an instance name. * * The name does not have to be persistent. The supplied string is copied * into persistent memory. */ UInt16 regionId; /*!< Shared region ID * * The index corresponding to the shared region from which shared memory * will be allocated. */ /*! @cond */ Ptr sharedAddr; /*!< Physical address of the shared memory * * This value can be left as 'null' unless it is required to place the * heap at a specific location in shared memory. If sharedAddr is null, * then shared memory for a new instance will be allocated from the * heap belonging to the region identified by * #HeapMemMP_Params::regionId. */ /*! @endcond */ SizeT sharedBufSize; /*!< Size of shared buffer * * This is the size of the buffer to be used in the HeapMemMP instance. * The actual buffer size in the created instance might actually be less * than the value supplied in 'sharedBufSize' because of alignment * constraints. * * It is important to note that the total amount of shared memory required * for a HeapMemMP instance will be greater than the size supplied here. * Additional space will be consumed by shared instance attributes and * alignment-related padding. */ GateMP_Handle gate; /*!< GateMP used for critical region management of the shared memory * * Using the default value of NULL will result in use of the GateMP * system gate for context protection. */ } HeapMemMP_Params;
其中有Ptr sharedAddr的定义。但是我直接给它赋值0x0C000000，显示int型无法赋值给它。那我该如何处理呢？？
