TI 提供的C2000系列bootloader Demo的直接对FLASH进行操作

TI提供的bootloader的Demo是直接写FLASH，但是FLASH在写之前一定要先擦除啊，而且我做过实验直接指定一个FLASH地址，往这个地址里面写数据根本写不进去，往RAM中写数据是可以的。如下代码：void CopyData()
{

struct HEADER {
   Uint16 BlockSize;
   Uint32 DestAddr;
} BlockHeader;

Uint16 wordData;
Uint16 i;

// Get the size in words of the first block
BlockHeader.BlockSize = (*GetWordData)();

// While the block size is > 0 copy the data
// to the DestAddr.  There is no error checking
// as it is assumed the DestAddr is a valid
// memory location

while(BlockHeader.BlockSize != (Uint16)0x0000)
{
   BlockHeader.DestAddr = GetLongData();
   for(i = 1; i <= BlockHeader.BlockSize; i++)
   {
      wordData = (*GetWordData)();
      *(Uint16 *)BlockHeader.DestAddr++ = wordData;
   }

   // Get the size of the next block
   BlockHeader.BlockSize = (*GetWordData)();
}
return;
}

这样操作FLASH怎么会成功？？？不解
