TMS320F28386S: SCIA boot loader

We chose our GPIO pins wrong, rx=9, tx=84, which is not one of the pairs allowed. Thus I am trying to emulate what that code does. The serial flash programmer tries to download the flash kernel and SCI_Boot() receives it. After checking the keyword and stripping off the 16 reserved bytes CopyData() is called to receive the file. The file is sent in 11 blocks but what I do not understand is why all blocks have the same destination as there is no apparent processing between blocks.

BlockSize:2  destination:29184
BlockSize:24  destination:29184
BlockSize:1188  destination:29184
BlockSize:2  destination:29184
BlockSize:24  destination:29184
BlockSize:1188  destination:29184
BlockSize:307  destination:29184
BlockSize:4  destination:29184
BlockSize:4096  destination:29184
BlockSize:4096  destination:29184
BlockSize:1943  destination:29184

Here is the code from bootloader_shared_funcs.c

void CopyData(void)
{
    struct HEADER {
        uint32_t DestAddr;        
        uint16_t BlockSize;
    } BlockHeader;

    uint16_t wordData;
    uint16_t 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_t)0x0000U)
    {
        BlockHeader.DestAddr = GetLongData();
        
        // Added for debugging
        printf("\r\nBlockSize:%d  destination:%d", BlockHeader.BlockSize, BlockHeader.DestAddr);
        
        for(i = 1; i <= BlockHeader.BlockSize; i++)
        {
            wordData = (*GetWordData)();
            *(uint16_t *)BlockHeader.DestAddr = wordData;
            BlockHeader.DestAddr+=1U;
        }

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

    return;
