TMS320F28035: Flash_Verify(Flash_ptr,Buffer,Length,&FlashStatus);操作失败

在使用C2000Ware_5_04_00_00\libraries\flash_api\f2803x中例程时，运行到

// Verify the values programmed. The Program step itself does a verify
// as it goes. This verify is a 2nd verification that can be done.
Status = Flash_Verify(Flash_ptr,Buffer,Length,&FlashStatus);
if(Status != STATUS_SUCCESS)
{
Example_Error(Status);
}

处Status返回31

想请教一下各位大佬是咋回事
