ESP8266 OTA升级错误的原因？

因为项目要求，无法使用官方的升级接口，所以自己写flash进行升级，但是遇到了问题

error magic!
first boot failed, reboot to try backup bin



一直是错误的，我是用C#写了一个上位机，分段读取bin文件，然后通过UDP发给esp8266，并且在写入完成后把数据读出来了
数据跟我发送的是一致的，但是还是无法启动，以下是我的升级代码

#define USER1 0x01000
#define USER2 0x81000 //0x101000

uint16 History_Pack = 0;
uint32 OTA_ADDR;

void OTA_upgrade(void)

   uint16 TotalPack,CurrentPack;
   uint16 Sector;
   uint16 Sector_count = 0,num = 0;
   uint8 bin = 0;
    //总包数
    TotalPack = (uint16)char_change_int( UDP_ReceiveBuff.Pack_data, 2, UDP_ReceiveBuff.Data_Length);
    //当前分包
    CurrentPack = (uint16)char_change_int( UDP_ReceiveBuff.Pack_data, 2, UDP_ReceiveBuff.Data_Length);
    //包长
    PackLength = (uint16)char_change_int( UDP_ReceiveBuff.Pack_data, 2, UDP_ReceiveBuff.Data_Length);

    os_printf("rn[OTA]TotalPack:%d CurrentPack:%d PackLength:%d",TotalPack,CurrentPack,PackLength);

    if (CurrentPack == 1 && TotalPack != 0)
    {
      //查询 user bin
      uint8_t userBin = system_upgrade_userbin_check();
      switch (userBin)
      {
      case UPGRADE_FW_BIN1:
            OTA_ADDR = USER2;
            Sector_count = 129;
            Sector = 130 + ((TotalPack * PackLength) / 4096);
         break; //  user2.bin
      case UPGRADE_FW_BIN2:
            OTA_ADDR = USER1;
            Sector_count = 1;
            Sector = 2 + ((TotalPack * PackLength) / 4096);
         break; // user1.bin
      default:  os_printf("[OTA]Invalid userbin number!n"); return;
      }
      while(1)
      {
         //擦除扇区（flash必须先擦再写）
         if(spi_flash_erase_sector (Sector_count) == SPI_FLASH_RESULT_OK)  
         {
            os_printf("rn[OTA]flash_erase_sector %d OKn",Sector_count);     
            num = 0;
            Sector_count++;   
         }else
          num++;
          if(num > 10 || Sector_count >= Sector)
             break;
      }      
    }

    if(History_Pack < CurrentPack && History_Pack != CurrentPack)
    {
      bin = OTA_Write((uint32 *)UDP_ReceiveBuff.Pack_data,PackLength);
      if(bin)os_printf("rn[OTA]write %d OK",CurrentPack);
    }
   else
      bin = 1;

   if(bin)
   {   
      
      //写入成功
      OTA_upgrade_Reply(TotalPack, CurrentPack, 1);
      History_Pack = CurrentPack;
   }
   else

测试的代码，写的有点乱，最开始打印写入的数据发现字节序反了，所以临时调换了一下
以下是程序打印的LOG
