+
+打开 SDDiskTool 的可执行文件 SD_Firmware_Tool.exe，插入 SD 卡。
+

+
+可移动磁盘设备选择要烧录的 SD 卡，功能模式选择 **SD 启动**，升级固件要是 RK 格式的完整镜像，最后点击**开始创建**烧录镜像。

+
+烧录过程请耐心等待，镜像分区很多，如果镜像很大，烧录时间会较长。

+SDDiskTool is Rockchip's official SD card flashing tool.
+
+## 1.Download SDDiskTool
+
+SDDiskTool currently only has a Windows version, so please use it on a Windows computer.
+
+Download link:[SDDiskTool_en_v1.74.zip](https://dl.radxa.com/tools/windows/SDDiskTool_en_v1.74.zip)
+
+## 2.Flash SD card
+
+We need to flash the corresponding complete image in RK format.
+
+Complete image in RK format refers to **The `update.img` image compiled using a series of Linux SDKs released by Rockchip based on Buildroot**
+
+Open the executable file `SD_Firmware_Tool.exe` of SDDiskTool and insert the SD card.
+
+:::warning
+When multiple storage devices are connected, please ensure you select the correct SD card to flash, otherwise other storage devices may be overwritten.
+:::
+
+Select the SD card to flash from the removable disk devices, choose **SD Boot** as the function mode, ensure that the firmware upgrade is a complete image in RK format, and finally click **Create** to flash the image.
+
+<img

+  style={{ width: "80" }}
+/>
+
+Please be patient during the flashing process. The image contains many partitions, and if the image is large, the flashing time will be longer.
