3. Download the compiled source package to the client platform, decompress the package, and copy the files required for burning to the folder created in step 1.
For the Hi3516 development board, the files required for burning of the small system are as follows:
- LiteOS: **OHOS_Image.bin**, **rootfs_vfat.img**, and **userfs_vfat.img**
- Linux: **uImage_hi3516dv300_smp**, **rootfs_ext4.img**, **userfs_ext4.img**, and **userdata_ext4.img**
2. Burn the image files using HiTool.
1. Open HiTool.
2. Set up HiTool.
Set the transfer mode to USB and burning mode to eMMC (the storage medium of the development board is eMMC).
3. Click **Browse** and select the burning configuration file (for example, **L1_3516_linux.xml**) from the folder created in step 1.
4. After clicking the **Burn** button, press and hold the **Update** key next to the serial port on the development board, and remove and insert the USB cable.
After the burning starts, logs are displayed in the console area at the bottom of HiTool.
When the burning is complete, HiTool displays a dialog box indicating that the burning is successful.
5. Click **OK**.
3. Import startup parameters.
1. Use the terminal tool to enable the serial port.
2. Restart the development board by removing and inserting its power supply. Press **Enter** in the serial port terminal tool within 3 seconds.
If **hisilicon \#** is displayed on the terminal tool page, the serial port of the development board is connected.
3. Copy the following startup parameters in the serial port terminal tool and press **Enter** to complete the setup.
- The startup parameters for the small system using the LiteOS kernel are as follows:
