To burn image files, perform the following steps:
1 Switch to the "Burn eMMC" tab, as shown in Figure 5-1.
Figure 5-1 Burning image files to the eMMC
2 Select a serial port for connecting the board, select the network IP address of the PC, and set the MAC address, IP address, subnet mask, and gateway to the board. See Figure 5-2.
The server IP address of the PC and the IP address of the board must be on the same network segment. Otherwise, image files fail to be burnt.
-
When the Fastboot started for the first time, the parameter settings will be automatically created. That is default settings.
While settings change, the new value will be automatically stored in the HiTool. When the fastboot starts next time, the last parameter settings are automatically loaded.
But, if the Hitool exits abnormally, the last parameter settings may not be stored successfully.
-
You can click "Save" button to save current network settings for the device, and you can click "Load" button to select a settings from stored history as current settings.
-
Switch "Use XML's parent path as default" state, if checked, search partition files under the XML's container, otherwise, search partition files using absolute path set in XML.
- Switch "Create eMMC partition table" selected state, the decision as to whether the Ext3/4 file system partition to create an eMMC partition table, the default is checked.
3 Click "Browse" to select a partition table to load it to the partition table, as shown in Figure 5-3.

If the image files of all partitions are packaged as an image file, the image file must be placed in the fastboot partition and the image file must contain the fastboot. In this case, the image file is burnt over a serial port. Therefore, it takes a long time to burn the image file. Note that a partition table must be created for the eMMC file system partition and therefore the image files of the eMMC partition cannot be packaged with images files of other partitions.
4 Select Create eMMC partition table. This ensures that an eMMC partition table is created for the Ext3/4 file system partition.
- As the eMMC uses the DOS partition, the kernel can identify the Ex3/4 file system partition only when a partition table is created for the Ex3/4 file system partition.
- If the partitions of the eMMC change, you must select Create eMMC partition table to create an eMMC partition table again. Otherwise, the kernel cannot identify the Ex3/4 partition.
To modify information about a partition, modify the .xml partition information files or click the corresponding partition row in the fastboot, as showed in Figure 5-4.
Figure 5-4 Modifying the partition information
The details are as follows:
- To add a partition row, click
. After clicking a partition row, you can rename the
partition, select the required file system, select the file system type, and change the start
size of the partition and partition size. - The start size of a partition and partition size are in the unit of KB or MB and must be an integral multiple of the eMMC sector size. Otherwise, an error may occur.
- To select the file to be burnt to a partition, click
. - To delete a partition, click
. Note that the fastboot partition cannot be deleted and the
name of the fastboot partition cannot be changed. Otherwise, the images files fail to be
burnt in one-click mode. - To select all partitions for burning all files in one-click mode, click
; to deselect all
partitions, click again. To select a specific partition, select the corresponding check 
box .
Users can click 
button to save the partition table to a file.
-
There is no .xml partition information files when the fastboot is started for the first time. When you
close the fastboot after setting or modifying the partition information, a dialog box shown in Figure
5-5 is displayed, asking you whether to save the partition information. Click Yes. The Save As dialog
box shown in Figure 5-7 is displayed. Select a save path, enter a file name, and click Save. An .xml
partition information file is generated. If you click No,the tool will close without save
the partition information.Click cancels, neither tool closed nor partition information saved.When you change the perspective, dialog box showed in Figure
5-6 is displayed, asking you whether to save the partition information. Click Yes. The Save As dialog
box shown in Figure 5-7 is displayed. Select a save path, enter a file name, and click Save. An .xml
partition information file is generated. Click No, the partition information will not be saved. The file must be in .xml format. Otherwise, the partition information cannot be loaded at the next startup.

5 Connect the serial port and Ethernet port of the board. If the board is powered on, power it off and short-circuit the bootstrap jumper cap of the board. For details, see chapter 1 "Preparing the Burning Environment"
6
Click 
to start to burn files, see Figure 5-8.
7 Power on the board to burn the files. Figure 5-9 shows the burning process.
The information about the burning process is displayed in the Console box.
If an error occurs:
- Check whether correct serial port is selected.
- Check whether the correct Ethernet port is selected.
- Check whether the bootstrap jumper on the board is short-circuited.
The uploading process is similar to the burning process.
8 Connect the serial port tool and restart the board.
