QDTE is a GUI tool that is used for configuring the Device Tree Binary (DTB) files.
It can also be used to modify and configure [Interfaces](https://docs.qualcomm.com/doc/80-70015-4/topic/interfaces.html).
## About this task
For more details on QDTE features, see [QDTE](https://docs.qualcomm.com/doc/80-70015-4/topic/qdte-tools.html).
Set up
the configuration on your host device as follows:
Table : Configuration for Linux/Windows
| Property | File path for Linux/Windows host machine |
| --- | --- |
| SecTool path: Installation path to
SecToolsv2, a tool used to perform secure operations on software
images. | |
| Profile file: Used for signing the
security profile XML files. | |
| Sign cmd json: Used for signing the
JSON file from the QDTE installation directory. The test signing
mode is used for working on a nonsecure device. For secure
devices, see [enable secure
boot](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-11/enable-secure-boot.html). | |
| Devprg file: Device programmer
file. | |
| Flash type: Type of storage, which in
this case is UFS. | – |

Use the following procedure to configure the DTB files using QDTE. This procedure
is applicable only to XBL and UEFI DTB.
## Procedure
1. To open the XBLConfig ELF file, navigate to File > Open DTB Elf > From Build.
- If the file is invalid or corrupted, an error is generated. To prevent
the error, ensure that you download the valid boot binaries including
xbl\_config.elf, and use them with the XBL
configuration. The boot component is released in the binary and is part
of the firmware binary.
- If the file loads successfully, a tree view appears, populated with the
DTB elements.
2. To edit the XBLConfig ELF file, double-click it.
The file is displayed on the primary QDTE interface.
The figure shows
a XBLConfig helper window displaying the disassembled results of an
XBLConfig file containing two DTBs.
The figure shows an example file opened in a tree view with all four
columns populated:
3. To discard all the changes and reload the file from the disk (if the file
undergoes changes on the disk while the QDTE tool is open), select File > Reload File
4. To add items to the tree, right-click on a node. The following items are
displayed:
Table : DT items
| Tree item | Description |
| --- | --- |
| Add New Child | Adds a child in the tree. |
| Node | Asks for the name of the new node and adds it. If the
node name is invalid, an error occurs. |
| Property of Type | Opens a menu that allows you to choose the type of
property to add.
Adding a property displays the
Edit dialog box corresponding
to the type of the new property.
On confirmation,
a new property of the specified type is
added. |
You can remove all items in the DT, except for the root node. To delete an
item, right-click on it and select Delete. Deleting a
node also removes its child nodes, if any.
5. To edit a property, you can either right-click and select
Edit or double-click to open a dialog box. This
dialog box allows you to edit both the property name and value.
6. To view the DTB file as a binary hexadecimal dump, go to View > Raw, which displays the exported DTB file.
The following example of the raw view shows the offset, hexadecimal value,
and corresponding character columns, with a node highlighted in orange.
To remove all highlights, go to View > Clear Highlights.
7. To save the modified DTBs, you can either go to File > Save (or press CTRL + S)
to overwrite the existing file or go to File > Save Copy As (or press CTRL + SHIFT +
S) to save a copy of the DTB to a new file.
8. To generate a summary of the changes, select File > Export Change Report.
Creates a JSON file listing all changes made to the DT in the session, along
with the result of the DTB after the operation.
9. To save the modified DTB files within the main QDTE, navigate to the XBLConfig
helper window, and click Reassemble and Sign. Saves your
modified XBLConfig file.
10. Next, choose a name for the output file.
The XBLConfig toolchain is then invoked to re-assemble the ELF. If an
error message indicates that a signed XBLConfig was not generated, it is
downgraded to a warning, and a success message is shown instead.
