# Tools The tools for the boot process include QDTE and Fastboot. QDTE is a GUI editor tool that can be accessed through the [Qualcomm Software Center](https://softwarecenter.qualcomm.com/#/) (QSC), whereas Fastboot is a diagnostic tool that offers a Recovery mode known as the Fastboot mode. For more information on QSC, see [Qualcomm Software Center User Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-72780-2/overview.html). > > > [QDTE](https://docs.qualcomm.com/doc/80-70017-4/topic/tools.html#qdte-tools) > > > QDTE is a tool used to configure the DTB by editing the `xbl_config.elf` file. > > > [Fastboot](https://docs.qualcomm.com/doc/80-70017-4/topic/tools.html#fastboot) > > > Fastboot allows you to flash software images such as the boot loader and helps in system recovery. > > > [Capsule generation in UEFI](https://docs.qualcomm.com/doc/80-70017-4/topic/tools.html#capsule-generation-in-uefi) > > > Capsule generation tools are specialized utilities designed to create capsule files, which are essential for performing firmware updates on various devices. > > > These tools streamline the process of packaging firmware updates into a format that can be deployed and applied to the device hardware. > > > The tools can be run on both Linux and Windows environments, providing flexibility for different development setups. > > > By using OpenSSL for certificate generation and signing, the tools ensure that the firmware updates are secure and authenticated. To set up the capsule see the [Capsule generation in UEFI](https://docs.qualcomm.com/doc/80-70017-4/topic/tools.html#capsule-generation-in-uefi). ## QDTE QDTE is a tool used to configure the DTB by editing the `xbl_config.elf` file. You can download QDTE from [QSC](https://softwarecenter.qualcomm.com/#/) and launch the UI using the command `./qdte`. QDTE offers the following features: - Allows for experimentation with configuration settings in a test environment. - Opens/reads a DTB file directly or parses an `xbl_config.elf` file and extracts the embedded DTB files. In the latter case, when the file is saved, the `xbl_config.elf` file is regenerated with signing. Do not use the QDTE tool to create the device tree source/device tree source inclusion (DTS/DTSI) files that represent the input source. Note QDTE v1.3.0 is supported on: > > > - Ubuntu 22.04 Linux host machines > - Windows 10 and 11 host machines For more information on how to configure QDTE, see [Configure](https://docs.qualcomm.com/doc/80-70017-4/topic/configure-qdte.html#configure-qdte). ## Fastboot Fastboot allows you to flash software images such as the boot loader and helps in system recovery. Fastboot is supported on Linux and Windows host machines. To enter Fastboot mode, you can use a hotkey for Fastboot. ### Fastboot using hotkey After powering on the device, press **VOL-**. The figure shows the Fastboot logs from the device entering the Fastboot mode.

Boots up the OS. | ### Recovery with Fastboot Fastboot serves as a recovery solution when the systemd-boot image and ESP are corrupted. The systemd-boot image boots from the EFI system partition (ESP). In such cases, Fastboot automatically initiates as a recovery option, allowing you to reflash the ESP. ## Capsule generation in UEFI The capsule generation tools are specialized utilities designed to create capsule files, which are essential for performing firmware updates on various devices. These tools streamline the process of packaging firmware updates into a format that can be deployed and applied to the device hardware. The tools can be run on both Linux and Windows environments, providing flexibility for different development setups. By using OpenSSL for certificate generation and signing, the tools ensure that the firmware updates are secure and authenticated. **Pre-requisites to run the tool** Before starting the capsule generation process, you need to generate the following certifications: - Capsule generation scripts are available at: [https://github.com/quic/cbsp-boot-utilities/tree/ba1ea8d0fdb24857553730aa247eb602c7b589ba/uefi_capsule_generation](https://github.com/quic/cbsp-boot-utilities/tree/ba1ea8d0fdb24857553730aa247eb602c7b589ba/uefi_capsule_generation). - The git clone link is: [https://github.com/quic/cbsp-boot-utilities.git](https://github.com/quic/cbsp-boot-utilities.git) and go to cbsp-boot-utilities/uefi\_capsule\_generation/ directory. - OpenSSL certificates: These certificates should be placed in a separate folder named ‘Certificates’. - The `QcFMPRoot.cer` (or `NewRoot.cer`) should be provided in the BOOT DT at `/sw/uefi/uefiplat/QcRootCer`. | Linux | Windows | | --- | --- | |

| ## Steps to generate capsule files 1. Setup the environment. python3 capsule_setup.py Copy to clipboard 2. Generate firmware version file. python3 SYSFW_VERSION_program.py -Gen -FwVer 0.0.A.B -LFwVer 0.0.0.0 -O SYSFW_VERSION.bin Copy to clipboard where A, B are the version numbers. | -Gen | Generates a new firmware version file. | | --- | --- | | -FwVer | Specifies the firmware version. | | -LFwVer | - Specifies the lowest firmware version. -O: Output file
- name. | 3. Create firmware volume (FV). python3 FVCreation.py firmware.fv "-FvType" "SYS_FW" "FvUpdate_UFS.xml" SYSFW_VERSION.bin Images/ Copy to clipboard | firmware.fv | The firmware volume file. | | --- | --- | | -FvType | Type of firmware volume. | | FvUpdate\_UFS.xml | XML file for firmware update. | | SYSFW\_VERSION.bin | The firmware version file generated. | | Images/ | The directory containing the images. | All the /Images folders are available with all required firmware images, from the FvUpdate\_UFS.xml file. 4. Update the JSON parameters. python3 UpdateJsonParameters.py -j config.json -f SYS_FW -b SYSFW_VERSION.bin -pf firmware.fv -p Certificates/QcFMPCert.pem -x Certificates/QcFMPRoot.pub.pem -oc Certificates/QcFMPSub.pub.pem -g Copy to clipboard | -j config.json | The JSON configuration file. | | --- | --- | | -f SYS\_FW | The firmware type. | | -b SYSFW\_VERSION.bin | The firmware version file. | | -pf firmware.fv | The firmware volume file. | | -p Certificates/QcFMPCert.pem | The certificate file. | | -x Certificates/QcFMPRoot.pub.pem | The root public certificate. | | -oc Certificates/QcFMPSub.pub.pem | The subordinate public certificate. | | -g <FMP GUID> | The firmware management protocol (FMP) GUID. | 5. Generate the capsule file. python3 GenerateCapsule.py -e -j config.json -o .cap --capflag PersistAcrossReset -v Copy to clipboard | -e | Enable capsule generation. | | --- | --- | | -j config.json | The JSON configuration file. | | -o kodiak\_fw\_zak2.cap | The output capsule file. | | –capflag PersistAcrossReset | The flag to persist across reset. | | -v | The verbose mode. | Last Published: Dec 30, 2024 [Previous Topic Storage](https://docs.qualcomm.com/bundle/publicresource/80-70017-4/topics/storage-developer-touchpoints.md) [Next Topic Develop](https://docs.qualcomm.com/bundle/publicresource/80-70017-4/topics/develop-boot-public.md)
