This guide describes the methods to configure, download, compile, and flash
Qualcomm^®^ Linux^®^ and the associated firmware on supported
devices. **This information is also available in [Simplified Chinese](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-254Y)**.
Qualcomm recommends that you read the [Qualcomm Linux Yocto Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-27) before starting
your build.
### Unregistered users
Unregistered users can sync and build Qualcomm Linux using the [GitHub workflow for unregistered
users](https://docs.qualcomm.com/doc/80-70014-254/topic/github_workflow_unregistered_users.html).
### Registered users
Registered users can use any one of the following three methods to sync and build
Qualcomm Linux. These methods use the Qualcomm Yocto layers and the supporting base
Yocto layers.
| Launcher | CLI | GitHub |
| :---: | :---: | :---: |
| Easy-to-use, GUI-based, Qualcomm Software Center (QSC) Launcher. | Simple QSC command-line interface (CLI). | Instructions to use GitHub based workflow. |
| [Build with QSC Launcher](https://docs.qualcomm.com/doc/80-70014-254/topic/build_from_source_qsc_gui_intro.html) | [Build with QSC CLI](https://docs.qualcomm.com/doc/80-70014-254/topic/build_from_source_QSC_CLI.html) | [GitHub workflow for registered users](https://docs.qualcomm.com/doc/80-70014-254/topic/build_from_source_github_intro.html) |
Note:
Prebuilt binaries along with Platform eSDK links are hosted in the [Release
Notes](https://docs.qualcomm.com/bundle/publicresource/topics/RNO-240626095531/ReleaseNote.html#prebuilt-flashable-images-along-with-esdk).
The Platform eSDK is an installer generated from the Qualcomm Linux image. It
provides a complete Yocto environment that allows you to synchronize, modify,
compile, and install applications and open-source plugins. For more details, see
[How to download the Platform eSDK?](https://docs.qualcomm.com/doc/80-70014-254/topic/how_to.html#howto_build__section_imr_xc4_1cc_vinayjk_07-12-24-1513-38-780).
Note: Qualcomm Linux allows you to
build images for QCS6490 and QCS5430.
QCM6490 and QCS6490 are used
interchangeably in this guide.
