Source Tree Structure
|
|
#####################
|
|
|
|
Understanding the Zephyr source tree can be helpful in locating the code
|
|
associated with a particular Zephyr feature.
|
|
|
|
The Zephyr source tree provides the following top-level directories,
|
|
each of which may have one or more additional levels of subdirectories
|
|
which are not described here.
|
|
|
|
:file:`arch`
|
|
Architecture-specific kernel and system-on-chip (SoC) code.
|
|
Each supported architecture (for example, x86 and ARM)
|
|
has its own subdirectory,
|
|
which contains additional subdirectories for the following areas:
|
|
|
|
* architecture-specific kernel source files
|
|
* architecture-specific kernel include files for private APIs
|
|
* SoC-specific code
|
|
|
|
:file:`boards`
|
|
Board related code and configuration files.
|
|
|
|
:file:`doc`
|
|
Zephyr documentation source files and tools.
|
|
|
|
:file:`drivers`
|
|
Device driver code.
|
|
|
|
:file:`ext`
|
|
Externally created code that has been integrated into Zephyr
|
|
from other sources, such as hardware interface code supplied by
|
|
manufacturers and cryptographic library code.
|
|
|
|
:file:`fs`
|
|
File system code.
|
|
|
|
:file:`include`
|
|
Include files for all public APIs, except those defined under :file:`lib`.
|
|
|
|
:file:`kernel`
|
|
Architecture-independent kernel code.
|
|
|
|
:file:`lib`
|
|
Library code, including the minimal standard C library.
|
|
|
|
:file:`misc`
|
|
Miscellaneous code that doesn't belong to any of the other top-level
|
|
directories.
|
|
|
|
:file:`net`
|
|
Networking code, including the Bluetooth stack and networking stacks.
|
|
|
|
:file:`samples`
|
|
Sample applications that demonstrate the use of Zephyr features.
|
|
|
|
:file:`scripts`
|
|
Various programs and other files used to build and test Zephyr
|
|
applications.
|
|
|
|
:file:`tests`
|
|
Test code and benchmarks for Zephyr features.
|
|
|
|
:file:`usb`
|
|
USB device stack code.
