6     LLEXT EDK (Extension Development Kit).
11 This sample demonstrates how to use the Zephyr LLEXT EDK (Extension Development
26 providing some level of isolation - although the kernel one still has access
29 Note that the kernel extension is only available when the EDK is built with
33 The application is built using the Zephyr build system. The EDK is built using
34 the Zephyr build system as well, via ``llext-edk`` target. The EDK is then
38 during build time, which is not really practical. This sample is about the EDK
41 Zephyr application - even on different machines, using only the EDK. At the
43 different teams, using the EDK provided by the application developer.
45 Building the EDK
48 To build the EDK, use the ``llext-edk`` target. For example:
50 .. zephyr-app-commands::
51    :zephyr-app: samples/subsys/llext/edk/app
53    :goals: build llext-edk
54    :west-args: -p=always
57 Copy the EDK to some place and extract it:
59 .. code-block:: console
61     mkdir /tmp/edk
62     cp build/zephyr/llext-edk.tar.xz /tmp/edk
63     cd /tmp/edk
64     tar -xf llext-edk.tar.xz
68 .. code-block:: console
70     export LLEXT_EDK_INSTALL_DIR=/tmp/edk/llext-edk
72 This variable is used by the extensions to find the EDK.
80 .. code-block:: console
82     export ZEPHYR_SDK_INSTALL_DIR=</path/to/zephyr-sdk>
87 .. code-block:: console
89     cmake -B build
90     make -C build
95 .. code-block:: console
97     cmake -B build -DLLEXT_EDK_INSTALL_DIR=/tmp/edk/llext-edk
98     make -C build
105 .. zephyr-app-commands::
106    :zephyr-app: samples/subsys/llext/edk/app
109    :west-args: -p=always
114 .. code-block:: console
