    256256  - Note that some out-of-tree kernel modules do not follow the suggested Makefile standards and may need to be modified to use the CROSS_COMPILE prefix and/or specify the kernel directory (as opposed to the above example where you do a make in the linux dir and set M to the path of your module)

     259== Building External or Out-of-Tree Kernel Modules
     260
     261Gateworks Venice BSP now creates images that have built in support for building external or out-of-tree kernel modules on a target board, allowing users to extend the functionality of the kernel with custom or third-party modules. Below are some examples demonstrating how to build and install external modules on a one of our Venice boards:
     262
     263Before building any external kernel modules, it's essential to ensure your system has necessary dependencies installed. We recommend starting with an update of package lists followed by the installation of essential tools. Run the following commands:
     264{{{#!bash
     265apt update
     266apt install -y build-essential git bc file
     267}}}
     268
     269{{{#!bash
     270cryptodev-linux:
     271                        git clone http://github.com/cryptodev-linux/cryptodev-linux
     272                        cd cryptodev-linux
     273                        make && make modules_install
     274                        modprobe cryptodev
     275
     276nrc7292 (mac80211):
     277                        git clone http://github.com/Gateworks/nrc7292
     278                        cd nrc7292/package/src/nrc/
     279                        make && make modules_install
     280                        modprobe nrc
     281}}}
     282
     283These examples illustrate the process of building and installing external kernel modules. Users can adapt these instructions for other modules as needed, ensuring that dependencies are met and the module is properly installed and loaded into the kernel.
     284
     285It's important to note that while many out-of-tree kernel modules follow standard Makefile conventions and can be built and installed using a simple 'make && make modules_install' command sequence, some modules may not adhere to these conventions.
     286
     287These non-standard modules may require modifications to their Makefiles or build processes to ensure compatibility with the standard build procedure. In such cases, it's advisable to consult the module's documentation or source repository for specific instructions on building and installing the module.
     288
     289Always verify the requirements and instructions provided by the module's developers to ensure successful integration with your kernel environment.
