* in case of needs you can update your local repository with the following git command
<pre class="workstation-terminal">
dvdk@vagrant:~/desk-mx-l/linux$ git pull

<pre class="workstation-terminal">

:The former command selects the default DESK-MX9-L configuration, while the latter builds the kernel binary image with the required u-boot header and the kernel device tree.
Default Linux kernel configuration can be changed by using the standard <code>menuconfig</code>, <code>xconfig</code>, or <code>gconfig</code> make target. Subsequent builds just require <code>uImage</code> make target to update the binary image. Once the build process is complete, the kernel binary image is stored into the <code>arch/arm/boot/uImage</code> file. Both this file and the kernel device tree can be copied to the tftp root directory <code>/tftpboot/desk-mxmx9-l/</code> with the following commands:
<pre class="workstation-terminal">
dvdk@vagrant:~/desk-mx-l/linux$ cp arch/armarm64/boot/uImage Image /tftpboot/{{{kitdesk-repo}}}mx9-l/dvdk@vagrant:~/desk-mx-l/linux$ cp arch/armarm64/boot/dts/freescale/*.dtb /tftpboot/{{{kitdesk-mx9-repo}}}l/
</pre>
Usually, kernel modules are installed with <code>make modules_install</code> command, but this method installs the modules into the <code>/lib/modules</code> directory of you your MVM, which is not what you want.
A better way to deploy kernel modules while cross-compiling is
<pre class="workstation-terminal">
dvdk@vagrant:~/desk-mx-l/linux$ mkdir modules-installdvdk@vagrant:~/desk-mx-l/linux$ make INSTALL_MOD_PATH=modules-install modules_installdvdk@vagrant:~/desk-mx-l/linux$ cd modules-installcd dvdk@vagrant:~/desk-mx-l/linux/modules-install && $ tar cvzf ../modules.tar.gz . && cd ..dvdk@vagrant:~/desk-mx-l/linux$
</pre>
<pre class="workstation-terminal">
