It is assumed that the development environment has been set up.
 
−
* start the Linux development VM and login into the system
 
−
* open a terminal window and ''cd'' into Linux kernel source code

−
<pre class="workstation-terminal">
 
−
cd sdvx/linux/

−
* in case of needs you can update your local repository with the following git command

<pre class="workstation-terminal">
 
−
git pull

−
* configure the build environment

−
<pre class="workstation-terminal">
 
−
source ~/env-lite.sh

</pre>

−
* to build the binaries run the following commands:
 
−
 
−
<pre class="workstation-terminal">
 
−
make imx_v7_axel_defconfig
 
−
make UIMAGE_LOADADDR=0x10008000 uImage imx6dl-sfczg-cb0043.dtb

</pre>

−
:The former command selects the default SDVx 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/sdvx/</code> with the following commands:
 
−
 
−
<pre class="workstation-terminal">
 
−
cp arch/arm/boot/uImage /tftpboot/sdvx/linux/
 
−
cp arch/arm/boot/dts/*.dtb /tftpboot/sdvx/linux/

</pre>
