Para que el kernel compile las .dts en dtb se ha de añadir en el Makefile de arch/arm/boot/dts/

<div class="line number4 index3 alt1"><code class="java spaces"> </code><code class="java plain">imx6q-igep-base0040rc2.dtb \</code></div>
<div class="line number5 index4 alt2"><code class="java spaces"> </code><code class="java plain">imx6q-igep-base0040rd102.dtb \</code></div>

| class="code"|<div class="container" title="Hint: double-click to select code"><div class="line number1 index0 alt2"><code class="java plain">make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- imx6_igep0046_defconfi</code>
</div>
</div>
|}</div>
</div>
</div>
3- Ejecutar el menuconfig para optimizar la configuracion a traves del menú.
<div class="code panel pdl conf-macro output-block" data-hasbody="true" data-macro-name="code"><div class="codeContent panelContent pdl"><div id="highlighter_965738" class="syntaxhighlighter sh-confluence nogutter java">

4- Compilar la imagen los modulos y las dtb
<div class="code panel pdl conf-macro output-block" data-hasbody="true" data-macro-name="code"><div class="codeContent panelContent pdl"><div id="highlighter_56426" class="syntaxhighlighter sh-confluence nogutter java">

5- Instalar en el rootfs los modulos del kernel que son cargables ( es decir que no estan built-in)
