<br>
</span>well, if you just want to adjust the code to replace the Wandboard<br>
definitions with your i.MX 6Q Sabre Lite, it is actually that simple.<br>
You only have to change the settings in above mentioned file with in the<br>
17.02 release.<br>
<br>
If you want to add support of your board beside of the Wandboard<br>
support, you will have to insert a new layer of board definition. But<br>
being in your position I would first change the current Wandboard<br>
settings to see whether it works in general.<br>

<br>
</span>It is the very same file. You have to change the value of RAM0_SIZE.<br>
<br>
