=== Locating configuration file ===

The initial CPU configuration is part the following device tree source file:
* arch/arm/boot/dts/imx53.dtsi
<br />
Shared module configuration can be found in the following file:
* arch/arm/boot/dts/imx53-vmx53.dtsi
<br />
The specific module configuration customised for i.MX53 SODIMM PC Module is part of these device tree source files:
* i.MX53 SODIMM PC Module Max: arch/arm/boot/dts/imx53-vmx53-557.dts
* i.MX53 SODIMM PC Module Pro: arch/arm/boot/dts/imx53-vmx53-668.dts
* i.MX53 SODIMM PC Module Basic: arch/arm/boot/dts/imx53-vmx53-779.dts

=== Configuring USB H1 device ===
==== Host mode ====
<syntaxhighlight lang="bash">
&usbh1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usbh1>;
phy_type = "utmi";
disable-over-current;

status = "okay";
};
</syntaxhighlight>

=== Configuring USB OTG device ===
==== Host mode ====
<syntaxhighlight lang="bash">
&usbotg {

status = "okay";
};
</syntaxhighlight>

==== Peripheral mode ====
<syntaxhighlight lang="bash">
