==Peripheral SD==
=== Device tree configuration ===
''N.B.'' The USDHC interface is re-configured on carrier device tree because of the ''Card Detect'' pin (which is related to the real board hardware implementation).
==== AURA SOM ====
Here below an example of device tree configuration used on standard DAVE's kit for the ORCA SOM:
From <code>imx93-aura-cb2001.dts</code>:
<pre>
...
&usdhc2 {
status = "okay";
};
...
</pre>
From <code>imx93-aura.dtsi</code>:
<pre>
...
&usdhc2 {
pinctrl-names = "default", "state_100mhz", "state_200mhz";
pinctrl-0 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
pinctrl-1 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
pinctrl-2 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
cd-gpios = <&gpio3 00 GPIO_ACTIVE_LOW>;
bus-width = <4>;
no-sdio;
no-mmc;
disable-wp;
no-1-8-v;
status = "disabled";
};
...
&iomuxc {
...
pinctrl_usdhc2_gpio: usdhc2gpiogrp {
fsl,pins = <
MX93_PAD_SD2_CD_B__GPIO3_IO00 0x31e

};
pinctrl_usdhc2: usdhc2grp {
fsl,pins = <

};

};

===Accessing the peripheral in AURA SOM===
Once initialized, the SD device is mapped to the standard <code>/dev/mmcblk1pX</code> block device, depending on how many partition are created on the SD card.
====Linux messages at boot time====
If the microSd card is inserted at boot time, the kernel - once the USDHC interface has been initialized - prints the device information and the partition detected like ''p1'', ''p2'', etc.:

=== Additional information ===
If are executed the boot with NFS the file system configuration does automatically mount the uSD partitions.
