Peripheral WiFi[edit | edit source]

Device tree configuration[edit | edit source]

Here below an example of device tree configuration used on standard DAVE's kit for the AXEL Lite SOM:

From imx6qdl-axelcommon.dtsi:

    pinctrl_usdhc2_sbc: usdhc2-sbc-grp-1 {
	fsl,pins = <
		MX6QDL_PAD_SD2_CMD__SD2_CMD    0x16058
		MX6QDL_PAD_SD2_CLK__SD2_CLK    0x16058
		MX6QDL_PAD_SD2_DAT0__SD2_DATA0 0x16058
		MX6QDL_PAD_SD2_DAT1__SD2_DATA1 0x16058
			MX6QDL_PAD_SD2_DAT2__SD2_DATA2 0x16058
			MX6QDL_PAD_SD2_DAT3__SD2_DATA3 0x16058
	>;
    };

Accessing the peripheral[edit | edit source]

Once initialized, the WiFi device is mapped to the standard wlan0 network device

 === Additional information ===
-Each CAN port appears like a networking interface in the form <code>canX</code> where <b><i>X</i></b> is the port number.
-Information about programming the CAN socket interface is given in the kernel tree under ''Documentation/networking/can.txt''
