*J53.4 (UART2_nCTS).
==Usage==Software delivered along with [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)#XUELK_software_components|XUELK 1.0.0]] provides all the required stuff - specifically device drivers and user space tools - to enable and use wireless interfaces. The following sections describe this in more detail. During the Linux kernel bootstrap, the following messages are printed out during the detection of the wireless chipset:<pre>wilink-wl-en: 3300 mVwl1271_sdio mmc1:0001:2: legacy platform data not found, trying device treewl12xx_driver wl12xx.0.auto: Direct firmware load failed with error -2wl12xx_driver wl12xx.0.auto: Falling back to user helperwlcore: loaded</pre>===WiFi===Enable of The following example shows how to:*enable WiFi interface, configured as <code>wloan0</code>*scan the environment for available networks
