History[edit | edit source]
| Version | Date | XUELK version | Notes |
|---|---|---|---|
| 1.0.0 | 1.0.0 | August 2016 | First public release |
Introduction[edit | edit source]
SBC Lynx can be populated with DWM WiFi/Bluetooth combo plugin to easily add wireless connectivity.
This application note describes how to enable these interfaces when working with XUELK 1.0.0
Limitations[edit | edit source]
DWM wireless module shares some signals with mezzanine board connector J53. Thus, when DWM module is used, the following signals must be left floating:
- J53.1 (UART2_RX_DATA)
- J53.2 (UART2_nRTS)
- J53.3 (UART2_TX_DATA)
- J53.4 (UART2_nCTS).
Usage[edit | edit source]
Software delivered along with 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:
wilink-wl-en: 3300 mV wl1271_sdio mmc1:0001:2: legacy platform data not found, trying device tree wl12xx_driver wl12xx.0.auto: Direct firmware load failed with error -2 wl12xx_driver wl12xx.0.auto: Falling back to user helper wlcore: loaded
WiFi[edit | edit source]
The following example shows how to:
- enable WiFi interface, configured as
wloan0 - scan the environment for available networks
