5.16.4 Accessing the peripheral
The SBCX Linux kernel is pre-configured with support for the WLAN and
Bluetooth subsystems. The DWM is normally disabled. Please see below
the commands for enabling it.
5.16.4.1 Enable DWM
echo 107 > /sys/class/gpio/export
echo low > /sys/class/gpio/gpio107/direction
echo 199 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio199/direction
echo 1 > /sys/class/gpio/gpio199/value
usleep 150000
echo 0 > /sys/class/gpio/gpio199/value
usleep 1000
echo 1 > /sys/class/gpio/gpio199/value
echo 107 > /sys/class/gpio/export
echo low > /sys/class/gpio/gpio107/direction
sleep 1
echo high > /sys/class/gpio/gpio107/direction
5.16.4.2 Wireless LAN
Wireless LAN can be managed with the standard networking and
wireless tools (
