RTC
To set the RTC first set the date from Linux shell, type:
$ date 2013.08.27-15:43
Then set the real time clock from Linux shell, type:
$ hwclock --systohc
Power down your board wait 15 seconds and power up. Check your system with date and the time should be up to date.
Audio record/play
$ aplay /usr/share/sounds/alsa/Front_Center.wav $ arecord -f cd -d 10 -D hw:0,0 test.wav $ aplay test.wav
WLAN
List SSIDs, from Linux shell type:
$ ifconfig wlan0 up $ iw wlan0 scan
Connecting to an encrypted network
Find your network from the above scan command.
$ wpa_passphrase <YourAP> <YourPassword> >wpa.conf $ ps | grep wpa_supplicant *kill the wpa_supplicant process if exist. $ wpa_supplicant -Dnl80211 -iwlan0 -c./wpa.conf -B $ udhcpc -iwlan0 $ ifconfig
