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
