Greetings Mythizens, I'm still having trouble test setting the alarm<br>
wakeup. I enter the test script into the terminal as per the wiki:<br>
<br>
daryl@daryl-A780L3C:~$ cat /sys/class/rtc/rtc0/wakealarm<br>
daryl@daryl-A780L3C:~$ SECS=`date -u --date "2013-09-02 15:45:00" +%s`<br>
daryl@daryl-A780L3C:~$ sudo sh -c 'echo 0 > /sys/class/rtc/rtc0/wakealarm'<br>
<br>
And when I ask for a report of the alarm state, IRQ is always "= no" :<br>

Hopefully it's just a typo in your email, but there's a step missing:<br>
<br>
sudo sh -c 'echo $SECS > /sys/class/rtc/rtc0/wakealarm'<span class=""><font color="#888888"><br>
<br>
-- <br>

That line was in there, something else I'm noticing is that the " /sys/class/rtc/rtc0/wakealarm" file is blank, I opened it via the GUI file system. Is that normal and/or functional? Shouldn't I be able to see a script?</div>
