Hi,
I am using BeagleBone Black (+Debian) and have successfully installed DS1307 Real Time Clock.
In a C program I need to set system sleep and wakeup for certain time periods.
I have tried:
sudo rtcwake -m mem -s 20 -d rtc1
-->
rtcwake: open failed: /sys/class/rtc/rtc1/device/power/wakeup: No such file or directory
rtcwake: /dev/rtc1 not enabled for wakeup events
How do I "enable rtc1 for wakeup events"?

I'm not familiar with rtcwake, but searching around it sounds like there might not be support for it in the Beaglebone Black's 3.8 kernel yet: https://groups.google.com/forum/#!topic ... UxM5pGMWLY
Try posting the question in the Beaglebone Black forum to see if folks there can give a better answer on support for rtcwake too.
