"rtcwake: /dev/rtc not enabled for wakeup events"

I forgot to say, that I am using omapl138 SoM (Rev 4) from zoom logic, Angstrom rootFS.

Don't know how to fix this

Best Regards

Hi,

Refer to this link for suspending to RAM, http://processors.wiki.ti.com/index.php/OMAP-L1_Linux_Drivers_Usage#Suspend-to-RAM

Thank you for your answer.

I am afraid that this doesn't help.

Still having same problems.
