Suspend mode doesn't work

[poly123]

Hi,

any ideas what to change to make use of the suspend mode?
I used "echo mem > /sys/power/state" for achieving this on BBB with TI SDK8. (http://processors.wiki.ti.com/index.php/AM335x_Linux_Power_Management_User_Guide)

With AM3352 SoM and latest Debian image from Olimex this does not work.
I get "bash: echo: write error: No such device" when trying this.

Any ideas?

As /sys/power/state does not exist, it's one of: you've not config'ed kernel for it, not loaded module(s) or the special file has changed name.  Go hunting

Thanks for your reply.

The file /sys/power/state does exist.
"cat /sys/power/state" gives always "Freeze" which doesn't make that much sense.

I will have a look into it over the next days and if I find a solution I will post it here.
