I'm using HS EMV with am437x CPU with SDK: am437x-hs-evm-linux-sdk-bin-06.03.00.106
to test suspend to ram but even despite fact I set that console should was it's not the case. Console just freeze and only option is to reboot board.
Log looks like:
root@am437x-hs-evm:~# echo mem > /sys/power/state
[ 140.705722] PM: suspend entry (s2idle)
[ 140.709523] PM: Syncing filesystems ... done.
[ 140.730689] Freezing user space processes ... (elapsed 0.001 seconds) done.
[ 140.739728] OOM killer disabled.
[ 140.743125] Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
Any hints? Thanks.
