Hi all, I'm having some troubles putting my OMAP3503(the one without the DSP or SGX modules) board to sleep. I'm using the current master on the l-o git repository. This is the output from dmesg and the count file after suspending twice. The first time it wakes immediately after going down, and the second time stays asleep but says that the core domain didn't enter OFF mode. In either case, the SYS_OFF_MODE signal never asserts. I added some debug code into map_sram_idle() to capture CM_CORE_IDLEST1 and 3 right before it jumps to the final sleep code in SRAM. root@spark:~$ echo mem > /sys/power/state [ Â530.299621] PM: Syncing filesystems ... done.
