Hello!
We're using an BeagleBoard xM, and I'm trying to get low power OFF mode. I cofigured PRM_VOLTCTRL register for toggling SYS_OFFMODE when all power domains in off mode (PRM_VOLTCTRL = 0xC) , but in this case system* immediately resumes after suspend*. Same results i have when PRM_VOLTCTRL = 0x4. But i don't see wake-up sources. According register snapshot all power domains put to OFF mode. POWERDOMAIN PREV STATES: PM_PREPWSTST_MPU: 0x00000000 PM_PREPWSTST_CORE: 0x00000000 PM_PREPWSTST_SGX: 0x00000000 PM_PREPWSTST_DSS: 0x00000000 PM_PREPWSTST_CAM: 0x00000000 PM_PREPWSTST_PER: 0x00000000 PM_PREPWSTST_NEON: 0x00000000 PM_PREPWSTST_IVA2: 0x00000000 PM_PREPWSTST_USBHOST: 0x00000000 *Can anybody say something about this problem?* Also BeagleBoard xM correctly enters to suspend mode and correctly wakes-up from keyboard when SYS_OFFMODE signal is disabled (PRM_VOLTCTRL = 0x0). In attachment REGISTER_SNAPSHOT contains full CM & PRM register dump after resuming. *4478.REGISTER SNAPSHOT.docx*<http://e2e.ti.com/cfs-file.ashx/__key/communityserver-discussions-components-files/447/4478.REGISTER-SNAPSHOT.docx> Thanks, Andrew. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
