I still wonder if the GPS subsystem doesn't have a suitable software-activated power-down mode already, i.e., the "Sleep State" and the "Backup State". You wake up from them via a hardware signal (EXTINT or reset, respectively), so it does seem rather low-level. Adding switches to cut power is rather brute-force and it may have unintended consequences, such as current creeping in over other paths, and loss of "expensive" internal state. - Werner _______________________________________________ hardware mailing list hardware@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/hardware
