Hmm, I've never heard of GPIO problems when going into CPU suspend. There have been a severe issue in GTA01 with current still going into the CPU when powering down (PMU Standby) and causing the CPU to emit transients. The problems was that such transients could cause the modem's reset line to be asserted, via that transistor. This in turn brought the modem out of "power off", and it happily started to burn power, even though the system was supposedly off. We've never seen that problem with GTA02. That may be because GTA02 has that modem "power switch" (U1705). I think it can't hurt to route the modem's reset signal to a PMU GPIO, to make sure it's stable even if we cut power to the CPU. - Werner _______________________________________________ gta02-core mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/gta02-core
