Yes. The system would be shutdown immediately when the battery is about
3v3. I think we could add some detecting and handling at u-boot to avoid
booting up when system tends less voltage.
A problem here could that if we read -- and clear -- the PMU INT# stuff
in U-Boot (to get LOWBAT) the general coldplug actions driven by
inheriting the INT# bits will be broken in Linux. Well with the
patchset I sent yesterday we take care of it in early Linux boot anyway
and shut down in that condition.
Currently we measure the voltage from battery directly. If using coulomb
counter battery, we should get the reading from battery itself.
Currently battery do not set any parameter yet, so the reading might be
incorrect.
But eventually, we should read the parameter directly from the battery
via HDQ.
Tony Tu
be arrived at from these measurements, and we need to check that
lifetime on a real phone actually left in standby until it flakes out.
It sounds great. I will let HW people to know this suggestion and to
see any possibilities to have this observation.
OK.
