Phone boot with PWON: weed out short button presses Every standard end user phone has a design provision, most naturally implemented in firmware, whereby the PWON button effects a boot only if it is held down long enough - short presses of this PWON button are detected, assumed to be spurious and cause the fw to power back off instead of proceeding with boot. The present change introduces this standard function in FreeCalypso.
