Improvements:

  • Add configurable battery chemistry
  • Add per-chemistry LPCOMP wake threshold and boot lockout voltage
  • Add configurable enabled/disabled state for boot lockout
  • Reduce Li-ion/Li-Po lockout threshold to 3.0V from 3.3V
  • Initialise FS earlier in the startup process to allow reading configured settings for boot lock

Fixes:

  • Add additional shutdown reason "None" for instances where the reason isn't set
  • Boot lockout disabled by default
