+--external=<gpio|timer>
+    Perform energy measurements using an external device unknown to dfatool.
+    With --external=gpio: Assume the device has a trigger input connected to timer-pin and toggle it when starting/topping a transition
+    With --external=timer: Assume the device does not have a trigger input. Perform in-band signaling using board LEDs instead.

 --trace-filter=<transition,transition,transition,...>[ <transition,transition,transition,...> ...]
     Only consider traces whose beginning matches one of the provided transition sequences.
     E.g. --trace-filter='init,foo init,bar' will only consider traces with init as first and foo or bar as second transition,
