I’m having problems setting ms_v_charge_mode. I do it this way, but it fails at runtime: StdMetrics.ms_v_charge_mode->SetValue( chademo ? "performance" : "standard"); This is the trace I get, so it seems to fail somewhere else: I (6451) events: Signal(vehicle.charge.mGuru Meditation Error of type LoadProhibited occurred on core 0. Exception was unhandled.

Any one got a clue? Regards, Geir
