Under Debug -> view battery I see Battery 3.6 V (elsewhere this is interpreted as 8% charge), Charger: present, State: Discharging. My read through the code seems to indicate that the charger should be enabled under these conditions. Am I missing something or is this a bug? A little more background/information: This e250 will not charge in the original firmware either." Then there is a possible hardware issue. My e260v1 works fine in both retailos and rockbox. I've been really busy and out of the loop, so maybe code was changed? Though that would only explain a change with rockbox, not OF. "Does anyone know why this would not trigger a call to enable_charger() making the charge_state go to CHARGING?" Perhaps it does and then the charger finds the current flow is too low and triggers a false 'done'? The SVN code (as I saw it last) will attempt to start a charge cycle at 3.6V for sure. It should do a topoff at 4.16V or below. The c200 will always top off when plugged but that isn't really the best way to do things. On that model, only the 'flakey' measurement is available for qualifying the battery state.
