I’ve got a Boron running on the 1.4.2 firmware and I’m having some weird charing issues. Intermittently it will say “discharging” and stop charging the device, and then run the battery down to 0. If I unplug the battery and the device from power, then power it back up, then plug the battery in, it will operate normally for awhile, but the problem seems to recur. I’ve seen this happen on two devices running 1.4.2. Sometimes it will say not_charging, other times it will say discharging. If there’s no battery attached it never has a problem. Here’s a screenshot of the history I downloaded:
I’m using a 5V / 2 Amp power supply wired directly to the VUSB pins, so there’s plenty of current available. I’m going to triple check the input voltages etc, but curious to know what’s going on as I’m about to begin deploying these in a larger-scale pilot project.
