I have APM2, XBee Pro 900, connected to MinimOSD without TX line as advised. When I power up the system, the MinimOSD always shows Booting, then "Update Charset" and goes no further. If I press the hard reset it works fine again, but never on initial bootup. It also does this if I unplug the XBee and connect the MinimOSD directly to the APM with all pins connected.
Is anyone else having this problem? This does not seem like normal behavior.
I have also re-updated the firmware and charset with the MinimOSD software and nothing changed.
