Recorder V2 charging screen lockups
dreamlayers:
I've used the latest daily build (r14396), flashing rockbox.ucl, and the problems still occurred. I've posted it to Flyspray: http://www.rockbox.org/tracker/task/7631

I have had this problem with a jukebox FM recorder in the past and now with a v2 recorder. I am wondering if it has something to do with applying too much voltage to the box and damaging something in the charging circuit. I plugged mine into a charger for about 5 mins and found out later that it was putting out 9 Volts instead of the rated 6 (it was a supplied archos charger but I picked up the recorder of ebay so it was used- I believe the archos charger is a regulated power supply so it should read 6V open). Im not sure if this has anything to do with it but I figured I would add it to the discussion.
This problem is a real pain when your battery is low because you have to wait until the charge is high enough to start by itself in order to play music while it is charging.

I cannot be certain that the V2 Recorder I have is okay hardware-wise. I certainly didn't apply a high voltage, and the previous user charged it via USB, but he got it off eBay without a charger and who knows what the device experienced before then. That's the main reason why I originally posted here instead of making a bug report in Flyspray.
I nevertheless suspect this is a Rockbox issue based on my detailed overall observations. I find it hard to imagine a hardware failure which would cause the behaviours I observed.
I don't know if this thread should be locked because it may be inconvenient to have information in two places (here and in Flyspray).
dreamlayers:
I did some more investigation and found that the lockup or power-off is caused by Rockbox detecting a low battery voltage because IDE power is needed to measure battery voltage and that is off while charging. This means it's definitely a bug and not a hardware problem. For more information see http://www.rockbox.org/tracker/task/7631 . I am locking this thread so the discussion isn't in two places. If you object to the lock, send me a private message.
