Risks relating to iPod charging from wall socket.

[kamalneet]

yes with me away from my ipod charging and on rockbox (rebooting again and again) it destroyed  two chips by philips

1. philips T1211 DC/DC converter ( http://www.rockbox.org/twiki/bin/view/Main/IaudioX5HardwareComponents#Philips_TEA1211_DC_DC_Converter )

2.philips PCF50605HN (PMU) power management unit ( http://www.chipworks.com/WebReports/ShowOverview.asp?ReportID=2368 )

i had put off charging after 2 hours and now have to open all of my ipod and operate it while opened only due to over heating of these two chips

since these are intergerated on the board and cannot be replaced
i am stuck up

not to mention that i cannot use rockbox any more due to over heating of these chips ,i can use apple firmware but that too does not give me back up any more

now DONT trust rockbox over charging issue till this date

Please change your topic name. You changed your iPod firmware to enter deep sleep early, and this is what caused your problem.

We've also told people that to charge properly in Rockbox using the iPod charger, rather than USB, you hold the Menu button down while plugging it in, in Rockbox. You did not do this.

The problems you encountered were the result of your actions, especially the fact that you modified the settings of your Retail Firmware outside the bounds that are officially changeable.

woah thats scary!

so if i plug my ipod in without holding down menu i could fry my ipod?

also if i am running the apple OS and i plug my ipod into the wall charger then it reboots into rockbox. can i stop this happening? also if this happens and i leave the ipod to charge overnight (i always did this before i had rockbox) then will this fry my ipod?

[Llorean]

The iPod will not reboot into Rockbox until it enters Deep Sleep. I believe this is after 48 hours of Sleeping, though I'm not 100% certain. At that point, it shuts off, then turns back on because the power cable is in.

At this point it goes into an endless reboot loop.

The problem is that the emergency disk mode reboots your iPod if there's no USB connection (which there isn't with the charger) but Rockbox goes into disk mode when it detects a USB cable providing power independent of connection (which the charger does).

You'd have to leave your iPod plugged into the wall for a couple days for this situation to turn up normally. It also can't happen at all if you charge from your computer, or firewire. Only USB charging in Apple's firmware, when Apple's firmware goes into Deep Sleep and then their disk mode continually tries to boot Rockbox.

there should be a warning about that somewhere in the manual
Do not leave your rockboxed ipod charging for more than 48 hours at a time.

My question is why someone would leave their ipod plugged in for that long anyway? 

But if you hold menu, as I've done to charge the ipod sans computer, you'll be totally fine..

[evilbert222]

My question is why someone would leave their ipod plugged in for that long anyway? 

you might have an old ipod with a dead battery that you keep plugged in for your home stereo etc..

[SilleeString]

True but in that case you'd be aware if it were rebooting non-stop.  To keep plugged in in that case while not in use just doesn't make sense to me

[Llorean]

The other thing is, if you have it plugged into a home stereo, either A) you're in Rockbox (in which case this doesn't happen) or B) You only ever use retail (which means why do you have Rockbox installed?)

While this thread is a valid concern, it came about through the user's carelessness and the fact that he'd modified his retail firmware to sleep very early.

By the time Rockbox is actually released, I'm fairly certain either it will have its own USB mode, or it will be able to tell the difference between a power charger and an actual USB connection, and reboot or charge depending on which it is.

well i cant tell you what  happened i was asleep when i woke up i didnt know what was in it , its only in the late after noon when i put it on its dc/dc chip became hot while playing songs with rock box , it could also be that i had just updated .rockbox folder the previous day so , i dont know real cause , but dc/dc chip was spoilt due to continuous rebooting plus there is no option to default boot apple f/w which would have saved it , why cant be multiple option menu given through rockbox developers ,



i am sorry that i just fiddled with my little ipod (my baby) i shouldn't have put rockbox in first place (my mistake) , everything was going fine

[Llorean]

It's been explained many times why the Rockbox bootloader doesn't have a menu. Its purpose is to boot Rockbox as quickly as possible. The iPodLinux Loader 2 exists for those who need an option.

[kamalneet]

NOTE THAT :and apple firmware  while playing mp3 is not heating up dc/dc chip now means alot is wrong with rockbox power handling



ALSO nobody can wake up in the MIDDLE of the night to HOLD that MENU button (make sense with this) , concerns me for others to come

[Llorean]

The processor runs at a faster speed in Rockbox, which is most likely where the heat is coming from.

Also, you plug it in with the menu button held down. Also, it's not Rockbox's fault that your iPod was set to enter deep sleep MUCH earlier than a normal one. If it hadn't been, the problem wouldn't have happened to you, as you would've awakened and unplugged it far earlier than the problem happened.

[kamalneet]

you are not trying to understand the point here ,forget the past what has happened to my ipod ,
i am trying to make a point here to rockbox developers that why not they make charger pluggin in easier  ,and that is no MENU button pressing ,just a simple plug in  so that rockbox never reboots
,no reboot means no chaos .

who knows someday someone else will make the same mistake too.

it is another improvement which rockbox should achive that is what i am trying to say

[Llorean]

And I said earlier in this thread that at some point I'm sure they WILL make it detect whether you've plugged in a charger or a USB cable, but that's not possible right now.

It's six posts earlier, the one I started with "The other thing is". You'll see it in there, at the end.
