iPod 5,5 (80Gb) doesn´t switch on anymore

[daniel54]

Did you charge from within Rockbox? How long between when you charged the iPod and when you next tried to use it?

Charged it for about 10-15 mins and booted it into the emergency disk mode and reset the ipod in itunes to the factory setting and then booted to the apple firmware and then charged the rest of the way.

ps, its a shame its an apple boot loader error, rockbox it really good, would be a shame to have to wave bye to it.

Just to be clear,  when you last shut it down (before the problem) were you in Rockbox or the Apple firmware?

I was in RockBox.  
Edit: Is a RockBox boot loader too far in the distance?

[GodEater]

I assume by Rockbox bootloader, you mean one which resides in the iPod's flash.

To be honest, I can't think of a good reason to do this - the Apple one is usually so reliable, and contains all the emergency routines for things like disk mode and self diagnostics.

We would need a fuller understanding of the ipod hardware (to perform all the initialisations we currently rely on the Apple bootloader to do), plus a working USB disk mode, but running Rockbox from flash (we wouldn't just limit it to a bootloader) would give very fast boot-up times, and also allow features such as hibernation of dircache (as implemented on the iriver H100 series when running from flash).

Our own code in flash would also hopefully not share the same extremely slow emergency disk mode that Apple's firmware has on some models, although that wouldn't be needed as often as Rockbox would by that time have its own disk mode.

Another advantage that some people seem to care about is that the ipod would then be running 100% free software - no Apple code left.

I'm sure there are other advantages, but I think we're getting off-topic.

It should also resolve the extremely annoying "Low Battery" bug if it ever happens.

[DefineByte]

Here's something I forgot to mention that happens when the iPod fails to start. On hitting reset, when Rockbox boots back up I've noticed that the statusbar is not showing up. The statusbar setting is set to off. This is despite the theme I'm using turning it on as well as having manually set it beforehand.

What could cause something like that? Every other setting remains unchanged as far as I can see.

[LambdaCalculus]

I think that bug that was causing settings to not be saved was just squashed earlier.

[DefineByte]

The setting was saved though. It remembers it fine, over multiple starts/reboots. It's only when I get the 'fail to switch on' thing that it forgets it (and seemingly only that one setting).

Doesn't sound like the same thing does it?

I have the same problem with this model of iPod as the starter of this thread.  Seems like it may be in some hang state that runs the battery flat.  This could very well be an issue with the iPod firmware, and it would seem that Apple has some sort of work around because I didn't have any issues prior to installing rockbox.  Of course, without access to their code, reverse engineering the work around may be tough?  I'm trying the recharge from a wall adapter for 48 hrs to see if I can get the (menu + select) to function.

[prokaryote]

If it won't recharge, you may have to disconnect the battery and reconnect the battery?  Here's a link to a "how-to" including a place to buy another battery.

Worst case may have to replace the logic board, see trouble shooting guide.

Question:
Does Rockbox write to flash other than in the installation process?  I'm just throwing ideas out there.  If it does, then in certain cases (i.e. a hang fire issue) it may corrupt some of the memory and this would require a re-flash to correct.  Recharging may not be possible until the firmware is corrected.  Just an idea, any comments?

[prokaryote]

   Success!

Disconnect the battery for a few minutes and reconnect and the system will boot up!  Whew! I thought I'd have to buy a new iPod, the wife would have skinned me alive.

So, it's not a corrupted memory issue, but some sort of hang state that prevents recharging, recognition as an USB device and disables the touch wheel until the battery is totally dead.  This can take some time before this occurs, until then the iPod will not recharge.

[Chronon]

This sounds quite similar to the behavior I saw when I first installed RB on my Gigabeat.  The system was hanging at shutdown and no button presses could be detected.  Since the unit had not shut down it would continue to drain the battery even though it appeared off.  Switching the battery off and then on (disconnecting and reconnecting it) would allow it to be started again.

[mamboman]

wow... sounds pretty nasty.. hopefully it does not happen to me. it's a pain to get the ipod repaired even if under warranty

[MIYU]

i think i might have the same problem as killo777, but i'll try to charge my ipod with the a wall charger for 48 hors to see if it will startup.

prior to this i have charge for several days already on and off( mean connecting and disconnecting trying with different cables). when i tried to reset menu+ select (holding it for over 2 mins) i can hear that my ipod is trying to reset or may have reset but fail  to start up every time, for many times. While the ipod is charging (with the wall charger) i can hear that the disc is spinning. Making a small running sound but nothing startup. No icon, no battery charging icon, no light, Just a black screen.
