80GB Ipod Video won't shut down.

[Logjammer]

I installed rockbox 3.0 on my 80GB Ipod Video recently and it's been having the same problem the previous version did.  I hold the play button to shut down the Ipod and it doesn't shut down, it just reboots back into Rockbox.  Also, another problem I've recently been having is that the battery won't charge when the USB is plugged in (despite the fact that I have selected "yes" to that option.)

Any patches i can load that can fix all this?  I don't want my battery to get drained.

Is the player connected to a charger?

[Logjammer]

Is the player connected to a charger?

no, it does that even when it's not connected to anything.

but yeah even when it's connected to a charger it won't read the battery or something.

[bluebrother]

Sounds like your player is wrongly detecting a charger. Can you check in the Apple firmware if it detects a charger even if none is detected? The hardware can't shut down while a charger is connected, so if it wrongly detects one this behaviour will occur. Plus, in that case it's a hardware issue.

This is probably the same problem that my iPod has:

The USB power section of the LTC4066 IC on the motherboard is defective.  Instead of accepting power, it outputs power back into the USB +5V input.  Because of this, some voltage is present there, and the iPod thinks USB is connected.  (This voltage can actually be measured at the end of the USB cable.)  This causes the iPod to turn on as soon as it is turned off.  This has nothing to do with Rockbox.

Your iPod can probably still charge via FireWire.  There are cables with both USB and FireWire which can be used to charge via FireWire while accessing the iPod via USB.

As for the inability to turn off, you have several alternatives:
- Use the original firmware.  Its off is sleep, and sleep is still possible.
- Cut the trace leading to the IN pin of the LTC4066.  This is what I did.
- Replace the LTC4066.  I thought this was too hard because there is a large solder tab under the chip for heat sinking and there are very tiny parts very close to the chip.
- Replace the motherboard
- Short the USB +5V input to ground when not using USB, eg. via a modified dock connector.  It should be easy, but would waste power.  I didn't try this.

yeah that's what i do to turn off.  i always have to boot into the apple firmware and then hold the play button.

where would such cables be located that will allow my ipod to charge via firewire?

I'm glad I cut that trace.  I just wrote a bit about it on my blog.  The key part is the image showing the defective IC and what to cut.

They're for older iPods but they're still available, for example via Amazon search or overpriced at Best Buy.

I have an idea for a purely software workaround which allows Rockbox to shut down the iPod.  In firmware/drivers/pcf50605.c, pcf50605_standby_mode() sets conditions which turn on the iPod.  Removing the condition relating to USB charging, probably CHGWAK,  would allow the iPod to stay off, though FireWire charging might not turn it on either.  But be careful, because according to the comment, it might be possible to turn off the iPod in a way that requires disconnecting the battery or waiting for it to self-discharge (a month or more I guess).

[Logjammer]

Ok so what's the best way to open up the ipod and what should I use to cut the trace?

[dreamlayers]

There are special tools for opening iPods (eg. eBay search).  I used a piece of plastic I filed down.

For cutting the trace I used a utility knife.  Instead of using force and trying to cut in one pass, I carefully made multiple passes until the trace was cut.

I was searching the forum, and found this to be the exact problem my iPod is having. It's actually a 2G Classic; I bought it on eBay, just because I wanted to have a little piece of history. When I hold the Play/Pause to shut down, it boots back up, just like Logjammer's. If I wanted to try the "software workaround," where do I put that pcf50605.c file? Do I create firmware/drivers in the .rockbox folder?

For a second generation iPods (ones with a firewire connector) the only way to shutdown from Rockbox is to press play/pause until "Shutting down" appears on the display, then flip the hold switch on. The unit will then boot into the Apple firmware, and then it can be shutdown.

[Mikgerdan1991]

Thanks for the quick response. 

Oh, really? That's the shortest way of shutting it down? That's what I have been doing, I just can't see waiting for it to shut down and boot into the Apple firmware to make it sleep every time I want to turn off my iPod. Then after doing that, rebooting it again so that it goes back into Rockbox. Is there no shortcut? If not, that'd be alright. Rockbox is worth it. (Great stuff by the way.  ) But, is there something I can edit in the firmware that will stop it from starting up again, like the guy with the 80GB iPod?

[yapper]

The older iPods don't actually shutdown even under the Apple OF, they just go into a very lower power state ("sleeping"). Rockbox doesn't know how to set the hardware into this state, so the only way is to use the Apple firmware.

The newer iPods can be shutdown by Rockbox, unless the iPod is connected to a charger or has a hardware fault (as described earlier in this thread)

[Mikgerdan1991]

Oh, I see, good point. Is there any chance that Rockbox, um, people, will come back to trying to figure that out, or am I going to have to do what you said before to turn it off?

If so, I have a separate, but related question; I'm converting all my music to WMA. (It just seems, at least to me, the best sounding at 64kbps, which is what I need the bit rate at to have all my music on the iPod.) Would the WMA's play in the original Apple firmware, or would I have to be in Rockbox? I would assume not, but I just wanted to make sure.

[Chronon]

No.  Apple's firmware does not play WMA.
