80GB Ipod Video won't shut down.

(1/3) > >>

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?

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.
