tvg:
May be this could investigate the situation.

Sorry if I'm not in topic.
danhibiki:
I have the most updated Apple OS that I know of, version 1.3.1
Llorean:
So far, everyone experiencing problems has been using 1.3 or 1.3.1, while I'm using 1.2. It's *possible* this is the cause, but I really need to find someone with 1.2 who has access to a Windows machine to upgrade and test.
If all else fails, I'll have access in a week or two and will sacrifice mine to the upgrade.
bascule:
I could do that. I have a Rockboxed nano on an older Apple firmware version (can't verify which ATM, because I'm just charging it.
I'd happily have a go. I can also compile earlier builds and test them out if required prior to doing the Apple upgrade. I presume you can't then downgrade the Apple firmware?
Llorean:
It should be possible to downgrade the apple firmware, but downgrading the flash is questionable. As in, it should be doable, but it may not be as easy. The on-disk firmware can just be overwritten with an older apple_os.ipod generated by iPodPatcher, but it *may* not be willing to flash an older flash image (we'd have to write it to the device, and set the flag that says it needs to be written, and of course we need a means to verify the image is good first as we wouldn't want it flashing a bad image).
If you're using a version pre 1.3, what I'd like to ask is that you upgrade to the current build of Rockbox, play around a while, make sure playback seems normal. Then in the Debug menu, dump the ROM contents, and back that file up somewhere. Then upgrade your Apple firmware. It *should* do the flash update (ask that you plug in, and show a progress bar). After that, reinstall the Rockbox bootloader, and see if you're now unable to play any music (the sorts of errors reported in this thread.) Be aware, if this *is* the cause it may be some time before there's a fix (depending on what aspect is the cause.) If your iPod *is* now experiencing the crashes, dump the ROM contents again. Hopefully I can talk someone who knows what they're doing into comparing the two files to see if they handle hardware initialization differently.
If you have any doubts, feel free to back out, as I said, if nobody else gets around to it, I'll sacrifice mine once I get back (assuming my laptop is repaired by then), and if you have any questions, ask them before you start so we can make sure everything gets done. ;)
Edit 1: Compiling two builds I ask those of you having problems to try. Amiconn has some theories as to what might be the problems, these will hopefully illuminate it.
Edit 2: Please try both of these builds and let me know if either (or both) works.
