Faulty playback on Ipod Nano 4Gb 1st Gen

[LambdaCalculus]

Here's hoping that someone is willing enough to step forward and help out!

I also posted a message to the developer mailing list.  Hopefully I get some nibbles.

I'd just rather have people see clearly that this is a problem, and it needs to get solved, rather than just look away and cover their ears and hope, which is what it feels like they want to do. People are willing to give you output from the debug screen, but as soon as you mention that someone needs to actually work on it, the response is "Well, I'd rather just go back to an old build and let someone else do it."

The worst part of it all is it's easier for the masses to see a bug and say "Oh, well this doesn't look safe!" and turn away, whereas the inquring minds among us see a bug and ask, "Well, let me if I can replicate it and get some information to give to the devs."

If I had a nano that was having this issue, I'd glad donate it in the name of bug fixes. Unfortunately, it's just me, my iPod video, and my Archos JBR v1...

FYI, I'm using 13990 (downgraded from daily couple weeks back), and I'm still having the problem. I think it was the bootloader upgrade that triggered it. Who knows

[Llorean]

The official Rockbox bootloader dates back to long before this problem starts showing up or was reported by anyone...

So which bootloader upgrade are you referring to?

[mikelx215]

The current boot loader isn't causing any trouble for me that I know of.

Maybe you're experiencing a different bug or you're still using a post r13990 build?

Hello,

Just to add my 2 cents. R13990 cures the "problem" for me. And to quickly see (literally) if there's the problem in a given revision, load a video with mpegplayer : it starts Ok but a few seconds later, colored or noisy blocks are randomly visible and sound has the symptoms described earlier in the post.

I'll give the old build a go. For some reason copying across USB on the latest build is insanely slow....revert back to the Apple firmware and all is good so I think it could be more than just playback.

[Chronon]

Are you claiming that the current build causes the Apple firmware to transfer more slowly via USB?  Apple's emergency Disk Mode launched from flash ROM (what Rockbox currently uses for USB transfer) is known to be much slower than the USB connection established through the firmware.  I just want to be clear on what you're saying.

currents build causes "instruction undefined" when playing mp3

Do you even own a Nano?  In other posts you've said you have a 5th Generation iPod.  If so, please provide the other information required by our posting guidelines, like the specific build revision number of the build you are using.

my friend came to me and i installed rockbox on his Nano, will provide full information about build and error later.

Ps. Problem gone with my 80gb ipod , using rockbox and njoying the life

Thank you x 10!   This really saved my vacation - I updated to a post 13990 build before I left on my vacation. Luckily, our second hotel has internet, and I found this thread and this download link.

I also have a 1st gen 4GB iPod Nano (bought pretty early on) and with all post 13990 builds (downloaded after July 30, 2007)  there's terrible skipping and glitching when playing mp3's. As others have pointed out, it seems that higher bitrate tunes are more prone to causing this. After a few minutes your tunes sound like lo fi, low bit-rate rubbish!

For people with an affected iPod Nano, currently there are no working Rockbox builds online (save the 13990 one, which is well hidden in the forums).

Until this is solved, there ought to be a little notice about this on the current build page. Otherwise people with affected iPods will turn away from Rockbox.

Is there anything I can do to help tracking this down? I really want to be able to get the goodies in the newer Rockbox builds...

Well, that depends on what you mean by "online".  It is still quite accessible from svn.
