Ipod Nano 2 plays 8 secs , lots of noise then quit playing becomes inoperative.

<< < (2/2)

DutchRaider:
Thanks for the Hints and Suggestions.
Actions taken : installed Rockbox 3.8.1 this was marked as stable.

2 music pieces installed in separate folder Music2 under the root.
A .wav file of about 20 seconds
A .mp3 file of about 20 seconds

First MP3 when its playing normally about 8 seconds in , noise , song cuts out and Rockbox software hangs.  No buttons are recognized, display stays up  (as before)
Hard Reset needed to clear.
Then further , when I pause it 2 seconds in , and play after at least 10 secs, that the file became shorter, either in Buffer or in the Playlist.  It played 0-2 secs and then the 17-20 seconds, then gave a Undefined Instruction  E59FF030 ,and continued to do that after a restart and play again until I cleared playlist etc out.

Second WAV when its playing normally about 10 seconds in, the exact same thing happens, song cuts out , Rockbox hangs but in this case I see more Undefined Instructions e5955b98, 00014c28, 001acc5c , also seen panic: stkov  Sceens are all white with black lettering.

On the MP3 file when I pause it 2 seconds in, play 2secs, pause it, plays 2 sec, pause , play 2secs I can make it go to almost the end before a Undefined Instruction e5955b98.
One time I did this the same , and got a Undefined Instruction at 07087C2C , white on black background.

On the WAV file when I try to do the same , around the 8 second mark get e5955b98 very often.

Some other things that happen :
1. Sometime TV static noise when controls are operated, followed by a sound cutout, and a hang of Display and Operation
2. Sometimes a hang of operation happens.
3. Seen when operatinog a Display go funny nice colors all over, like Color TV noise. Somehow the regular Rockbox menu is still in background, it is scrollable and changes the bar color and selection, hung on files selection.
4. Scrolling through menu can also hang the unit.

As you can see, a lot of intermittend issues, it sure looks like we have a unstable build, or that the build is fine but that my IPod is just a Apple Special... :)
IPod Nano 2 (4GB) model A1199 Serial YM722CZ9V8T ECM 2115  are its markings. Perhaps that may help others as well... and it could be one of the earliest units in that size.  Its something else to investigate, as that may make a difference.

Well I hope that all of this sets someone on the right direction what the problem can be, and if this can be fixed.  After all these test I think you are right, could be the too frugal settings that are used for CPU clock and Voltage..... We should have an option to tell via a configuration file to the unit, battery be damned and don't fiddle with the voltages.  I rather have a proper operating IPod with 2 hours less battery time than one that has 4 hours time, but don't work.

Although my software time is valuable, with some studying I should be able to compile Rockbox on my own, changing the source code.  I have no time for this until the weekend... :(

Let me know if there are other ideas... DR

Hi,

from your results it also sounds like your nano does not work reliable with our settings. I have build and uploaded several builds (the file rockbox.ipod only), plus a short documentation of what each build changes. Maybe you will find time to test those builds. All of them are based on svn r29983.

Edit: Forgot to mention how to test those :) Just choose one of the files, rename it to "rockbox.ipod", then copy it to your iPod's ".rockbox" folder and overwrite the existing file. Finally restart your iPod.

DutchRaider:
Thanks for that, I will work through them and let you know.  DR.

Buschel:
Any results yet?
