Ipod Nano 2G crashes and freezes

[Homer19k]

Got myself some old Ipod Nano 2G for free. Put The stable release on it and it just straight up crashes / freezes after a few minuets/seconds. Tried latest dev-build as well. Same result. Battery seems alright too.

Normal Firmware works but i just hate not being able to simply drag and drop.The whole synchronizing just annoys me. 

Anybody with the same problem?

Try checking the FAT32 file system for errors.

Tried it found no problems. The apple firmware runs without problems. I dont think its a hardware issue.

[Chronon]

Are there any actions that can trigger a crash?

Installed ROckbox again today and tested it. Cause seems completely random ,i fear, but it never plays longer than a few minuets.
Occasionally got a white screen with this error message

"undefined  instruction at 6008 pc:60083864 sp:00004bd8 bt end"

and got a Rockbox bootloader ATA Error  when i restarted

[Chronon]

Does it freeze up if you don't start music playback?

[Homer19k]

Yes it also crashes when i am fiddling around in the menue. Completely random

Same thing here .Tried latest dev builds but no luck .Player works fine in menus except when accessing debug/view disk info   or after playing music for 5-20sec   and then just froze .
 * Checked fat32 partition under win7 (ipod in disk mode ) -> no errors on partition
 * restored ipod with itunes and reinstalled rockbox             > no change
 * tried older builds ( oldest from 2017 )                            -> no luck

 Original apple software works just fine .

I also noticed that when I use external power the player works without crashing .

Works on external power is a very important observation

Is it a flaky battery, power supply, or bad settings on our end

[Thoranaga]

 Battery is in good condition .Rockbox is loaded fresh with default settings .

 With other ipod nano 2g ( wich is now dead , board issue ) Rockbox worked just fine .
