playback crashes on 5g (60GB) ipod

<< < (2/3) > >>

Febs:
Do you mean a 30 GB in a 60 GB's body?  It sounds like that is entirely possible.

argent:
A 60GB hard drive, with 32MB of RAM.  If that's the case there isn't really anything I can do about it anyway.  

So the question would be, how can I check the amount of RAM in it?  I'm not entirely opposed to the option of opening it up, but I'd need to know what to look for.  Still, a software solution would obviously be best.  

If nothing comes to mind, though, it's cool.  Whether or not I actually have 32MB of RAM, it's for all practical purposes 32MB, so it's really academic at this point.  

David Marsh:
yes i have this problem.  it think it because the cpu is now running at 78Mhz and not 75Mhz.

I was running a build from 22 Jun 2007 and installed 3 July 2007.  then it started crashing quite soon into a track.  i might be lucky and get 3 tracks before it crashed.  previously it didnt crash at all.

I have reverted back to 22 jun 2007 build and the CPU freq is back to 75Mhz.  You can check this in the debug menu and select 'CPU frequency' option.  You can also see this in 'view audio thread' during which on the 3 july build it crashed with:


--- Code: ---Data abort
at 00030784
--- End code ---

Is the cpu meant to be runing faster?  is it just reporting an incorrect value?  

soap:
The speed change was intentional and part of changes to the PP5020 code made to correct the crashing on iPod 4th gen / Mini 1st gen targets.

David Marsh:
Thats all very well but if it causes 5g ipods to fail then it needs to be backed out.  I am currently running 1-july-2007 build and that seems to be holding up quite well right now.  This was the build before any CPU changes were made.  I will roll forward each daily build until the symptoms reappear then we can narrow down the exact cause, and hopefully find a solution.  The builds for the 4th & 5th were causing crashing, so effectively I only have to install 2nd and 3rd july daily builds to find the one that causing the problem.
