Sansa Clip+ Freezes During Playback

[joe4268]

Hi,  new Sansa Clip+ owner looking for some rockbox love 

I am having an issue where, when playing from a mSD card, the clip freezes requiring a loooong power press to reset.  Playing from internal memory is fine, and the original software can play from the mSD card fine as well. 

Basically, within the first 5 or so songs, when I skip to the next song it'll freeze the unit.  The only setting modification was to turn shuffle on.

Here is what I'm using:
    * Sansa Clip+ 2GB with Rockbox r28085
    * 16GB Kodak (Lexar) Micro SD Card, Class 4

Here is what I've tried:
    * reformatted mSD card with 'SD Formatter'
    * checked mp3s for problems (utilities: 'Audio Tester' and 'MP3 Checker')
    * uninstalled rockbox, reflashed original sandisk firmware, reinstalled rockbox

Unfortunately nothing I have done has had any impact.  Does anyone have suggestions?  Thanks!

Can you try a different card?

[joe4268]

Unfortunately not at this time... I'm trying to find a buddy with a mSD card though.

Can you try to copy files between internal storage and µSD ? (in both directions)

[joe4268]

I'm not sure if I fully understand what you mean.  I've got over 8GB on the mSD, so I couldn't do a transfer to the 2GB onboard storage.  If my steps below don't work, I'll reduce my mp3 files and perform your suggestion.

Fortunately I just realized that my wife's BlackBerry has a mSD card... I'm in the process of loading it up and will post the results within the hour.

You don't have to copy all of them, just move a few back and forth a couple times and see if it freezes.

So the new mSD card (Kingston 8GB) seems to work perfectly with Rockbox so far.

Any reason why the Kodak would work fine with original fw but not rockbox?  Would this be incompatibility with the brand/card combo (i.e. an exchange of the card at the store would likely not help)?

[funman]

How are both cards advertized ? (especially "class")

Also can you write what is in system -> debug menu -> disk info for µSD (it's drive 1), for both cards?

[joe4268]

Both are class 4 cards:

Kingston 8GB (Good):
SD02G Rev 8.0
Prod: 5/2010
M=03, 0=SD
Blocks: 0x003A0000
Speed: 25.0MBit/s
Taac: 15.0ms
R2W: *4
IRmax: 100.80 mA
IWmax: 100.80 mA

Kokak 16GB (Bad):
LEXAR Rev 1.0
Prod: 5/2010
Ser#: 0x0000013C
M=28, 0=BE
Blocks: 0x01DDE000
Speed: 50.0MBit/s
Taac: 10.0ms
R2W: *2
IRmax: 60.20 mA
IWmax: 10.45 mA


Thoughts?

Kingston 8GB (Good):
Blocks: 0x003A0000

That adds up to 2GB with 512 bytes blocks, so perhaps it's using 2048 bytes sectors ? O:
Anyway if works fine so..

Kingston 8GB (Good):
Speed: 25.0MBit/s

Kokak 16GB (Bad):
Speed: 50.0MBit/s

Perhaps the card doesn't like high speed mode, do you have a build environment to try patches?

Sorry, I'm new to this and don't know what that means!  I'd be glad to test things out though if instructed.

[SpawnHyuuga]

Joe, it deals with your Operating system and whether you can build Rockbox patches, either custom or in Flyspray.

[joe4268]

Ahh, that seems a little out of my league unfortunately (building patches)

[funman]

Hm ok

Did you try to copy a bunch of files to/from the bad microSD?

Just copy a big folder (a coupe of hundreds megabytes would be fine), that could give a clue if the problem only happen when using both storage and playback at the same time.

FlynDice might have an idea but he's not really been there recently (he's quite busy afaik)

I tried the copy and it worked perfectly on both cards... only playing (changing songs) is causing my freezing problems in RB.
