Sansa Fuze v2, Rockbox freezing (or 'skipping') after a few songs. mSD?

[Dumpsterac1d]

Hello!

Did a search of the forums and found a few topics that partially address the problem I'm dealing with. Recently bought an unused Fuze v2 and have been experiencing problems.

• While reading songs off of the inserted MicroSD card, Rockbox will stop playing after approximately 8 or so minutes of playback, spread across any number of songs (long songs will stop playing after about 8 minutes, and albums will stop if I skip a few tracks).
• Does not happen if the tracks I'm reading are off the internal Fuze memory.
• Happens regardless of filesize or format (FLAC, Ogg, MP3, WAV); so long as it's reading off the SD, it will skip or "freeze" playback.
• Building the database will 'freeze' in a similar way, it will stop counting at 1,200 songs or so.
• "Freezing" does not affect most other menu operations, only those involving loading up the database, or searching the SD card. Regardless of this, shutting down the player takes a "hard shutdown".
• Playback will freeze regardless if the files being played were searched through the database or through the File menu.
• OEM firmware will read all files without incident.

This glitch is extremely annoying, and I don't know what other information to give other than that I've just installed the latest stable build of Rockbox and it installed successfully and the problem still happens. Hoping I won't have to buy another MicroSD, as this one's a 32Gb and cost a couple bucks more than I want to spend on another.

I'm going to try to load songs off of the SD from my laptop to see if the SD itself is bad, but since the OEM firmware reads them properly, I'm guessing Linux will too.

Any fixes for this? Any other info I can provide to help diagnose and treat? Let me know.

Sounds like some problem with your SD card.  Try a different one.

[cats_like_micro_sd_cards]

I have exactly the same symptoms.  I'm using a Lexar 32 GB Class 10 card.  I've formatted it using SD Formatter.  I have also verified the card 2 times using the Lexar downloadable utility.

Finally, when I us the OF to read this card, I have no symptoms whatsoever.

I've ordered a Sandisk 32 GB card that's not class 10 and I hope it may resolve things.  However, I'm not holding my breath.

Is there some way I can capture a log or provide other meaningful information to FlySpray?

I want to help and not just complain...

FWIW, here's what Debug is reporting about my internal and external mSD cards:

Internal:

[microSD 0]
 SD04G Rev 8.0
 Prod: 5/2010
 Ser#: 0x23482900
 M=03, O=SD
 Blocks: 0x00753C00
 Speed: 25.0Mbits/s
 Taac: 10.0ms
 Nsac: 0 clk
 R2W: *2

External:

[microSD 1]
 LEXAR Rev 1.0
 Prod: 9/2011
 Ser#: 0xBC0370BE
 M=28, O=BE
 Blocks: 0x03BA3800
 Speed: 25.0MBits/s
 Taac: 10.0ms
 Nsac: 0 clk
 R2W: *2

I *hope* it is the mSD card. That's a quick fix.  Will post back here once I've got the new one.

Unless you can program and take a look at why the driver fails with your card, there isn't much you can do.

One further bit of potentially useful information:

I had the same mSD card in my Clip+ running RockBox 3.9 and used it for a year without incident.

The exact same mSD spent many hours on long-haul flights, so I feel that it's been adequately tested in that device.

I feel stupid for omitting this information in my first post  -Perhaps there are some differences in the drivers either between the devices or between the versions that could be identified.

Also, I ran the card as-is, pulling it straight out of my Clip+ and tried to use it in the Fuze V2.  -It was only after the freezing behaviour that I decided to try formatting the card.

I'm afraid that I tried my hand at writing code many years ago and discovered that I don't have the patience (or intelligence?) for that.  So, you're right in saying that I likely won't be examining or modifying the driver anytime soon.

I will try version 3.9 on my Fuze V2 and see if that makes any difference.  If it does, that could be interesting.

Well, installed RockBox 3.9.1 and I thought it was OK...for a while.

After 11 tracks / ~ 118 mins, it locked up using the external Lexar mSD.

I'm looking forward to the delivery of the Sandisk mSD.

There is some other coverage of this here:  http://www.rockbox.org/tracker/task/12658

I find this interesting also:

"I don't know exactly how long this problem has been going on but it has been getting worse. Before the 30,000th SVN release, perhaps somewhere around 28000, I would be getting crashes occasionally with the V2s but nothing like this."

I continue to wait for my new mSD card.  I'm starting to wonder about the Amazon merchant... I can get a full-sized medicine cabinet for the bathroom shipped faster than an mSD card!! 

[cats_like_micro_sd_cards]

Right, problem = sorted.

With the new Sandisk 32 GB Class 4 mSD inserted in the Fuze V2, I am unable to reproduce any of the freezing symptoms whether skipping back & forth between tracks or simply letting it play out over an extended interval.

I re-flashed back to stable release 3.12 and also it's good like that.

FWIW, here are the debug specs for the new Sandisk Card:

[microSD 1]
 SU32G Rev 8.0
 Prod: 9/2012
 Ser#: 0x72434287
 M=03, O=SD
 Blocks: 0x03B72400
 Speed: 25.0MBit/s
 Taac: 10.0ms
 Nsac: 0 clk
 R2W: *2

So, it looks like Saratoga's advice: "Sounds like some problem with your SD card.  Try a different one."  is the best advice for this bad behaviour.

Will post back if anything comes up, but after some hours of playback, I would have expected something to have gone wrong by now with the other mSD card.

I hope this helps somebody avoid some frustration / disappointment.
