Sansa Clip+ Freezes During Playback

[funman]

Can you try this build ?

It's r28095 with sd_enable() effect removed so SD is not disabled when not in use.

This might have an effect on battery life but if the problem is disabling SD and shortly after re-enabling it you should notice it.

Hi, thank you for the new build    unfortunately it's the same result    the first 4 songs were fine, but when I skipped to song 5 it froze again (I let each song play for about 15-20 seconds then press 'next').

[funman]

Does it always crash on the same song? (It could be that rockbox doesn't like this file for a reason..)

Else I'm out of idea and if FlynDice doesn't give a hint I'm gonna blame the card even if it works fine with the OF ...

[joe4268]

Nope, it's on shuffle and the song it crashes on is different.

I exchanged the card yesterday and the same thing happens (straight exchange, same product -- rules out a single defective card, but it may be something about the whole line of the specific card I have).

I guess I'll just have to suck it up and buy another 16gb card!

Hi,

I have more or less the same problem (freeze, etc)

reading from my SD card cause RB to freeze (cannot update db or simply read a file)

changing the SDcard to another solve the problem.

BUT this card is correctly read under the OF on the same device or on other device (ex: sansa e280 + RB 3.6)

here is the "disk info" about these cards :

I hope it could help to improve SD card support on RB

Same problem here : playback freeze when playing from microSD or just browsing microSD.

Target : Clip+ 2GB with a Transcend 8GB class 2 microSD card.

It looks like you posted the wrong information.  The disk info you have posted is from a 2G disk - possibly your internal drive (microSD 0) instead of the 8G microSD card (microSD 1).  When you look at disk info, it displays the internal by default.  You must press the select button to switch to the microSD card - the top line of the disk info display should show microSD 1 when the microSD card is properly selected.

Oh, sorry, didn't pay attention. Here's the right information for the Transcend cass 2 8GB microSD card :

By the way, I wanted to add that rockbox bootup also freezes if the card is inserted and contains the last played song. I see no main menu, but only the RB logo stuck on the screen. So I have to remove the card, force shutdown and turn the player back on without the card to make it boot correctly. Is anyone else experiencing this?

My card also still makes the Sandisk OF freeze as well. And it looks like i'm not the only one :

Very annoying.
Cards of very different brands may work, and may not. However, interestingly, nobody is complaining about Sandisk cards.

So are there that many bad quality Kingston, PNY, Transcend, Kodak/Lexar etc cards ? I don't think so and I'm afraid that Sandisk is not in a hurry to fix that bug (if such there actually is).

Anyways, any thoughts/ideas/workaround/progress/whatever about this issue ?

PS: I can set up a build environment on my Linux box to try patches.

If your card is failing in Rockbox and in the OF, there is not much we can do about it.

I'm experiencing a similar problem on my Clip+.

However, I have on both the internal memory and the microSD card.

The freezing only happens when I have the Clip+ on 'shuffle', not when I play in regular order. It happens with both MP3 and FLAC and usually after 3 or so tracks. The odd thing is that the playing time for the track it freezes on will be higher than the length of the track.

When it freezes and I press a button the display turns on but it won't respond to any other buttons.

Before moving to Rockbox 3.7 I was using an old version from somewhere in july, so I'm afraid I won't be much help to determine when this behaviour crept in.

I'm experiencing the same problem. The system will freeze and require a long hold of the power button in order to restart when I play music off the microSD. It plays fine in the OF.

Here's the disk info on the microsd:

I've seen this problem posted quite a bit, so I don't think it's an isolated incident...

[murso74]

my problem is with a samsung 16gb card...   sometimes it will play a few songs but usually freezes after one or less

[Noio]

happens to me as well, works fine in the original firmware. i'm using a sandisk 4gb, so it's not just the other card makers

Could you also report the revision you tested?
