Sansa Clip+ Freezes During Playback

[Noio]

used the utility to put rockbox 3.7.1 on there

if you need a more specific build number, ask

[Chronon]

If you installed 3.7.1 then there is no more specific number to give.  If you installed a "current build" then 3.7.1 is incorrect and you should report the revision number instead.

Can you update to the current build?  There have been several improvements to the SD driver in the months since 3.7 was branched.

I've tried the stable 3.7.1, the current build and several alternate builds and none have fixed the issue.

Could you also report the revision you tested?

Just tried it with r28935 and it froze ~3 minutes into playback.

The backlight still lights up when I press a button, but otherwise the system is completely frozen and needs to have a hard restart.

Edit:

I just tried another microSD card and it WORKS. Here's the info on that:
SV08G Rev 8.0
Prod 11/2009
Ser#: 0x7126EFCC
M=03, O=SD
Blocks: 0x00ECE000
Speed: 25.0MBit/s
Taac: 10.0ms
Nsac: 0 clk
R2W: *2
IRmax: 100..25 mA
IWmax 1..45 mA


Also, tried my card that didn't work in the Clip+ and it works fine in a Fuze V2 running 3.7.1

If you need any more help pinpointing the problem, I'll be glad to help. Just want to get Rockbox running smoothly on my clip

I upgraded the uSD in my Clip+ at the weekend from a Kingston 8G to a Lexar 16G & i'm seeing this now.

I never had any issues with the Kingston, nor playing from internal memory.

With the Lexar, if i play music from it, play will freeze, usually about a minute in. I can still get into the menus & get to the debug menu, its just the playback that's frozen. I can't skip fwd/back or pause.

When it's frozen, if i browse to another music file & select that for playing it'll bring up the "loading file" box in the display & the disk activity icon at the top right will show. It's then locked up - needs a power cycle.

Booting into the original Sansa firmware & music plays back from Lexar fine (it's been running for the last couple of hours).

This is with 3.7.1 & older. Not tried any nightly build yet.

Post Merge: February 01, 2011, 01:47:01 PMJust tried the 29178 build - same thing. Playback from the Lexar froze after a few minutes.

Seems to be fixed in r29677

[keyb_gr]

I'd guess the recent patch that took out the code attempting to switch cards into high speed mode fixed this... there were several more SD related ones even earlier though. Troublesome cards tended to be 50 MBit/s (high speed) affairs.

Dear rockboxers,

I'm  reopening this. Since today I'm a proud owner of a refurbished sanza fuze v2.

I rockboxed it, filled it with my music and noticed the same bug as described in this thread.

I have a 16 gb sdhc inserted into my fuze. If i play files from the OF everything is fine, if I play from rockbox the fuze freezes after 3 to 6 songs, but continues playing to the end of the song. I have to switch the fuze off, by pushing the power button for about 10 seconds. I have all my music as ogg files, so I checked mp3 files too, they don't work either. If I play files from the internal flash everything is fine.

[micro SD1]
NCard Rev 1.0
Prod:06/2011
Ser#:0x27003963
M=89, 0=
Blocks: 0x01DD7800
Speed: 25,0 Mbit/s
Taac: 10,0ms
Nsac: 0 clk
R2W: *2

I'll try to get another sdhc card to check.

I'm a linux user and able to compile the trunk. If anyone has an idea, or a patch to try I'm willing to try it out

Thanks for reading

Greetings

Michael

update1: the song doesn't play till the end (my mistake), but they play for some time after the freeze, perhaps until the buffer is empty

Dear rockboxers,

Which build of rockbox are you running?

[mischasworld]

first tried 3.9 then actual trunk

[saratoga]

Current trunk seems to work quite well for most sd cards.  Do the files work fine off of the internal memory?

[mischasworld]

yes they do

[mischasworld]

just tried another card (this time a sandisk with 8gb), now it seems to work

[microSD 1]
Prod 4/2002
Ser# 0x022611ED
m=03, O=SD
Blocks 0x00ECE000
Speed 25,0 MBit/s
Taac: 10,0ms
Nsac: 0 clk
R2W *2

so it seems to be the card in combination with rockbox
