Hi,

I have some (longer) files (mp3/flac) which play nice with the orginila firmware
but crashes rockbox (dev build).

One file is free and legal downloadable from the internet.
It is called "One 2" by "Seconds before Awakening" and downloadable
from here:
https://archive.org/download/SecondsBeforeAwakening-One/02One2.mp3
(The other one is a personal record).

How can I handle this?
How can I fix this?

Best regards,
mcc

That file decodes normally on the Sansa Clip Zip using today's build.

sorry for the delayed answer ... I did some more tests.

It seems, that every song which exceeds a certain length (I have more of these ~20minute-pieces
on my sdcard, is affected by the problem.
Th efollowing happens:
I select the file via "files" (not via the database entry) and play it.
It starts, the sound "shows" (somehow the wrong word for something audible...;) ) no
anormalies.
Then after 3.5 minutes (another did this after 7:20 minutes) one hears something which
sounds like one would pull the earphone jack while play and .... end.
Backlight dimming works, long lines still move back and forth.
Sometimes it is posible to go back some menu items.
But often pressing a button displays [LOADING] and the Clip freezes.
A cold reset is necessary to pull the player back to life.

Same sdcard, same song and it plays fine with the OF.

The sdcard (16GB) was formatted with this command (I am on linux):
mkfs.fat -F 32 -I /dev/sdb
as root.
I used a devbuiild of rockbox.

I still hope that all this is due to a damned error I made myself
and the player is still ok.

But I dont know, how to proof it.

Is it possible, that rockbox runs with other
sdcards than the OF?

What sdcards (16GB) are proofed to work with rockbox?

Best regards and thank you for your help in advance!

Hi me,

what I did:
I removed the SDcard and booted into the OF.
I reformatted the internal flash and the sdcard with the OF.
I reinstalled rockbox with the RockboxUtility.
I populated the sdcard with the music again.
I boot into rockbox.
I did NOT change the themes settings or anything else.
I did NOT build the database.
I played a file (FLAC).
I stopps playing after about 4 minutes suddenly.
After that shutting down the player takes a long time (timeout?).
Then I (tried to) copy that file to the internal flash memory using the rockbox firmware.
This takes a llllooooonnnngggg time and ended with an write error.
I removed the corrupted file.
I repaired the internal filesystem (again).
I booted into the OF and used it to copy the file to the internal flash.
This works as expected fast and reliable.
Now rockbox could play that file.

For me it looks like:
The USB and/or flash driver of rockbox needs to be fixed.
And after that it needs to be checked, whether my sdcard needs to be replaced.

What do you think?
Best regards,
slightly frustrated

saratoga:
If reading from your SD card is unreliable, then it seems like a reasonable conclusion that something is wrong with the card or the driver.
