Sansa e200 4gb V1 scroll wheel problems

[marsrover]

Before I get the answer of clean it. I have.
The wheel works absolutely fine in the original firmware. But in rockbox, sometimes it works, sometimes it refuses to move. Most of the time turning it off, booting into the original firmware, then going back to rockbox clears that problem up. But recently that hasn't been working. I have tried removing rockbox completely and re-installing it. Bootloader and all, still to no avail.
Any ideas? Oh, I can't see the debug menu because I can't use the scroll wheel to get to the debug menu. So I have no idea at all what it's doing.

you should post what rev you are running,   try another rev

3.9.1
Shouldn't the most recent one work the best? I don't see how that could be a problem.
The bootloader is from 09' but I assume no one has updated that in a while.

Since i've never heard of this is probably something wrong with your hardware.  If cleaning it doesn't work, you may just have to use the OF.

It worked fine for a long time. (years)
I'll try the old firmwares.
hehe, um, is there a GUI for the old versions?
I REALLY don't want to compile it...

Did it stop working when you updated?

thanks

It started slowing down, then it just got worse with each update.
While I was cleaning it, the really thin part of the metal that does the contact kinda broke off.
They were all folded and stuff. The harder part of the brush is still there, and it works fine in the original OS.
So is there some setting I can change in the code to tweak the sensitivity or something?

(ps, the link you gave me leads to instruction manuels, not the linux rockbox utility)
EDIT: I'm just stupid, found it.

You could take a look at the logic used to detect changes in the wheel sensor state.  Its possible the OF does more error checking that makes it more tolerant of a failing sensor.  The driver should be somewhere in firmware/target/arm/sansa IIRC.

I don't think you can use rockbox utility to install old builds.  You don't need it anyway.  The link I gave you is to a copy of each old release.  Just download it and extract it to your player.

older versions refuse to boot.
Bootloader problem? Due to some random I/O errors I'm re-formating the entire drive.
Will attempt again after that.

I really don't want to give up rockbox, is there a build that has the up and down keys that make the selector go up and down instead of doing other things? (could move up and down only when not on the now playing screen)

If it just started happening, and it's not working with older versions of Rockbox that used to work, and you admit to breaking bits of it while cleaning it, it sounds like it's the beginnings of hardware failure. The fact that the original firmware still works suggests that Rockbox may be overly sensitive to whatever's been broken, but I would recommend planning for the player to show further signs of failure in the near future, especially since you seem to have had other issues with it such as the IO issues.

[marsrover]

Well, memory doesen't last forever. (though it should have lasted longer)
But really the up and down selector would fix it just fine. That's all I need.
