Ah--got it.

Here's a new bootloader with the new 1.2.13 firmware: r25738-100427-sansaclipplus-01.02.13-dual_boot.zip

Old one is still here: r25316-100324-sansaclipplus-01.02.09-dual_boot.zip

Thanks! I get a better night's sleep by listening to this in flac, set to repeat until I wake up: http://sn.im/deltasleep

The original firmware is only good for about 6 and half hours before the battery dies. I haven't tested rockbox's runtime, but it's definitely a lot better than that. It would be nice to be able to lock the unit though, which working RB builds don't do yet. I hope sansa has been working on their flac codec. I'll do a flac playing battery rundown test of the new Sansa firmware within the next couple of nights and see if the latest version helps.

Not yet. I'm afraid it's much worse right now, because the Clip+ runs stable in boosted mode only, which unfortunately eats up a lot of power...

Are you talking about the latest unstable version they are currently working on, or the latest usuable? I use v25348 and get at least 8 hours from playing flac files, battery reading over a third after 8hrs 10m. Even if v25348 is battery compromised at the moment, it's definitely better than the 6 and half hours I get from Sansa's OF.

I think a month ago (when boosting was briefly stable) someone measured about 18 hours for MP3, and I would expect flac to last longer then that.

Then the CPU ran statically at 120MHz (I think) and now it's either 240MHz (boosted) or 60/240MHz (dynamic, and crashy).

Comparing to Fuzev2, battery life on mp3 should drop by 4 hours or so (comparing 120MHz and 240MHz)

18 hours on a Clip+? That would be stunning. I don't get any more than ~6 hours of MP3 playback with recent boosted rockbox builds. Maybe it's the crossfeed I'm using?

[saratoga]

If you force the player to be boosted all the time you'll get much worse battery life.

I tried the new bootloader. I just got a black screen after the "rockbox" boot screen. I had to press the off button for a long time before I could boot into Sansa and reinstall OF. I had kept the .rockbox folder from the older version. Did I do something wrong? My Clip+ is the 8GB version.

[dfkt]

It works fine for me, on an 8Gb Clip+ as well. Sometimes it hiccups, a few times I had total lockups with the old bootloader as well. Did you try an older, more stable firmware build?

[Trondis23]

Yes, it is an old "unstable" build. It used to work fine.

[dfkt]

The new bootloader works fine for me as well, with firmware r25407. Same as the old one, actually. Been listening for quite some hours with the new one, without lockups. Did you give it a 2nd try?

[Trondis23]

I will wait before I try again - I got a bit scared...

[Timar]

I also get sometimes startup-crashes with the new bootloader. It shows the rockbox screen and freezes. Never had that before.

[dfkt]

You're both right. I've actually had a new firmware build running, I didn't revert to an older, more stable one, as I thought I did. I'm getting a black screen now every time. I compiled an even newer revision bootloader, but there's no difference. Seems something's broken for the moment. Those bootloaders indeed don't work with older firmware revisions, but do work with newer one - but those are unstable, so there's nothing useful I can do.

[dfkt]

Here's the 'official' v1.0 bootloader: v1.0-bootloader-sansaclipplus-01.02.13-dual_boot.zip from this source - it's basically the same I posted before. It runs great with the current revision r25747, without crashes. It doesn't work with old builds due to the change of the CPU frequency handling - so you have to use a new build. r25747 doesn't crash for me - funman suggested boosting the CPU frequency in the system>debug menu (I've boosted it to 1), which has been stable for me so far.

So either you run the old bootloader and an old firmware build, or the new one with new firmware and boosted CPU - both variants run 'stable', but mixing old and new doesn't work.

[funman]

I've put a custom build on my ISP homepage, can you give it a try ?

I had one crash with it but it seems much more stable than current builds, so I'd be interested to know how it works for other people.

It's based on current SVN + a patch which could give a hint on how to fix the problems properly. And it should work with any bootloader.

No need to force CPU boosting with it (the patch affects the function which changes CPU frequency so if you force boosting then the patch won't run at all).

[dfkt]

Funman, your build ran stable for over an hour so far, playing a mix of LAME VBR and Vorbis files. Yay!

EDIT: two hours and still going...

argh! I cannot read this thread.

Must... resist... urge... to... install... Rockbox....
