Plus the fact that it happens on the Fuze v2 but not Zip/Clip+
As I mention before Zip also affected but in another case. If I remember right, it was when I try change voltage on pause/play.

But since it depends on when you do it, that sounds like more of a conflict with the button driver I think?

Not sure but possibly. What about clipv2 problem? Can you test it with my "irq" patch or you already have solution for it?

I bought the fuze ~5 years ago as a refurb, so the battery is somewhat aged, but I don't use it regularly. Working horse for commuting is a clip+.

If I remember correctly runtime with the 3.13 release (more than a year ago) was ~20h.

Tested with the new fresh sansa clip+. Unstable with current patch set. Solved problem by increasing CVDD2 to 114.

Which patch (link?) do I apply on a Clip+ daily build to see the effect of these developments?

The latest in the gerrit task I believe, although you'll have to remove the changes to as3514.c as those are already committed.

Updated builds:

http://web.mit.edu/mgg6/www/rockbox-clipv2.7z
http://web.mit.edu/mgg6/www/rockbox-clipplus.7z

Is this compile the most optimized for clip+ as of today?

No it doesn't have the DMA changes or the I2C fix.  I haven't had time to work on this lately though, so you'll have to grab the patches and build yourself.

Hi all,

I'm trying to patch last build e606ee4 for my clip+ with patch 7 (http://git.rockbox.org/?p=rockbox.git;a=patch;h=471ced2d0f1df1f6e53824197c93e52563fdac3a;hp=193c5df75d3b6d9e3442e42fa26fd8ccc4c5e3aa) to improve battery life, but I get the following:

patch --dry-run -p1 < "rockbox.git-471ced2d0f1df1f6e53824197c93e52563fdac3a.patch"
checking file firmware/drivers/audio/as3514.c
Reversed (or previously applied) patch detected!  Assume -R? [n]

Hunk #1 FAILED at 33.

Is the patch I'm applying not compatible with the last build e606ee4 or I'm doing something wrong? Where can I download a patched build for clip+ ?

Thanks a lot for your help

I quickly synced that file (was only one line changed).  I can't login into gerrit at the moment, but here is the patch:

I also committed the DMA patch, so that should give everyone a very slightly lower CPU usage.  It works for me and in theory is correct, but I'll watch for any problems.

Yes I'll commit those shortly.  I can't login into gerrit though, so I can't close the tasks.
