Sansа Clip Zip - Improve battery life
saratoga:
Mihail: Could you post the most up-to-date version of your patch? I'd like to do a little testing but I'm not sure where you are at with the code right now.
Thanks.
Mihail Zenkov:
I don't work on this patch last few months.
I have same problem with usb like in keyb_gr last posts. But ...
1. it hard to reproduce - it crash one time for 10-30 connect/disconnect and probably only when we write something
2. not sure is it one problem or few - most time player just freeze with screen on, but one time I have hard lockup - in this state player have screen off and can't be reset by power button, but disconnecting battery (or drain battery like keyb_gr do) help.
3. probably it not related to this patch
In any case I want try debug it. Is rockbox have easy way to write/append in to file (log)? I want find in which function player freeze.

I guess it is time for me to report back. I have been using Mihail's version: 983c808M-150809 on my clip+.
During regular usage I have not seen any quirks. I am not using any fancy EQs though, just replaygain, sometimes treble & bass, timestretch in podcasts. Formats: mpc, mp3, flac, opus
But I had three incidents in the context of USB:
2 times after safely removing the player (Win7 Pro) I still had the USB logo in the background and a rectangular box over it saying "loading " (I don't remember if it said firmware or file). I had to press power for several seconds for it to recover.
One time when connecting to USB there was a screen saying "prefetch abort ...".
As this happened over the past 2-3 months, I still consider it usable for me. I did have USB problems in-regularly with other builds before too.
P.S. I usually power the player on before connecting to USB.

Your patch ('amsv2_scaling_v9.patch.txt') deactivates the functionality
of the "hold" button on Sansa Fuze v2: It is simply not functional
anymore, if I operate it it behaves just as if it has not been operated.
Without the patch, it works.
I am using rockbox version ad5e5c4M-151204 (according to the menu item
"System" -> "Rockbox Info" on the device itself),
it is compiled from the rockbox-source from

Can you check amsv2_scaling_v9.patch.txt + rockbox-gui_boost.patch.txt?
http://forums.rockbox.org/index.php/topic,48549.msg234910.html#msg234910
P.S. I also recommend use rockbox-usb.patch and rockbox-restore_irq.patch if you use amsv2_scaling_v9.patch.txt.
