#rockbox log for 2014-08-14

00:01:59TheSevendoes it actually receive IRQs?
00:02:43 Quit ender` (Quit: The sum of intelligence on the planet is a constant; the population is growing.)
00:04:59franklinWhat do you mean?
00:07:38TheSevenis INT_TIMERA actually being called?
00:07:53franklinYeah, it's making the beeping/buzzing noise
00:09:38 Quit robert__ (Quit: Page closed)
00:13:53TheSeventhat doesn't mean that the function is actually being called
00:14:11franklinSo how do I tell if it's being called?
00:14:19TheSevenput a logf into it?
00:14:30franklinWhere does logf output go?
00:17:43franklinTheSeven, wait! I left out one TCCMD at the top
00:17:55franklin(now TACMD)
00:18:49TheSevenit logs into the logf buffer
00:18:57franklinwhich goes where?
00:20:05franklinto a file?
00:22:40[Saint]When this is actually functional, there's a truly obvious candidate for exposing the piezo via the plugin api - metronome
00:23:50[Saint]Shouldn't be difficult for me to whip up a nice 'tick' and 'tock' sound.
00:24:22[Saint]The issue there is the piezos all sound fucking wildly different on each iPod for some reason.
00:24:30franklinI have already in my local branch
00:24:38[Saint]I have /most/ of the iPods
00:25:22franklin(adding piezo to metronome, that is)
00:25:47***Saving seen data "./dancer.seen"
00:25:57[Saint]I have at least one of every model except 2G and Mini 2G
00:26:18franklinbut why?
00:26:29[Saint]Why not?
00:27:06franklinI would say l*l
00:27:16franklinbut gevaerts would most probably kick me :D
00:27:38[Saint]If you think that's extreme - you should see lebellium's collection.
00:27:58[Saint]He has something in the range of 200 DAPs.
00:28:11franklinI have two: ipod classic and my late c200
00:28:44[Saint]He's a collector/reviewer/DAP historian.
00:29:31franklininteresting job... but move over to #rockbox-community
00:29:36[Saint]I actually /do/ have an iPod 2G and a Mini2G, but they're both nonfunctional.
00:30:23[Saint]The iPod 1G is the only one I don't have at all.
00:30:42franklinWell, I'm gonna wait for this to build... cya later
00:33:04 Quit dfkt (Ping timeout: 260 seconds)
00:33:37*[Saint] can't figure out how the hell the skin engine is keeping track of the bar position for the 3 %St bars he has running across the entirety of the runtime duration, entirely independently of the setting they supposed to represent.
00:33:49[Saint]It fucking boggles me.
00:35:19[Saint]I'm having a difficult time with the glue code needed to get the %St bar's touch areas to set the config.cfg value.
00:35:50[Saint]...I guess I need to look at setting_set and the other touch areas.
00:36:40 Join dfkt [0] (
00:36:40 Quit dfkt (Changing host)
00:36:40 Join dfkt [0] (dfkt@unaffiliated/dfkt)
00:38:46[Saint]On the very first run of the wps after startup, it gets the value its supposed to represent right (verified by scattering debug text everywhere in the theme), but when I pick the scrubber handle up and drag it around the value doesn't change, a quick kook last night told me that's expected, that's fine.
00:39:17[Saint]What I can't figure out is how its keeping track of the bar position independently.
00:39:38[Saint]I don't really need to know to fix it either, I'm just curious.
00:41:30[Saint]I kinda backed myself into a corner. I need to either fix it up, convince someone else to do so if I can't (a possibility indeed), or carve out a huge part of the overflow menu in my theme and comment it off for the future if/when its a possibility
00:42:54[Saint]Actually...I could probably fudge it with a huge array of touch areas using setting_set but I'd hate myself for such a hideous workaround.
00:45:37[Saint](It would need a fucktonne of target dependent checks because not all targets have the same upper and lower bounds for some settings and thinking about writing such ugly code makes me anxious...uuugh)
00:47:00[Saint]Shit. Sorry.
00:51:26 Quit bertrik (Remote host closed the connection)
01:00:31[Saint]With SDL2 we could use hardware accelerated OpenGL ES via the GPU on the raspberrypi.
01:01:02[Saint], not in a windowed mode though.

01:15:04*TheSeven pongs
01:15:42franklinOK, so where were we?
01:15:47franklinOh yeah... logf
01:17:18franklinI recompiled with logf enabled, but after a hard reset (MENU+SEL), I can't seem to find a log file anywhere
01:17:52TheSevenwell you have to dump it before the reset
01:19:00franklinWhat function?
01:20:08franklinah logf_panic_dump
01:20:43TheSevenright, if you want to check if something is hit at all, you could just panicf there
01:21:06franklinthat always works :D
01:21:10*TheSeven is too tired
01:21:30TheSeven1:20 am here, going to sleep now...
01:21:43franklinSure... catch you later
01:22:06franklinBut no panicf
01:29:00 Join uwe_ [0] (
01:40:46JdGordon_[Saint]: you need to get me when im home and not playing civ5 :p
01:40:50JdGordon_shold be simple enough to fix
02:00:05[Saint]JdGordon_: OK, well I'll keep trucking and see if I can figure it out myself for now, and from a theme perspective I'll keep pretending it works.
02:00:39[Saint]I'll definitely speak up if (more likely when) I get stuck.
02:01:57JdGordon_the slider position stays where you set it even if you leave the wps and go back in?
02:03:33JdGordon_[Saint]: wait, are you 100% sure the setting isnt changing?
02:04:10[Saint]config.cfg never gets updated.
02:04:22 Quit franklin (Quit: Leaving)
02:04:56JdGordon_ok, but what about the setting in the menus?
02:05:03[Saint]And, yes. The slider position is kept across the entire runtime duration if I change it.
02:05:24[Saint]And no, the value displayed never gets updated either.
02:05:44[Saint]I added textual debug statements printing off the setting value to check.
02:05:56[Saint](in the wps)
02:06:20JdGordon_can you change the setting and then see what the value in the menu is?
02:06:32JdGordon_i think it is actually changing
02:06:47JdGordon_update_setting_value_from_touch() just needs a settings_save() call
02:08:27[Saint]Hmmm. Sorry, what? Change the setting from the actual menu, and then check the bar position and the printed debug value of the setting in the overflow menu of my wps?
02:08:47JdGordon_other way around
02:09:05JdGordon_change the slider in the wps, then check the value it show in the settings menus
02:09:25[Saint]Oh. Right. Yeah. Doesn't change.
02:10:10[Saint]I'm printing off the value if the setting in the wps itself so I don't need to (in theory) check it from the menu.
02:10:22[Saint]But when I do, it remains unchanged.
02:10:25JdGordon_I asked you specifically to check it in the menus thoguh
02:11:06JdGordon_thats pretty suspect then... the code looks like it should change in the menu
02:12:34[Saint]OK. Right. Your correct. There's a discrepancy between the actual HW and the SDL app it seems.
02:12:39 Quit ZincAlloy1 (Quit: Leaving.)
02:13:07[Saint]On my test device, it *is* updated in the menu. But config.cfg remains untouched.
02:13:34JdGordon_yeah, it needs a settings_save() call
02:13:41JdGordon_see above
02:13:48JdGordon_add that and if it woks I'll push
02:14:01[Saint]It may be my SDL app threw a spanner in the works. My apologies.
02:14:13JdGordon_that shouldnt happen :)
02:14:25JdGordon_hurry up with the 1080*1920 version!
02:14:26[Saint]You were quite correct about expected behavior on real world hardware.
02:15:45[Saint]And, yes, will do. In theory, my changes presently should make it /somewhat/ usable on and target with a resolution no smaller than intended.
02:16:19[Saint]Positioning by percentile is *fucking* cool.
02:16:25[Saint]It helps a lot.
02:16:41JdGordon_send me a zip and I'll test it as it is

06:02:23[Saint](I recompiled my sdl-app and its behaving normally, and matching real hardware again, btw - not sure what was up with that...)
06:03:34[Saint]so the values printed in the wps move accordingly with the bar, and the setting value is updated in the system menu, buit its not actually _applied_.
06:04:15[Saint]even with adding settings_save(); to 299 on skin_touchsupport.c
06:05:34[Saint]my apologies for the sdl-app initially causing me to state a mistruth.
06:15:35 Quit Strife89 (Ping timeout: 272 seconds)
06:18:36JdGordon[Saint]: and settings_save() is actually being called?
06:18:44JdGordonthat should force a settings write
06:20:00[Saint]it looks like it /should/ be:
06:20:14[Saint]I assume that's correct.
06:20:18[Saint]looks right to me.
06:20:36JdGordonyeah, thats correct
06:21:30[Saint]the same thing is happening with the context menu's "reset setting" feature.
06:21:39 Join ploco [0] (dce9b7f9@gateway/web/freenode/ip.
06:22:09[Saint]it updates the value in the settings menu, and its visible in the wps in my debug stuff and overflow menu settings, but its not actually _applied_.
06:22:13ploco[Saint]: update_setting_value_from_touch in option_select.c.
06:22:34[Saint]aha - you glorious fucker. :)
06:24:06[Saint]I, no - hangon. What?

06:27:25[Saint]ah - to fix the "reset settings" not applying properly?
06:28:00plocofor bar updated but not apply issue
06:28:32JdGordondon't do that :)
06:28:51JdGordonget it to call val_to_selection() and use the returned functino pointer
06:29:11JdGordonbut no that shoutldnt stop setting_save() applying everything
06:29:23plocoits a ugly hack i did, I know its very bad and never put on gerrit
06:29:26JdGordon[Saint]: which setting are use testing with?
06:29:39JdGordonmust be the sound ones?
06:29:46[Saint]bass, treble, balance
06:31:41JdGordonthose shouldnt need the callback to be called to get written to the .cfg
06:31:50JdGordonbut they do ned it called to apply the change
06:33:55[Saint]oh, shit me. yes, it is updating the .cfg now after adding settings_save(); to skin_touchsupport.
06:34:00[Saint]but its not audible.
06:34:17[Saint]you're quite right.
06:34:17JdGordonyes, the callback needs to be called
06:34:29JdGordonas ploco pointed out (clever guy :) )
06:34:32[Saint]so, that's half the bug taken care of. I'm not sure I follow on the other half.
06:35:37JdGordonin update_setting_value_from_touch() call val_to_selection() to get the callback function, then call it
06:36:04plocoI knew this since one year ago. was making a theme contain EQ bar in WPS. but nvm cause I'm not gonna do the workaround anymore. thinking go native for real this time.
06:36:06JdGordonget_setting_info_for_bar calls it but doesnt use the returned function
06:36:59JdGordonor add a nicer way to get the callback

10:29:23JdGordon[Saint]: if you give me a skin preview i'll fix your setting slider bug
10:34:35[Saint]don't mind the draw issues in the overflow menu - I /think/ I have a workaround for this.
10:35:53[Saint](my idea if to make variable set/increment/decrement trigger a full wpsupdate - is that too ugly?)
10:36:23[Saint]play/pause does a full wpsupdate, so, I guess not.
10:36:57[Saint]alternatively I could create two fullscreen conditional viewports and juggle them to force a fullscreen update.
10:37:31[Saint]alternatively alternatively, centering text in viewports would allow me to /disguise/ the issue.
10:37:46[Saint](line height, not horizontally)
10:39:34[Saint]let me know if you have any idea on the right way to handle the draw issues you'll undoubtedly see in the overflow menu backdrop segments.

11:55:16[Saint][7]: would you have any objection to me disabling GUI boost onthe Classic (and N2G?)?
11:55:27[Saint]neither of them require it.
11:55:48[Saint]its aimed at the PP ipods, and both the N2G and Classic inherited it via config c/p.

11:56:53[Saint]Video, Color, Photo, 4G, 3G, ...etc. all require it else the lists become very choppy.

12:27:05[7][Saint]: I seem to remember that the UI was sluggish without it a few years ago on nano2g
12:27:32[7]but if you can't find any regressions (also check USB access etc, that might only work properly when boosted due to system bus bandwidth reasons), I'm fine with it
12:27:40[Saint]I don't seem to find any issue with it.
12:27:52[Saint]but perhaps people are having issue with overly complex themes.
12:28:20[7]bcobco: can you test g#897 for regressions?

12:28:38bcobcosure. but
12:28:41[Saint][7]: if USb access needs boosting, that needs to be handled entirely seperately, and, AFAIK, isn't now.
12:28:51[Saint]I'm not disabling boosting altogether,.
12:28:55[Saint]Just the GUI boost.
12:29:11[7]sure, I'm just saying that disabling that might expose other problems
12:29:18[7]so it needs careful testing
12:29:34[Saint]I'm not sure how it could cause an issue with USB though...
12:29:44bcobcobut is there any /.rockbox directory ?
12:29:54[Saint]That would've presented an issue _long_ before now if it was relevant.
12:30:16[7][Saint]: unless GUI boost, for some reason, boosts before entering the USB screen
12:30:26[7]not sure if it does, but it's something to watch out for, just sayin'
12:30:42[Saint]...not that we need to worry about USB on the N2G.
12:30:48[Saint]In fact, it shoul dbe disabled.
12:31:09[Saint]It just panics and fucks itself anyway.
12:31:34bcobco[7]: is this one_?
12:31:43[7][Saint]: even with my patch?
12:31:57[7][7]: no, I need you to test a patched build
12:32:08[7]no, the USB designware patch
12:32:13[7]the one that needs the bitfields removed
12:32:50[Saint]It did the first time I tested it with a binary you gave me. But that was ages ago. I haven't been able to compile it 'cos GCC.
12:32:59[Saint]removing those bitfields is on my todo list.
12:33:06[Saint]but someone is welcome to beat me to it.
12:33:16[7]check with user890104, he might be working on it already
12:33:43[7]bcobco: I can make you a build to try in a few minutes
12:33:43bcobcogime a link to a patched build and im testing if
12:33:58[Saint]I needed to expand the stack WAAAAAAAAAAAAAAAAY more than I felt comfortable with to get it to stop panicing on USB plug.
12:34:06[Saint]like, a factor of 8.
12:34:14[7]USB stack or main stack?
12:34:19[Saint]USB stack.
12:34:53[7]huh? that doesn't make sense at all
12:35:02*[Saint] nods
12:35:13[7]especially only on one of two targets, sharing the same code
12:35:52[Saint]I need to setup the toolchain for emCORE again.
12:36:16[Saint]I had it going, but Ms. [Saint] accidentally wiped out my shared dev storage. :-/
12:36:42[Saint]And I haven't bothered replacing it because it gave me an excuse to not bother fixing issues that are presented by your patches.
12:36:58[Saint]...not that I've been rushing to do that. ETIME> :_/
12:37:42[Saint]The TNT toolchain seems to be quite a bit more lenient (but produces slightly smaller binaries).
12:44:00[7]bcobco, [Saint]: ^
12:44:17bcobco[7]: ok

12:57:15fs-bluebot3Gerrit review #913 at : 3Call the setting callbacks from the touchregions by Jonathan Gordon
12:57:47[7]bcobco: hm, those builds have reworked USB and hard disk drivers, and better charging / power detection code
12:58:24[7]in the hard disk area, mostly the drive detection and initialization has been changed, not the actual data transfer code
12:58:31bcobcoi will try to connect to a simple usb charger, i will see if rockbox tries to mount (it should not)
12:59:01[7]so in general this build needs USB testing, drive compatibility testing, and charging state detection testing, including firewire charging if possible
12:59:09[7]I guess you've already tested everything that you can :)
12:59:42bcobcocheck this
13:00:01bcobcoDivide by zero at 0805CF04
13:00:18[7]hm, nano2g and classic don't have USB host detection yet I think, so it WILL try to mount when connected to a charger
13:00:22bcobcopc:0805CF04 sp:000097C4
13:00:22[7](yes, another thing for the todo list)

13:00:46bcobcobt end
13:00:59[7]with my classic build? after doing what?
13:01:17bcobcoyes with your build, happened when connecting to a usb charger in the wall
13:01:44[Saint]can confirm.
13:01:53bcobcobefore your build, rockbox behavior was to mount...
13:01:54[Saint]never used to do that.
13:02:03[Saint]well.../attempt/ to mount.
13:02:10[Saint]can't mount with no host. ;)
13:02:25[7]ok, looks like you caught a bug in the designware driver
13:02:32[7]that crash is in usb_dw_start_tx
13:02:49bcobcoits annoying when rockbox tries to mount the lighter of my car
13:03:11[7]yeah, it's the old "maxpacket is zero" bug
13:03:17[7]I think we've fixed that in emcore already
13:03:39[7]bcobco: yeah, and it's some of the things that will hopefully be fairly easy to fix
13:03:57[7]but someone needs to explain how that new framework works to me ;)
13:04:36bcobconice. please make me notice in order to test

13:20:35[Saint]Otherwise functional
13:21:00[Saint]Hang on rapid plug is reproducible, but not consistent.
13:21:17[Saint]No error printed. Just a stuck UI requiring hard reset
13:21:27[Saint]Definitely a marked improvement.
13:22:13*[Saint] tries a real Windows host
13:23:18[Saint]Seems OK. Managed to get the hang again though.

13:29:23[7]hang on rapid reconnecting is also a really old bug

16:35:49bcobcothx funman
16:36:07gevaertsThere's a fuse exfat thing somewhere
16:36:50bcobcobut that samsung exfat code is gnu
16:37:26funmansamsung or not, gpl or not, fuse or not, it doesn't make it easier to 1/ port to rockbox 2/ ignore patent issues 3/ be actually useful
16:37:55[Saint]the only thing it'd really be useful for is very large files.
16:38:24funmanI was going to suggest make filesystems loadable plugins
16:38:54funmanmaybe persistent like battery_bench
16:39:07bcobcolarge files is a good reason
16:39:13gevaertsIf we get the dynamic loader stuff, that's not too difficult
16:39:21gevaertsbcobco: rockbox is still an *audio* player
16:39:26Zagorrockbox itself has no support/use for large files
16:40:07bcobcothats true. an audio player that can play DOOM.
16:40:42Zagorwhen we add something that needs >2GB files, *then* we can discuss how to handle it
16:40:54Zagorand the most likely solution to that is "split the file"
16:41:00funmanZagor: 7.1 channels 24bits 96kHz wav files ? :)
16:41:01bcobcothe reason for large files, when you have a big storage like an ipod, i use it as an external HDD
16:43:29bcobco160GB with 4GB max filesize is something like a limitation
16:44:40Zagorit's not a bad argument, but also not so compelling as to have someone spend months adding it
16:44:59Zagorafter all, you can always partition off a couple of gigs and use whatever filesystem you want there

18:22:27saratogahardware is one and the same
18:22:48saratogathe new highspeed SDXC modes were even retroactively added to SDHC to keep the interfaces identical
18:23:27saratogamakes sense really, you don't want to have to have two controller types, one for 32GB cards (which are going to be the bulk of cards for a looong time yet) and larger

18:47:01bcobconice. the center button also connects propertly
18:47:32[7]but does it always crash if you don't press a button?
18:47:38[7]or just occasionally?
18:48:11bcobcohmm this time i tried without button and it behaves as always: mounted to usb charger (bizarre als always)
18:49:10bcobcoseems to be ocasionally
18:49:21bcobcotried again after rebooting and "mounts"
18:53:05wodz[7]: Our unwinder doesn't care if fomit-frame-pointer is used or not.

18:54:57[7]wodz ^
18:55:22wodzyes, that simply means that our unwinder can't decode more
18:55:22[7]0805CF04 is usb_dw_start_tx's call to a division function
18:55:39[7]and why can't it decode more / how do I allow it to decode more?
18:55:57bcobco1/0 = indeterminated
18:57:54wodz[7]: Our unwinder doesn't use any external debug information. It follows code path from the place where it is called and 'runs' it on virtual arm model to find patterns indicating returning from function and so on. It has some internal checks to not end up in deadloop.
18:58:27wodzfrom my experience this happens if stack is screwed
18:58:49[7]or probably because this build was compiled with a much newer gcc
18:59:13[7]so I basically need to teach it how to analyze the code right
18:59:28[7]or just look at each and every call to that function
18:59:58bcobcocan that information lines be copied to a text file in the hard disk? im worried if one of those hex numbers are not correct when i copied them
19:00:09wodz[7]: You can try increasing deadloop detection threshold in lib/unwarminder/unwarm.h but I doubt it will help
19:00:24wodzbcobco: no
19:00:35[7]wodz: I'm pondering to implement some hack to just take a full memory snapshot of that thing
19:01:04wodzbcobco: basically the system is in state where you can't trust anything to work correctly
19:01:21[7]if I can do that with the OF, I can most likely do it with rockbox as well
19:01:48[7]wodz: what's the "A" value?
19:01:53wodzarm code
19:02:02wodzT: is for thumb
19:02:04[7]i.e. that's the LR value or what?
19:02:34wodzcan't remember from the top of my head but I suppose yest
19:02:46wodzI mean I would expect to be LR
19:03:18[7]that points to an instruction after a call inside __aeabi_idiv
19:03:25bcobcoi dont know what to do to trigger that bug again. it seems to be working correctly now
19:03:37[7]so the PC value shown is further outside than the A value, which is a bit strange
19:04:34wodz[7]: That is the code I imported in rockbox
19:04:45CtcpIgnored 1 channel CTCP requests in 0 seconds at the last flood
19:04:45*[7] wonders if we should implement some generic crashkernel support

21:49:42gnutoohi, I've the sansa fuze+
21:49:53coppergood choice!
21:50:05gnutoowell, I've a hard time using its touchpad
21:50:16coppertry the touchpad sensitivity setting
21:50:35gnutooyes, how can I reset it in case I've some trouble after it's changed
21:50:40copper(and make sure you're running the latest development build)
21:50:43gnutoocan I just mount the device and change a config file
21:50:45gnutooyes, I am
21:50:59copperyes, you could do that
21:51:05gnutooso 1) is about the touchpad sensivity and zones and so on
21:51:17gnutooso I will try to change that, I know where it is in the GUI
21:51:31gnutoo2) is still about the touchpad, how do I change its key bindings?
21:51:35 Quit n1s (Quit: Ex-Chat)
21:51:41gnutooI've found a nice theme, which is the "tape" one
21:51:53gnutoobut then I'd like to mymic android's key bindings:
21:51:58gnutoopower button: on/off the screen
21:52:17gnutoowith off that locks the touchpad
21:52:32gnutooand reassigning the zones's functions of the touchpad
21:52:55gnutoo1) what does the sensivity setting do?
21:53:01gnutoodoes it change the keypress time?
21:53:01copperyou can set the display to turn off immediately when going into soft lock
21:53:16gnutooor also how big are the zone surfaces
21:53:31gnutoo2) ok good, it's in the setttings somewhere?
21:53:46copperin general -> display
21:54:19copperI seem to be mistaken
21:54:58copperipods have it
21:55:09copperbecause they have a physical hold switch, I'm guessing
21:55:50copperFYI pamaury is the resident expert on the Fuze+
21:56:13coppermaybe try to ping him when he gets online
21:56:30gnutoowell, the fuze also has the physical switch
21:56:49gnutoothere is a power button
21:56:56copperit's not a hold switch
21:56:57gnutoothe power button is also the hold switch
21:57:05gnutoowell when I press it it does the hold function
21:57:06copperyes but it's not an actual switch
21:57:11gnutooah ok
21:57:13gnutoowhat is it then?
21:57:17coppera button :)
21:57:17gnutoonot a GPIO?
21:57:21gnutooah ok
21:57:36gnutoolol, but on the software point of view it's exactly the same thing?
21:57:46copperbut I can't see why there couldn't be a setting to turn off the display when going into soft lock
21:57:57gnutooI'll look now
21:58:24copperI don't see anything in the settings
21:59:02coppertouchpad sensitivity is in general -> system

22:02:15gnutooahh, there are "scrolling" settings too
22:02:19gnutooI didn't see that
22:02:30gnutooI guess there are stuff to tweak the touchpad behaviour there
22:02:42copper"Backlight on Hold"
22:02:43gnutooI've also huge difficulties with the "left" part of the touchpad
22:02:45copperon the Classic
22:02:49gnutoosometimes it goes back
22:02:58gnutooand sometimes it does somethig totally different
22:05:45gnutoohmmm, I can't access the internal disk
22:05:54gnutooit's in usb keypad mode
22:05:58gnutooand its backlight is off
22:06:18gnutoo(I've set it accidentally to off, because I have a hard time using the touchpad)
22:06:53gnutoostill, it's funny, it can raise my volume in kde
22:07:10gnutooit could do fun stuff with usb device I guess
22:08:52gnutooit seems to export quite a lot of keys
22:09:04gnutooanyway, I wonder how I should get in an usable state again
22:10:03gnutoobInterfaceClass 8 Mass Storage
22:10:06gnutoohmmm, how to use it?
22:10:13gnutooahh ok
22:10:17gnutoocat /proc/partitions has it
22:10:23gnutooKDE didn't see it though
22:10:25gnutoolet me look
22:10:39gnutooit probably has the SD only though
22:11:22gnutooah good, it's exported
22:11:40gnutooI'll try /.rockbox/config.cfg

22:28:24gnutooSensivity seems not to fix my issue:
22:28:44gnutooit seem to only change the required touch duration
22:29:06gnutooMy issue is rather about the zones
22:29:16gnutooThe touchpad is like a +
22:29:28gnutoobut it's small
22:29:42gnutooso I often try to click on the center
22:29:49gnutoobut it interpret it as left instead
22:29:53gnutooor the reverse
22:30:10gnutooI want to click left and it ends up with the center beeing reported
22:30:39gnutooand the "back" zone doesn't do anything most of the time
22:30:53gnutooprobably because I "click" near it but not at the right place
22:36:32gnutooA good idea for usb device handling would be an iso emulation
22:36:43gnutoofor instance you select your GNU/Linux iso
22:36:48gnutooand it exports it trough mass storage
22:42:36gnutooup-down zones work well
22:42:44gnutoobut often I click on the left zone
22:42:51gnutooand it interprets it as center
22:42:59gnutooI mean I try to click

22:55:02gnutooThe battery life seem wonderfull, and I love some (new for me) rockbox features, but the input hardware of that player is awfull
22:55:11gnutooI hope that some workarround could be found somehow
22:55:29gnutooI guess that the causes are hardware and have to be worked arround in software
22:55:44gnutoolike by clever zone mappings, and good settings
