00:00 < user890104> and the display is stuck at the main menu, which doesn't respond
00:01 < user890104> it's simple to reproduce it: replug the usb cable like 10 times for 5 seconds, and you're done
00:05 < user890104> after resetting, i entered rockbox by holding the center button in the emcore menu
00:05 < user890104> i kept holding it, but the ipod entered usb mode
00:06 < user890104> and it surprisignly mounted
00:06 < TheSeven> might be a race condition that's a lot harder to reproduce on nano2g because of its much lower storage response times
00:06 < TheSeven> can you send me that build? (the zip ideally)
00:06 < user890104> and the .elf?
00:06 < TheSeven> for now i just want to reproduce it
00:07 < TheSeven> but having the right elf for that build can't hurt
00:08 < user890104> http://www.datafilehost.com/download-efad97db.html
00:10 < user890104> http://www.datafilehost.com/download-2e49bc36.html <- same build, with the .elf included, you can delete the previous one if you already downlaoded it
00:10 < TheSeven> bugger
00:10 < TheSeven> never managed to reproduce that bug before, and now, while trying to install your build, it refuses to mount :/
00:11 < TheSeven> exactly the same behavior
00:12 < user890104> welcome to the world of screwed ipod classic users who can't mount their ipods :)
00:12 < TheSeven> i'm currently running r30904:30906M
00:14 < user890104> would a usb packet dump help solving anything? i can do that on windows
00:14 < user890104> i don't see other way of being able to see what's happening
00:15 < user890104> maybe uart+debugf
00:16 < TheSeven> well, at the first glance it looks like usb connection during boot screws something
00:17 < TheSeven> hm, managed to get it into a state where it won't recognize usb connection at all
00:18 < TheSeven> well, it does wake the backlight, but it doesn't enter usb mode
00:19 < user890104> does it spin up the hard disk?
00:20 < user890104> mine doesn't in this condition
00:20 < TheSeven> this smells like some highlevel race condition
00:20 < TheSeven> heavy usb plugging/unplugging action has never really worked right
00:22 < user890104> it works on n2g with the 3_10 branch
00:22 < TheSeven> that's flash though
00:22 < TheSeven> so reloading the skin etc. after unplugging works almost instantly, unlike on the classic
00:23 < TheSeven> if we hit it in the middle of that on the classic, things will go awry
00:23 < user890104> ok, i seem to have locked it up completely
00:24 < user890104> but using an usb extension cable so i can reconnect it even quicker
00:24 < user890104> by*
00:24 < user890104> backlight on, stays on the usb screen
00:24 < user890104> hdd is on
00:25 < user890104> and the clock doesn't change
00:26 < user890104> isn't rockbox using something enter_critical_state or something like that (like in emcore) for such actions that can't be interrupted?
00:27 < TheSeven> these actions are way too complex and time consuming
00:30 < TheSeven> critical sections in emcore terms are usually sub-microsecond operations that can't do any blocking i/o
00:31 < TheSeven> hm, now i got one of those "doesn't mount" cases again
00:34 < TheSeven> wtf
00:34 < TheSeven> just had a boot attempt where emcore failed to turn the backlight on
00:35 < TheSeven> this device is mysterious...
00:39 < TheSeven> this is definitely a rockbox bug
00:40 < TheSeven> with older releases this works absolutely flawlessly
00:50  * user890104 goes to sleep
00:50 < user890104> here is the emcore build i'm using, just in case: http://www.datafilehost.com/download-4f9c4af9.html
00:51 < user890104> it includes the same rockbox build, i was too lazy to remove it from the archive
01:32 < TheSeven> r30000 => "No partition found. Insert USB cable and fix it."
01:37 < TheSeven> r29000 => "ATA error: -11 Press ON to debug"
01:37 < TheSeven> wtf is going on with that target
02:01 < TheSeven> something apparently broke between r29640 and r30000
02:17 < TheSeven> r29690 and r29700 to be more precise
02:28 < TheSeven> damn, the behavior is basically random
02:28  * TheSeven gives up for tonight

10:16 < NiketoNabu> Hithere! Can i ask about some troubles of RockBox? I have freeze the ipod, when i try to setup the sound settings while the track is playing. freeze canceled only rebooting by menu+select 
10:29 -!- liar [~liar@clnet-p09-185.ikbnet.co.at] has quit [Read error: Connection timed out]
10:57 < user890104> NiketoNabu: this is a known issue
10:57 < user890104> the ipod freezes in random places
11:14 < NiketoNabu> and what can we do?
11:14 < NiketoNabu> nothing?
11:17 < user890104> unless you find what is causing the problem and know how to write code in C and ASM, nothing
11:18 < user890104> this is why the port is marked as Unusable on rockbox.org
11:18 < NiketoNabu> by the way - my pod freezes only in this case
11:24 < NiketoNabu> user890104, is the any hope that this port get status @stable@ some day?)))
11:46 < [7]> NiketoNabu: so you say that it freezes *reproducibly* when doing that?
11:47 < [7]> and it won't be stable any time soon. if we're lucky and find the bugs, maybe in like half a year. if we don't find them, maybe never...
11:48 < NiketoNabu> yes - reproducibly: if pod is freezing it freezes only in this case
11:49 < NiketoNabu> after 1 day using device
11:49 < NiketoNabu> beta testing))))
11:50 < NiketoNabu> in other cases it fulli stable on my opinion
11:51 < NiketoNabu> i shoud tets it bit longer
12:01 < [7]> NiketoNabu: reproducibly means that it freezes *always* when you try to do that
12:01 < [7]> i.e. if you do the same thing again, it will always freeze again, or at least in the majority of cases
12:02 < [7]> if this is true, it might put us a big step forward in locating the root cause of this problem
12:02 < [7]> if it isn't, it was probably just one of those random crashes that occur every couple of hours
12:04 < NiketoNabu> not always, but very often and only in this case - reproducibly?
12:04 < [7]> so if you want to make it crash, what exactly would you do? (so that I can try the same on mine)
12:04 < NiketoNabu> very often - 1 freeze on 3 attempts
12:05 < NiketoNabu>  rough
12:05 < [7]> that's what I'd call semi-reproducibly... and that would definitely point to something I2C-related
12:06 < [7]> so you just try to change the volume or similar settings while it's playing music?
12:07 < NiketoNabu> i try to put bass or terible level or use the EQ in most cases
12:07 < NiketoNabu> the most usefull options to me
12:07 < [7]> what kind of music files? mp3? mp4/aac? wma? something else?
12:07 < NiketoNabu> when the track is playing
12:08 < NiketoNabu> if not playing - i have not freezez
12:08 < NiketoNabu> mp3 but not shure - i have a flac too
12:08 < [7]> hmm, bass/treble is done by just sending the values to the audio chip, while the eq is calculated in software on the audio data that's sent to the chip... but both of these are affected?
12:09 < NiketoNabu> volume - no - volume is allright
12:09 < NiketoNabu> only if i get into @settings@ tab
12:10 < NiketoNabu> yes - both
12:11 < NiketoNabu> i have to get more statistic to say you precisely
12:12 < NiketoNabu> but this three options offer freezez when tracks are playing
