| 00:00:12 | copper | good night |
| 00:00:15 | [Saint] | ANd it is possible to remove the Apple firmware, and it will actually increase the boot time by a fairly considerable amount doing so. |
| 00:00:23 | [Saint] | I'll get you the link. One second. |
| 00:00:36 | GLC- | ok so the rockbox system/os then finds music files and arranges them to some kind of library? |
| 00:01:26 | [Saint] | Rockbox has a file borwser, and a database that uses track metadata. |
| 00:01:48 | [Saint] | http://www.rockbox.org/wiki/IpodPatcher#Advanced_Rockbox_install_methods_with_ipodpatcher <−− here is the link you would need to completely remove the Apple firmware, should you want to. |
| 00:01:49 | wodz | [Saint]: you mean decrease boot time, right? |
| 00:02:02 | [Saint] | wodz: errr, yes. I do. Whoops. |
| 00:02:41 | * | gevaerts recommends going with the standard installation method at first |
| 00:02:42 | GLC- | but wouldn't it be good to get rid of apple? i didn't bought ipod back in the day because it was Apple or ipod, it was slim sleek nice design 30GB MP3 player affordable price. so this Rockbox thing really sounds good, because i wanna sync with WMP12 |
| 00:02:42 | [Saint] | From that link, I use option: 4) OSOS contains only Rockbox |
| 00:03:15 | GLC- | standard? but it installs radio too? there is no radio.. in that model |
| 00:03:30 | GLC- | thanks for the link Saint |
| 00:03:37 | [Saint] | There is no real reason to remove the Apple firmware, ROckbox will boot by default anyway and you still have the option of booting the Apple firmware should you chose to. |
| 00:04:08 | [Saint] | But if you know you will never use the Apple firmware, there's no real point in keeping it there either I guess. |

| 00:04:34 | | Quit petur (Quit: Leaving) |
| 00:05:05 | gevaerts | GLC-: there is a radio in some accessories |
| 00:05:05 | GLC- | yeah I dunno, can I fuck up the drive? Couldn't I just reload the original firmware with iTunes? |
| 00:05:33 | GLC- | gevaerts, ah ok, good to know, those must be going cheap these days |
| 00:06:11 | gevaerts | And yes, you can always easily restore with itunes |
| 00:06:15 | [Saint] | Yes, you can always restore the device with iTunes should you want to. |
| 00:06:17 | GLC- | hmhmh maybe I'll leave the apple stuff there and decide later |
| 00:06:41 | GLC- | thanks both of you |
| 00:06:42 | [Saint] | That is a wise choice. |
| 00:06:44 | | Quit kugel (Ping timeout: 248 seconds) |
| 00:06:56 | gevaerts | That generation of ipods is really hard to break in a way that's hard to recover, unless you use the hammer™ method |
| 00:07:12 | GLC- | so with rockbox i can also use ipod sort of as giant usb stick then? |
| 00:07:30 | [Saint] | It pays to note that if you do use any accessories it would be wise to keep the original firmware and use an Application that is capable of syncing to the iTunes Database. |
| 00:07:39 | GLC- | yeah, it's the iPod video (5G) model |
| 00:08:17 | GLC- | yeah ok but there's no accessories in sight |
| 00:08:47 | GLC- | if i would of known all this Rockbox stuff 7 years ago.. :) |
| 00:09:48 | wodz | pamaury: Updated gerrit. I wonder if the same fix in rb driver will make usb failures fixed... |
| 00:09:51 | GLC- | does Rockbox increase battery life? compared to icrap? |
| 00:10:47 | pamaury | wodz: that's a good question indeed |
| 00:10:55 | GLC- | i mean does rockbox consume less energy than ipodsoft? |
| 00:11:02 | [Saint] | It can. But it can also allow you to set a terrible configuration that would hit the battery heavily. |
| 00:11:30 | [Saint] | It depends on the usage really. |
| 00:11:51 | gevaerts | It's likely going to be more or less the same |
| 00:11:51 | GLC- | ah ok, thanks, yeah I'm only going to listen music despite all the video etc, so yeah I should keep install minimum |
| 00:12:06 | GLC- | ok |
| 00:12:12 | gevaerts | apple does a fairly good job at battery usage in their firmware usually |
| 00:12:31 | GLC- | hmm, ok |
| 00:12:51 | [Saint] | They are definitely a lot better at video on this device than Rockbox is. |
| 00:13:03 | gevaerts | Don't compare to what you remember from seven years ago though, the battery isn't going to be as good any more :) |
| 00:13:06 | GLC- | but yey! now I can sync with WMP12 how fantastic is this?!!!1 thank you guys |
| 00:13:15 | | Quit krnlyng (Remote host closed the connection) |
| 00:13:55 | GLC- | true, but it's not half life yet either |
| 00:14:17 | [Saint] | Album art should "Just Work" if you sync with WMP as well, which is a bonus I guess. |
| 00:14:43 | GLC- | yeah, only music and perhaps an occasional ebook if I go away for awhile, like vacation etc |
| 00:15:00 | GLC- | great! yeah album art is a must have |
| 00:15:05 | [Saint] | I do recommend reading through our fine manual: http://download.rockbox.org/daily/manual/rockbox-ipodvideo/rockbox-build.html |
| 00:15:44 | GLC- | thanks, I'll read the links before plugging the pod |
| 00:15:52 | GLC- | thanks for the link |
| 00:16:14 | pamaury | damn, the freescale nand code is uber-complicated |
| 00:16:34 | pamaury | i'm trying to reverse the FTL but I'm still far from done with the pure nand layer yet |
| 00:17:12 | GLC- | yeah, I have plenty to do before i get to conf my ipod, in a few days, I'll report here how it goes, my first imressions etc (not that I think anynone's interested but i like to think loud) |
| 00:17:41 | [Saint] | Installation is really a very straightforward process. |
| 00:18:05 | [Saint] | ANd it is pretty much impossible to hurt the iPod in an irrecoverable way. |
| 00:18:45 | GLC- | yes I saw some screenshots of the installer, looked easy, I'm not novice on PC |
| 00:18:45 | wodz | pamaury: In case of bulk ep this should be the same, if so how it was ever even half-working. I suspect lots of multi 512b transfers are used. |
| 00:18:49 | [Saint] | Installation literally involves clicking a few buttons and waiting about a minute, depending on your internet connection. |
| 00:19:06 | GLC- | ok |
| 00:19:27 | GLC- | and hey it's goof to know that the pod cannot brake down, yey! :) |
| 00:19:59 | GLC- | *good |
| 00:20:21 | [Saint] | It certainly is possible to do some damage with our tools, but you would need to be trying *really* hard to do so - it would need to be a deliberate effort. |
| 00:20:55 | pamaury | wodz: indeed, luck maybe ^^ |
| 00:21:10 | [Saint] | Using things as intended is pretty much bullet proof though. |
| 00:21:11 | pamaury | rockbox doesn't use many blocking transfers |
| 00:22:30 | GLC- | ok, yeah, just click few buttons on the installer, shouldn't be that difficult |
| 00:23:04 | GLC- | oh hey it has a lot of music in it so I guess I'll have to format it before rockboxing? |
| 00:23:30 | GLC- | it's probably in the manual :) |
| 00:25:00 | [Saint] | If you have the music backed up elsewhere, it is probably best to do a restore with iTunes just before you install Rockbox. |
| 00:25:18 | [Saint] | You can format it manually, but iTunes is absolutely guaranteed to get it right. |
| 00:26:22 | [Saint] | The other option is mounting the device in disk mode, enabling "show hidden files", and just deleting everything on the disk. |
| 00:26:37 | [Saint] | Formatting the disk is a bit harsh. |

| 09:49:11 | wodz | [Saint]: Maybe you could make battery_bench on n2g to check if we have regression there as well? According to [7] n2g can measure current draw using internal adc so this would allow to fast(er) pinpoint offending commit |

| 10:04:59 | copper | but I'm not going to bisect a year's worth of commits |

| 10:05:33 | copper | it's not that |
| 10:05:48 | copper | I figure you guys are a lot more likely to be able to make educated guesses |
| 10:06:26 | GodEater | you'd be amazed at the number of regressions which defy educated guesses |
| 10:09:03 | GodEater | it's not the bisecting that'll take the time though in this case, it's having to run a battery bench with each build |
| 10:09:14 | copper | that too |
| 10:09:29 | GodEater | which, since you're the one with the issue - you're going to have to do anyway |
| 10:09:38 | GodEater | so you might as well make a start on the bisecting :) |
| 10:09:40 | copper | what? |
| 10:09:44 | copper | "I'm the one"? |
| 10:10:33 | copper | I highly doubt this is a freak occurence that only affects me |
| 10:10:40 | GodEater | unless I've missed the hordes of other people reporting it? |
| 10:11:28 | copper | a difference between 30 hours and 25 hours might not be obvious when using the iPod normally, for listening to music |
| 10:11:56 | copper | and the difference could easily be attributed to an aging battery |
| 10:12:26 | copper | and, few people ever take the time to report bugs and run battery benchmarks |
| 10:13:05 | wodz | copper: Do you have battery_bench of old build made currently to exclude battery aging & co ? |
| 10:13:25 | copper | I'm sorry, I don't know what you mean |

| 11:56:05 | pamaury | DuperMan: you have two ways: |
| 11:56:05 | pamaury | 1) compile with an additional define: "make ENABLEDPLUGINS=yes" |
| 11:56:31 | pamaury | 2) enable plugins in configure: in tools/configure, find the "creativezen)" section and change plugins="" to plugins="yes" |
| 11:58:19 | DuperMan | tried, failed. it built like 2 or 3 plugins. can't go deeply into it but thanks, I'll be back in the evening (I hope) |
| 12:00 |
| 12:00:05 | pamaury | I suggest 2) so you don't have to remember the magic define all the time |

| 20:08:49 | pamaury | The NWZ have very poor battery life, so I wanted to make sure if it was related to some power regression or it was nwz specific |
| 20:09:02 | copper | isn't it a bit much of a coincidence that both the Fuze+ and the Classic have regressed? |
| 20:09:19 | copper | someone should run a benchmark of another target |
| 20:09:22 | copper | hmmm |
| 20:09:48 | copper | I could run a battery benchmark for the Clip+, but I don't have a previous reference |
| 20:09:48 | pamaury | I don't know, on the fuze+ that's not that surprising given the number of changes in the past month |
| 20:10:01 | pamaury | I was excepting some regressions when adding support for the stmp3700 and stmp3600 |

| 20:12:29 | Narod | Do they, though? Would love to battery bench my two NWZs. :) |
| 20:13:34 | pamaury | battery life on the nwz is very low at the moment: ~10hours |
| 20:13:35 | copper | to put it in other words: did anyone here commit something pertaining to CPU usage? |
| 20:13:52 | copper | or boosting or powersaving or whatever |
| 20:14:20 | Narod | Wow, okay. I never really used it for that long in one go. |
| 20:14:24 | copper | anything that could remotely have an effect on battery usage |
| 20:14:36 | pamaury | I don't know, I try to follow on the commits but I don't remember anything special |
| 20:14:43 | pamaury | and it might be something less obvious |
| 20:15:20 | copper | ok, this is what I'm going to do: I'm going to run battery benchmarks on the Clip+, with a year old revision, and the latest revision |
| 20:15:35 | copper | if I see a significant difference, then it's probably something target-agnostic |
| 20:16:10 | copper | I don't mind running battery benchmarks on the Clip+, because I never use it |
| 20:17:09 | pamaury | the only thing which could be remotely be related is some change in the eq I think, but I think it's not enabled by default so it should not changed anything |
| 20:18:52 | copper | well, if I don't see a significant difference with the Clip+, then at least I can rule out a target-agnostic commit |
| 20:19:08 | copper | I'll test the same revision as the iPod Classic |
| 20:19:30 | pamaury | on imx233 I see plenty of reasons why battery life could be worse than it used to be ^^ |
| 20:19:39 | copper | it should help narrow it down, I think |
| 20:20:01 | copper | because the regression is definitely real |
| 20:20:47 | copper | I'm hoping the Clip+ benchmark will show the difference, because in that case, I can run as many benchmarks as I need, on the Clip+ |
| 20:21:21 | pamaury | when my bench is done I will start two more benches on my two fuze+ for other revisisons |
| 20:21:32 | pamaury | currently the two revisions I chose were imx233 related |
| 20:22:34 | copper | I will use FLAC as the codec, in order to match my iPod Classic benchmarking conditions |
| 20:22:47 | copper | and because FLAC decoding is very fast |

| 22:42:50 | pamaury | wodz: I hope I don't say something stupid here but ZLP doesn't apply the same to bulk |
| 22:43:06 | pamaury | for bulk transfers you send a ZLP only to prematuraly terminate a transfer |
| 22:43:30 | pamaury | if you are requested for 512 bytes, you must send 512 and no ZLP because that's the exact amount requested |
| 22:43:36 | wodz | pamaury: Hmm, it seems to work. I copied ~140MB file and spammed ep0 during copy with lsusb -vv in loop. The transfer survived and files are the same according to md5sum |
| 22:44:02 | wodz | I spammed ep0 during md5summing also |
| 22:46:09 | pamaury | what I don't understand is why it was failing |
| 22:47:16 | pamaury | because this zlp fix only apply to control transfers and most if not all transfers you send when spamming are not multiple of 64 in length, so no ZLP applies |
| 22:47:22 | pamaury | anyway, if it works, that's great :) |

| 23:26:11 | pamaury | wodz: this is getting interesting |
| 23:28:06 | pamaury | I wonder if it could be somehow related to back-to-back setup packets |
| 23:28:43 | wodz | yeah, rb driver with ZLP fix survives a few rounds of spamming while OF gets nuked by the first few spamming lsusbs |
| 23:29:13 | [Saint] | Hmmmm - clearing backdrops is definitely rather fucked up in ROckbox. |
| 23:29:25 | [Saint] | Not even changing themes works consistently. |
| 23:29:36 | [Saint] | Reboot after the fact does, though. |
| 23:30:48 | wodz | pamaury: spamming with lsusb while there is no transfer does not harm btw. |
| 23:33:53 | pamaury | I'm beginning to wonder if this is really a software bug... |
| 23:34:53 | wodz | me too |
| 23:36:24 | wodz | I'll post zlp thing to gerrit and ask mortalis to see if it helps |
