00:05:30gevaertsOr rather, code that uses floating point numbers :) See http://en.wikipedia.org/wiki/Floating_point
00:05:44Roronoait might be because i have not gone through the code of 2008 GSoC
00:05:59AlexPgevaerts: Yes, I was trying to avoid explaining it by saying the same thing again :)
00:06:20gevaertsAlexP: well yes, but fixed point numbers are also not necessarily integer numbers
00:06:30AlexPRoronoa: floating point/integer is a pretty basic thing common to pretty much everything
00:06:36AlexPgevaerts: true

00:07:26Roronoabut just i thought that it might be some thing in Audio Codec Theory
00:07:45gevaertsThe point is that most rockbox targets have no hardware support for floating point operations (FPU), so fixed point is much more efficient
00:08:05gevaertsno, it's the same floating point as everywhere else
00:08:19 Quit Schmogel (Quit: Miranda IM! Smaller, Faster, Easier. http://miranda-im.org)
00:08:59Roronoaso, one of the parts of the project is to remove the use of floating point numbers
00:09:35gevaertsas I understand it, yes. (I'm not a codec expert...)
00:09:43AlexPAnd yes, me saying integer was also bad (lazy :))

00:10:42Roronoai need some link from where i can get information on 'Audio Codec Theory' as i know almost every thing else specified
00:10:43soaptorne - I thought the "fear" over the remaining patch in FS #9708 was that unboosted buffering might cause system lag. I know Soap_Hotel misspoke when he ;) called it "DMA changes".
00:10:55bieberSo on targets without an FPU, is the compiler doing floating point ops by generating normal arithmetic code to do it?
00:11:07 Quit pamaury (Quit: Quitte)
00:16:51gevaertsb0hoon: if the code uses floating point, yes. It's slow though, and therefore to be avoided, especially in codecs. (Last answer of the day. It's bedtime)

00:43:03I3uckwheati have a quick question
00:43:12saratogastripwax: do you have any theory why the new mdct lib doesn't seem to perform much better in libtremor then the old code?
00:43:25saratogaeven on arm9 the performance increase seems minimal

00:45:24 Quit planetbeing (Quit: planetbeing)
00:45:34saratogafor instance, doom on the PC used fixed point math so it could run on PCs without an i387 unit
00:45:44Unhelpfulbresenham's predates *common* FP hardware, doesn't it? also the related circle algo?
00:45:47saratogastripwax: yeah but someone else on the tremor list benchmarked it and saw no real benefit
00:45:52stripwaxi.e. that those processors perform better on gcc code, and that the optimisations are mostly loop unrolling / avoidance of branches / ldm / stm
00:46:02I3uckwheatwow they need to go quite a way before sansa fuze v2 comes out
00:46:21stripwaxif they could benchmark on arm7tdmi they hopefully ought to see a bigger improvement
00:46:31saratogastripwax: funman's ARM9 results weren't very impressive either
00:46:46saratogathe improvement was marginal, whereas in rockbox arm9 got significantly faster
00:46:49stripwaxmy other guess would be that the complexity of the indexing offsets the reduced number of multiplies especially on cores where multiplication requires fewer cycles than arm7tdmi
00:46:51 Quit I3uckwheat (Client Quit)
00:46:57stripwaxwhich targets are arm9?
00:46:57saratogaunless our ASM version of the old MDCT is actually slower on arm9 :)
00:47:09stripwaxdoes the libtremor patch include icode/idata usage?
00:47:15stripwaxit may well be
00:47:19saratogastripwax: AMS, Nano2G, Gigabeat F
00:47:42saratogastripwax: it doesn't, but afaik, no one has tested on hardware with IRAM anyway
00:47:49stripwaxi thought improvement was minimal on nano2g. for vorbis anyway. big improvement for wma. i might be misremembering though.
00:47:52saratogaof our arm9 targets, only the nano2G has fast IRAM
00:48:20saratogawell we're comparing against the ASM optimized old mdct in rockbox, whereas libtremor uses a dumb c version
00:48:29saratogaat least on PP the speed up for ASM was fairly large
00:48:36Unhelpfulsaratoga: arm9tdmi is *mostly* arm7tdmi in terms of execution times. i think the major change is 1-cycle (with delayed result) loads, and that loads can retire out-of-order at all. arm7tdmi loads are 3 cycles. more if they block on RAM.
00:48:52 Join moos [0] (moos@rockbox/staff/moos)
00:49:07Unhelpfulldm/stm timing changes a bit too... would have to check ASDG for details
00:50:54saratogause the load/store improvement is much smaller on arm9
00:50:54saratoga"yes"
00:50:54stripwaxif the dumb c mdct is faster on arm9 than either the old asm mdct or the new asm mdct then we should use the dumb c, really.
00:50:54 Join Adubb [0] (~aldubuc@67.201.160.144)
00:50:54saratogai guess i need to port the old mdct's asm to libtremor and see if its faster
00:51:56stripwaxquite why the improvement was so big on nano2g for wma, I simply don't know. caching maybe. no idea.
00:51:56Unhelpfulsaratoga: well, on arm9tdmi you can actually benefit from trying to load constants early, though. arm7 loads don't retire early. pretty much nothing does, to my knowledge, on arm7.
00:53:20stripwaxalso, for all i know, my hand-coded arm asm is *terrible* for pipelining on anything other than arm7tdmi .
00:54:30stripwaxthe mag/ang stuff might perform worse on targets that have good branch prediction.
00:54:44Unhelpfulsaratoga: yeah, arm9tdmi ldm is 1c/reg, 1c extra delay for availability of last register loaded, 1c extra delay for using ldm on 1 register
00:55:08stripwaxsaratoga - let me know if you want any more ideas of why performance improvement might not have been as great as expected! :-)
00:55:18Unhelpfulldr is 1c, result not available for 2c more
00:55:27Unhelpfulso difference is mainly codesize

01:15:45stripwaxon non-arm7tdmi, you could get better performance by interleaving loads and calculations, as opposed to doing a single ldm load followed by calculations that depend on the loaded registers.

02:02:33stripwaxbasically the configure file matches uname against arm-*-* which just doesn't work.
02:03:03stripwaxbut I see that same problem is still there in the trunk. sigh. Maybe the nslu2 guys fixed it in their libvorbisidec package, only, without upstreaming it.

02:28:35xoochHi, I'm a student and have been looking at the rockbox gSoC projects for this year, and although a few of the projects look good, I'm quite interested in improving video playback
02:29:28linuxstbxooch: Great! No need to wait until the summer though, you can get involved with Rockbox now...
02:30:41xoochI'm more than happy to, I just need to talk to people about the project more in depth, or places to get started
02:30:57JdGordonwell you've come tot he right place :)
02:31:03saratoga_labsure, which part looked interesting?
02:32:05xoochit was mainly trying to getting more video codecs working and integrating them into core playback
02:32:49linuxstbWhich codecs?
02:33:55 Quit planetbeing_ (Quit: planetbeing_)
02:35:06xoochon the site it mentions integrating mpeg4 and aac into normal playback, but getting new codecs to run such as maybe xvid would be good (although I don't know how difficult this would be)
02:35:33saratoga_labwell xvid is mpeg4 :)
02:35:46xoochah
02:36:15saratoga_labwell its an implementation of parts of the MPEG4 spec
02:36:32saratoga_labbut you should probably define what you want to decode, not what encoder you will use to encode it
02:36:42saratoga_labxvid can actually produce all sorts of different types of mpeg4 video

02:47:08saratoga_labwhen i applied to port the wma decoder, I started by looking at the code and making a good argument in my application that the project should be feasible based on the work to be done
02:47:37 Quit Strife89 (Quit: Night.)
02:47:54xoochok, i'll start having a look through that now
02:48:32saratoga_labdiscussing things before hand on IRC also probably helps you come up with good ideas
02:54:36xoochsince i haven't done any coding involving video, would a different project be more suitable or do you think this would be ok?
02:55:22saratoga_labyou don't have to have done something like this before
02:55:35saratoga_labbut you do have to convince us that you're likely to finish the project :)
02:55:46xoochok
02:56:09saratoga_labare any other ones interesting to you?
02:56:25saratoga_labkeep in mind you can propose other projects not on the official list, though i suggest talking those over with us first

02:59:50saratoga_labBlue_Dude: what about you, any interest in helping out with GSOC this year?
03:00
03:00:19Blue_DudeUm, maybe. My schedule is month to month. No way of knowing if/when I'll have time to commit to it.
03:00:59Blue_DudeI'm not really a pro developer. I just implement cool stuff I happen to want. :)
03:01:23saratoga_labhaha
03:01:25saratoga_labsame here
03:02:17Blue_DudeThat makes it fun instead of work.
03:02:57saratoga_labmentoring is mostly done over email or gtalk, so you may want to keep an eye on things and maybe be a backup mentor if someone does a project in your area
03:04:00Blue_DudeOK. I can probably assist with DSP stuff since I spent most of my time there. I'll keep an eye out.
03:04:09Roronoasaratoga: I would like to discuss with you the project New WMA audio codec which i left off yesterday before sleep
03:04:31saratoga_labsure go ahead, i'm doing lab work but i can reply
03:06:25 Quit robin0800 (Remote host closed the connection)
03:06:29Roronoabasically i would like to know where do i start reading for Audio Codec Theory
03:06:52Roronoahow much am i supposed to know before starting the project
03:07:21saratoga_labwell i knew next to nothing about it aside from some generic DSP stuff when I applied for the original wma project
03:07:31saratoga_labi would hope you have a basic idea of what an FFT does
03:07:39Roronoaas far as the coding goes i know C and have worked on assembly in x86 and PIC's DSP
03:08:12saratoga_labthats mostly what you'll need
03:08:27saratoga_labporting a codec doesn't have to involve understanding how it works, although it may be easier if you do
03:11:26Roronoais Assembly of ARM quite diff from what i have done earlier or is it nearly the same
03:11:49saratoga_labi haven't done any x86 or PIC, but arm isn't too bad in general
03:12:03saratoga_labits very compact RISC with 16 registers
03:12:18Blue_DudeRoronoa: the Rockbox codec API is pretty straightforward. You could start with a shell codec that has placeholder components and fill in the blanks as you develop the decoding engine. You probably won't have to do much if any assembly code.
03:12:21saratoga_labvaguely like MIPS if you've done that, although somewhat less readable
03:14:29saratoga_labRoronoa: are you familiar with the fourier family of transforms?
03:14:39RoronoaRISC with 16 registers seems similar i think i may be able to do it
03:14:41Roronoano
03:14:50saratoga_labnot at all?
03:15:11RoronoaI mean i have done in Mathematics not implement it
03:15:29saratoga_labah ok
03:15:33Roronoawe had fourier transform of complex functions
03:15:50saratoga_lablet me put it this way, if I asked you the difference between a fourier transform and an FFT could you tell me ?

03:16:25saratoga_labok thats fine
03:16:44Roronoashall i look into that
03:16:46saratoga_labif you've done them on paper you can pick up the rest in practice, but learning the calculus from scratch would have been hard
03:17:28saratoga_lababout codecs, the wikipedia page on JPEG compression actually lays out the general theory that all lossy codecs use, although the DCT in that codec will be replaced with the closely related MDCT in WMA Pro
03:17:34***Saving seen data "./dancer.seen"
03:18:53Roronoaok i will look into that
03:20:34saratoga_labbut the basic idea is to transform to some domain where useless detail can be extracted, and then just compress the remainder using something like huffman coding or whatever lossless strategy you want
03:21:12saratoga_labfor video, a DCT is used, for audio, an MDCT is used
03:22:54Roronoaok. i currently don't know much about that but i will look into it and tell you soon (may be by today)
03:23:03saratoga_labi described wma decoding a little bit here, pro is very similar: http://en.wikipedia.org/wiki/WMA_Pro#Windows_Media_Audio
03:23:11saratoga_labok sure
03:23:19saratoga_labdon't mean to pile on information mid semester
03:24:16Roronoano it is not a problem
03:26:35Roronoathese days mostly i am involved in microcontroller coding on MSP430 but i think i can take out some time till the application date for GSoC the rest i will start when my vacations start by april end

10:05:35Zagorwodz: it only does that if the hold switch is engaged
10:06:00Zagorand if it can't detect the original firmware
10:07:20TheSevenwe have that on nano2g for the "FTL borked" case, too
10:07:32ZagorI would call those error screens rather than boot menus
10:08:32wodzWhats wrong with boot menus? Just add timeout and there is not problem at all
10:09:14wodzalmost all 'linux' bootloaders I am aware of do this that way
10:09:20TheSevenprobably as always: some added complexity, more possible problems and a bit more boot time
10:09:26*S_a_i_n_t agrees with this...but never wanted to be the one to open this can of worms in IRC
10:09:35ZagorS_a_i_n_t: :-)
10:09:37JdGordonthe boot menus people are asking for are to let you choose which OS to boot into, i.e ipodlinux, OF, us
10:09:55TheSevenS_a_i_n_t: we've already opened that can several times, and so far, all the worms have always hopped back into the can in the end :-P
10:10:18S_a_i_n_tyes, I've seen worms fleeing this channel :P
10:11:10JdGordonthe support "reason" against any sort of button fiddling is just nonesense
10:11:42S_a_i_n_tI can't remember who, but someone mentioned earlier there being a physical, and an unwitten no-do list...
10:11:50*S_a_i_n_t demands to see the unwritten one :P
10:12:36TheSevenwell, judging from the recent mailing list traffic, those will need to be written, too, or they'll just be killed
10:14:22TheSevenand yes, fancy bootloaders would definitely cause some additional support traffic, but we could just make them unsupported (as they currently are), maybe besides some FAQ list
10:14:34JdGordonthe problem is there really isnt such a listing, it entirely depends on who is around to complain (change is bad remember? )
10:15:18TheSeventhere's http://www.rockbox.org/wiki/NoDo
10:15:24TheSevenbut yes, that's way incomplete
10:15:29linuxstbTheSeven: I can't see how they would cause *more* support traffic. Almost every day someone asks "how can I boot the original firmware?"
10:16:09scorche|shZagor: do you have any clue why the wiki doesnt show certain column separations in tables as seen on the DevCon2010 wiki page?...the WYSIWYG page and the preview both show the separations...
10:16:30TheSevenwell, yes, if a fancy bootloader based on the current rockbox bootloader framework would probably not cause much support issues, but something like iloader will
10:16:43Zagorscorche|sh: which separations?
10:17:13TheSevenand in the end, one of the reasons for this is to get rid of those annoying FTL screwups, which will force us to use nor-based bootloaders, which are likely to cause additional trouble
10:17:44scorche|shZagor: at the moment i see no separation between any of the first 2 columns on http://www.rockbox.org/wiki/DevCon2010
10:17:54JdGordonTheSeven: what I'd suggest is offering 2 bootloaders for those targets, it's not like it would add much extra work once the initial gui is done

10:18:44Zagormy iceweasel 3.5.8 shows them fine
10:18:46TheSevenscorche|sh: my FF3.6 (windows) shows them
10:18:47Zagorstrange
10:19:33JdGordonff 3.5.8 here looks fine also
10:19:47*scorche|sh updates firefox from 3.5.7 (windows)
10:20:44TheSevenJdGordon: basically there are 4 combinations that we could have:
10:20:45TheSeven- NAND-based trivial bootloader (the current RB bootloader)
10:20:47TheSeven- NAND-based fancy bootloader (the old iLoader, deprecated)
10:20:48TheSeven- NOR-based trivial bootloader (not implemented yet, and not much point in it)
10:20:50TheSeven- NOR-based fancy bootloader (the current iLoader)
10:21:30TheSevenhaving them NOR-based allows to get rid of those FTL problems, why it doesn't neccessarily mean that the bootloader needs to be fancy
10:21:37JdGordonok, but in general, there is no real reason why we couldnt have a fancy and boring bootloader for each target
10:21:55TheSevenon the other hand, NOR-based bootloaders are likely to cause installation trouble, depending on the exact way of installation and NOR backup creation
10:22:18linuxstbTheSeven: Why is there not much point in a NOR-based trivial bootloader?
10:22:23 Join xsteadfastx [0] (~spectrum@91.186.35.111)
10:22:59TheSevenone point why fancy bootloaders is opening a can of worms, is that people will ask for more and more questions, themeability etc. (roughly like what iLoader can do now)
10:23:57TheSevenlinuxstb: because the existing fancy one is working just fine, and can simulate the trivial one's behavior with no noticable boot time overhead
10:24:25TheSevenbut yes, we could try to port the rockbox bootloader to NOR
10:24:33JdGordonTheSeven: only stupid people want themeability in the bootloader! so let them do it on their own
10:25:26S_a_i_n_t<feels stupid>s wants his bootloader to look pretty too! <.feels stupid>
10:25:32linuxstbTheSeven: That's not a reason IMO - a NOR bootloader of some kind still needs to be implemented in Rockbox.
10:25:34JdGordonso you shold!
10:25:42JdGordon(feel stupid that is)
10:25:46S_a_i_n_t:P
10:25:58TheSevenpeople will always like if their bootloader look and feel matches their rockbox theme
10:26:06TheSevenand it isn't hard to implement either
10:26:18S_a_i_n_t*that* what I should have said...
10:26:45linuxstbTheSeven: But I'm not strongly against a boot menu either, but given the time that Rockbox boots, maybe implementing a new "boot screen" in Rockbox would be a better way to do it. That way, you get full theming, the existing UI widgets, even a voice UI...
10:27:17TheSevenyou mean a boot menu plugin run through autorock? :-P
10:27:38S_a_i_n_tbut it would take longer to boot....say those that desire no fancy boot options.
10:27:39linuxstbMaybe, yes. And users can set their "start screen" to that if they want.
10:27:48S_a_i_n_tIs *that* why its "no-do"?
10:28:16TheSevenS_a_i_n_t: rockbox would boot equally fast, because it would just need to terminate the boot menu if you choose it
10:28:28JdGordonlinuxstb: can we rolo the OF on any targets?
10:28:31TheSevenhowever, all other firmware would boot like 3-5 seconds slowe
10:28:46TheSevenJdGordon: we can rolo about everything on nano2g
10:28:49ZagorS_a_i_n_t: it's not a nodo just because nobody wants to do it
10:29:23TheSevenwhat would really bug me with that rolo approach is that it will sit there for several seconds to do an FTL sync
10:29:25linuxstbJdGordon: If not, we would need to try to implement it... I've always thought a "start OF" option in the main Rockbox menu would be nice.
10:30:21 Quit kunal (Ping timeout: 260 seconds)
10:30:44TheSevenhm, we can rolo things like ibugger, but neither the OF nor disk mode right now, because we trash the sysconfig during boot
10:30:52TheSevenso we would either need to keep or recreate it
10:31:23TheSeventhat wouldn't be hard of course, but it would mean even more target-specific code in rolo
10:31:45JdGordonrolo SHOULD be target specific thoguh?
10:32:08TheSevenprocessor-specific, rather
10:32:26 Join will__ [0] (~chatzilla@adsl-76-235-40-183.dsl.dytnoh.sbcglobal.net)
10:33:09linuxstbTheSeven: The sysconfig stuff should be saved for older ipods as well - so it's target specific, not processor.
10:33:23TheSevendo they even do it the same way on the older ones?
10:35:00linuxstbI don't know how the Nano2G works, but the NOR bootloaders on older ipods store a sysconfig struct at the end of IRAM.
10:35:47will__I accidentally created an "Active Undelete" (it's a commerical program) recovery USB device out of my e250v1. I haven't shut it off yet, but I'm pretty sure the partition table and MBR got messed up. Since it is still booted, is there an easy way to fix this?
10:35:53TheSevenon nano2g, it's just a pointer at the end of IRAM and the sysconfig struct is somewhere in the IBSS of norboot, so it could be overwritten by our IRAM copying code
10:36:52linuxstbI can't remember the details on the older ipods, but I would be surprised if Apple changed it. But yes, it needs saving by (probably) the crt0.S code for the bootloader.
10:36:58TheSevenso i'd vote for re-creating it during rolo
10:37:07linuxstbYes, or recreating...
10:37:35TheSeventhe code for that is already in iloader, to be able to boot the OF, so that would be a matter of copy'n'paste
10:37:55linuxstbHow much code is that? Wouldnt' it be simpler to just save/restore?
10:38:01will__gevaerts
10:38:15TheSevenlinuxstb: around 50 lines
10:38:25TheSevenso yes, save and restore might be easier
10:39:23linuxstbAlthough that would mean people would have to update their bootloaders.... So maybe recreating it in Rockbox would be a better way to do it.
10:39:36linuxstbOr do you save any parts of it?
10:40:40TheSeventhe current rockbox bootloader will trash it, iloader will re-create it at the end of iram (immediately before the pointer to it)
10:41:45linuxstbYes, what I meant was whether iloader requires any of the original values when recreating it? I've forgotten what it actually contains.
10:42:08gevaertswill__: I think the easiest way to fix it will be using either recovery or manufacturer mode, depending on how messed up it is exactly
10:42:26JdGordonhas anyone tried the mr500 or d2 sims recently?
10:42:28TheSevenno, it doesn't, I currently take everything from the nor flash's SCfg list and it works just fine
10:43:27linuxstbTheSeven: OK. Then I think your current approach would be best for Rolo - so it's independent of the bootloader.

10:48:10TheSevenlinuxstb: would you prefer a list-style or button-style menu?
10:48:50linuxstbAre you talking about a menu in the bootloader, or my suggestion of a "boot screen" in Rockbox itself?
10:49:15TheSevenboth
10:49:32TheSeventhey would probably serve similar purposes ;-)
10:50:19S_a_i_n_tlist-style would fit in better with RB would it not?
10:50:26*S_a_i_n_t 's two sents
10:50:30TheSevenmore points we need to take care of when using nor-based bootloaders are a) creating a backup of the old one, b) a way to easily update it and c) how to run disk mode etc.
10:50:31linuxstbThe answer would be different for technical reasons. If it's the bootloader, then I don't really care. If it's in Rockbox itself, it should use the existing menu widget, and hence you don't have a choice.
10:51:27linuxstbAt the moment at least, the bootloaders can't use any code from apps/, where all the Rockbox UI code is...
10:51:40TheSeventhey can :-)
10:51:45TheSeventhey just shouldn't...

10:54:41linuxstbTheSeven: My main question about the NOR bootloader, is whether we would want to make it compulsory - i.e. drop support for a NAND-based bootloader.
10:55:34linuxstbIf it's optional, then it can simply be managed by a Rockbox plugin, the same way flashing things to NOR happens for other targets.
10:56:31TheSevenactually the only way to bootstrap a nor-based setup would be through a nand-based thing, whatever it is
10:57:14TheSevenso we could of course just boot rockbox directly from NAND (that doesn't even need a bootloader stage in between) and flash the NOR bootloader from there
10:57:37TheSeveni wouldn't really advise anyone to use NAND-bootloaders for everyday use though, because of that FTL issue
10:59:34TheSeven("white screen of death" :-P )
11:00
11:00:24S_a_i_n_t"Please Restore Using..." ...*fuck!*
11:01:18TheSevenS_a_i_n_t: I even had some almost-bricked situations caused by that dumb bootloader, linuxstb also had one once
11:02:18TheSevenif you manage to put the FTL into a state where every try to write to the firmware partition just results in an I/O error, you have a *big* problem
11:03:17TheSeventhose were of course caused by rockbox bugs, but such things shouldn't *ever* be able to happen.
11:03:48TheSevenoh wait, nowadays we could just have used NOR DFU to recover from that :-)
11:04:00TheSevenbut we hadn't investigated that back then
11:06:25linuxstbTheSeven: So you think we should go NOR-only for Nano2G?
11:06:38S_a_i_n_tMy worst situation that I got into was "white screen of death" caused by simply inseting the USB cable that I couldn't get out of...the PC couldn;t see it and neither could ipodpatcher. But the battery diesd and after that itunes magically found it.
11:06:42TheSevenif we want to get rid of those WSODs, yes
11:07:29TheSevenhowever that means a more complex way than just "use itunes to restore" to go back to the factory state
11:07:55linuxstb"use itunes to restore" isn't our documented uninstallation method anyway.
11:08:03S_a_i_n_t*thats* one thing I think users could be dubious about...
11:08:09TheSevenbut it's the only failsafe one right now
11:08:49TheSevenNOR based bootloader + serious FTL screwup is a bit evil, too
11:09:43TheSevenyou would need to trigger a FTL reinit (in most cases this will happen when you just run disk mode twice), then manually reformat it the right way and extract rockbox again
11:10:11TheSevenit isn't really nice that you need to have a working rockbox installation to remove the bootloader

11:12:37linuxstbSo the NOR bootloader itself has everything it needs to restore, without reading anything from NAND.
11:14:05TheSevenit's all encrypted, so it won't be compressible
11:14:42TheSevenwe might fit a rockbox bootloader into the free space on the nor though (and just relocate things a bit)

14:26:24linuxstbnotlistening: If you can't find docs on a chip, you could look for a firmware update - that can often contain clues.
14:26:55Tornenotlistening: I am pretty sure nobody in their right minds would want to run rockbox as a firmware on a device with 1GB of ram which can boot win7.
14:26:58Torne:)
14:27:34notlistening:D
14:27:58notlisteningmore so a platford for something like android and rockbox app
14:29:04Torneyah. if we get rockbox as an app there may be vlaue in someone doing x86-specific codec tweaks
14:29:11Tornebut other than that there's no x86 porting :)

23:53:31linuxstbNo-one tagged the released bootloaders for the clipv2 and clip+? And they were called 1.0-RC ?

23:54:47ozzohmm using r25326 Clipv2 is playing nothing
23:55:24 Quit adnyxo (Ping timeout: 258 seconds)
23:56:09ozzoseems to be due to thefact that I generated a database on my pc
23:56:42ozzoafter using it everything gives out an Error Accessing Playlist Control File
23:56:45linuxstbHmm, and there's no manual for the clip+/clipv2 either?
23:57:12ozzohowever if I reboot and not use the Database everything is fine
23:57:22Zagordoes clipv2 need its' own manual?
23:57:38linuxstbYes, the installation instructions point to the wrong files.
23:57:46Zagorah
23:58:11ozzono man I just did the whole thing today and the instructions were perfect
23:58:38Zagorozzo: did you read the wiki or the manual?
23:58:46kugeldo we need different manuals? or could we put the installation so that it works for all?
23:58:48ozzowiki
23:58:57Zagorozzo: right. we're discussing the manual.
