#rockbox log for 2010-04-21

00:03:24CIA-5New commit by pixelma (r25692): Fix broken Iaudio M3 manual and missing buttons in the M:Robe 100 manual, caused by the same weirdness of tex: breaking a long opt list needs escaping ...

00:33:01b0hoonso it looks like after my last commits...
00:34:03b0hoonpixelma: but it builded for me locally for 5 different targets
00:35:21pixelmayeah for me too, just the M3 manual didn't build of the ones I tried. It's still weird, we'll see what happens tomorrow
00:35:49b0hoonpixelma: i wasn't aware of this, should i change the way of breaking the lines or wait?
00:36:02b0hoonpixelma: ah, ok
00:37:07 Quit phanboy4 (Ping timeout: 265 seconds)
00:37:26pixelmaI think I caught all the problematic ones. It's most important if you break \opt{pad,pad,pad,pad}
00:41:22b0hoonok, i'll pay more attension to this next time...
00:41:28pixelmayou'll sometimes see the % (actually a comment that helps "commenting out" the linebrak) at the end of \opt{bla}{blub} too because tex *sometimes* adds a space for the targets where this is not true. Then you'll sometimes see more than one space in the resulting PDF for all targets that are not included. Sometimes it works correctly though and I didn't find a pattern yet
00:43:10b0hoonyes. i was wondering what for it is.

03:48:21Unhelpfuli believe auto voltage scaling can be enabled separately... so we could just enable auto voltage and tweak frequency manually.
03:48:51Unhelpfuland somebody else must've told you some of it because it's news to me that we're nearly at minimum voltage at 264MHz

03:54:13n1sUnhelpful: i think it's near the minimum for that freq
03:54:37n1slower freq could use even lower voltage IIUC

04:09:13guston1s, and does it sound promising? i mean, can i remove the apple firmware after completely and use like described on the site (drag and drop files and play on the move)?
04:10:22n1sif rockbox is ported, you can drag and drop like to any other usb mass storage device
04:10:41gustoand what about the apple FW?
04:10:45n1sif you cna get rid of the original firmware completely is a detail of the port
04:10:57gustothat means?
04:11:15RadicalRBasically, the FW becomes optional.
04:11:18n1sso i can't tell you that now, it depends on how the bootloader etc is designed
04:11:25RadicalRThat too.
04:11:35RadicalRHowever, given the pattern of the Nano2g
04:11:53n1ssome of our ports have optional dualboot with the OF, some mandatory and some have only single boot
04:11:53RadicalRI think it's safe to say that it'll probably follow suit.
04:12:08n1syes, probably
04:12:48gustoand on the nano2g you can get rid of the original fw completely?
04:14:36RadicalRYes, I just keep it on just in case.
04:14:49RadicalRWell, hold on. Let me double check that.
04:14:59RadicalRIt goes to the iLoader

04:15:36gustoso you can delete the first partition where the fw is then, right?
04:16:30gustoand other thing that am interested in pretty much about this topic is what filesystems can you use then? only FAT32 or also ext2 and other?
04:16:52n1sonly fat
04:16:57RadicalRNix on the first one, and rockbox can only read fat
04:17:52gustois there a practical reason, or is it just because there is not enough ppl to write code for it?
04:18:54scorcherockbox supports FAT32 as well...
04:19:05 Quit Rob2222 (Ping timeout: 265 seconds)
04:19:17scorchegusto: the reasoning is mentioned here:
04:19:26gustobecause i think on such big storages like nano3g has with 8 GB and newer ones have even more a better FS would show up
04:19:52scorcheit isnt about "better" is about "compatibility"
04:21:35gustoah on that site the reason is, because these devices are too weak, have less RAM and other ressourcen, maybe that isnt true for modern ones any more, or will not be
04:21:50gustoyes, compatibility as well
04:22:12gustobut not everybody cares about compatibility, the oroginal firmware cares the less
04:23:00scorcheram is always a major concern...the more RAM we have, the more audio buffer can fit into there...the more audio buffer, the less we have to spin up or access the disk/storage...the less we have to access, the more battery life...
04:23:13gustoforcin ppl to use itunes to synchronize their ipod isnt exactly copmatibility improving
04:23:50gustoi understand that
04:24:38gustois on routers the same
04:25:05gustothe more free ram you have, the more nat connections you can route through
04:30:16n1sthere also is not a big gain in a "better" fs for most people, as fat* works pretty well
04:32:12LloreanThere's really not a very strong reason for moving them to more 'advanced' filesystems anyway. Most of the better features don't relate to the use of it as a portable music player, while FAT32 as a filesystem is pretty much understood by any modern host computer making Rockbox as a UMS device pretty much universally compatible (or as close as you really can be)

08:53:02RandomInsano1linuxstb: tcctool is compiled, have some firmware images. I just need to open one of my devices and configure it for usb boot mode
08:53:48linuxstbRandomInsano1: A lot of devices enter usb boot mode via a button combination - yours don't have that?
08:53:50RandomInsano1As far as target, TCC8200?
08:53:58linuxstbI meant which MP3 player?
08:54:31RandomInsano1Insignia NS-DV2G specifically. There's a solder jumper on the board.
08:55:28RandomInsano1It looks to be nearly identical to the iriver x20
08:55:41linuxstbThe main problem with the telechips targets is the software flash translation layer (FTL). We don't have a reliable read-write driver for that (and it is also slightly different on different telechips devices).
08:55:48RandomInsano1Hardware wise at least. Boards are layed out differently
08:56:09RandomInsano1I have a MicroSD at least
08:57:02RandomInsano1I'm interested in getting as far as I can with it. When I get bored or hit an impossible wall, I'll give up.
08:57:17linuxstbThat's what we all do ;)
08:57:36 Nick dys` is now known as dys (
08:58:30RandomInsano1It's kind of interesting, someone who owned an iriver was able to use my firmware on it nearly perfectly, but without sound. Also, the images if the development board show a lot of the same chips as the final product.
09:01:23RandomInsano1Is the CPU_FREQ define in decimal? I'm stealing the Cowan D2 config file and it's set to 48000000
09:03:35linuxstbYes, but that define may not actually be used to set the CPU frequency - it depends on the driver. It's used to display the CPU speed in the debug menus. (IIRC). So don't worry too much about it for now.
09:03:58RandomInsano148000000 it is then.
09:09:11*pixelma wants the "simplify PLA" patch in - :\\
09:09:23linuxstbRandomInsano1: If I was you I would start by disassembling the original firmware, and find the code that does the initial hardware setup - it should be the first functions being called. You can then compare that to the Cowon D2 code (7800) and see how similar the 8200 is.
09:10:36RandomInsano1I don't know if my one Comp Sci class on assembly language has given me a firm grasp of things, but I'll give it a shot.

12:08:56JdGordonwhat else is needed for it?
12:09:09kugelI don't really like the patch. it has to work with that strange buffer layout which makes it a hack in many places and very error prone
12:10:16JdGordonyou know that is very simple to change if the logic to check buf size requirements on images is there right?
12:11:00kugelthere's also the tokens array
12:12:34jhMikeSwodz: any luck? I have another thought. perhaps starting a new AD conversion on its own int is producing an int flood? a tick task may be more appropriate.

12:15:07hobbshey look at that

12:42:45hobbswhat a coincidence ;)
12:42:47jhMikeShobbs: throught the DVFS system or straight register setting?
12:42:57hobbsthe latter
12:45:11jhMikeSI've got voltage scaling, confirmed at the test points by a multimeter. The DPTC, there's latency issues with updating regulator settings. I may commit without that part enabled which would fix it at 1.6V for 528MHz and 1.35V for lower frequencies.

12:46:10wodzjhMikeS: Play button is plain GPIO in MPIO. I might change buttons mapping play->select and comment out whole ADC stuff. This way we can eliminate (or confirm) that problem origin is ADC interrupt
12:46:29hobbsjhMikeS: what range of speeds?
12:47:50jhMikeShobbs: 528, 264, 132, divider only. There is a bug with PLL switching, fixed in r2.0 that forces DVFS to reset the PLL. Perhaps because audio uses the USBPLL, 399 may be workable since that requires using SRPLL.
12:49:53hobbswhat about dropping the PLL once at boot and using 66-264?
12:50:33hobbsthat's essentially where I've ended up with my manual switching

12:54:38jhMikeS264 won't always cut it for everything. the automatic switch works pretty well and is basically delay-free. we could divide further for 66, but there's other warnings in the errata manual about that. Also, changing PLL changes the SDMA core frequency.
12:55:46jhMikeSof course, the issues are clocking-relative issues, not absolute frequency ones
12:57:19hobbsyeah, I didn't have luck with 528/8 = 66, but I did with 264/4 = 66. And... well, let's say I haven't run into the stuff that needs more than 264 yet.
13:00:10wodzjhMikeS: I commented out whole stuff related to ADC and this doesn't remove delay between selecting menu item and entering that menu item
13:00:42jhMikeShobbs: 528/8=66 will set it to CPU=AHB, which is what the bug is about (iirc). amiconn uses it at 528 with APE.
13:03:10hobbsbleh ;)
13:03:38hobbsoh well, always possible that 66 is no big win I suppose
13:03:43jhMikeSat least with the DVFS you just set PMIC pins to select a different reg. setting. no SPI writes are needed.
13:05:33jhMikeSit benefits from voltage reduction more than frequency. I tested at 528 and 264 at 1.6V and got the same batt life. in both cases. simply changing F seems to just make it take longer/short roughtly in proportion before reaching an idle state and everything's been done to keep the ARM core as idle as possible.
13:07:29*jhMikeS , besides complaints about the S with OF, noticed people not being too impressed with Zune battery life either, with a 800mAh batt no less.

13:19:00hobbsnow you're making me think my voltage setting isn't
13:19:07jhMikeSn1s: Perhaps it could go a touch lower running so slowly. FS never does it though.
13:20:00n1sjhMikeS: do you know what the OF does?
13:20:13jhMikeShobbs: only 528MHz (aka. "turbo" and "overdrive") needs DPTC to find the minimum. <= 400MHz only requires 1.35V.
13:21:01hobbsright, but I'm running lower. Unless I'm not because I did something wrong there
13:23:01jhMikeSn1s: It leaves SW1ADVS set at 1.4V. I haven't tracked that part down in the driver. It's sort of a mess to wade throught. I'll try to find out.
13:23:19pixelmajhMikeS: about your repeat question. To me it doesn't sound like it has to do with repeat, more like playlist settings. Did you check your "recursively insert directory" settings or maybe you had auto-change directory set before or something?
13:23:53hobbsI suppose I can try changing all the values to 0.9V and make sure I get a hang. That should be fairly harmless ;)

15:40:14TornejhMikeS: you mean the software eq, or the tone controls?
15:40:24Tornei fixed the beast tone controls the other day :)
15:40:24jhMikeSTorne: software EQ
15:40:45jhMikeSit sounds like wrapping noise, but not so severe
15:40:56hobbsjhMikeS: does letting the GPT count during WFI use more power or what? Because timing is so much more consistent with it on
15:41:10jhMikeSperhaps just one band or something, and precut has no effect on getting rid of it
15:41:16TornejhMikeS: btw, my housemate is interested in working out how to get rockbox to use the beast's DAC's EQ directly
15:41:33Tornei suggested he should probably come on irc and chat to people
15:41:48Tornesince it's mostly a UI issue, if i understand correctly
15:42:04Torne(hardware EQs being similar, but not identical, to each other or our software EQ)
15:42:10jhMikeShobbs: I have no info on that. I just expect it's unneeded and if you're busy waiting, it's not in WFI mode.
15:44:08jhMikeSTorne: Personally, I'd say have a "hardware EQ". Llorean was objecting saying such a thing was confusing. The best compromise I could think up was having 5 "tone controls". Really, it was always an interface thing more than a problem to make it work. I don't care to use them half-assed as bass and treble. We should use that EQ.
15:45:18jhMikeSIf we don't we're just jailing the HW a bit and I thought we were supposed to do the opposite of that :)
15:45:35Torneif someone did the effort to use them as bass and treble, we might as well have it, though, no?
15:45:45jhMikeSeven the gain limiter could be hardware

17:43:07amiconnAuto-change makes a new playlist from the next directory if the old one ends. Repeat all causes it to never end...

19:36:57n1slots of esotgeric options we do have

19:43:21jhMikeSI don't even think we have multiple-selection lists and I'd love that for managing files on the player when away from any other means.
19:45:05n1sno, we don't, it's a feature i would love too
19:45:16Lloreann1s: The thing is, if you click on a file, and expect playback to continue through the folder, some people can (quite reasonable) expect new additions to the folder later (for a podcast folder, for example) to be played.
19:46:36n1sLlorean: but doesn't inserting a dir into a dynamic playlist do that?
19:46:49jhMikeShmmm...but what would dropping ACD do? I don't mind the option to stick with playing an album from the browser or just play everything I've got. No database init = more RAM too.
19:47:29jhMikeSLlorean: you mean if they move a file into a directory that is already playing through?
19:47:40Lloreann1s: If you "insert" the dir, the playlist is a list of filenames isn't it? It's an unsaved playlist, rather than an index in the folder?
19:47:46n1sjhMikeS: from the times i've looked at playback or playlist code, the dir handling seems to need quite a bit of special cases
19:47:53LloreanIf I recall, if you insert a folder with subfolders, you can't bookmark until it's saved.
19:48:41LloreanjhMikeS: Say you click "select" on podcast 3 of 5 in your podcasts folder rather than using "insert" to add it in a playlist.
19:48:52LloreanYou get through 3 and part of 4, then stop, then add a podcast six from your computer, then resume.
19:49:05LloreanI'm pretty sure as long as you don't manipulate the playlist playback will eventually reach #6 right?
19:49:15jhMikeSn1s: I can't fathom why it needs 3581 lines of code! of course, what's most of it dealing with?
19:49:29LloreanBut if you "insert" the folder instead, you'll insert the 5 individual items, and when a sixth is added to the folder, unless you also insert it, it won't show up in your dynamic playlist
19:50:48n1sLlorean: i'm not sure but IIRC as long as the playlist is unsaved it is "dynamic" and then it just keeps info like inserted dir foo, inserted file bar so if a dir is inserted and later changed and the playlist is not saved, the new contents of the dir will be included too, i might be wrong of course
19:51:41Lloreann1s: I'm not necessarily saying the change would be bad, just unexpected for some.
19:51:51n1si think this is the cause of the "deleting a file in the dynamic pl will cause resume to pick the wrong file bug"
19:51:59LloreanFor example, if we got rid of the directory index based playback entirely, you'd never get the whole "it resumed in a different file I stopped" bug
19:52:34n1swell, apparently we have unexpected behaviour either way :)
19:52:42Lloreann1s: I'm pretty sure those are playlists created by simply pressing 'select' on a file, rather than using "insert"

19:53:41LloreanAnd it does allow the nice behaviour of being able to have a playlist that continues into a file that wasn't there before, but that's about the only positive I think.
19:53:46n1sLlorean: anyway, multi select is something i would really like
19:54:08LloreanMe too
19:54:56LloreanI'd also like to split "right" and "select" one day, so that one could actually be "invoke what is highlighted" and the other could be either "insert" or "select" or some other list action.
19:56:41pixelma the index way is also a lot faster I believe (I always thought this is the reason)
19:56:59 Quit xiainx (Quit: Good Bye)
19:57:44LloreanYes, an "insert" takes a bit for it to iterate through and insert all the files
19:58:13LloreanBut couldn't playback start based on the index when you 'select' a file (since at that one point, we know it's constant) then the iteration to populate the playlist happen after?
20:00:37pixelmahmm... it could also be from the time resume info and other settings where stored in a hidden sector and space to store something was quite restricted?
20:00:49pixelmacould be I'm confusing things though
20:01:05n1sLlorean: yeah, it could, this would also help the case where people select a file in the database from a view of all their files, which causes al those files to be inserted into the pl before playback starts
20:01:45n1si think we would need a pl worker thread then though

20:49:25jhMikeSwhy they have DPTC tables for frequencies where DTPC isn't necessary is a bit perplexing. one driver version only has tables for overdrive, has checks for imx31 rev 1, sets voltages to 1.25V for dvs yet rev 1 can't use that, supposedly, according to the other drivers. there's even another version I found online.
20:53:33jhMikeSthen there's that SDMA stuff, where it has checks in the BSP for rev 1.00, and code! but elsewhere it says it was never a production part. nonetheless, that was much easier to sort out and I can probably remove that overhead from the compiled binary.
20:56:28n1si hope we can assume all the beasts use the same chip rev?

20:57:19jhMikeSn1s: I think, but I haven't assumed that. It might be plain irrelevant if 1.00 was only a prototype.
20:58:43jhMikeSn1s: It was probably no longer made by rev 2.00 release anyway, thought I'm not certain. If the latest fw image doesn't handle the case, it's no issue.

21:17:19pixelmaTexasRockbox: store them away in a different folder, if you really need to you could set the folder to hidden and only let it display "supported" files
21:18:19TexasRockboxStore all the cover art in another folder?
21:18:34*jhMikeS wants to show hidden files while only browsing supported ones since hidden ones can be supported, or he's just being too demanding.
21:19:30TexasRockboxAll of my cover art files are call cover.jpg and reside in the folder where each album is located.
21:20:04archivatorTexasRockbox: see the manual, C.3 - it''s possible to have everything in one folder, you'll just need to rename the files.
21:20:44pixelmaTexasRockbox: there is one way you could store it one folder and still have it found. (I believe an "albumart" folder inside .rockbox, the AlbumArt wiki explains it. But you need to rename the cover files to artist-album.jpg or so
21:20:46TexasRockboxYikes! 800+ files
21:21:35TexasRockboxIs it known where in the code where I can add .mpg to the list of supported music files and have the video play instead?
21:22:27TexasRockboxI did try changing the extention of the video file to .mp3 and that didn't work
21:23:09pixelmayou mean that they show up if you set your file view to "Music"
21:23:30pixelmajust for clarification, I had to parse the sentence a few times
21:24:55TexasRockboxIf I change the extention of the video file the file shows but does not play. If I leave the extention to .mpg the file isn't visible unless I select show files "All" or "All Supported".

21:41:44jhMikeSamiconn: I'm not even clear on what that is (as a 'method' per se)
21:42:35amiconnThe archos OF had a limit of 999 files per playlist for that reason, and its playlist generation was so slow that early versions even went into idle poweroff before staring to play if you actually tried to add that many files

21:56:46TexasRockbox@new_bee Great! Please feel free to contribute, work is ongoing and any help is appreciated
21:57:38jhMikeSn1s: that just it, how to rematch the index, if index method isn't abandoned (and I suspect it won't be so easily).
21:57:44n1sarchivator: you could try increasing the delay before first battery reading in powermgmt.c:648
21:58:16amiconnImo being slightly off in rare cases (how often do you add/remove stuff from your dap *in the current folder*?) is much better than being slow *every time*
21:58:51jhMikeSwe should probably have find voltage reading compensation while spinning, speced for each battery, just like the charging curve

22:01:22pixelmaI've heard of people storing all their tracks in the root folder and you wont know with e.g. iTunes stored music getting off topic a bit). I'm all for keeping the quickest method and never had a problem with deleted files, just stating why the discussion came up
22:01:34n1sanyway i meant to store the filename in addition to the index so we match index like we do now but then also check the filename
22:01:51TexasRockbox@llorphone yes it does but I use album art in the album subdir and I don't want to see the .jpg

22:02:58n1samiconn: ok, so it isn't perfect but better than what we have
22:03:09pixelman1s: resume info will probably stored from the folder name still?
22:03:09amiconnIf it's id3v2 and the tag editor has to change the tag's size, that essentially means a copy operation, which can only be done using a tempfile
22:03:25TexasRockboxThe idea is just to have only music and video appear
22:03:27n1sthe common case for this seems to be people who listen to podcasts and then deletes them
22:03:50Strife89Is there any work on using the Broadcom chipset in the iPod Videos?
22:04:02Strife89A patch, for instance?
22:04:12amiconnWell, if you delete old entries while the folder is still playing, things *should* keep working as expected

22:04:26jhMikeShow's this stuff sorted if it's up to the fat which order the files are found? it seems names have to be dealt with in some way.
22:04:43Strife89n1s: Ah.
22:05:18n1samiconn: i think more like listen, stop, connect to computer, add and delete a few podcasts, resume, bang
22:06:27amiconnNever happened to me but then I've never listened to a single podcast on any device other than my computer
22:07:17*amiconn isn't sure how the name -> index assigment actually works

22:14:54*jhMikeS refrains from giving some of the many possible retorts to that :P (too political)
22:15:01fmlamiconn: then the playlist creation would still be fast, but playlist manipulations were also better detectable
22:15:10amiconnThen change it in a way that doesn't make it worse for those cases where it works well
22:15:51amiconnThose cases are still the majority... and for the podcast case there is a workaround
22:16:12n1si think storing the filename of the currently playing song is a good compromise, and give up if the name and index doesn't match
22:16:12n1sbut no, i don't care enough to do anything about it
22:16:20amiconnInsert the podcasts individually instead of playing the first track in the folder
22:17:10n1salso if people think about the problem, maybe someone will come up with a way that is both fst and more reliable
22:17:16amiconnTe resulting list will load slower (probably not noticeably provided there aren't too many podcasts in the folder), but position will always be correct
22:17:28jhMikeSamiconn: what do you mean "your current position"? I wouldn't think it would change if a playlist were a perfect duplicate.
22:17:29fmln1s: the background thread could e.g. ensure that two files around the current position have the names stored so that small shifts are recoverable

22:18:07amiconnIf you invalidate the list and I have to re-create it, it would play from the beginning

22:23:24fmlamiconn: so it's possible to have multiple threads on hwcodec? From you reply I thought it's impossible. But if it's possible we could have another thread (or use an existing one) for updating the playlists (adding file names to the current position and around it)
22:23:27pixelmadon't bookmarks still work even when tracks in the folder get deleted?
22:23:29jhMikeSindex and offest and tossed inti global_status

22:24:33fmlamiconn: I didn't know it exists on swcodec :-)
22:24:56n1spixelma: i think they are filename based
22:25:11amiconnIirc it was introduced to solve a problem with trackchange on swcodec (and that doesn't affect hwcodec, obviously), so it would be a waste to have it on hwcodec
22:25:27amiconnAfaik it has nothing to do with playlist creation
22:26:42amiconnThreading itself dates back to the beginnings of rockbox (without priorities and stuff like that)
22:27:20fmlThen I think we could hijack a thread for that. Not every thread is heavily busy all the time.
22:28:13amiconnHwcodec still has thread priorities disabled, since there is no reason for this so far
22:33:26jhMikeSit's there mainly to ward-off audio breaks during user activity like scrolling which I can't see HWCODEC having an issue with since it just sends MP3 data with an ISR

23:52:48domonokyarchivator: for the log: if i replace the voicescript->waitForReadReady() call in TTSSapi::voice with a loop which waits till i can read a line, the progress info works again, also the error message is gone. But i noticed a new problem: if i abort while voicing rbutil completly hangs up.
