01:09:03kushal_12_27_200hey JdGordon, have you noticed the "refreshing database" problem in any sansa c250 recently? The OF in mine is locked forever in that screen and the only way I am charging it is by pressing select when connecting it.
01:17:44 Join Slack [0] (n=brett@12-218-63-169.client.mchsi.com)
01:20:29JdGordonI dont have a c200
01:23:44pixelmaI have one but didn't notice any problems like this. Also on my c200 the database refreshes when I disconnect USB not when I connect

01:33:31 Quit Thundercloud (Read error: 104 (Connection reset by peer))
01:34:52kushal_12_27_200Pixelma,that is what normally happens with mine too. However, it has been acting a bit strangely lately. I had to press power button for over ten seconds for it to turn off because the refresh was taking too long. It was over an hour of waiting and I finally went ahead and turned it off by holding the power button. Now, it wants to refresh database when I turn it on.
01:36:52kushal_12_27_200JdGordon, I noticed you closed something on filespray for a (seemingly) related incident. (Do you want me to find it?)
01:42:16pixelmafrom your description I would suspect a problem with the OF (maybe filesystem ones too), having read somewhere that the OF's database refresh can choke on some files too. My best guess though and I'm off now

07:32:51syn4psei'm running into trouble using 2 arrays of 6400 char, even though it is defined globally. this will be a full array (a maze). is this due to a limitation in memory?
07:33:14syn4pse*they are , that is
07:33:28JdGordonwhat sort of trouble?
07:33:48syn4psewell, when i access the full array, i crash pretty miserably
07:34:02syn4psebut if i just use a portion of the array(s), i am fine
07:34:20JdGordonthats not a very big array, so assuming your accessing it correctly there shouldnt be a probleem
07:34:29syn4psei must be handling it wrong
07:34:53syn4psei'll keep on banging away at it.
07:35:26syn4pseanother thing, it only crashes on my ipod, not on the simulator
07:36:39syn4pseso i'm not close to a limit? that's only 6400*1*2, 12800 bytes, right?

07:37:52LloreanWhat sort of crash?
07:38:10syn4psethe screen flashes and the ipod powers down
07:39:52LloreanAnd you've gone through step by step to figure out which line, exactly actually crashes on?
07:40:14syn4psei can't crash it on the simulator, unfortunately
07:40:17syn4psenot for lack of trying
07:40:33syn4psei'd love to crash it in gdb :)
07:40:44LloreanYou don't need GDB to go line by line.
07:40:55syn4psei'm a little new at this
07:41:17LloreanYou could guess where you think it is, put a prompt for a keypress in several places that also display a recognizable string, see how many strings you get to see before the crash
07:41:22LloreanThen narrow it down similarly
07:41:33LloreanIt's not ideal, and if you've got a lot of iterations it could take a very long time.
07:41:52LloreanBut if you honestly can't figure it out by analyzing the current logic it at least gives you a way to prod at it.
07:42:00syn4psei have an idea where i think it is but i can't seem to figure out my logical error.
07:42:05syn4pseit's frustrating :)
07:42:41syn4psei'll try that

11:22:02sunnyday[m]hi all
11:22:46sunnyday[m]I have installed Rockbox on my Iriver h10, but ums wouldn't work automatically. Why this?
11:23:39n1ssunnyday[m]: because rockbox doesn't have usb support on that player yet
11:24:45sunnyday[m]I see, then why in the manual they say after installing Rockbox it will run in ums mode?
11:27:07n1ss
11:27:11ghensunnyday[m]: afaik ums functionality is in the iriver firmware
11:27:17ghenI converted mine to ums before installing rockbox
11:27:20ghen(one time operation)
11:27:58sunnyday[m]how did you do that?
11:28:12sunnyday[m](it is the 20 gb model)
11:28:14n1ssunnyday[m]: since you don't say which h10 you have i don't know exactly but the manual for thr 20 GB version clearly states that you need to press a couple of buttons to get UMS
11:28:59sunnyday[m]yes, but I thought after installing the Rockbox's bootloader I wouldn't need to press the select key anymore

11:30:09ghenbut you can permanently replace the iriver bootloader/firmware with a UMS one

13:50:37linuxstbwebguest58: Has the radio ever worked in Rockbox? Does it work in the original Sandisk firmware?
13:52:13webguest58I had to chance the firmware to europ with fm but then it appeard on the display
13:53:28linuxstbYou didn't answer either of my questions...
13:57:09webguest58OK no with the original firmware it did'nt work so i chanched the sansa firmware to europ with fm ( no sound) then i put rockbox on my player and still no sound
13:57:55Tuplanollayou mean it didn't work even with the european firmware?
13:59:20webguest58Yes i can see the frequentie but i can't hear it

15:24:03linuxstbWill it be possible to map the two blocks of RAM together? Or will we have to split the usage?
15:24:15funmanI mean not after I corrected it - but physical disassembly shows a 8Mb SDRAM chip, and the OF has a '8MB' string
15:24:23funmansplit
15:24:54JdGordonis 320 enough for the codec ram?
15:25:19funmanthe different aliases are not consecutive
15:25:21linuxstbNot currently - the codec buffer is 1MB
15:26:34JdGordonon the e200 at least thats probably not a big deal if we dont use that 320
15:27:03JdGordonI guess the m200 could use that for plugins, low mem targets get less plugin ram anyway
15:27:16funmanI bet the 320kB RAM is faster than the SDRAM
15:27:22*preglow wonders why we would possibly want to put settings in a plugin

15:28:54JdGordonbesides.. its an idea, and one which isnt likely to happen anyway, except if we are forced to dump some bin weight
15:28:56saratogaassuming the IRAM is SRAM internally, it should be treated like IRAM on the other targets

15:31:00preglowi find people to be much more reasonable then

15:34:10 Quit IudeX ("CGI:IRC")
15:34:10JdGordonhow much iram is there usually?
15:34:19preglow64k-128k
15:34:25funman20 - 65MHz operation
15:34:34funmanthere is 5 64KB blocks here
15:34:45preglowfunman: so it's not necessarily single cycle, then
15:34:55preglowthat explains the amount a bit better than moore's law
15:35:11preglowdram is way more compact than sram
15:35:21funmanand way more slower ?
15:35:25preglownot necessarily
15:35:48linuxstbfunman: The extra RAM also solves another problem - where in RAM the bootloader loads the main Rockbox image to. We can now simply keep the bootloader in the 320KB RAM, and load the main Rockbox image to the start of the 2MB RAM.
15:35:48preglowbut most of the single cycle iram you will see is sram
15:36:26funmanlinuxstb: doesn't some rockbox code need to be loaded in IRAM for speed ?
15:36:28saratogatheres also 1T DRAM which can be used in place of SRAM in some situations
15:36:45linuxstbfunman: Yes, but that's done by the main Rockbox crt0.S - it relocates parts of itself to IRAM.
15:36:46funmanwhat's the '1T' for?
15:37:14funmanfor sure it's not 1 TeraByte
15:37:35preglowdunno what it stands for, but it's essentially a dram design without the explicit use of a capacitor element for the the memory part
15:37:49preglowuses paracitic capacitance instead
15:37:56preglowwhich is rather clever :)
15:38:21saratogaI think its "1 tick" as in single cycle
15:38:28preglowhmm, nice
15:38:39funmansaratoga: the AS3525 datasheet mentions 1T DRAM
15:38:49preglownever seen it myself, just briefly heard of it
15:39:05funmanjust buy a Sansa Clip to see it in action ;)
15:39:28preglowJdGordon: nah, this is lower level than i've been in the pcm stuff
15:39:31preglowJdGordon: what is it for?
15:39:32*linuxstb points to wikipedia http://en.wikipedia.org/wiki/Dynamic_random_access_memory#1T_DRAM
15:39:42saratogahopefully the 1 T DRAM is the same as SRAM for our purposes
15:40:09JdGordonpreglow: nuts :p well the idea was to be able to mix seperate pcm buffers as late as possible to get around issues like no voice while paused
15:40:23saratogahaving all this IRAM would be very nice
15:40:42saratogai think the awful performance per clock on the gigabeat F is due to lack of IRAM vs. PP
15:41:02saratogaif so, the AMS chips would be much faster then the Gigabeat F in most codecs
15:41:53amiconnThe gigabeat F/X has similar performance per clock as the PP chips, as it's (only) armv4t as well.
15:42:46amiconnThat's why the beast can handle ape -c4000 w/o problems at 264MHz, while the gigabeat F can't, even at its higher clok
15:43:12amiconnOh, and on the F/X we don't use the available IRAM at all...
15:44:20saratogaamiconn: i remember looking at AAC/Ogg performance a while back and being surprised how much better PP did
15:44:51saratogaI think the Ogg needed something like 60MHz per 1x of realtime, vs. <40 for PP
15:45:05saratogaand this is inspite of the ARM9 load/store improvements
15:46:06saratogahmm the 65MHz speed on the AMS's IRAM means its probably not single cycle then

15:49:40funmansaratoga: where did you buy your JTAG connection ? I think I'll get one (if I get it too late for development, at least I'll use it to unbrick my other Clip)
15:50:18kugelAre they on a e200? I want to use it for an experiment and need to know the precision for the error analysis
15:50:18moosGodEater: yup
15:50:46GodEaterso does fixed.cfg get completely wiped if you use the "reset settings" feature of the bootloaders ?
15:50:53saratogafunman: i picked some random ebay shop, and they shipped it from china
15:50:53GodEateror just ignored ?
15:51:12JdGordonGodEater: fixed.cfg should never be written to by rockbox
15:51:13preglowJdGordon: well, good luck on that, it sounds like something we want
15:51:13saratogabut theres a few places on google for about 10 USD
15:51:34GodEaterJdGordon: so if someone does a settings reset, will it then be ignored that time ?

15:51:49preglowJdGordon: but how to handle dsp when? will it only be applied to the main pcm buffer?
15:51:59preglowas in the one that does music

15:52:30GodEaterJdGordon: that's my point, when you do a settings reset, that's done at boot too
15:52:45GodEaterso I'm wondering if the fixed.cfg could cause issues if someone forgets they've made one
15:53:09amiconnkugel: Timers are implemented correctly on PP, so there's just the +/-0.01s quantization error, plus the clock deviation which depends on the individual unit and is also temperature dependent.
15:53:20JdGordonpreglow: the dsp is only used for music currently isnt it? does it make sense to put the voice audio through it?
15:53:25funmanhttp://cgi.ebay.com/JTAG-Programmer-Adapter-Test-Debugger-PCB-JTAG20-Cable_W0QQitemZ350115670034QQcmdZViewItem?hash=item350115670034&_trksid=p3286.c0.m14&_trkparms=72%3A1240|66%3A3|65%3A12|39%3A2|240%3A1318 looks legit
15:53:33linuxstbGodEater: "reset settings on boot" isn't a bootloader feature - it's done in Rockbox itself.
15:53:40amiconnTypical error is a few seconds per day, like any digital watch/ clock
15:53:42preglowJdGordon: i don't know, really, i kind of thought it was applied globally
15:53:49JdGordonGodEater: umm yeah, if they reset at boot it could, I thought you are talking about resetting from the menu
15:53:58preglowJdGordon: well, it depends, would you expect the voice ui to get more treble if you adjusted the treble setting?
15:54:12preglowJdGordon: i kind of would expect something like that to apply globally
15:54:43linuxstbIsn't DSP needed for resampling voice?
15:54:48preglowthat too
15:54:52preglowhmm, yeah
15:54:56preglowthere's different dsp for voice now
15:54:59preglowremember now :>
15:55:18*GodEater makes a note of this info in his "possible gotchas" list
15:55:22amiconnpreglow: Imo some dsp settings should apply globally, but not all (e.g. channel configuration - e.g. voice would be muted when karaoke would be applied to it)
15:55:31preglowamiconn: very good point
15:55:35JdGordonlike I said... im way out of my depths here.. I figure if I get a base working either someone can help out, or take over...
15:55:54preglowJdGordon: jhMikeS has/had plans for a very nice mixing system
15:56:02preglowthat would also solve the current issue we have with dsp latency
15:56:08preglowbut it would require some fairly nice changes...
15:56:20linuxstbpreglow: Can you remember what his plan was?
15:56:50preglowonly that it involved moving dsp very late in the chain and almost certainly would require preemptive multitasking, tbanks to the latency :)
15:57:04JdGordonI couldnt find the discussion, but from what i remmeber im sort of close to it?
15:57:51amiconnpreglow: I don't think we need preemptive multitasking. It would open a whole can of worms for almost no benefit. Just mix in an isr, using small blocks
15:57:56jhMikeSamiconn: you panged?
15:58:07preglowamiconn: might work, yes
15:58:19preglowbut i'm still not convinced preemptive multitasking would be bad for rockbox
15:58:35JdGordonGodEater: it that something which we should fix? I cant image fixed.cfg is actually used by many people and especially not to set dangerous settings
15:58:36*jhMikeS hears "preemtive" and his rabbit ears perk up
15:58:46preglow:D
15:59:27amiconnjhMikeS: Yes. I have a strange mpeg2 video, which triggers 2 bugs in mpegplayer, a visual bug and a freeze bug
15:59:52jhMikeSamiconn: hmmm...unusual in which way?
15:59:52saratogafunman: check the shipping label, and thats where i got mine
16:00
16:00:00preglowit would be a very fun experiment anyway, one i hope jhMikeS will embark on one day :P
16:00:04saratogafunman: I mean to say that I checked my label and its the same
16:00:25amiconnThis video has a max timestamp of 0xffffffff, but its min timestamp is > 0
16:00:39amiconnSo the difference is smaller than 0xffffffff, i.e. not invalid
16:01:22amiconnThis causes the total playtime to be displayed as 26h 30min nn sec, which is too long on the X5 with 12-Nimbus and overlaps the icon in the center
16:01:27GodEaterJdGordon: I don't know, it only just occured to me
16:01:51amiconnIt also causes a hang with the disk spinning if you seek past the actual end of the video (video is ~15 min)
16:02:04jhMikeSamiconn: how long is the video in reality?
16:02:11JdGordonAm I wrong in thinking that if the DAC is set to 44.1khz then it will keep hitting the isr to try and stay at that rate regardless of how small the buffer it gets each time is?
16:02:13jhMikeSheh
16:02:37preglowi think the isr always assumes it gets what it asks for
16:03:02preglowat the lowest level, of course...
16:03:25 Quit Darksair ("Reboot")
16:03:32JdGordonbecause (At least in the sim) if i fill 32k sample buffers it seems to work about right, but if that drops to 2 or 8 k samples it goes completly bad
16:03:45jhMikeSamiconn: I know min timestamps are quite often > 0. Things should be handled as unsigned.
16:04:10amiconnjhMikeS: Yes, and they are. Problem is that the max timestamp doesn't match reality
16:04:18linuxstbAren't mpeg timestamps something unhelpful like 33-bit?
16:04:20amiconn...and that causes trouble in mpegplayer
16:04:37jhMikeSlinuxstb: yeah, but we use 45KHz and so ignore the LSb
16:04:44funmansaratoga: thanks. how long did you wait for the shipping to arrive?
16:05:23jhMikeSamiconn: so the final stamp of 0xffffffff is actually valid for the file?
16:05:25amiconnWindows media player also has trouble playing that video. The file was produce by nero vision, and I'm sure there are no bit errors in it
16:05:40amiconnjhMikeS: no
16:06:00amiconnIt should be much lower. I guess 0xffffffff actually means invalid

16:12:36preglowJdGordon: a fine development method i tend to follow myself :P
16:12:42pondlifeIt's sometimes good to start with a list of requirements at least - once you get to that point.... and then an API for the new PCM layer...
16:12:51JdGordonpondlife: in all honesty I didnt design anything propeerly because I didnt eben know if I could get this far

16:14:23preglowpcm, playback, def
16:14:25preglowplaylist, i dunno
16:14:35*pondlife thinks we should scrap "apps" and have a set of layers
16:14:47preglowwell, the current way is just two layers
16:14:54preglownothing fancier than that

16:16:09pondlifeWe could do with more modularity, really. Currently we have just C function scope holding APIs together, might be useful to make it more explicit.

16:49:58funmanthere is also the difference between Program streams and Transport streams
16:50:12linuxstbIIUC, mpeg is just a stream of packets - there's no concept of duration, and timestamps can be discontinuous.

19:02:30amiconnn1s: It's probably worth checking out the dynamic method. As long as core voltage is fixed (Coldfire, PP, ..), frequency<->current relationship is (approximately) linear, but once dynamic voltage adjustment is added to the mix, the relation becomes (approximately) quadratic
19:02:40bertrikI think amiconn once told me that in PP devices, all clocks basically switch when boosting. It looks like we can avoid this on the as3525
19:03:08bertriki.e. keep peripheral clocks at the same frequency and boost only the cpu
19:03:25n1samiconn: I'm reading the data sheet but my hope that i will be able to implement this is low.
19:03:25 Quit jhulst (Read error: 110 (Connection timed out))

19:04:44amiconnWith that quadratic relation, it's better to dynamically adjust the clock than to switch back & forth between 2 fixed frequencies
19:05:09bertrikwe should be able to do this on PP502x already...
19:05:22amiconnbertrik: We're talking about the beast here
19:05:42amiconnAnd we cannot do this properly on PP
19:06:54amiconnWe do not know the core specs, and hence we have to assume that the required core voltage is fixed.
19:07:55bertrikok, you mean it will involve guesswork to know what voltage is required at what frequency
19:08:54amiconnYes, and there is no guarantee that a voltage that is sufficient for 30MHz on individual device X will be sufficient on individual device Y
19:09:58amiconnEven the fact that the voltage is changed on the fly could cause crashes or other erratic behaviour
19:10:41amiconnThe beast is a completely different matter because we (a) have the datasheet and (b) this datasheet tells us that the core has dynamic voltage adjustment designed into it
19:11:35bertrikgoing back to the clip, I think a good first try would be to keep the peripherals at a fixed frequency (determined at compile time) and vary only the cpu frequency at run-time
19:11:43 Part Aduch
19:12:57bertrikwe'll need to know if any peripherals have any special requirements though (like certain maximum cpu/peripheral clock ratios etc.)

19:52:23n1swell, at least setting different clocks works
19:54:14bertrikfunman, sorry don't know what goes wrong. The datasheet mentions something about using a pre-defined order when switching clocks but doesn't further specify it.
19:55:16funmanmaybe to be sure to not exceed the mentioned requiremens
19:55:33bertrikAlso, there may be a problem with synchronisation between the peripherals the cpu clock when they are not running from the exact same clock, so we probably need something other than the fastbus mode of the cpu.
19:56:14funmanI don't know what's fastbus/asynchronous/synchronous mode :/
19:56:28funmanonly saw it mentioned in the control register of cp15
19:59:30n1sSo, an initial experiment on the gigabeast yields some interesting results, writing to CLKCTL_MPCTL to change the clock seems to work, ticks seem to be directly coupled to this clock so if i lower the clock a tick takes proportionately longer time, if the disk spins down (and powers off) disk access will hang the system when the clock is lowered
20:00
20:00:52Domonokyn1s: so we would need to decouple the tick from the clock, either via a seoerate timer/counter if available, or via software..

23:11:32 Quit DerDome ("Leaving.")
23:11:52BigBambiand what do you mean any release?
23:12:00n1swhy is 2.2MB wrong?
23:12:10BigBambiThat looks fine to me
23:12:14dead3roh
23:12:19dead3rit's not unzipping
23:12:20dead3rthen
23:12:31n1sdead3r: are you on a mac?
23:12:40dead3ryeah
23:12:43gevaertsunzips fine here
23:12:47dead3rdo i need a 3rd party zip?
23:13:00BigBambimac OS X is a bit braindead on unzipping
23:13:11n1sdead3r: the dir in the zip starts with a dot so the friendly unzipping app hides it :)
23:13:11BigBambiuse rbutil, it is much easier
23:13:18linuxstbNot OS X, just Finder. The command-line "unzip" program works fine.
23:13:35BigBambilinuxstb: Sorry, yes
23:14:41linuxstbdead3r: We recommend this - http://www.rockbox.org/twiki/bin/view/Main/RockboxUtility

23:21:06dead3ri'm guessing the support for it is still in development?
23:21:32scorche|shno one is working on it at the moment
23:21:34BigBambiNot really
23:21:48BigBambidead3r: It is encrypted and new undocumented hardware
23:22:30BigBambiBaring a major unexpected and remarkably unlikely breakthrough, you won't see it for a long long long long time, if ever
23:22:34dead3roh i see
23:22:39BigBambiMy money is on never personally
23:23:08dead3rbrings to mind the PSP
23:23:18dead3rtoo bad
23:25:14*bluebrother likes the "unsupported player variant" detection :)
23:25:37linuxstbbluebrother: Doesn't rbutil say what it's detected?
23:26:50bluebrotherit says that it detected a player, but the detected player is unsupported
23:27:48dead3ri think mine's a 6th gen, no?
23:28:09bluebrotherhmm, how are stacks handled in the sim? It seems that trying to solve an empty sudoku hangs in an endless (?) loop until stkov
23:28:14bluebrotherbut in the sim it works fine.
23:28:34BigBambidead3r: yes, that is what a classic is
23:29:17funmanbluebrother: It probably uses the host' stack
23:29:28linuxstbIt does.
23:29:29funmannot sure if it's given by linker or operating system
23:29:52bluebrotheranyone ever tried using the same stack on the sim?
23:30:13funmanbluebrother: try "ulimit -s yourstacklimit"

23:32:53lwizardli'm having trouble installing rockbox on my black 30gb ipod video. using the windows installer
23:32:58 Quit kushal_12_27_200 ("Leaving")
23:33:42bluebrotherso ... how does this trouble look like?
23:34:10lwizardlin the installer it fails the complete install
23:34:48 Quit bertrik ("Leaving")
23:34:56bluebrotherand I bet it fails with *drumrolls* an error message!
23:35:09lwizardlyeah
23:35:25bluebrotherso, you're expecting me to guess your error message?
23:35:38lwizardlfailed to install bootloader
23:36:03bluebrotherok. How did you configure? Did you use the autodetection button?
23:36:38lwizardlyes it detected the player but not the type
23:36:55bluebrotherthe player but not the type?
23:37:05bluebrotherso what did it detect?
23:37:13lwizardlit found its mount point, and the opened the apple tab but didn't highlight the model
23:37:27 Quit n1s ()
23:37:35bluebrotherdid you do a manual install / a previous install?
23:37:40lwizardlno
23:38:21funmancan you try on a USB1.1 connection ?
23:38:36lwizardlall my ports on the machine are 2.0
23:38:36bluebrotherdo you have a hub between PC and player?
23:38:52lwizardlbluebrother: nope direct to the ports on the back of the pc
23:38:52 Quit {phoenix} (Remote closed the connection)
23:39:06bluebrothercan you try a different cable?
23:39:17lwizardlnope only cable i have
23:39:57bluebrotherwell, it looks like ipodpatcher isn't recognizing the Ipod. There have been reports for this happening due to bad cables or usb ports.
23:40:00funmansay 'abracadabra' and try again ;)
23:40:13lwizardltrying different ports
23:40:26 Quit petur ("*plop*")
23:40:27bluebrotherso you could try to use a different usb port. If that fails try to borrow a cable somewhere
23:40:38bluebrotheror try a different computer.
23:40:39lwizardlthat worked
23:40:52lwizardlport next to the nic cable worked

23:48:59lwizardlbut i'm not seeing the instructions on how to do it. can someone point me in the direction
23:49:44bluebrotherhttp://www.rockbox.org/wiki/WpsGallery
23:51:09lwizardlyeah i'm looking at that page. when i select my ipod version it just takes me to a place to download various themes
23:51:27lwizardlbut does not explain on how to install them
23:53:14bluebrotherjust unzip the files to the player
23:53:30lwizardlto the root?
23:54:06bluebrotherand "rockbox theme install" is a good term for asking google ...
23:54:17bluebrotheryes, to the root. If that doesn't work the theme is not packaged properly
