00:01:24linuxstbmarkun: So you received the gigabeat source this morning?

00:02:23linuxstbIt sounds incomplete. Does it contain scripts to rebuild and install the gpl software that runs on your device?
00:02:33markunonly this file maybe:
00:02:44markunNo, it doesn't
00:03:39markunonly the tar balls of the open source software used in the gigabeat

00:03:57linuxstbTo quote section 3 of the GPL: "The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable."
00:04:46linuxstbIn this case, "installation" would seem to have to mean installation on a real device.
00:05:26markunpreglow told me I should ask for more, but I don't really feel like bothering them all the time

00:06:24]RowaN[guys where can i get one of those dual power+usb leads for h1x0 iriver series? there used to be some on ebay but i dont see them anymore
00:06:40linuxstbI understand how you feel, but they don't seem to be fulfilling their gpl obligations. It could be worth an email to the FSF to get their opinion about whether you are entitled to more or not.
00:06:40]RowaN[i managed to lose my big-ass wall charger over xmas some how =[
00:07:56linuxstbBut Toshiba could be in a tricky situation if installation of a modified kernel requires the user to encrypt the kernel using a secret key.
00:08:32webguest46hi, is it possible in rockbox to tell when the battey is full charged?
00:08:46webguest46on h3x0
00:09:37linuxstbI don't think that's been implemented yet. But others may know for sure.

00:25:39Mongeyyes, dissapointing
00:25:51BHSPitMonkeythe last time i tried, the build was broken and i set the interest aside

01:06:42linuxstbThat's a strange error. Did you re-run configure after fixing your PATH? You should probably delete your build directory and start again.

01:10:23BHSPitMonkeyoh, and when i try to build a simulator for nano it goes into the most horrible loop ever
01:11:18linuxstbYou could try downloading a fresh copy of rockbox-devel - it sounds as if something's wrong with your copy.
01:11:38linuxstbAre you doing all this under Linux?
01:11:56BHSPitMonkeycvs, updated not long ago
01:12:26linuxstbHave you tried building the bootloader?
01:12:48lokkiLinusN: i try to enable peakmeter for the remote (h-120) it's all fine, except for the size of it... do you know where i have to look in the code?
01:14:05BHSPitMonkeyshould I?
01:15:11linuxstbIt won't fix your problems building Rockbox, but you will have to install the bootloader if you want to try running it.

01:16:05LinusNlokki: the width?
01:16:07BHSPitMonkeyalso why I really want ipodloader2 to support rockbox sometime :P

01:16:20lokkiLinusN: yes exactly
01:16:31linuxstbBHSPitLappy: Feel free to add it :)
01:17:05*BHSPitMonkey != genious
01:17:27lokkiLinusN: i see there is a variable width, i thought it depends on LCD_WIDTH, changing that to LCD_REMOTE_WIDTH doesn't help however
01:17:32LinusNlokki: gwps-common,c
01:17:38linuxstbYou just need to copy the function load_rockbox() from bootloader/ipod.c into the ipodlinux2 bootloader
01:17:42BHSPitMonkeyshould I try just cvs'sing the normal rockbox branch?
01:17:57lokkiLinusN: ok...thanks a lot i will look there
01:18:10BHSPitMonkeyand i will definitely look into that then...
01:18:10linuxstbBHSPitLappy: What do you mean? There is only one rockbox branch.
01:18:18LinusNlokki: replace LCD_WIDTH with display->width
01:18:36BHSPitMonkeylinuxstb: type? collection? whatever, in opposition to rockbox-devel
01:19:17lokkiLinusN: in peakmeter.c you mean?
01:19:38linuxstbBHSPitLappy: It's the same thing. But if I was you, I would try starting again with a clean checkout of rockbox-devel
01:19:40lokkiin gwps-common
01:19:52lostlogicheh, same problem happened when I made the A-B repeat patch for swcodec
01:20:05LinusNi guess peakmeter.c needs to adapt to the "display" concept
01:20:10lostlogicLinusN: a-b repeat patch could use merging for swcodec ;)
01:20:28LinusNlostlogic: :-)
01:20:59LinusNlostlogic: do you think we need to move some buttons around?
01:21:45 Quit Kyl3 ("( :: NoNameScript 3.81 :: )")
01:22:04BHSPitMonkeylinuxstb: also, i apologize for my limited familiarity with rockbox so far, but does rockbox build to a single file firmware? is there a filesystem?
01:22:09lostlogicLinusN: I believe at least one person who is using the patch moved them around. I dunno −− getting to settings would have to be inconsistent to deal with it currently.
01:22:22lokkithat was me
01:22:27lostlogicLinusN: either in rec or WPS there's going to be an inconsistency unless we use a long press for the settings.
01:23:15lokkii moved the menu button to rec, inconsistency in the rec screen
01:23:19 Quit BHSPitLappy2 (Connection timed out)
01:23:31lostlogicLinusN: do you think that there will be a record from wps function coming?
01:23:51LinusNrecord from wps? hardly
01:23:57linuxstbBHSPitLappy: There is a sort-of filesystem - typing "make zip" after "make" will create a file which contains rockbox.ipod (the main firmware binary), plus a .rockbox directory that contains fonts, plugins, codecs, themes etc
01:24:20lostlogicLinusN: then I'm inclined to leave it as the patch is and let people figure out that rec does A-B in WPS screen.
01:24:27linuxstbTo install, just then just type "unzip -d /mnt/ipod/"
01:24:46lostlogicbecause having a short press for the menu is a Good Thing
01:24:48 Quit Mark_ (Read error: 104 (Connection reset by peer))
01:25:03LinusNlostlogic: me too, but it sure feels awkward to not use the A/B button for the A/B function :-)
01:25:08lostlogicand consistency is so often lacking in other firmware products, but _not_ in rockbox
01:25:30linuxstbBHSPitLappy: But there is no partitioning of the type needed for ipodlinux - all files are stored on the FAT32 partition.
01:25:34LinusNrockbox is pretty inconsistent in many areas, but the menu button is the same everywhere
01:25:45BHSPitMonkeylinuxstb: i see
01:26:01lostlogichmm... I've only really noticed inconsistency in the plugins compared to the main OS
01:27:10webguest46lostlogic: thanks for your answer, i'm glad someone is working on it
01:28:58lostlogicwebguest46: It's not really a big difference, the functionality isn't likely to change, just the display.
01:29:50lostlogicLinusN: how much have you done with the PCF50606? Have you ever seen it get into a state other than the state it 'should be' left in by the iRiver firmware? I think I got it into such a state, which says to me we should set it's charge control registers on boot up rather than assuming they are set.
01:30:39LinusNlostlogic: we should set it the way we want to
01:31:09LinusNfor example, the exton wakeup can sometimes be disabled
01:31:57lostlogicLinusN: yeah, it actually has a pretty nice featureset that we are ignoring. I'll work through it more when I get my replacement H340.
01:32:28webguest46lostlogic: yes, i know the charging is done in hardware, but it would be good to know when the battery is full. many people say that it is bad to keep the charger plugged in when the battery is full.
01:33:57lostlogicwebguest46: As far as I can tell that's a falacy, the charger stops being in charge mode when it reaches full, I need to verify that it is not charging at all in this mode though.
01:34:36 Quit Kohlrabi ("Leaving")
01:34:41LinusNlostlogic: still, it will probably trickle charge
01:34:45lostlogicwebguest46: if necessary, I'll turn on the charge control feature of rockbox to have the software deactivate the charge completely when the battery is full.
01:34:59lostlogicLinusN: that would be really dumb on LiPoly, but you're probably right.
01:38:33LinusNseems the charger automatically switches off the charging after the fast-charge is done
01:38:51LinusNthen you have to select either trickle or switch mode afterwards
01:39:47LinusNhmmm, switch mode wasn't what i thought it was
01:39:56lostlogicthe MBCC registers during charge were 3F, 00 and 3A and the status was 5D or 1D depending on what part of the charge cycle it was in

01:45:45lokkibut the peakmeter is still to big for the remote...
01:45:50lokkiim to dumb for this
01:46:34lostlogiclokki: you'll get it −− the code in peakmeter.c is probably called for each screen by the gwps-common.c, so you should only handle one screen in any given call to peakmeter.c
01:46:40lostlogicdoes that make sense for what you are working on?
01:47:03lostlogicyou probably need to add a 'struct screen * display' parameter to the peakmeter.c calls or some such

01:51:10lostlogiclokki: then you'll call screen->function instead of lcd_function inside the peak_meter_draw function

10:34:11JancoBger: I got the simulator working now. Strangely enough the color bitmaps appear to be correct on the real target (H340) but have different colors in the simulator (B instead of R, G instead of B, etc.). Will have a look into that tonight, probably.

10:38:37JancoLinusN: Probably, but since the colors are right on the real target, shouldn't this be corrected by the simulator? Or do I have to take this into account in my code?
10:38:39preglowsure, just gimme an addy
10:39:07LinusNJanco: the sim is little endian, the target is big, and your bmp reader probably gets it wrong
10:39:36B4gderJanco: if your code is correct (and the sim does right), the sim and target should of course look the same
10:43:39JancoAs I said, I have not a lot of experience with this kind of programming, so I suppose my code is not correct. I suppose I do it wrong twice (reading and displaying), which makes it correct for the target, but not for the simulator. Will have to study this problem.
10:44:34B4gderyou run the sim on a x86 cpu, right?
10:46:37JancoAlso, I used my own internal representation for color bitmaps (nothing fancy). This might not be what the simulator expects. Has a rockbox color bitmap format been defined (as was done for monchrome)?
10:47:11B4gderthe framebuffer use the target format
10:47:16JancoB4gder, that's correct (cygwin under XP).
10:47:29B4gderand we use bitmaps in the same format as the framebuffer wants them

10:50:12JancoI don't have time now, I will look into the matter this evening.
10:52:07JancoBut I must say, it looks nice with colors. But I expect stills lots of problems. Part of it is the wps format.
10:53:13JancoI think it could be revised to admit absolute position (in pixels) of strings in any font.
10:53:35B4gderyes indeed
10:53:56LinusNeither we extend it so it can handle both b/w and color bitmaps, or we store the b/w bitmaps in color format
10:54:08B4gderI vote the for latter
10:54:17LinusNme too

10:58:01JancoI don't think either is necessary. My reader detects the bitmap depth and stores it with the image. The screen refresh functions (don't remember the name) then calls a new function with the colr_depth as a parameter.
10:58:34B4gderfair enough!

13:58:27preglowamiconn: yes, exactly
13:58:47preglowpetur: how can it be better?
13:59:05preglowpetur: in our case it will be, since we don't use all the 24 bits, but if we did, the adc can't gain the signal any better than we can

14:06:23peturyou mean the tow combined or below each other?
14:06:36preglowone slider for each
14:06:43preglowi think that's cumbersome
14:07:03preglowi'd rather have one option for gain, and an indicator telling me if i'm gaining digitally
14:07:10preglowbecause one slider is better than two
14:07:19pregloweasier, more convenient
14:07:38 Join eli_sherer [0] (
14:07:56peturso just add an indicator to show if the current gain setting is analog or digital...
14:08:14markunAnd the digital gain will not be used as long as analog gain is still possible
14:08:33preglowi think this matter should be resolved in the manual anyway
14:09:13preglowpersonally i think there should be a limit where the analogue gain limit is
14:09:34markunpetur: maybe you can display the value after which the digital gain will kick in
14:09:39preglow24db should be enough for everyone!!
14:09:51preglowbut no
14:09:59preglowan indicator when you're doing digital gain would be nice

14:18:45Zoricyeah. Thats what I've been using on windows. Now that I've begun using linux I find myself without that...
14:19:12B4gderand... that's also why I've never played with replaygain
14:19:20crwli don't think there's a tool to add replaygain tags to mp3 files in linux
14:19:23markunyou can use foobar with wine if you really want to
14:19:34Xerionjust google for replaygain + linux :P
14:19:36B4gderI don't use wine

14:20:16markun't store the info in tags
14:20:21Zoricand that script can scan files and add info?
14:20:31markunIt now stores the undo info in apev2 tags
14:20:43Xeriondon't know, only googled it ;)
14:21:05crwlXerion, it's an ugly hack, and it only enables amarok to play back replaygained files correctly
14:21:06Zoricyeah read something about it on the wikipedia page i think
14:21:18Zoriccrwl: ok thanks
14:21:21crwllast time i checked, that script didn't add the replaygain info anywhere

14:58:09preglowcolours refused to work
14:58:19markunah, the TERM thing..
14:58:28alphakillerbut have you heard someone installing the bootloader on windows ?
14:58:29preglowand saving was tedious, since vim all the time reminded me it couldn't write a backup file, this despite me having turned off backup
14:59:03linuxstbalphakiller: No. preglow tried and failed. But I have an idea that may work - I just need to find the time to reboot into Windows and test it out.
14:59:05markunI can't remember having these problems.
14:59:13markunMaybe god hates you, not bsd..
14:59:53linuxstbThe problem is that the ipod's firmware is stored in a small (40MB-80MB) partition marked as "empty". Cygwin doesn't give you access to this device as a normal /dev/sd?? device

15:01:22linuxstbI had the same problem on Mac OS X, but solved it by writing a small utility that accessed the "whole disk" device instead of the devices created for the individual partitions - /dev/disk1 on the Mac.
15:01:31aliaskonce you start using the firmware you will notice things that you might like fixed.
15:01:53markunalphakiller: port the flite text-to-speech program to rockbox
15:02:14linuxstbI haven't tested that program on cygwin, but I think it should work -
15:02:31markunalphakiller: or the speex codec
15:02:41linuxstbAlso, the ipod video needs slightly different instructions for installing the bootloader - I'll try and update the Wiki.
15:03:17linuxstb(a firmware image that runs on the Broadcom chip needs to be in the boot partition, along with the normal ipod firmware)
15:03:20alphakillerI'm not going to port a high level thing :P
15:03:32alphakillermy target around here, is to hack arm
15:03:44alphakilleran existing arm platform
15:04:25linuxstbThe ipod has two ARM cores - that could be an interesting aspect to explore. Currently, Rockbox puts the COP (coprocessor) to sleep and only uses the main CPU.
15:04:45alphakillerhmm ... like psp :P
15:04:54alphakillerpsp has two mips r4000 processors :D
15:04:59alphakillerone main cpu and another as cop
15:05:04linuxstbYou'll be right at home then...
15:05:22alphakillerhehehe ...
15:05:33alphakillerplaystation 2 has 5 or 6 cops
15:06:19markunany idea yet what the cop should do? It can only run at speed <= the main CPU, right?
15:06:20preglowyeah, but they're not cpus
15:06:29preglowthey're specialised units
15:06:41preglowyou can scale the cope somewhat
15:06:42alphakillermarkun: decoding ??
15:06:47preglowand i'm planning on using it for decoding and dsp
15:06:54preglowand fiq handling
15:06:59linuxstbI believe the cop can run at either 100% or 50% of the main CPU's speed.
15:07:12linuxstb(or 0% if it's sleeping)
15:07:32alphakilleryou just assign task for the cop and he will do markun
15:07:39alphakillerI just dunno how these tasks are assigned to the cop
15:07:39markunwhy not use the main CPU for decoding and the COP at 50% for some less intensive tasks?
15:07:53alphakillerin the mips based architecture you send like "packages" for the coprocessors
15:08:08alphakillerand you don't need to stop the current execution on the main processor
15:08:14alphakillerto send such data
15:08:19alphakilleryou just send the packages
15:08:23alphakillerand continue processing
15:08:39alphakillerno no ..

15:21:17markunI thought you were talking about output quality..
15:21:17lostlogicmarkun: realistically though, the gigabeat port should be easier than the iPod port since it has just one higher clocked ARM rather than having the complexity of controlling two.
15:21:49markunAnd we have the documentation

15:23:08alphakillerhaving two cpus you have the advantage of having less OS code that does threading running .. that's where you lose performance
15:23:42preglowwe'll need more os code for threading
15:23:44preglowfor two cores
15:23:51lostlogicalphakiller: not with a round robin cooperative scheduler like rockbox
15:23:53preglowahh, right
15:23:54preglowlike that
15:23:55preglowforget me
15:24:06preglowlostlogic: he meant less time spent in context switch
15:24:38lostlogicah, right. yeah, having one core that can be dedicated to the single highest CPU task, on one thread is definitely beneficial.
15:25:08lostlogicpreglow: I would think that what I just said is the better way to deal with it than having the PCM output and codec on the COP...
15:25:10alphakillerheheh, Apple Engineers are the best around there :P
15:25:41alphakillerI have had lots of small devices around there
15:25:51alphakillerthe bests I had were from Apple
15:25:56LinusNi wouldn't want a transparent scheduling between the two cpu's
15:26:21preglowLinusN: you wont have it either
15:26:33preglowthe cop will run a fixed set of threads
15:26:36preglowperhaps only one
15:26:40alphakillerthat's what I said
15:26:45LinusNthen i'm with you
15:26:47 Nick elisherer is now known as eli_sherer (
15:26:55preglowif we didn't do this, we'd have cache issues
15:26:59pregloweach core has its own cache
15:27:04preglowand the bus isn't snooped
15:27:15alphakillerwell, that's what I would like to play with :D
15:27:21preglowthen hooray!
15:27:28preglowi certainly wont stop you
15:27:30alphakillerdevelop the "driver" to send stuff to the cop
15:27:32amiconnImho the scheduler for the COP should be easy. What's more complicated is the cache coherency, as we surely need to pass data between both cores
15:27:42preglowamiconn: not much data, i'd think
15:27:44LinusNand the thread synchronization
15:27:47preglowamiconn: and for what little there is, iram is good
15:28:00alphakillermy idea is not having a scheduler on the cop
15:28:14alphakillerthe cop just will run a thread
15:28:20alphakillerdetermined and packed by the cpu
15:29:11markunToo bad the speeds can't be canged independantly..
15:29:12alphakillerso a main task sends a thread to the cop
15:29:12alphakillerthat's the idea
15:29:12alphakillerthat's where you reduce the overhead of context swithc
15:29:12DBUGEnqueued KICK alphakiller
15:29:36alphakillermy idea is this:
15:30:45alphakillerMain Task −−> ask for cop −−> turns it on what speed it would likes to −−> package thread −−> send packet to cop −−> do another thread from the task in parallel on the cpu, while cop works on another thread
15:30:57markunHow does such a mailbox work btw? You can write something to it and the other CPU gets an interrupt?
15:31:25alphakillerI've never worked with mips before
15:31:38markunwith arm.. right?
15:31:41alphakillerI dunno even the global memory is shared between the two processors
15:32:33preglowmarkun: don't really know, you write data somewhere, then the cop gets an interrupt
15:32:34alphakillerif we have the global memory shared between them, we could stablish a global pointer where cop tasks will write to
15:32:42preglowalphakiller: cache issues
15:32:54preglowalphakiller: we'd have to flush the cache before we did that
15:33:01preglowalphakiller: it's better to use the iram, since that isn't cached
15:33:13alphakillerhmm ..
15:33:38alphakilleryeah, but my idea is to have an unified global point down somewhere
15:33:41alphakillerirqs are pretty slow :P
15:33:48preglowwe don't need to use irq
15:34:30markunit's faster to check the memory location from time to time?
15:34:32preglowthe cop can be stuck in a loop, reading a variable from iram to see if it should wake, and then the cpu can send it to sleep, set the variable whenever it needs to, then wake the cop again, so it can work
15:34:47preglowsee if it should work, that should be
15:34:59preglowthe cpu can freeze the cop whenever it wants to, we should use that
15:35:07eli_shererprobably gonna cause the use of "wait" and "signal" if there is a mutual resources...
15:35:19alphakillerhmm .. and rather easy to do that :D
15:35:56markunalphakiller: well, what are you waiting for then, get to work :)
15:35:59alphakillerbut it should have a data flux from the cop to the cpu and vice-versa
15:36:47alphakillerand something to input routines ...
15:37:01alphakillermy idea is to do something like:
15:37:12alphakillerhook_CopCode(pointer function)
15:37:25alphakillerunhook_CopCode(pointer function)
15:37:54preglowjust keep in mind that the cpu and cop can't share data via regular memory
15:38:11preglowthat will require us to flush the cache all the time, which isn't very wise
15:38:34alphakillerso we need a way to copy thread code somehow
15:38:45LinusNalphakiller: unhook?
15:38:52alphakillerand store it in a fixed address
15:39:02alphakillerLinusN: link and unlink code
15:39:09preglowyou don't need to copy any thread code
15:39:14LinusNyes, but why unlink?
15:39:15preglowjust load it, have the cop flush its cache, then execute
15:39:52LinusNand what is the pointer in the unlink function?
15:40:14alphakilleroh .. forget heheh
15:40:18alphakillerthe pointer()
15:40:22alphakillerit's void :D
15:40:29alphakillerunhook(void) :P
15:40:34LinusNok, then i'm with you
15:40:46alphakillerand the pointer it self is the flag
15:40:53alphakillerunhook sets pointer to null
15:41:08alphakillerand hook setspointer to something
15:41:09LinusNok, so we could just have one function: link(ptr)
15:41:09alphakillerwe just have a loop
15:41:21LinusNand link(NULL) to unlink
15:41:22 Quit ashridah ("Leaving")
15:41:36alphakillerand then loop forever
15:41:45alphakillerif pointer null, do nothing
15:41:50alphakillerelse, call function :D
15:42:16LinusNperhaps cop_run(ptr);
15:42:22alphakilleryeah :P
15:42:23alphakillermore pretty
15:42:39alphakillerpreglow ?
15:42:44LinusNand a few others, like cop_put_msg(ptr) etc
15:42:59alphakillerwe are discussing cop issues :P
15:43:09preglowsure, i follow you
15:43:14alphakillerI was waiting for your point :D
15:43:22LinusNcop_run(NULL) <−− cop killer ;-)
15:43:31alphakilleryeah :D
15:43:32preglowLinusN: no, it'll just reset :)
15:43:52preglowthat's where the reset vector is, heh
15:43:57LinusN- there she is, set for "stun"
15:44:13alphakillerso, it's rather easy having the cop in a loop
15:44:15preglowi wonder what the cpu will do when the cop goes in for reset...
15:44:30alphakillernothing :P
15:44:32preglowbut yeah, just a loop waiting for a flag on where to go
15:44:43preglowand when the cpu knows the cop is in this loop, it also tells it to sleep
15:44:47preglowso we don't waste too much battery
15:44:51alphakillerI prefer the loop idea :D
15:44:54alphakillerand sleep
15:45:03alphakillerso we would have 2 procedures:
15:45:04alphakillerwake up
15:45:07LinusNloop: sleep;jmp loop;
15:45:08alphakillerand assign task

16:07:19preglowcurrently, it's 100mbit/s
16:07:25preglowif you just mean in the general case

16:09:49aliaskTo the general internet?
16:10:02alphakillerpreglow: saw the sample code?
16:10:08alphakillerlinusN ?
16:10:46alphakillerso we just have a permanent "nanokernel" running on the cop
16:10:51alphakillerthat calls the thread
16:10:56alphakillerotherwise, sleep
16:11:27alphakillerthen, the cpu awakes the COP before assigning a new task
16:12:33alphakillerthis is the simple part I guess ... the complex part it would be develop an API to share data

18:24:30preglowadding layer 2 support to a layer 3 decoder is not very hard at all
18:24:36 Quit einhirn ("Miranda IM! Smaller, Faster, Easier.")
18:24:50markunsrs wow sounded terrible with my oggs on my H120, but maybe that got fixed in the newer firmwares.
18:25:49preglowsrs tends to amplify encoding artifacts for me
18:25:53saa[b_r]idermp2 as in layer II?
18:27:21markunsaa[b_r]ider: yes
18:30:52saa[b_r]iderlinuxstb: why are you interested in MP2 files?
18:31:18preglowbecause there is tons of mp2 around?
18:31:26linuxstbBecause I've been archiving digital radio broadcasts in their original MP2 format for the past 3-4 years.
18:31:29preglowdab radio, for example, is mp2
18:31:48linuxstbAnd I need some way to listen to them...
18:32:56linuxstbI would also like to be able to recommend DAPs to others that can natively play MP2 files. Rockbox devices are the only ones I'm aware of. IIRC, the Archos firmware would only play them if you renamed them to .mp3
18:33:14lostlogiclinuxstb: what, and you don't want to transcode them:):):)
18:33:17saa[b_r]ideraha, wasn't aware that it was the common format for radio broadcasts
18:33:47linuxstblostlogic: What do you think? :)
18:33:54saa[b_r]iderthe iRiver *might* play them...
18:34:09linuxstbAt least not the h1x0
18:36:00linuxstbsaa[b_r]ider: In Europe, almost all digital broadcasts (both TV and Radio) use MP2 audio. In the USA, the broadcast standard is AC3. I don't know about the rest of the world.
18:36:04saa[b_r]iderok, I found my MP2s, I;ll try
18:36:12preglowbroadcast ac3?
18:36:16preglowwhat bitrate?
18:36:22linuxstbVaries from 128kbps upwards.
18:36:35preglowi imagine it doesn't sound very good
18:36:41preglowac3 isn't a very complicated codec
18:37:16linuxstbIt's not too bad. No worse than 128kbps MP2.
18:37:44linuxstbBut generally, I think it's 384kbps.
18:37:54linuxstb(for HDTV broadcasts)
18:38:08preglowahh, t
18:38:17linuxstbYep, TV.
18:38:19preglow128 kbps mp2 is something different agin
18:38:29preglowit isn't a transform codec, so doesn't sound so bad when mangled
18:39:20saa[b_r]iderok, H300 doesn't display MP2 files, I'll try to rename it to MP3 and see if it plays
18:40:20preglowit doesn't play them
18:40:22preglowdon't worry
18:40:37preglowi bet they're using the motorola codec, and that only supports mp3
18:40:56saa[b_r]ideryou're right... just wanted to reconfirm :)
18:42:55saa[b_r]iderany idea if iPodlinux supports unicode?
18:43:09linuxstbNo idea.

18:46:51preglowand can probably be made faster
18:46:57markunmpeg2+ac3.. sounds like we're making a micro dvd player :)
18:47:05preglowconsidering the small amount of work i did to make it as fast as it is today

18:55:01linuxstbIt all depends on the quality of the encoder I think.
18:55:06mirak_with 300kbit for xvid image is perfect, there is no artifacts

21:16:02alphakillerthe important thing now is how I can make both cores work on your kernel
21:16:20alphakillerI might use that "nanokernel" idea, to put it on the other core, and let it in piece :D
21:16:34alphakillerlinuxstb: can i deattach ipod?
21:16:35alphakillerand test ?
21:16:39alphakillerit's written
21:16:47linuxstbYou should also get a copy of all the ipodlinux source you can find - that will help with the low-level stuff.
21:17:28linuxstbalphakiller: Yes - it should display some logos (but they are corrupt - an easy bug that I haven't fixed yet) and then load the Apple firmware.
21:17:54alphakillerhmm ... you killed my iPod :@
21:18:02alphakillerit turns on, then off
21:18:58linuxstbOK... Try plugging it back into your PC and seeing what "diskdump /dev/sdb" tells you.
21:19:38alphakillerit can read my ipod
21:19:43linuxstbAlso, can you still see the normal FAT32 partition when you plug it in?
21:20:39alphakillerit locked up my explorer
21:20:43alphakilleron windows ..
21:20:50linuxstbAh windows...
21:21:03alphakillerbut the partition table isn't changed
21:21:16linuxstbI've heard people talk about "ipodservice.exe", and having to restart it sometimes.
21:21:39linuxstbYou could try restoring "bootpartition.bin" back
21:21:47alphakillerthat's what I'm trying to do

21:24:02linuxstbYou're the first person to try this on Windows....
21:24:20alphakillerwell, seems it was locking my windows, coz I just restored the FAT32 FS
21:24:29alphakillersomething overwrote that on our image
21:24:40linuxstbIf you do end up with an unusable ipod, you can download the "ipod restorer" from the Apple website, and restore your ipod using that.
21:24:41alphakillermy guess

21:30:10linuxstbI have a similar Dell at work
21:30:21linuxstbMust have been the last models with usb 1.1
21:30:41ender`in 2003 1.1 was still common - and you usually got 2 2.0 ports at the back, plus 1-2 1.1 ports in front, and sometimes additional 2 1.1 ports at the back

22:32:09linuxstbkkurbjun: I haven't looked at your patch, but have you made more use of IRAM?
22:32:46linuxstbI don't think rockboy currently uses very much IRAM - big speed improvements could possibly be gained in that direction.
22:33:28kkurbjunlinuxstb: I don't know how to use IRAM .. its that some code cache? and do you have an example in rockbox that you can point to that uses it?
22:34:16Learkkurbjun: see codecs
22:34:32kkurbjunok, I'll look at that
22:34:37Learassuming it works for plugins, that is... :)
22:35:50linuxstbYes, it works the same in codecs and plugins
22:36:18linuxstbIRAM is the fast 96KB of internal memory on the coldfire. Putting data in iram means it can be accessed a lot faster than from the slow SDRAM.
22:36:28Learbut what if you try to run a plugin that needs iram when playing music?
22:36:38linuxstb48KB of IRAM is used by core Rockbox, 48KB can be used by a codec or plugin.
22:36:39kkurbjunahh, so data cache
22:36:53Bagdernot cache, just fast ram
22:37:01linuxstbrockboy stops playback anyway. I'm not sure how the details work, but I'm sure they do.
22:37:01Bagderor rather less slow ;-)
22:37:25Bagderrockbox stops playback because it nicks the buffer
