04:12:11krazykitno
04:12:14eliaspok
04:12:53eliasphmm... then i'll have to find a script which overrides these crazy vfat filename restrictions by renaming the files.. ;-(
04:13:42Unhelpfuleliasp: utilities for generating FS-safe filenames from tags are extremely common
04:14:28eliaspUnhelpful: i'm actually syncing my files using rsync... so let's see how i can integrate such a script into this proces...
04:15:41Unhelpfuleliasp: well, the easiest way would be to sync them after giving them names that are safe...
04:16:16eliaspUnhelpful: i sync them directly from my mediaserver, so this would involve copying them first to a temporary location and then onto the device...
04:16:25eliaspok, what i could do... create safe named symlinks
04:16:41eliaspthat's probably the best way
04:16:46Unhelpful...or rename the files with safe names on your server?
04:16:50eliaspsymlinks with safe names in a temporary location...
04:17:11eliaspUnhelpful: nope... just because of this crappy vfat i will not rename all my files on my server
04:18:36Unhelpfulit's by far the lowest-maintenance solution. and "crappy" though it may be vfat is the most widely-supported filesystem, unless you count feature-incomplete ext2 support on windows as making ext3 "widely supported"

04:19:58eliaspbut i think i'm fine with the symlink+script solution
04:20:12Unhelpfuleliasp: your choice then, have fun. i don't know anything that will help you with your symlinks. :)

05:49:34Unhelpfulhrm, to what degree is a previously-used codec "reused"? can i be certain that the codec's static data will be freshly copied from the buffer or the disk before the start of each file? if so, i think i see a way to get best-possible performance out of ape for each profile without greatly complicating its startup...
05:51:33 Join komputes [0] (~komputes@ubuntu/member/komputes)
05:56:00Unhelpfulinstead of having a real malloc for iram, do something like this: fill available iram with table, but calculate a table size for each profile based on the space that would remain after statically allocating that profile's buffers from the end of iram. make a table with the compare instructions for each table size. on codec init, copy the appropriate instructions from the table to the start of udiv32_arm (which can easily be ordered to put
05:56:00Unhelpful this compare first), and allocate filter buffers starting from the end of iram, aliasing the reciprocal table. if we make sure the end-of-iram address is available at link time, these can even be declared static and initialized in much the same way as they are now.

08:48:39amiconnUnhelpful: Reloading from disk would defeat the point of buffering codecs in the first place. And since buffering it multiple times would be a waste, reuse was implemented. Nothing gets reloaded, the codec asks the core whether there is another track to decode
08:49:42Unhelpfulamiconn: ok... so it will need to be able to re-initialize the reciprocal table. and udiv32 and its table will need to be the very last thing in iram... maybe add a section for that purpose?
08:49:45amiconnI think that filling the reciprocal table programmatically (doing actual divisions) wouldn't take long

08:55:49Unhelpfulright... the bulk of the value of the table is up front, and the only reason to maximize it is to get whatever small gain is possible out of the available space. :)
08:56:42Unhelpfulthinking that way, it's probably not worth doing dynamic table allocation... just have enough static buffer in iram for modes that might possibly decode in realtime, and use the rest for the table

09:00:20Unhelpfuli note that the speex codec has some saturate operations in it also. is it important for the codec that saturate be to -32767/+32767, rather than full 16-bit range?

09:18:01*amiconn is puzzled by the weird behaviour of both his PP5022 targets which means he cannot get results for -c5000
09:18:15 Join TheSeven|Mobile [0] (~theseven@rockbox/developer/TheSeven)
09:18:56amiconnBoth the mini G2 and the c240 shut down due to low-bat at a point not even halfway through the file
09:19:22amiconnNo other target does this, even though PP5020 and PP5002 are slower
09:19:41Unhelpfulamiconn: can't you plug them in while testing?
09:19:53amiconnAnd after powering back up, the battery is nowhere near empty. It even happens when keeping the charger connected
09:20:47amiconnI suspect that somehow the low yield rate affects the powermanagement thread, but that would be really strange
09:20:49Unhelpfuloh :/ there's not a watchdog on them, is there? that's maybe not being serviced if the decoder is too long between yields on very very slow files?
09:21:03amiconnNo watchdog...

16:21:25Tornegevaerts: i'm wondering about adding a new USB state for "USB charger attached"
16:22:14TorneI think the best way to handle the charging stuff is to drive it from the usb stack, and only communicate simple "charge / don't charge" to the target code
16:22:26Tornebut then the target needs some way to signal to the usb stack that it's detected an actual charger.

16:48:38perfectdrugbtw is there an option to sort flyspray tasks by last commented, so that you can see which ones are active at the moment
16:48:57pixelmaTorne: I believe there was a small discussions about it just recently and this is still true on the Archos targets (with alarm functionality) and has to stay this way due to hardware initialisation or something
16:49:26pixelmaguess it's not true for other targets then
16:50:20TorneYes, possibly
16:50:25Tornethat's why I didn't just change the manual myself

16:59:18gevaertsTorne: oh, you don't want to combine it with "usb connected,500mA available"? Ok, then it can indeed go in the same state machine
16:59:29Tornei mean as an alternative to USB_POWERED
16:59:56Torneso instead of going from POWERED to INSERTED when it detects a host, it would go POWERED to CHARGER when it detects a charger (e.g. by D+/D- short)

17:41:57Torneooh, you can do 0 as well?
17:42:02TheSevenand i can detect if there is voltage present on the bus
17:42:14TheSevennot sure about detecting chargers (in terms of the usb charging spec)
17:42:27Torneto detect a standard USB charger you would need to know if D+ and D- were connected
17:42:32TheSevenbut I think we can assume that things that don't want us to enumerate are chargers
17:42:39Torneto detect an Apple one you have to use ADCs on D+/D-
17:42:52TorneTheSeven: no, that's not a safe assumption
17:43:19TorneI am intending to rework all this such that the user can choose whether to be safe or not, by changing the usb charging setting to yes/no/force

17:44:33TheSevenTorne: the hardware default on the nano (e.g. during boot) is 100mA

17:45:12Torne(for "no")
17:45:41Tornethe use case for setting usb charging to no is "i have my dap attached to my laptop to use it as a disk/whatever, and i don't want to drain the laptop's battery just to charge the dap's"
17:45:54Torneso if you have the ability to stop it drawing current entirely then that's desirable
17:45:54gevaertsTorne: http://www.rockbox.org/wiki/IRiverH1x0H3x0PortPins#PCF50606_GPO
17:46:05TheSevenTorne: I would be careful about that
17:46:32TheSevenwould it mean rockbox shutting down immediately if the battery is empty, before you have a chance to allow charging?
17:46:33Tornegevaerts: not very more helpful, but thanks :)
17:46:49TorneTheSeven: Hm, that's a good point
17:46:52TorneI hadn't thought of that one
17:46:58Tornebut that can probably be handled.
17:47:02TheSevenmaybe only go to 0mA if the batter is >10%
17:47:05gevaertsTorne: in that case, look at the schematics :)
17:47:23Tornehehe
17:47:31TorneTheSeven: Yeah, I'll make a note to consider that
17:47:49Tornefor now i'm trying to work out what the UI should be and what the usbstack <-> target interface should be
17:49:13Tornegevaerts: the schematics w ehave appear to have been written by linus as well
17:49:19Torneso they only say the same thing :)
17:50:34Torneaha, the datasheet for the battery charger will probably say
17:53:55Torneyeah it's switching VID1 on the lx2201 I think, so it should be selecting 0 vs 500, actually
17:54:40Torne..or maybe not.
17:54:46Torneahwell
17:55:01gevaertshm, 0 could mean different things depending on how things are connected
17:56:07gevaertsIf the thing can be powered without going through the battery, the 0 is only about charging and not about power usage

18:06:38pixelmaI thought there was some charger detection code for the PP Ipods back when we didn't have Rockbox USB though. It was there to make it stay in Rockbox and not reboot to the Apple OF but it was a bit buggy and caused Rockbox to hang in the USB screen on normal USB insertion
18:07:02pixelmawith some builds
18:08:10gevaertspixelma: that was actually more an abseense of host detection than a proper charger detection

18:10:34pixelmapossibly. Was it completely removed though?
18:10:44Torneno, we still have that facility
18:10:51Tornethta's the POWERED state
18:11:14Torne"5V is available but we have not received a bus reset yet"
18:11:48Torneit is not spec compliant to assume that just because you haven't got a bus reset command that the thing you are attached to is a charger :)
18:11:54 Quit Farthen (Quit: ChatZilla 0.9.86 [Firefox 3.6/20100115144158])
18:12:41TheSevenTorne: actually, it is true in 99% of the cases though
18:12:54TheSevenand there is no other way to detect a charger
18:13:04TheSeven(a cheap, non-spec-compliant one, like most are)
18:13:51TorneYes
18:14:06TorneThat doesn't mean it's not desirable to implement charger detection
18:14:43TorneMy intention is to change the setting to a tristate, off/on/force, where "force" will make exactly that assumption
18:14:50 Join wojtek111 [0] (~wojtek111@77-253-185-195.adsl.inetia.pl)
18:14:54Tornebut "on" will not, and will follow the spec
18:15:12Torne(so it will charge correctly from an active USB host, but not from a dumb USB charger that can't be positively identified)
18:15:20Tornethen "on" can be the default, beacuse it will be safe.
18:15:26TheSeven...so even "on" could lead to "bricked" because of empty battery conditions?
18:15:47wojtek111hi
18:15:52TorneTheSeven: er, how?
18:16:05wojtek111I have question but not about rb
18:16:12TheSevenbecause it will shut down before it has a chance to catch the reset if the battery is empty?
18:16:21TorneTheSeven: why would it shut down?
18:16:43Torneyou can draw 100mA as soon as you get +5V on Vcc
18:17:00TheSevenTorne: no, you can't neccessarily
18:17:11TheSevenonly if there is bus traffic
18:17:21TheSeven(if you really want to be spec-compliant)
18:17:38wojtek111does anybody know osx86 at insanelymac?
18:17:47TheSevenso you'd say that "on" will always draw 100mA, even if it can't detect the charger?
18:18:00TheSeventhat's roughly what the OFW is doing
18:18:02Torneaccording to USB-IF compliance stuff you can draw 100mA
18:18:20TheSevenTorne: not if the bus is asleep
18:18:21wojtek111whats is withe their irc channel?
18:18:39TorneTheSeven: nope
18:18:49TorneBattery powered peripherals are still allowed to draw 100mA while the bus is asleep
18:19:11TheSevenoh, you mean they changed that when they introduced that charging spec?
18:19:13wojtek111do you know how update ideneb 10.5.6 to 10.6?

18:19:39Tornewojtek111: this is off topic, ask somewhere else
18:20:13TorneHmm
18:20:32wojtek111i asked because can't find help anywhere, sorry
18:20:33Horschthm... Torne, is the DMA stuff in current builds yet?
18:20:38TorneHorscht: yes
18:20:46Tornealmost all buffering reads should be using DMA on pp502x
18:20:51Horschtsince when?
18:20:55Tornea week or so?
18:21:06Tornerevisino number should be posted on FS #9708
18:21:19Torner24440
18:21:47TheSevenTorne: I think i've seen something similar in the usb charging spec, but the usb 2.0 spec clearly says that you may not draw more than a few µA if there is no bus activity
18:22:04TheSeven(which will obviously be the case if you are connected to a dumb charger)
18:22:11TorneAh, yes
18:22:13Tornethat is new
18:22:20Horschtok..., then DMA doesn't help. I am using r24442 and I still get my buffering pause :/
18:22:32Tornehrm, actually it only applies to dead batteries i think :(
18:22:51Torneanyway, i am not that bothered about exactly following the letter of the law
18:23:07 Part wojtek111
18:23:15TheSevenso you'd go for always 100mA, and 500mA if enumerated properly?
18:24:23Torneyes
18:24:28Torneor if D+/D- are detected as shorted
18:24:34Torneor if the magical apple ADC values appear on D+/D_
18:24:45Tornewhich is not really part of the USB spec but is very unlikely to happen by accident
18:25:03TheSevenTorne: and it's also followed by some other vendors, like for example creative
18:25:10Tornethen the "force" mode would, in addition to that, also switch to 500mA if there was no bus activity within some timeout
18:25:29TorneNot all targets can actually implement that charger detection, though
18:25:40TheSevenand "brute force" would be always 500mA, even if enumerated at 100mA? ;-)
18:25:43TorneNo
18:25:48TorneWe're not doing that :)
18:26:20TheSevenwhen designing that, you should also consider devices that can draw 1A, like the iPod Nano 4G
18:26:39TheSeven(even though I doubt it will ever draw more than 500mA, even if allowed to)
18:26:41TorneYour point about 0mA needs considering but even if you rule that out (most hardware can't do 0mA anyway), then "no" still has a bonus feature: you can make it not request bus power at enumeration time
18:26:59Torneif usb charging is disabled when plugged in you can only ask for 100mA
18:27:08Tornewhich makes the player work when connected to a bus powered hub (currently impossible)
18:27:27TorneSo yah, i think this plan delivers quite a few potential features for targets which are adapted to support it
18:27:42Torneand just changing the bool to a tristate doesn't make it any more difficult for the user to understand what the hell is going on, i don't think ;)
18:27:56Tornedoes the 4g actually draw more than 500mA?
18:28:04TheSeveni never measured it
18:28:05Tornethe iphone/touch do
18:28:14Tornethey charge at 1A
18:28:21TheSeveni guess it's actually a relic from the itouch...
18:28:33Torneafaik *all* apple chargers are rated at 1A
18:28:38Torneeven ones made long before
18:28:46Torneand afaik all the PP based iPods *can't* do more than 500
18:28:52Torneexcept via firewire.
18:29:09TheSevento my knowledge even most of the non-apple chargers are rated 1A
18:29:13Torneyah
18:29:18Tornethe USB charging spec allows 1.5A
18:29:25Tornewhich is a weird number but what the hell
18:29:31Torneand the chinese almost-the-same charging spec is 1.2A
18:29:33Torne:)
18:29:37TorneHooray for standards.
18:29:41Tornethere are so many to choose from.
18:30:06Tornebut anyway. if we had suitable detection then yes, i'd let it draw 1A if possible
18:30:10Tornebut *only* if it was detected
18:30:15Torne"force" would still only do 500mA
18:30:36Tornei'm going for minimal probability of hardware damage even if the user *does* pick "force"

21:36:55waran[21:35] waran: I don't know if this is an appropriate question but... how "stable" is the iPod nano 2G port?
21:36:55waran[21:35] waran: Usable (on the edge) or certainly "not recommended"?
21:37:02AlexPIt is not bad - your FTL might get corrupted from time to time
21:37:13AlexPWhich means keep a back up of your music
21:38:21waranI just wonder which MP3-Player to buy (since my last one, iPod nano 1G, went missing (and stolen, I suppose))
21:38:33AlexPDepends what you want
21:38:38waranActually I thought 1G would be nice... but those are very hard to find nowadays.
21:38:45AlexPI wouldn't get an ipod personally, but that is just me
21:39:13waranApple isn't "my company" as well, but I like the comfortable control via the touch wheel :)
21:39:23AlexPNothing to do with it being Apple
21:39:30waranThe firmware/player is pretty much unusable, thats why I use rockbox after all ;)
21:39:32AlexPIt just isn't very good hardware IMO
21:39:41AlexPAnd touch wheels are awful
21:39:45AlexPagain IMO
21:39:54*evilnick_B seconds AlexP's O
21:40:04waranSo which player would you recommend?
21:40:19AlexPDepends what you want - capacity, recording, radio, ....
21:40:41evilnick_BIt depends what you want to use it for, but if you're after a flash player then probably the Sansa E2x0 series
21:40:53waranjust decent playback quality, moderatly high uptime (5-7h) and around 4GB, preferrably flash, storage.
21:41:24AlexPa sansa then
21:41:25*evilnick_B thinks that the v2 versions are probably better than the v1 nowadays (in terms of RB usage)
21:41:37AlexP(one of the supported ones obviously)
21:41:54AlexPThe ipods are fine, just not my choice
21:42:18waranWell, I'll just check the sansas... thanks :)

21:42:35AlexPthere is a bit of an issue with the e200 (v1 only?)

21:44:14AlexPI dislike them
21:44:35evilnick_BThe v1s have the electrical... oh
21:45:25waranIndeed, personal preference. Hower from what I heard the iPods audio hardware isn't actually high quality (at least thats for the 1G nano).
21:45:30waran*However
21:45:39evilnick_BBut that noise is only noticable (in my experience) with decent IEM earphones
21:45:58AlexPwaran: There is nothing inherently wrong with the ipods, I'm just stating my preference :)
21:46:16waranAlexP, they get stolen easily ;)
21:46:23AlexPHowever, it is certain the the nano 2nd gen is less stable with Rockbox currently than some other targets
21:47:17waranI'll bet thats something you (the dev team?) will manage some day using one dirty hack after another :>
21:48:33waranWhat apple could do is to release documentation on "their" hardware, IF they choose to make their default firmware THAT awful.
21:48:44AlexPyeah, good luck

21:48:52waranBut thats as likely as Microsoft releasing their next windows open source :)

22:19:10namnufI'll try to look if I can find what powers the LCD on, I'm not sure of the SSP setup
22:19:36Assemblerhiya if the fuze has 25 MHz Proc. speed and ~1 Mb of RAM, How about sansa e200?
22:19:46Assembler250 MHz*
22:19:49namnufOnly the lcd_write_register function is correct, I didn't find the clock setup and data write (I supposed 16 bits transfer was ok)
22:20:47FlynDicenamnuf: This is you version of dark sunglasses I suppose..;-)
22:21:40krazykitAssembler, which one? the v1 is a portalplayer device and the v2 is AMS like the fuze
22:21:52Assembleryaaaaaaay! ROCKBOX IS STABLE ON FUZE V1!!!!!!!!!
22:22:01*krazykit bets it's documented on the wiki
22:22:01FlynDiceStill no luck with USB but I've had a bunch of interruptions
22:22:09 Quit killan (Ping timeout: 248 seconds)
22:23:06domonokyAssembler: v2 is like the fuze but has 8mb ram. v1 is pp (dual core 60mhz?) with 32mb ram.
22:23:13namnufYou mean you didn't try all the pins ?
22:23:34namnufbertrik: I could extract the Clip+ firmware with utils/AMS/hacking/amsinfo.c
22:23:46domonokyÄh, fuze also has 8mb ram. only clip and m200 have 2mb.
22:23:59namnufHowever some code was not extracted (the string "Batt." contained in the test code was not dumped to a file)
22:24:40namnufthe 'library' detection code looked like hazardous, perhaps it can be improved
22:24:46Assemblerwait wait im confuzed.
22:24:50FlynDiceNo I tried all the pins but some were steady high, I'm trying to see if USB will pull one of them low. After that I move on to your GPIOB write
22:25:03Assemblerwhat is the processor speed and RAM o fuze v1?
22:25:40namnufAssembler: you said the processor speed yourself, domonoky just told you the RAM amount

22:36:17AlexPe200v1 is dual 80 MHz, no?
22:37:21Assemblerim using the fuze
22:37:37AlexPYou also asked about the e200

22:40:02AssemblerTMI one said he lemited the RAM to 0.5 MB rockbox says 1 MB im really confused
22:40:21AlexPI am confused by that sentence
22:41:08AssemblerToo Much Infornation. Someone posted in a forum he limited the RAM to 0.5 MB
22:41:33Assemblerrockbot says Skin RAM usage 28\93 MB
22:41:43AlexPI'm sure it doesn't
22:41:49AlexPThat doesn't make any sense
22:41:59TheSevenwish me luck, guys...
22:42:03Assembleri have just checked it on my fuze
22:42:10*TheSeven is about to try flashing the NOR flash on his ipod
22:42:11Assemblergood luck?
22:42:18pixelmaalso, Skin RAM usage doesn't mean much
22:42:19AlexPTheSeven: Good luck :)
22:42:26Assemblerwhat? whats NOR?
22:42:57TheSevenlet's first sign some recovery images, in case i need them...
22:45:04Assemblerhere System>Rockbox Info>Skin RAM usage 28.0/93.0KB

22:45:57Assemblerwait so it means the e200 has more RAM?
22:46:52AlexPAssembler: Please read the responses you had a few minutes ago last time you asked that
22:47:46Assemblerok
22:48:41Assemblerhay i just got a crazy idea
22:48:46AlexPoh good
22:49:16Assemblerhow about taking a 2GB fuze and adding it a 16 GB microSD and using the 2GB as RAM?
22:49:28AlexPdon't be silly
22:50:31rasherAssembler: flash memory is not fast enough to be used in that way.
22:50:59Assemblerrasher: and a microSD?
22:51:07rasherSame thing
22:51:41Assembleroh brother....
22:51:47Assemblerthe RAM is bothering me
22:51:56Assemblercan i add it RAM is some way?
22:51:59AlexPno
22:52:19Assemblermaybe deassemble it and reaplace its chip?
22:52:39Assemblerlet it be the intire "system on a chip" how they call it
22:52:46AlexPno
22:53:38Assemblerk
22:53:47Assemblerjust a random question
22:53:59Assemblerdo you guys ave windows 3.1 source code?
22:54:13AlexPNo, and stay on topic
22:54:23Assemblerok
22:54:41TheSevendamn...
22:55:08AlexPnot successful?
22:55:20TheSevennot at all
22:56:18AlexPnot dead I hope?
22:56:52TheSeventhe flasher failed - it didn't write anything
22:57:11bertrikFlynDice, there seems to be something on gpio A2
22:58:06FlynDicebertrik: as far as USB?
22:58:08bertrikon other sansas that's the micro sd detect
22:58:33waranthis fuze v1 vs. v2 is mean
22:58:34FlynDiceA2 is one of the pins that was high on reset
22:58:49waranthey look identical O_o
22:58:52bertrikFlynDice, I don't know yet, but it's checked during startup, there even seems to be an interrupt on that pin
22:59:04AlexPwaran: OF version
22:59:15waranOF?
22:59:25TheSevenoriginal firmware
22:59:43FlynDiceUSB did not pull it to low for me
23:00
23:00:33namnufbertrik: you summoned me ? :)
23:03:57bertrikfunman, yes I wanted to know how to adapt clipsplit, but I worked around that
23:03:58FlynDiceThe pins I found high on reset were: A2 B6 B7 C0 C6 D0 D1 D2 D3 D4 D7

23:15:15FlynDiceWell USB does not pull any of those pins low, time for a break and then I'll try the write to gpiob
23:15:51TheSevenany obvious errors in there?
23:16:12 Quit shaggy-h (Ping timeout: 240 seconds)
23:19:09TheSevenok, it seems to have something to do with the delay loops
23:19:34bertrikFlynDice, in the button read routine I'm seeing a read of GPIO D6, but before that one is read, GPIO B0 is made high, then a little delay, then the GPIO D6 read, then GPIO B0 is made low
23:20:05namnufTheSeven: looks ok
23:20:30TheSevenif i just wait some thousand iterations, it'll work
23:20:55TheSevenso i probably missed something regarding the protocol (status detection during a write operation)
