14:19:15pamauryI would like other developpers opinion. I would like to handle the imx233 and the stmp3770 with the same codebase since there are pretty much the same except for a few things here and there. What would be the best option ? use imx233 and #define HAVE_STMP3770 ?
14:22:19pamauryor have a #define IMX233_VARIANT with two possible values: VARIANT_IMX233 and VARIANT_STMP3770 ?

14:52:40gevaertsThat could work. I'm not sure if it's a good idea to do that for one case without at least having plans for doing it elsewhere though. On the other hand, this is a bit of an area where I'm not too involved
14:53:42pamauryyeah, that's true. Then perhaps a HAVE_STMP3700 will do

14:59:13bertrikpamaury, congrats on the sd
15:01:35bertrikthe start of a new port, getting things to work for the first time, is usually the most fun (at least for me)
15:02:31pamaurythe biggest problem to me is that the creative zen style m300 does not seem to have external memory, only 512Kb of internal sram
15:03:20bertrikdo we have PCB scans of it somewhere?
15:04:14pamauryyes, I have photos of it, only of side of the PCB though, the other one is hardly reachable but from what I saw there is not chip. See the wiki: akismet
15:04:32pamauryI made some nice boxes :)
15:05:49 Join maraz [0] (
15:06:07pamauryi might be wrong of course but the OF doesn't initialize the emi from what I saw and it has a very weird architecture. I suspect some parts of the code work like codec, they are loaded on demand
15:07:08***Saving seen data "./dancer.seen"
15:08:05bertrikhm, 512 kB isn't nearly enough to run rockbox on it, I guess. What part do you have working now, lcd and sd?
15:10:11pamauryonly sd yet because I have a generic "recovery util" that I can load and poke at the ssp, I've not yet really started to look at the OF code but I'm really embarassed because the OF file has some "data section" that actually contain code and I'm not sure how it works
15:10:46pamaurythere is still a slight chance that I missed the dram on the board and haven't found the emi init yet
15:11:53bertrikdoesn't the clip v1 have 2 MB of memory inside the SoC package?
15:23:18kugelpamaury: stmp37xx is a soc similar to imx233?
15:23:31pamauryyes, it's an older version, more or less
15:24:28TheLemonManpamaury: i have some bsp code adapted to the stmp37xx register layout, if you're interested in it just whistle :)
15:24:34kugelah so it's comparable to PP indeed
15:24:52pamauryTheLemonMan: I produced a pdf file of the difference between imx233 and stmp37xx
15:25:43TheLemonManyep, i could spare you some time adapting the code
15:26:03TheLemonMandont have enough free time to actively develop the port :( at least till summer
15:26:41gevaertsscorche: if I make more forum changes, do you prefer those as patches on top of the previous one, or on top of pristine akismet/smf?
15:28:46 Join n1s [0] (~n1s@rockbox/developer/n1s)
15:32:12pamaurywhat I'm afraid of is that the OF could use paging and page fault handling to simulate a larger memory using the sd as a backend, that would make the OF analysis pretty hard

15:53:45kugellorenzo92: I noticed something strange. sometimes it has 100% cpu usage, most of it spend in the kernel (sys time also 100%
15:54:17lorenzo92kugel: yep. This is due to bad filesystem... -> do a fsck.vfat and you will see that it is solved!
15:54:25lorenzo92kugel: anyway, great as always :D
15:59:10lorenzo92kugel: I was thinking, as a workaround we could write a script that, let's say after 10 reboots, executes a fsck.vfat directly on device
15:59:37lorenzo92well I should check if that really works and doesn't block the device for too much time :)
16:01:50[Saint]That's a bit of a hack...
16:02:29[Saint]Better to find out why the fs is getting trashed, no?
16:03:53lorenzo92indeed...The thing is that behind there's the RFS (for which I found its sources, tough lol)
16:04:20gevaertshm, interesting bug
16:08:42gevaertsscorche: if I create a new topic, and then a spammer replies to that, and akismet intercepts that, and then a mod clears the akismet queue, that topic is no longer listed
16:09:42gevaertsIt still exists, and it's still listed as the most recently modified topic in the board list (well, if it is the most recently modified topic), but it's not listed in the list of topics...

16:33:13gevaertsscorche: I think is worth applying. It's based on clean smf/akismet, and adds (a) hiding spam from recent posts (same as the previous patch), (b) links to user profiles from the akismet spam list (so we can look at sigs or ban easily), (c) deleting spam from individual users from the akismet spam list (which should make dealing with false positives a lot easier), and (d) it doesn't set the last message information on a
16:33:25gevaertstopic if the last message is spam (which should fix various issues with things looking weird)
16:34:21gevaertsI'd still like to add a way to report spam to akismet if it missed it, but I'm not sure where that should be shown

17:30:20ToxAtechi, I'm wondering if it's possible to disable charging a sansa fuze v1 on USB connections, or if rockbox has no controll over charging the battery. I saw that there was an option like that on other players (some ipod).
17:30:47Torneif the option isn't there then it's not implemented; whether it's actually physically possible, I don't know
17:30:55Tornebut if so, nobody has written the code for it
17:31:28 Quit SynrG (Ping timeout: 252 seconds)
17:32:19bertrikWe can control charging on the PP, AMS, AMSv2 sansas (enable/disable charger, configure charge voltage and current)
17:32:20 Join TheLemonMan [0] (
17:33:06TorneToxAtec: also note that turning usb charging off doesn't reduce the power used to zero
17:33:07bertrikbut I don't see why you would want to disable charging
17:33:39Tornebertrik: generally, to avoid draining the battery of a laptop that's only going to last a few hours in order to recharge an mp3 player that will last all day :)
17:34:38ToxAtecI thought it might be better for the battery health if you don't start charging it everytime you add a new song; also I found out about the USB HID fuction which would be a perfect scroll wheel for my laptop
17:35:09Tornethe effect on the battery will be probbaly unmeasurable no matter what you do with it
17:36:46bertrikcharge current for a sansa is probably only a fraction of what the laptop itself already uses
17:37:38Tornebertrik: the other reason is to work with broken usb hosts/hubs that can't deliver the power in the first place
17:37:53ToxAtectorne, did you mean the effect on the laptop or fuze battery?
17:37:53bertrikand lithium batteries don't mind if you recharge them often while not empty yet
17:37:59TorneToxAtec: on the fuze battery
17:38:23TorneWell, also the laptop :)
17:39:26Tornebut it depends how you are using the laptop; it'll suck up to 2.5W from the host, which is not a lot compared to a laptop's display, but is possibly measurable if the screen's off :)
17:40:48Tornebertrik: anyway, the option is there because it's easy to do if you already hve the underlying system for charging in a USB-spec-compliant way
17:40:54gevaertsWell, it will only do that if it actually needs to charge
17:41:02Torneif we have the required level of control over the hardware on AMS then we should hook it up
17:41:28Tornein theory the code should be target-neutral after i refactored the beast/ipod support for it
17:41:40bertrikI'm still confused about the need for this. Never heard of anyone having a real problem with the current situation.
17:42:03bertrikyes, it could be done in some generic charging state machine I guess
17:42:10Tornewe already have the generic charging state machine
17:42:19gevaertsbertrik: spec compliance and having all targets behave the same way
17:42:33TorneYou just need a #define to enable it, and implement the underlying control functions in target code
17:42:40Tornethe PP ipods and the gigabeat S have this already
17:42:44Torneand the nano2g i think
17:42:54Tornei wrote this at the devcon in 2010 :)
17:43:14Torneand tested on every PP ipod model with a multimeter, whcih was fun :p
17:43:59 Join lazy [0] (
17:44:04 Nick lazy is now known as lazyguy (
17:45:48lazyguyin the targetstatus, clip+'s usb functionality says yes, but under release 3.1 it's says it's still disabled
17:46:17gevaerts3.1? The clip+ didn't even exist back then...
17:46:35gevaertsIf you mean 3.10, USB was enabled after that
17:46:49lazyguyya 3.10
17:47:06lazyguyso do i need the current build
17:47:12lazyguyor 3.10 is fine
17:47:48gevaertsWell, if you really want USB in rockbox, you need a current build, yes. If you're happy with rebooting to the original firmware, 3.10 is fine
17:48:02lazyguyok thanks
17:48:21gevaertsNote that USB in rockbox might still be a bit unstable. It works well for many people, but it's still relatively new code that hasn't seen very wide testing
17:48:29bertrikTorne, gevaerts, there is a simple state machine to control charging for the as3514/AMS sansas, but it looks like it's not hooked into the new USB/charger detection logic yet
17:49:19lazyguyguess i'll wait then
17:49:27lazyguyi;ve been waiting for years now anyways
17:50:02gevaertsWell, there is of course also the fact that if everybody waits, we'll never know if it works well :)
17:50:06Tornebertrik: well, if you have a go i will take a look at your patch :)
17:50:33bertrikTorne, the stuff you wrote does the 100 mA / 500 mA / "unlimited" detection, based on USB attachment status, charger detection, etc, right?
17:51:23Torneit only ever actually selects 100 or 500, currently
17:51:24lazyguyok, updating now
17:51:36Tornebut if possible the underlying code should handle 0 and unlimited as well
17:51:37lazyguyguess i'll just tell you if it works or not
17:51:39Tornefor future use
17:51:59TorneWe don't currently have any charger detection code
17:52:13Tornei've not gotten around to doing it for ipodvideo yet, and i don't know how to do it on any other devices :/
17:52:21lazyguyalso, i have some superold bootloader, that didnt change or anything right?
17:52:29kugelrockbox on webos seems like a no-go
17:52:48kugelsdl on it only supports sw surface and that's way to slow
17:53:44bertrikI could possibly help with a nano 1g, but IIRC last time I trie I came to the conclusion we can't measure the special resistor networks in the nano 1g
17:54:09kugelCaptainKewl: ping
17:54:11amiconnDetecting classic charger on ipods is simple is?
17:54:31amiconnThe 12V chargers are essentially firewire power
17:54:46TorneOh. That's irrelevant
17:54:50Tornethis is for USB charging only
17:54:53amiconn..which is supported by all PP ipods, even those which don't support firewire data
17:54:56Torneby "classic" there you mean "ancient"
17:54:59Tornei think :)
17:55:05Torneall ipod chargers i have or have seen are 5V
17:55:29CaptainKewlkugel hi
17:55:52kugelCaptainKewl: sdl on webos is too slow to be useful at all
17:58:07gevaertskugel: is sdl the only option?
17:58:51CaptainKewlsoftware, yeah. I got it to run faster by using opengles and rendering the surface to a texture and displaying that instead
17:59:31kugelshow me!
17:59:48kugelI was always interested in us doing opengles :)
17:59:58CaptainKewlhaven't checked the fps but it runs in hybrid without taking 2 seconds to render each frame
18:00:15kugelI can check the fps if you give me the code ;)
18:00:30CaptainKewlI'll see if I can post it up in a bit, will need to reboot
18:00:54 Quit CaptainKewl (Quit: ( :: NoNameScript 4.22 :: ))
18:02:18kugelgevaerts: sdl and opengles, I think. Perhaps fbdev but haven't tried
18:02:37kugelopengles would be interesting for android too methinks
18:03:02gevaertsWorth looking at, anyway
18:03:12gevaertsI suspect fbdev won't be an option on webos
18:03:15kugelthe docs say with opengles you're limited to landscape, though, unless you roate in-app which we can't
18:04:13kugelwell, we actually can as mpegplayer shows
18:04:23amiconnTorne: I thought the charging state machine would handle all potential power sources
18:04:45gevaertskugel: you can rotate within opengl
18:04:52Torneamiconn: no; i'm not aware of a need for it to do so
18:05:02lazyguyare there special drivers for clip+
18:05:05Torneit's specifically about telling the usb interface what to do
18:05:18lazyguyif you load from rockbox
18:05:25kugelgevaerts: the opengles implementation on the touchpad can'T :)
18:05:30Tornecharging direct from a DC port, or from firewire, doesn't come with any special behaviour or rules that i know of :)
18:05:31kugelaccording to anyway
18:06:50funmankugel: not yet
18:07:38gevaertskugel: that sounds like something different. The main viewport will probably always be 1024x768, but what you draw in there is up to you. You can render to a 768x1024 texture, and then rotate that texture before putting it on a surface
18:07:47Torneamiconn: this is not about the actual charging thread/etc, the state machien that runs software controlled charging. this is specifically inside the USB stack, to handle the power requirements in the USB spec
18:07:51kugeli will just commit then. it's mostly an infrastructure change
18:08:03Tornedevices that have software-driven charging still have an independant system to actually run that
18:08:26kugelgevaerts: well sure, that's what I meant with "rotate in-app"
18:08:59gevaertskugel: well, it's two lines of code :)
18:09:10lazyguyokay, i unplugged usb and now rockbox is stuck on the usb screen
18:09:22gevaertsWhich are in the opengl/es specific bit
18:10:02kugelwell yes, but you need to translate touch events also
18:10:07Torneamiconn: the bit that's interesting is the USB stack telling the power managemen system whether it's okay to draw power from the USB +5V pin. if you have some other source of power then that's not the USB stack's problem ;p
18:10:42 Join factor [0] (~factor@
18:11:22gevaertsright. That shouldn't be too hard though

18:15:18gevaertsyes, hold a button while plugging in.
18:15:51gevaertsSelect is probably a good choice. That will bring up the context menu, but that's easy to get back out of, and doesn't do anyhing
18:17:24dfkthow do i update my local patched tree with git? git pull −−rebase refuses to update, it says "refusing to pull with rebase: your working tree is not up-to-date"
18:17:41bertrikwhere (in the source) is the code for determining if it's okay to draw power from USB?
18:18:28bertrikand is it a poll mechanism (asking USB), or does USB just tell someone else what is allowed?
18:18:54Torneusb_charging_maxcurrent tells you how much you can have right now
18:19:05Torneusb_charging_maxcurrent_change gets called when it changes
18:19:16Torneit's in usb_core.c, under HAVE_USB_CHARGING_ENABLE
18:20:32lazyguycool thanks it worked
18:20:46scorchegevaerts: email me if you could and i can get to it when i get back
18:20:57gevaertsscorche: ok
18:21:27lazyguyi got a touchpad you guys need help testing
18:21:33lazyguyif you're still talking about that
18:21:36scorchegevaerts: please roll all the changes into one - i am going to try to make a SMF package from it - which i think means i need the entire file of anything you have modified
18:21:38Tornebertrik: calling the usb stack to ask is cheap, so if the target already has a software charging thread polling for stuff to prod the charge controller, you can just add the call in the polling loop.
18:21:59Tornebertrik: if it's like the ipod where you just poke a hardware register to tell it what the limit is, you can just implement the on-change function
18:22:10Tornedid it this way to accomodate both

18:29:13bertrikTorne, and what if the sansa is connected to a charger, should I detect that myself, and ignore the max current advice from the USB stack?
18:29:38Tornehandle it however you handle it now
18:29:45Torneexcept presumably now you assume USB means 500mA
18:30:04*bertrik isn't actually sure we can distinguish between USB power and charger power
18:30:16Torneif you can't, then assume it's USB
18:30:21bertrikwe're charging with only 300 mA max anyway
18:30:29Torneyes, but 300 is more than 100
18:30:35Tornewhich is all you are allowed to draw without negotiation
18:30:42 Quit lazyguy (Quit: ChatZilla 0.9.88 [Firefox 9.0.1/20111220165912])
18:31:35Torneif the charger provides power on +5VUSB, like most do, and you have no known way of telling the difference, then you are in the same position as the ipods are. if the user picks "force" it will ignore the lack of positive charger detection and allow high current charging after a host doesn't show up within a reasonable time (the code does this for you)
18:31:39bertrikand USB draw = player consumption + charger current, so we better turn the charger off completely when in 100 mA mode
18:32:02Torneif you can power the device without charging it, then sure.
18:32:20Torneon the ipods, the regulation is global, so if you limit the usb power to 0mA and the ipod's battery is dead, it will just die :)
18:32:40Tornewhich is.. not ideal. which is why the logic doesn't do that yet

19:01:43ToxAtecthis USB charging discussion is interesting, although I guess I would not be able to implement anything or so :P but what I think I understood is that controlling USB loading on a sansa AMS is possible but "it's not hooked into the new USB/charger detection logic yet"? So you need some function to tell the.. state machine (?) what has been detected on USB, like 100mA or 500mA?

20:31:04funmanwhen rebasing you must remove your lcoal diffs
20:31:10jhMikeSfunman : I've got that same thing set up automated if the basic pull fails :)
20:31:25jhMikeSor commit the changes first
20:31:36gevaertsdfkt: git basically refuses to do anything if you have untracked changes. You need either git stash to put modifications away for a while, or make a local commit
20:31:50n1spamaury: i think it's juat to be safe, it *should* probably never be called with such rectangles
20:31:53Tornecommit early and often :)
20:31:54funmanyou can pull (without rebase)
20:32:06gevaertsIt *is* intuitive if you've studied it for long enough :)
20:32:14dfkti sure wish git was a bit easier to comprehend, like svn...
20:32:17Tornefunman: well, sort of. If you get into the habit of doing that once you actually have local commits you'll be creating merges, though
20:32:27kugeldfkt: most people do :)
20:32:34Torneand even with a merge it won't let you pull changes that touch the same files, even if they don't conflict
20:32:45dfktso i should use funman's line as an equivalent to a good old "svn up"? ;)
20:32:53Torneyes, more or less
20:33:12Torneit basically commits your changes for you, but puts them aside, then pulls from upstream and applies the temporary commit on top again
20:33:19*jhMikeS has under [alias]: up = !git pull −−rebase origin master || (git stash -q && git pull −−rebase origin master && git stash pop -q)
20:33:27Tornewhich will introduce coflict markers if things conflict, which is what svn up does :)
20:33:52Torneyou might want to consider just.. making actual commits more often, thoguh :)
20:34:21*pamaury hopes kugel will soon correct all errors and warnings :)
20:34:22gevaertsAs soon as we have gerrit up and running this particular use case will slowly change
20:34:41Torneyeah, sorry about that
20:34:46Tornei need to write the stuff for that real soon :)
20:34:50*jhMikeS never know what a commit message will be until acutally finalizing the whole shebang
20:34:58TornejhMikeS: you can rewrite it as often as you want
20:35:14gevaertsTorne: I'm not complaining, really just pointing out a benefit :)
20:35:34jhMikeSyeah, there's a −−revise (or whatever it was)
20:36:15jhMikeSaha, that's it
20:36:23Torneyou can also use interactive rebase to flatten multiple commits into one commit (and it'll merge their messags, or throw them away, as you choose)
20:36:28CIA-81Commit 74c8746 in rockbox by Thomas Martitz: Don't filter out -O for sims.
20:36:29Torneso yeah. just make commits locally :)
20:36:40Torneonce yo uare done you can squash them together and rewrite the message
20:37:12dfktjhMikeS, where do i find this [alias] section?
20:37:31kugeldfkt: better use jhMikeS' line. if there's nothing to stash than stash pop will harm :)
20:37:43dfktstash pop sounds illegal anyways :D
20:38:15jhMikeSdkft: in .git/config, if not there add it, and define any shortcuts there
20:38:47Torneseriously though, committing is safer
20:39:07Torneonce you have committed the changes you can trivially revert to the earlier state if you make a mistake when resolving conflicts/etc
20:39:19CIA-8174c8746 build result: 0 errors, 43 warnings (Thomas Martitz committed)
20:39:21Torneusing the stash, this is more difficult
20:40:27gevaertskugel: that's why it was filtered :)
20:41:12Tornealso if you stash and pull, this will still not work if you have created a local file that now exists in upstream ;)
20:41:17n1si'd guess it was fro debugability and build speed too
20:41:20Tornesince stash doesn't touch untracked new files
20:41:34Torneso the pull will still fail, because it'll refuse to overwrite the existing file

20:42:57kugeln1s: you can debug code at all levels of -O
20:43:36kugelyou might want to avoid "parameter optmized out" but then you want -O0 instead of nothing

21:19:09gevaertsIt's not

21:19:44jhMikeSsay what?
21:19:46n1sperhaps sizeof is broken for this case
21:19:56kugelgevaerts: what is storage_*_sectors supposed to return?
21:21:20gevaertskugel: IIRC 0 on success, a (negative, I guess) error code otherwise
21:22:24gevaertsn1s: what's "t_datachunk *aiffdc = (t_datachunk *)headerbuf + sizeof(t_aiff);" supposed to do?
21:23:48CIA-81Commit 7dd65f7 in rockbox by Thomas Martitz: Another attempt at fixing storage_*_warnings. Correct return values also.
21:24:01*n1s is no expert on this!
21:24:42gevaertsI'd say it tries to leave toom after headerbuf for one t_aiff object, but I'm not sure it does that. What's the precedence here again?
21:24:51*gevaerts asks Torne to have a look at this
21:24:53n1si'd guess it creates a pointer at offset sizeof(t_aiff)*sizeof(t_datachunk)
21:25:17gevaertsYes, but that sounds weird
21:26:05Tornethe cast binds tighter, so yeah.
21:26:08CIA-817dd65f7 build result: 0 errors, 1 warnings (Thomas Martitz committed)
21:26:38Torneit's equivalent to headerbuf[sizeof(t_aiff)] if headerbuf was a t_datachunk[] :)
21:27:03Tornepretty sure. which as you say, sounds obviously wrong.
21:27:08gevaertsIf that's the case, it might well be overflowing the headerbuf array, which is on the stack and therefore reasonably close to aiffdc, so this could actually be genuinely overlapping data
21:27:39Tornei think they mean it to be sizeof(t_aiff)+sizeof(t_datachunk)
21:27:49Tornebut there's no particularly elegant way to write that using actual pointer arithmetic :)
21:28:01gevaertsNot sure
21:28:18gevaertsI'd say it should be (t_datachunk *)(headerbuf + sizeof(t_aiff))
21:28:23gevaertsheaderbuf is a char *
21:28:37Torneyes, that's plausible also
21:28:42gevaertsWell, a char[] to be precise
21:28:43Torneif t_aiff is the first thing in memory
21:28:54TorneBut in that case, yes, you need the parens
21:29:00Tornebecause the precedence is wrong
21:29:17kugelhow about "t_datachunk data[];" it t_aiff?
21:29:25gevaertsIt's trying to write an AIFF header. We should be able to find out what that's supposed to look like

21:33:04gevaertsThat writes SSND immediately after the equivalent of the aiff_t bit in d_soundfile.c
21:33:34gevaertsSo I'm pretty sure it's supposed to skip sizeof(t_aiff) bytes after headerbuf
21:33:43gevaertswhich means (t_datachunk *)(headerbuf + sizeof(t_aiff))
21:34:06jhMikeSthe recording codec does in as basic a way as it gets
21:34:16jhMikeSprobably the intent, yes
21:34:25*gevaerts fixes it
21:34:30Torneso yeah, that's just someone forgetting that casts are higher precedence than arithmetic
21:34:40gevaertsAnd then not testing :)
21:34:49Tornewell yes ;)
21:35:57kugelthat datachunk should be part of t_aiff, really
21:37:05n1sgevaerts: seems your guess was correct i think, judging from;a=commitdiff;h=c2a3380c00e6aea9c7505651997937e08d922fdc;hp=de1b2d1defa5a1f7cd48b6adb5bcd3083e6b636a
