00:06:53	bluebrother	what do people thing about dropping support for OS X 10.4 for Rockbox Utility?
00:09:42	JdGordon	not untill we can drop charcell and hwcodec support!
00:11:17	*	bluebrother sees too many functions with "Available in Mac OS X v10.5 and later" :/

00:24:52	piotrekm	hi, i'd only like to mention that on nano2g rockbox svn sometimes swaps channels in mp3 files (flacs played ok), especially when skipping a track and coming back to it.
00:26:06	piotrekm	oh, it is already a bug FS #10812, sorry
00:26:26	TheSeven	oh no, not again...
00:26:48	TheSeven	piotrekm: can you try verifying that it's really only mp3? i can't imagine that
00:27:07	TheSeven	if it would be related to mp3, it would be very unlikely that only nano2g is affected
00:27:34	piotrekm	TheSeven: sorry, i wasn't specific, in flacs i had not problem, but in ogg and mp3 i did
00:27:41	piotrekm	or maybe it was an accident flacs played ok
00:28:43	TheSeven	piotrekm: please double-check that
00:28:51	piotrekm	ok, doing that
00:28:51	TheSeven	i would expect flacs to be affected, too
00:29:13	TheSeven	but honestly I don't have any idea what could still be causing that
00:29:15	bluebrother	~?
00:29:15	bluebrother	~? ~ ?
00:29:49	TheSeven	We once had an issue where the channels swapped on play/pause, which was fixed...
00:29:59	*	bluebrother curses the network connection
00:30:22	TheSeven	are the channels always reversed at the beginning of a track? or on play/pause? or do they just swap all of a sudden in the middle of a track?

00:34:33	piotrekm	TheSeven: ok, flacs are wrong too. It happens durig playing next/new file, i haven't experienced this during pausing/unpausing or while listening - and i listened quite a lot recently.

00:35:16	TheSeven	ok, so a sample seems to sometimes get lost on the i2s bus when starting playback
00:36:14		Quit mt (Ping timeout: 252 seconds)
00:36:18	piotrekm	TheSeven: what's more curious, when playing a series of short tracks in different formats ("Left Right" from http://binkster.net/extras.shtml), the channels happen to swap quickly for the first second of the file, and then settle down
00:36:21	JdGordon	AlexP: can you file a bug for the wps problems? I dont know when I'm going to get a chance to look at it properly... sunday maybe, but dunno

00:37:24	TheSeven	hm, dma latencies during buffering?
00:37:39	piotrekm	i can record that for you
00:39:58	AlexP	JdGordon: Sure
00:40:41	*	TheSeven will try to reproduce that on his nano later
00:41:52	AlexP	JdGordon: Do you want me to assign it to you?
00:42:10	JdGordon	na
00:42:24	flyback	woot
00:42:29	JdGordon	no need. I'm happy to let someone else fix it if they want :)
00:42:30	flyback	the broken iriver I bought works with the new hd
00:42:34	flyback	next step rockbox :)
00:42:49	flyback	espically since their firmware tools are CANUCKED or their web links are broken
00:42:54	flyback	so I only have a older firmware on it anyways
00:43:02	piotrekm	TheSeven: and about that initial channel swapping, it happens only with the wav file.
00:43:04	JdGordon	just make sure you set the category to WPS and nag me every few days
00:43:06	piotrekm	goodnight
00:43:07	*	flyback ponders purging all traces of iriver firmware from unit
00:43:24	AlexP	JdGordon: Righto
00:43:27	JdGordon	amiconn: you didnt do the boot benchmarking yet I assume?
00:43:31	*	TheSeven would like to do that on his ipod but failed badly
00:45:51	flyback	TheSeven, did you brick it?
00:46:05	TheSeven	no, i didn't even come that far :-/
00:46:16	TheSeven	i failed to flash it at all
00:46:20	flyback	oh ok cause ebay sells a cheap parallel port jtag for $5 and $5 ship
00:46:31	flyback	I have one, I build a led test rig and it passed
00:46:35	TheSeven	flyback: jtag won't help on that device...
00:46:40	flyback	going to try to jtag something this weekend
00:46:43		Part WalkGood
00:46:44	flyback	been wanting a jtag for yrs
00:47:32	TheSeven	apple/samsung used some kind of voodoo to prevent us from using their jtag port properly

05:35:31	Unhelpful	also dual-boot is supported... generally the rockbox bootloader is inserted into the device firmware such that it can load and run the rockbox firmware if not told to boot the OF. details vary from device to device. :)

10:24:13	Unhelpful	amiconn: so "a slow enough codec can cause shutdown" is a semi-known issue on pp? also how hard would it be to make sure udiv32 ends up being the last thing in iram? i was actually thinking that it's almost entirely position-independent, so we could just have the code for it in dram with the table offset set up to put the table immediately after the function, and then copy the function and table to iram before stealing part of the
10:24:13	Unhelpful	table space for buffers. i think it could be set up so that none of the stuff that's larger to allow for this takes up any iram, so that nothing would get any slower than it is now.
10:25:57	amiconn	It's not pp in general, just pp5022
10:26:44	amiconn	And it might be due to target properties not related to code
10:26:45	Unhelpful	hrm, but isn't e200 pp5024?
10:27:01	amiconn	The 5024 is a 5022 with tacked-on AS3514
10:27:11	amiconn	It even reports as 5022 - see debug menu
10:28:31	amiconn	The PP5022 I'm testing on (Mini G2 and c240v1) have significantly smaller batteries than the PP5020 targets, and the SoC does draw significantly more power when running at 80MHz for exctended times
10:28:54	amiconn	So it might indeed cause the voltage to go too low.
10:29:28		Join ender` [0] (krneki@foo.eternallybored.org)
10:29:36	amiconn	Another possibility would be that the low yield rate confuses the powermgmt thread so that it reports low voltage when voltage isn't actually low
10:31:32	amiconn	What speaks somewhat against it is that the two targets I'm observing this on (Mini G2 and c240v1) have different battery ADCs (Mini has PCF50605, c200 has AS3514), while a PP5020 target with the same ADC as the Mini (iPod Color) doesn't show this behaviour
10:31:54	amiconn	(H10 uses a different ADC - the PP built-in one)
10:35:20	*	amiconn isn't actually sure about the iPod Color behaviour, but testing just now

10:52:29	amiconn	Unhelpful: Actually I was wrong. The Color behaves the same, i.e. it shuts down
10:53:38	amiconn	The behaviour is indeed very weird. I started the -c5000 test on Mini G2 and Color almost at the same time. On both ipods, the backlight came on by itself after ~6 minutes and stayed on (!)
10:53:59	amiconn	After another ~6 minutes, the shutdown happened, also on both ipods
10:54:19	amiconn	So it's not just PP5022
10:54:46	amiconn	And since I doubt the batteries behave exactly the same, it must be something in the code

11:56:40	stripwax	mdctexp for vorbis now faster than trunk was mid-april last year. I'll compare vs trunk today :)
11:58:15	Unhelpful	wouldn't that be twiddle^2? or is this another "transforms are funny" thing?
11:58:20		Quit Tuplis (Ping timeout: 260 seconds)
11:58:50	stripwax	they're different twiddles. sorry, I wasn't clear!
11:59:01	n1s	stripwax: on cf too or just arm? also how much benefit does the early termination give?
11:59:24	stripwax	n1s - just arm, cos I've been using my ipod as my test target.
11:59:33	n1s	Unhelpful: have you concidered trying to get your optimized clz and division functions into libgcc?
11:59:37	stripwax	and I haven't written any coldfire asm in .. well... quite some time.
11:59:53	n1s	stripwax: ok, just curious

12:00:08		Join Tuplis [0] (~jani@adsl-77-109-221-158.kymp.net)
12:00:33	stripwax	not sure how much benefit early termination gives, to be honest. Seems like perhaps about 0.5MHz benefit at low bitrates but about -0.5MHz at high bitrates.
12:00:47	stripwax	i.e. slightly worse. but i've not measured that rigorously
12:01:08	stripwax	n1s - you're welcome to take a look / try it out
12:01:14	stripwax	for coldfire, that is
12:01:30	AlexP	So he can't for arm? :)
12:01:39	stripwax	yeah or that too :)P
12:02:07	n1s	stripwax: i would like to but haven't brought any targets with me so i can't for a few months still
12:02:21	Unhelpful	n1s: i'm pretty sure cf has a fixed delay on multiply. armv4+tdmi can take 2-5 cycles depending on how many significant bytes the second input operand has
12:02:31	stripwax	yep
12:03:36	n1s	right, i was more thinking of how much spedup it gave, which stripwax answered :)
12:03:50	Unhelpful	the benefit can be nice if you're multiplying 32-bit values by 8- or 16-bit constants
12:04:27	n1s	yeah, i suppose gcc doesn't know or care about that?
12:05:02	Unhelpful	erm, by 8- or 16-bit values that are non-constant, really, on arm7tdmi. loads cost rather a lot there, so mul-by
12:05:25	Unhelpful	grr. mul-by-constant if the constant exceeds 8 bits is often easier to do with shift/add sequences
12:08:55	stripwax	if it's quite a simple constant .. wouldn't work for cPI2_8
12:12:40	stripwax	the number of mult cyclces actually depends on how many leading 1s' (or 0s') the second input operand has - rather than just how many significant bytes
12:18:02	stripwax	Ok mdctexp is about 0.5MHz slower (at low bitrates) than trunk. still need to squeeze more out

12:22:14		Join domonoky [0] (~Domonoky@rockbox/developer/domonoky)
12:32:49	stripwax	mdctexp quite a lot faster for WMA! gosh.
12:32:55	Unhelpful	stripwax: i was treating all bits after the first one not matching the sign bit as significant... but yes, that's another way of putting it that might be clearer.
12:33:14	stripwax	ah yeah in that case we're talking about the same thing :)
12:33:38	*	Unhelpful supposes differences in speed change by codec mostly have to do with how much of their time is inside mdct
12:34:30	stripwax	and also how large the mdct is. it's likely that mdctexp scales differently for large/smaller block sizes than trunk. not yet sure if that means trunk is better for large or small block sizes though. but vorbis and wma use different block sizes
12:36:35	linuxstb	TheSeven: What's your plan with the NOR on the Nano2G? Are you intending to flash your own bootloader at some point?
12:37:36	linuxstb	And do I understand correctly that you have worked out how to recover from a bad NOR using the DFU recovery mode (built into the boot ROM?) ?
12:42:10	TheSeven	linuxstb: yes, a long-term goal could be replacing norboot. and yes, I can use the bootrom DFU mode for recovery. but only if i can enter it. and it is only entered if image validation for norboot fails, not if there is a valid, but non-working image
12:42:56	TheSeven	in that case, you would need to open up the ipod to unbrick it, by pulling a testpad high (which will force it to enter dfu mode)

17:57:41	bluebroth3r	btw, how do you feel about dropping support for OS X 10.4? Qt 4.7 is likely to drop it, and some of the audio functionality that might be nice is only available starting with 10.5
17:57:55	FlynDice	bertrik: The clip+ pwr button appears to be on D6 as you found yesterday and you mentioned another here−−>[14:41] <bertrik> yes maybe, there's also another pin being made temporarily high while reading D6 Do you recall which one that was?
17:58:23	bluebroth3r	one problem is that the TTS system of OS X creates aiff files, while we need wav. I'm currently using libsndfile for conversion, but it's yet another dependency on a library
17:58:44	*	kugel found his fuzev2 disassembly
17:59:24	domonoky	i am not sure about the 10.4 issue. dont know how many macs with 10.4 are out there.
17:59:59	domonoky	bluebroth3r: or make rbspeexenc accept aiff :-)
18:00
18:00:49	bluebroth3r	domonoky: what about wavtrim? That would need adjustment too
18:01:13	domonoky	true,
18:01:15	bluebroth3r	the thing is that there's a way to convert this with OS X itself, but the API I looked at requires at least 10.5
18:01:23	pixelma	in the office I currently work in, there are a few running 10.4
18:01:50	pixelma	not sure how represantative is

18:02:58	bluebroth3r	well, if I manage to get it working nicely with libsndfile that isn't a reason anymore
18:03:17	kugel	pixelma: isn't the source in all languages wrong now? (re your commit)?
18:03:47	pixelma	yes, and it should be so that translators will have a look at it
18:04:17	pixelma	I don't know if other languages contain the "mp3" part and how they would have to be changed if they do
18:04:17	bluebroth3r	domonoky: would it be hard to make voice generation multithreaded? It's a bit annoying to see it taking quite a while but only using one of the two cores on my mac
18:04:47	domonoky	bluebroth3r: at least for parts of it should be easy.
18:05:27	domonoky	for example the encoding could be easily done paralell with the QConcurrent api.
18:07:15	pixelma	there were no complaints (I saw) about Rockbox USB support being broken during the time it was on MacOS 10.4 (from introducing HID until it was possible to disable it) so maybe not that many Macs with 10.4 and Rockbox USB target users)
18:07:18	bluebroth3r	I'm not really familiar with that API. Did a bit of looking into QThread but that's it. Might be worth a try.
18:08:14	domonoky	creating voice files is similarly easy todo in paralell, but i am not sure if all tts engines we use are multthread safe.

19:29:10	linuxstb	TheSeven: Yes, I meant to say NOR ;)
19:29:29	linuxstb	TheSeven: Does the DFU payload need encrypting?
19:29:30	bertrik	the meizus and the samsung yp-s3 (s5l8700 targets) all connect the go-to-DFU mode to a physical button
19:29:37	TheSeven	linuxstb: yes
19:29:55	linuxstb	TheSeven: With which key?
19:30:01	TheSeven	GID
19:30:11	TheSeven	but there is a buffer overflow in the dfu code itself that could potentially be used, even though I didn't manage to exploit it yet
19:30:15	linuxstb	That's the same as the firmware images on the NAND ?
19:30:37	TheSeven	bertrik: didn't they do it through the BOOT_MODE pin?
19:30:54	TheSeven	linuxstb: the key, yes. the container format is a little different
19:31:07	TheSeven	they're using a total of 3 crypto container formats!
19:31:34	linuxstb	TheSeven: OK. But the important thing is that it can be generated once, and then used on any ipod?
19:31:41	TheSeven	yep
19:32:14	TheSeven	so you can use a different ipod to recover you own one ;-)
19:32:31	linuxstb	Yes, the alternative would be a bit tricky ;)
19:33:50	TheSeven	i already made a DFU image that contains the most recent ibugger loader
19:34:04	TheSeven	so we can basically use that to run whatever we want on it

23:04:26	TheSeven	linuxstb: basically yes
23:04:43	pixelma	domonoky: need to google for that

23:11:08	domonoky	pixelma: ideally you should run lupdate rbutilqt.pro before translating to make sure you got the newest string. but then you need the full qt enviroment.

23:12:06		Quit Adub- (Read error: Connection reset by peer)
23:12:31	domonoky	pixelma: or just use this http://pastebin.com/m1adfe180 rbutil_de.ts file (i just lupdated it) :-)
23:14:15	pixelma	I'd also wish the Utility would stay in the generate talk clips window when ready - or at least keep the setting for installing talk clips for files or not
23:14:31	TheSeven	linuxstb: sounds like my loader works ;-)
23:15:11	amiconn	bluebroth3r: Nope. The encoding used for voice files is either bitswapped mp3 or speex, depending on target ;)
23:15:14	toffe82	I have a funny message with rbutil 1.24 : target mismatch detected : installed target : gigabeatf , selected target : Gigabeat F / X
23:15:32	toffe82	is this due to the change of the target name ?
23:16:06	domonoky	toffe82: yes.
23:16:15	toffe82	ok
23:16:20	domonoky	gigabeatf is now named gigabeatfx

23:17:57	amiconn	domonoky: Does the version of 'lupdate' matter?
23:18:55	domonoky	amiconn: probably not much, i would expect the .ts format to be pretty stable in qt.

23:27:27	pamaury	how does the build script measure binsize increase/decrease ? I would like to test on my computer to know whether some optimizing are worthless or not
23:28:58	linuxstb	See the rockbox-info.txt file created by the build system (as part of make zip I think)
23:29:30	pamaury	thanks !

23:40:22	amiconn	domonoky: Hmm, I just tried to build rbutilqt, and it worked (the only package I had to install was libusb-dev, as I already hat most of the Qt stuff installed for buliding quassel)
23:40:42	amiconn	It seems that the encoding for Turkisch in the language selection dialog is broken
23:40:54		Quit Buschel ()
23:41:00	TheSeven	linuxstb: success!
23:41:11	TheSeven	i just replaced norboot on mine, and it works flawlessly!
23:42:06	amiconn	It reads T<black-square-questionmark>rk<black-square-questionmark>e (tr), whereas the other languages are either displayed properly, or with a few no-such-character rectangles
23:43:00	*	domonoky sees T<rectangle>rk<rectangle> (tr) with svn
23:43:29	*	amiconn slaps forehead
23:43:41	amiconn	That working copy is some 2000 revisions behind...
23:45:27	amiconn	Hmm, more languages but Turkish still broken
23:45:33	*	amiconn tried a full rebuild
23:45:36	amiconn	*tries
23:46:03	amiconn	Didn't help...
23:46:12	domonoky	hm, which os ?

23:46:36	amiconn	Debian-amd64
23:46:39	amiconn	Qt 4.5.3
23:46:54	*	domonoky has Qt 4.5.0 on windows :-)
23:49:51	piotrekm	TheSeven: you mean you booted rockbox without the apple logo being displayed?
23:49:56	amiconn	This looks like Turkish isn't properly utf-8 encoded
23:50:08	TheSeven	piotrekm: not yet
23:50:11	*	amiconn wonders where the language names are coming from
23:50:44	TheSeven	that will be the next step
23:50:56		Quit rhodan_ (Ping timeout: 276 seconds)
23:51:06	TheSeven	but i have a way to do that with a relatively low bricking risk now
23:51:36	TheSeven	(a tiny loader that will go to a recovery mode when you flick the hold switch quick enough after a reset)
23:54:14	bluebroth3r	something with the turkish translation is definitely broken.
23:54:23	*	bluebroth3r wonders if he hit a Qt bug
23:55:03	bluebroth3r	looks like QString::toLocal8Bit() does the same as QString::toUtf8() on Mac. At least when building with gcc-4.2 for OS X 10.5 upwards
23:55:10	*	bluebroth3r goes trying with gcc-4.0
23:56:25	domonoky	amiconn: the language name comes from the .ts file.
23:56:29	piotrekm	But is the norboot part responsible for any tasks that would have to be covered by rockbox after the replacement?
23:57:42	amiconn	domonoky, bluebroth3r: The encoding of that file is wrong then. Check e.g. line 329
