#rockbox log for 2008-11-30

00:01:22tical2kI got a Belkin car device that connects to the dock plugin and has some basic (pause/play next and previous) functions on it. They currently dont work with rockbox. I noticed a lot of the remote accessories dont work with rockbox. Is there any development in progress on this?
00:02:35tical2kthanks for the info
00:03:34*gevaerts likes this e280. Rockbox usb is extremely unreliable on it

00:21:49tical2klinuxstb, thanks again for the info the patched build works for my device
00:24:39skiyalso folks, just a quick and (probably stupid) question, does rockbox support ogg-vorbis/flac on the "Archos Jukebox Studio 20 20GB"
00:25:10skiyI heard it said somewhere that it didn't support ogg/flac but thought I'd check before buying one off ebay..

00:39:34kugelskiy: they cannot play anything but mp3, because they have a dedicated chip for that, and not a general purpopse cpu like newer daps
00:39:48kugelit's not a rockbox issue, it's a limitation of the hardware
00:40:00 Part beylulbahta
00:42:26scorche|shthen have a "general purpose cpu"...just one that runs at 12MHz...
00:43:07kugeloh, sorry then. But not powerful enough, so basically not usable?
00:43:18scorche|shnot for decoding ausio
00:43:22*scorche|sh cant type
00:43:42scorche|shwhat else would we run all the other non-decoding processes on?
00:44:32kugelyea, sorry. Of course they must have such a thing.
00:44:59kugelI was basically saying, they don't have such a unit like new daps, as in they don't use it for decoding unlike the newer ones

01:08:34amiconnI just get silence....
01:08:59amiconnAlso there are some todo's in decoder.c related to 8 bit streams
01:09:19linuxstbI'm 99% sure I tested mono streams. Have you tried them with demac?

01:11:19amiconnThe comment is suspicious - it says "do nothing unless it's 8-bit audio". I would think that it does at least need to SCALE()
01:11:46 Quit lasser (Read error: 110 (Connection timed out))
01:12:04amiconnAnd guess what - if I do that, it plays...
01:12:23amiconndemac won't have this issue as SCALE() is a no-op for non-rockbox
01:12:56kugellinuxstb: lcd_enable might have been a wrong guess, it does at least something which isn't as optional as lcd_enable should be

01:15:42linuxstbamiconn: Are you talking about 8-bit or mono? Or was your test 8-bit mono?

01:16:49linuxstbAh yes, I see now.
01:17:08 Quit ibseo ("quit")
01:17:50linuxstbI guess that comment is based on what the original source does. You're of course right that we need to scale it for Rockbox.
01:18:18amiconnWhat do you think about this solution: (the #if0 part is svn for comparison)
01:18:59amiconnIt uses the same system as is used in some other places to handle 1 or 2 channels without if/else
01:19:28amiconnWithout making the whole loop conditional, I mean
01:19:39amiconnIt's a little slower though
01:20:06 Quit domonoky1 (Read error: 104 (Connection reset by peer))
01:21:00JdGordoninteresting patch just submitted...
01:21:00amiconnOn a related matter: What would be needed to support 8 bit?
01:21:46kugellinuxstb: was that one directed to me (with the original source)?
01:21:59kugelJdGordon: which?
01:22:12JdGordon"Philips GoGear HDD16x0/HDD63x0 patches for power, sound, buttons, lcd"
01:22:29linuxstbkugel: No, I'm just replying to amiconn at the moment...
01:23:15amiconnAlso, couldn't be 8-bit also be pseudo-stereo, i.e. there's another conditional missing?
01:23:53kugellinuxstb: ok, could've been very well an answer to my lcd_enable "question" too
01:25:00linuxstbamiconn: I would have to look at the original Monkey's source - maybe pseudo-stereo isn't used for 8-bit streams. Your patch looks nice, but as you say, it's a little slower, so I would probably prefer more if/else statements.
01:25:10amiconnThe if(decoded1) *decoded1++ = left costs about 0.2 MHz on PP5022
01:25:53amiconnBut these loops are small, so they can be split
01:27:08amiconnentropy.c has similar loops, but then they use largeish static inline functions, so splitting them would inflate the code quite a bit
01:28:05 Quit domonoky (Read error: 110 (Connection timed out))
01:31:30*amiconn has a hard time reading the original monkey's audio source
01:31:33amiconnIt's C++ :(
01:31:36*linuxstb too
01:33:05linuxstbBut doesn't demac already handle 8-bit pseudo-stereo - along with all other bit-depths in the same part of decoder.c?
01:36:10linuxstbIf you look at lines 259 onwards of Prepare.cpp, it seems that it converts 8-bit streams to an unsigned 8-bit value. So for Rockbox, we wouldn't need that, and can just scale (IIUC).
01:37:04linuxstbkugel: What is "optional" about lcd_enable?
01:41:26amiconnlinuxstb: Prepare.cpp is for encoding?
01:41:41linuxstbThere are two classes in there - Prepare and Unprepare
01:41:59linuxstbUnprepare is the decoding part

01:43:19kugelexcept maybe that it has less battery runtime
01:43:51amiconnlinuxstb: demac.c doesn't seem to handle 8 bit. It checks for 16 bit / 24 bit explicitly.
01:45:02amiconnAfaik 16 bit (and higher) samples are usually signed, while 8 bit samples are usually unsigned. Do you think libdemac should handle that, or demac.c?
01:45:24*amiconn would like to have a 24 bit testfile...
01:46:40 Join toffe82 [0] (
01:49:04linuxstbamiconn: I'm not sure about 8-bit at all... Let me see if I have a 24-bit file somewhere.
01:50:04amiconnMaking an 8 bit testfile from 16 bit should be simple (e.g. using audacity). Making a 24 bit testfile from 16 bit wouldn't make sense (low bits would be all-zero)
01:51:06amiconnSeems like the original code only uses pseudo-stereo for 16 bit.

01:57:07kugellinuxstb: And our Fuze's lcd enable does something that's not optional, but needed, as it's not working without.
01:57:20kugellinuxstb: even though, the bootloader works, which doesn't define that
01:57:41amiconnlinuxstb: Btw, the mono predictor is 3x as fast as the stereo predictor on PP, even though it's C vs. asm.
01:58:10kugellinuxstb: I #if 0'd the else part and it works for now.
01:58:44amiconnThe other parts are almost exactly twice as fast, as one would expect
01:58:50kugelI'll investigate that later. Btw, I think I understood the disassembly pretty good. At some points I still stuck though
02:01:14kugellinuxstb: I've for example noticed noticed the OF does 1 lcd_write_reg more in lcd_window_y that we have in our driver, although it doesn't seem to change much
02:01:41linuxstbkugel: I remember simplifying those window functions - check the svn history.
02:06:08linuxstbJdGordon: IMO we should credit people by name in commit messages when committing patches, rather than just referring to the FS number...
02:07:50JdGordonfor the first time sure, but after that there is no need?
02:08:06 Quit AndyI (Read error: 110 (Connection timed out))
02:08:15JdGordononce they are in credits task numbers should be enough...
02:08:22JdGordonbut ill change if im wrong
02:09:54linuxstbI just find it a pain to have to refer to FS tasks to see basic info on a commit like who wrote it...
02:09:57kugellinuxstb: do you mean you simplified that lcd_write_reg away?

05:47:04shelbyi know its kind of sad but i have never been so pissed in my life over how i cant charge my ipod and use it at the same time. i dont want to mount it and transfer files i want to charge it whilst listening to music. how do i go about that?
05:47:29shelbybecause whenever i plug it in it has that picture of a usb dongle and then it restarts in disk mode
05:47:35shelbyand i need it to stay in rockbox
05:47:37shelbyreally badly
05:47:42shelbyplease. any help?
05:47:44saratogai think you hold play or something
05:48:17shelbyi hold play when i plug it in?
05:48:21kugelsaratoga: hey, I've edited the ams sansa forum thread to reflect my current "progress" and problems with the buttons
05:48:50saratogamanual says menu, at least for the video, might want to check for your ipod model
05:48:57saratogakugel: ok i'll look at it now
05:49:53shelbyholding down play DOES NOT WORK
05:50:02shelbyim sorry to be such a prick... but... lol
05:50:04shelbyim a prick.
05:50:07shelbyany other suggestions?
05:50:11kugelsaratoga: also, if you read the logs, funman and me found something new regarding clocking and why r19234 broke the svn bootloader
05:50:14saratogashelby: read manual
05:50:40saratogakugel: i still haven't managed to read anything over dbop, it seems rather complicated
05:50:45shelbywhich one? there seems to be a million billion manuals scattered everywhere across the site and it would be so easy just for you to tell me whether i would waste my time doing that.
05:50:48saratogabut fortunately, GPIO should work fine for that
05:50:56saratogashelby: theres only one manual
05:51:01saratogawell one per player
05:51:11shelbyokay. where does it talk about usb charging and staying on?
05:51:17shelbynevermind. let me look.
05:51:18kugelsaratoga: but it apparently doesn't
05:51:41saratogakugel: theres only 4 DBOP pins which are not also wired to GPIO, and none are used for buttons
05:51:44shelbyi would soooooo rather not have an ipod than deal with this bull :\
05:51:48kugelfeel free to have a look at it. I couldn't get the buttons to read (seperately) with the same code just the pins swapped
05:51:59saratogalet me see what else is on GPIOD
05:52:31kugelsaratoga: the buttons work (the ones found as of now) in the bootloader, so yes, they are on gpio
05:52:48shelbyis it in the general settings section?
05:53:03kugelsaratoga: and GPIO B and C are physically connected to the GPIO ports
05:53:08saratogakugel: it could be that GPIOD is shared with something else, so your'e fighting with another driver for access to them
05:53:33kugelI'm not using GPIOD to work at all
05:53:39shelbyim pretty sure the manual dosent cover this
05:53:46kugelI'm still fighting with the buttons on GPIO B and C
05:53:56kugelto get them work in the main binary
05:54:08shelbyseriously. its not in the manual
05:54:11***Saving seen data "./dancer.seen"
05:54:38shelbysoo... does anyone have a suggestion besides the generic RTFM solution?
05:54:43kugelsaratoga: most of the SD stuff is on GPIOD, that's what I can tell you
05:55:44kugelshelby: I think you need to press a button if you don't want the ipod to reboot/show the usb connected screen.
05:55:55*shelby wonders which button
05:56:02shelbyits only *one* button, correct?
05:56:23shelbywhich i hold down as i am in the main rockbox menu roughly 1 second before i plug in the usb cable to the ipod?
05:56:29kugelshelby: I can't tell which one, since I don't have an ipod, but I'd be really surpised if it's not covered by the manual. Have you downloaded the pdf version? There you can searchin
05:56:41perrikwpshelby: read here
05:57:12saratogakugel: maybe the SD driver is putting the GPIO in some odd mode in the main build but not in bootloader?
05:57:15shelbythhaannk you perrikwp!!
05:57:23*shelby hugs perrikwp
05:57:25perrikwpyour welcome
05:57:47kugelsaratoga: As far as I know, sd driver only uses GPIOD
05:58:01kugeland again, I don't fight with D at all, only B and C
05:58:13saratogasorry didn't mean to say D
05:58:48saratogai noticed while trying to read some of the GPIO pins that I had to explicitly set and reset the direction and DBOP registers carefully otherwise they didn't work
05:58:56saratogaif you're already doing that then i have no idea
05:59:31kugelI explicitly set the DIR before reading them
06:00:00kugeland I really tried the same code for all pins. Some are read properly, but most aren't
06:00:08saratogaand AFSEL too?
06:00:25kugeland I reset after finished reading
06:01:19saratogaperhaps its a timing issue, does the main binary set any clocks not set in the bootloader?
06:01:39kugelno, the binary doesn't set up clocks. It's done in the bootloader

11:38:54bertrikamiconn, any idea where I can find it in the code?

11:50:49*domonoky wonders if rockbox mutexes need some sort of init.. the sd code just calls mutex_lock and und mutex_unlock, without initialisizing the mutex struct..

11:53:21domonokybertrik: i wonder if they dont really work right, and cause our reboot problem.. at least i can put a panic before the mutex_lock in the sd_transfer_sector, checking for reentry, and it gets called. if i put the check after the mutex, i only see the reboot.

12:03:13amiconnCan a semaphore indicate multiple states, or do I need a queue?
12:03:50jhMikeSamiconn: semaphore is counted with a min and max. waiting decreases the count, and if the count is < 0, it blocks. release increases the count.
12:04:04jhMikeS*counted with a max rather
12:04:05domonokyhm, starting playback now gives me again this lovely "not enough space in ringbuffer". But i also get a reboot, when the backlight should go off... probably more init problems ? :-)
12:04:13amiconnAh, hmm.
12:04:17daurnameyer: we have rockbox on the clip?
12:04:32*amiconn will probably use a semaphore and use a separate struct for communication
12:05:08jhMikeSamiconn: the wakeup object is really a sort of simple one-message queue with a stick flag (much less memory)
12:06:10domonokydaurn: people are working on clip and other ams-sansa targets, but its not ready.
12:06:20amiconnThis is for the libdemac dual-core split. The CPU thread will do the entropy decoding, then pass the data to the COP, which will (in the first implementation) do the filtering, prediction, and decorrelation
12:06:56amiconnIn a second step, it should allow the split to depend on the compression level, for better balancing the load
12:07:42amiconn-c1000 and -c2000 should then work as described, while -c3000 and up should only do the filtering on COP, then pass the data back to the CPU, which will do prediction and decorrelation
12:07:57jhMikeSamiconn: with a counted sem use can use it to make a blocking queue of samples. SPC uses two semaphores with a max of 2 each to block the codec if empty or the synth if full.
12:09:08amiconnWith a little more squeezing, this 2nd step will make even -c3000 usable on PP (maybe not on 5020, but on 5002 and 5022)
12:09:37bertrikdaurn, yes, a lot of stuff already works: buttons, display, rtc, battery readout, flash read/write, it boots and allows you to browse the menus, even plugins work, sound doesn't quite work yet
12:09:45jhMikeSis there squeezing possible to have -c5000 useable on imx31?
12:13:26amiconnAtm I have no idea for that
12:13:50amiconnCould the disk access use dma?
12:15:11*amiconn cannot imagine how ide dma works, be it on PC or an embedded platform...
12:15:18jhMikeSusing the SDMA controller is rather involved. I'm pretty sure we have to actually write code for that. it has no simple DMA controller. then using the ATA DMA modes is possible.
12:15:50bertrikdomonoky, I added the mutex_init in as3525-codec.c but didn't spot the missing mutex_init in ata_sd_as3525.c at the time
12:16:38jhMikeSimx31 still needs the ATA FIFO serviced by the SDMA controller when using disk DMA
12:16:40domonokywow ! i got a codec loading on m200v4 !! :-)
12:17:24bertriknice! any sound too ?
12:17:57domonokyi still have to remove some panicf to get to the sound.. :-)

12:21:24domonokybut the codecs load, and the pcm_play_dma_start is called... which is much better, then just the reboot we got yesterday.. :-)
12:21:58amiconnI mean, I know how normal dma works. But for ide dma, you set a special dma transfer mode in the disk (as opposed to pio). So I think the disk itself does the dma somehow. But how can it do that (access the host's memory)?
12:22:26amiconnIf this isn't the case, I wonder why the special dma modes even exist...
12:23:42domonokyamiconn: wouldnt this "special dma mode" just enable the dma_request and dma_request_clear lines in the disk-controller ?
12:24:35domonokyand via this request-lines, it tells the dma-controller when to transfer data to the hosts memory... at leats thats how it works on as3525..
12:25:58amiconnBut iiuc you could also use the disk's pio mode in conjunction with a dma controller, couldn't you?
12:27:09amiconn(at least if iordy is disabled)
12:27:38domonokyonly if the enabling of the dma_request lines is seperate from dma/pio mode setting... but i am not sure..
12:28:16amiconnI mean plain transfer, without checking an 'ready' lines
12:28:32amiconnPIO is pure timed transfer if iordy isn't used

12:48:47jhMikeSamiconn: What is the behavior exactly?
12:49:27amiconnWhen I switch it on, the rockbox bootloader loads rockbox, rockbox shows the splash screen for a fraction of a second, then the c200 powers down again
12:50:24amiconnI *can* make it boot after several tries when applying some tricks: Pull the microsd card, hold RIGHT during boot, and start pressing POWER again when the splash screen appears
12:50:37amiconnOnce booted, it behaves normally...
12:50:42jhMikeSonly your local build?

14:48:36funmanhum well .. the peripheral clock doesn't change with my diff so perhaps the dbop clock is based on plla ? :/ I'm lost

14:50:16funmanJdGordon: or perhaps you only need to adjust delays (kugel changed them too)
14:50:33JdGordonchanging it to CGU_DBOP = (1<<3) | (3-1); got the lcd in the bootloader
14:51:09domonokyfunman: your patch gives a garbled display in the bootloader on m200v4, but the main binary is working fine...
14:51:29funmanJdGordon: if you don't see too slow lcd operation it's good; but you might want to tweak the delays as well (for faster operation). Please concatenate your changes to my patch and post it on the report.
14:51:43funmanWe'll use incremental diff and when this works on all models we will commit
14:51:44JdGordonand in the main binary :)
14:51:53funmandomonoky: garbled how?
14:52:08JdGordonno buttons so checking for lcd updates is a bit hard
14:52:18domonokyi see a nearly black area, instead of the logo.
14:52:26funmanJdGordon: if it doesn't take 30minutes to draw a screen it's ok ^^
14:52:48funmandomonoky: same story, tweak the dbop clock and the delays
14:52:49JdGordonits noticable, maybe .25s?
14:53:14funmanJdGordon: try lowering the time in lcd_delay() / and highering the dbop clock frequency
14:53:38*JdGordon gets frustarted at the backlight turning off
14:53:53domonokyhm.. looks more like random lcd contents.. if i shutdown and reboot directly afterwards i see the old content :-)
14:53:57funmandomonoky: the difference is that set_cpu_frequency() isn't called in the bootloader I think
14:54:22kugelJdGordon, funman: I have a patch which makes the display less flickering.
14:54:58*JdGordon reckons the lcd speed isnt a big issue and buttons are more important :)
14:55:07JdGordonim not getting noticable flickering

15:03:10JdGordonfunman: we cant change the lcd delays at the different cpu speeds? no need to try to find a speed which works for all if its too hard
15:03:12kugelAlso, reading down and power together works, but when I add e.g. reading select (with the same code), no button at all works anymore
15:04:13funmanJdGordon: I don't know how hard it is, just that the Clip needed no modification. I don't know if the OF does cpu frequency change
15:04:18kugelJdGordon: I reduced the delay to x*=256 which works fine for me
15:04:53kugelI'm also unsure if we need delay at all. I think the 1.01.15 fuze firmware doesn't have such a delay function anymore
15:04:56JdGordonok, ill try that
15:05:19domonokyfunman: your patch works fine if i change the clkdiv to (3-1) in the m200v4 lcd driver

15:13:48bertrikgevaerts, you see partial packets, then nothing for some time and then more packets? I'm asking this because I can imagine that problems can also occur when a new packets pre-empts an transmission of an earlier packet still in progress.
15:14:23domonokyat least in the main-binary it works with all frequencys (as long as the debug menu cpu-frequency works already) which should be enough.. :-)

17:12:35kugelfunman: not sure why JdGordon was happy with the lcd performance. His clock is too slow on the fuze
17:12:47funmanwhat it does is use 0 -> 0x8000 as iram for the main build, and 0x10000 -> 0x30000 as a codec buffer. It also declares iramsize as 0 so codecs think they have no iram available
17:13:01funmankugel: perhaps because the hardware of fuze and e200v2 are different
17:13:22funmanhe mentioned slowness but not critical (i.e. it can wait for a later fix)
17:13:29kugelfunman: iirc it's the same controller
17:13:44funmanwhy aren't the 2 drivers merged then??

17:19:40domonokyfunman: same for me... something is not working correctly.. maybe because it calls pcm_bytes_waiting() and we return always 0 ? :-)
17:19:56kugelfunman: huh?
17:19:57*funman returns the amount of bytes not sent through the dma channel
17:20:20funmankugel: in the patch I posted : + set_cpu_frequency(CPUFREQ_DEFAULT);
17:20:36funmanreplace DEFAULT with MAX and see if your lcd driver still works
17:21:08linuxstbkugel: What makes you think it's the same controller? The register layout is different...
17:21:21domonokyfunman: so thats not why it only requests one pcm transfer... :-/
17:21:31kugelwill do
17:22:07funmanperhaps my 'chain' of transfers isn't working
17:23:36kugellinuxstb: the driver looks quite similar. I haven't looked into it detailed so I might be wrong

17:23:53bertrikgevaerts, ah yes, you're right
17:24:02funmanby the way I think we should create 2 linker scripts : 1 for targets with 2M of RAM and 1 for targets with >2M (with the codec buffer in SDRAM)
17:24:13domonokybut i would think playback should call pcm_play_dma_start multiple times, even when the dma transver doesnt work.

17:32:00kugelyou're welcome :)
17:33:00n1skugel: faster updates are always good to avoid the ui feeling sluggish, especially when playing music and not boosting
17:33:51funmanIMO we should mesure battery life reduction with higher pclk to find a good compromise
17:38:48domonokyquestion for people with knowledge over rockboxs pcm system: should pcm_play_dma_start() only play the requested size, or should it somehow use the "pcm_callback_for_more" ??
17:39:31kugeln1s: yes, but we aren't at the point we can enjoy the UI yet. As I said, that can be fixed later, for now it's only important that it works
17:39:45linuxstbdomonoky: The DMA interrupt handle will call the get_more() callback when the first DMA transfer is complete.
17:39:52domonokyat least the dma handler in pcm-coldfire looks like it uses the pcm_callback_for_more.. so we probably miss that..
17:40:39n1skugel: yes, sure getting it working ok is more important than optimization i just disagree with your statement that fast lcd is more important for video that other things :)
17:41:39kugeln1s: I just meant, for UI 12fps would be already sufficient (imho), which isn't the case for videos
17:41:54domonokylinuxstb: it gets a bit more complicated, as the dmac on as3525 only can transfer 2^11bit at once.. so we need more then 1 transfer for one "chunk"... but we really miss the callback at moment :-)
17:42:45n1skugel if you only get 12 fps that means that if something else is using 50% of the cpu you get 6 fps and if you are not boosting you would get something like 2fps

18:01:08funmanperhaps pcm_set_frequency() would be worth writing
18:07:44funmanmy source is WAV@44.1KHz but I still have problems finding the correct frequency :(
18:08:19*domonoky gets "noises" with this code, but no recognicable sound..
18:09:59funmantry with lower clock (divider == 100)
18:13:49*domonoky now gets short burst of recognicable sound, with bursts of noice in between..
18:14:10funmangetting close :)
18:16:02funmanI too get frequent noise (pops, cracks) but the major part is recognizable sound
18:16:20funmanlooks like it's too slow, but I know the rythm of this song and in fact it's too quick
18:16:47funmanperhaps we are transferring too much at a time ..
18:17:00bertrikdma_start_addr should probably be a unsigned char * instead of a void *
18:17:16funmancosmetics :)
18:23:00funmanI get something better with 1*32bits transfers ..
18:23:59funmanlots of cracks and weird sound, but it's definitely there ..
18:24:59funmanwhat are the requirements for the 'gentlemen' e-mail?
18:25:50domonokysvn-ready pcm code ? :-)
18:25:53gevaertsA mail client?
18:26:16domonokyand of course, dont forget the ladys.. :-)
18:26:33funmandomonoky: perhaps I misread the OF and it used 4*8bits transfers
18:27:22funmanmp3 doesn't decode however, perhaps it's too slow to fill the pcm buffer
18:27:34gevaertsfunman: the first one boasts about playing four seconds
18:28:17funmanmp3 is 36.81% realtime :-)
18:28:59domonokywow DMA_S4 is much better.. still some noises, but really recogniceable..
18:29:06funmanand the cpu should be maxed (248MHz)
18:29:08domonokyäh DMA_S1
18:29:18funmandomonoky: I used S1 and clock divider 44 (~5.6MHz)
18:31:09funmanperhaps a low pclk is too slow for SD transfers (or we use a too high clock divider in SD code)
18:32:42funmanwith PCLK @ 62MHz instead of 24MHz I see 168% realtime decoding speed for a mp3
18:33:27domonokyso maybe we should higher pclk again.. :-)
18:33:37*funman looks somewhere else
18:33:43funmanI want to verify SD code first
18:34:30funmanah we use maximal speed already
18:34:40funmanso I suppose yes .. we want to do that :o

19:10:02leachim6I know...that's where I found this from
19:10:29domonokybertrik: hurray ! repeating is probably from too slow encoder, and the noises from the incorrect dma_start_addr
19:12:12domonokyand perhaps the dma_size, funman said it should be >>4 after the get_more callback.
19:12:59domonokyanother change: DMA_S1 instead of DMA_S4
19:13:59bertrikI'm not familiar at all yet with the DMA controller

21:14:51zichowhat are the necessary files needed for rockbox to boot?
21:15:24linuxstbzicho: Rockbox itself needs everything in /.rockbox/. The Gigabeat's bootloader (Toshiba's code) requires the files inside /GBSYSTEM/
21:15:51linuxstbSo you need to keep both - and don't disconnect from your PC whilst reformatting, before you copy those files back.
21:16:21zichoso if i keep gbsystem and a clean .rockbox, its safe to format?
21:16:55shotofaddsgevaerts: hmm, yes on that occasion I was viewing the logf screen as I saw you mention earlier (although nothing was being output as I had not enabled it in the .c files). Try this one: (same behaviour, but USB plugged in from the menu)
21:18:39kugellinuxstb: the .o files aren't bigger. I think the main binary contains stuff twice or something
21:19:20 Quit einhirn (Read error: 110 (Connection timed out))
21:19:26linuxstbzicho: I think so... You can see some more info here -
21:20:05linuxstbkugel: As I said, I would blame the linker script - it's likely filling up the middle of your binary with zeros. But I'm not an expert on linker scripts, so can't help further.
21:20:08shotofaddsgevaerts: config-m200.h doesn't define USE_ROCKBOX_USB either, and that appeared to work most of the time. unless something has changed semi-recently...
21:20:13gevaertsshotofadds: when you connect "something" (I think in usb_core.c) calls usb_request_exclusive_ata() which sends messages to all queues telling things to back off the disk. As long as not all threads have replied you get the Not Ready replies

21:22:14kugelthat's why I suggest we put the ams sansas on the build table, so if someone with an idea stumbles upon that

21:41:29bertrikfunman, the FS patch for ams sansa playback is at
21:41:29kugelamiconn: if I know how..
21:41:49bertrikactually didn't change much except for the dma size / 4
21:43:14funmanbertrik: saratoga just told me we have to use unsigned types for /4 to be a >>2; but perhaps it's better to directly use a shift
21:43:58bertrikand size_t is signed, right?
21:44:11funmanno, ssize_t is
21:44:59amiconnfunman: Indeed using >>2 is better. If you do /4 with signed types, gcc does a shift and some postprocessing to ensure the round-towards-zero rule of the division
21:45:05bertrikI think it's not a big deal, just the difference between lsr or asr in assembly I think
21:45:12bertrikamiconn, ah ok
21:46:00amiconnE.g. (-1)/2 yields 0, while (-1)>>1 yields -1
21:47:14amiconnbertrik: It's not. For signed types, gcc does an asr followed by some extra instructions to correct the error I just illustrated

21:56:32kugeldoes it look good?
21:56:59amiconnIn the asm, I mean. Since we know that only bit 0..3 and 12..15 are connected, we don't need to duplicate the low byte if we set the correct bits from the beginning
21:57:31amiconnThe output data is composed bitwise anyway
21:57:37funmanto save 1 instruction?
21:57:58amiconnYea, why not? It's a trivial optimisation
21:58:55funmanof course

22:23:03funmanthe instruction pointer points just one instruction after the last word of wav.codec (and the alst part is the bss and "abs" so it shouldn't have been executed)

22:24:51amiconnUnhelpful: Yes, recorder firmware is compressed
22:25:16kugeloh, I read binsize is larger than actual size
22:25:45funmanabs = absolute symbols (defined in crt0.S and linker script it seems)
22:26:34amiconnThis is necessary to get around the archos loader limit (for recorders that can't be flashed, the user doesn't want to flash, or of course even for first-time installation)
