#rockbox log for 2009-10-25

00:00:16TheSeveni consider indenting them altogether ok. but not indenting them *between* the # and the ifdef
00:00:31saratogaIMO something like #IF \t \t CONDITION might be a nice compromise, so that the # is left aligned but the check is lined with the code
00:01:26TheSeven"# ifdef WHATEVER" looks very weird though
00:01:35TheSeven(and that's what I just found)
00:01:49saratoga#ifdef X>Y looks ok to me
00:02:04saratogasince you can find it easily while skimming, and then see what level it applies to

00:02:34TheSevenand in files like config.h where there are *only* preprocessor directives, I'd indent them like regular code
00:05:33SlasheriDavide-NYC: that might be bad/risky
00:06:30Davide-NYCwell I just flashed to the latest (SVN) BL without the patch and now I can only boot from ROM
00:06:30Slasheriit's a safety feature to boot from disk after having used the bootloader usb mode (if flash images are corrupt)
00:06:51Slasheriah yes, but try_flashboot should check the bootmethod before that
00:07:21Slasheriwell, it could be safe. But ideally the bootloader should be fixed to allow booting directly from CF
00:07:43bertrikTheSeven, do you configure the SDRAM controller for the nano 2g?
00:07:58Davide-NYCI agree. And I'm willing to be the test pilot (once). So if you'd like to help I'm here to test for the next 30 minutes or so.
00:08:09SlasheriDavide-NYC: that's great to hear that the svn bootloader is working
00:08:36TheSevenbertrik: No, I rely on norboot to set that up.
00:08:39Davide-NYCwell it's NOT working. Only ROM boots.
00:09:13Davide-NYCHD and RAM do not boot. In other words, SVN BL for iriver H1x0 targets is borked.
00:09:13Slasherioh.. does it give any error message when it tries to boot from the CF?
00:09:21Davide-NYCata -80
00:09:31Slasheriouch.. HD wont boot either?
00:09:45Davide-NYCI don;t have any HDDs anymore. (LOL)
00:10:06Davide-NYCI can however still boot from ROM and access the filesystem on the CFCard no problem.
00:10:21Slasheriah, ok. hmm, i have not much idea about CFs because my HD is still working :)
00:11:13SlasheriDavide-NYC: just remember to keep a working ram and rom image :)
00:11:47Davide-NYCSlasheri: Certain CF cards seem to work fine while others do not. The idea is to have the BL work with all CF cards on the market. My other (tiny) CF card give no problems.
00:11:55Slasheriso it says: "ATA error: -80"?
00:12:16Slasherihmm, interesting
00:12:26 Quit bmbl ("Bye!")
00:12:32Davide-NYCI'm going to reflash with the semi-official bootloader v7pre4
00:14:36Davide-NYCOh crap. The iriver flash utility just gave me a "NOT from ROM" error.
00:15:47SlasheriDavide-NYC: you have to boot using the RAM image
00:15:54Slasherithen it works
00:16:23Davide-NYCYeah, but with my new SVN bootloader RAM booting does not work!!!
00:16:39Slasheriouch, really? that's bad
00:16:42Davide-NYCOnly ROM. So now what?
00:16:56TheSevenDavide-NYC: Don't say you hadn't been warned. ;-)
00:17:06Davide-NYCI'm not saying anything of the sort.

00:17:35Slasheriwell, that's a little more difficult issue then..
00:17:48Slasheridid you try re-flashing the RAM image (rockbox.iriver)?
00:18:07Davide-NYCCan I do that if I boot from the ROM image?
00:18:34Slasheriah, yes! there is a way
00:18:44Slasheritry ROLO'ing directly to the rockbox.iriver
00:18:51Slasheri(short click navi on it)
00:21:04Slasheridid it work?
00:21:07Davide-NYCStrange, I was able to reflash the bootloader, but the same problem persists. I'm going to reflash the RAM image to see if that canges anything.
00:21:37Davide-NYCBoot to ROM −−> ROLO from CF −−> flash RAM −−> reboot
00:21:49Slasherihmm, interesting. maybe the ram image has become corrupted
00:22:07Davide-NYCThat's what I'm thinking
00:22:50Slasheri(but i don't think that should happen)
00:23:49Davide-NYCI also cleared all of my settings for good measure (twice)
00:24:00Slasherigreat! so the ram image stopped working immediately after flashing the new bootloader?
00:25:08Davide-NYCI had V7pre4 on there originally. CF booting to my RiData card didn't work. After flashing the BL to the current SVN image my RAM booting also failed to work.
00:25:30Davide-NYCI had today's SVN compiled with RTC flashed to both RAM and ROM.
00:25:37*Davide-NYC living on the edge!
00:26:28Slasheriok, i will have to check that. In fact re-flashing bootloader and testing ram/rom boot after that was missing from my test sequence. So it's very possible there was a bug
00:27:00SlasheriDavide-NYC: great :)
00:28:04Davide-NYCFor my other card (different brand) everything works as it should. Petur mentioned that it may be a timing issue with the different cards. (I have no clue what that actually means0
00:28:59 Quit reydarz ("CGI:IRC")
00:29:30Slasheriindeed. I was looking for ata error code -80 but couldn't find it yet, amiconn?
00:30:25Davide-NYCMaybe I just buy a Kingston Ultimate or a Sandisk Extreme III and call it a day.
00:31:03 Join T44 [0] (
00:31:26Davide-NYCOr better yet, the Kingston Elite Pro cards are even cheaper and I bet have no timing issues. Thoughts?

00:36:18saratogaI don't understand the coldfire libmad assembly
00:36:33saratogait looks like it doesn't use the same mdct algorithm as the arm assembly
00:38:14Davide-NYCSlasheri: I'm also noticing that my "HDD" light stays on my RiData unit but no on the other one.
00:40:13SlasheriDavide-NYC: i am just trying to find the correct error code.. but it looks rather hard, there may be several possible places because that -80 isn't very accurate
00:41:45Davide-NYCSlasheri: Please confirm that rockbox.iriver is the name of the bootloader. When I try to flash it from a ROLOd RB it asks if I want to reflash the RAM image.
00:41:59Slasheriok, it might be the set_features() function in ata.c where the problem occurs
00:42:11kugelSlasheri: -80 is possibly the 8th error that can happen in the storage driver (those return usually -N*20)
00:42:26saratogaunless i'm missing something the coldfire libmad mdct is much less efficient then the one used on ARM
00:42:59SlasheriDavide-NYC: that depends what target you are building
00:43:02 Join German [0] (
00:43:10Slasherinormally rockbox.iriver is the actual rockbox ram image
00:43:14Germanhallo =D
00:43:20Slasheribut when building a bootloader, it will be the bootloader
00:43:21saratogaunless maybe its unrolled somehow, it does seem to have roughly 2x the multiplications as the arm version

00:43:41Slasheri(you can determine that from the file size, bootloader is below 64 KiB)
00:43:56Davide-NYCGuys, when I compile a BL I configure (H120, BL) then I make. I end up with bootlader.bin, bootloader.elf, and rockbox.iriver.
00:44:24Slasheriyep, rockbox.iriver is the bootloader (you have to rename it to bootloader.iriver)

00:49:28Davide-NYCOK, I had originally simply overwritten my RAM file with the newer bootloaders.
00:49:43 Quit Topy44 (Read error: 110 (Connection timed out))
00:49:59Davide-NYCI guess the name of the file is what the iriver_flash utility uses to determine what the user is trying to do.
00:50:26SlasheriAlexP: that sounds good :)
00:50:51Davide-NYCNow when I try to reflash the bootloader it says "Incompatible/Untested bootloader" and it does not let me flash the BL.
00:50:52SlasheriDavide-NYC: indeed, that would explain it then
00:51:14Davide-NYCDo I need to modify the iriver_flash utility?
00:51:30Slasheriyep.. you have to override the safety check from iriver_flash.c. How did you flash the SVN version just a moment ago?
00:51:42***Saving seen data "./dancer.seen"
00:52:17Davide-NYCI never did. I only *thought* that I had tested it when in fact I only borked the RAM image.
00:52:31Davide-NYCAm I nuts to even attempt this?
00:52:33Slasheriah :D
00:52:49Slasherilets hope it works, nobody knows
00:53:12Slasheriand, be sure to keep a working rom image..
00:53:35Slasheribootloaders have some simple safety mechanism to load than rom image if bootloader fails

00:57:10Davide-NYC If I just comment out the "if (!detect_valid_bootloader(audiobuf, len))" section (to the endbrace) is that all I need to do in iriver_flash.c?

01:00:41Davide-NYCNow I can actually test the SVN bootloader. Then (if my player's not bricked) I'll test the patched version.
01:01:17Davide-NYCmake reconf
01:01:17Davide-NYC?me doh! wrong window!
01:01:17kugelit reads "audiobuf" directly? nasty stuff ;/
01:02:16Slasherikugel: well, it uses audiobuf directly for other purposes (to load the flash image in memory for flashing)
01:02:48kugelit was probably made when we didn't have a useful buffering api
01:03:29Slasheriindeed. And anyway, the number of api calls should be minimized when flashing critical code (like bootloader)
01:04:32Slasheribest way would be to disabled interrupts entirely during the flashing process
01:06:05Davide-NYCme/ Wonders if there is a way to globally remove all games and demos from the build process. Like a "lean" build...
01:06:05*Davide-NYC learns the me switch
01:06:05kugelit's impressive which powers plugins actually (could) have when looking at these old plugins
01:06:53kugelDavide-NYC: you can do make `pwd`/apps/plugins/iriver_flash.rock
01:07:11kugelto only build that and no other plugin
01:07:27Davide-NYCkugel: thanks
01:08:28AlexPDavide-NYC: If you want to do it permanently, remove the ones you don't want (or comment them out) from /apps/plugins/SOURCES
01:09:39Davide-NYCAlexP: I know that method but I compile so infrequently that I'm usually redownling the source and my patches are broken. :-P
01:10:43AlexPThe build system seems to be checking for rockbox.iriver specifically, so is erroneously being red
01:11:03AlexPIs that something I have access to, or do I need Bagder / Zagor?
01:12:58TheSevengevaerts: did you see that weird beast build?
01:13:35Davide-NYCW00t! I just flashed to the SVN build and booted from CF card!
01:13:41kugelAlexP: I *think* the error-regex is somewhere in SVN, but I'm not sure
01:14:59AlexPI think I need to change /www/buildserver/builds
01:15:04SlasheriDavide-NYC: that's great! maybe it's a time for next bootloader release :)
01:15:10AlexPBut I'm a little wary of doing it blindly
01:15:23Davide-NYCRAM boots OK.
01:16:23Davide-NYCSlasheri: the real test is if USB diskmode exits gracefully.
01:16:24kugelAlexP: m68k:nozip:h100boot:iriver H100 - Boot:rockbox.iriver:−−target=h100,−−type=b:690 to m68k:nozip:h100boot:iriver H100 - Boot:bootloader.iriver:−−target=h100,−−type=b:690 looks like the way to go
01:16:36AlexPkugel: Yes, that's what I think
01:17:26AlexPI'll try :)
01:17:32kugelif it's not right then you discovered a useless field at least :)
01:17:40AlexPIf it still moans I'll revert and wait :)

01:53:57saratogalabamiconn: coldfire mp3 is fast becaue the EMAC is fast, but the ASM code seems to do quite a few more multiplies per IMDCT then the ARM version
01:54:19pixelmamc2739: since I *believe* the M3 belongs to the latter, you wouldn't put the M3 in this \opt - but in a later one for the \opts in the columns
01:54:47amiconnsaratoga: Yes, and I'm saying that this is very likely okay, since reducing the number of multiplies there will probably make things slower
01:54:59saratogalabARM uses a fast algorithm that takes ~46 muls per 36 point IMDCT (lowest known count is about 43), whereas Coldfire seems to need more then 100
01:55:17mc2739pixelma: I see, and thats why that \\ was inside the {}, otherwise you would have a blank line at the top of the table

02:00:52kugelit was 1 day before 3.4 or so
02:01:51pixelmawhat was it?
02:01:57kugelI don't know a way to properly opt that thing. some targets that don't have this feature due to lack of buttons shouldn't have the manual entry
02:02:57AlexPkugel: If there is no existing way of doing it, you could add it to features.txt
02:03:21kugelAlexP: that would mean introducing a #define for it (there's none) ;)
02:03:23pixelmaor \(n)opt it manually by *_PAD since that's the restrictive thing
02:03:40AlexPkugel: yep, but it is that or by each individual pad
02:03:53AlexPIf it is only a few pads, that'd be better I think
02:04:07kugelI basically would like to know if it's possible to make an opt from the existence of the following command "\newcommand{\ActionWpsPlaylist}{\ButtonRec}"
02:04:45AlexPkugel: Just do \opt{pads_with_lots_of_keys}{blah}
02:05:02AlexPor \nopt{pads_with_no_keys}{blah}
02:05:09AlexPdepending on which is the bigger group
02:05:38pixelmayes, you could add this command to the platform files that have it and use it like e.g \nopt{ONDIO_PAD}{\ActionWpsPlaylist}
02:06:08pixelmalater in the table or description
02:06:41kugelhrm, that would work, I more hoped though that something like \opt{\ActionWpsPlaylist} would be possible

08:50:42amiconnYou mean the lcd controller reads from that buffer by itself?
08:53:03bertrikyes, it does master DMA to get the data
08:53:44bertrikI vaguely remember that e200 does this as well, but this has a copy step, I'll check
08:54:36amiconnYes, that copy step is needed, because the application needs a way to decide which changes go to the lcd and when
08:55:01amiconnWell, unless you have a way to control the dma

09:04:43 Join bluebrother [0] (n=dom@
09:05:20bertriksometimes is not just a single line. I've seen once that the bottom contained a kind of vertically mirrored version of the top
09:05:57tmzthave you located all the lcdc writes?
09:06:08markunbertrik: I mean the values that are written to the LCD driver over SPI, I assume you had to copy them into rockbox, right?
09:08:18bertrikthe m6 sp driver basically contains code for two separate LCDs now, I copied the controller init, lcd init/enable etc. from a reverse engineered OF
09:09:50bertrikthe weird thing is that one of the two meizu m6 drivers cannot even work in an m6 sp, because it selects the LCD driver based on an ID read back from the LCD, and the pin to read this is not even connected
09:10:19bertrikI haven't really looked at the meizu m6 sl driver yet
09:11:46bertriktmzt, yes I think I've located most of them. The OF does seem to make much more use of the special features of this LCD controller (OSD overlay for example). I'm currently only using the "background buffer"
09:12:05tmztwhat chip?
09:12:37tmztlcd controller/lcdc I mean the framebuffer registers, not lcm or driver

09:13:57bertrikthe LCD controller is part of the s5l8700 SoC and handles the framebuffer part (for example conversion of packed pixels into 24-bit RGB towards the LCD), the LCD is probably a samsung S6DXXXX type
09:15:06tmztso those are the registers I mean, the type of corruption you seem to be describing is related to that
09:15:16bertrikoh and one giant issue is that the player seems to hang after initialising the display .. :\
09:15:48tmztI believe incorrect pixclock would have different symtoms depending on lcm
09:16:12bertrikwhat do you mean by lcm?
09:16:12tmztokay, that's probably dma or EN bits of some kind
09:16:23tmztlcd control module
09:16:40tmztthe samsung s6dxxxx you were referring to
09:16:57tmztis that the part number of the lcd?
09:19:57bertrikyes I think so, the protocol for talking with the lcd (to set the gamma curve for example) is identical to the protocol used in the s6d0139
09:27:32tmztkug: I think your the one to ask, ams sansa has a two stage rockbox bootloader?
09:29:59bertrikmarkun, the "aha" moment to get this driver working was the realization that the framebuffer was located in DRAM and DRAM access has not been properly set up yet ... :)
09:31:03bertrikso setting up DRAM properly is probably the next thing I'll work on
09:31:54tmztmissing clock?

09:39:25bertrikI guess this is probably easy to locate in the OF

09:42:11bertrikyes, the SDRAM controller is part of the s5l8700 SoC
09:42:55tmztwhat is this soc? it's for mp3 players or it's more general purpose like the s3c/s5c

18:32:20bertrikI'm having trouble to really understand how the buttons are connected to the DBOP lines in the various ams sansas
18:32:31kugelI tried that, and it didn't work. without precharging it would always detect whether it's pressed or not
18:32:48*Unhelpful takes another stab at building gcc-4.4.2 :/
18:33:03bertrikOn the c200v2 for example, all buttons seem to pull down a line when pressed, but this is different apparently for the hold button on the e200v2/fuze
18:33:07bertrikkugel, so it always detected hold, or never detected hold?

18:38:59kugelIIUC this unwind stuff is only needed for non-C languages which can do advanced exception handling
18:40:06kugelI can live with that I have to have stub sections for extab/exidx, but not that unwind makes require linking against a C lib implementation
18:41:27kugelI haven't tried patching gcc to #if 0 the unwind related code though
18:41:58Unhelpfuli was discarding extab/exidx. i *believe* it was a div0 handler that pulled in the unwind stuff. i don't have the depth of knowledge to figure out where to stub out a handler to avoid the unwinding...

22:24:00kugelbertrik: I'll try the dbop patch later today. is there anything else I can test? I don't think 0xe0ff is going to work
22:27:09kugelbtw, is writing to dbop_dout safe during lcd updates? couldn't that won't that mess up the coordinates? I don't understand it fully

22:31:23bertrikkugel, the lcd only really looks at the DBOP data lines around the time a control line pulses. The control lines are disabled by the dbop read routine (and restored to their old value at the end of the dbop read routine), so this should be safe.
22:32:15bertrikIn the old situation we actually communicated with the LCD controller instead, so it was possible that a command was interrupted by the write-red-pixel command.
22:32:35bertrik(at least, that is the theory :) )
22:33:52bertrikkugel, I'm a bit out of ideas what next to try, I'd really like to get rid of the extra delay for reading the hold button on the fuze, but maybe we just can't get around that.
22:34:33bertrikOne final thing to try is to write something into bits 8-11 of the pre-charge and see if that has any effect on the hold button reading

22:40:10bertrikgreat, please put it on the wiki. The FM chip looks like another si4702 just like the clip v1, and the "SD" in the memory marking looks like a memory chip with SD card interface (which is easier to interface than a raw NAND chip)
22:40:10 Quit bmbl ("Bye!")
22:40:11mtShould I save it like that ? I wanted to double check the chips' markings but searching with any part of the marking didn't get me any good result.
22:41:01tomersCan somebody check the build server?
22:41:16tomersBuild should have been done 68m 57s ago, at 22:32:15...

22:43:53amiconnkugel: Do you have a patch for testing lcd_bitmap_transparent_part() in test_gfx somewhere?
22:44:21kugelamiconn: yea, but I noticed my tests are pretty nonsense
22:44:32*amiconn got some C code that's only 1 instruction longer than the asm; speed should be about the same, depending on the amount of transparent pixels
22:44:49 Join kyle6513 [0] (n=kyle@
22:44:58kugelor rather they only tested the loop performance, as the bitmap didn't have the transparent colors
22:45:26amiconnIf there are many transparent pixels, it should be a bit faster than the asm, if there are none or almost none, it should be a little slower (but still measurably faster than the C in current svn)

22:49:32saratogamt: so basically you're stuck waiting for a sandisk firmware update?
22:50:07mtOr way to get into recovery mode :)
22:50:21kugelwith my paste from tonight I got 68fps on my fuze (again, only the loop performance). That does not do "int i = width" and then counting towards zero because that was actually slower it (the asm version does this)
22:51:06 Join faemir [0] (n=faemir@
22:51:25saratogamt: you cuold try shorting the pins on the flash memory and see if you can get into recovery mode like the e200v2
22:52:17mtI'll look into it tonight
22:54:19kugelI think I'm gonna do better tests as I also didn't cut enough out of show_logo() (i.e. it does more stuff that just doing the lcd_bitmap_transparent() call) :/
22:55:30linuxstbMaybe choosing some different-sized bitmaps from apps/plugins/bitmaps/native/ and drawing those
23:01:57linuxstbTheSeven: Wow, that's an impressive runtime...
23:02:32TheSevenSomebody needs to do one without boosting/undervolting then
23:03:17TheSeventhe battery runtime so far is far better than expected, the ADC measurements are probably way too high because of the current the ADC itself and the CPU (which will be busy waiting during the measurement) consumes
23:04:03 Quit stoffel_ (Remote closed the connection)
23:04:11TheSevenand remember that this ipod battery is 3 years old and very heavily used, several times deep discharged, etc.
23:04:47linuxstbIs boosting/undervolting in SVN?
23:04:56TheSevenno, but in flyspray
23:05:40TheSevenIf the battery indicator is right, we'll hit ~50 hours, that's ~8mA if the battery would still have its full capacity, so probably even less!
23:05:43linuxstbI could run some tests - my Nano2G has hardly been used, apart from the last couple of months for Rockbox development.
23:06:16TheSevenif what I think right now is true, the boosting patch may almost double the run time
23:06:43TheSevenso yours is likely to end within a day at least, while i'll have to wait for another day...
23:07:44linuxstbI could try with SVN, and then again with your patch. It makes sense to do them both with the same ipod.
23:08:01bertrikTheSeven, that's a really good runtime! many targets seem to consume something on the order of 30 mA or so.
23:08:05linuxstbSo is battery bench working, or are you just watching it "manually" ?
23:08:14TheSevenlinuxstb: if you don't need your ipod, go for it!
23:08:37TheSevenit's working after some fixes like stack size increases
23:08:56TheSevenhm, the battery bench stack is probably the only one I haven't committed
23:08:59bertrikcan you turn the ADC measurement somehow in a wakeup/signal wait?
23:09:13TheSevenit's I2C
23:09:29TheSevenso i need to poll the PMU for a finished conversion
23:09:39TheSevenbut yes, i could wait a bit less busy

23:37:50Unhelpfulkugel: looking at maps from attempting to build on e200 with 4.4.1 eabi, after discarding the exception-related segments, i see references to a number of division-related (per naming convention) routines with __eabi prefixes. my guess is that the eabi compiler emits calls to different division routines than the "standard" one... perhaps aliasing these to more "normal" routines would help?
23:39:29 Quit faemir ("Leaving")
23:40:04kugelUnhelpful: maybe, remember we still need working division :/
23:40:58Unhelpfulkugel: obviously, but if we supply our own division routines with the expected names, or alias the eabi ones to "standard" ones, we can perhaps avoid the other cruft that they pull in.
23:41:01kugel__eabi_* ain't the problem, is it? the unwind relateted functions are
23:41:47kugelone should probably have a look why the eabi pulls unwind exceptions in even for C code :S
