#rockbox log for 2005-02-27

00:01:06asdsdi understand its after the string ESTFBINR, 0x220 right? but i can't seem to do the trick
00:02:01HCldoes anybody know how i can get objdump to do a raw disassembly of a file
00:02:02HCl?
00:03:17preglowHCl: raw, like disregard object file format?
00:03:31HClyea.
00:03:39HCljust direct opcodes in a file
00:03:46HClcause thats what my dynarec is making..
00:04:46HClany idea? :/

00:14:56*HCl sighs.
00:15:08*HCl *just* needs a way to disassemble some stuff -.-;
00:15:35preglowHCl: send it to me, i'll try pushing it through ida
00:16:43HCldoes ida have a coldfire mode?
00:16:50preglowyes
00:16:56HClby defaul
00:16:58HClt?
00:18:03preglowshould so
00:18:07XShocKyes, ida has coldfire support initially, full version, not dempo

00:25:36HClmmm, let me try this link...
00:26:30preglowok
00:26:37preglowi've got a bunch of clrs
00:26:54HClyea, that should be correct
00:26:57HClclrs into memory..
00:27:07preglowand a movea with a 0xff.. address, now that's a dead giveaway :)
00:27:21HClm?
00:28:02asdsdman when i opened the unencrypted hex file with a hex editor i thought it was gonna be as easy as opening up a w32 exe
00:28:26preglowhttp://glow.m0f0.net/rockbox/test.s
00:28:28asdsdi guess work still needs to be done to figure out the structure of the firmware and stuff, thats just too much for me
00:28:30preglowdoes that look familiar?
00:28:51asdsdnice
00:28:52markunI just turned on the greyscale mode on the iriver. It looks funny :) The text has half the hight and the bottom half of the screen has some random pixels.
00:28:57asdsdwhats C:\dyna_0x150?
00:29:05preglowthat's the disassembled file
00:29:08asdsdof what
00:29:09HClmarkun: nice.
00:29:40markunThe fonts even look kinda anti-aliased :)
00:29:48asdsdwhat were u able to disassemble?

00:43:58asdsdwouldn't happen to be linus torvald would he?
00:44:26amiconnno
00:44:48asdsddidn't think so
00:46:12XShocKif he was, then rockbox would be UNIXbox. :)
00:46:28amiconnNo, Linuxbox ;)
00:47:54XShocKI suspect Torvalds works in ipodLinux.
00:48:20asdsddamn
00:48:26asdsdive seen a screenshot of ipod running linux
00:48:29asdsdlooks funny
00:51:34HCli don't understand whats wrong with my peas
00:53:46markunHm, now I only need a plan how to use greyscale in rockbox.. Maybe I first should get everything to look the same as before.
00:53:55 Quit midk ("Leaving")
00:54:09HClmarkun: i'd say update the lcd_drivers to still work regardless of the colormode
00:54:32HCland add a drawpixel that allows you to set the pixel value

00:56:54HCladdq.l #8,d7 = WRONG, should be a7 aka sp
00:56:55HCl :)
00:57:26asdsdhey lets say someone were to donate like 20 thousand dollars, do u think like the speed of the project would increase?
00:58:24HClif you want my honest opinion
00:58:26HClno.
00:58:38HClsince people are already spending most of their free time on development
00:58:49HClextra money wouldn't help with creating more free time
00:59:10XShocKit will stop, work is not compatible with big amounts of beer.
00:59:18HCl :P
00:59:26*HCl smacks himself upside the head
00:59:38HClvalue|=0x8; ! not value |=0x4
01:00
01:00:12HClno wonder it crashed if the stack pointer was all off.
01:01:16***Saving seen data "./dancer.seen"
01:01:25HCloh, can someone with cvs access take a look at my patches for sokoban and snake and possibly commit them so they can be removed from the todo list?
01:01:33asdsdso its not a money problem
01:01:54asdsdbut wouldn't u guys be able to hire like high quality engineers with 20K?
01:02:03asdsdand u can all afford plenty of h320s and h120s
01:02:22HClwell. it might speed up the development for h320s
01:02:34HClsince as far as i know none of the core coders have access to one of those
01:03:34asdsdah-man
01:03:49HClcan anyone here confirm that pea is *the* way to push values onto the stack?
01:03:58asdsdoh yeah and then all u guys would be able to receive a hardware debugger right?
01:04:15asdsdwell pea is push effective address right?, sounds right to me
01:04:17HClwell, i suppose that would indeed help some people, if there were more bdms
01:04:38HCli know i'd have less of a hard time debugging rockboy
01:04:42HClbut we want a gdb stub anyways
01:04:47HClwhich is both cheaper and nicer
01:04:55asdsdgreat hcl, so its settled ill start a fundraiser tommorow washing cars and selling cookies and ill donate 20k
01:05:01HCl :P
01:05:04HClwell, what would help
01:05:19HClif if you keep most of the 20k, and spend part of it on an engineer who'll make us a coldfire gdb stub
01:05:23HCl :P
01:05:24asdsdwhats a gdb stub?
01:05:40HClits a small program that allows gdb to remote debug the iriver
01:05:50HClthrough the serial port thats on the pcb
01:06:08asdsdoh i see
01:06:12asdsdhey that wud be pretty useful
01:06:24HClyes
01:06:34HClcause then everyone would have an fairly easy way to debug
01:06:52HCl(all you need to do is open up your iriver, solder or otherwise attach two wires to the serial port, hook it into your serial port
01:07:01HClas far as i know anyways
01:07:04HCli'm not a hardware person
01:07:16amiconnGrmpf.
01:07:26amiconnThis darn simulator drives me crazy :(
01:07:32HCl :/
01:07:44*HCl hands amiconn a hammer and a magnet "threaten it with this"
01:08:05HClcomputers are scared of magnets *nods*
01:08:17amiconnWhy the **** does the X11 simulator not seek correctly in a file, while the win32 simulator does ??!???
01:08:47amiconnOn the other side, the codecs work in the X11 sim, and they don't in win32
01:09:02HCldon't forget rockboy
01:09:23amiconnCould please someone with a real Linux (or other unix) box try my test plugin, and tell me whether it works in the x11 sim?
01:09:56HClwell, i can run it through vnc.. but i want to get this dynarec block to work first..

01:10:13prethomdamn it to hell
01:10:55amiconnIt does a somewhat silly thing - it writes a test file while lots of 'A', 'B' and 'C' and one 'X', but with seeking in between. If it does it correctly, the file should be 15 KB.
01:11:21amiconnMy X11 sim makes a file 25 KB + 1 byte....

01:13:16prethomgreat
01:13:22le915u guys ever consider making rockbox for the Dell DJ?
01:13:45HClhmmm...
01:13:50le915the Gen1
01:14:02HClcan anyone confirm that move.l d0,-(sp) is the correct way to push a register onto the stack?
01:14:05asdsdspeaking of alternate mp3 players
01:14:09le915noone has done anything with the dell yet, and its bumming me out
01:14:30asdsdis there a rockbox-ish project going on for the ipods? thats not linux?
01:14:35prethomHCl: it is
01:14:38le915i hate ipods
01:14:40HClprethom: thanks
01:14:47le915irives kick butt though
01:14:47asdsdi do too, but i was just curious
01:14:49prethomHCl: at least it should work
01:14:57HClyea, its my current encoding of a push
01:15:03HCli think my assembly looks semi correct now
01:15:13le915would it be hard for them to port rockbox to the dell DJ?
01:15:28prethomle915: wouldn't know until we see some hardware specs
01:15:35le915o
01:15:50le915i could get em for ya if you like
01:16:19prethomi'm not really interested, i've got my hands full with h120
01:16:32asdsdso is there an rockbox-ish project going on for the ipod?

01:19:17le915just load em to the HD?
01:19:43prethomle915: with a bit of luck, you just load them onto the hd, and then select them like any other file
01:19:48prethomle915: rockboy should load
01:20:02prethomassumes you've the viewer list set up correctly
01:20:12le915what would happen if i loaded your stuff on my mp3 player, would it kill it?
01:20:14le915:)
01:20:18amiconnhahaha :( With the old build system, it's the other way 'round. The X11 sim seeks correctly, while the win32 sim doesn't work at all (can't open file) . The latter was expected though...
01:20:20HClum.
01:20:48HClthere is no working build of rockboy from my side at the moment.
01:20:51prethomamiconn: sounds like you've got yourself some fun there
01:21:33amiconnI don't really consider this fun; I simply want these simulators to work, so I can test rockboy on them :(

01:25:27amiconnI don't use any 64 bit thingies. It's a plain simple file operations test
01:25:36prethomok
01:25:45prethomjust give me simple directions
01:26:11amiconnThere's something wrong with the file ops in the X11 sim, and I want to figure whether it's just cygwin or a problem with the new sim build system

01:27:29amiconnHCl ??
01:27:31prethomamiconn: but ok, just try a plain x11 sim build?
01:27:55amiconnprethom: It's a single plugin. Simply add that to apps/plugins/SOURCES, compile & run in the X11 sim. It should create a file in the archos/ dir

01:31:46HClmemory accesses are really expensive at the moment
01:31:47amiconnI mean, without the complete implementation...
01:31:58amiconnprethom: Missing libs?
01:32:10HClwell, ofcourse i haven't implemented all the possible optimization yet
01:32:20HClin the end, it should be faster. i'm mostly worried about the slow ram of the iriver

01:32:39HClpeople make it seem that way

01:32:42asdsdhey i got an idea, how about with the 20k i raise i bribe some of the iriver core engineers to help the rockbox project
01:32:58amiconnThe archos has fast page mode ram. Accesses are 1 cycle as long as the page is open

02:06:03prethomwhy should they be smaller?

02:08:00prethomwell, compare symbols
02:08:38prethomsomewhere something has to be bigger

04:43:19ashridahit's going to be emulation either way
04:43:24ashridahit's just a method of getting better performance

07:11:19asdsdwouldn't it be slower if it has to dynamically recompile the rom to run it in a faster way? rather than just run it in the slow way?
07:13:48ashridahasdsd: it's a balance, certainly.
07:15:05ashridahthe idea is that if you recompile a piece of code once, then rerun it a few thousand times a second (for, say, drawing to the screen), you save, so you identify common often used routines and have the dynarec code replace them with faster hardware specific variants
07:15:15ashridahthe exact approach depends a lot on the original code

07:15:45HClflatmates with the iq of a caveman suck -.-
07:15:53ashridahif i recall earlier conversations, nintendo gave developers a common library to use, and replacing the common code in the library will be a general optimisation that always works. i'm not sure if this is the case for the gameboy tho

08:47:29HClyes, well, i want it to optimize O.o;
08:47:46HClcause my implementation of the same code would be far less effecient

08:49:30amiconnashridah: That's the strangeness of gcc: Sometimes it generates ultra-cleverly optimised code, and in other places it uses plain stupid code that's easily optimised to double speed by hand. That's my own observation, with -O1 on sh

09:51:28amiconnImho the speed won't change
09:52:36markunamiconn: I now made lcd_drawpixel_color(x,y,c). You told me once not to do this, should we have lcd_set_color(c) and lcd_drawpixel(x,y)?
09:53:35amiconnWe need to keep an eye on size (not specifically for iriver, but for archos and maybe others)
09:54:08amiconnMy suggestion is still to have some drawing states, and a foreground and background "colour"
09:54:38 Join R3nTiL [0] (~zorroz@83.69.98.15)
09:55:14amiconnThis is also adaptable to b&w, and will imho even produce smaller binaries
09:56:23amiconnLook at the grayscale lib. This has 4 drawing modes, draw_foreground, draw_background, draw_solid and draw_inverse
09:56:53amiconndraw_foreground and draw_solid are identical for single pixels, they draw the pixel in the foreground colour
09:57:04markunok, so draw_background is like draw_clear
09:57:28amiconndraw_background draws the pixel in the background colour, and draw_inverse does a bitwise invert
09:58:20amiconndraw_background is like today's clear_* routines for b&w, as long as we consider the 2 "colours" as fixed
09:58:35markunI will have a closer look at your grayscale lib.
09:58:41amiconni.e. foreground = black and background = white
09:58:59amiconnThe grayscale lib allows you to set these individually
09:59:45amiconnThe differentiation between draw_foreground and draw_solid becomes clear when you look into fonr drawing

10:00
10:00:03markunAnother thing: lcd_bitmap is now implemented using draw_pixel. It's very slow. I can make a lcd_bitmap_2bit (or something) which is just like the old lcd_bitmap.
10:01:14amiconnWe still need to process 1 bit input bitmaps. So for displays with > 1 bit, imho we need 2 routines. Again, the grayscale lib example:
10:01:57amiconnThere is gray_draw_bitmap(), which draws an 1-bit bitmap, using the selected foreground and background colours and the draw mode
10:02:47amiconnThen there is gray_draw_graymap, which draws a full grayscale bitmap, i.e. the source bitmap uses 1 byte per pixel
10:04:42amiconnBoth routines should of course be optimised for the actual lcd, imho this is why Linus decided to use a separate lcd driver file for iriver (planning for 2-bit support)
10:06:19markunlooking ahaid: if we ever want anti-aliased fonts on iriver it would be more efficient to have a draw_graymap that expects 2-bit bitmaps.
10:06:34 Quit R3nTiL ()
10:06:42markunahead..
10:07:36amiconnI'm still unsure whether anti-aliased fonts make sense on a mobile unit, but if we go for it, I'd suggest to use a more universal format, i.e. 1 byte/pixel
10:08:17markunThat would make for very large fonts of cource. But during the loading of the font we could convert the bitmaps of course.
10:08:23amiconn(Thinking further ahead, e.g. gmini 220 has 4-bit greyscale, iRiver H3xx even has colour
10:09:00midkmethangas.
10:09:14methangasyes?
10:09:46amiconnmarkun: A propos large fonts: iirc you were working on unicode support. How much binary size does that add?

10:10:35*HCl sighs.
10:10:41HClthis gcc code *cant* be correct :(
10:10:50markunIt depends what the difference between the first and the last char code in the font is. max_bitmap_size * (last_char - first_char)
10:11:21markunYes, I looked a bit at font caching, but I am still thinking of the best way to do it.
10:11:26amiconnNo, I don't mean the font size, I mean code size

10:24:41markunok, no problem.
10:32:23amiconnHmm. The unicode patch makes utf-8 default, correct? That means, the .lang files need to be converted to utf-8, and we'd need a new convbfd tool thta creates unicode font?
10:33:34amiconnOf course lcd-recorder.h and the player lcd handling also needs attention
10:33:58markunYes, UTF-8 is default now. convbfd still works for latin1 and unicode fonts.

10:56:48markunHi LinusN
10:57:33LinusNhey ho
10:59:07markunLinusN: I wrote you an email about my cross compiler problem on FreeBSD. Did you get it? I'm not in a hurry to get it fixed, so if you don't have time it's no problem.
10:59:30markunamiconn: did it compile?
10:59:41amiconnNo, not yet.
11:00
11:00:00amiconnNow it does... there are warnings though
11:00:53markunYes, I know. The compiler is not happy the way I use const trings.. or are there more warnings?
11:01:26***Saving seen data "./dancer.seen"
11:01:42amiconn4 warnings about discarding qualifiers (const)
11:02:35markunI have some commented out code in unicode.h where I tried to fix those warnings.
11:02:39amiconnUnicode support adds 500 bytes so far. Not bad.
11:03:04markunfont caching will add some more..
11:03:11amiconnYes of course.
11:03:32amiconnIt looks that this is manageable for the archos too
11:04:26LinusNmarkun: i had the same problem once with cygwin
11:04:46LinusNbut i don't have a clean solution for it
11:04:50amiconnmarkun: Wow, this really eats buffer space
11:05:57markunLinusN: well, for now it compiles and works (at least on iriver)
11:06:03markunamiconn: Does it eat too much?
11:07:19markunamiconn: did the russian language file work?
11:07:32amiconnHmm, no it doesn't :(
11:07:50amiconnThe menus are all empty, I need to navigate blindly...
11:08:01markunStrange. Did you load the font?
11:08:16amiconnyup
11:08:49markunLet me check here..
11:12:10markunI now get: Language /russian-utf8.lng too large: 7000
11:12:27markunMaybe that's the problem?
11:18:56markunIn apps/language.h you need to change MAX_LANGUAGE_SIZE to something bigger than the russian.lng file.
11:19:31markunI had to do a make clean to get it working.
11:21:39 Part LinusN
11:22:47amiconnI did a fresh build, and the .lng actually loaded.

11:23:28_aLFhi
11:23:37amiconnOtherwise I wouldn't have gotten an empty menu. Reloading english.lng or deutsch.lng restores everything back to normal
11:25:27amiconnThe utf-8 handling itself seems to have problems. Maybe I copied something wrong from lcd-h100.c
11:29:07amiconnHmm. It looks just right...
11:33:38markunCould you still see the files on your archos?
11:34:46amiconnyes.
11:35:23markunCan you put a russian file on it?
11:36:59markunThe textviewer now also only displays utf-8 text, so you could test it with that as well..
11:43:00amiconnGotta run... sorry, later :)

13:07:48amiconnAny news?
13:08:25markunno news. I'm trying to study a bit.
13:10:15markunBut it's hard with all these rockbox ideas in my head.
13:10:35preglowno shit
13:10:53amiconnHmm. I'll try a cyrillic filename. Just need a method to create one
13:11:15markunCan I send you one over irc?
13:11:38amiconnI think this won't work. Irc doesn't handle unicode...
13:12:05preglowit does if both ends use utf8 charset :P
13:12:18preglowirc is charset agnostic
13:12:24amiconnYeah... but windows uses utf-16 for filenames
13:12:27markunI do, do you amiconn?
13:12:48preglowwindows uses ucs16, not utf
13:13:55markunucs-2, no?
13:14:02preglowahh, yes
13:14:42markunI used the UTF-16 decoder to convert the fat filenames. Also works with UCS-2 of course.
13:15:51markunamiconn: do you have the textviewer? I can send you a file with some utf-8 in it.
13:16:02*preglow pats utf-8
13:16:20amiconnDoes the textviewer need any change? I guess not...
13:16:40preglowamiconn: have you looked at the proportional font support patch some guy sent?
13:17:14amiconnNo...
13:17:41amiconnI won't do any major commit until I have those simulators working.
13:19:30markunamiconn: No, textviewer works without changes.
13:20:04amiconnNow I have a file with a russian name...
13:20:22markunI also sent you a unicode.txt file
13:20:35amiconnHmm. All cyrillic characters show up as spaces....
13:20:42markun:(
13:20:49markunThe font did change?
13:21:01amiconnAh, I forgot something...
13:21:37amiconnHmm, it's the same with the font you sent me :(
13:22:50markunWhere could it go wrong? Decoding in fat.c or displaying or font loading?
13:22:54amiconnOoops, this font can't be loaded completely. It's 147 KB
13:23:06markunAh, I sent the wrong one?
13:23:16amiconn6x10.fnt: 147 KB
13:23:27markunI'll send you the right one..
13:24:34markunWhat version of 5x8 did I send? Also without -stripped?
13:25:11amiconn5x8 is stripped, and works for file names
13:25:39markunGreat, than it's probably just updating MAX_LANGUAGE_SIZE in language.c
13:25:56markunHope your archos has any memory left..
13:26:01amiconnNew 6x10 works too.
13:26:10markungreat, and the unicode.txt?
13:26:43amiconnHmm. deutsch.lang needs to be utf-8 converted too in order to work.
13:26:53markunYes, of course.

13:28:58lImbushi all
13:29:16markunI send a new deutsch.lng
13:29:17rasheramiconn: dansk?
13:29:25markunIt's small enough
13:29:45markununicode is fun :)
13:29:51lImbuswow. a thousand never heard nicknames in here :-)
13:30:11Sucka:D
13:30:12amiconnrasher: I guess all .lang files need to be converted, except english.lang perhaps
13:31:06markunamiconn: Did you try deutsch-utf8.lng?
13:31:08amiconnmarkun: With the correct font, russian menus work partly. How much do I need to increase MAX_LANGUAGE_SIZE?
13:32:04markunWell, russian.lng is about 10KB, I put it to 20KB on my iriver, but you could use less.
13:32:04lImbusamiconn: I see the 2.5-release is overdue if rockbox still wants to issue new versions every second month.
13:32:35amiconndeutsch-utf8.lng works, although I see some other places need adjustment to unicode
13:32:41lImbusI don't know how far multivolume and hotswap is going, but I think the tag database is worth a new version-
13:32:56markunReally? What kind of adjustments?
13:33:17amiconnThere is the recorder button bar, and the F1 text "Menü" is no longer centered.
13:34:15markunmaybe it uses strlen?
13:35:24amiconnYes it does.
13:35:38amiconnapps/status.c, line 297
13:35:49amiconntext_width = fw * strlen(caption);
13:36:03amiconnThis is of course wrong with unicode
13:36:18amiconnI suspect more such places, e.g. the recorder quickscreens
13:36:50markunIt should use lcd_getstringsize
13:37:09markunAlso because of variable-width fonts.
13:37:10amiconnThis is a bit dirty anyway, since it assumes no-proportional font
13:37:26markun:)
13:37:38amiconnHowever, the builtin default font is fixed width for good reasons
13:38:16amiconnIt is used in a few other places in a way that assumes fixed width, and would need significantly more code for proportional support
13:38:32amiconnOne such example is the virtual keyboard
13:38:53markunWhat will the virtial unicode keyboard look like? :)
13:39:08amiconnYeah... that's a real problem
13:41:35markunI wonder what a chinese keyboard look like..
13:41:36amiconnOoops... the credits list also needs utf-8 conversion. Otherwise Björn might not agree to add unicode support ;)
13:43:06markunamiconn, do you know yudit, the unicode editor?
13:43:18amiconnNo.
13:44:06amiconnI guess that we need a configuration file for the keyboad, depending on language
13:44:46markunIt has a lot of input-methods. Select japanese for example and type in konnichiwa and there you have your japanese text..
13:45:52markunamiconn: The textviewer also needs some charset translation routines, or should we forse everyone to use UTF-8 text files? :)
13:46:41amiconnAgreed. I'd think most western text files still use latin1.
13:46:57markununicode.c has a latin2utf8
13:47:18amiconnHowever, that'd mean to make it configurable, or add some kind of auto-detection (if at all possible)
13:47:19markunno, it's called latin1encode
13:47:57markunCheck the first x bytes. If it contains invalid UTF-8 chars switch to latin1..
13:48:04amiconnutf-16 can be auto detected by the endian marker, but what about utf-8? I'm not that much into unicode details...
13:48:43markunIt can be detected. No problem.
13:49:06amiconnBut I agree that unicode support in rockbox is definitely a move forward, and that utf-8 is the way to go.
13:49:11markunBut if you have a lot of ascii and the latin1 stuff is at the end of the text we have a problem..
13:50:23amiconnIt still needs some work though, as it has to work with all units. The archos recorders are not the biggest problem, they just need some font caching.
13:51:05amiconnFont caching will be necessary anyway for languages with a big glyph range, like chinese
13:52:02amiconnThe players are a bit harder, since they should also handle unicode as far as possible.
13:52:34preglowso you have to redefine the display font on the fly? :/
13:52:49amiconnThe player lcd code already does this
13:53:25amiconnHowever, it's not possible to show only redefined chars - there are only 8 (or even 4 with the old lcd)
13:53:50amiconnIt uses some very clever dynamic remapping & replacing
13:54:44amiconnOf course it will never handle the full unicode range, but I think it's possible to handle at least latin-1 (as now) plus cyrillic and greek to some extent
13:55:17preglowahh
13:55:24markungreek with only 4 or 8 chars to redefine will look a bit strange. But with some practice it's probably readable :)
13:55:27preglowi've got a lcd just like that
13:55:44amiconnThere are some greek chars already defined
13:55:55preglowseems like most lcds are pretty similar
13:56:43amiconnThe plus side is that although only 8 chars can be redefined, the whole lcd can only show 22 chars (2 lines 11 chars each), so 8 out of 22 isn't too bad
13:57:03markuntrue
13:57:04preglowahh, it's that small
13:57:07amiconnPlus, I intend to exploit similarities.
13:57:08preglowmine is 8x16
13:57:11preglowehh
13:57:12preglow2x16
13:57:36*markun goes back to study
13:57:56amiconnE.g. "H" is the usual latin capital h, as well as the greek capital eta and the cyrillic capital en

14:06:10preglowhow old are those models?
14:07:05amiconnHow do you mean? The players itself?
14:07:45amiconnThey are out of production for quite some time. Iirc the first ones were sold in 2000, but you can still buy them new at some places.
14:08:00preglowyes
14:08:08amiconn(New as in unused and in original package)
14:09:23preglowhow does the driver handle it if there are not enough free user-definable characters to show what's needed?
14:09:57amiconnThis is explained in the mentioned page. It shows a replacement char instead.
14:10:32CoCoLUShttp://www.engadget.com/entry/1234000983033519/
14:10:33CoCoLUSwow :)
14:10:40amiconnThe characters are prioritised, so a more critical char or one with an especially ugly replacement can get priority
14:11:19preglowCoCoLUS: yeah, i saw, i'm just waiting for my box to be slashdoted :P
14:18:21preglowoh well, i prefer non-charcell based design

14:19:04amiconnIt's still easier that this dreaded x11 simulator issue on cygwin
14:19:20amiconnlseek() simply returns with -1 and doesn't do what it should
14:19:31preglowhahah
14:19:38preglowi saw you commited a NOCYGWIN patch
14:19:41preglowwhat did that do?
14:20:03amiconnIt removed the NOCYGWIN define for the X11 simulator
14:22:21preglowwell, yes, but what does that do? :P
14:23:21amiconnThe NOCYGWIN define is, together with the -mno-cygwin machine option, a hint for the cygwin gcc to generate code that can run without cygwin1.dll
14:24:00amiconnIt generates a little bit larger binaries that are a bit less posix compatible.
14:24:22amiconnThis makes no sense for the X11 simulator on cygwin, because X11 needs the cygwin X11 server anyway
14:32:07webmindhm question: on what irivers does rockbox work ?

18:10:03HCl (0x20 & (b ^ b ^ c) << 1)) |
18:10:03HCl ((2*b)&0x10)>>4);
18:10:15HClfirst line = zero flag, second line = halfcarry, last = carry
18:10:53HCland i seriously don't see that if you andi the flag register with 0x81
18:10:59HClhow you possibly could get a correct result
18:11:09HCli must be missing something vital
18:11:37preglowi'd do this by hand, where i you
18:11:54HCli was doing that.. but it was getting complicated and very inefficient...
18:11:59preglowas i said, it does not seem that gcc produces optimal code for coldfire
18:12:30preglowwell, studying optimized compiler output is complicated as well
18:12:34HClwell, i'm not talking about optimal... more about correctness...

18:13:14Chamoisxshoxk : news about recording ?
18:13:24preglowyou do know you can make gcc spit out asm, yes?
18:13:29preglowit's clearer than using objdump

18:13:38HClxD
18:13:41preglow-S
18:13:47HCli knew that, i just didn't think of it, and i don't know the flag for it
18:13:48HClwhat is it

18:16:11HClit creates test.s, but its empty
18:17:17preglowit should work, damn it!"¤
18:17:21preglowi use it all the time
18:18:38preglowperhaps you use another flag that doesn't go well with it
18:19:29preglowwhat does halfcarry flag do?
18:19:56HCli'm not even sure about that
18:20:03HCli *believe* its a carry flag of the lower 4 bits
18:20:10preglowhah
18:20:12preglowahh <-
18:20:15preglowmakes sense
18:21:37muesli-what is the idea for buffering? i mean, does rockbox buffers as long as there is free memory or does it care about those 32mb ram-module? i am thinking about exchanging the ram-module with a bigger one
18:22:10preglowHCl: but simple enough, reading compiler optimized code is a nightmare, why don't you just try it out on the player?
18:23:24HClok
18:23:30HCli think i got something more useful
18:23:36HCl0xA1
18:24:00preglowb ^ b ^ c ?
18:24:13preglowisn't b^b zero ?
18:24:14HClthat looks correct aside from the carry still being broken
18:24:21HClat least the halfcarry could work in theory now
18:24:29HClsince its not anding them away
18:25:01HClafk food
18:26:15XShocKpreglow: b^b is zero. and zero^c is c
18:26:26preglowyes
18:26:45preglowjust found it relatively pointless to write b ^ b ^ c, heh
18:26:57XShocKmmm.. yes. :)
18:33:43HClyea, its just cause its a particular case of an algorithm
18:34:12XShocKis server rockbox.org down?
18:34:40preglowdoesn't answer, at least
18:35:10HClah. and there is my bug.

21:22:03jypnoooooooo
21:22:08jyp;p
21:22:19*jyp shuts off
21:22:21willkill4foodbut i have an archos multimedia jukebox, and I was wondering if anyone had one also and if they got any of the rockbox firmware to work on it?
21:22:37jypgmini400 ?
21:23:26willkill4foodhttp://archos.com/download/pictures/picts/archos_jbm_20.png
21:23:41willkill4foodlittle bit of a big pic, but thats what I have
21:23:57lImbusthe archos multimedia jukeboxes are based on a totally different hardware. no rockbox for that :-/
21:24:26preglowmaster designers the archos people are not
21:24:38lImbuseheh
21:24:56lImbusat least it can be hacked :-)
21:26:34willkill4foodare they really that different?
21:26:49lImbusdunno
21:27:09lImbusI think, because the existing archos-jukebox and recorder have a far to slow processor
21:27:17lImbusI think so...
21:28:05jypopen it up & tell us ;)
21:28:06preglowi think i've seen it mentioned they're completely different inside, yes
21:28:27lImbusIf you are handy with electronics, open the box, make some pictures (or scans) of the hardware, start identifying the components, and start a rockbox-port to these devices
21:28:30willkill4foodi already did open it up
21:28:38willkill4foodtrying to fix the headphone port
21:28:41jypso, what's the cpu?
21:28:54willkill4foodbut the headphone port is soddered to the base if i remember right
21:28:57willkill4foodi didnt check the cpu
21:29:03willkill4foodthe HD was in the way if I remember right
21:39:24willkill4foodi think my jukebox is more or less like the recorder v2 and the fm recorder because im pretty sure they are about the same thing, but i cant find documentation of those two on the archos site very well
21:40:37lImbusthe fm recorder and recorder v2 have a 12 MHz-Cpu. No way of doing anything of the things your mm-jukemox does
21:40:56lImbuss/jukemox/jukebox
21:41:06willkill4foodwell it probably does have a faster cpu and it does have a 16mb buffer
21:41:42willkill4foodim gonna go try to figure it out, ill be back when i know what exactly is special about my jbm
21:42:04lImbusmost probably it has a cpu that is able to do the decoding in software
21:42:11einhirn(isn't 16Mb more than sh1 can do?)
21:42:25lImbusno idea
21:42:45einhirnI think I read so when browsing about 8Mb Patch...

23:08:07*HCl sighs
23:10:06*preglow makes coffee
23:12:40HClgcc must have serious bugs.
23:16:10*einhirn yells Yippeeee!
23:16:18HClm?
23:16:20einhirnMy rockbox lives again...
23:16:26HClgrats...
23:16:32*amiconn despairs
23:16:36HClsup amiconn?
23:16:40*HCl joins the despairing.
23:17:16HCl c = FN | (d&0xFF) ? 0 : FZ | (FH & ((a ^ b ^ (d&0xFF)) << 1)) | ((un8)(-(char)((d&0xFF00)>>8)) << 4);
23:17:24fuzzieLooks fun.
23:17:30HClanyone who can give me a clean m68k assembly equivalent of that
23:17:32HClgets a cookie
23:17:33HCl :/
23:17:43amiconnlseek(4, 5120, 0) -> -1
23:17:48HCland the satisfaction of having helped rockboy another step forward
23:17:51einhirn(Before the weekend I had a go to fix the GND-Problem and then a short circuit from nowhere. It's gone to nowhere again now ;=) )
23:17:53*muesli- hands out a second brain ;)
23:18:15HClgiven an unsigned char a, b, and unsigned short d
23:18:22einhirnHCl: Whoopee...
23:19:05msthmmm.. does a filesystem dump beginning with ``AFI'' (0x41 0x46 0x49) sound familiar to anyone?
23:20:48*HCl flops on the floor and sighs.
23:21:17prpplaguemst: not me
23:21:59amiconnI simply don't get it, and there seems no way to read errno correctly within rockbox...
23:24:51prpplaguemst: a quick grep of the linux source tree doesn't yield anything
23:25:50mstprpplague, yeap. Not a *nix filesystem. Some sort of flash memory image.
23:26:11mstit has a FS header and file index starting at 0x0, and data at 0x1000
23:26:31 Part thread ("out")
23:26:34mst(the destination device that runs it is apparently Sigmatel-based)
23:27:15prpplaguemst: which platform is this?
23:28:33prpplagueHCl: let me ask a stupid question, why can't you put that in a .c and use a cross-assembler?
23:29:29prpplaguesorry cross-compiler

23:31:41preglowhe's around
23:32:10nobbyk
23:32:34preglowyou'll just have to pull him from the brink of despair, and he'll probably respond ;)
23:33:12nobbyoh
23:33:15nobby:S
23:33:35nobbyhow does one go about pulling HCl from the brink of despair?
23:34:54preglow21:20 < HCl> ftp://titania.student.utwente.nl/rockbox.zip - should contain rockbox with a working rockboy
23:35:36nobbyah
23:35:44nobbytime traveling brink pulling
23:35:44nobbythanks
23:36:39mstprpplague, it's not a platform, it's a nameless mp3 player I bought and I fail to track it down - there's this whole OEM conspiracy thing, apparently the device has like 300 different OEM brands and zillions of various firmwares
23:37:52nobbytry them all and see whats good :)
23:38:43prpplaguemst: ahh
23:38:54prpplaguemst: which processor?
23:39:55mstprpplague, my suspect is STMP3400
23:40:00mstI didnt unscrew it yet ;)
