00:17 < cmwslw> anyone know where the 2g clickwheel driver is in the rockbox svn?
00:17 < cmwslw> the svn is confusing to me
00:28 < slck> i have a guess, but i'm pretty sure it's wrong
00:29 < cmwslw> any guess is good
00:29 < cmwslw> i can find the s5l8700 specific part, but.. gah so confusing
00:33 < slck> it's not as easy as i thought in first place ...
00:35 < slck> so .. you're porting some code from rockbox to embios, then porting another pieces of code back?
00:35 < slck> or i get it wrong?
00:36 < cmwslw> well i want to write a clickwheel driver that works for the 4g
00:36 < Farthen> do you know the base address of it?
00:36 < cmwslw> this would probably be a step up from the accelerometer i got working
00:36 < cmwslw> farthen: iirc it uses i2c
00:36 < Farthen> ok
00:37 < Farthen> cmwslw: hmm, try out \firmware\target\arm\ipod\button-clickwheel.c
00:38 < Farthen> sorry for the backslashes ;)
00:38 < Farthen> it *should* be the right file
00:38 < slck> cmwslw: do you have some working example that uses your accel. driver on the 4g, because the last time i used one of the functions to init.c, it didn't compile
00:38 < cmwslw> ahh i was looking in the 2g-specific folder, thanks
00:39 < cmwslw> slck: it works for me at least. give me the error and i'll check into it
00:39 < slck> or maybe i used the wrong code .. ok just a sec to recreate it
00:40 < cmwslw> the 4g branch has a bug in the console code, so it prints one character at a time, but it still works
00:41 < slck> what about the dash at the end of CROSS-variable, i saw you've changed it in some of the revisions in trunk
00:42 < Farthen> it is changed back
00:42 < Farthen> you need to use the dash
00:48 < slck> i'm not getting any emails from the mailing list for some reason, can someone check please
00:48 < slck> the last one i got is about commit of revision 57
00:49 < cmwslw> it worked for me
00:49 < cmwslw> btw for some reason there's a redirect loop when someone clicks an old page
00:49 < cmwslw> an old page link on the wiki
00:49 < Farthen> slck: i did not unsubscribe you this time ;)
00:50 < cmwslw> oh i see that you use "wiki" instead of "index.php" in your urls
00:51 < slck> Farthen: i know, but i'm not getting mails for some reason
00:51 < Farthen> let me check the log
00:51 < slck> ok, thanks
00:52 < slck> i got it ... gmail's spam filter has gone crazy
00:52 < Farthen> ok
00:53 < Farthen> the mails can somethime become really big. maybe it doesn't like that for some reason
00:53 < Farthen> *sometimes
00:58 < slck> i use a weird setup ... my catch-all address is hosted withing google apps, then all mail is forwarded to my gmail.com account
00:59 < slck> but it seems that if google apps' filter marks something as a spam, it doesn't get forwarded at all but stuck into its spam folder ;)

12:23 < benedikt93> TheSeven, are the values that can be in struct scheduler_thread.state those in thread_state ?
12:34 < TheSeven> yes
12:34 < TheSeven> see the declaration
12:35 < benedikt93> I wasn't sure because it's uint32_t state; there and not enum thread_state state;
13:08 -!- MrShlee [~Default@219-90-144-75.ip.adam.com.au] has quit [Quit: Leaving]
14:11 < TheSeven> yes, it needed to be a uint32_t because i'm accessing it from asm
14:11 < TheSeven> (to avoid trouble with short enums)

16:09 < cmwslw> and I thought threading was dependent on getting the timer working on the 4g
16:09 < cmwslw> do you have any clues as to how to get this to work?
16:09 < cmwslw> i suppose it would involve looking through the bootrom dump
16:14 < TheSeven> the bootrom probably isn't setting up timers
16:16 < TheSeven> cmwslw: http://theiphonewiki.com/wiki/index.php?title=S5L8720_Timers_%28Hardware%29
16:16 < cmwslw> ugh and we don't have a utility flash dump yet
16:16 < cmwslw> oh forgot about that
16:17 < TheSeven> looks like the iphone guys have already done most of the hard work
16:18 < cmwslw> ok well i'll have to look at the 2g threading code for a bit because I still barely understand threading

18:54 < TheSeven> cmwslw: timer.c and interrupt.c are probably the only files that need changing
18:55 < slck> could someone point me to the commands i need to run embios on nano4g via ibugger
18:57 < TheSeven> ibugger upload 08000000 build/ipodnano4g/embios.bin && ibugger execute 08000000 0a000000
18:57 < slck> thanks, and what's the ucl file for? do i need it some way?

19:32 < TheSeven> slck: not yet. it's a compressed version of it
19:33 < TheSeven> once we're flashing it, we might want to compress it
19:46 < slck> this format is used by iloader, right?
19:46 < TheSeven> for example, yes
19:47 < TheSeven> and by embios loader for the 2g
19:48 < slck> ok
19:57 < cmwslw> i've added some functions that control the backlight in backlight.c and .h
19:58 < cmwslw> and I added backlight.c to SOURCES, and when I compile everything backlight.o is created and linked in later
19:58 < cmwslw> but for some reason my backlight functions are not in the object file so I always get "undefined reference" - any suggestions?
20:01 < cmwslw> wow I'm stupid - I had one empty set of backlight files and the real ones were somewhere else

22:38 < cmwslw> TheSeven: i saw you imported the rockbox libc. My backlight code complains:
22:38 < cmwslw> backlight.c:(.text.backlight_set+0xc): undefined reference to `__aeabi_dmul'
22:38 < cmwslw> backlight.c:(.text.backlight_set+0x10): undefined reference to `__aeabi_d2uiz'
22:38 < TheSeven> urgh. now what are those?
22:39 < cmwslw> because it needs some libc functionality (as far as I know from my googling
22:39 < TheSeven> i'm pretty sure not even rockbox has those
22:39 < TheSeven> see arm/arm-support.S (which i've also cherrypicked from there)
22:42 < TheSeven>     int file = file_open("/.rockbox/config.cfg", O_RDONLY);
22:42 < TheSeven>     char buf[16];
22:42 < TheSeven>     int bytes = read(file, buf, 16);
22:42 < TheSeven>     close(file);
22:42 < TheSeven>     cprintf(3, "Read %d bytes:\n", bytes);
22:42 < TheSeven>     cwrite(3, buf, 16);
22:42 < cmwslw> well apparently it needs those to convert from a double to an integer
22:42 < TheSeven>     int file = file_open("/.rockbox/config.cfg", O_RDONLY);
22:42 < TheSeven>     char buf[16];
22:42 < TheSeven>     int bytes = read(file, buf, 16);
22:42 < TheSeven>     close(file);

22:42 < TheSeven> yay! \o/
22:43 < TheSeven> oh, you're using floating point?
22:43 < TheSeven> that would explain a lot.
22:43 < cmwslw> TheSeven: yea, i didn't want to but i think we need to to maintain a compatible api between the 2g and the 4g
22:43 < TheSeven> we would need to link a whole softfp lib, those cpus don't have a hardware fpu
22:44 < TheSeven> you're talking about a brightness value?
22:44 < TheSeven> just use 0-255 for that, and multiply it with a target-dependent factor
22:44 < cmwslw> yea 32 is fully bright on the 2g but on the 4g its 255
22:44 < cmwslw> oh i hadn't thought of that
22:44 < TheSeven> and 32 isn't full brightness on 2g
22:45 < TheSeven> it's something weird like 46
22:45 < cmwslw> well that means i'd have to use 0-46 then multiply for the 4g wouldn't I?
22:45 < cmwslw> since I can't multiply by a float
22:47 < TheSeven> but you can divice
22:47 < TheSeven> divide*
22:47 < TheSeven> we don't even need a divison
22:47 < TheSeven> (46 * value) >> 8

23:42 < cmwslw> set it to 32 by default
23:43 < TheSeven> it just works?
23:44 < cmwslw> oh it fades. I should use my brain more often. I guess it should stay then
