07:19 < XQYZ> TheSeven: Regarding the corruption on lcd type 3: I was just playing around and if I start the game "rockblox" (tetris) the display seems normal.
07:19 < XQYZ> The colors and all don't seem off at all here, except for a small line which is always (even when it is corrupted) present at the top of the screen (~1px). The line extends maybe 4/5 of the width of the display and is 3/4 cyan and then dark blue
07:19 < XQYZ> Here's another shot of iLoader with the weird colors: http://img193.imageshack.us/img193/5714/photo0096je.jpg
07:19 < XQYZ> Here's rockblox in all it's glory: http://img211.imageshack.us/img211/7255/photo0103u.jpg
07:19 < XQYZ> Hope this helps you nail down what could be the problem
07:21 < XQYZ> actually thinking about it it almost looks like that line is a leftover from the iloader screen

14:55 < sinless> hello,thseven?
14:56 < TheSeven> yea?
14:58 < sinless> hey,i have someting about screen to tell you..
14:59 < sinless> The problem LCD has a small tube looks like a rheostat on the wire.It is similiar to NANO2G's type 2 lcd,type1 lcd doesn't has a rheostat 
15:00 < Farthen> what are you talking about?
15:01 < Farthen> and what's a rheostat?
15:01 < TheSeven> he probably means some small smd potentiometer
15:01 < TheSeven> the type 3 lcd of my classic 3g shows the same kind of corruption in rockbox, but is perfectly fine in embios
15:02 < TheSeven> er, type 2
15:02 < sinless> I think the color is wrong..
15:02 < Farthen> but why does that have any interest for us if the lcd has a potentiometer?
15:02 < TheSeven> yes, the colors are wrong in iloader. embios just doesn't seem to use any of the colors that get translated wrongly
15:03 < TheSeven> so apparently we're still having a bug in the type 2/3 init sequence, which is currently this: http://pastie.org/1440169
15:03 < sinless> ..there are at least 4 types of screens..
15:04 < TheSeven> from a software point of view, there are four distinguishable types, but two of them are dealt with in the exact same way
15:05 < sinless> one print sn at the middle of the back using big front,seems samsung's,one print sn at the top,one at the buttom,one at the middle using small front
15:06 < TheSeven> that's the sequence apple uses: http://pastie.org/1440176
15:06 < sinless> and do you need other hardware's infmation,I can dump every chip instead
15:08 < sinless> that website seems unreachable in China..likes youtube..
15:08 < TheSeven> blame your government... or use ultrasurf...
15:08 < TheSeven> (both of which are probably highly illegal in china)
15:09 < sinless> Yes..I uses VPN instead..
15:11 < sinless> oh,and i have a question to ask you,maybe you can help..I have a nano3,water damaged,with no display
15:12 < sinless> I have plenty of broken ipods,nano3,nano4,classic is the most..Email me if you need chip details:)
15:12 < TheSeven> are you working at a repair shop? :=
15:13 < sinless> no,in fact i'm a senior student,i have a friend who reapirs mobile phone

15:18 < sinless> I just play with iDevices...buy broken ipod at around $10,and he will fix them for me..I started to watch L4N team's progress since 2007..And there is a very similiar problem,rockbox's onda vx747 port and vx777 port shares the same build,the two devices have the same motherboard and screen,but on vx777,the display problem is the same to classic.AUO's screen is surely bad..

17:01 < mmarker> Anyone awake? Is it wise for one to compile the code in SVN and use it? Have a linking error that's flat out annoying. arm-elf-eabi-ld: build/ipodclassic/umsboot.elf section `.ibss' will not fit in region `SRAM'
17:01 < mmarker> arm-elf-eabi-ld: region `SRAM' overflowed by 432 bytes
17:02 < [Saint]> mmarker: Well, the build server doesn't seem to have a problem compiling it.
17:03 < [Saint]> [13:57] <@fmibot> New commit by theseven (r418): UMSboot: Fix iPod Nano 2G LCD driver
17:03 < [Saint]> [13:57] <@fmibot> r417 build result: All green!
17:03 < mmarker> Hmm, it may be a gcc issue then. Know what version the buildserver uses?
17:03 < [Saint]> No idea.
17:03 < mmarker> Ok, I see what it's doing
17:03 < mmarker> seems like my gcc version started inlining functions
17:03 < mmarker> still 80 bytes over.
17:04 < [Saint]> what is it you're compiling?
17:05 -!- Keripo [~Keripo@CPE0022b0d4bdb7-CM001a6680d4fe.cpe.net.cable.rogers.com] has joined #freemyipod
17:05 < mmarker> umsboot and ipodclassic-installer
17:05 < mmarker> It looks like it's a gcc being too smart for its own good
17:16 < TheSeven> i've seen similar problems before
17:16 < TheSeven> the build server uses the rockbox eabi toolchain, but i'm not sure if that one even works (the buildserver doesn't compile umsboot)
17:17 < mmarker> TheSeven: using an eabi toolchain
17:17 < TheSeven> i am using the yagarto toolchain, and that one works, but space is pretty tight in umsboot
17:17 < mmarker> What it looks like is there's some minor differences in optimization flags used by GCC between versions
17:17 < mmarker> Os on 4.4.4 does inlining
17:17 < mmarker> which is daft

17:19 < mmarker> yagarto is win32?
17:19  * mmarker grabs his crosstool scripts and slaps together a 4.5.2
17:22 < mmarker> Or be lazy and use debians
17:24 < XQYZ> or gentoo: crossdev builds complete toolchains for any desired platform
17:24 < TheSeven> apple's LCD init decoded: http://pastie.org/1440497
17:24 < mmarker> XQYZ: all my ARMs run some variant of debian
17:25 < mmarker> Well, the pogo runs Arch...but that's an odd box
17:25 < mmarker> Yes, I have more ARM based computers on my home network than X86
17:45 < TheSeven> my LCD init decoded: http://pastie.org/1440549
17:48 < TheSeven> so the only difference is some tiny amount of delay

18:10 < mmarker> Hmm. So what is the way to install the iPod classic stuff in Linux?
18:11 < XQYZ> flash http://files.freemyipod.org/misc/bootstrap-ipodclassic.dfu with http://svn.freemyipod.org/tools/ipoddfu/
18:13 < XQYZ> and then put http://files.freemyipod.org/misc/installer-classic.ubi on the usb mass storage device
18:13 < XQYZ> you need pyusb >= 1.0 thought
18:13 < mmarker> Got that already
18:13 < mmarker> Just needed the file to upload when in DFU mode
18:18 < mmarker> woot! works
18:21 < mmarker> Taking it's time installing files...but seems to be OK
18:25 < mmarker> Hmm. Solid white screen...still in DFU mode. Weird
18:26 < XQYZ> had that too
18:26 < XQYZ> just wait for a while
18:26 < XQYZ> then reset it and it'll be fine
18:26 < mmarker> Ahh, just recet it and it looks good
18:27 < [Saint]> that seems to have happened on atleast 3 Classics I know of now.
18:27  * [Saint] wonders if TheSeven knows what causes it.
18:27 < XQYZ> he said he can't reproduce it on his when I mentioned it
18:28 < [Saint]> yes, but there's yourself, mmarker, and another this has happened to.
18:28 < [Saint]> So it is obviously reproducable
18:28 < XQYZ> <TheSeven> interesting, someone has reported something similar before, but it doesn't happen on mine
18:28 < XQYZ> <TheSeven> it seems to get stuck during shutdown
18:28 < XQYZ> <TheSeven> maybe an issue with some specific LCD or hard drive
18:29 < TheSeven> hm, that seems to happen on the 3g, but not the 1g classic, as far as i can tell
18:29 < TheSeven> or maybe it's related to LCD type 2/3
18:29 < XQYZ> no 1G here and it happened
18:29 < XQYZ> lcd type 3, so that might be something
18:29 < mmarker> 2G here
18:29 < TheSeven> then it basically must be the LCD
18:29 < TheSeven> do those ipods all suffer from LCD corruption?
18:29 < XQYZ> mine does
18:29 < mmarker> My screen looks good
18:30 < [Saint]> well, that's my suggestion out the window.
18:31 < [Saint]> I was thinking perhaps the install *is* completing as normal, but the screen just fails to represent this...but there seems to be different generations, with/without LCD problems, with the same issue
18:31  * [Saint] shrugs.

18:33 < mmarker> If it's "corrupt", the screenshots in the wiki show a offset to the right a bit, correct?
18:33 < TheSeven> wrong colors and sometimes offsets
18:34 < XQYZ> its basically shifted to the left and the left part comes out at the right side
18:34 < mmarker> hmm. Lemme check the colors again
18:34 < TheSeven> however the offsets only seem to occur in rockbox, not in embios/iloader
18:34 < mmarker> but it's supposed to be greyish, correct?
18:34 < [Saint]> I believe "corrupt" also == slight discolouration.
18:34 < [Saint]> ah, yes...what TheSeven said
18:34 < TheSeven> if the ipod on the right side of the iloader menu is green, you have endianness problems

20:06 < benedikt93> does anybody here know something about an executable format identified by 0xEF1FAB9 ?
20:20 < TheSeven> benedikt93: can you provide more context?
20:27 < benedikt93> the EFI code that somehow parses the executable at some point checks for that magic number. google reveals only that this one has been found in AppleTV EFI implementations.
20:28 < benedikt93> It's not really important and the ipod doesn't seem to use it
20:28 < benedikt93> though it might help to get some clue about that damn code
20:29 < benedikt93> s/important and/important as
20:37 < benedikt93> hmm...it seems to effectivly just fetch some offset into the file at that point. so maybe really the fat executable google tells of
20:51 < fmibot> New commit by theseven (r419): Fix iPod Classic LCD problems
20:51 < XQYZ> is that iLoader problems only?
20:51 < fmibot> r419 build result: All green!
20:52 < TheSeven> everything from the freemyipod side
20:52 < TheSeven> so basically everything besides rockbox
20:52 < TheSeven> a fix for that will follow in a few minutes
20:52 < XQYZ> should i test it then?
20:54 < TheSeven> damn
20:54 < TheSeven> it fixes the wrong colors, but not the horizontal shift
20:55 < XQYZ> from the looks of it it seems like rockbox is addressing the vidram with an +offset
21:01 < TheSeven> yeah, and i think i just found the cause for that (a leftover from the nano2g code)
21:07 < TheSeven> i'll release fixed binaries in a few minutes, when they finish compiling
21:42 < TheSeven> XQYZ: files have been pushed :)
21:58 < XQYZ> works great. the rockbox that was flashed is foobar and doesn't work properly, but I updated it with the recent build and that works great

22:14 < XQYZ> flac plays nicely also
22:14 < XQYZ> only thing as I said: installer flashed a corrupted rockbox (it worked, but display was totally unreadable)
22:23 < TheSeven> actually the installer *didn't* update rockbox, and that's why it didn't work any more
22:23 < XQYZ> oh ok that's it then

22:46 < TheSeven> it's the "diagflsh" image
22:47 < asmmonkey> in which address?
22:47 < TheSeven> that depends on the firmware version and ipod model
22:47 < TheSeven> somewhere in the second half of the flash
