11:32 < TheSeven> mulenmar: what the hell.
11:33 < TheSeven> you said it loads the apple firmware when touching the wheel after a crash?
11:33 < TheSeven> for me, it quits iloader :)
11:34 < TheSeven> but yeah, apparently the FTL check is messing something up
11:41 < TheSeven> but I can't reproduce any backlight problem at all

12:05 < TheSeven> can you still reproduce the backlight and assertions problems?

12:25 < TheSeven> can you please check if that assertion still fails for you?

13:07 < benedikt93> TheSeven: do you know the processor clock of the s5l8702 in nano 3g?
13:07 < TheSeven> not for sure, but we assume something around 200MHz
13:11 < benedikt93> would 176MHz be possible?
13:17 < TheSeven> might be, but would have expected 192, 200, 240 or 250
13:17 < TheSeven> where have you spotted that?
13:17 < benedikt93> I'm not sure, but in that case timer f has an exact 1us tick
13:18 < TheSeven> what is it derived from?
13:18 < TheSeven> pclk?
13:18 < benedikt93> pclk/16
13:18 < benedikt93> prescaled by 11
13:19 < TheSeven> i doubt pclk would be >100MHz
13:20 < benedikt93> is pclk the clk directly from the crystal?
13:21 < TheSeven> nope
13:21 < TheSeven> it's usually the cpu clock divided by 2 or 4
13:21 < TheSeven> or rather the AHB clock divided by 1 or 2
13:21 < TheSeven> the cpu clock happens to be twice the AHB clock on the 2g, but in theory it can be anything
13:22 < TheSeven> you could try just measuring pclk
13:23 < TheSeven> do you already know at which rate the platform timer of that thing is ticking?
13:23 < TheSeven> on the nano2g it was 5 usecs, on the nano 4g it was 100 nanoseconds IIRC
13:23 < benedikt93> *enter n00b mode* what's the platform timer?
13:25 < TheSeven> haha, interesting
13:25 < TheSeven> it's at 0x3C700080 on both the 2g and 4g
13:26 < benedikt93> oh
13:26 < TheSeven> but it didn't need to be configured in any way on the 2g, it was just a 64bit readonly timer ticking at an insanely high rate
13:27 < TheSeven> so apparently more timers are following that one?
13:27 < benedikt93> I could of course try if that timer is ticking
13:27 < benedikt93> seems so, see the PM
13:27 < TheSeven> you'll need to read it like this to get the lower 32 bits:
13:27 < TheSeven>         ldr     r0, #0x3c700000
13:27 < TheSeven>         ldr     r1, [r0,#0x80]
13:27 < TheSeven>         ldr     r0, [r0,#0x84]
13:28 < TheSeven> the r1 result is the high 32 bits, which are usually thrown away
13:28 < benedikt93> it accesses the timer at 3C700100
13:28 < TheSeven> but reading those is required to update the lower ones
13:28 < TheSeven> (to avoid the lower 32bits wrapping in the middle of a read)
13:29 * benedikt93 remembers sthg similiar from AVRs...
13:57 < benedikt93> hmm
13:58 < benedikt93> if my code is correct, there's nothing ticking at 0x3c700080
13:58 < benedikt93> let's read out that whole are of memory
14:10 < benedikt93> so, either I'm to dumb to make that code work or no timer is ticking in the range from 0x3c700000 to 0x3c700200
14:15 < TheSeven> the latter might well be true
14:16 < TheSeven> if you're booting through DFU, nobody will have set them up yet
14:16 < TheSeven> the bootrom will only do the bare minimum of things needed to make USB and the flash work
14:17 < TheSeven> (and the crypto stuff of course)

19:49 < user890104> i've noticed something about embios.py - the runfirmware command says, that it uploads the firmware file in the beginning of the user memory, but actually asks for an address when called
19:50 < user890104> would it be better to hard-code the 0x08000000 address as the first param, or to allow the user to specify an address and fix the help message?
19:53 < TheSeven> the latter
19:54 < TheSeven> different kinds of firmware want to be executed at different addresses
19:56 < user890104> i've been running apple's OF 1.0.4 on a 1.0.3 ipod nano 4g for weeks with this method
19:56 < user890104> and today the menu button just stopped working
19:56 < user890104> a restart fixed it .. strange
19:57 * TheSeven blames apple
20:00 < user890104> i thought that the clickwheel was broken at first, because even the reset combo didn't work so i'm not sure if it's a software or a hardware issue
20:02 < TheSeven> if the reset doesn't work, it's hardware

20:22 < Farthen> user890104: i will fix it when i will continue to work on embios.py... don't have much time at the moment. of course someone else could do it also if he wants ;)
20:24 < user890104> if i had an account, i would fix it myself after the someone of the others agree
20:25 < Farthen> why do you run the OF 1.0.4? some important improvements? i thought it was mainly made to fix the notes bug
20:26 < user890104> i think it fixes another bug - remembering that i've selected 24-hour format for the time display
20:26 < user890104> 1.0.3 always resets to am/pm display
20:29 < Farthen> 1.0.4 fixes this annoying bug?
20:29 < Farthen> this one has been annoying me all the time!
20:29 < user890104> i think so, but i'm not 100% sure
20:29 < Farthen> but well, i don't want the notes exploit to stop working so i'll just stay with 1.0.3
20:30 < user890104> so my approach is having the ipod flashed with 1.0.3, while running 1.0.4 in the ram memory
20:31 < user890104> but i have to bring the cable and the laptop with me, in case the power goes off and the ipod gets reset to the ibugger's loader screen
20:32 < Farthen> yeah and i don't want to do that
20:32 < Farthen> so i'll just stay with 1.0.3
20:36 < user890104> does anyone know what "*PANIC* Unhandled IRQ 8!" mean while booting emBIOS?
20:37 < TheSeven> which kind of ipod? :D
20:37 < TheSeven> 4g?
20:37 < user890104> yep
20:38 < TheSeven> seems to be a spurious timer interrupt

20:52 < user890104> is there a libembios command, which can be used to write some text to ipod's white screen console?
20:52 < user890104> or it has to be a separate application
20:53 < Farthen> it is theoretically possible with embios.py writedevconsole to console 2 but there is a bug in the embios code for the nano 4g that makes it raise a mutex panic when you do it
20:54 < user890104> i just hit that bug, so i'm in the right direction
20:55 < user890104> i should get a nano 2g to do the testing on it also
