**** BEGIN LOGGING AT Thu Apr 23 02:59:57 2009
Apr 23 09:15:51 <Sleep_Walker> morning
Apr 23 09:44:23 <marex> Sleep_Walker, I sent some patches to LAKML, the GPIO VBUS one might be interesting for you
Apr 23 09:47:31 <Sleep_Walker> marex: thanks for info, I'll check that
Apr 23 09:47:41 <marex> dammit
Apr 23 09:47:52 <marex> there's either bug in linux kernel or in cocoboot, but something is broken again
Apr 23 09:48:13 <marex> palmte2 indicates 16megs of ram in cocoboot, but 8 in linux
Apr 23 09:48:25 <marex> maybe the atag is done for ... hmmm
Apr 23 09:49:38 <marex> hrm jeez ... now it works
Apr 23 09:49:44 <marex> probably old version of cocoboot
Apr 23 09:52:29 <marex> damn, it works randomly
Apr 23 21:46:46 <mpannen> hmm v0.6.1 cocoboot that I just compiled from git works on my treo 755p but anything newer than that tag crashes before I even see the cocoboot config screen..I am not a programmer anyone have any ideas what the next commit after that could have done?
Apr 23 21:48:37 <mpannen> 3/26/2009 and newer crashes..I didnt check the two commits before that yet
Apr 23 21:50:57 <marex> mpannen, dunno, there were no changes that could crash your device
Apr 23 21:51:04 <marex> why dont you use some precompiled binary ?
Apr 23 21:51:14 <marex> what toolchain do you use ?
Apr 23 21:52:20 <mpannen> ive tried as many pre-compiiled ones as i could find, but whenever i try to boot my treo 755p resets, so I decided to try compiling my own from git
Apr 23 21:52:29 <mpannen> boot linux
Apr 23 21:54:00 <mpannen> the one i tried from the newest commit doesnt even load cocoboot, it resets the phone immedidately, however the 0.6.1 tag that i compiled myself does load (but still crashed upon trying to load the kernel)
Apr 23 21:54:15 <mpannen> does that make any sense?
Apr 23 21:54:27 <marex> hang on
Apr 23 21:54:28 <mpannen> my explanation, does that make sense?
Apr 23 21:54:49 <marex> http://marex.hackndev.com/cocoboot-xscale-dump.prc
Apr 23 21:55:01 <marex> try this one, tap Menu -> LCD registers
Apr 23 21:55:08 <mpannen> ok
Apr 23 21:55:10 <mpannen> one sec
Apr 23 21:55:16 <marex> I wonder if it resets the device
Apr 23 21:56:38 <mpannen> yes it does immediately upon trying to load the app
Apr 23 21:56:56 <marex> while loading you say ... hmm
Apr 23 21:56:59 <mpannen> yes
Apr 23 21:57:12 <mpannen> not booting linux, but the load of cocoboot
Apr 23 21:57:20 <marex> yes, I got your point
Apr 23 21:57:23 <marex> damn
Apr 23 21:57:25 <mpannen> ok
Apr 23 21:59:50 <marex> the only change I can think of is the ram detection code
Apr 23 22:00:11 <marex> how much ram does T755p have ?
Apr 23 22:00:27 <mpannen> hmm
Apr 23 22:01:24 <mpannen> i thought it was 32mb
Apr 23 22:01:31 <mpannen> not sure how to verify that
Apr 23 22:01:59 <marex> see m68k/mem.c ... try sticking return 0x2000000; at the top of that function
Apr 23 22:02:14 <marex> errr ... at the top of get_ram_size();
Apr 23 22:02:20 <mpannen> ive reverted back to 3/26 and that crashed too
Apr 23 22:02:22 <mpannen> ok
Apr 23 22:02:46 <mpannen> which version of git?
Apr 23 22:02:51 <marex> latest
Apr 23 22:02:54 <mpannen> ok
Apr 23 22:05:44 <mpannen> right after that first bracket?
Apr 23 22:06:20 <marex> right past line 70
Apr 23 22:06:37 <marex>  68 UInt32 get_ram_size()
Apr 23 22:06:37 <marex>  69 {
Apr 23 22:06:37 <marex>  70         UInt32 mem; return 0x2000000;
Apr 23 22:06:37 <marex> .... }
Apr 23 22:09:22 <mpannen> ok cocoboot loaded!
Apr 23 22:09:28 <mpannen> should i try the kernel?
Apr 23 22:09:55 <marex> what kernel ?
Apr 23 22:10:00 <mpannen> linux?
Apr 23 22:10:12 <marex> well yes, but what kernel exactly
Apr 23 22:10:17 <marex> treo680 one ?
Apr 23 22:10:45 <mpannen> i compiled one from arm-devel plus patches
Apr 23 22:10:56 <mpannen> or ii could download the 680 one that is done
Apr 23 22:11:29 <marex> well if you have one, go ahead, good luck
Apr 23 22:11:48 <marex> dont forget to change the machine ID either in the kernel or in cocoboot
Apr 23 22:12:08 <mpannen> heh lol i forgot
Apr 23 22:12:42 <flyback> hey marex
Apr 23 22:12:45 <flyback> how is the jtag building going
Apr 23 22:13:01 <marex> havent touched it yet
Apr 23 22:13:31 <flyback> ah ok
Apr 23 22:13:40 <flyback> let me know how it goes
Apr 23 22:13:53 <flyback> that xlinx one looked insteresting, basically a wiggler with extra functions
Apr 23 22:14:16 <marex> mpannen, so ... how's it going ?
Apr 23 22:14:55 <mpannen> my kernel load resulted in a reset with mach id 1230, im gonna try the treo one right now
Apr 23 22:15:20 <mpannen> http://sleepwalker.hackndev.com/release/T680/linux-2.6-arm/partition/4/
Apr 23 22:15:23 <marex> mpannen, try Disable memory protection from menu
Apr 23 22:15:27 <marex> before booting
Apr 23 22:15:30 <mpannen> is that the one i should try?
Apr 23 22:15:34 <mpannen> ok
Apr 23 22:15:56 <marex> dunno, SleepWalker is offline now but he comes here often
Apr 23 22:16:03 <marex> http://sleepwalker.hackndev.com/release/T680/linux-2.6-arm-hnd/kEdAR/1/zImage.T680.sw1 try this too
Apr 23 22:17:05 <mpannen> ok ill give em a download...i can just use the kernel image to test? or do i have to install the rootfs and modules to check the boot?
Apr 23 22:17:22 <marex> nah, just use the kernel itself
Apr 23 22:17:49 <marex> actually, to bring up a new platform might be a little tricky
Apr 23 22:18:08 <marex> I guess you don't know the GPIO setup yet for T755p, right ?
Apr 23 22:18:52 <ijaera> hi everybody
Apr 23 22:19:06 <mpannen> well i have dumps from gpiotrace and haret/p
Apr 23 22:19:07 <marex> mpannen, btw. once you tap that "Disable memory protection", you'll be able to use any cocoboot without modification till reboot
Apr 23 22:19:09 <marex> ijaera, hello
Apr 23 22:19:28 <marex> mpannen, gpiotrace sucks, but ok ;)
Apr 23 22:19:33 <mpannen> oh
Apr 23 22:19:43 <marex> it does it's job somehow
Apr 23 22:20:05 <mpannen> just from some addresses ive seen posted using haret
Apr 23 22:20:48 <marex> ijaera, what do you need ?
Apr 23 22:21:44 <marex> mpannen, look, what you need to do now: take t680 sources, strip away all you dont need from arch/arm/mach-pxa/t680.c (or st. like that) - that is backlight, irda, gsm, leave just framebuffer
Apr 23 22:21:50 <marex> also, disable mfp config
Apr 23 22:21:55 <marex> you might be able to boot using that
Apr 23 22:22:32 <mpannen> ok
Apr 23 22:25:21 <ijaera> marex: im sorry
Apr 23 22:25:24 <ijaera> i was AFK
Apr 23 22:25:27 <ijaera> now im back
Apr 23 22:25:45 <ijaera> i just want to get more knowledge bout the defacement world
Apr 23 22:26:12 <marex> about what ?
Apr 23 22:26:39 <ijaera> defacement
Apr 23 22:26:47 <ijaera> have u ever heard to talk about?
Apr 23 22:27:46 <marex> I dont unterstant ur engrisch
Apr 23 22:28:08 <mpannen> heh
Apr 23 22:28:57 <ijaera> sorry
Apr 23 22:29:00 <ijaera> im braziliand
Apr 23 22:29:16 <ijaera> and i havent so much experience with ehglish
Apr 23 22:29:16 <marex> no problem ... so what do you need ? anything related to handheld hacking ?
Apr 23 22:29:22 <marex> or linux ?
Apr 23 22:29:23 <ijaera> no
Apr 23 22:29:28 <ijaera> linux
Apr 23 22:29:29 <marex> I dont have that word in my dictionary
Apr 23 22:29:36 <ijaera> defacement?
Apr 23 22:29:39 <marex> yes
Apr 23 22:29:41 <ijaera> wow
Apr 23 22:29:41 <ijaera> here
Apr 23 22:29:50 <ijaera> its a word very famous
Apr 23 22:30:04 <marex> ijaera, so ... what about linux do you need ?
Apr 23 22:30:05 <ijaera> let me pick up a wikipedia link
Apr 23 22:30:05 <ijaera> for u
Apr 23 22:30:09 <marex> mpannen, how's it going ?
Apr 23 22:30:16 <marex> ijaera, Im fine without it
Apr 23 22:30:29 <ijaera> ok
Apr 23 22:30:50 <ijaera> i wanted to learn a little bit more about defacement
Apr 23 22:31:00 <ijaera> but you dont know about that
Apr 23 22:31:51 <adfaf> hi
Apr 23 22:31:54 <mpannen> the inux-2.6-arm/partition/4/ kernel reset the phone
Apr 23 22:32:03 <adfaf> sql inj
Apr 23 22:32:05 <adfaf> ?
Apr 23 22:32:10 <marex> mpannen, start stripping down the kernel
Apr 23 22:32:12 <mpannen> im working on downloading the hnd one right now
Apr 23 22:32:14 <mpannen> ok
Apr 23 22:32:20 <marex> adfaf, read the topic, go to hell, good bye
Apr 23 22:32:44 <adfaf> what is handhelds stf u
Apr 23 22:32:52 <mpannen> lol
Apr 23 22:33:47 <mpannen> is there a specific kernel .config i should use to start with?
Apr 23 22:33:50 <marex> now he starts spamming my PM ... jeez
Apr 23 22:33:57 <mpannen> besides the code modification
Apr 23 22:34:01 <marex> mpannen, probably the treo680 one
Apr 23 22:34:21 <marex> but also strip it to bare minimum (just the machine support and framebuffer, nothing else)
Apr 23 22:36:01 <marex> mpannen, it's for best to compile the kernel yourself with minimum configuration ... I have serious suspicion that the T755p hardware is different from T680 one which results in problems while loading the kernel
Apr 23 22:36:16 <mpannen> ok
Apr 23 22:36:22 <marex> (the mainline kernel configures the CPU properly (that's the MFP))
Apr 23 22:37:24 <mpannen> i should just comment out the appropriate GPIO1_GPIO | WAKEUP_ON_EDGE_BOTH
Apr 23 22:37:32 <mpannen> stuff like that?
Apr 23 22:37:56 <mpannen> i see they are commented here and there
Apr 23 22:39:29 <marex> see the bottom of the file
Apr 23 22:40:14 <marex> there is static void __init palmsomething_init(void)
Apr 23 22:40:25 <marex> comment out pxa2xx_mfp_config
Apr 23 22:40:25 <mpannen> ok
Apr 23 22:40:31 <marex> well
Apr 23 22:40:45 <marex> comment out everything but set_pxa_fb_info();
Apr 23 22:40:51 <marex> in that function
Apr 23 22:40:55 <marex> that might do the trick
Apr 23 22:44:16 <mpannen> platform_add_devices(devices, ARRAY_SIZE(devices));
Apr 23 22:44:18 <mpannen> 	setup_unknown_in_gpios();
Apr 23 22:44:22 <mpannen> how about those?
Apr 23 22:44:25 <mpannen> gone?
Apr 23 22:44:32 <marex> remove it all
Apr 23 22:44:43 <marex> leave just set_pxa_fb_info()
Apr 23 22:45:23 <mpannen> ok
Apr 23 22:52:44 <mpannen> compiling right now
Apr 23 23:02:23 <mpannen> hmm machid 1230, diabled mem protection, and the new zImage with that stuff commented out and it resets, i am guessing that wasnt expected
Apr 23 23:04:18 <mpannen> does the program have any output that verifies that mem protection was disabled or is it silent?
Apr 23 23:06:49 <mpannen> should i turn off preemtible kernel?
Apr 23 23:10:25 <mpannen> thanks for your help im gonna keep stripping kernel options and try again
Apr 23 23:12:47 <flyback> marex
Apr 23 23:12:59 <flyback> what is status of disk on chip g3 I think is what they used in t5
Apr 23 23:14:05 <mpannen> if i disable memory protection and thenn select 'dump mmu' should that casue the device to reset?
Apr 23 23:16:58 <flyback> if this is a palm os device
Apr 23 23:17:05 <flyback> why do you need to disable memory protection or dump mmu
Apr 23 23:17:06 <mpannen> oh apparently it has 128mb of ram, not 32
Apr 23 23:17:10 <flyback> isn't that palm os native? :P
Apr 23 23:17:29 <mpannen> haha
Apr 23 23:17:40 <mpannen> what,,,the crashing part?
Apr 23 23:17:42 <mpannen> haha
Apr 23 23:18:33 <flyback> palm os and mmu don't go together
Apr 23 23:18:34 <flyback> never did
Apr 23 23:18:49 <flyback> I am very disappinted in my t5 but I am goign to spend around $100 to get it fixed up and run it till it dies
Apr 23 23:18:57 <flyback> cause I got about $500 in it not going to just toss it
Apr 23 23:19:03 <flyback> espically once I get linux on it 24/7
Apr 23 23:19:11 <flyback> the biggest holdback is all my plucker files
Apr 23 23:20:40 <marex> mpannen, sorry, I was away for a while
Apr 23 23:21:19 <marex> palmos uses MMU extensively
Apr 23 23:21:42 <flyback> uh
Apr 23 23:21:44 <flyback> since when?!?!?
Apr 23 23:21:47 <marex> mpannen, no, disable memory protection doesnt give any output, it just doesn't reset when you tap "LCD registers" or such stuff
Apr 23 23:21:54 <marex> flyback, ever since 5.0
Apr 23 23:22:06 <flyback> uh no
Apr 23 23:22:06 <mpannen> marex, the treo755p has 128mb not 32mb
Apr 23 23:22:09 <flyback> it still can't multitask
Apr 23 23:22:14 <flyback> apps can shitcan the os all the time
Apr 23 23:22:16 <marex> mpannen, I think those 128 megs is just non-volatile memory
Apr 23 23:22:24 <mpannen> and even with oh
Apr 23 23:22:51 <marex> flyback, treos use arm memory protection
Apr 23 23:22:57 <mpannen> it resets when i tap on lcd registers even with protection disabled
Apr 23 23:23:12 <marex> that's bad
Apr 23 23:23:16 <marex> very bad actually
Apr 23 23:23:24 <flyback> marex could have fooled me
Apr 23 23:23:27 <flyback> not from what I seen
Apr 23 23:23:34 <marex> there's only one more thing I can think of - palmos running not in system mode
Apr 23 23:23:42 <mpannen> yeah thats what i thought
Apr 23 23:24:01 <mpannen> can that change based on the rom file in the phone?
Apr 23 23:24:06 <marex> flyback, ram is mapped at VA 0x0, PA is 0xa<<28, fine ?
Apr 23 23:24:19 <marex> mpannen, I doubt so
Apr 23 23:24:21 <flyback> PA ?
Apr 23 23:24:25 <marex> physical address
Apr 23 23:25:19 <flyback> what's the point
Apr 23 23:25:29 <flyback> it's obvious the os isn't doing a good job
Apr 23 23:25:59 <flyback> I believe you I am just surprised
Apr 23 23:26:08 <flyback> considering what a fucking piece of shit palm os was
Apr 23 23:26:11 <flyback> glad to see it die
Apr 23 23:26:49 <mpannen> ok so now i see that it has 60mb of ram avail for apps out of a total of 64mb
Apr 23 23:27:14 <mpannen> would that affect the memory protection? sorry i havent much of a clue on these things
Apr 23 23:28:27 <marex> flyback, calm down
Apr 23 23:28:43 <flyback> I am not angry with you :)
Apr 23 23:28:47 <marex> mpannen, that has nothing to do with it
Apr 23 23:28:51 <mpannen> ok
Apr 23 23:28:53 <flyback> my t5 was just a dissapointment I put a lot of time and money into
Apr 23 23:28:59 <marex> flyback, but you spew naughty words again
Apr 23 23:29:09 <flyback> oh those bother you?
Apr 23 23:29:10 <flyback> ok
Apr 23 23:29:31 <marex> mpannen, sorry, but I'll have to take my leave, it's 1.30am here and I'm teaching tomorow (today) at 7
Apr 23 23:29:35 <marex> (am)
Apr 23 23:30:07 <mpannen> ouch
Apr 23 23:30:09 <mpannen> ok
Apr 23 23:30:10 <marex> mpannen, I'm sure you can try tracing where cocoboot hangs
Apr 23 23:30:24 <marex> if you know which GPIO for example controls some LED, that can be useful
Apr 23 23:30:24 <mpannen> yeah i was gonna mess with that
Apr 23 23:30:39 <mpannen> thanks for your time
Apr 23 23:30:51 <marex> or you can just stop the LCD clock ... no whine => you hit the checkpoint ;)
Apr 23 23:31:04 <marex> no problem, I'll be here tomorow probably
Apr 23 23:31:22 <marex> I hope you won't give up too easily ;)
Apr 23 23:31:26 <mpannen> heheh
Apr 23 23:31:48 <mpannen> i have the house to myself this weekend no one to piss off if i am on front of the computer
Apr 23 23:32:01 <marex> hehe :)
Apr 23 23:32:05 <mpannen> :)
Apr 23 23:32:41 <marex> gnight
Apr 23 23:34:24 * flyback has a bad feeling something is about to happen to this area
