| 00:50.16 | cr2 | hi lkcl |
| 00:52.09 | lkcl | heya cr2 |
| 00:52.25 | lkcl | just had a mad day... |
| 00:52.48 | cr2 | what were you doing ? |
| 00:55.08 | lkcl | interview, arranging some work, visiting a friend on the way back... and then, at 10pm tonight on my way back i found someone illegally walking down the motorway... |
| 00:56.06 | cr2 | hehe. have you rolled over him ? |
| 00:56.32 | lkcl | her. |
| 00:57.05 | lkcl | no, that was the point: she was wearing dark clothing, i _had_ to stop.... and it turns out she has _no_ money, _no_ food ... |
| 00:57.30 | lkcl | but is still determined to get home (which is about... two hours drive away) |
| 00:58.17 | lkcl | i dunno .... |
| 00:58.21 | lkcl | *sigh*. |
| 01:01.18 | cr2 | crazy. in january. |
| 01:02.03 | cr2 | two hours drive away ??? |
| 01:03.01 | lkcl | yeh. |
| 01:03.35 | lkcl | i tried to put her on a train but it was too late - the last train to get to where she wanted to go, tonight, was 8pm. |
| 01:03.42 | lkcl | *sigh* |
| 01:04.06 | cr2 | not surprising. so late. |
| 01:04.34 | lkcl | oh well. just passing through... |
| 01:09.35 | cr2 | i am filling the form to send my universal for the repair. weird. radio reset gpio broke it... |
| 01:12.59 | lkcl | que??? |
| 01:13.08 | lkcl | odd. |
| 01:15.22 | cr2 | error description: windows os hangs during the bootup. |
| 01:20.49 | cr2 | odd is that wince sets gpio123 for IR ;) |
| 01:26.08 | lkcl | that like... exists?? |
| 01:26.18 | cr2 | no. |
| 01:26.31 | lkcl | that's somewhere random in memory, then, effectively.. |
| 01:27.04 | cr2 | these bits are reserved. |
| 01:27.27 | cr2 | it is a cpu register. |
| 01:33.30 | cr2 | but there is no such physical pin. i have downloaded the pin layout. |
| 01:35.03 | cr2 | lkcl, create the oe config for the universal :) at the end we will win! now i am falling asleep. good night. |
| 01:47.12 | lkcl | ack dude :) |

| 09:00.26 | rob_w-cgi | i had a very good test this morning ... sofar the ba works smoothly , apmd is reacting and sound resumes .. still some things to fix but yet very cool |
| 09:01.11 | rob_w-cgi | i does wake up for no obvious reason .. though |
| 13:56.29 | cr2 | universal is on its way to repair. hehe. we will see the reaction ;) |

| 19:14.44 | rob_w | brb , trying to extract my contacts |
| 20:20.24 | Funklord | I'm thinking of buying this: http://www.sparkfun.com/commerce/product_info.php?products_id=609# |
| 20:20.28 | Funklord | sounds better to me than modifying hair dryers |
| 20:22.45 | bhima | Definitely better than modifying hair dryers, but not necessarily what you want to use. Depends on what the solder job is. What sort of parts are you soldering? |
| 20:28.17 | Funklord | well, I'd like to be able to do a bga =P |
| 20:28.40 | Funklord | and my current iron does nothing about the fumes |
| 20:29.19 | bhima | How many pins, on what pitch, is the BGA package you want to do? |
| 20:29.55 | bhima | I think that soldering a BGA package yourself is a bad idea. |

| 20:51.02 | Funklord | bhima: not sure about those things yet =P only for the odd project/prototype or repairs |
| 20:52.11 | Funklord | I had a bga package come off my laptop mobo before, so one of these would have been useful to repair it |
| 20:52.50 | Funklord | and.. I need to do wire shrinking sometimes too |
| 21:17.39 | rob_w | did anyone ever see cp15`s gpe-contact patches ? |
| 21:18.09 | cr2 | did anyone ever seen cp15 ? |
| 21:22.46 | rob_w | hehe |
| 21:23.44 | cr2 | well, i have seen him in Berlin, but then he has disappeared :-( |
| 21:25.20 | rob_w | he is a business man , he needs to find his money every day .. although he is a damn good coder |
| 21:26.12 | cr2 | it is true. |
| 21:28.19 | cr2 | i have no universal now, but feel happy that have found a bug in the IR driver :) |
| 21:29.31 | cr2 | rob, what do you think i should do with ba ? |
| 21:29.40 | rob_w | hold it |
| 21:29.49 | cr2 | what for ? |
| 21:30.00 | rob_w | as still cp15 is true , that we could use that doc chip for testing |
| 21:30.11 | rob_w | cr2 how much do you want for it ? |
| 21:30.43 | cr2 | no idea, i will better throw it away :) |
| 21:31.10 | rob_w | send it ! |
| 21:31.20 | rob_w | to me |
| 21:31.53 | cr2 | hmm. |
| 21:32.15 | cr2 | i will think about it. |
| 21:32.21 | rob_w | and if please also send the broken lcd |
| 21:32.39 | cr2 | lcd is already thrown away. |
| 21:33.05 | rob_w | hehe |
| 21:33.24 | rob_w | i will pay for that , np |
| 21:34.08 | cr2 | have you tried to flash the ba from the sd card ? |
| 21:34.28 | rob_w | i not even touched any flash driver at all on the ba |
| 21:34.44 | cr2 | imho, reflashing linux in place of wince rom is absolutely harmless. |
| 21:35.10 | cr2 | but we need a clever way to create this "update" rom. |
| 21:35.13 | rob_w | well , do we have a DoC G3 driver yet ? |
| 21:35.37 | cr2 | not g3. pxa263 flash. |
| 21:35.57 | cr2 | how is it partitioned ? |
| 21:36.38 | rob_w | eh ? so i thought the ba has DoC G3 only |
| 21:37.05 | cr2 | pxa263 means it has flash. cp15 has written a driver. |
| 21:37.25 | cr2 | i have even copied the bootloader with dd ;) |
| 21:37.53 | cr2 | universal is pxa270 (0 at the end) and only g3. |
| 21:38.16 | rob_w | so ba has pxa flash + g3 ? |
| 21:38.20 | cr2 | magician and alpine are pxa272. also with flash. |
| 21:38.22 | cr2 | yes. |
| 21:38.39 | rob_w | ok so let me get this straight |
| 21:38.55 | cr2 | it is very dangerous to mess with g3 on universal, but not on others. |
| 21:39.00 | rob_w | that pxa flash is access with which module ? |
| 21:39.15 | cr2 | bluenagle_rom |
| 21:40.25 | rob_w | right , ok so that gives me that |
| 21:40.29 | rob_w | hmm bootloader we also have now ... what are we waiting for ?!? |
| 21:40.50 | cr2 | do not touch the bootloader :) you don't have jtag. |
| 21:41.19 | cr2 | we need a way to boot from the htc bootloader. |
| 21:42.01 | rob_w | http://handhelds.org/moin/moin.cgi/HpIpaqHx4700OriginalBootloader maybe ? |
| 21:42.20 | cr2 | i have managed to put the "kernel" into RAM on universal with the htc bootloader, but i am not sure what it has done with mmu and other minor things. |
| 21:42.48 | cr2 | you can disassemble your own. |
| 21:43.19 | cr2 | much more difficult on universal where everything is locked down. |
| 21:44.05 | cr2 | the hx4700 way is not really correct. it can/should be made cleaner. |
| 21:44.50 | cr2 | there is a sdtool.pl perl script on xda-dev |
| 21:45.26 | cr2 | since we are not loading "wince os rom" some things should be different. |
| 21:45.50 | cr2 | hx4700 bootloader "looks" like a wince os rom. |
| 21:46.58 | cr2 | it has the "CECE" signature and the typical jump 0x4096 as the first instruction. i'm not sure it is enough. |
| 21:47.55 | rob_w | very cool .. but ... say ahm |
| 21:48.22 | rob_w | what filesystem will i see when loading blueangel_rom ? |
| 21:48.54 | cr2 | "raw" partitions |
| 21:49.56 | cr2 | but they have a special structure. |
| 21:50.10 | rob_w | sure and on them , there is not some ce stuff ? |
| 21:51.03 | cr2 | they are "mmaped" as SRAM into the address space. bootloader completely, and the wince partially (XIP regions) |
| 21:51.47 | cr2 | wince2005 has a different way, it mounts the filesystem like linux. |
| 21:53.02 | cr2 | this is just a dump of the *.nba files described on xda-dev |
| 21:53.11 | rob_w | that ce flash layout on ba totally confused myself so i now cant even say what is in the ba ?!? |
| 21:53.12 | cr2 | on the ba. |
| 21:53.22 | cr2 | and hima. |
| 21:56.14 | cr2 | you can dd 32MB flash to your disk. ok? |
| 21:57.43 | cr2 | ssh ba cat /dev/mtdblock/0 >ba_pxaflash or something like that |
| 21:59.10 | rob_w | i am still missing mtdblock |
| 21:59.34 | cr2 | after modprobe bluenagel_rom ? |
| 22:00.13 | rob_w | yeah it doesnt pull in mtdblock |
| 22:00.53 | rob_w | done , so now what ? |
| 22:01.47 | cr2 | there are tools on xda-dev that work in wine, like splitrom and dumprom |
| 22:02.16 | rob_w | yeah , right those 32 are now where my provider has his ce + his additions ?!? |
| 22:02.20 | cr2 | what you have now is a decrypted update image distributed by the providers. |
| 22:03.09 | cr2 | the extended rom and the user data are on the g3. |
| 22:03.39 | rob_w | what is that extended rom ? |
| 22:04.03 | cr2 | two fat partitions, the first is password protected. the password is known. and there are tools to unprotect it. |
| 22:04.34 | cr2 | provider customisation crap. "branding", skin and bugfixes. |
| 22:05.11 | cr2 | minor bugfixes and additional (mainly non-m$) software. |
| 22:05.13 | rob_w | ah that is that thing i can "unprotec" .. ok so that is first half of the g3 64 mb |
| 22:05.58 | cr2 | 10mb , imho. the first partition. the second can be just mounted, if we had a g3 driver. |
| 22:06.16 | rob_w | ok , so on a hard reset the bootloader goes in the pxa rom and loads basic ce and then moves to first half g3 and crumbs it full with the rest ?!? |
| 22:06.22 | cr2 | there is a binary driver from a780. kernel 2.4.20 |
| 22:06.41 | cr2 | not exactly. |
| 22:06.52 | rob_w | so before "the rest" happens thats where we can unprotect and intercept taht with a early haret call |
| 22:07.05 | cr2 | the bootloader starts, and sees the wince on the pxaflash. |
| 22:07.08 | cr2 | boots it. |
| 22:07.24 | rob_w | yeah cp15 planned to make a 2.6 loader around that |
| 22:07.34 | cr2 | wince sees the g3 first partion, unlocks it and installs the customisation. |
| 22:07.53 | cr2 | then locks it and unmounts it. |
| 22:08.06 | cr2 | mounts the user second g3 partition. |
| 22:08.35 | cr2 | we can put linux as "wince" on the pxa flash. |
| 22:08.51 | cr2 | but it requires some tricks. |
| 22:09.25 | rob_w | yeah so we are only missing the g3 64mb flash |
| 22:09.25 | cr2 | it is also possible to force the bootloader to ignore "wince" and boot into "debug" environment. |
| 22:09.30 | rob_w | what flash is faster pxa or g3 ? |
| 22:09.33 | cr2 | debug or update or flash. |
| 22:09.46 | cr2 | for reading or for writing ? |
| 22:09.59 | rob_w | lets start with reading ? |
| 22:10.33 | cr2 | i think pxa |
| 22:11.23 | cr2 | g3 also has fancy error correction code. some "patented" shit. |
| 22:11.59 | cr2 | we can do better (in theory), but it will be incompatible with wince. |
| 22:12.03 | rob_w | stupid M-systems , why dont they just through some example code ? |
| 22:12.10 | cr2 | like ext2fs vs fat. |
| 22:12.17 | rob_w | ehehe |
| 22:12.21 | cr2 | or jffs2 vs fat. |
| 22:12.26 | rob_w | ah |
| 22:12.44 | rob_w | that would be nice ! |
| 22:13.34 | cr2 | "intellectual" property ;) they don't do anything themselves. they resell the toshiba nand chips with some their own crappy software above. |
| 22:14.37 | rob_w | but still it seems as they sell well , as they come around my life now multiple times .. |
| 22:14.38 | cr2 | if they will release the sources they are out of the game :) |
| 22:14.55 | rob_w | but back then all code was for DoC was available |
| 22:15.15 | cr2 | not true. is was binary only. |
| 22:15.41 | rob_w | really also this doc2000 and stuff ? |
| 22:15.53 | cr2 | untill the incomplete linux drivers were written. |
| 22:15.55 | cr2 | yes. |
| 22:16.18 | rob_w | hmm.. |
| 22:16.46 | cr2 | they are complete. but for the old small chips. |
| 22:16.59 | cr2 | the linux free drivers. |
| 22:17.08 | rob_w | on my mips dev kit they have some sort of intel flash ,, which they do ship sources |
| 22:17.17 | cr2 | it is like with sd memory. |
| 22:17.21 | rob_w | or maybe not intel, right ;-) |
| 22:17.37 | rob_w | wait a sec |
| 22:20.13 | rob_w | MTD VR4181A: ROMCS device size 32MB at 1e000000, bus width 32bits |
| 22:20.13 | rob_w | <PROTECTED> |
| 22:21.04 | cr2 | it looks also like sdio. it is not rocket science to write a linux sdio driver (for the serial device like gps or bluetooth), but then you will get a lot of publicity like the CSS fiasco. |
| 22:22.09 | rob_w | what was that CSS fiasco ? :-O |
| 22:22.17 | cr2 | DVD |
| 22:22.33 | rob_w | css , wasnt that a copy protection ? |
| 22:23.18 | cr2 | yes. in 1999. at lot of folks wanted to play the matrix movie on linux ;) |
| 22:25.20 | cr2 | css used a primitive cipher. with sdio everything goes about the location of two registers, and some other minor stuff :) |
| 22:26.10 | cr2 | there is a "simplified" spec, where they tell you everything except these small details. |
| 22:27.09 | cr2 | excellent example of what is wrong with the whole "intellectual property" thing. |
| 22:30.17 | cr2 | wow. http://www.services.foxconn.com/store/batchbuy.asp?category.name=Mannual%20Shopping |
| 22:31.45 | cr2 | i wish the hw6515 ipaq was not so ugly ;) |
| 22:33.57 | rob_w | taht is a list ... hehe |
| 22:34.17 | cr2 | look at the lcd prices ;) |
| 22:34.43 | rob_w | so if you like , send your ba over .. i ll sleep soon ,, only some smoke todo ;-) |
| 22:34.48 | cr2 | and you can buy motherboards. if hp will let you do that :lol: |
| 22:35.05 | cr2 | and not in 1000 units. |
| 22:36.24 | rob_w | they propably got some stock .. |
| 22:37.03 | cr2 | only ipaqs, though. |
| 22:40.08 | rob_w | didnt those sdg people release some bootloader for linxu in special ? |
| 22:41.11 | cr2 | yes. we can adapt it for booting linux. but it is probably easier to force htc bootloader boot linux. |
| 22:42.43 | cr2 | it has a lot of pxa270 and hx4700 register-specific stuff, because they had the full docs from hp. and did a lot of clever reserse engineering too. |
| 22:46.22 | rob_w | if i get to choose our chip suppliers on my new projects i will choooose people like this |
| 22:47.42 | rob_w | so. ypi old wuppertal hippi .. i am off for a last smokre and tnhen .. mmmuuuaaahhhh |
| 22:49.05 | cr2 | i will drive to Vienna at the beginning of April. will also visit Munich. |
| 22:53.08 | cr2 | yeah, you are right :) i work in the scientific research since 12 years. |
| 22:54.13 | rob_w | cool ,, lets keep that munich visit in mind .. do you have spare time theere |
| 22:55.49 | cr2 | yes. i'd like just to visit my friends there. i lived there 5 years. |
| 22:58.05 | rob_w | ok .. cool .. cu .. night |
