| 17:28.12 | seb82 | hey, I've got a question not related to HTC but this is the only channel I could think of were to ask... |
| 17:28.23 | phh | go ahead |
| 17:28.35 | Alex[sp3dev] | phh: stop typing my thoughts! |
| 17:28.36 | seb82 | My dad owns a very old hp ipaq... with a samsung processor... |
| 17:28.53 | phh | Alex[sp3dev]: sorry about that |
| 17:28.56 | seb82 | from wot I have read around it should be able to run linux, atleast the kernel... |
| 17:29.07 | seb82 | so i'm attempting to build a kernel with debian... |
| 17:29.25 | Alex[sp3dev] | seb82: which model? i think *old* devices were only supported by handhelds.org kernel |
| 17:30.04 | seb82 | alright so far so good... when gitting the source as stated on htc-linux.org... I found out that the processor is suppored in arch/arm/configs/ |
| 17:30.21 | seb82 | It's a rx1950 |
| 17:30.33 | seb82 | the processor is a s3c2442... |
| 17:30.53 | Alex[sp3dev] | okay.. i think it is supported by mainline since not so long ago |
| 17:31.43 | seb82 | yeah it's also stated in the arch/arm/ folder with mach-s3c2442 |
| 17:32.15 | seb82 | I only have to clue with branche to check out... |
| 17:32.48 | Alex[sp3dev] | where are you getting the source from? i advise that you get vanilla linux (from github) and build rx1950. it is in mach-s3c2440 |
| 17:33.05 | seb82 | i need mach-s3c2442 |
| 17:33.28 | seb82 | I got the source from git://git.linuxtogo.org/home/groups/mobile-linux/kernel.git |
| 17:33.57 | Cotulla | remember s3c2442: never saw such slow and @$*(&^@*$& cpu |
| 17:34.10 | Cotulla | OMAP850 was faster |
| 17:34.34 | Alex[sp3dev] | that is too old. i personally advise you to use mainline, take a defconfig for any s3c2440/42 board and enable rx1950 in the config. sound and other stuff was added like a month ago so the code is tested and working |
| 17:34.50 | Alex[sp3dev] | Cotulla: i had 2410 once.. oh well |
| 17:35.28 | Cotulla | but I am working with s3c2410 at the current moment too :o |
| 17:35.36 | Cotulla | just realized it :) |
| 17:35.46 | Alex[sp3dev] | what the fuck? |
| 17:35.54 | Cotulla | MS DeviceEmulator |
| 17:35.59 | Alex[sp3dev] | oh |
| 17:36.04 | Alex[sp3dev] | it sucks |
| 17:36.06 | Cotulla | S3C2410 emulation |
| 17:36.08 | Cotulla | no |
| 17:36.09 | seb82 | Alex[sp3dev] where can I get that mainline? |
| 17:36.10 | Cotulla | it rulezz |
| 17:36.11 | Alex[sp3dev] | it is even slower than a real device |
| 17:36.19 | Cotulla | it not so slow |
| 17:36.21 | Cotulla | and with JIT |
| 17:36.49 | Cotulla | useful for debugging |
| 17:37.02 | Alex[sp3dev] | Cotulla: well, it is unusable for gaming. once i had no pda but only a smartphone without touchscreen and i used the emulator to play a game. it sucked |
| 17:37.06 | Cotulla | but it only supports up to ArmV5 |
| 17:37.23 | Alex[sp3dev] | seb82: github.com/torvalds , download linux from there.. |
| 17:37.26 | Cotulla | no proper emulators with ARMv7 for now |
| 17:37.27 | Cotulla | :( |
| 17:37.41 | Alex[sp3dev] | Cotulla: it is probably cheaper to use native hardware today |
| 17:37.48 | seb82 | wot tools do i need? I'm not a long time developer... |
| 17:37.50 | Cotulla | don't think so . . . |
| 17:38.01 | Cotulla | I can reset emulator each minute |
| 17:38.04 | Cotulla | without issues |
| 17:38.07 | Cotulla | :) |
| 17:38.11 | Alex[sp3dev] | Cotulla: with jtag you can do the same and even more |
| 17:38.22 | Cotulla | more ... it's not always more |
| 17:38.25 | Alex[sp3dev] | seb82: you need a toolchain. use codesourcery g++ lite |
| 17:38.38 | Cotulla | I am interesting in log output |
| 17:38.45 | Cotulla | so there UART console |
| 17:38.50 | seb82 | was already working on this: http://wiki.debian.org/BuildingCrossCompilers |
| 17:39.25 | Alex[sp3dev] | Cotulla: with jtag you can hook any memory address, you know. and all debug board have UART. actually I doubt you can emulate a modern A9 with full speed |
| 17:39.41 | Cotulla | with jtag yes |
| 17:39.50 | Cotulla | but it may need more stuffs for os |
| 17:40.00 | Cotulla | so I am happy with clear ideas & console output |
| 17:40.18 | Cotulla | and I don't have jtag :( |
| 17:40.53 | Cotulla | okay it's time to ask a question :D |
| 17:41.02 | seb82 | I'm on github but erm... wehre do I download it? |
| 17:41.03 | Alex[sp3dev] | seb82: download EABI or GNU/Linux toolchain from https://sourcery.mentor.com/sgpp/lite/arm/portal/subscription?@template=lite . not that you cannot build one yourself, but this one is known to be working and everyone here is using it |
| 17:41.38 | Alex[sp3dev] | seb82: go to github.com/torvalds, click linux and you'll see the downloads button |

| 17:49.15 | Cotulla | Linux too |
| 17:49.34 | Alex[sp3dev] | actually linux can run on lower resources (if you use qtopia/opie). but there is even less software for them than for winmo |

| 18:16.22 | Cotulla | wtf |
| 18:16.29 | Cotulla | maemo megoo |
| 18:16.36 | Alex[sp3dev] | n900 was a good phone. and N9 is good as well. n950 is n9 with keyboard |
| 18:16.43 | Cotulla | why not keep maemo and develop it |
| 18:16.43 | seb82 | but some of they're phone builds (exterior that is) were nice... like the 8210 and 8310 |
| 18:16.55 | Cotulla | they are software whores |
| 18:16.56 | Cotulla | :D |
| 18:17.39 | seb82 | I wonder how long M$ can keep it's market place... |
| 18:17.42 | Alex[sp3dev] | Cotulla: because maemo was close-sourced and meego source code is available. besides, meego's aim was to develop together with intel. but actually it was stupid to switch from deb to rpm |
| 18:18.00 | Cotulla | and who need source? where sound of samsung badas? or of android honekomb? |
| 18:18.15 | Cotulla | binary modules better for customization |
| 18:18.49 | Cotulla | my personal opinion it was stupid idea to do it so |
| 18:18.52 | Alex[sp3dev] | afaik n900 was mostly popular around geeks who needed source.. i doubt ordinary user would ever buy it at all |
| 18:19.05 | Cotulla | the best idea was to develop new os from scratch |
| 18:19.09 | Cotulla | or on some kernel |
| 18:19.13 | Cotulla | Linux/L4/etc |
| 18:19.16 | Alex[sp3dev] | no, it is a stupid idea |

| 18:19.45 | Alex[sp3dev] | there are like 10 or more 'new OSes' and all incompatible between each other |
| 18:19.47 | Cotulla | need at the market |
| 18:20.10 | Cotulla | I means it's different things: develop for geeks at hobby time and develop for final product |

| 18:20.48 | Alex[sp3dev] | Cotulla: X11 provides support for a lot of applications. but actually both meego and ubuntu are working on a new graphics stack (wayland) which will reduce the latencies (by reducing the number of image copyings) |

| 18:37.15 | Cotulla | current cards are 32/64 Gb |
| 18:37.22 | phh | I'd guess it's more because exFAT can't handle more than 2TB :D |
| 18:37.24 | Cotulla | so again `20 times bigger |
| 18:37.33 | Cotulla | maybe |
| 18:37.46 | phh | Cotulla: well first joke was SDHC |
| 18:37.47 | Cotulla | it's same |
| 18:37.51 | phh | from 2Gb to 32GB |
| 18:37.53 | phh | oh well it's *16 too |
| 18:37.58 | Cotulla | lol |
| 18:38.09 | Cotulla | like u choose variable type for size inside program |
| 18:38.19 | Cotulla | UInt32 not enough? |
| 18:38.27 | Cotulla | why UInt64 enough? |
| 18:38.30 | phh | uint128 will always be enough ! |
| 18:38.37 | Cotulla | make it UInt256 with complex arithmetic |
| 18:38.46 | phh | well unless we can travel through universes |
| 18:38.49 | Cotulla | somebody said: "640K is enough for everyone" |
| 18:38.50 | Cotulla | :D :D |
| 18:39.00 | Cotulla | and nobody had doubts |
| 18:39.00 | Cotulla | :D |
| 18:39.20 | Cotulla | same with UInt128 |
| 18:39.37 | phh | well, iirc, the entropy generated by storing 2^64bytes will make the oceans vaporize. |
| 18:39.38 | Cotulla | but most people choose 64 bits for size |
| 18:39.42 | phh | so i'd say i'ts safe. |
| 18:39.46 | Cotulla | now |
| 18:39.55 | Cotulla | because it's enough for current moment |
| 18:39.59 | phh | ah no that's 2^128 |
| 18:40.26 | Cotulla | then we will got new CPUs which will handle 2^256 operations per second |
| 18:40.39 | phh | that's kind of unlikely. |
| 18:41.07 | Cotulla | yeah :( if we look how people degrade last years :( |
| 18:41.33 | Cotulla | but maybe not we |
| 18:41.35 | Cotulla | but robots |
| 18:41.40 | Cotulla | androids, zooroids and etc |
| 18:41.46 | Cotulla | :P |
| 18:42.59 | Cotulla | okay |

| 19:29.29 | seb82 | right I got it all hours ago... now how do I compile this kernel? |
| 19:30.52 | Alex[sp3dev] | like here http://forum.xda-developers.com/showpost.php?p=15835606&postcount=87 |
| 19:31.04 | seb82 | Alex[sp3dev] thx |
| 19:31.25 | Alex[sp3dev] | but use the defconfig from some s3c2440 device and do a make menuconfig before doing make zImage and select your pda in the system type and also sound codec in drivers |
| 19:32.35 | seb82 | kk I'll see where I can get this going... |
| 19:34.37 | seb82 | I have installd the toolchain |
| 19:34.47 | seb82 | but do I need the light or the arm eabi? |

| 20:46.16 | Alex[sp3dev] | better leave it to yourself and become a developer ;) |

| 20:48.19 | Cotulla | now u an enslave of Blackstone :P my celebrations! |
| 20:48.21 | zagitta | surely i started studying computer sience but let's not get ahead of ourselves here :P |
| 20:48.55 | Alex[sp3dev] | this is not science, it is engineering |
| 20:48.57 | Cotulla | *congratulations |
| 20:49.12 | Cotulla | this is not engineering, it's holy-shit-@*(#$@^$@$^ |
| 20:49.49 | zagitta | also i'm not masochistic enough to write kernel stuff :P |
| 20:50.07 | Cotulla | heh |
| 20:50.11 | Alex[sp3dev] | zagitta: you get a perfect feeling of it ;) |
| 20:51.32 | Cotulla | yeah, from my sentence :D not about " engineering " bulalal |
| 20:52.32 | Cotulla | guys, will u buy my bulala cpus?! |
| 20:53.20 | zagitta | damn you Alex[sp3dev], now i'm actually considering becomming a developer... but there's just soooo much bloody knowledge about hardware and native programming languages i lack that it would be one heck of a uphill battle to learn |
| 20:53.51 | Cotulla | forgot all. u need start from clear things :) it's kernel development, at the end. |
| 20:54.25 | Alex[sp3dev] | zagitta: if you want to make a carreer in CS/SE, you'll have to learn *everything about computers*. the order in which you will study things may differ |
| 20:54.26 | zagitta | lol who needs an aprentice? :p |
| 20:55.26 | Cotulla | A shit fed, beer cooled journeyman operated device. Can be used for haulin, tuggin, luggin, or any other unjourneyman like task. Can be found at the bottom of the ocean with another sub species of it's type otherwise known as wale shit. |

| 20:56.43 | Cotulla | x1? |
| 20:56.50 | Alex[sp3dev] | but i have fixed framebuffer blanking using linux ioctls without android's early suspend |
| 20:57.04 | zagitta | Alex[sp3dev]: true but i just started last week and honestly the "convert 4000 seconds into the sentence: "x hours, x minutes, x seconds" isn't exactly very stimulating ;) especially not when you already know all the programming shit except for pointers that still confuse me a tad |
| 20:57.07 | Cotulla | power always hard |
| 20:57.13 | Alex[sp3dev] | time to remove android crap from kernel |
| 20:57.20 | tmzt | guys I'm working on a bootloader for newerr msm devices based on lk |
| 20:57.25 | tmzt | in #msm-bootloader |
| 20:57.29 | Alex[sp3dev] | tmzt: damn you |
| 20:57.39 | Cotulla | tmzt for which devices? |
| 20:57.47 | Alex[sp3dev] | tmzt: i've ported LK to msm7200A wince phones ;) |
| 20:57.48 | tmzt | Cotulla: primarially touchpad |
| 20:57.53 | Cotulla | hehe |
| 20:57.54 | Cotulla | clear :) |
| 20:57.55 | Alex[sp3dev] | #j msm-bootloader |
| 20:57.58 | Alex[sp3dev] | damn |
| 20:58.16 | Cotulla | and what there in msm-bootloader? |
| 20:58.16 | tmzt | not hd2 :) |
| 20:58.16 | tmzt | it's just getting started |
| 20:58.49 | tmzt | Alex[sp3dev]: you have aboot/adb working? |
| 20:58.58 | tmzt | where is your tree? |
| 20:59.06 | Cotulla | seems found new place to troll |
| 20:59.18 | Alex[sp3dev] | tmzt: yes, and on rhodium guys are running android from nand with it |
| 20:59.29 | tmzt | sweet |
| 20:59.42 | Cotulla | tmzt, are there gotta be anything intersting? |
| 20:59.43 | Alex[sp3dev] | mine is https://gitorious.org/lk-msm7200a-htc-wince/lk-msm7200a-htc-wince for kovsky |
| 21:00.01 | Alex[sp3dev] | abel has his port based on another lk tree with my hacks https://gitorious.org/~acl/lk-msm7200a-htc-wince/acls-lk-msm7200a-htc-wince |
| 21:00.02 | zagitta | wonders how he should get started |
| 21:00.20 | tmzt | Cotulla: we are working with the apq8060 surf board from codaurora |
| 21:00.30 | tmzt | the board port for that |
| 21:00.39 | Cotulla | there no config for that in LK? |
| 21:00.45 | *** join/#htc-linux helicopter88 (~helicopte@host126-231-dynamic.45-79-r.retail.telecomitalia.it) |
| 21:00.49 | tmzt | yeah for the surf |
| 21:00.56 | tmzt | we are porting that to the tp |
| 21:01.00 | Cotulla | oh |
| 21:01.10 | tmzt | chainloaded from bootie (also basedo nlk but closed source) |
| 21:01.13 | Cotulla | but it should be easy no? |
| 21:01.15 | Alex[sp3dev] | zagitta: learn C and get comfortable with pointers, strings and files first. and learn yourself unix shell and some scripting languages (perl, python and ruby). just so that you feel comfortable in userland and can write apps for yourself |
| 21:01.29 | tmzt | *dst = *src ; :) |
| 21:02.47 | Cotulla | lol |
| 21:03.02 | Alex[sp3dev] | tmzt: tbh, my main problems with LK were that 1. old wince didn't use smem and rpc IDs compatible with android AMSS and 2. most of power management and usb was hard-coded for newer QSDs and i had to rewrite it to make it possible to support several boards at the same time |
| 21:04.58 | Cotulla | tmzt, android already fully ported to touchpad? |
| 21:05.08 | zagitta | Alex[sp3dev]: thanks! |
| 21:05.29 | tmzt | Cotulla: cm is doing a full port |
| 21:05.41 | tmzt | they aren't sharing with anybody yet though |
| 21:06.03 | phh | ah they are doing it ? I thought they aborted |
| 21:06.20 | phh | (and i'd like to hear jonpry's point of view) |
| 21:06.57 | Alex[sp3dev] | dunno about jonpry but my point of view is that with a 10 inch screen and a dual-core cpu you're better off running ubuntu |
| 21:07.01 | tmzt | he's in #msm-bootloader too at the momnt |
| 21:07.13 | Cotulla | how is jonpry's boat and he jonpry? |
| 21:07.18 | tmzt | ? |
| 21:07.45 | Alex[sp3dev] | tmzt: jonpry has a boat and Cotulla uses that to authenticate jonpry ;) |
| 21:07.54 | Cotulla | right |
| 21:08.07 | tmzt | ah |
| 21:08.08 | Cotulla | :D |
| 21:08.10 | tmzt | ok |
| 21:08.30 | Cotulla | tmzt, did u even put some smiles to the text? :P |

| 21:17.48 | Alex[sp3dev] | cr2_: hi |
| 21:18.02 | cr2_ | hi phh Alex[sp3dev] |
| 21:18.43 | cr2_ | i was hacking one more undocumented arm7tdmi controller |
| 21:19.18 | phh | you love that uh ? |
| 21:19.53 | cr2_ | heh |
| 21:20.04 | cr2_ | i have reached my goals |
| 21:20.06 | phh | well arm7 was good time, everything was easy |
| 21:20.15 | phh | well |
| 21:20.17 | phh | easy is all relative |
| 21:20.23 | cr2_ | need to port linux to my old pxa255 pda |
| 21:20.31 | tmzt | whihc? |
| 21:20.32 | phh | "need" is all relative too :D |
| 21:20.40 | Cotulla | phh, ur tegra have two arm7 no? have fun with them :P |
| 21:20.51 | cr2_ | phh: the problem is not arm7, but the peripherals |
| 21:20.54 | phh | Cotulla: two ? i was aware of only one |
| 21:21.05 | Cotulla | dunno |
| 21:21.13 | Cotulla | 8660 has two :P |
| 21:21.16 | phh | cr2_: omap4 is 2, but tegra is only one i think |
| 21:21.23 | phh | erf that was for Cotulla |
| 21:21.26 | phh | Cotulla: seriously ?!? |
| 21:21.28 | cr2_ | Cotulla: it's gps chipset from ublox |
| 21:21.32 | phh | they all want in that crazy nses :( |
| 21:21.43 | tmzt | ah |
| 21:21.43 | Cotulla | maybe there standard IPCores used? |
| 21:21.47 | Cotulla | like uart from arm |
| 21:21.47 | tmzt | is that used in gta02? |
| 21:21.48 | Cotulla | and etc |
| 21:22.09 | phh | Cotulla: i think they are just using shared memory |
| 21:22.28 | cr2_ | tmzt: gta uses ublox4, which is more or less obsolete (but very nice chip) |
| 21:22.52 | cr2_ | tmzt: the modern devices are ublox5 and 6 |
| 21:22.53 | tmzt | how you been? |
| 21:23.35 | cr2_ | ? |
| 21:23.52 | tmzt | how have you been? :) |
| 21:23.54 | cr2_ | i'm looking for navigon p9611 |
| 21:23.58 | tmzt | nvm |
| 21:24.14 | cr2_ | missed it on ebay in july ;) |
| 21:24.34 | cr2_ | tmzt: i'm fine, but need to work a lot. |
| 21:24.47 | cr2_ | next week driving to northern Norway |
| 21:25.45 | cr2_ | Alex[sp3dev]: did you tell me some time ago about the (non-android) exploit for 2.6.17 ? |
| 21:27.02 | cr2_ | tmzt: what do you think about meizu m9 ? |
| 21:29.14 | Alex[sp3dev] | cr2_: maybe it was me, but dunno. not sure i have the link but it is easy to find it on google |
| 21:29.48 | cr2_ | Alex[sp3dev]: i think it did not compile |
| 21:30.00 | cr2_ | it was some collection of code |
| 21:31.20 | cr2_ | phh: meizu m9 uses ublox6 chip. i'm wondering how they have managed to put the weird android libgps on top of such a fine chip :) |
| 21:31.42 | phh | cr2_: ? there is an example simple NMEA libgps parser |
| 21:32.10 | cr2_ | phh: it's capable of agps too |
| 21:32.18 | cr2_ | you can't do it with nmea |
| 21:32.42 | Cotulla | what is baseband in meizu m9 ? |
| 21:32.45 | phh | cr2_: how ? |
| 21:32.53 | phh | cr2_: i mena xtra.bin + just push position ? |
| 21:33.48 | cr2_ | xtra.bin is some patented qualcomm thing |
| 21:34.02 | cr2_ | nobody else uses it |
| 21:34.36 | phh | ah ok |
| 21:34.38 | phh | so what is it ? |
| 21:35.57 | cr2_ | everybody invents something their own |
| 21:36.05 | cr2_ | and hides the real raw data |
| 21:36.35 | cr2_ | getting to the raw data was one of my goals. |
| 21:36.52 | phh | ah ok |
| 21:36.52 | cr2_ | ublox seems to be the best in this area |
| 21:37.16 | cr2_ | i don't even think doing something like that with qualcomm |
| 21:37.54 | cr2_ | omg. no pxa2xx support in haret... |
| 21:38.07 | phh | you've got to fix that. |
| 21:38.20 | cr2_ | yes |
| 21:39.26 | cr2_ | p9611 is pxa27x though |
| 21:40.43 | cr2_ | phh: i also have a gps logger with at91* |
| 21:41.39 | cr2_ | phh: linux is more or less possible on that thing |
| 21:41.57 | cr2_ | but it is a nice arm7 controller too |
| 21:43.00 | cr2_ | s/possible/impossible/ hehe |
| 21:43.26 | phh | he heard "less" |
| 21:43.28 | cr2_ | so a lot of old good hardware is lying around |
| 21:43.28 | phh | so you'll do it :D |
| 21:43.47 | cr2_ | phh: it's easier to install some free rtos on it |
| 21:44.15 | cr2_ | the thing parses nmea, and writes the log on the sd card |
| 21:44.53 | phh | ah logger in that sense |
| 21:44.54 | phh | ok |
| 21:44.54 | cr2_ | i can't imagine a more stupid and primitive design. |
| 21:45.00 | cr2_ | wintec wbt-202 |
| 21:45.08 | phh | cr2_: yeah well, chinese are stupid, aren't they ? :p |
| 21:45.24 | cr2_ | not stupid |
| 21:45.50 | phh | lazy ? |
| 21:45.52 | cr2_ | but not very creative, when it comes to programming |
| 21:46.27 | cr2_ | they do what is said to be done |
| 21:46.31 | cr2_ | and nothing more |
| 21:46.54 | phh | anyway how would you do that ? |
| 21:46.55 | phh | an ASIC ? :D |
| 21:47.28 | cr2_ | no, the hardware itself is ok |
| 21:47.59 | cr2_ | but they simply bought a license for a rtos |
| 21:48.17 | cr2_ | only to parse nmea, and write 3 columns of data to the sd |
| 21:48.27 | phh | ah ok |
| 21:48.43 | cr2_ | they could have easily taken a free one |
| 21:48.49 | cr2_ | there are several of them |
| 21:49.02 | phh | it's not like they pay the licence any way. |
| 21:49.26 | cr2_ | and once they already have a rtos, they could have do much more with this hardware |
| 21:49.34 | Cotulla | most free RTOS with different issues ;) |
| 21:49.50 | phh | cr2_: it's a *gps logger* |
| 21:49.55 | phh | what do you want to do with it ? :D |
| 21:50.03 | cr2_ | phh: i think they've really paid |
| 21:50.45 | cr2_ | Cotulla: i think they could have even taken the free code from atmel for a logger ;) |
| 21:50.56 | phh | indeed |
| 21:51.07 | Cotulla | for example, the one which I am using, put zero to CPSR after fail to unlock mutex. |
| 21:51.16 | Cotulla | I spent 2 hours to debug this pfff |
| 21:51.46 | cr2_ | hehe |
| 21:51.50 | Cotulla | :( |
| 21:52.27 | Cotulla | but ofcourse it small, so it's possible to check / find issues by hands. |
| 21:54.42 | cr2_ | this is going to be my next fun project: http://www.u-blox.com/en/press-and-events/press-release-archive/1147-u-blox-to-demonstrate-glonass-positioning-at-telematics-detroit.html |
| 21:54.54 | cr2_ | to find and flash such firmware :) |
| 21:55.22 | Cotulla | GLONASS lol |
| 21:56.04 | Alex[sp3dev] | cr2_: do you want to receive signal from russian underwater satellite network? xD |
| 21:56.18 | Cotulla | :D :D |
| 21:56.21 | Cotulla | Alex _1 |
| 21:56.21 | Cotulla | +1 |
| 21:56.53 | cr2_ | well, there are some satellites in space too |
| 21:57.44 | cr2_ | the flash was put by ublox for a galileo update |
| 21:57.48 | cr2_ | but it seems to be in an even worse stage |
| 21:58.38 | cr2_ | glonass is going to be a pita for this chipset |
| 21:58.53 | cr2_ | because of the 24 frequencies for tracking |
| 21:59.07 | cr2_ | instead of 1 |

| 22:02.22 | cr2_ | so it's easier to get a lock for the correlator |
| 22:02.46 | cr2_ | channel=frequency channel |
| 22:02.56 | phh | hum btw, how is handled the doppler effect in standard gps unit ? |

| 22:03.39 | cr2_ | phh: the speed and position is known from the ephemeris |
| 22:04.05 | phh | yeah ok, but i mean it's changing the PLL dynamically to adjust on the good frequency ? |
| 22:04.20 | cr2_ | i guess so |
| 22:04.43 | cr2_ | the chipset was designed for gps/galileo (=1 frequency) |
| 22:04.44 | phh | ok |
| 22:07.21 | cr2_ | phh: actually the tracking block is separate from the acquisition on ublox6, so who known how they do it. |
| 22:07.57 | phh | i thought you know everything :( |
| 22:09.28 | cr2_ | phh: even getting the ephemeris data is "premium feature" |

| 22:10.47 | cr2_ | phh: but the us/taiwanese chipsets are even worse in this area. they provide nmea only, or crippled and slow raw data |
