<Mehhh> Is sunxi-bsp the better way to go?
<libv> Mehhh: the better way to go for what?
<libv> Mehhh: for getting a 3.8 kernel up and running?
rellla has joined #arm-netbook
Ershov has quit [Read error: Connection reset by peer]
<Mehhh> no, for the optimizations in the 4.7
<Mehhh> gcc
<Mehhh> oh wait
<Mehhh> sorry wrong thing, better way to go for managing the entire thing and creating the image
<Mehhh> better question, which path do you take? :)
<libv> i wrote down what i did in firststeps
<libv> which i think by now you should've been able to execute several times over already
<Mehhh> yes
<Mehhh> did, then i saw that
<Mehhh> i wondered the difference in management (as in, why)
Ershov has joined #arm-netbook
<libv> Mehhh: does the difference matter to you once you have succeeded?
<Mehhh> Not really
<libv> the bsp thing is about convenience
<Mehhh> oh, that's what i figured
<Mehhh> gotcha
<libv> which is important for some people
<libv> for someone like me, having control over how to build the kernel, is quite important
<libv> Mehhh: but again, why does all of this matter?
<libv> Mehhh: matter to you personally
<libv> you've been in this channel for quite a while now
<libv> surely you've succeeded in getting your device up and running by now
<Mehhh> yes, but i'm also OCD
<Mehhh> and doing a writeup for other people not related to the channel
* libv checks RecentChanges in the wiki
<libv> where is it?
<Mehhh> In LibreOffice
<Mehhh> i don't understand what you're asking
<libv> with me it took a while until things were working for me
<Mehhh> oh, haven't checked all that yet, just amde sure it boot
<libv> first, because firststeps was not there yet, secondly because the psu i used was underpowered and the device was not stable at all
<Mehhh> It's easier to go back and edit
<Mehhh> ahhhh
<Mehhh> mk802?
<libv> no, mele
<Mehhh> Oh gotcha, yeh i'm having to figure out certain portions for mk802
<libv> once the thing was working, i asked hno the right questions, and hno gave some stellar answers, and the A7HD tablet was supported in no time
<Mehhh> Hell yeh
<libv> now, what good is an office document going to do anyone?
<Mehhh> I'm handing the project off to someone else, I just need this done so i can have an arm netbook completed before i go on vacation
<libv> so have you actually been able to get anything real booted on this device?
<Mehhh> yes
<Mehhh> i have to fork this into my personal use and one for the project
<libv> ok, so you have the .fex and uboot figured out
<Mehhh> yes
<libv> have you sent this in to the ml?
<Mehhh> uboot was never a problem, i'm worried more about speed and support and the modules
<Mehhh> for one specific device
<libv> have you documented this device further on the wiki?
<libv> or are you just using the mk802?
<Mehhh> just the mk802
<Mehhh> internal lapdock mod
<Mehhh> The project owner can't get his working (two mk802's), so i'm saying screw it and just DIY.
<Mehhh> I'm just looking at anything extra that may get shoved in, and/or config support i want
<libv> ok, why not just do what i have done on projects: hand over a known good sd card which should not be touched, store a dd-ed image somewhere, and point the person taking over to the FirstSteps howto for further info on how this was created
<Mehhh> I'll most likely being doing the kernel updates at a later point
<libv> if firststeps is not good enough, then fix it
<Mehhh> i'll prob send him the sd card
<Mehhh> hmmm, i may
<libv> i personally cover more bases.
<Mehhh> Didn't know if i was allowed to
<libv> it's a wiki.
<libv> if we do not like your changes, we fix them
<Mehhh> I mean.... not in terms of possible but in terms of
<Mehhh> favorable / un
<Mehhh> ah
<Mehhh> kk
<Mehhh> the malis on the latest pull are the ones from the video, correct?
<libv> what malis, what pull, what video?
<Mehhh> your cube
<Mehhh> @ cnx
<libv> that runs on my lima driver code
<Mehhh> I mean, is that included already in the latest pull / wiki
<libv> latest pull of what?
<Mehhh> i cloned the entire repo
<libv> which repo?
<Mehhh> i didn't know if the changes were private / testing or on there
<Mehhh> the entire thing
<libv> the entirety of github.com?
<Mehhh> sunxi
<Mehhh> github.com/linux-sunxi/
<Mehhh> cloned
<Mehhh> all sub-dirs
<Mehhh> I know what it is
<libv> you clearly don'T
<libv> because your questions make absolutely no sense
<Mehhh> I clearly do. I was asking it if was linked already
<Mehhh> or sep
<libv> it has always been separate
<Mehhh> Cool, thank you for answering my question.
<libv> it's not useful for normal users of sunxi
<libv> and it is supposed to be much more general than just sunxi
<libv> sunxi is just the perfect platform for lima development at this time
<Mehhh> Look, I don't know if i said something or
<Mehhh> phrased something incorrectly or in a way that isn't kosher.
<libv> it is the way you ask questions
<Mehhh> I'm just getting it done
<libv> they seem to be without a clear goal, and are strangely phrased, and my requests for quantification gets more wishy-washy answers
<Mehhh> If me being casual offends you, you don't have to respond.
<Mehhh> I'm really not here to pick fights.
<Mehhh> The goals aren't clear because I have two different sets of goals
<Mehhh> Your driver is obviously nice, and works well.
<Mehhh> Well, good enough for the acceleration that will be expected of the image.
<libv> it's not even a driver yet.
<Mehhh> and then some
<Mehhh> Looks like one to me, hince this image vs the other two
<Mehhh> I'm trying to pull a Ford here, not a Ferrari.
<libv> in case you were not paying attention, the cube is running on limare, a special lib meant to gradually build up knowledge of the mali hw, there are some gles tests, and there are corresponding implementations using the limare library, which gets adapted accordingly
<libv> q3a is not running on top of limare (yet)
<libv> it runs on the arm binaries
<Mehhh> i am paying attention
<libv> the arm binaries are a complete opengles[12] driver stack
<Mehhh> Nothing new I didn't read the past few days
<Mehhh> Brb
<libv> then the questions you've been asking just now were not in correlation with the knowledge you supposedly already acquired
<Mehhh> You say automobile, I say car.
<Mehhh> Doesn't matter
<oliv3r> ...

<RaYmAn> one line would clearly have been enough :P
<jquip> sorry
<jquip> yes
<RaYmAn> however, it sounds like you're using wrong kernel version vs drivers
<jquip> now that would be highly unlikely... 3.0.52 both...
<RaYmAn> the UMP log thing means *userspace* graphics drivers try to talk to the kernel in a way that the kernel doesn't know (essentially)
<jquip> ahhh! interesting... go on...
<RaYmAn> that's about it. Wrong version userspace drivers vs kernel drivers.

<mnemoc> focus_it: I'm still trying to get a reply about buying a devkit for allwinner's cortex-a7... I suppose normal manufacturers might have the same problem
<mnemoc> unless allwinner/wits itself is designing the PCBs and making the software
<mnemoc> focus_it: can you add a page in linux-sunxi.org for the A31 ?
<focus_it> eek how?
<mnemoc> it's a wiki... register and write :)
<focus_it> will try
<mnemoc> it's pretty sad they abandoned mali
<focus_it> mnemoc: how come other companies have already built A31 while you can't get dev kit???
<Mehhh> Do we know for certain that's the case in the A40?
<RaYmAn> focus_it: I suspect it's a lot easier to get it if you produce stuff next door or similar
<mnemoc> Mehhh: there is no such thing as the A40
<RaYmAn> rahter than across the internets
<RaYmAn> mnemoc: what do they use isntead of mali?
<mnemoc> Mehhh: there was tons of "speculation" about the sun6i. device manufacturers made up the A40 and A15X to refer to the "unnamed" sun6i chip
<Mehhh> ah ah
<mnemoc> RaYmAn: PowerVR SGX544
<focus_it> RaYmAn: I agree - face to face is very important in China. I advise everyone, if you want to do business in China, make a point of visiting the factory before drawing up biz plans
<mnemoc> even lkcl ended up getting the A10 PCB designed by wits
<mnemoc> with A31 might be the same
<mnemoc> so no need for manufacturers to have a devkit
<mnemoc> they just pay allwinner/wits to do all the work
<focus_it> mnemoc: that sounds interesting - so any idea how much money they charge - is it like high price or a typical CN design house price?
<mnemoc> I guess it's competitive with other chinese design houses
<RaYmAn> focus_it: there's probably a reason 95% of a10 devices are identical
<mnemoc> but the key for allwinner is cheap production
<mnemoc> they only "adjust" the reference design

<mnemoc> Mehhh: no
<Mehhh> rats
<mnemoc> they don't do odd variants
<mnemoc> the chips have very distintive targets, and so pin compatibility isn't interesting
<Mehhh> I've been noticing that. I was looking for a stick verson that was slightly longer with a more narrow PCB
<Mehhh> didn't find it
<mnemoc> the A10s was made for that

<RaYmAn> antonl: yes
<focus_it> mnemoc: confused - more info about which soc?
<mnemoc> A31
<antonl> Any hope of completely replacing the chromeos with linux? Is internal SSD much faster than a class 10 SD card?
Ershov1 has joined #arm-netbook
<focus_it> mnemoc: the two links there provide the only information I have - is there more that can be found from Allwinner site?
<mnemoc> focus_it: never mind
<focus_it> yes

<mnemoc> focus_it: I was asking you to add information to the wiki, not links
<mnemoc> but don't worry
<focus_it> love to as I get prepare more stuff
<RaYmAn> antonl: hm, ssd should be pretty fast, but I haven't run any proper tests myself. You can easily replace default os with linux - you can also boot directly off SD or USB for dev/multiboot
Ershov1 has quit [Client Quit]
<antonl> so, the bootloader is unlocked? I remember many problems of now-sold AC100, regarding bootloader issues.
Ershov has quit [Ping timeout: 260 seconds]
<RaYmAn> yes, it's unlocked. You need to enable dev mode to boot alt. os, but it's easy
vinifm has joined #arm-netbook
<RaYmAn> antonl: incidentally, it's also pretty much unbrickable (without hardware mods). You can always boot a chromeos recovery image and reflash the entire device
<Jef91> hey RaYmAn do you know if there are any pre-built images for the chromebook yet?
<antonl> So, currently we are bound to the kernel distributed in the official chreomeos image? What's with hw video decoding?
<RaYmAn> no, once in dev mode you can flash/boot whatever kernel you want (it just needs to be signed with the dev key)
<rastko> rz2k: Where should I post a patch for ili210x touchscreen?
<RaYmAn> I don't think hw video decoding is there yet, but I don't know
<Jef91> Alrighty RaYmAn. It always confuses me why people don't just create a .img file of their working bootable SD card instead of making people follow long HOWTO
<Jef91> s
<RaYmAn> probably because it's rather easy to do and distributing a fairly large image is a pain? :)
<RaYmAn> there is uhm, a project where you download & run a script and it prepares the chromebook and installs linux
Ershov has joined #arm-netbook
<Jef91> RaYmAn: not really. I host images for serveral ARM devices all on source forge free of charge
<antonl> So, have samsung released the kernel sources that were used to build the chromebook kernel?
<RaYmAn> of course

<slapin> hi, all!
<Turl> hi slapin
<slapin> is there somewhare I can order chromebook? looks tasty...
<slapin> or all are gone by now?
<Turl> google play store? just a guess though
<mnemoc> amazon
<libv> Turl: it will spin the cube companion for you
<libv> Turl: it should be easily buildable on a normal linux
<Turl> talking about the cube, I saw some benchmarks on the wiki I think
<Turl> it was like a lot of fps for 720p and like.. 2-3 for 1080p
<Turl> libv: why is that?
<libv> Turl: first off, 1080p is 2.25 the amount of data
<libv> times even
<libv> so the 40fps for normal quake already becomes like 18fps
<Turl> hrm, not the cube but quake
<libv> then, add in the fact that this data not only needs to go somewhere
<libv> it needs to come from somewhere as well
<libv> there's a load of texture lookups that need to be done for quake
<Turl> 40 fps on 720p, 5 fps on 1080p
<libv> so if you factor in that these texture lookups will be anywhere from 1 to 4pixels (even mipmapped) or even much more for a complex scene...
<libv> and you're suddenly pulling in a lot of data across the memory subsystem
<rz2k> <rastko> rz2k: Where should I post a patch for ili210x touchscreen? http://linux-sunxi.org/Submitting_patches
<libv> 40 / (5 * 2.25) = 3.55
<libv> so we are actually doing slightly better than that
<libv> also, the pp can only push out one pixel per Hz, and there is only 1pp available
<Turl> libv: how much slower is it going to be on A13?
<libv> depends more on clocking and on the memory subsystem than anything else
<rastko> rz2k: ty
<Turl> their memory subsystem was cut in half I think
<libv> it's a mobile gpu, from back in the day when people were still selling predominantly 800x480 devices
<libv> even the s2 had some meek resolution
<Turl> libv: A13 has 16 bit SDRAM controller, A10 has 16/32 bit
<Turl> libv: galaxy s 3 has a mali 400
<libv> heh, s2 came with 4xpp, and only had to use it to fill 800x480
<libv> we have a quarter of the pixel sucking and pushing power
<libv> and a much worse memory controller no doubt
<Turl> SGS3 has 720p screen
<libv> so?
<Turl> A1X tablets are in the >720p <1080p range usually
<libv> still 4 PPs at 1 pixel per Hz
<Turl> so yeah we have way less :)
<libv> sgs3 is only clocked marginally higher
<Mehhh> A10 = 4x M4 @ 250mhz ?

<Turl> libv: so 1 pixel per Hz you say, that's like 320MPixel/s right?
<libv> Turl: yeah, but it will not be fully occupied
<libv> and there is a really good chance that it is simply bandwidth starved
<Turl> yeah
<Turl> libv: on an ideal world it'd be like 40% used only when painting a 1080p output
<libv> Turl: i am not sure how MPixels are measured here, because the shaders for q3a are several instructions long

<madmalkav> hi
<madmalkav> Allwinner a31 with quad a7 cores? what in the **** hell is an A7 arm core? how it compares with cortex a8, a9 and a15?
<mnemoc> madmalkav: the a7 is the little brother of the a15
<madmalkav> oh, cool
<madmalkav> haven't heard about that
<mnemoc> it's a low power companion
<mnemoc> same as the a5
<madmalkav> a15 for servers, a7 for mobile devices?
<mnemoc> no. they are supposed to live in the same chip
<mnemoc> switching from a15 to a7 when the load is low
<madmalkav> aaah, yeah, I read about that
<madmalkav> so, this is a cpu only made with those?
<madmalkav> weird
<mnemoc> the chinese found a cheap way of making "quad cores"
<mnemoc> good for marketing
<madmalkav> lkol
<Turl> mnemoc: the new allwinner is big.LITTLE? o.O
<mnemoc> no. it's only little
<Turl> o.o
<mnemoc> intented for cheap mobile... so it kind of makes sense
<mnemoc> it should be better than a dual a9
<Turl> power wise, or perf wise?
<mnemoc> both
<mnemoc> less power, better perf
<madmalkav> what's the status on linux support for the powervr gpu it uses?
<mnemoc> no idea
<Turl> it's all proprietary
<Turl> remember the intel poulsbo fiasco?
<Turl> well, that GPU was a PowerVR
<mnemoc> doesn't TI use SGX544 in their omap5 too?
<madmalkav> but there is a good propietary driver for linux ?
<mnemoc> madmalkav: gpu drivers are very platform specific. so, no.
<Turl> TI (usually?) uses PVR too, yeah
<Turl> madmalkav: there's "good" support for android usually
<madmalkav> fuck android
<madmalkav> so, we are as well as with the mali
<madmalkav> :/
tinti has joined #arm-netbook
<Turl> we have libv working on mali
<mnemoc> no. for mali there are linux drivers and a RE project with progress
<Turl> and the proprietary ones kinda work
<Turl> I think there's no powervr proprietary driver for X/non-android fb
<madmalkav> "kinda", that's the problem.
<Turl> well it's better than no support at all :)
<madmalkav> Beagleboard cannot run X? seems like it uses a powervr gpu
<Turl> you can run X without any GPU
<madmalkav> XD
<madmalkav> ok, I meant "Accelerated X"
<Turl> the mali X driver doesn't accelerate anything, correct me if I'm wrong
<Turl> I think it just lets you use GL on top of X
<Turl> rz2k: ^
<rz2k> yeah, it is standard dri2 pass thru
<rz2k> hooks for 2d acceleration are there, but they do nothing
<rz2k> we need g2d stuff be populated there
<Turl> apparently TI releases a SDK with blobs
<Turl> they seem to run qt without X? :p
<Turl> "deploy it and Qt to your board, and after shutting down X, run the example with
<Turl> the following arguments:"
<Turl> :P
<mnemoc> blobs that probably only work on TI hardware
<rz2k> qt can run on gles2
<rz2k> or XlibGL
<rz2k> techn_:
<techn_> rz2k:
<rz2k> regarding todays discussion in ML: r3p1 x11 libs seem to be doing better than r3p1 as they have needed depends and use libxcb (x server C bindings), might be that our dri2swapbuffers stuff fixed too
<rz2k> they still miss that symbol though
<rz2k> interesting thing is that I was able to launch linaros default XBMC with r3p1 x11 libs
<techn_> yeah.. It would be interesting to see benchmark results with r3p1 too :)
<rz2k> I was thinking about that too
<rz2k> maybe framebuffer ones get some fixes too
<techn_> what I remember.. there was some task scheduling fixes @ driver level
<techn_> but who knows.. could be even worse :p
<techn_> regarding sata performance.. working dma?
freakazoid0223 has quit [Read error: Connection reset by peer]
<techn_> and can it be applied to mali too?

<techn_> .42 version if no one has updated to .52
<techn_> check .gitmodules
<Mehhh> i meant malis
<Mehhh> sorry i should've said that
<techn_> r3p0
<Mehhh> Crap, but p1 is looking better according to rz?
<Mehhh> Well, for X11
<techn_> yes.. but we only have x11/framebuffer libs for r3p0
<techn_> oh.. sorry.. r3p1
<Mehhh> I suppose a mix-and-match wouldn't turn out so well ;)
<techn_> it can be done but.. it's complicated
<rz2k> someone with arm asm knowledge, please tell me what blx DRI2SwapBuffers; DRI2SwapBuffers: ADRL R12, 0xBD81C; LDR PC, [R12,#(DRI2SwapBuffers_ptr - 0xBD81C)]!; means exactly?
<techn_> you'll need kernel which has r3p1 mali module
<rz2k> blx is branch-link-execute afaik
<rz2k> 0xbd81c is _gles_bind_buffer+1
<Mehhh> Yeh, I guess i only had defaults on for that
<rz2k> questions is how to get rid of dri2swapbuffers import :/
<Mehhh> yuep, p0 from the cnx video page :\
vinifm has quit [Quit: Saindo]
<Turl> rz2k: if you put it on a pastebin I'll let you know
<ssvb> rz2k: this is likely a .plt section, which contains code thunks which do actual function calls via pointers
<ssvb> rz2k: are you sure nobody is using this function and you really don't need it?
<rz2k> we have dri2swapbuffers in xorg driver as malischeduleswap
<rz2k> and dri2proto gets the pointer there
<rz2k> and as I understood, it really works
<rz2k> so import in library is useless
<ssvb> what happens if you patch the binary and replace the "DRI2SwapBuffers" string with some other function name which is guaranteed to be available?
<Turl> can't you just make a dummy definition/alias then?
<ssvb> I'm not that very familiar with ELF format though, so don't know if it is going to work (maybe the function names must be sorted, etc.)
<ssvb> is /etc/ld.so.preload with some dummy library which has an empty stub for this function not an option?
<rz2k> I will find that out soon
<ssvb> rz2k: or maybe try something like "gcc -fPIC -shared -o new.so old.so file_with_dummy_DRI2SwapBuffers_function.c"
<mnemoc> this one has mali400
<mnemoc> "In addition, A20 is pin-compatiblewith its predecessor single-core A10"
<Mehhh> omgggggggggg
<Mehhh> reflow onto the A10 slot? ;0
<rz2k> lol
<rz2k> mnemoc: create topic @ cubieboard ML about this
<rz2k> maybe Tom will get more info
<hno> A20?
<mnemoc> allwinner published A31 and A20 today
<mnemoc> A20 is not in the menu, but linked from the "application" pages
<bfree> no sata in either that I see
<hno> bfree, sata is not mentioned in A10 briefs either.
<hno> Mail400 MP2.
<mnemoc> pin compatibility implies feature compatibility
<hno> And they link to Cubieboard and OLinuxIno
<mnemoc> also the hackberry :p
<Mehhh> LOL
<hno> mnemoc, kind of implies feature compatibility, but maybe not all features.
<Mehhh> it says it has
<Mehhh> 512MB L2 cache
<Mehhh> on the infographic
<mnemoc> wiki wiki
<hno> mentions SATA.
<hno> also says that A20 is quad-core, while A20 page says dual-core.
<hno> so still some typos here and there, likely to stay for some years.
<Mehhh> At least it doesn't say AMD Z130 GPU
<Turl> Mehhh: intel will go bankrupt ;)
<Mehhh> ;)
<Mehhh> Atom by Atom, they will crumble?
gimli has quit [Quit: Verlassend]
<Turl> hno: they also say "4Kx2K" and "2160P" on the others
<mnemoc> first moore's law, then moore's company
<hno> Turl, yes, and as we know what they mean with 2160P is 1080P 3D.
<Turl> lol, "visual bombox"
<hno> There also is an A12 it seems. http://www.allwinnertech.com/en/product/A12.html
<hno> Or... page says A10s.
* rz2k looks @ mali.so disasm and wonders why the hell mali400 library has functions and stuff for mali200 and mali300(wtf?)
<Mehhh> So, the A20 doubles the L1 per core, but keeps the L2 @ 256/ea?
<rz2k> also, I'm starting to suspect that libraries can be used for different SoCs, as register addresses and stuff are in kernel module.
* rz2k calls libv to the rescue
<hno> Mehhh, Unless it's shared L2.
<Mehhh> True
<mnemoc> Turl tested mali libs against a mali module with os-allocated memory and the libs crashed badly
<rz2k> that hwmem stuff from ux500/snowball?
<hno> Ok, 2160P vs 4Kx2K is explained. HD H.264 2160P video decoding / UHD H.264 4K ×2K @30fps video decoding
<mnemoc> our libs, our kernel. but mali's config.h changed to use OS_MEMORY instead of a hardcoded address
<Mehhh> Would I be looked down upon if I made an easier BSP / helper script for kernel / fs / tc / img creation?
<hno> Mehhh, it's too complicated today?
<mnemoc> Mehhh: why not helping to improve the current instead of making another?
<Mehhh> not really, but in terms of selecting
<Mehhh> i noticed the bsp didn't have the mk802 unless i moved the fex, etc
<hno> selecting what?
<Mehhh> modules without digging into cfg
<Mehhh> or being able to have it git into an exact structure and choose the malis for instance on the fly

<mnemoc> not that I know....
<Mehhh> If you have no rules, is that a rule? ::: brain explodes ::::
<mnemoc> there is no rule about not having rules
* hno settles for we have no rules defined.
<Mehhh> I think i found a bsp bug but i'll fix it. I don't think it's importing the mk802 fex on ./configure #
<Mehhh> I could be wrong and just sleepy :P
<mnemoc> that probably means sunxi-boards doesn't have an mk802.fex
<Mehhh> weird, mine does
<techn_> a20 is most interesting of those releases :p
<mnemoc> techn_: but hno is right. without sources, even if it's pin-compatible, it's useless
<techn_> if it's mostly a10/a13 compatible
<mnemoc> sun5i SDKs are a pile of bins
<mnemoc> nothing hints that will be improved in sun6i
<mnemoc> sometimes I wish to be lawyer to be able to sue companies at will :|
<Turl> mnemoc: well, on the other side they listed cubieboard, hackberry etc on their official site
alcides has quit [Quit: /(bb|[^b]{2})/ regular expression junkie + lover of literature...]
<mnemoc> Turl: yes, that was unexpected
<techn_> I think after success of this a10/a13 project, receiving sources wouldn't be that hard
<Mehhh> Ok so if i clone the boards git i do see the mk802 fex but not if i do the bsp
<Turl> the least they could do is hand tom the source if he does a cubieboard2
<techn_> .. I also think this project is currently at start.. even though hw starts to be aging
<mnemoc> Mehhh: that's a problem with git submodules, you marry a commit... not a branch :|
<Mehhh> So i guess i'll just upload it to the bsp
<mnemoc> Mehhh: cd sunxi-boards; git checkout master; git pull --rebase
<techn_> Mehhh: or make update :)
<Mehhh> ;)
<mnemoc> i'm not so sure `make update` does what's intended
* mnemoc hates git submodules
<techn_> it should checkout current head and rebases it
<Mehhh> you can't have them git from each other?
<hno> techn_, Olimex have never received usable SDK sources for A13.
<Mehhh> I do that with my linux configs all the time on git. Use a git to pull a submod to another git
<mnemoc> techn_: it most likely updates up to the commit it the submodule recort, not up to the head
<Mehhh> ahh
<Mehhh> I'm not trying to be a pain, just trying to streamline this
<techn_> mnemoc: yeah.. It could have some problems.. feel free to fix them ;)
<Mehhh> So are the fex files pulled or kept sep in the bsp?
<mnemoc> Mehhh: hold
<techn_> Mehhh: you'll need to add mk802 stuff to u-boot
<mnemoc> I just pushed a sub-module update
<Mehhh> awesome
<Mehhh> oh yeh crap, you're right techn_
<hno> Mehhh, not hardto do.

<techn_> mnemoc: I have opportunity to work @ home.. but just becouse of that I wont do it :p
<Mehhh> The mk802ii should be compatible with mk802, correct?
<Mehhh> uboot
<Mehhh> so I could just clone it and rename
<techn_> Mehhh: mele is most likely more compatible.. or how much memory your device has?
