<Seppoz> i could be wrong but a13 might not even have 2 usb
<Seppoz> check thre specs
<Seppoz> migth be a10s that only has 2
<Seppoz> a13 has 1 host so either they use a hbut
<Seppoz> or i dont know
<sleeply4cat> yes.
<Seppoz> any hub chip?
<sleeply4cat> I dunno. PCB is too dificult, and have a metallization; I can't use a lighter to trace internal connections (
<sleeply4cat> I can't recognize a few small chips, but, I think, they are too small for a hub.
<sleeply4cat> No, I think, there are no hubs on this board.
<Seppoz> ok

<Seppoz> sleeply4cat: what do you mean?
<Seppoz> sleeply4cat: to what usb is the module connected now?
<Seppoz> sleeply4cat: you have to read the cpu datasheet and see which pin in which GPXX
<sleeply4cat> Seppoz: I changed usb_controller_type = 1 to usb_controller_type = 0 in [usbc1].
<sleeply4cat> And now I have one more USB bus and wlan0 interface ^_^
<Seppoz> why the fuck yould you pick 1 in firts place
<Seppoz> ofcourse its 0
<sleeply4cat> bin2hex returned it =_=
<Seppoz> wait waht
<Seppoz> sec
<Seppoz> it must be 1
<Seppoz> sec
<Seppoz> let me check
<sleeply4cat> Yup.
<Seppoz> = 1
<Seppoz> usb_port_type = 1
<Seppoz> it should be 1
<Seppoz> oh you talking about port 0?
<sleeply4cat> I have done about 30 random changes in fex and about 30 tests ._.
<Seppoz> or port 1?
<sleeply4cat> port 1
<Seppoz> naaw port 1 i dont even think can be device
<Seppoz> are you sure thats what fixed it
<Seppoz> maybesomething else was wrong?
<sleeply4cat> Also, I changed usb_host_init_state to 1
<Seppoz> was it 0?
<sleeply4cat> +
<Seppoz> well there you go
<Seppoz> if its 0 it wont be init
<Seppoz> change type back to 1
<Seppoz> and set init to 1
<sleeply4cat> But without changing usb_controller_type it has no effect.
<Seppoz> did yu change port type or detect type?
<sleeply4cat> +
<sleeply4cat> hmm.
<sleeply4cat> Finally.
<Seppoz> does it detect any hub?
<sleeply4cat> I changed usb_controller_type and usb_controller_type.
<sleeply4cat> No.
<sleeply4cat> But now I have a wlan0 *_*
<sleeply4cat> And it seems working
<Seppoz> ok
<sleeply4cat> witchcraft >_<
<sleeply4cat> And..
<sleeply4cat> usb_drv_vbus_gpio = port:PG11<1><0><default><0>
<sleeply4cat> WHY???
<sleeply4cat> Why PG11?
<Seppoz> no idea, check your schematics
<sleeply4cat> Wifi is connected to other pin
<Seppoz> vbus is the USB vbus line
<sleeply4cat> so?
<Seppoz> its part of the port
<Seppoz> has nothing todo with wifi per se
<sleeply4cat> Well, wifi connected to pin 95 & 96.
<sleeply4cat> PG11 is pin 15
<sleeply4cat> >_<
<sleeply4cat> This makes no sense
<Seppoz> the cpu does not have something like pin 95
<Seppoz> what checmatics are you looking at
<Seppoz> *schematics
<sleeply4cat> зфпу 10
<sleeply4cat> *page
<Seppoz> oh you are a13 :/
<sleeply4cat> ...yes ._______.
<Seppoz> i keep forgetting
<Seppoz> others only have like AXX BXX and so on
<Seppoz> when you say wifi is connected to it
<Seppoz> what do you mean?
<sleeply4cat> I fully disassembled a tablet & traced connections.
<Seppoz> ok but what is connected to pin 95
<Seppoz> A and B?
<sleeply4cat> eww..
<Seppoz> let me show you what the vbus pin does
<Seppoz> USB1-DRV is the vbus pin
<sleeply4cat> Wifi module have 4 inputs. 3v3, gnd, d+, d-. D+ and di connected to 95& 96 pins.
<sleeply4cat> * d-
<Seppoz> well thats probably A & B
<sleeply4cat> okk
<sleeply4cat> So............
<sleeply4cat> Pin 15&16 used as a usb registers?..
<Seppoz> so
<Seppoz> vbus is like a pin that allows to take power from the usb port
<Seppoz> if your module is hardwired
<Seppoz> if doesnt matter what your vbus settings are
<sleeply4cat> *derp*
<sleeply4cat> It is too hard to my ponybrain.
<sleeply4cat> *for
<sleeply4cat> lol
<sleeply4cat> ewwwwwww..
<Seppoz> what do you mean?
<sleeply4cat> usb is magic.
<Seppoz> not that magic
<sleeply4cat> Tnx anyway %)
<Seppoz> you should still set the port type to host
<Seppoz> atleast to see what happens
<sleeply4cat> Ok, I'll test it.

<whitesn> excuse me, would anyone tell me the pro and cons booting from sdhc vs nand
<lukas2511> sdhc: exchangable, generally(?) more forgiving to power losses, may be faster (depending on card)
<lukas2511> nand: integrated, robust (no bad contacts or accidental removal of card)
<deasy> lukas2511, i think he wants to know about access times, this kind of thing
<whitesn> i mostly want to know about general performance (installation, cpu processing, ...)
Gerwin_J has quit [Quit: Gerwin_J]
<deasy> access time is the key ^^
<whitesn> what things do access time include?
<deasy> with a bit of bandwith
<deasy> width*
<lukas2511> oh okay, can't really help with exact data, but in my experience a class 10 microsd card was faster than nand (on olinuxino-a20-micro, may depend on nand chip)
<deasy> and also the drivers
<whitesn> so it won't be considerably slower, and actually might be faster than nand?
<whitesn> i accidentally bought a dual sdhc version of A20, and was considering to trade it with the NAND ones
<lukas2511> in my experience it was faster, using SanDisk Ultra microsd cards
<whitesn> it costs around 10 bucks, correct?
<whitesn> for 16G ones
<lukas2511> in germany it's ~11€ (~13.63$) for 16G
<whitesn> what size are you using?
<lukas2511> 16G
<whitesn> do you use it only for the OS or you use it for the storage as well? How much does typical OS usually take space?
<lukas2511> you could probably get a linux installation with xorg and everything in <2GB
<lukas2511> well, if you do it right probably <100MB, but yea
<lukas2511> and i use it as storage depending on the project
<deasy> i'll host pootle on my cubie via hdd2.5inch next year :)
<deasy> for the lfs project

<whitesn> alright, thanks for the info, really helping :D
<whitesn> i'll hang around here
<whitesn> i heard sdhc doesn't have wear leveling normally
<whitesn> so it's not really a good idea to use them as both storage and booting purposes?

<deasy> whitesn, it's right, no wear leveling
<deasy> that's why i have recommended you to buy one with at least 3years warranty
<whitesn> would it be safe to boot from sd card with no wear leveling? o_O
<deasy> ideally one "warranty for life"
<whitesn> extreme sdhc 8G costs around 11bucks
<whitesn> guess i'll just buy one with wear leveling
<deasy> i don't know if that exist
<deasy> for usbkey yes that exist
<whitesn> that exists
<whitesn> i just checked
<deasy> where ?
<deasy> link please
<deasy> whitesn, you meant than there is write it does wear leveling in chinese ?
<deasy> it's high end so i'll not be surprised it does
<whitesn> here
<whitesn> i wonder how would i write extreme pro in chinese search engine
<whitesn> ugh
<whitesn> 4bucks delivery fee
<deasy> i don't see wear on the page maybe it's put with others words
<deasy> it has ECC but ...
<deasy> ecc is not wear leveling
<deasy> and can be found even on cheap usbkey
<whitesn> oops
<whitesn> wrong link
<deasy> okay...
<deasy> the top of theirs products
<deasy> but i think the price is too expensive and better to switch with a ssd :p
<whitesn> 25bucks for sd
<whitesn> kek
<whitesn> is it a bad idea to boot it from 5400rpm HD?
<deasy> nop, why ?
<whitesn> would it be lagging?
<deasy> depends of what you do
<whitesn> how would that be compared to booting from nand / sd?
<deasy> i have not checked access time on sd...
<deasy> i can do it
<deasy> i just know hdd is around 17-18ms for a 5400rpm 2.5inch
<deasy> usbkey around 1ms for one good
<whitesn> i'm not sure how much that would affect the performance in general
<deasy> i test my sd sandisk ultra in some minutes
<deasy> but ...
<deasy> the allwinner access time can be different
<deasy> i don't know how is it fast directly connected to the soc

<whitesn> looking for sd speed bottleneck on cubie..
<deasy> the usual bottleneck in use is IO or access times ^^
<deasy> 0.97ms
<deasy> it's faster than my faster usbkey
<whitesn> cost 13-14$ though
chkktri has joined #linux-sunxi

<deasy> there is no fake product on these TW websites ?
<whitesn> usually no on the tmall ones
<whitesn> sometimes on taobao, but you can inspect that through comments
<whitesn> not sure if they really do have wear leveling
<whitesn> with the price
