* rellla 's quote of the day: "Your help will be greatly appreciable" ;)
<mripard> wens: you're doing what?
<wens> mripard: the pinctrl-sunxi library accesses registers based on the pin number, without accounting for .pin_base
<wens> as a result, for the r_pio device, none of the pinmux settings work (unless they were set by u-boot)
<wens> I'm taking a look at GPIO numbering as well
punith has joined #linux-sunxi
<mripard> you don't need to take pin_base into account to access the registers
<punith> in my custom A20 board i tried to flash android from phonix suite but getting fallowing error
<punith> [PHY_DBG] can't get right otp value from nand otp blocks, then use otp command
<mripard> wens: it's only for the GPIO numbering
<punith> what is mena by otp value in nand
<mripard> wens: oh, no, nevermind
<mripard> do you have a kernel booting on the A23 ?
<wens> yes I do
<mripard> cool
<mripard> where are your patches then ? :)
<wens> I guess I could submit what's working now, they fix some of the glitches I spotted during the -rc period
<wens> though my tree is based on sunxi-devel, and I'm not sure what patches have been merged
<mripard> all the important ones I guess
<mripard> we have MMC and USB in mainline now
philippe_fouquet has joined #linux-sunxi
<wens> MMC hangs on my tablet, and there aren't USB devices on my tablet
jemk has joined #linux-sunxi
<wens> btw, did anyone get SATA to work on the A31?
<mripard> there's no SATA on the A31
<mripard> so... no :)
<bbrezillon> wens: Oops. Indeed, I forgot to substract pin_base to pin when passing to to sunxi_pinctrl macro (sunxi_xx_reg and sunxi_xx_offset)
<wens> hmm, hans has the Mele A1000G (photo has SATA connectors)? maybe I'll ask him
avsm has joined #linux-sunxi
<wens> bbrezillon: maybe we could subtract .pin_base when we register the individual pins?
<bbrezillon> wens: you already prepared a patch to fix that (the pin_base issue) ?
<wens> and for GPIO as well
<mripard> wens: it's a USB to SATA bridge
<wens> mripard: I see
<wens> funny the PLL6 document for A23 lists a SATA PHY gate
<wens> left over I suppose then
<wens> bbrezillon: the quick fix would be to subtract it before passing it to sunxi_*_reg, but I think there's quite a few places
<wens> the other solution, which IMO is better, is to subtract pin_base when registering them, and add back pin_base when searching though sunxi_desc_pin, so they match
<wens> I'm just not sure about how the core handles everything
<bbrezillon> wens: I'll let mripard decide ;)
<oliv3r> bbrezillon: hey! looks like your still busy with sunxi :)
<oliv3r> bbrezillon: what's the nand status? do we have dma enabled nand driver?
<bbrezillon> oliv3r: nope
<mripard> wens: I think I prefer to fix the macros, it's less error-prone I guess
<oliv3r> wens: could be a copy/paste mistake or not brought out in the final a23 chip, you should know how aw does their docs by now!
<bbrezillon> oliv3r: I'm still trying to get NAND basic stuff mainlined
<oliv3r> ah good good
<oliv3r> how's that going? ( haven't ckept up at all
<oliv3r> and if nand is mainlined I might switch to a mainline kernel for our project soon-ish
<oliv3r> though DMA maight be crucial :(
<mripard> then use A31 :)
<oliv3r> mripard: a31 has nand + dma?
<oliv3r> but nah, a31 is WAY to expensive and no devboards
<oliv3r> we're going to use the Lime :)
<mripard> there's devboards.
<oliv3r> for 30 euro's? :p
<bbrezillon> oliv3r: ATM we're discussing the NAND timing description, and I have to fix some bugs pointed out by Ezequiel
<mnemoc> is A31 Hummingbird is still not shipping
<oliv3r> bbrezillon: awesome :)
<mripard> oliv3r: development kit are usually in the 2-3000 euros pricetag you know :)
<oliv3r> yeah but the hummingbird is double the price of a Lime
<mripard> and yes, there's the hummingbird
<mnemoc> just 50E :p
<oliv3r> then i didn't mean devboard; but a 'raspberry pi like board' :p
<oliv3r> something you pick up and stick into a product :)
<mnemoc> (ok 52 + 15)
avsm has quit [Quit: Leaving.]
<oliv3r> so its either the Lime, or not allwinner based board :)

blsd has joined #linux-sunxi
<oliv3r> though currently, we'd only need USB, Nand and SPI support mostly
<libv> rellla: haha
<libv> Lumocolor: i and a few others here do have a lime, but i have no uext modules, and i haven't spent much time with it (i also lack the smaller pitch cable still)
<oliv3r> hey libv! how's things with you?
<Lumocolor> libv: ok :). I was just wondering how bulky it would be with the 4.3inch lcd module? in the context of a DIY little, as compact as possible handheld pocket computer
<mripard> oliv3r: I was just teasing you, don't worry :)
<Lumocolor> I've learnt that a a20 LIME is due to be released, so I'm waiting for the new version
shineworld has joined #linux-sunxi
Andy-D has joined #linux-sunxi
<oliv3r> mripard: bah! you tease!
<oliv3r> that sounds dirty ;)
<oliv3r> mripard: but in all seriousness, does A31 have DMA + Nand? I'd expect DMA only?
<oliv3r> Lumocolor: a20 lime is expected to be much pricier though
<mripard> it has DMA
<mripard> and we were talking about the NAND itself yesterday with bbrezillon, and the controller looks similar
<oliv3r> mripard: you commited the SPI and DMA stuff to a10/a20 too?
<oliv3r> not all unlikly and very cool
<Lumocolor> oliv3r: how much more~ ?
<oliv3r> i'll buy you all cake if nan enabled DMA is available in august :)
<oliv3r> Lumocolor: not sure, but it won't be as cheap as lime v1 for sure
<mripard> oliv3r: only SPI
<mripard> for DMA, see with Turl_
<oliv3r> Turl_: ^^
<oliv3r> i guess we can do the initial release with 3.4 and switch to mainline kernel later :)
<oliv3r> mrnuke: didn't you work on flashrom stuff using SPI? or was it avrdude stuff using SPI?
<oliv3r> oh btw, it looks like I might be at FOSDEM 2015 if all pans out, manning a booth :D
<atsampson> did anyone have a PWM driver for mainline? (I vaguely remember oliv3r mentioning it on the list in the past...)

<oliv3r> mripard: wouldn't do what? release a software upgrade that replaces the entire OS, rootfs + kernel with something based on mainline?
<oliv3r> or not use the mainline kernel at all yet, as it's not reliable enough?
Black_Horseman has quit [Ping timeout: 240 seconds]
<Lumocolor> oliv3r: well thanks for the heads up, I guess it will be £20-£30 more
shineworld has quit [Remote host closed the connection]
<mripard> oliv3r: change from 3.4 to mainline during the life of the product
<Lumocolor> makes it the same as the cubieboard but it will have battery circuitry built in and I'll have to wire up audio sockets + some components like in the a20-micro manual

<n0wl> hello all
<n0wl> I have here a android A20 TV Box simila to the qt840a
<n0wl> but is not identical and the manufacturer is a different one
<n0wl> anyway, it has eth0 connectec through mii over IC+ IP101GA
<n0wl> cannot get it working ...
<mripard> Montjoie: usually, it's just help
Lumocolor has joined #linux-sunxi
<n0wl> found some suggestions like the ones from Amit Kucheria but not patches for the gmac driver
<n0wl> does anyone here knows what exactly need to be patched in the gmac driver?
<n0wl> I changed already in the gmac_plat.c the RGMII to MII but still no link
<n0wl> kernel is 3.4.90-dirty
<n0wl> would be great if somebody could help
<amitk> n0wl: do you use enable SUNXI_GMAC in uboot?
<amitk> n0wl: you'll probably also need to setup the PH21 GPIO correctly
<n0wl> SUNXI_GMAC is enabled - with the option of using the script
<amitk> n0wl: in uboot and in the kernel?
<n0wl> if I enable the PH21 than I cannot see any eth0 at all
<n0wl> with PH23 at least got some errors
<n0wl> just kernel
<amitk> n0wl: you need to enable it in uboot as well, I have a line like this in boards.cfg: +Active arm armv7 sunxi - sunxi qt840a sun7i:QT840A,SPL,SUNXI_GMAC,STATUSLED=244,FAST_MBUS -
<amitk> n0wl: replace QT840A with cubieboard or whatever uboot target you are using
<n0wl> the name of this device is SDK-758 from Sunchip tech , a shenzhen based company
<n0wl> from ports and layout look very similar to qt840a
<amitk> n0wl: you should probably start documenting it on the wiki to begin with
<n0wl> just arrived yesterday :-)

<n0wl> amitk: still working on it.
<n0wl> as soon I got it working I will document it to the wiki
ganbold__ has joined #linux-sunxi
<amitk> n0wl: it claims to have a 3.0.8 kernel and a realtek wifi chip. So definitely not the same box
<amitk> n0wl: your best bet is to extract the original fex file, if possible the kernel config
<n0wl> kernel is 3.4.39 android 4.2
<amitk> ok
<n0wl> the realtek is a usb module soldered on the backside of teh pcb
<n0wl> all runing in flash
<amitk> nice :)
<n0wl> but if a microSD is inserted automatically boots from sd
<amitk> n0wl: the point was that there are enough differences that even the GPIOs used to power the PHY might be different, best to get the original fex
<n0wl> amitk: what have you changed in the gmac driver?
<amitk> different from the qt840a, that is
<n0wl> cannot find pictures of the qt840a pcb
<n0wl> so I cannot tell exactly
<amitk> n0wl: I've also separated the platform driver registration from the platform device registration but that is not a functional change
<n0wl> but as I have some experience with chinese manufacturers
<n0wl> so for quite sure it is a reference design used with little changes
<n0wl> when I saw it a had a deja-vu
<n0wl> amitk: thx I will try

<bbrezillon> wens: okay, this one should be correct http://code.bulix.org/6ink8b-86269
<bbrezillon> :-)
<wens> looks good :)
<wens> mripard: nice, sunxi_pctl_desc looked fishy to me, but didn't look into it yet
<mripard> wens: yeah, it was working fine until we had several pinctrl devices at once
<wens> bbrezillon: do you want to send? I also have a patch which I think fixes disabling pull-ups, to match the DT docs
<bbrezillon> wens: be my guest :)
<bbrezillon> wens: you're the one who found the bug after all ;)
<mripard> wens: ?
<mripard> wens: what do you mean ?
<wens> mripard: in the DT, if we pass 0 for the pull-up, the driver ignores it, instead of writing 0 to the register
<wens> any pull-ups/downs done by the bootloader are left intact
<mripard> yeah, it's actually something I wanted
<wens> but the bindings say a value of 0 should disable the resistors
<wens> I am afraid if we actually fix it, we'd break some DTs
<mripard> yep, there's that, but I guess this would be for the best
<mripard> but it's also mostly because all that bootloader side in completely undocumented
libcg_ has quit [Ping timeout: 252 seconds]
<mripard> so, we don't really know what's going on
<mripard> leaving the pull-ups configuration is convenient
<wens> I guess we should fix the binding documents then?

<Turl> CaptHindsight: devboards are easy, but tablets I really don't know :/

<CaptHindsight> Turl: I need SPI to connect to an FPGA
Quarx has quit []
<CaptHindsight> I can make one, but I'm just searching for a hackable tablet
<Turl> CaptHindsight: you can look at the user manual and see where the pins can be muxed to
<Turl> maybe if there's i2c on the nand pins you can remove nand and reuse the pins or something
<CaptHindsight> yes, as long as the pcb traces have been brought out from the balls
<CaptHindsight> I can de/solder anything

<Turl> CaptHindsight: having a quick look, the PC0/1/2 pins can be muxed to SPI0_MOSI/MISO/CLK
<Turl> those are 3 pins used for nand according to one of the fex I opened
<CaptHindsight> was easy using the cubie2
<Turl> yeah, devboards just have it on headers :)
<CaptHindsight> we got preempt_rt and xenomai working using the debian image for the A20 but the tool chain was full of magic
<CaptHindsight> who has the most magic free linux system for the A20 at the moment?
<Turl> you'll need to define magic :)
<CaptHindsight> no code sorcery for one
<CaptHindsight> no ubuntu
<Turl> the most common cross compiling toolchains are linaro's, code sorcery's and whatever on your distro package manager
<Turl> we have a page on toolchains btw https://linux-sunxi.org/Toolchain

<CaptHindsight> we started building from scratch using Gentoo
<CaptHindsight> if we build this we have to support it

<Turl> their buy button doesn't even work anyway :p
<CaptHindsight> nice
<CaptHindsight> not sure what that form factor gets you
<Turl> rpi (pseudo?)compatibility
<CaptHindsight> the A20 in duino format at least gets you shields/capes/sarapes/expansion IO boards
<Turl> maybe you can reuse a case or two
<CaptHindsight> same pinouts and form fact as the RPi
<Turl> and their header is supposedly the same, so maybe some hw addon as well
<CaptHindsight> fact/factor
<CaptHindsight> we just want A20 with FPGA for IO, HDMI and USB
<Turl> CaptHindsight: something like Parallela but with A20? :p
<CaptHindsight> we have an FPGA board for the cubie2
<CaptHindsight> yeah
<CaptHindsight> we just need to finish xenomai or port RTAI
<CaptHindsight> and have a reproduceable clean tool chain
<atsampson> I couldn't understand why the ethernet port's in a different place on the BananaPi -- that means none of the cases will fit, surely?
<CaptHindsight> oh so it's not even the same locations for ports
<CaptHindsight> whats the point then?
<atsampson> I'd definitely be interested in a sunxi board that was actually RPi compatible -- particularly if it could use the RPi camera module...

<atsampson> hmm
<CaptHindsight> in the same pic side by side http://raspi.tv/wp-content/uploads/2014/04/DSC_0621_1500.jpg
<atsampson> so are there two revisions of it?
<CaptHindsight> dunno?
<atsampson> I'd not seen the version with the vertical SATA connector before
<Turl> the rpi is smaller
<Turl> assuming they're really side by side and it's not a two photo copy paste
<CaptHindsight> the SATA connectors come in straight and 90's that fit the same footprint
<atsampson> yeah, but there are lots of other differences between Front_of_Banana_Pi.JPG and bananapifront.jpg
<atsampson> the latter looks a lot closer to the RPi layout...
<atsampson> ... but the former's what's shown on aliexpress, etc.

<CaptHindsight> $10-20 FPGA with A20 is fine
<CaptHindsight> 2 cores, decent GPU, HDMI, SATA and USB and plenty of IO's for control with the FPGA
<CaptHindsight> + Ethernet
<CaptHindsight> the Parallella just lacks a GPU to support HD HMI/Displays

<RzR> hi can you confirm that framebuffer is only available in 3.4 branch ? or are there later WIP ?
Andy-D has quit [Ping timeout: 265 seconds]
<libv> CaptHindsight: some tablets have motherboard pictures
<libv> RzR: yes.
<libv> RzR: you didn't read the wiki apparently.
<libv> RzR: otherwise you would've known about mainline.
<RzR> yes I know
<RzR> I read it
<libv> yet you assumed that it's contents was invalid or outdated or ...
<libv> just didn't apply to your world?
<RzR> just wanted to be confirmed
<RzR> ie
<RzR> I can edit this page
<RzR> and add this only applies to 3.4 branch
<libv> CaptHindsight: those with loads of pads exposed might have something that can be muxxed to spi
<RzR> anyway let me thank you for your efforts
<libv> RzR: the whole website pretty much applies only for 3.4
<libv> RzR: those working on 3.14 are too good for wiki work.
<RzR> I bookmarked your fosdem talk i missed
<libv> the only thing they do update, very regularly, is their mainlining page
<libv> so you would've had all the information you needed from there
<libv> if you had cared to trawl through it

<calhemp> hi guys, thanks for your effort
<calhemp> i've a cubieboard a20 and a mele a2000, both with an attached hdd inside a dvd ;) with a 3.4.75 kernel working well for my home needs, I can read hddtemp and also have a temp sensor
<calhemp> but is posible to get more temp data for this boards? like cpu temp or another?
<rz2k> axp2xx had a temp sensor and touchscreen driver has one

<calhemp> aha, thanks rz2k, I will have to read more about this, I'm a newbee but if I find something about this, i'd like to test this options.
<rz2k> come at day time in europe, there's barely anyone here at deep night
<rz2k> also you can ask on our mailing list
<calhemp> i read in linux sunxi mailing list about effort in write driver for apx2xx, is this enabled in the default git branch?
<rz2k> if I remember correctly, yes.
<calhemp> thanks rz2k, I will read a little more and ask another day how to test or if there is a kernel available for try and report my results. thanks good night
