<hno> cubieboard have 2 USB HOST + 1 OTG.
<rzk> hey hno, is there any chance to boot something on A13 from mmc right now using uboot-allwinner sun5i branch?
<hno> rzk, Well, u-boot boots fine. Not sure if it's capable of also booting a kernel..
<rzk> also, if my device doesnt have reset button, am I stuck with "#error reset the board#" on cold boot?
<rzk> I remember sometime ago you managed to reset the board remotely for some reason
<hno> rzk, cold boot should work fins.
<hno> s/fins/fine/
<ibot> hno meant: rzk, cold boot should work fine.
<rzk> on my A10 tablet it never did with u-boot from mmc.
<hno> did you try another SD card? It's apparently a bit picky on the type of card used.
<hno> probably some little detail missing in the u-boot mmc setup.
<hno> (un)fortunately cold boot works with all cards I have.
<rzk> yep, but nevermind, that A10 tablet is dead anyway, bad BGA job by manufacturer and my laziness to reflow it right way.
<hno> my remote reset is just that I managed to wire my JTAG adapter on the A13 board so that I can reset the board, and also figured out how to tristate the other lines so it does not disturb SD booting.
<rzk> cool, what jtag do you use?
<rzk> generic ft2232?
<hno> An olimex one, FT2232 based.
<hno> ARM-USB-TINY-H
<rzk> at JTAG article at wiki there is a adapter board with some pull-up/downs, are they mandatory?
<rzk> or that is inline 10-20ohms?
<hno> Works fine without them for me. But there is both inline resistors and pull downs (or was it up, don't remember) on the A13 board.
<hno> I have both SD-card and JTAG connected in parallell.
<rzk> now its time to find out what is what in this heap of testpoints http://linux-sunxi.org/File:Q88-pcb2.jpeg
<hno> Looks like mostly touch panel stuff.
<hno> but one of the big one is labelled RST, might be system reset.
<hno> Ah, the rest there is the SD UART pins.
<hno> but if you plan on SD booting then finding UART1 pins (PG3/PG3) helps a lot.
<hno> PG3/PG4
<rzk> thanks hno
SammerZ has quit [Ping timeout: 244 seconds]
<hno> rzk, UART1 is most likely the two pads between the SD slöt and A13.

revident has joined #arm-netbook
<RaYmAn> hacky as hell, but you could add code to setup jtag & loop forever at relevant points..E.g. in u-boot just before it jumps to kernel?
<RaYmAn> assuming you are talking sd-boot anyways
popolon has joined #arm-netbook
<hno> RaYmAn, easier to just reconfigure the port to JTAG before invoking bootm.
<hno> everything is already loaded from SD at that point.

<hno> Marex, something is fishy. u.boot runs fine but system crashes when trying to boot Linux kernel, with a known good kernel.
<hno> seems to crash before jumping to the kernel, but not sure yet.
pwhalen has joined #arm-netbook
<Marex> hno: do you see "uncompressing linux"
<Marex> hno: that's the decompressor, so it's not a uboot problem ...
<Marex> hno: check if proper machine ID atag is passed
<hno> I don't. And the kernel have it's machid hardwired. (Allwinner legacy crap, will get rid of that in due time)
revident has quit [Quit: Salty....]
<Marex> hno: does the kernel uImage pass crc check ?
<hno> Yes, and u-boot do jump into it fine.
ibrah has quit [Ping timeout: 245 seconds]
<hno> Ah, that... the kernel is built for uart0 and I am using uart1 now.
<RaYmAn> minor detail :P
<RaYmAn> hehe
<hno> thought uart1 was at least enabled in script.bin but not even that.
* RaYmAn hopes for his a13-olinuxino to arrive tomorrow
<hno> that would be nice indeed.
<RaYmAn> It's a pity those PG JTAG pins aren't brought out anywhee - I *think* it should work
<hno> Which JTAG pins?
<hno> On the A13? not all PG pins needed for JTAG exists on A13.
<RaYmAn> oh
<hno> Maybe the second JTAG port exists on other pins, but I don't think so. A13 is not something you are supposed to JTAG.
<RaYmAn> minor issue :P
<Marex> ugh
<Marex> these sausage chips are really ... messed up :S

<Marex> hno: in Linux you say ?
<hno> yes
<Marex> hno: it's a binary of linux kernel ?
<Marex> hno: one that booted somewhere else? or did you rebuild it ?
<hno> It's a binary that RaYmAn built earlier. And known to get past that stage earlier on my board when booted without u-boot.
<Marex> hno: it's an uImage or zImage ?
<hno> uncompressed uImage of an uncompressed linux image.
<Marex> hno: why uncompressed ?
<hno> why not?
<Marex> hno: that leads me to a question -- are you loading it to loadaddr-y ?
<Marex> hno: because you bypass the decompressor that way, which places the kernel at the right address (if not done so )
<hno> yes, it is loaded at the correct address.

<hno> Hm.. trying to get into the printk call and openocd gives me a fist..
<L84Supper> interesting http://www.cnbeta.com/articles/196089.htm the next gen allwinner might be quad core Cortex-A7
<popolon> buy now still doesn't works :/
<popolon> s/piece/coin/
<popolon> L84Supper, and some other will mix several cortex A15 cores with 1 cortex A7 core, for its very low power consumption
<popolon> called Big.LITTLE architecture
<L84Supper> popolon, yeah, I've been a hardware engineer for >30 years. I was just commenting on what allwinner was up to
<rm> the pins on the gpio pads seem to be short (?)
<popolon> the rumor about cortex a7 is from begining of july, no confirmation since, isn't it ?
<L84Supper> popolon, how is the cubieboard working?
<rm> like half-height pins
<popolon> I would like to test it :)
<L84Supper> if we had an ARM soc with open specs to allow for full open Linux support how many people would really care?
<L84Supper> win8 is moving to closed hardware from M$, everything else is Android or iOS
<L84Supper> there would seem to be quite a bit of opportunity for linux and open PC hardware to take off, but nobody seems to be interested
<L84Supper> or relatively few concerned
<popolon> lot of computer are sold without OS in computer industry, mostly industrial servers
<Turl> dell sells ubuntu PCs
<popolon> if there is an hardware thumbEE accelerated version of php or ruby, this could be an opportunity for arm
<L84Supper> I wonder if the DIY mainboards/cpu's/etc will jump 500% in price in the next few years duo to lack of mass production
<popolon> Turl, they sold before, but I think Microsoft kicked them
<Turl> they still do
<Turl> go look for ubuntu on dell.com
<popolon> nice :)
<L84Supper> M$ appears to be pushing PC hardware vendors out of business
<popolon> well when I search for ubuntu and click for the first choice on dell.com
<L84Supper> how many people will care about Linux on an open ARM tablet or PC?
<popolon> => no products available for this fitler
<popolon> there is a link to a wiki about moblin
<hno> Oh, new cubieboard pictures. Something is happening.
<popolon> hno :) yes
<hno> and corrected description on home page.
<L84Supper> the cubieboard is not shipping yet?
<popolon> L84Supper, fablab people and hardware geek ?
<Turl> hno: what's that audio looking jack on the ethernet side?

<L84Supper> R-pi is a social experiment to see how many people support a closed board that is labeled as open
<Turl> L84Supper: rpi is "open" by the majority standard
<popolon> oh, because of nda of broadcom ?
<L84Supper> Turl: so closed is the new open, got it
<hno> Turl, one is headphones, not sure on the other but I would guess mic or video.
<Turl> L84Supper: it can run anything you wish, it's got no digital locks, and does gpio
<popolon> and need to buy a licence for hw accelerated mpeg2 even in countries without software patents
<L84Supper> Turl: can I run my own firmware on it?
<hno> L84Supper, on the cubieboard? Yes.
<Turl> L84Supper: firmware as software? sure
<hno> on the rpi? kind of...
<L84Supper> hno: sorry, I meant the pi
<L84Supper> maybe they opened the gpu bootloader since I looked last
<Turl> j1nx_: btw, how's xbmc development nowadays? did you guys get something decent to work with from allwinner?
<hno> L84Supper, not last tiem I looked. And seriously doubt it will ever happen as every breath related to the GPU is under NDA.
<j1nx_> Turl: Gimli got some other files, a little bit better, but not much
<Turl> L84Supper: people nowadays call it open when !locked
<L84Supper> hno: ok, so it's still has the secret blobs
<j1nx_> the ball is again at their coart (6 days)
<Turl> well, nice to see them moving, even if a little
<j1nx_> I stepped away for the moment because 1) I can't do anything without the decoding support in place
<j1nx_> 2) I am still a bit "disappointed" with them
<hno> What is the problem that allwinner need to solve?
<L84Supper> very clever! Just label closed as open. Soon well will also have cold heat, free prisons and dry water.

<Turl> L84Supper: the thing is, "openness" is not a white/black thing
<hno> compared to an average android the rpi is open.
<Turl> ^ that
<popolon> I'm for dry water, should be lighter in bags ;)
<Turl> popolon: I can sell you a dry water generator, it's called vacuum :D
<popolon> :)
<j1nx_> pffff. all this stuff reminds me of my biggest mistake during school
<j1nx_> They let me search for "aromatic free bezene"
<j1nx_> And believe me as a chemist you should not make that mistake

<rm> I'd ask are there any GPIO at all
<rm> > "96 extend pin including i2c, spi, lcd, sensors, .."
<rm> doesn't mention GPIO
<hno> pinouts have not been posted yet I think.
<L84Supper> maybe not
<Turl> rm: all those crapton of pins are gpios multiplexed with all that I believe
<L84Supper> yeah, lots of muxing
<hno> yes, nearly all A10 I/O pins are GPIO capable.
<L84Supper> i wonder how many GPIO are actually fast
<hno> fast as in?
<L84Supper> not just for LED's or switch inputs with debounce or similar but for <uS setup times
<L84Supper> nS setup and hold times
<hno> It's CPU controlled, which puts some limits on time ranges.
<L84Supper> I've never seen any specs on the IRQ arbitration in the A10 or how the internal buses are even arranged
<rzk> lol, all available A13 livesuit images that I've found have wrong image header, saying different file size than its really are
<Turl> hmm
<L84Supper> no AC timing specs
<Turl> hipboi claiming 1.5Ghz
<rzk> because of that, all unpackers for livesuit images fail miserably, allocating not enough memory for the file.
