Hi there
<Vanfanel>
are there instructions to flash new Android img files to NAND from withing the Cubieboard running Debian Linux itself?
<Vanfanel>
It's VERY difficult for me to enter FEL mode because I have to remove the board from it's case, and that's not easy

Is possible install any Linux system in Cubieboard ?
<ttmrichter>
Mr_Electronico: Well, you can't install a Linux system compiled for x86 obviously.
<Mr_Electronico>
Ok..then how I can install ?
<Mr_Electronico>
How I can translate any Linux system to Cubieboard
Mr_Electronico has quit [Quit: Leaving]
<ttmrichter>
You get a Linux system compiled for the A10/20 (as appropriate) or you build one yourself.
<ttmrichter>
You're kind of asking here "how can I make a chocolate chip cookie out of broccoli".
<ttmrichter>
It's ... just not a sensible question.

i can't compile firefox or opera for gentoo on cb2. i guess some code has to be arm-specific. which browser can i use with cb2 that can cope with today's technology?

what is the error?

<emx>

<Wizzup>
You'll have the error that fast?
<emx>
Wizzup, which resolution do you use in X?
<Wizzup>
I am not actively using my cb2 atm
<Wizzup>
Why do you ask
<Wizzup>
Typically 1080p
<emx>
Wizzup, yes. it is the binary btw.
<Wizzup>
Oh..
<Wizzup>
emx: That will not work
<emx>
Wizzup, i use fbturbo as gfx driver at it only goes up to 720p
<Wizzup>
Do you have pulseaudio enabled?
<Wizzup>
emx: I doubt that somehow @ gbturbo :)
<emx>
Wizzup, when i try to emerge firefox (not -bin) i get another error message in libvpx.
<Wizzup>
which error
<Wizzup>
I can help with that
<emx>
Wizzup, i think no. why?
<Wizzup>
probably just need libvpx stable
<Wizzup>
emx: I may have a binary build somewhere
<Wizzup>
no guarantees
<emx>
Wizzup, let's try the hard way first :)
<Wizzup>
emx: I recall you need newer - unstable - libvps
<Wizzup>
vps
<Wizzup>
has something to do with new glibc and upstream advice is to get new version
<Vanfanel>
ssvb: AreaScout and I have two different MALI(GLES/EGL) and LIMA backends for RetroArch, but we're having problems with vsync. The ioctl I'm using, FBIO_WAITFORVSYNC, is causing the emulation of all systems to be very slow. Isn't there a way to simply activate EGL vsync so there's no need for this ioctl before calling eglSwapBuffers() ???
<Fangorn>
Hello
<emx>
Wizzup, X11 is a dead link, right?
<Fangorn>
Any try connect dac over spi or i2s?
<Wizzup>
emx: it appears so, ask swabbles
<Wizzup>
swabbles: PING
<ssvb>
Vanfanel: FBIO_WAITFORVSYNC naturally limits the framerate to 60 frames per second, and it needs to be called after (not before) eglSwapBuffers to avoid tearing
<Fangorn>
Nobody?
* Wizzup
has not yet
<Wizzup>
swabbles: Have you considered making a cubieboard overlay?
<Vanfanel>
ssvb: thanks for the clearing!! I run to test it NOW!! :D
<Wizzup>
swabbles: Maybe we should
<Fangorn>
I see alsa for soc don't support allwinner
<Fangorn>
But i found ready for use dac extension for cubie, but for 300-400$
<Fangorn>
Anyone has it?
<emx>
Wizzup, did you crosscompile your gentoo?
<Wizzup>
No
<Wizzup>
I did use binpkg for it, because my ODROID has a binpkg
* Fangorn
also have question... how you use your cubie?
<Wizzup>
Fangorn: cubieboard audio should just work
<Wizzup>
afaik
<emx>
Wizzup, k. which one do you like better for playing fullHD movies?
<Wizzup>
emx: Cannot comment. I have seen swabbles playing fullhd movies on his cubie.

Odroid, I mostly use it as build server and desktop
<Wizzup>
never got hw decoding ti work
<emx>
where is that swabbles guy?

in here.
<Wizzup>
Never put a lot of effort in trying to get odroid hw decoding to work though
<Wizzup>
He sleeps at the weirdest times though
<Wizzup>
;-)
<emx>
hehe
<Fangorn>
Wizzup: I intresting to use more quallity dac
<emx>
i started the emerge with the unstable libvpx. unfortunately python has to be recomplied so it will take some time.
<Wizzup>
Fangorn: maybe a usb audio card?
<Wizzup>
emx: heh, firefox will take hours
<Wizzup>
make sure you have some swap on a HDD (not microsd)
<Wizzup>
and please dont compile on microsd. they break
<Wizzup>
:)

Wizzup, good point. seems like i need to reswap to my ssd.

yes, probably
<Wizzup>
emx: or just mount /var/tmp/portage on it
<Wizzup>
Fangorn: okay,then I do not know
<Fangorn>
Gentoo at cubie work? How many time spend compiling all at cubie?
<Wizzup>
gentoo works on _ALL_ the things
<Fangorn>
Or all use crosscompilling?
<Wizzup>
And darn well, too :)
<Wizzup>
Fangorn: As stated, I compiled a lot on my quad core arm, but compiling on cubie works fine too
<Fangorn>
I like gentoo )
<Wizzup>
Just don't use microsd :))

Why not at big x86 pc?

Fangorn, currently i'm sitting at an octacore laptop and all i do is chatting in irc and browsing.
<EdBr>
I use wifi but it doesn't work
<emx>
EdBr, hi. thanks for telling :o)
<Wizzup>
Fangorn: cross compiling is not always easy
<Wizzup>
typically you end up with qemu-user and stuff
<Wizzup>
A bit of a pain
<Wizzup>
Some packages do not like being cross compiled
<Wizzup>
I found either using a different ARM machine (same arch) or just on the device itself is easier
<ssvb>
Vanfanel: as for vsync, this does not make much sense
<EdBr>
U use this image
<Wizzup>
emx: I am actually using gentoo on cubie2 for work, so I'll definitely get back to you
<Wizzup>
probaby with guides, later
<emx>
Wizzup, k. i just realised that the last commit to "gentoo-on-arm" removed X11.md.
<Fangorn>
EdBr - you see my messages?... )
<EdBr>
emx: I use Nand Image
<Wizzup>
emx: heh
<emx>
Wizzup, did you use the overlay, btw?
<Vanfanel>
ssvb: thanks
<EdBr>
Fangorn: when I conected I see "server not found"
<emx>
EdBr, then tell us what lsusb lists.
<ssvb>
Vanfanel: FBIO_WAITFORVSYNC waits until the previously scheduled FBIOPAN (called from eglSwapBuffers) takes effect
uizex1 has joined #cubieboard
<emx>
EdBr, you can use pastebin.com or pastie.org to post your output.
<Fangorn>
emx - they say that already connected to wifi. Think all right with hardware
<Vanfanel>
ssvb: the problem here is that, sadly, I'm getting a way slower gles performance from the Cubieboard2 than I get from the Raspberry Pi for RetroArch using GLES, IF I use that ioctl to wait for vsync. So, isn't there another way around this?
<emx>
then the question is if there is a networkmanager installed.
<EdBr>
emx: Bus 002 Device 002: ID Obda: 8179 Realtek Semiconductor Corp.
<Vanfanel>
ssvb: The Cubie2 is supposed to be 3 times as powerfull in bot CPU and GPU than the Pi, so RetroArch, using GLES in both cases, should perform accordingly
<emx>
EdBr, k, so your device is running. what does ifconfig output?
<ssvb>
Vanfanel: 3 times more powerful for GPU? why would you think so?
<EdBr>
emx: yes it work, but not conect.
<Vanfanel>
ssvb: doesn't the Cubie2 have twin MALI400 GPUs? Maybe I'm mistaken...
<EdBr>
emx: when I enter in webpage I see "server not found"
<Fangorn>
Emx - i think they use network manager to connect
<emx>
EdBr, please post output of ifconfig
<emx>
Fangorn, i guess so.
* Fangorn
write to EdBr pm
<emx>
k
<Fangorn>
EdBr - you really can't open terminal?
<ssvb>
Vanfanel: doesn't Rpi have four (or sixteen?) GPU cores?
<Vanfanel>
ssvb: Yes, but all the GPU does here is to render a texture.
<EdBr>
emx: one minute because I have write in my notebook
<ssvb>
Vanfanel: on one hand it says "Videocoreiv Quad Processor Units", but on another hand it also says "Dualcore Videocore IV CPU @250MHz with SIMD Parallel Pixel Units (PPU)"
<Vanfanel>
ssvb: you simply have to build with GLES support and try an SNES game with the SNES9x-next core

<Fangorn>
Emx - think eth0 is down then cable out
<emx>
Wizzup, what do you mean by nodeps? i don't see that useflag.
<Fangorn>
EdBr - unplug cable and do ifconfig
<emx>
Fangorn, then why did he have an ip adress if he didn't configure eth0, i.e. when the ip is assigned dynamically to eth0?
<Fangorn>
I think they do ifconfig with cable
<Fangorn>
Nope?
<EdBr>
emx: ifconfig with cable and adapter wifi

<emx>
how stupid is it to start virtualbox with gentoo armv7a as guest and compile from there?

don't know, does virtualbox support arm emulation?

or what exactly do you want to achieve?

penghb has joined #cubieboard

emx: crosscompile what? the kernel is easy and fast
<ssvb>

<emx>
although they need to update chapter "boards" :P
FR^2 has joined #cubieboard

emx: the easiest way is just to buy some fast arm hardware and use it as a build machine :)
<ssvb>
emx: you can also compile natively on the cubieboard, but setup distcc
<ssvb>
emx: so that it would get a help from your desktop pc
<emx>
ssvb, so there are no architecture-limits in distcc?
<emx>
interesting.
<emx>
does it have to be another gentoo box?
<ssvb>
emx: obviously you have to setup distcc with an arm crosscompiler
<ssvb>
emx: yes, preferably another gentoo box, because you want the crosscompiler to be exactly matching the compiler from your arm device
<emx>
easier done than said.
<ssvb>
yes, that's why a fast arm build machine is the easiest :)
<emx>
ssvb, what is there on the market that is arm and fast? i only know about ondroid and wandboard.
<ssvb>
odroids are probably the best in terms of price/performance
<emx>
do they have a standalone nic-chip or is it a usb device?

Vanfanel: but I'm more worried that FBIOPAN_DISPLAY does not seem to work nicely with FBIO_WAITFORVSYNC and this likely points to a problem in the framebuffer driver
<ssvb>
Vanfanel: if you run the framebuffer gles program as 'strace -f <program-name>', you can see that the mali blob is doing FBIOPAN_DISPLAY as part of eglSwapBuffers
<ssvb>

I'm interested into the cubietruck because of its all-in own approach (cpu, flash, bt, wlan etc.)
<ssvb>
Vanfanel: hmm, nice, vsync seems to be also broken in libhybris now :)
<mifritscher>
how crucial is a stable 5V power? Or: what is driven directly by 5V despite usb and the SATA-device? And: are the voltage regulators linar ones or switching ones?
<mifritscher>
I'm asking because I'm wondering whether I can use the board on my little roboter which get its power from a USB accu
<Night-Shade>
mifritscher: I have mine running off a normal usb port with a SATA SSD
<Night-Shade>
I'm working it fairly hard building kernels etc
penghb has joined #cubieboard
<Vanfanel>
ssvb: maybe the drivers are getting an overhaul and that's why some important features are broken?
<mifritscher>
do you know how much power does it draw? I read that 500mA are enough for the board (without hdd) - if it's using lets say 300mA with enabled WLAN and sending a low res video stream from a USB-camera it would be great
<mifritscher>
I hat some problems with it on the carambola, that's why I'm asking
<Night-Shade>
if you are just wanting to send video there are better options
<mifritscher>
I'm planing to put ros on it ;)
<mifritscher>
but I don't think that ros needs much power
<Vanfanel>
ssvb: maybe I should stay away from the cubie2 (for GLES on fb stuff) until the mainlined is completed?

perhaps I'l play with olrsd as well

<Vanfanel>
ssvb: what does this sunxi_wait_for_vsync(disp) fn do under the hood? Does it also use the FBIO_WAITFORVSYNC ioctl then??
<ssvb>
Vanfanel: yes
<Vanfanel>
ssvb: thanks for the new example, really, but it's not the fix I need if it uses the same ioctl call that's causing me so much troube :P
wolfy has quit [Ping timeout: 252 seconds]
<ssvb>
Vanfanel: that's just an example of using disp layers via some thin wrapper functions (these functions are also used for implementing scaled tear-free video overlay for xf86-video-fbturbo)
<Vanfanel>
ssvb: I see :)
<ssvb>
Vanfanel: the only difference is that it is not using FBIOPAN_DISPLAY
<ssvb>
Vanfanel: and the sunxi disp layers seem to be working correctly with FBIO_WAITFORVSYNC
<ssvb>
btw, libhybris still also works correctly after all (I just forgot that I had vsync artifically disabled for gralloc to test the performance)
