I bought 2 and fired up one up today with their distro
<focus_it>
The device has no NAND so relies solely on booting from uSD card.
<focus_it>
When I look at it, it has script.bin and kernel only on the uSD boot partition. A second partition contains root on the SD card.
<focus_it>
I want to try and boot from sata - where exactly do I change it?
<focus_it>
is it in spl? I'm reading http://linux-sunxi.org/U-Boot#Compilation but that is not clear where the environment may get set up to tell the linux to boot from /dev/sda
<focus_it>
I assume its an environment setting, but how is this environment saved into uboot? - that detailed bit of info is missing from that page :(
<focus_it>
Any pointers appreciated - thanks.

what do you guys think about the performance of rendering through EGL vs /dev/disp directly ?
<hramrach>
depends on your application. there is g2d too

it's for video rendering, after the picture is decoded, what's the best option ? framebuffer (may be easiest)? or EGL and then more feature as the drivers get better ?
<hramrach>
probably overlay
<pfdm>
ok thanks .

<wingrime>
hno: strange, "boot" command also behave this way
<hno>
wingrime, that smells like your kernel is returning to u-boot instead of starting. Are you sure the kernel imaqe is korrect?
<wingrime>
hno: but "env run bootcmd" boots normaly
<wingrime>
hno: If I do ext2load boot.scr and source , all behaves normaly
<wingrime>
or even I load kernel manualy and run
<wingrime>
hno: only auto start behaves incorrectly
<mnemoc>
so it's a buggy u-boot env?
<hno>
wingrime, "boot" and "run bootcmd" is exactly the same thing.
<wingrime>
but first work, and second not
<wingrime>
err,
<wingrime>
inverse
<wingrime>
)
<wingrime>
hno: oh, thats strange more
<wingrime>
hno: "env run bootcmd" works
<wingrime>
hno: "run bootcmd" hungs
<wingrime>
hno: "boot" - resetting
<wingrime>
mnemoc: thats maybe uboot, broke own memory
<hno>
wingrime, very very odd. env run and run is also exactly the same.

Hi guys, I'm reading http://linux-sunxi.org/U-Boot#Compilation - can't figure out which file need to be set with the default uboot environment - any hints?
<hno>
wingrime, gan be any kind of ghost. no ideas.
<hno>
focus_it, what do you mean?
<focus_it>
i'm trying to make the iteaduino plus board switch from booting from sdcard to sata - it has no flash - there is only script.bin and linux on the boot partition
<focus_it>
i don't know where to tell to let the card switch to boot from sata
<focus_it>
is it some file for spl or is it some file for uboot that needs to be set
<focus_it>
hno: There is a 2GB lxde image they build for it for sdcard, first partition has just the script.bin and linux while second partition has the rootfs.
<focus_it>
mnemoc: A10
<mnemoc>
focus_it: got any "OSHW" files?
<focus_it>
hno: no flash, so no idea how their device boots from sdcard and moves to the second partition
<focus_it>
mnemoc: OSHW = OS hardware files?
<mnemoc>
yes
<mnemoc>
they claim open source design, and the OSHW logo is all around
<focus_it>
i grabbed the script.bin and turned it into script.fex
<libv>
ah, oshwa.org, why did i miss that yesterday
<wingrime>
hno: thats defenetly something with default config
<hno>
wingrime, printenv kernel
<hno>
wingrime, printenv extraargs
<hno>
or better yet, printenv bootargs just before bootm
<hno>
wingrime, your not-working bootargs is nowhere near default settings. That looks like some attempt at getting an fbcons console running instead of serial.

I like the iteaduino because it has the separate CPU board.
<wingrime>
hno: as before sayed, non-worked settings are woring If I load it manual
<mnemoc>
hramrach: I almost broke 3 of the pins when removing the itead SoM :<
<hramrach>
what is the connector? Thre does not seem to be too much documentation
<wens_>
was there someone working on gmac for mainline?

the new cedar_dev allocate cached memory so we need to flush apparently each time

<wingrime>
rellla: so you have to fix libs around blob
<pfdm>
guys i've seen on the wiki that at term /dev/disp is gonna disapear ? So what the preferred method to render ( functionnalities and speed ) ?
<oliv3r>
focus: just in case nobody responded to you yet, you can't boot from sata on the A10/A20. We are planning to allow u-boot to load the kernel from sata, so you only need a small SPI flash with u-boot in it, but i'm not that far yet. you can boot from uSD and then load the kernel from sd and load your rootfs from satahowever

wingrime: yay! more cubietruck users :D you like it?

wens_: i don' tthink so; gmac is all for grabs
<mnemoc>
libv: he also posted it on the linux-arm list some days ago
<libv>
3 times?
<libv>
wow
<mnemoc>
libv: and he was pointed by... oliv3r? to the linux mainlining wiki page
<libv>
that's rather "special"... needs.
<oliv3r>
libv: omg Alexey IS an idiot
<oliv3r>
i bet he never visited linux-sunxi.org even though he links the site :)
<oliv3r>
mnemoc: what did I do?!

oliv3r: sorry, it was arokux1

some one really lazy in doing their research

mripard response was kind of sad stating we only care about 3.4
torindel has joined #linux-sunxi
<oliv3r>
i care about both
<oliv3r>
i want mainline, but we need 3.4 for full featured support today
<libv>
mnemoc: heh, mainline fetishists.
<oliv3r>
there's not enough time/resources to do mainline faster
<oliv3r>
but my side project is almost done
<ssvb>
oliv3r: this Alexey guy also linked to a rogue site, which is reselling cubietrucks at a higher than normal price
<oliv3r>
noob
<ssvb>
failed in every possible way
<oliv3r>
it's highly frustrating though when he did so little research
<mnemoc>
maybe it's his way of promoting his overpriced shop....
<mnemoc>
spam takes weird forms these days
<oliv3r>
he probably just randomly googled for it
wingrime has joined #linux-sunxi
<mnemoc>
ok. let's blame hanlon's razor
<oliv3r>
but lets look at it from the positive side, konstantinos seems to be interested, so if that brings him to sunxi and working on it; it's still a win
<mnemoc>
:)
<oliv3r>
The kernel is supported at sunxi.com.
<oliv3r>
and we do have some form of reference
