I was chatting with someone last week regarding flashing images to the onboard flash on the iTeaduino, and we were both having issues with it.
<Rhys79>
I figured out the problem if anyone is interested :)
<Rhys79>
Also, is the cubieboard site down? I can't seem to access it???
<megal0maniac_afk>
I came right, but I'd like to hear what your problem was

There is no physical uBoot button on the Core or Baseboard. You have to use a jumper wire to short the uBoot pin to ground. Pin 102 on the core, pin 139 on the baseboard.
<megal0maniac_afk>
Aha... What button had you been pressing then?
<megal0maniac_afk>
The ibox has a uboot button, thankfully
<Rhys79>
I had been pressing the reset and/or power button apparently.
<megal0maniac_afk>
:)
<Rhys79>
It looks like they updated the docs to better label the buttons and I finally figured out what they were, then looking at the pinouts, I found the uBoot line.
<megal0maniac_afk>
Yeah, Jerry is very busy. I get the idea he's the sole developer
<Rhys79>
Just reflashed the onboard memory with a cubieboard2 lubuntu image, was about to hook it up and see if it works.
<megal0maniac_afk>
He is actually doing stuff, but a little bit at a time
<megal0maniac_afk>
Also, I just built the kernel. But there is no "output" directory anywhere
<megal0maniac_afk>
I followed the instructions exactly, with the exception of cross-compiling as I did it on the device. But this points me to files that don't exist: http://linux-sunxi.org/Linux_Kernel#Install
<megal0maniac_afk>
Apparently I need to copy modules. But they are nowhere to be found
<Rhys79>
Hmmm, tries to boot now. Get a terminal spew. Last line is an error "init: ureadahead main process (70) terminated with status 5" and it's stuck there.
<Rhys79>
I was able to cross compile a kernel on an Ubuntu VM without too much trouble.
<megal0maniac_afk>
I did a find * | grep modules and came up with nothing :/
<megal0maniac_afk>
And didn't back up the original uBoot :P
<megal0maniac_afk>
Oh well
<Rhys79>
Holly shit, after sitting there forever, it finally booted :)
<megal0maniac_afk>
Yay!
<Rhys79>
Now, wonder what the default password is....
<megal0maniac_afk>
Hopefully mine will boot too. I don't understand the Linux kernel well enough to know what will happen
<megal0maniac_afk>

(Those are both passwords)
<Rhys79>
Yay, booted and logged in :)
<megal0maniac_afk>
Nope. Mine will not boot
<megal0maniac_afk>
I broke the kernel. Sigh.
<Rhys79>
oops lol

Also, they sent me the expansion board which breaks uart0 out into USB through a CP2102, which is useful in theory because now I have a micro USB debug port, but in practice the stupid thing keeps dropping out
<megal0maniac_afk>
As if I've unplugged it
<Rhys79>
That's odd
<megal0maniac_afk>
The grove connectors had a dry joint each, so I think there might have been too little solder on the board
<megal0maniac_afk>
Datasheet suggests all supporting circuitry is here
<megal0maniac_afk>
Although with a long cable it won't even enumerate
<Rhys79>
I have to design my own baseboard.... need VGA and they neglected to to pull those lines off the core to the headers on the Plus baseboard.
<megal0maniac_afk>
That's odd...

The ibox headers are reasonable, except a lack of standard GPIO

Yeah, kinda sucks. And the core headers are so tiny, I don't want to try to solder to them directly.
<megal0maniac>
Oh goody! it works. I was going by the LEDs
<Rhys79>
I want to hook it up to an old 12" 800x600 VGA input touch screen monitor with a 3M resistive touch overlay on it, but I have no way to access the VGA out with the existing baseboard....

It's a bit of a pain. If I want VGA, I need to make a PCB anyway

I was planning on building a baseboard anyways. I want to use the core as the head-end of a 3D printer control design. Was planning on building a baseboard with a Mega2560 and stepper drivers on it, and integrate the whole thing onto the monitor. Big fat pigtail connector to hook to the 3D printer and off it goes :)

hm?
<buZz>
qemu 2 has 'cubieboard' emulation?
<rm>
It certainly looks that way. (c)
<buZz>
:)
<buZz>
nobody has played with it yet?
<rm>
I'll wait till QEMU 2.0 is in debian
<buZz>
i'm tempted to try it out
<buZz>
but guess i will continue my other allwinner project
