A20 not booting android from Nand

[Ruler]

Hi,

I recently bought a A20 board and when I tried to boot it I got no video on the HDMI.
So I connected the UART0 to see what's going on.  This is the console log

I can type a few commands but then the board becomes unresponsive (if I wait more than 3 sec before entering a new command).

As a TTL conveter I use this board:

It is supposed to boot android by itself right?


Please advise,

Kind regards,

Roel

Mine does boot Android. Trouble at first because the power supply was too weak.  Dies during boot.
Then, when Android boots, there's a short time-frame to unlock it (pull the lock left/right/whatever on the screen) before it shuts back off in power-saving mode. This was just a few seconds for mine.
I think that's what's happening on your board.  I'm using a 10" LCD and that worked 'out of the box'.  Haven't tried HDMI yet, need a cable. 
If you can unlock it and set the timeout higher, that should help.

[Ruler]

Thanks for you reply. I'm using a 12V PSU capable of running 3 amps so I should be more than ok with that. I have no LCD screen yet. Is there anyway to set the HDMI as the primairy display?

Could you paste me the output of your UART0 during boot?

I'm using a keyboard and mouse plugged into a hub with an USB Ethernet.

I'll have a look at HDMI. I need to plug some stuff together for that.

[Lurch]

I see that there is a large delay between flash init start and finish on your bootlog.
Strange. Almost 2 seconds.

[Ruler]

Update. Well finally got it working!  Turns out because I didn't have the mouse connected it gave no video on HDMI. When I finally had video everything was in japanese characters though   But I managed to change the language back:)

Thanks for the effort man

[rz2k]

I have no LCD screen yet. Is there anyway to set the HDMI as the primairy display?

A20 is sunxi series processor, you can use android external screen detection (if it works) or you can grab script.bin from your /dev/block/nanda partition (mount it as vfat), decompile it with "bin2fex" from sunxi-tools package, then read http://linux-sunxi.org/Fex_Guide, change the display section settings, you can use HDMI, LCD or VGA outputs with variety of resolutions and compile it back with "fex2bin". "fex" here is file format that looks like .ini files from Windows.

Hello, I got a mars board with A20 processor. I tried to boot from NAND but kernel doesn't boot, the boot log is pasted below:

[junetec]

D'ont work on mine.
My sd card has the script to output to the 10" LCD.
I don't know if that can be a problem.
