I've changed load address of initrd from 0x4600 to 0x4100 in
boot.scr and now SD cards seems to work ok, it's recognized by kernel as
was with older kernel.
I have one (or two) more question regarding those addresses. Which address
ranges are legal anyway for u-boot (placed in boot.scr)
There's 3.3V coming to A13. And 5V coming from A13 (now it's connected via
USB).
So I believe the voltage is right.

In all Mali based allwinner GPUs, and for the PowerVR ones later on:

Hi,
In Allwinner A20, what is the difference between Mali GPU and Mixer
Processor ?
Thanks and Regards,

Check with your hardware guy on the voltage of the TX line as you do not
want to be putting anything near 5V into the A20. It is not 5V tolerant on
the GPIO pins and will most likely damage the A20 IO.
The datasheet quotes the max input as 3.6V.

No rounding algorithm as such. Just go thro
Hi all,
I trying to use this image on OlinuXino A20 and work fine but i need to use
also on VGA monitor and also i changed uEnv.txt as README file say, it doesn't
work.
i tryed with
disp.screen0_output_type=4 disp.screen0_output_mode=1360x768
and also with
disp.screen0_output_type=4 disp.scr
Good day, Dave!
USB to serial is standard olimex female serial to USB cable. I've measured
the voltage on the pins, it is no more than 4.9V. I have no oscilloscope,
so don't know whether I can trust these numbers.
I'll forward the question to the hardware guy though.

Unfortunately, currently I don't have time for bisecting.
One thing that I forgot to mention is that I made initrd image with
'mkimage' option '-a 0x4500', if it means anything to you.
Another thing which I would mention is example from sunxi initial ramdisk
