UART

If you have an UART Link you'll be able to see those uboot messages : 

# Olimex micro eth .... uart0 { 3v, tx0, rx0 , gnd } .... power

linux-sunxi.org_images_thumb_1_1e_olinuxino_a20_uart_uart.jpg_360px-olinuxino_a20_uart_uart.jpg

This worked from me from RPI's UART to OLinuXino UART (3wires)

I used an Rpi as UART cable (dont connect vcc, just gnd and rx to tx in both way)

WIP

First, I could not boot it first because I needed a larger micro SdCard to put : 

archive=a20_debian_kernel_3_4_LAN_USBx2_Cards_LCD_HDMI_SATA_TS_X_GPIO_OTG_MIC_release5.7z# armhf wheezy
file=a20_debian_kernel_3_4_LAN_USBx2_Cards_LCD_HDMI_SATA_TS_X_GPIO_OTG_MIC_release5.img # 3980394496
disk=/dev/sdb # 3963617280 3965190144
time 7z e -so $archive $file | sudo dd bs=8MB of=$disk # 14m35.191s

See 1st part is starting 1MB ahead : 

# 1      1049kB  17.8MB  16.8MB  primary  fat16
# 2      17.8MB  3980MB  3963MB  primary  ext3

So let's format at repart our 4GB sdcard : 

sudo parted /dev/sdb -s resize 1 1MB 17MB
sudo parted /dev/sdb -s mkpart p ext3 17MB 100% 
sudo mkfs.ext3 /dev/sdb2
Did not boot . just got the Red LED on ...

Once Reparted SdCard ( keep space before 1st part) too add Uboot over it : 

# sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8

LINUX

Now it booted (using my RpI's UarT as SeriaL link : you can see Uboot messages ; and Standard linux dmesg
