Hi Axel
How did you fix your console problem? I have the same issue:
This config says starting kerneland then nothing
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait panic=10
${extra}
fatload mmc 0 0x4600 uImage
fatload mmc 0 0x4900 sun7i-a20-olinuxino-micro.dtb
e
Enable early printk in the kernel debug section on menu config. Then
add it to the command line from uboot.
Kernel command line: console=ttyS0,115200 loglevel=9 earlyprintk
root=/dev/nfs
ip=192.168.1.51:192.168.1.254:192.168.1.254:255.255.255.0:truck::off
nfsroot=192.168.1.50:/export/work/root ro
Thanks Jon, I have cleared my sdcard and setup tftp/nfs etc.
The exercise has shown I have a uboot/hardware problem in that the network
is not working
If I build uboot using "cubieboard2" I don't even get a "link up"
If I build uboot using "A20-OLinuXino_MICRO" ... I at least get link
up..
Turn on the earlyprintk support. That will likely make some error
messages appear.

Doesn't helpwhich suggests I'm doing something fundamentally wrong.
bootargs=console=ttyS0,115200 loglevel=9 earlyprintk
In my defconfig I have:
CONFIG_PRINTK_TIME=y
CONFIG_EARLY_PRINTK=y
CONFIG_DEBUG_LL=y
CONFIG_DEBUG_FS=y
The board I'm using in A20-SOM-EVB ...which was only released in May
Maybe you are loading the DTB too close to the kernel and when the
kernel expands it over writes it

Hi Maxime
Nope... didn't think about damaging the board. I have absolutely no
idea what I'm doing :) ...it's just a hobby and I figured the only way to
learn is to try.you really don't want to watch me connecting the
breadboard LOL
