[Cubieboard2] Network interface is down after system uprgade

[makoven]

Hello.

A couple of days ago, I upgrade archlinuxarm on my Cubieboard2. After rebooting, I could not connect to it via ssh. I have connected via COM-port and found that the network interface is DOWN.

I wrote in the terminal:
$this->bbcode_second_pass_code('', 'ip link set dev eth0 up').

Then lines appeared in the terminal :
$this->bbcode_second_pass_code('', '
<6>sunxi_emac sunxi_emac.0: eth0: link up, 100Mbps, full-duplex, lpa 0xC1E1
[ 114.555743] sunxi_emac sunxi_emac.0: eth0: link up, 100Mbps, full-duplex, lpa 0xC1E1
')

After that eth0's state becomes UNKNOWN and ssh has worked.

But after rebooting, I could not connect to it via ssh again.

Please, help

check here. Seems the same kind of problem to me. Maybe worth looking at

try
$this->bbcode_second_pass_code('', '
systemctl enable dhcpcd@eth0.service
')

I have had some problems on my CubieTruck too. Changing to a custom kernel helped me. I reported my struggle here. The relevant part:

$this->bbcode_second_pass_quote('', '(')…)Network can be manually brought up after modprobing sunxi_gmac. Sadly persisting static IP address following this guide does not work. But executing systemctl start network@eth0 after reboot manually works. Why so?

Edit 3:
After updating to dan-and's kernel 3.4.106 it seems to work. Network gets up on boot and above mentioned static IP configuration works also.(…)
