Ethernet connection doesn´t work

[Hirbl]

I was on commissioning SKIPR Board and tried to connect via Ethernet. I was able to access via SSH but after some updates connection via Ethernet was lost.
Also a try with a new default image on EMMC module from decribed google docs link wasn´t successfull.
Any chance to do reset an the board?

Are there any possibilities to get access to board?
