Is there a version of 0.7.0 still on Git? 0.8.0 just isn't working for me at all. No matter how I try to work around it and static ip it, it just doesn't respond with any form of IP on 0.8.0 not sure what gives, just put raspbian on there and it runs right off the get go.
0.8.0 has latest Raspbian Stretch, if the Raspbian image (latest) works for you start from that then run the manual install on it.
Just get a terminal and run:
curl -o- https://raw.githubusercontent.com/getminera/minera/master/install_minera_ubuntu.sh | sudo bash
It must be a fresh Raspbian install
