BeagleBone Black Rev B + C Ethernet DHCP

[Justin Schneck]

Hello,

I just started to get nerves-sed and the nerves-demo up and running on my bbb. I have both a Rev B and a Rev C.

I think I am encountering a newbie problem, but I am having trouble getting it to resolve an ip address. Is there a configuration that I need to set?

Thanks!

Hi Justin,

By default, nerves doesn't help with IP setup. This is something that
I've wanted to address, but just haven't had time. If you want to just
assign an IP address, you can do something like:

os:cmd("/sbin/ip link set eth0 up"),
os:cmd("/sbin/ip addr add 192.168.1.40/24 dev eth0"),
os:cmd("/sbin/ip route add default via 192.168.1.1"),

If you use Elixir, I have some work-in-progress code that may be of
interest. (I haven't had time this past month to work on it, but there
might be something helpful in it.) See the following repositories:

https://github.com/fhunleth/net_basic.ex
https://github.com/fhunleth/wpa_supplicant.ex

Hope this helps,
Frank

Thanks Frank,

shortly after posting I re-watched your video on the getting started page, this time with the sound turned up. :)

I started a new elixir project and called out to the erlang code you referenced below in the application start. Everything seems to be working. Thanks for the response and for your work on the nerves project, there is nothing more exciting than having some minimal erlang on my beaglebone black.
