Hello Chris,

for wired network, you should be able to add libbsd and start the
network similar like for all other boards.

Wireless is still some more effort. Note that you will need the
everything buildset of libbsd for that.

If you want you can have a look at the example application that I used
during the last GSoC projects:

    https://gitlab.com/c-mauderer/rtems-bbb/tree/master/apps/wifi-sample

That application starts a wpa_supplicant. It expects a RT8188EU based
WLAN dongle. There should be a wpa_supplicant.conf on the root of your
SD card. If I remember correctly it even routes between the networks. So
you could basically use the BBB as a Ethernet to WLAN adapter.

Best regards

Christian
