Hey @clem_ent,
I wanted to share the configuration trick that I used to establish a network connection with espressobin.

First, the Marvell Yocto project is not based off Yocto’s poky distro, but from O.S. Software System’s distro named oel. You can see this under meta-marvell-distro/conf/distro/marvell.conf https://code.ossystems.com.br/gitweb?p=meta-ossystems-base.git;a=blob;f=conf/distro/include/oel.conf;h=a87da9b9cf2958b60f04df8ea96f39ba44f83d27;hb=refs/heads/krogoth

I mentioned the distro, because it looks like the oel distro uses SysVInit as the start up service for their Linux images. My configuration trick is for Systemd, but the changes can be implemented to /etc/network/interfaces file for SysVInit.

Under /etc/systemd/network, I added the following network files:

root@espressobin:/etc/systemd/network# ls -al

drwxr-xr-x    2 root     root          4096 Jan 23 18:14 .

If you’d like to learn how to re-build your Marvell Yocto project with systemd, I can share these build configuration changes but then you may be outside the realm of marvell yocto support.

Cheers.
