My Problem is quite simple I hope.
I compiled the Yocto image “marvell-image-machine-test” and flashed it on my espresso. I plugged it to my ethernet switch and i cannot get any address from my dhcp server to validate network connectivity on the board.
I tried to set up a static ip to eth0 and test a point to point connection with my laptop. Again, no communication.
Is there a configuration trick that i am missing ?
I have the same problem. This seems might be a kernel related problem. Plugging/unplugging a cable doesn’t seem to be noticed by the kernel (nothing in dmesg). Maybe
The only logs about the MV-88E6341 I have are the following:
[ 5.454962] libphy: mv88e6xxx SMI: probed
[ 5.458792] mdio_bus d0032004.mdio-mi: switch 0x341 probed: Marvell 88E6341, revision 0

[ 5.776342] Generic PHY mv88e6xxx-0:03: attached PHY driver [Generic PHY] (mii_bus:phy_addr=mv88e6xxx-0:03, irq=-1)
The “irq=-1” seems suspicious, but it may be normal.
Strangely, I have some interfaces (eth0, wan0@eth0, lan0@eth0, lan1@eth0)
Edit: I succeeded to have an ip manually on wan:
# ip li set up eth0
# ip li set up wan
Then, I used some dhcp on wan and it worked.
But, setting up eth0 triggered some messages from the kernel:
[ 84.485771] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 86.252156] mvneta d0030000.ethernet eth0: Link is Up – 1Gbps/Full – flow control off
[ 86.260241] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 90.616631] dsa dsa@0 wan: Link is Down
[ 92.629555] dsa dsa@0 wan: Link is Up – 1Gbps/Full – flow control rx/tx
Finally, it’s maybe just a wrong settup from my side.
Ok, it’s not a kernel problem at all, I just messed up my network configuration. I use systemd-networkd and after cleaning/updating files in /etc/systemd/network/ my setup works fine.
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 total 32 drwxr-xr-x 2 root root 4096 Jan 23 18:14 . drwxr-xr-x 5 root root 4096 Jan 4 21:39 .. -rwxr-xr-x 1 root root 30 Jan 4 21:50 10-br0.netdev -rwxr-xr-x 1 root root 38 Jan 4 21:50 10-br0.network -rwxr-xr-x 1 root root 40 Jan 4 21:50 10-eth0.network -rwxr-xr-x 1 root root 40 Jan 4 21:50 10-lan0.network -rwxr-xr-x 1 root root 40 Jan 4 21:50 10-lan1.network -rwxr-xr-x 1 root root 40 Jan 4 21:50 10-wan.network 10-br0.netdev [NetDev] Name=br0 Kind=bridge 10-br0.network [Match] Name=br0 [Network] DHCP=ipv4 10-eth0.network [Match] Name=eth0 [Network] DHCP=ipv4 10-lan0.network [Match] Name=lan0 [Network] Bridge=br0 10-lan1.network [Match] Name=lan1 [Network] Bridge=br0 10-wan.network [Match] Name=wan [Network] Bridge=br0

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.
Thanks for the tip.
I managed to get network working by using a mainline device tree for the espressobin. Unfortunately, i can only see eth0 interface.
I’ll try to deploy systemd on my yocto and use your trick !
Just a question though : can your interfaces have a different IP address ?
You can try to update your /etc/network/interfaces file with the following code snippet to enable the wan, lan0, lan1 interface ports. This way you won’t have to re-build for systemd.
auto lo br0 iface lo inet loopback allow-hotplug eth0 iface eth0 inet manual allow-hotplug lan0 iface lan0 inet manual allow-hotplug eth1 iface lan1 inet manual iface br0 inet dhcp bridge_ports lan0 lan1 wan
With my current systemd-networkd configuration, I am able to plug-in an Ethernet cable between the wan, lan0, & lan1 ports and my network connection is retained. When switching ports, I get the following output:
root@espressobin:~# [ 571.902010] dsa dsa@0 wan: Link is Down [ 571.905604] br0: port 3(wan) entered disabled state [ 579.018470] dsa dsa@0 lan0: Link is Up - 100Mbps/Full - flow control rx/tx [ 579.025461] IPv6: ADDRCONF(NETDEV_CHANGE): lan0: link becomes ready [ 579.039239] br0: port 2(lan0) entered blocking state [ 579.044227] br0: port 2(lan0) entered forwarding state
Since my network ports are bridged with the bridge set to DHCP and all the network interface ports are on the same nic, the IP address is the same when switching between interfaces. I’m able to configure the bridge to a static IP address. There may be a way to set a different static address to the bridge depending on which network interface port is connected, but I am unfamiliar with how to correctly set-up that kind of network configuration. My first thought would be to look at defining a udev rule to handle this, but there may be a better option. Let me know if you are able to get a different ip address for each interface, I’d be interested to see how the network is configured.
Thank You it worked with systemd ! I am able to communicate between two networks.
I saw this post and have the same problem.
I can’t connect the espressoBin board to the PC with an ethernet cable and can’t ping to a website.
I follow the network config from this wiki page: http://wiki.espressobin.net/tiki-index.php?page=Ubuntu+-+initial+network+configuration
and get this error when running:
root@localhost:~# apt-get install bridge-utils
Reading package lists… Done

Selecting previously unselected package bridge-utils.
dpkg: unrecoverable fatal error, aborting:
files list file for package `iputils-ping’ contains empty filename
E: Sub-process /usr/bin/dpkg returned an error code (2)
So, I can’t set the iptables or brctl because I can not install them.
Also, I follow the routing documentation from this page:http://wiki.espressobin.net/tiki-index.php?page=Buildroot+-+initial+network+configuration
But, I can’t find the BR2_PACKAGE_DNSMASQ in the make menuconfig from kernel 4.4.8 to enable dnsmasq and copy it to sdcard.
I followed the solutions from above but they didn’t work for me. If you managed to set up the correct PC-espressoBin connection, can you share the steps?
