Hi there,

Where do I assign a static IP address to my sole network interface?

That depends on whether or not you are using a network manager and if so which one.

You haven't told us much about your board and it's network interfaces and how you built your system.

I tried using the Linux boot parameters (in extlinux.conf):

LABEL Arria10 SOCDK SDMMC
    KERNEL ../zImage
    FDT ../socfpga_arria10_phead.dtb
    APPEND root=/dev/mmcblk0p2 rw rootwait earlyprintk console=ttyS0,115200n8 ip=192.168.0.101:255.255.255.0:eth0

 

Then I tried editing: /etc/network/interfaces

 

iface eth0 inet static
address 192.168.0.101
netmask 255.255.255.0

 

Both failed. Where do I go?

To start, do you have the driver required for your network interface? You can use ifconfig -a to see if your network interface is detected by the kernel. You should also look at the kernel log if the network interface is configured.

Yes, the network/Ethernet device is recognized by Linux and the appropriate driver is loaded. If I use:

$ ip add add 192.168.9.101/24 dev eth0

I’m up and running. But I want the IP assignment to happen during boot time.

Hello,

Maybe you can stop in the U-Boot monitor, and check your environment?
=>
=> print serverip
=> print ipaddr
=> print gatewayip
=> print gw_ip

And see what and how your bootcmd and similar env variables look like?

And if you do not have defined above, to add them (according to ash
script) and try booting again?

What is your startup manager? systemd or SysVInit?

systemd

Create the file /etc/systemd/network/eth0.conf:

[Match]
Name=eth0
[Network]
Address=<ip>
Gateway=<ip>
DNS=<ip>

Restart systemd-networkd

# systemctl restart systemd-networkd

or reboot.

Create the file /etc/systemd/network/eth0.conf:

[Match]
Name=eth0
[Network]
Address=<ip>
Gateway=<ip>
DNS=<ip>

That didn't work BUT editing /lib/systemd/network/80-wired.network

[Match]
Name=en* eth*
KernelCommandLine=!nfsroot

[Match]
Name=eth0
[Network]
Address=192.168.0.101/24
#Gateway=<ip>
#DNS=<ip>

[Network]
DHCP=no

[DHCP]
#RouteMetric=10
#ClientIdentifier=mac

... did work, after:

root@arria10:~# systemctl restart systemd-networkd

Preferred method for local configuration is using /etc/systemd/network. However, the probable reason why it did not work is that the file should be eth0.network. The name of the file(s) do not matter that much. The extension does though.

Can this be done using boot parameters?

Not that I know of. Why anyway?

Something like(?):

LABEL Arria10 SOCDK SDMMC
    KERNEL ../zImage
    FDT ../socfpga_arria10_phead.dtb
    APPEND root=/dev/mmcblk0p2 rw rootwait earlyprintk console=ttyS0,115200n8 ip=192.168.0.101:255.255.255.0:eth0
