=== Clusterboard Ethernet === | |||
It appears that Ethernet with the [https://www.pine64.org/clusterboard/ pine64 clusterboard] requires [https://forum.pine64.org/showthread.php?tid=10432 a slightly modified device tree to work]. There's some conflicting information about exactly what is needed to get Ethernet working but currently, mainline linux (5.4.58 at the time of testing) plus a modified device tree is sufficient to get a full speed 1gbps connection. | |||
First create the device tree overlay. | |||
<pre> | |||
/* sopine-baseboard-ethernet.dts */ | |||
/dts-v1/; | |||
/ { | |||
model = "SoPine with baseboard"; | |||
compatible = "pine64,sopine-baseboard\0pine64,sopine\0allwinner,sun50i-a64"; | |||
fragment@0 { | |||
target-path = "/soc/ethernet@1c30000"; | |||
__overlay__ { | |||
allwinner,tx-delay-ps = <500>; | |||
}; | |||
}; | |||
}; | |||
</pre> | |||
Create the device tree binary from that. | |||
<pre> | |||
dtc -O dtb -o sopine-baseboard-ethernet.dtbo -b 0 sopine-baseboard-ethernet.dts | |||
</pre> | |||
And add it to your configuration.nix | |||
<pre> | |||
... | |||
hardware.deviceTree.enable = true; | |||
hardware.deviceTree.overlays = [ | |||
"${/path/to/sopine-baseboard-ethernet.dtbo}" | |||
]; | |||
... | |||
</pre> | |||
