It is a useful technique and really hard to find. Trying to find a Linux embedded system with an IP address the jumps around (because it finds a 00 00 00 00 00 00 MAC address) can be very frustrating. Showing folks where they can give a non-NULL MAC address may save a lot of frustration. Doug Gilbert

So the u-boot environment file actually sets the MAC address. The Aria G25 has no NAND, flash or switches for setting a quasi unique MAC address. There seems to be no way to pass the MAC address on the kernel boot line (there was in the past). That leaves the microSD card and IMO u-boot is the best place to set that MAC address. My guess is that the Aria G25 is not the only board that has this "setting the MAC address" challenge. Finally of course that line is "board specific", that is why the file is called ariag25.dts :-) Doug Gilbert

If the mac is specifued in the register the kernel re-use it. This is the job of the booloader to set one. The dts in the kernel will be used for every Aria not one board in particular if you keep the mac addres in the dts NACK Best Regards, J.

Since when have MAC addresses been hw uniq? My guess is a huge majority of MAC addresses are set in firmware. Since many embedded systems with wired ethernet face this problem, is it the job of Linux to make this more difficult than it already is? > If the mac is specifued in the register the kernel re-use it. Unless u-boot (or whatever) edits the dtb file before the Linux kernel sees it. > This is the job of the booloader to set one. The dts in the kernel will be > used for every Aria not one board in particular It is the job of someone to set it. A MAC address can be compiled into u-boot but that is about as useful as compiling it into Linux kernel. > if you keep the mac addres in the dts NACK Seems strange to object to setting local-mac-address = [00 00 00 00 00 00]; when if the kernel sees that line it will do exactly the same thing as without that line? But the advantage of that line is that it gives the u-boot environment file the ability to edit the ariag25.dtb before the kernel sees it. And if the u-boot environment file is properly configured by the board manufacturer, then a quasi uniq, stable MAC address is generated.
