Duplicate MAC Addresses and Serial Numbers


#41

Can you paste full printing log for us? Just worried you ran the command on Linux, it should be on U-Boot.

Have fun!


#42

What ja u bot… i have a debian.


#43

I meant U-Boot, the booloader of any Linux Distro(Ubuntu, Debain…)

So you ran the command on Linux, right? Should be on U-Boot :wink:


#44

Hello Emill,

What image you use? If you use linux image provided by us or Armbian by balbes150, you can try the following commad on linux command line:

$ sudo fw_setenv ethaddr “00:15:18:01:81:32”

Thanks.

#52

You still working on Linux/Ubuntu, not U-Boot :joy:


#53

what did I write above? I have ubuntu… and you write uboot uboot and uboot all the time …

I do not have the strength to do it anymore, you do not help … I return to raspberry pi, there are no problems, I only wish I have 20 khadas bought, but I will refund


#54

Nobody can help you out if you don’t want to give a try.

Actually, Ubuntu also include a U-Boot as bootloader, please follow the instructions I told you to take a try and update us if further questions.

Good luck!

#56

You’ve been given 3 working options - they all work with an Ubuntu based board - ive used them all!

  1. in the file /etc/network/interfaces add a line hwaddress ether XX:XX:XX:XX:XX:XX where XX is your MAC address. Reboot to get it to pick up the MAC
  2. sudo fw_setenv ethaddr “00:15:18:01:81:32” that sets uboot variables from the ubuntu command line
  3. go into uboot - @Gouwa gave you the links, just need to follow them - get a serial to usb adaptor connected as per https://docs.khadas.com/vim1/SetupSerialTool.html then from a serial console on your pc press space whilst the board is booting at you will halt boot at the u-boot prompt then you can use the command - setenv ethaddr “00:15:18:01:81:32”

If you dont know what something is then you can just google it - https://en.wikipedia.org/wiki/Das_U-Boot

Hi Emill:

  • Ubuntu or Armbian is an Operating System
  • U-Boot: is a bootloader, not an Operating System, check the link birty replied above for the details.
  • All Operating System will require bootloader/u-boot, and the UBuntun you install also with a U-Boot

Have fun!


#58

okey, now i know what i u-boot, tell me how install u-boot with system? i have files, but dont know how use in ubuntu.


#59

Uboot is already installed, it’s what loads Ubuntu for you. Personally I would ignore uboot and use either option 1 or 2 that I put above. Both of them work from within Ubuntu


#60

Method 1 not working, i try many times, many methods.
Method 2
$sudo fw_setenv ethaddr “00:15:18:01:81:32”
without mistakes but without results
