![]() See the documentation on U-Boot Environment Variables. Note that in some systems the ethaddr variable is used by U-Boot itself to configure the MAC address of the first network device, and the Linux network driver may continue to use that address, so you don't need to explicitly pass it into the kernel. One way is to press and hold the Option key on your keyboard and click the Wi-Fi icon ( ) in the top right-hand corner. On a windows box, from a DOS prompt you can type 'arp -a' to see similar output. On a cisco router, the command is 'show arp' - it will give you a listing of the MAC addresses and their corresponding IP address. Typically, eth0 is for Ethernet connection, and wlp2s0 for Wireless connection.I want to change a mac address at the u-boot level like the following. If there is a router in your network, this is usually the most central place to gather that type of info. Step 2: In CMD, type the command ipconfig /all and then press the Enter key. ifconfig is deprecated on Linux, so you should use ip.
