bprinz Posted May 30, 2017 Share Posted May 30, 2017 Hi, after the update from Armbian 5.23 to 5.25 on a Banana Pi M2+ board, the MAC address and CPU serial number have changed. This can be reproduced by just updating the u-boot package on Armbian 5.23: # ifconfig | grep HWaddr eth0 Link encap:Ethernet HWaddr da:c7:a0:49:24:d6 # grep Serial /proc/cpuinfo Serial : 2435501d0a0e4800004d # dpkg -i linux-u-boot-bananapim2plus_5.25_armhf.deb # reboot # ifconfig | grep HWaddr eth0 Link encap:Ethernet HWaddr 3a:89:a1:23:98:a6 # grep Serial /proc/cpuinfo Serial : 24005035871c481d0a0e Does anyone know the reason for this? Did u-boot change the way these numbers are generated? Best regards Link to comment Share on other sites More sharing options...
