I don't have such problem on my Odroid XU3 which also performs netboot (Arch ARM Linux): netboot=tftpboot 0x40008000 zImage; tftpboot 0x44000000 exynos5422-odroidxu3-lite.dtb; bootz 0x40008000 - 0x44000000 TFTP from server 192.168.1.10; our IP address is 192.168.1.11 [ 0.000000] Kernel command line: console=tty1 console=ttySAC2,115200n8 root=/dev/mmcblk0p1 rootwait rw no_console_suspend smsc95xx.macaddr=00:1e:06:61:7a:93 Do you have anything connected to USB ports of the devices? For example on boot-exynos5250-arndale.html I see: [ 2.792934] using random self ethernet address [ 2.797209] using random host ethernet address [ 2.802244] usb0: HOST MAC 46:52:cf:b5:0f:e8 [ 2.805923] usb0: MAC a2:04:5d:a6:2c:fa [ 2.809720] using random self ethernet address [ 2.814137] using random host ethernet address [ 2.818599] g_ether gadget: Ethernet Gadget, version: Memorial Day 2008 [ 2.825159] g_ether gadget: g_ether ready It looks like that's the difference.
