Hi Buildroot mailing list,

My host is Ubuntu-14.04 LTS. My Buildroot release is 2015.05. I have made the former meet the latter's requirements. My target is Marvell ARMADA A385 (ARM-Cortex-A9) DB-88F6820-GP. Last week I succeeded in the building of the zImage file of my Linux system which has a rootfilesystem integrated, and a armada-385-db-ap.dtb file, The DB-88F6820-GP on-board U-Boot-1.73 commands are able to the boot up the system. The U-Boot bootargs string is:

"setenv bootargs console=ttyS0,115200 root=/dev/ram0 rw rootdelay=2"
But, I discovered, this system cannot enable the eth0 device at the boot time. The "Starting network..." messages are:

Starting network...
[    1.618607] mvneta f1030000.ethernet eth0: could not find the PHY
[    1.624732] mvneta f1030000.ethernet eth0: cannot probe MDIO busip: SIOCSIFFLAGS: No such device

Before I boot the system, the board's eth0 interface connects to a DHCP server. The attached is my .config. I am resolving this eth0-enabling issue. Your experience sharing is definitely welcome.

Tommy
