I have some news on this board.
On the wiki I paste the OpenWrt bootlog based when I flash the db120 image, here is the bootlog http://wiki.openwrt.org/toh/alfa.networ … rt_bootlog
As you can see in bootlog the phy interface is not recognized
[ 0.820000] libphy: ag71xx_mdio: probed
[ 0.820000] libphy: ag71xx_mdio: probed
[ 1.380000] ag71xx ag71xx.0: no PHY found with phy_mask=00000001
[ 1.930000] ag71xx-mdio.1: Found an AR934X built-in switch
[ 2.970000] eth0: Atheros AG71xx at 0xba000000, irq 5, mode:GMII
[ 2.980000] TCP: cubic registered
I cannot undestand why the iface probe failed. Any idea?
here some debug info

The eth0 port appear to be connected to switch0 internally at the SoC but no traffic flow probably because the internale switch canot probe the external phy chip AR8035-A
