Hi,

 

The ethernet PHY of my new-board is AR8033, and I use the same u-boot-imx.bin to test the new-board and SabreSD by following commands,

setenv ethaddr 00:04:9f:02:b7:fb
setenv ipaddr 192.168.203.14
ping 192.168.203.203

 

The network function works well for the SabreSD, but the network function does not work for the new-board, following message shows up continuously...

ARP Retry count exceeded; starting again

 

For the SabreSD , the following u-boot message shows up

Net: FEC [PRIME]

 

For the new-board, the following u-boot message shows up

Net: Phy not found

PHY reset timed out

FEC [PRIME]

but the command "mii dump" still works, the following message is identical with SabreSD's

0.     (ffff)                 -- PHY control register --

  (8000:8000) 0.15    =     1    reset

  (4000:4000) 0.14    =     1    loopback

  (2040:2040) 0. 6,13 =   b11    speed selection = 10 Mbps

  (1000:1000) 0.12    =     1    A/N enable

  (0800:0800) 0.11    =     1    power-down

  (0400:0400) 0.10    =     1    isolate

  (0200:0200) 0. 9    =     1    restart A/N

  (0100:0100) 0. 8    =     1    duplex = full

  (0080:0080) 0. 7    =     1    collision test enable

  (003f:003f) 0. 5- 0 =    63    (reserved)

 

Is there any idea ?
