I finally got the hardhat preview 2.1 linux boot on my 7410+107 custom
board.
Now I am trying to get the network work. The board has a 21143 MAC and one
intel
8-port PHY but the 21143 has no direct MDIO connection with such PHY.
The tulip driver did not complain about the 21143 during boot except I saw
the PHY LED
is blinking like crazy and of course I could not ping the target either.
1. How to disable all MDIO related operation from the driver? I just want
to configure
the device as MII mode and the PHY should work out of reset. This has been
proven
in our vxWorks based driver code.
2. How to correctly configure target ip address ? Is "ip=192.168.0.100"
enough ?
I saw something like "gw=255.255.255.255" in init log but I really don't
care gateway. All 1s look odd.
Thanks.
