Subject: [openrisc] FPGA Board / Ethernet PHY
Thanks for ur answer..>That's a 10/100/1000 PHY, right?
yes, it is a 10/100/1000 PHY from national semiconductors..

I actually compiled the uclinux stuff and it is working with my simulator,
now i want to run compiled uclinux on my spartan board. I just checked
with my "make config" and didnt saw any supported national
semiconductors Ethernet PHY in the supported list. But i think that here
i am just going to see the Ethenet LANs? am i right??
>Either way, don't PHYs have a pretty standard interface?
>Shouldn't it be pretty trivial to add support?
First i also thought the same, till i asked somebody from the forum and
he told me that my ethernet PHY should be supported by my uclinux. I
actually also think that it should be trivial to support it.

i think the XSA-50 will be too small for my project. What i really want to
know maybe will be trivial:
i have a board with a big fpga (spartan 1800e)
it has Ethernet PHY for using the MAC
it has enough external memory for the uclinux
That mean i should be able to run my ethernet under uclinux?
I hope u r understanding what i mean..
Thank you for ur answer again,
best regards,
Mike
