Maybe I have a similar problem. While supported on i386, I can not get Am79C970A or
Am79C978 to work on EBSA285. Do these chips need an ARM adapted pcnet32 driver to work?
In my case I have bootp enabled. When bootp is sent, I do not get any interrupts, and
no packets on the ethernet wire. But later on, when bootp has done a number of retries
and timed out, I see a bootp packet on the wire and I get an interrupt. See below. Any
hints on what I could do to correct this?
(I have it working with other network adapters like DEC 21040.)
Thanks for any help,
Joakim
