Re: [microblaze-uclinux] SMSC 91c111 with microblaze over EMC

[Vijai.S.Kumar@xxxxxxxxxxxxxxxx]

hi
actually we are also trying SMSC MAC+PHY but the problem here is as -

we are able to register the device and everything is OK
but when we ping the system itself it is also Ok.
but we are not able to receive the data from outside.
after ping if we run ifconfig we get 100% loss in eth0 but in "eth lo" we
get 100% sent and receive.

is the same problem ur having??.

Hi ,
I connected the smsc macphy chip over emc to my microblaze system and
can write out addresses and data on the correct lines (tested them all
with oszilloscope :-( ) . Then I try to write and read the registers
just as described in the smsc application note 9.6. But obviously the
data isn't taken in by the chip as I only read the same values, no
matter what I write. There is activity on the read and write enables. A
classic would be the reset line, can anyone confirm that it is (most
unusual) high-active ? I couldn't find any information saying that it is
low though. Anyway I'm stuck. Any helpful ideas ?
Thank you,
