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

[Matthias Heise <m.heise@xxxxxxxxx>]

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,
