Re: [microblaze-uclinux] SMSC 91c111 with microblaze over EMC
Hi George,
I'd like to use a direct (async) interface, if possible 32 bit (I heard
about problems with the 32bit mode)

I'm using the 91C111 on several of my devices. Which interface mode are
you using? ISA (async) 16 or VESA (sync) 32 or the direct 32 mode?

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,
