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

[Matthias Heise <m.heise@xxxxxxxxx>]

Hi Vijai,
no, I'm afraid I am stuck far earlier, I can't even write and read the 
registers . Did you infact connect the chip successfully to a microblaze 
system directly over an emc ? This would be very interesting for me 
especially the pin connections at this stage. Do you use uClinuc or do 
you try to write a driver and Stack yourself for the "bare" microblaze 
as I'm supposed to do ? Could you send me your project by any chance ?
Thanks for your answer anyway,
Matthias
