Re: [microblaze-uclinux] CS8900 10Mb Ethernet

[johan@xxxxxxxxxxxxxx]

Hi Aurash,

I am the one who have developed the IP interfacing a cs8900. It is in fact a 
bus bridge between OPB and ISA. It works as it should as far as I know. 
Unfortunately the CS8900 chip didn't arrive before I left Australia (I'm on my 
way back to Sweden). I made some other tests though, I made an on-chip ISA GPIO 
that had the same functionality as the OPB GPIO (but much more simplified), and 
it seemed to work fine.

John has the core, and so do I. But I can't give it to you before I'm back in 
Sweden. Is this something that would be of interest for you? I can give you 
some support on the core when I'm back home. I am also very interested in 
learning about bugs that you might find.

Cheers
Johan
