Cache enable creating problem for ethernet driver

Subject: [ECOS] Cache enable creating problem for ethernet driver

Dear All,


I am using Hitachi SH3 7729 processor + ecos 2.0. Basic application is working on my new hardware without any problem. Now I am incorporating ethernet driver (SMSC LAN91C111 available with ecos 2.0) in my application.
But ethernet driver initialization fails when I enable "Enable cache on startup" option of SH architecture.
I feel this is the problem of operating speed difference between main controller & ethernet controller. I also tried to increase the wait state for ethernet area section. My application is designed with "Enable cache on startup" option set.

I want to run the complete application with "Enable cache on Startup" option set. what are the changes I need to do in ethernet driver ?

pls guide me to solve this problem.


Thanks in Advance


Aniket Joshi
