Hi,

           I am still trying to bring up my board with Intel's TE28F128J3C150 
flash chip (8M in size). The Strata flash driver which came along with 
Redboot v1.92 is giving problem while programming.

          I tried with Prebuild version of redboot 1.94 executable also. No 
luck. I would be very greatful, if anyone of you give me the right 
direction... i m hanging over her from last 5 days :(.
