"Timing issue when we use SPANSION 8MB Flash"

[Vitaly Wool]

Hi,

am I right that it's a NOR flash? What's the reason for using JFFS2 on 
it then?
Also questionable is whether you're sure that you have right timings 
configuration for the flash. I'm afraid that 8MB Spansion flash might 
have timing values different from 4 MB's.

Best regards,
   Vitaly
