Nios II/f "fast" core

Hello,

If I select Nios II/f "fast" processor core in SOPC builder then the result i'm getting is different (which is undesired output) than if i select Nios II/s "standard" core. Because of this i couldnt able to use Nios II/f "fast" processor core.

Can anyone help me to find a solution for this.

Tnx & rgds,

Shanchu.C

    Usually this comes down to your code not managing the data cache properly. If you bypass the data cache, you have to ensure that you either always bypass it for all the bytes in that line (4 bytes per line in the data cache) or flush the data cache.

    Maybe if you provide more details or code examples we can provide more help.
