As I've seen, it seems that the boot_loader initalizes the iCACHE, and does all the necessary steps to copy in a correct way the code from flash to RAM, so now I don't know what can be wrong with the iCACHE.

Is there any other SOFTWARE consideration when changing from a nios/e to a nios/s???? My program is now working, but the execution is 210% of the nios/s (in nios/s it works for a few time. Enough to see the speed difference)

Any ideas?
