    no, i'm now very boring with it. i set my reset vector in flash and other files and vectors in sdram, but the flash handle can't return the right value which i set in SOPC.

    hi,

    otis, i have the same question as you, when debug it, it can return the right value --not NULL, but when i download the flash file into flash, and run the system, the nios program can not open the flash, and returns the wrong value---NULL.
