Hello Cris72,

Thanks for your reply.

I configure reset vector to cfi_flash offset 0x00 and exception vector to sdram offset 0x20 (working with S29AL032D 16 bit data). I'm using EPCS16 for configuration and Nios program on Flash.

My SDRAM and Flash are shared data (16 bit) and address. I can use debug->run as nios hardware to check SDRAM; it's run fine but when i program to flash, the program cannot run.

Please help me!
