Hello everyone, I'm trying to execute bit on tutorial "My first tutorial nios II", in which I use System Building and SOPC. In SOPC add to my system also Flash memory interface (CFI). My problem is that when I go to use the flash programmer in NIOS II IDE, the console displays the following message: 

   # / bin / sh# # This file was automatically generated by the Nios II IDE Flash Programmer.# # It will be overwritten When the flash programmer options change.#    cd C :/ Users/Raffaele/Desktop/my_first_niosii/software/hello_world_0/Debug  # Creating.

hello, first of all thank you for answering. You've already read these forums and many others, but unfortunately to no avail. I ran the command suggested and the result is as follows: 

 cfi_flash_0.flash: unable to open input file Empty flash content can not be programmed or verified  Appearance your feedback about

The .flash file is not found, in Nios II command shell, type :  

 cd /cygdrive/C/Users/Raffaele/Desktop/my_first_niosii/software/hello_world_0/Debug  and then  "$SOPC_KIT_NIOS2/bin/nios2-flash-programmer" --debug --base=0x04000000" cfi_flash_0.flash

Hi, maybe look at http://www.alteraforum.com/forum/showthread.php?t=16353, you may have to write a "overridden data" : a simple file containing some charachteristics of the FLASH. 

 But I am not sure that your problem is a non-recognized FLASH (you are using a custom board ?). You got stange data at the first CFI QueRY.
