Do you just develop SW in NiosII system? Who develops NiosII in Quartus/SOPC builder?[/b]

All informatioins about modules of NiosII, including flash, SDRAM..., can be found in SOPC builder.[/b]

I told that when I open the standard reference design in SoPC builder, I found the flas adress at 0x00000000 which is not correct!

The file-- <NiosII Name>.ptf records all information about "HW" of NiosII system. Yes, of course the BASE ADDRESS. [/b]

I checked that out and you&#39;re right, I found the following

         REFDES U5
         {
            base = "0x00800000";
         }

0x00800000 is the right base adress.

<u-boot-src>/include/configs/"board".h should deal with the information manually.[/b]

That&#39;s what I found:

/*------------------------------------------------------------------------
 * MEMORY BASE ADDRESSES
 *----------------------------------------------------------------------*/# define CFG_FLASH_BASE  0x00000000    /* FLASH base addr    */# define CFG_FLASH_SIZE  0x00800000    /* 8 MByte  */# define CFG_SDRAM_BASE  0x01000000    /* SDRAM base addr    */# define CFG_SDRAM_SIZE  0x01000000    /* 16 MByte  */# define CFG_SRAM_BASE  0x02000000    /* SRAM base addr    */# define CFG_SRAM_SIZE  0x00100000    /* 1 MB      */

And again the base adress is wrong!!!!!!!!!!!!!!!!!!!!!!!!

I concluded that I got to look only in the .ptf file.
