If you download your software through JTAG (which is the case when using "Run as Nios II Hardware") you should just put all your sections to the main RAM (which is SDRAM on your project).

Hi Dixiwen,
Thanks for your concern. First, I download my software through UART (set stdin,stdout,stderr to UART) because I have rs232 cable. I read altera document, it said that if we use rs232 cable,we have to set the stdin,stdout and stderr to UART. Is it right?

If you have some sections in Flash then the nios downloader will attempt to write data to flash and will fail with a verify error.

Second, I have two sections in Flash (EPCS and CFI). I write .sof file first using EPCS. Then, I write .zip file using CFI. What do you mean by will fail with a verify error?
Thanks in advance
