NIOS II Command Shell

1) In case with the "serial cable", you are refering to a USB-Blaster Cable, than you can use the Nios IDE software to download your software in the flash memory.

2) Some development boards, such as these from TerasIC have a software utility by which you can download whatever file from your PC onto the memories on your board.

3) You can of course also make a small Nios-II processor that takes input from your serial cable via a UART and fills the information in the Flash memory.

What is need to type in to IDE command shell to download the flash file to my flash memory. I had tried nios2_flash_programmer, but it says command not found. Is there an example to run like "Hello World"?

[NiosII EDS]? ....... nios2-flash-programmer.....

Can the flash file be download with the use of serial port rather through the USB Blaster cable?

I had tried using flash programmer in the IDE with just the .flash file into flash memory, but it does seem to work. What option should be used for .flash file into flash memory?

It would be helpful if I have the ability to download using Nios II Command Shell and using Nios II IDE methods.

This doesn't have the right information?

I use the NiosII Command Shell to program my FPGA This happend in 6 steps using the simple script (prog.sh).

The arguments are the .SOF file and .ELF file.

E.g: "sh prog.sh my_top.sof my_software.elf"

Below following the script code:

(try that matters to you and take care with the values wich i used for base address, sysid, ...)
