    What board did you get? (Cyclone or Stratix and what size FPGA?)

    This sounds a lot like a project that I'm working on from home (haven't got far because I'm always busy). Anyway, let me know if you have questions and I'll try to help as well.

    Cheers.

    Thank you for your replay. first ofa ll am sorry for the delay for responding. we are using NIOS II STRATIX EDITION KIT with STRATIX EP1S10F780C6 device. I would like to know how to down load the image into the board memory as i never used the board for this application. also i want to know how to retreive the image from the downloaded memory?

    thanking you

    You should give the Nios II tutorials a try. They're really quite well written and should give you a good idea of what's necessary to start app development on the Nios II processor.

    ...beyond the tutorials two suggestions for file 'upload' to the board:

    1. Modify our 'web_server' example to support HTTP POST. Actually, it does support POST, but just prints out a silly message to demonstrate it. You'd need to add the additional code to figure out that a file was coming to malloc space for the file, and then to receive it via the sockets interface. This is probably documented/exampled in other open-source web server software out there.

    2. Find the compact-flash example designs from our partner Microtronix. There is a compact-flash component that covers the hardware. I am not sure if there is file-system-read support in this, but its worth a look. This way you could copy files to CF and then copy them into Nios memory.
