Why do I need to use the Nios II Command Shell to run bin2flash

Hi all,

I am trying to automate a download process over jtag and need to run bin2flash and nios2-flash-programmer.

I would like to be able to call these directly but cant seem to figure out how to run these without using the Nios II command shell. Can anyone tell me how I can either call these directly or via python? or at least give me a reason why they MUST be run in this way i.e. whats the difference between the Nios command shell and a classic bash or cmd?

thanks,

Grafne

    hi.....

    the nios command shell set the paths to quartus/bin nios2/bin and pearl

    ... you need set pearl i guess.....

    cheers

    Thanks _franz,

    SO If I take a 'normal' cmd shell and add these paths to my PATH env var then there is no reason to use the Nios II command shell?

    Do you know of any documentation on what paths are defined in the shell that I may have to add to my PATH?

    Schönen Dank Franz!! :)

    A very well answered question!! I have managed to get everything I need to work so far! I was a little nervous as I had been told by a FPGA 'expert' that you MUST use the Altera shell but seems not to be the case.

    I now have a python script that completely automates the building of flash files (bin2flash) and downloads to a cyclone IV. One small issue but I will start another thread for it.

    Again, thanks for your help!
