nios2-download capabilities

When I use this command without the -I option, does it check the system ID and timestamp?

If so, is it getting that from the elf file?

What does the -I option do specifically?

If I put a random hex number after the -I then I am still able to download without any error messages, if -I is supposed to check that the current FPGA image matches, then why does this work?

    It worked the last time I used it. "-I" checks sysid and "-t" checks the timestamp. I assume you have a sysid component in your Qsys system, correct? You also need to specify the "-s" option: base address of sysid component.

    [UPDATE] Also note that you have to monitor the return codes. See "nios2-download --help" for more information.

    Good luck!

    Hi, slacker.

    I had looked at the help, but didn't notice/realise that I had to specify the base address to get it to work. That address also enables the timestamp checking too.

    Thanks,
