What's the size of my nios application?

Hi all,

I have a nios system in a BeMicroMAX10 and I'm using Quartus II web v15.02. I have "Reduced device drivers" and "Small C library" checked in the BSP properties. Quartus reports, in the summary after compilation: "Total memory bits 174080/387072 (45%)". This is ,I assume, for the 20KB I set the on-chip ram to in Qsys. My main.c file is very simple as I'm learning this.

Where do I find the size of the on-chip ram for main.c or the software application? There is a summary.html but I can see the info there.

BTW I'm using Single uncompressed image with memory initial... and programming the pof to CFM0. I have no flash ip in my qsys system.

Thanks

    If you can find the elf file, you can run nios2-stackreport to look at the total program size.

    Example:

    $ nios2-stackreport *elf

    Info: (core.elf) 269 KBytes program size (code + initialized data).

    Info: 23 KBytes free for stack + heap.

    The above shown that the program size takes up 269 KBytes and I have 23KBytes remainder for stack + heap.
