NIOS II memory utilization and nios2-elf-size

Hello,

I am using a NIOS II design with a 65kbytes on-chip memory RAM. As I need to use rather large arrays in my code (32kbytes), I am starting to worry about memory utilization.

However, even when I double the size of my largest array, the nios2-elf-size does not report any size increase, and gives me this output:

$ nios2-elf-size nios_app.elf
text data bss dec hex filename
19024 832 1040 20896 51a0 nios_app.elf

Shouldn't the size of the data or bss segments increase with the size of my arrays?

There must be a point when the size of my RAM will become a limitation, but how do I check this?

Many thanks for any input you may have,

BeB

    Nevermind... it was a silly question.

    This large array is in the stack, and therefore not showing up in the nios2-elf-size nios_app.elf report.
