NIOS II EDS compiliation program size

Altera_Forum · ‎09-17-2010

Hi all,

i am compiling a Program using NIOSII EDS 10.0SP1. My (onchip-)Memory has a size of 49152Bytes. The Compiler tells me:

Info: (cas02_PGM1.elf) 44 KBytes program size (code + initialized data).

Info: 1796 Bytes free for stack + heap.

But this are only about 46k?!? So i am missing 2kBytes...

Can anybody help me?

Thanks in advance

Paddy

So, you are using the On-Chip memory as the SDRAM for the Nios II?

In except of the 2k you are missing, can you load the hello-world programm or any other on the system you created?

Hi,

yes i am using the onchip-memory as the program-memory for my NIOS. When i modify the code (add some functions) the Complier displays the following:

Info: (cas02_PGM1.elf) 46 KBytes program size (code + initialized data).

Info: 2184 Bytes free for stack + heap.

That is what i expected (48k). Any change in my code changes the free bytes (thats o.k), but sometimes free+used bytes are not the same as the size of my memory. I can reproduce this behaviour with other programs...
