How to know the code size ?!

[Altera_Forum]

hey mates 

My questions are : I need to use the OnCMemo for another purpose so I should know the space occupied by the code ! How do I know my code size after building ? How to know the beginning and end @ of the code downloaded in the OnCMemo? thnx

When you compile with Eclipse in output window there is .elf size

So the reset @ of my cpu is the starting @ of the code ? the end is the start + the size of elf ?

You can run nios2-stackreport on your *elf file. It should give you the code size.  

 For example: $ nios2-stackreport hello_world.elf  Info: (hello_world.elf) 29 KBytes program size (code + initialized data). Info: 92 KBytes free for stack + heap.  It shows me that the program size is 29KBytes. I have a 128KByte onchip-memory, thus it reported I have 92KBytes for stack and heap.  You can reduce the size if you are sharing the onchip memory via nios2-bsp-editor/linker section.  Or you can just split out the onchip memory to smaller size, ie 2 64KByte memory.
