how to get sheer machine code?

[Altera_Forum]

Dear NIOS2 Users, 

 My last post seems to be not in the forum anymore. That's why I post it one more time.  I would like to write code for NIOS2 processor in sheer assembler. Having the code compiled I can store it easily in my on-chip memory.  However, when I try compiling example code:  .section .reset, "ax" .section .exceptions, "ax" .global exception_handler .text .global _start _start: /* start function */ br _start .data .end  instead of receiving only one jmp opcode (a few bytes) in my output file I receive around 900 bytes.   I compile my code using: nios2-elf-as -ad %1.s -o a.out nios2-elf-ld a.out --strip-all --strip-debug -o %1.elf -b binary  For x86 users: I would like to get the same result like using /t with tasm assembler.  Please help me solving the problem. Thank you for your help in advance, Michał

What does nios2-elf-size <your ELF> return? In this case, the size of the ELF (itself) is not really relevant since it contains more than what would be stored in memory.

You will need to use nios2-elf-objcopy tool to convert the ELF formatted file into raw machine code. Set the target format to raw. The help and manual for that tool probably contains an example, because that is a common operation. 

 Reply if you have problems and the manual doesn&#39;t help enough.
