Linking "hello world" for iMX25

[christiann]

Giving the following source code

#include <stdio.h>

/*extern void _get_reg_general(unsigned int *reg_gen);*/

void main(void)

{

   unsigned int reg_generales[12], cont;

  /* _get_reg_general(reg_generales);*/

   printf("\nRegistros de proposito general\n");

   for(cont=0; cont<13; cont++)

   {

      printf("   reg[%d]=0x%08x\n", cont, reg_generales[cont]);

   }

}

I try to compile it with the following commands

(using file command)

whatthehell.o:             ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, not stripped

dump_cpu_mix.o.arm: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, not stripped

What step have I forgot? Based on past experience this "should" have worked, but I obviously messed this up. Any hints, hopefully I have included enough information

  It would be better to apply special compiler / toolchain for bare metal applications.

In Your case Linux toolchain, intended to create Linux applications is used.

For bare-metal applications Sourcery CodeBench Lite for ARM is suitable.

Have a great day,
