    Hi jjp

    

    Thank for question, you are coming in right time, A week ago I
    placed Kinetis port on Bugzilla. 

    http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001187

    I'll appreciate if you try it and come with feedback.

    Note:You need to commit latest version from CVS as it has bugs
    1001184, 1001186 integrated.

    

    I am using official eCos 3.0 tools (-m3 of course) in order to
    maintain compatibility, but I am keen to try gcc 4.6.

    

    Regards

    Ilija

      Hi list,

      I am doing some tiny tests with k60 and I have some troubles to
      make SVC call running properly.

      Vector table is set at 0x20000000 in register SCB_VTOR, psp and
      msp have different adresses in RAM.

      I always get an HardFault after __asm__("svc 0");

    
    Check if VTOR setting is as desired, 0x20000000 should work. Also
    stack, what do you have in mlt files?

    Ilija, is it working properly for you?

      I'm using :

         -. gcc-4.6.0

    
       -. binutils-2.21.51 (patched snaphot with OS
      support for cortex-m4)

         -. zylin zy1000 (revB 1.66)

    
    Nice to see that Zylin supports Kinetis too.

    Regards
