bare-metal diabdata example for TRK-MPC5604P evaluation board

[steffenrose]

I seach a small example, that inlclude the minimal hardware initialization.
I'm not able to rework the Metrowerks examples to diabdata environment.

Thank you very much.

Hi,

we use mainly CodeWarrior in case of MPC56xx devices or S32 Design Studio and Green Hills MULTI IDE in case of MPC57xx devices. Unfortunately not the Diab...

Our examples can be found here:

Thank you very much. The "biggest" problem to use and adapt your examples from the code warrior to the diab compiler is the initialization source, like

__asm void usr_init()
{
    /* Add needed hardware initializations in this function */
    nofralloc

    mflr     r30                         /* Save off return address in NV reg */

...

I did not find an equivalent to 'nofralloc'.

Hi,

nofralloc is asm directive - it says that this function will not create a stack frame:
