  Hi,

  I am absulutly new to programming on Frescale uC's ( HC9S12C64 ), professionally I am developing for the win32 platform.

  I am attemting to port code which is written for GNU  to ICC. Of course I am getting all kinds of compiler errors


Porting is easy when you know what you are doing. I'm not familiar with GCC, I may only guess what all those attributes are about. 



  How would this be correct in ICC ?

  #define LOOKUP_ATTR __attribute__ ((section (".lookup")))
  #define VECT_ATTR __attribute__ ((section (".vectors")))

  extern const int cltfactor_table[1024] LOOKUP_ATTR;

^^ this looks like putting some table of constants into nondefault memory area. Well, with extern declaration (in the header probably) you shouldn't do anything, just remove LOOKUP_ATTR.

extern const int cltfactor_table[1024];


Definition is bit different. First of all create you custom memory section by putting -b linker option into Project->Options->Other Options edit box. For example

-blookup:0x1000.0x4FFF

^^ this defines area lookup from 0x1000 to 0x4FFF


Then in C source you write

#pragma text:lookup
const int cltfactor_table[1024]={1,2,3,4,5,6};
// add here more initialized const variables
#pragma text:text





   
  INTERRUPT void UnimplementedISR(void) POST_INTERRUPT;
  INTERRUPT void ISR_Ign_TimerIn(void) POST_INTERRUPT_TEXT3;


ISR's must be easier than in GCC. 1) Remove  INTERRUPT and POST_xxx, 2) add #pragma interrupt_handler <function name> to the file where ISR's are defined:


#pragma interrupt_handler UnimplementedISR
void UnimplementedISR(void)
{
...
}

#pragma interrupt_handler ISR_Ign_TimerIn
void ISR_Ign_TimerIn(void)
{
}

Edward




  TIA
