Hi... Can you help me?
I have still some problems in programming Flash memory.
I'm using Metrowerks Codewarriors and the HCS12 CPU (the devise is the MC9S12A256BCFU with 256K of banked flash memory).
I have to program the flash memory (for the Bootloader) and I'm writing in C.
The function that I use is:
void ProgramWord( int page, int block, unsigned int prg_address, unsigned int value)
{ unsigned int* address=(unsigned int*)prg_address;
FCNFG_BKSEL=block;
PPAGE=page;
while ( FSTAT_CBEIF==0 );
*address=value;
FCMD=0x20;
FSTAT_CBEIF=1;
__asm nop;
__asm nop;
__asm nop;
__asm nop;
__asm nop;
if ( FSTAT_ACCERR==1 || FSTAT_PVIOL==1 ) flash_errors++;
}
Thank you for your help......
