MAXQ30 familly: How can I read from a MAXQ1850 program memory ?

Hi,

I'd like to calculate the checksum of my code section and compare it with the checksum calculated by CrossWorks.

My problem is that the MAXQ1850 is built on a Harvard architecture thus data and program buses are separated. If I locate a pointer to the beggining of my code (const int* begin_code_ptr = &__begin_CODE) it points to RAM segment (IDATA, UDATA, NOINIT sections) not in the Flash segment (STARTUP, CONST, CODE ... sections).

Do you know how I can make my pointer to point to the CODE section ?

Regards

Emilien

  const __code unsigned char *code_ptr;

  Thanks a lot, it works.

  At first I had some issues (i've not identified exactly what but, since I casted everything, it worked)

  (const __code TYP_U16 *code_ptr;

  code_ptr = (const __code TYP_U16 *)begin_code_ptr;)
