Hi Rick,
Here is an example:
/* This is a linker parameter file for the mc13234c */
NAMES END /* CodeWarrior will pass all the needed files to the linker by command line. But here you may add your own files too. */
SEGMENTS /* Here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */
Z_RAM = READ_WRITE 0x0080 TO 0x00FF;
RAM = READ_WRITE 0x0100 TO 0x147F;
/* unbanked FLASH ROM */
ROM = READ_ONLY 0x2080 TO 0x7FFF;
ROM1 = READ_ONLY 0xC000 TO 0xFFAD;
ROM2 = READ_ONLY 0xFFC0 TO 0xFFCB;
/* INTVECTS = READ_ONLY 0xFFCC TO 0xFFFF; Reserved for Interrupt Vectors */
/* banked FLASH ROM */
PPAGE_0 = READ_ONLY 0x008000 TO 0x00A07F; /* PAGE partially contained in ROM segment */
PPAGE_2 = READ_ONLY 0x028000 TO 0x02BFFF;
PPAGE_4 = READ_ONLY 0x048000 TO 0x04BFFF;
/* PPAGE_1 = READ_ONLY 0x018000 TO 0x01BFFF; PAGE already contained in segment at 0x4000-0x7FFF */
/* PPAGE_3 = READ_ONLY 0x038000 TO 0x03BFFF; PAGE already contained in segment at 0xC000-0xFFFF */
END
PLACEMENT /* Here all predefined and user segments are placed into the SEGMENTS defined above. */
DEFAULT_RAM, /* non-zero page variables */
INTO RAM;
_PRESTART, /* startup code */
STARTUP, /* startup data structures */
ROM_VAR, /* constant variables */
STRINGS, /* string literals */
VIRTUAL_TABLE_SEGMENT, /* C++ virtual table segment */
NON_BANKED, /* runtime routines which must not be banked */
DEFAULT_ROM,
COPY /* copy down information: how to initialize variables */
INTO ROM,ROM1,ROM2: /* To use "ROM1,ROM2" as well, pass the option -OnB=b to the compiler */
PAGED_ROM /* routines which can be banked */
INTO PPAGE_0,PPAGE_2,PPAGE_4,ROM1,ROM2;
_DATA_ZEROPAGE, /* zero page variables */
MY_ZEROPAGE INTO Z_RAM;
END
STACKSIZE 0x100
VECTOR 0 _Startup /* Reset vector: this is the default entry point for an application. */
The line 33 was modified to use the ROM1 and ROM2 sections, don't forget to pass the option -OnB=b to the compiler.
Hope it helps!
