Application PRM File

Use an offset to link the S-Record File (generated previously) to the application.

The application's PRM file places the application code at address 0x800 in ROM and copies the code to address 0x7000 in RAM. The following listing shows the PRM file.

Listing: Linker Parameter File



LINK fiborom.abs
NAMES  mystart.o fiboram.abs ansis.lib END

SECTIONS

    MY_RAM = READ_WRITE 0x5000 TO 0x53FF;

    MY_ROM = READ_ONLY  0x0600 TO 0x07FF;

PLACEMENT

    DEFAULT_ROM, ROM_VAR, STRINGS  INTO MY_ROM;

    DEFAULT_RAM                    INTO MY_RAM;

END

STACKSIZE 0x100

VECTOR 0 _Startup /* set reset vector on startup function */

HEXFILE fiboram.s1 OFFSET 0xFFFF9800 /* 0x800 - 0x7000 */

Note: The Compiler adds the offset specified in the HEXFILE command to each record in the S-Record File, and encodes the code at address 0x700 to address 0x800.

If using CodeWarrior tools, then the CodeWarrior IDE passes all the names in the NAMES...END directive directly to the linker. Ensure that the NAMES...END directive is empty.
