.init segment

IlConte — Thu, 16 Apr 2015 08:20:01 GMT

Dear all, I use CW 10.6 and S08PT60

I have a application divided fron application and boot

Boot from 0x1040

Application from 0x3200

My prm is

SEGMENTS /* Here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */

Z_RAM = READ_WRITE 0x0040 TO 0x00FF;

RAM = READ_WRITE 0x0100 TO 0x103F;

ROM = READ_ONLY 0x3300 TO 0xFF6F; /* 3200 - 3300 driver */

ROM1 = READ_ONLY 0x1040 TO 0x2FFF;

ROM2 = READ_ONLY 0xFF80 TO 0xFFAF;

EEPROM = READ_ONLY 0x3100 TO 0x31FF;

/* INTVECTS = READ_ONLY 0xFFB0 TO 0xFFFF; Reserved for Interrupt Vectors */

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 */

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 */

_DATA_ZEROPAGE, /* zero page variables */

MY_ZEROPAGE, INTO Z_RAM;

MY_BOOT INTO ROM1;

END

STACKSIZE 0x80

map:

*********************************************************************************************

SECTION-ALLOCATION SECTION

---------------------------------------------------------------------------------------------

.init 7 R 0x3300 0x3306 ROM

.rodata 326 R 0x3307 0x344C ROM

.text 8305 R 0x344D 0x54BD ROM

_DATA_ZEROPAGE 185 R/W 0x40 0xF8 Z_RAM

MY_BOOT 7224 R 0x1040 0x2C77 ROM1

.abs_section_ffb0 80 R 0xFFB0 0xFFFF .absSeg0

How can I move the .init segment to ROM1 segment ?

Thanks

hello Stefano,

to move the .init segment to ROM1 segment, we need:

1. define _PRESTART in ROM1 in prm file.

_PRESTART

INTO ROM1;

2. add -OnB=b to the compiler to avoid trouble.

for detail . see attached video

Have a great day,
Zhang Jun
