The code in .s19 file is out of range which is defined in .ld file?

jinhui_wu · ‎09-14-2017

i develop s32k144 in s32ds.

in .ld file, i define the code range is 0x0 ~ 0x 3190,as below:

/* Specify the memory areas */
MEMORY
{
/* Flash */
m_interrupts (RX) : ORIGIN = 0x00000000, LENGTH = 0x00000400
m_flash_config (RX) : ORIGIN = 0x00000400, LENGTH = 0x00000010
m_text (RX) : ORIGIN = 0x00000410, LENGTH = 0x00003190 - 0x410

/* SRAM_L */
m_data (RW) : ORIGIN = 0x1FFF8000, LENGTH = 0x00008000

/* SRAM_U */
m_data_2 (RW) : ORIGIN = 0x20000000, LENGTH = 0x00007000
}

in .map file, i find the code arranged in the right address，as below：

.fini_array 0x0000318c 0x4
0x0000318c PROVIDE (__fini_array_start, .)
*(SORT(.fini_array.*))
*(.fini_array*)
.fini_array 0x0000318c 0x4 d:/nxp/s32ds_arm_v1.3/cross_tools/gcc-arm-none-eabi-4_9/bin/../lib/gcc/arm-none-eabi/4.9.3/armv7e-m/fpu/crtbegin.o
0x00003190 PROVIDE (__fini_array_end, .)
0x00003190 __etext = .
0x00003190 __DATA_ROM = .

.interrupts_ram
0x1fff8000 0x400
0x1fff8000 . = ALIGN (0x4)
0x1fff8000 __VECTOR_RAM__ = .
0x1fff8000 __interrupts_ram_start__ = .
*(.m_interrupts_ram)

but in .srec file,i find the code is out of the range,as belw:

in address 0x31A0 ~ 0x3AA0,what these codes means?when were they generated?how can i delete it?

if i define this area as another code area,where these codes will go?

attachment is my .ld and .map and .srec file.thanks!

Hi,

The memory starting at address 0x3190..0x3AB3 is occupied by ROM image content.

In the map file you can find symbol __DATA_ROM which is the address where ROM image of .data section is placed.

These sections are initialized by the startup routine which performs ROM-to-RAM copy.

.map file

.fini_array    0x0000318c        0x4 d:/nxp/s32ds_arm_v1.3/cross_tools/gcc...
                0x00003190                PROVIDE (__fini_array_end, .)
                0x00003190                __etext = .
                0x00003190                __DATA_ROM = .

.ld file

.data : AT(__DATA_ROM)
 {
 . = ALIGN(4);
 __DATA_RAM = .;
 __data_start__ = .; /* Create a global symbol at data start. */
 *(.data) /* .data sections */
 *(.data*) /* .data* sections */
 KEEP(*(.jcr*))
 . = ALIGN(4);
 __data_end__ = .; /* Define a global symbol at data end. */
 } > m_data

Hope it helps.

stanislav：

you are right，thx very much

The code in .s19 file is out of range which is defined in .ld file?
