Hi all,
I am using code sourcery lite with gcc compiler. My bin file is having 8 KB of zeros at last .
And my linker script is
MEMORY
{
FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 256K
SRAM (rwx) : ORIGIN = 0x20000000, LENGTH = 64K
}
SECTIONS
{
.text :
{
KEEP(*(.isr_vector))
*(.text .text.* .gnu.linkonce.t.*)
*(.rodata .rodata.* .gnu.linkonce.r.*)
*(.eh_frame_hdr)
*(.eh_frame)
*(.ARM.extab* .gnu.linkonce.armextab.*)
*(.gcc_except_table)
*(.eh_frame_hdr)
*(.eh_frame)
. = ALIGN(4);
KEEP(*(.init))
. = ALIGN(4);
__preinit_array_start = .;
KEEP (*(.preinit_array))
__preinit_array_end = .;

__init_array_start = .;
KEEP (*(SORT(.init_array.*)))

_etext = .;
} >FLASH
/* .ARM.exidx is sorted, so has to go in its own output section. */
__exidx_start = .;
.ARM.exidx :
{
*(.ARM.exidx* .gnu.linkonce.armexidx.*)
} >FLASH
__exidx_end = .;
_flash_data = .;
.data : AT (_flash_data)
{
_data = .;
*(vtable)
*(.data*)
_edata = .;
} > SRAM
.bss :
{
_bss = .;
*(.bss*)
*(COMMON)
_ebss = .;
_end = .;
__end = .;
} > SRAM
}
/* end of allocated ram _end */
PROVIDE( _heap = _end );
/* end of the heap -> align 8 byte */
PROVIDE ( _eheap = ALIGN(ORIGIN(SRAM) + LENGTH(SRAM) - 8 ,8) );
So any one please help me to avoid those 8 KB of zeros at end of my bin fileRegards vivek
