Re: arm-elf-objcopy create a 200MB binary from a 200K elf image!!


You're right!
I use the following setup in linker script

    . = 0x0;
    .text : { *(.text)}
    . = 0xc7f0000;
    .data : { *(.data)}
    .bss SIZEOF(.data) + ADDR(.data) :
    {
 __bss_start = ALIGN(0x8);
   *(.bss)
 *(COMMON)
 end = ALIGN(0x8);
 _end = ALIGN(0x8);
 __end = ALIGN(0x8);
........


Can't I use linker script above?
(0x0 is Rom address. and c7f0000 is Ram address.)

Thanks!
