My program size will it seems overflow heap memory (KL26Z128)
c:/freescale/kds_3.0.0/toolchain/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld.exe: FSFK_KL26Z.elf section `._user_heap_stack' will not fit in region `m_data' c:/freescale/kds_3.0.0/toolchain/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld.exe: region `m_data' overflowed by 508 bytes
I tried modifying in DebugConfiguration the target platform to KL26Z256 to trick the linker in order to print size, but this does not seem to have any impact. I looked at the linker file, and it is still the one for KL26Z128, not 256

_estack = 0x20003000; /* end of m_data */
__SP_INIT = _estack;
__stack = _estack;

__stack_size = 0x0400; /* required amount of stack */
MEMORY {
m_interrupts (RX) : ORIGIN = 0x00000000, LENGTH = 0x000000C0
m_text (RX) : ORIGIN = 0x00000410, LENGTH = 0x0001FBF0
m_data (RW) : ORIGIN = 0x1FFFF000, LENGTH = 0x00004000
m_cfmprotrom (RX) : ORIGIN = 0x00000400, LENGTH = 0x00000010
}
How can I change the linker configuration so it can complete the linking and size of the program can then be printed ?
Then, which optimizations can I make to reduce heap memory consumption ?
Thanks
