Hi ,
If I generate the elf file from the Default bootcode and pagetables , I get a very small size but
after mapping the Stack pointer to SRAM , I am getting a huge HEX file.
Here is the loader file code
============================================================
MEMORY{ rom (r) : ORIGIN = 0x00000000, LENGTH = 0x3FFFF /* pageTable (rw) : ORIGIN = 0x0B000000, LENGTH = 0x3FFF */ heap (rw) : ORIGIN = 0x02001000, LENGTH = 0x1FFF /* stack(rw) : ORIGIN = 0x0B120000, LENGTH = 0xFFFF */ /* data_mem (rw) : ORIGIN = 0x02020000, LENGTH = 0xFFFF bss_mem (rw) : ORIGIN = 0x02020000, LENGTH = 0xFFFF */ ram (rw) : ORIGIN = 0x02004000, LENGTH = 0x3FFF}
SECTIONS{
/* Code starts with bootcode, then the vector table, then the * remainder of the code */ .text : { *bootcode.o(boot) *vectors.o(vectors) /* *(.text) /* remainder of code */ } > rom
.heap : { *stackheap.o(stackheap) } > heap . = ALIGN(4);
/* Data */ /* __data_start = .; */ .data : AT (_sdata ) { . = ALIGN(4); _sdata = .; *(.data) *(.data*) } > ram
I dont understand what is the Issue here.
The size of the Hex generated is 79MB.
Thanks

Thanks for the info.
I see lot many 00000000 in the hex
Is there a way I can skip adding all the 00000000 from the hex
