I have set up my toolchain under WinXP like that:
1. downloaded codesourcery LITE g++, installed it
2. downloaded Eclipse with C/C++ support
3. downloaded GNU ARM PLUGIN for Eclipse, and installed it from Eclipse directly
after that i could see the code sourcery toolchain in my settings file, i.e. all set up fine.
now i do the following:
1. i create the empty project with some very simple main.c which adds numbers.
2. i download the version 3.5.0 peripheral access library from st.
3. i copy the following files from that library to my project folder:
stm32f10x.h
system_stm32f10x.h
core_cm3.h
and then i of course include them in project, as well as include ''stm32f10x.h'' file from the main.c file.
then i copy the following startup file from that peripheral library:
startup_stm32f10x_hd.s
i also include the basic linker script with memory mapping for HD devices.
the linker script looks like this:
MEMORY
{
sram (W!RX) : ORIGIN = 0x20000000, LENGTH = 64k
flash (RX) : ORIGIN = 0x08000000, LENGTH = 512k
}
SECTIONS
{
.text :
{
. = ALIGN(4);
_text = .;
PROVIDE(stext = .);
KEEP(*(.isr_vector))
KEEP(*(.init))
*(.text .text.*)
*(.rodata .rodata.*)
*(.gnu.linkonce.t.*)
*(.glue_7)
*(.glue_7t)
*(.gcc_except_table)
*(.gnu.linkonce.r.*)
. = ALIGN(4);
_etext = .;
_sidata = _etext;
PROVIDE(etext = .);
_fini = . ;
*(.fini)
} >flash
.data : AT (_etext)
{
. = ALIGN(4);
_sdata = .;
*(.ramfunc .ramfunc.* .fastrun .fastrun.*)
*(.data .data.*)
*(.gnu.linkonce.d.*)
. = ALIGN(4);
_edata = .;
} >sram
.ARM.extab :
{
*(.ARM.extab*)
} >sram
__exidx_start = .;
.ARM.exidx :
{
*(.ARM.exidx*)
} >sram
__exidx_end = .;
.bss (NOLOAD) : {
. = ALIGN(4);
/* This is used by the startup in order to initialize the .bss secion */
_sbss = .;
*(.bss .bss.*)
*(.gnu.linkonce.b.*)
*(COMMON)
. = ALIGN(4);
_ebss = .;
} >sram
end = .;
PROVIDE( _estack = 0x20010000 );
}
but during compile it gives me errors like:
undefined reference to _fstat etc...
in the project properties i did browse and pointed it to the .ld linker script shown above...
so what could be a problem?
