Thanks a lot
Sorry. I am not at all profi in this area. I may ask silly questions.
this is the memory map of the stm32f407 on the discovery board from its datasheet
and the following is the icf file that I may use
Code: Select all
/*###ICF### Section handled by ICF editor, don't touch! ****/
/*-Editor annotation file-*/
/* IcfEditorFile="$TOOLKIT_DIR$\config\ide\IcfEditor\cortex_v1_0.xml" */
/*-Specials-*/
define symbol __ICFEDIT_intvec_start__ = 0x08000000;
/*-Memory Regions-*/
define symbol __ICFEDIT_region_ROM_start__ = 0x08000000;
define symbol __ICFEDIT_region_ROM_end__ = 0x0801FFFF;
define symbol __ICFEDIT_region_RAM_start__ = 0x20000000;
define symbol __ICFEDIT_region_RAM_end__ = 0x2001FFFF;
/*-Sizes-*/
define symbol __ICFEDIT_size_cstack__ = 0x2000;
define symbol __ICFEDIT_size_heap__ = 0x2000;
/**** End of ICF editor section. ###ICF###*/
/* Size of the IRQ Stack (Main Stack).*/
define symbol __ICFEDIT_size_irqstack__ = 0x400;
define memory mem with size = 4G;
define region ROM_region = mem:[from __ICFEDIT_region_ROM_start__ to __ICFEDIT_region_ROM_end__];
define region RAM_region = mem:[from __ICFEDIT_region_RAM_start__ to __ICFEDIT_region_RAM_end__];
define block CSTACK with alignment = 8, size = __ICFEDIT_size_cstack__ {section CSTACK};
define block IRQSTACK with alignment = 8, size = __ICFEDIT_size_irqstack__ {};
define block HEAP with alignment = 8, size = __ICFEDIT_size_heap__ {};
define block SYSHEAP with alignment = 8 {section SYSHEAP};
define block DATABSS with alignment = 8 {readwrite, zeroinit};
initialize by copy { readwrite };
do not initialize { section .noinit };
keep { section .intvec };
place at address mem:__ICFEDIT_intvec_start__ {section .intvec};
place in ROM_region {readonly};
place at start of RAM_region {block IRQSTACK};
place in RAM_region {block DATABSS, block HEAP};
place in RAM_region {block SYSHEAP};
place at end of RAM_region {block CSTACK};
where should I fit the system memory in the table above in my icf file? is the file correct? I feel the system memory is missing in the icf file now! because I can guess the flash area is ROM and the SRAM areas are RAM in Chibios icf file. but nothing corresponds to system memory or CCRAM_region (called by icf default file from IAR)
