[ECOS] Memory Layout for RAM startup

[Stefan Rosinger]

Hi all!

Do I a ROM section in my eCos configuration for RAM startup?

Could there any locking problem if I define my Memory Layout as follows:

#define CYGMEM_REGION_ram (0x0)
#define CYGMEM_REGION_ram_SIZE (0x001fffff)
#define CYGMEM_REGION_ram_ATTR (CYGMEM_REGION_ATTR_R | CYGMEM_REGION_ATTR_W)
#ifndef __ASSEMBLER__
extern char CYG_LABEL_NAME (__reserved_vectors) [];
#endif
#define CYGMEM_SECTION_reserved_vectors (CYG_LABEL_NAME
(__reserved_vectors))
#define CYGMEM_SECTION_reserved_vectors_SIZE (0x3000)
#ifndef __ASSEMBLER__
extern char CYG_LABEL_NAME (__reserved_vsr_table) [];
#endif
#define CYGMEM_SECTION_reserved_vsr_table (CYG_LABEL_NAME
(__reserved_vsr_table))
#define CYGMEM_SECTION_reserved_vsr_table_SIZE (0x200)
#ifndef __ASSEMBLER__
extern char CYG_LABEL_NAME (__reserved_virtual_table) [];
#endif
#define CYGMEM_SECTION_reserved_virtual_table (CYG_LABEL_NAME
(__reserved_virtual_table))
#define CYGMEM_SECTION_reserved_virtual_table_SIZE (0x100)
#ifndef __ASSEMBLER__
extern char CYG_LABEL_NAME (__reserved_for_rom) [];
#endif
#define CYGMEM_SECTION_reserved_for_rom (CYG_LABEL_NAME
(__reserved_for_rom))
#define CYGMEM_SECTION_reserved_for_rom_SIZE (0xcd00)
#ifndef __ASSEMBLER__
extern char CYG_LABEL_NAME (__heap1) [];
#endif
#define CYGMEM_SECTION_heap1 (CYG_LABEL_NAME (__heap1))
#define CYGMEM_SECTION_heap1_SIZE (0x001fffff - (size_t) CYG_LABEL_NAME
(__heap1))

so everything is in RAM.

Thx for info
Stefan
