Hi there, I am using eCos and am trying to map some data to a specific address in FLASH on my custom target board (ARM7TDMI core). The data is defined as unsigned char globalArchive[] __attribute__ ((section (".ivoryDataStore"))) = {0x04, 0x18, 0x00, 0x00, 0x81); I have added the following to arm.ld (linker file) #define SECTION_ivoryDataStore(_region_, _vma_, _lma_) \ .ivoryDataStore _vma_ : _lma_ \ { FORCE_OUTPUT; *(.ivoryDataStore) } \ > _region_ And have attempted to define ivoryDataStore in my memory map of the eCos config tool (1.3.1) I kind of hoped that the name would have shown up in the drop down box for Linker-defined, as it didn't I had to specify it as user defined... i.e. Name - User-defined: ivoryDataStore - Known Size: 0x2000 Final Location (VMA) - Absolute: 0xe0000 however when I compile my code I get the following : arm-elf-gcc *.o ../../API/*/*.o -L /i/eCOSbuilds/a166_install/lib/ -Ttarget.ld -nostdlib -Xlinker -Map -Xlinker mapfile.txt /tools/H-i686-pc-cygwin/arm-elf/bin/ld: warning: no memory region specified for section `.ivoryDataStore' and the following in mapfile.txt snip .gcc_except_table 0x000ab11c 0x0 0x000ab11c .=. *(.gcc_except_table) 0x000e0000 __ivoryDataStore=0xe0000 0x41000000 __reserved_vectors=0x41000000 0x41001000 .=(__reserved_vectors+0x1000) 0x41001000 __reserved_not_mapped=0x41001000 0x41008000 .=(__reserved_not_mapped+0x7000) snip .ivoryDataStore 0x41008000 0x25bc .ivoryDataStore 0x41008000 0x25bc ../../API/Ivory/globalArchive.o 0x41008000 globalArchive 0x000ab11c __rom_data_start=LOADADDR(.data) 0x4100a5bc __ram_data_end=. 0x4100a5bc PROVIDE (__ram_data_end, .) 0x4100a5bc _edata=. 0x4100a5bc PROVIDE (edata, .) 0x000ac0d8 PROVIDE (__rom_data_end, (LOADADDR(.data)+SIZEOF(.data))) .bss 0x4100a5bc 0x59eb8 What I wanted is the memory map to show 0x000e0000 0x25bc ../../API/Ivory/globalArchive.o 0x000e0000 globalArchive Would someone be kind enough to show me what I am doing wrong?
