A 128b header will appear at this address (applied by * lpc313xImgCreator) and the executable code must begin at 0x1102:9080. * * The .text virtual address space begins at the same location as the physical * address space: 0x1102 8000. The virtual space is broken up into three * regions: * * PHYSICAL VIRTUAL * NAME DESCRIPTION SIZE START SIZE START * -------- -------------------------- ----- ----------- ------- ----------- * locked Pages locked in memory. 48Kb 0x1102 8000 48Kb 0x1102 8000 * paged Pages in nonvolatile store. 96Kb 0x1103 4000 384Kb 0x1103 4000 * data .data/.bss/heap. 32Kb 0x1104 c000 32Kb 0x1109 4000 * Reserved for page table 16Kb 0x1105 4000 16Kb 0x1109 c000 * -------- -------------------------- ----- ----------- ------- ----------- * 192Kb 0x1105 8000 480Kb 0x110a 0000 * * These region sizes must match the size in pages specified for each region * in the NuttX configuration file: CONFIG_PAGING_NLOCKED, CONFIG_PAGING_NVPAGED, * and CONFIG_PAGING_NDATA. * * NOTE 1: The locked region is really big here so that you can enable lots of * debug output without overflowing the locked region. 32Kb would probably be * plenty if this were a real, optimized application. * * NOTE 2: Different compilers will compile the code to different sizes. If you * get a link time error saying that the locked region is full, you may have to * re-organize this memory layout (here and in defconfig) to make the locked * region even bigger. */ MEMORY { locked (rx) : ORIGIN = 0x11029080, LENGTH = 52K - 4224 paged (rx) : ORIGIN = 0x11035000, LENGTH = 380K data (rw) : ORIGIN = 0x11094000, LENGTH = 44K } OUTPUT_ARCH(arm) ENTRY(_stext) SECTIONS { .locked : { _slocked = ABSOLUTE(.); *(.vectors) arm_head.o locked.r (.text .text.*) arm_head.o locked.r (.fixup) arm_head.o locked.r (.gnu.warning) arm_head.o locked.r (.rodata .rodata.*) arm_head.o locked.r (.gnu.linkonce.t.*) arm_head.o locked.r (.glue_7) arm_head.o locked.r (.glue_7t) arm_head.o locked.r (.got) arm_head.o locked.r (.gcc_except_table) arm_head.o locked.r (.gnu.linkonce.r.*) _elocked = ABSOLUTE(.); } >locked .init_section : { _sinit = ABSOLUTE(.); KEEP(*(.init_array .init_array.*)) _einit = ABSOLUTE(.); } > locked .ARM.extab : { *(.ARM.extab*) } > locked __exidx_start = ABSOLUTE(.); .ARM.exidx : { *(.ARM.exidx*) } > locked __exidx_end = ABSOLUTE(.); _eronly = ABSOLUTE(.); .paged : { _spaged = ABSOLUTE(.); *(.text .text.*) *(.fixup) *(.gnu.warning) *(.rodata .rodata.*) *(.gnu.linkonce.t.*) *(.glue_7) *(.glue_7t) *(.got) *(.gcc_except_table) *(.gnu.linkonce.r.*) _epaged = ABSOLUTE(.); } > paged .data : { _sdata = ABSOLUTE(.); *(.data .data.*) *(.gnu.linkonce.d.*) CONSTRUCTORS . = ALIGN(4); _edata = ABSOLUTE(.); } > data AT > locked .bss : { _sbss = ABSOLUTE(.); *(.bss .bss.*) *(.gnu.linkonce.b.*) *(COMMON) . = ALIGN(4); _ebss = ABSOLUTE(.); } > data /* Stabs debugging sections. */ .stab 0 : { *(.stab) } .stabstr 0 : { *(.stabstr) } .stab.excl 0 : { *(.stab.excl) } .stab.exclstr 0 : { *(.stab.exclstr) } .stab.index 0 : { *(.stab.index) } .stab.indexstr 0 : { *(.stab.indexstr) } .comment 0 : { *(.comment) } .debug_abbrev 0 : { *(.debug_abbrev) } .debug_info 0 : { *(.debug_info) } .debug_line 0 : { *(.debug_line) } .debug_pubnames 0 : { *(.debug_pubnames) } .debug_aranges 0 : { *(.debug_aranges) } }
