From 214941537f2211d5e2ef16e34440485d7e872d1a Mon Sep 17 00:00:00 2001 From: Perry Hung Date: Sun, 27 Feb 2011 15:49:51 -0500 Subject: Refactor linker scripts. Rename irq and exception handlers. Add common linker scripts for ram and rom. Add medium and high density libraries for libcs3. --- support/ld/common_ram.inc | 221 +++++++++++++++++++++ support/ld/common_rom.inc | 223 +++++++++++++++++++++ support/ld/libcs3-lanchon-stm32.a | Bin 10134 -> 0 bytes support/ld/libcs3-lanchon-stm32.tar.gz | Bin 2775 -> 0 bytes support/ld/libcs3_stm32_high_density.a | Bin 0 -> 9464 bytes support/ld/libcs3_stm32_med_density.a | Bin 0 -> 9464 bytes support/ld/libcs3_stm32_src/Makefile | 35 ++++ support/ld/libcs3_stm32_src/start.S | 27 +++ support/ld/libcs3_stm32_src/start_c.c | 58 ++++++ support/ld/libcs3_stm32_src/stm32_isrs.S | 235 +++++++++++++++++++++++ support/ld/libcs3_stm32_src/stm32_vector_table.S | 90 +++++++++ support/ld/maple/flash.ld | 219 ++------------------- support/ld/maple/jtag.ld | 192 ++---------------- support/ld/maple/ram.ld | 227 ++-------------------- support/ld/maple_mini/flash.ld | 218 ++------------------- support/ld/maple_mini/jtag.ld | 192 ++---------------- support/ld/maple_mini/ram.ld | 227 ++-------------------- support/ld/maple_native/flash.ld | 211 ++------------------ support/ld/maple_native/jtag.ld | 187 ++---------------- support/ld/maple_native/ram.ld | 220 ++------------------- support/ld/names.inc | 137 +++++++------ support/ld/src.zip | Bin 15774 -> 0 bytes 22 files changed, 1102 insertions(+), 1817 deletions(-) create mode 100644 support/ld/common_ram.inc create mode 100644 support/ld/common_rom.inc delete mode 100644 support/ld/libcs3-lanchon-stm32.a delete mode 100644 support/ld/libcs3-lanchon-stm32.tar.gz create mode 100644 support/ld/libcs3_stm32_high_density.a create mode 100644 support/ld/libcs3_stm32_med_density.a create mode 100644 support/ld/libcs3_stm32_src/Makefile create mode 100644 support/ld/libcs3_stm32_src/start.S create mode 100644 support/ld/libcs3_stm32_src/start_c.c create mode 100644 support/ld/libcs3_stm32_src/stm32_isrs.S create mode 100644 support/ld/libcs3_stm32_src/stm32_vector_table.S delete mode 100644 support/ld/src.zip (limited to 'support/ld') diff --git a/support/ld/common_ram.inc b/support/ld/common_ram.inc new file mode 100644 index 0000000..be83e84 --- /dev/null +++ b/support/ld/common_ram.inc @@ -0,0 +1,221 @@ +/* Linker script for STM32 (by Lanchon with Mods by LeafLabs) */ + +OUTPUT_FORMAT ("elf32-littlearm", "elf32-bigarm", "elf32-littlearm") +SEARCH_DIR(.) +/* + * Link against libgcc, libc, and libm + */ +GROUP(libgcc.a libc.a libm.a) + +/* These force the linker to search for particular symbols from + * the start of the link process and thus ensure the user's + * overrides are picked up + */ +INCLUDE names.inc + +/* STM32 vector table.
