# Hey Emacs, this is a -*- makefile -*- # # WinARM template makefile # by Martin Thomas, Kaiserslautern, Germany # # # based on the WinAVR makefile written by Eric B. Weddington, Jörg Wunsch, et al. # Released to the Public Domain # Please read the make user manual! # # # On command line: # # make all = Make software. # # make clean = Clean out built project files. # # make program = Download the hex file to the device # # (TODO: make filename.s = Just compile filename.c into the assembler code only) # # To rebuild project do "make clean" then "make all". # # Changelog: # - 17. Feb. 2005 - added thumb-interwork support (mth) # - 28. Apr. 2005 - added C++ support (mth) # - 29. Arp. 2005 - changed handling for lst-Filename (mth) # - 1. Nov. 2005 - exception-vector placement options (mth) # - 15. Nov. 2005 - added library-search-path (EXTRA_LIB...) (mth) # - 2. Dec. 2005 - fixed ihex and binary file extensions (mth) # - 22. Feb. 2006 - added AT91LIBNOWARN setting (mth) # - 19. Apr. 2006 - option FLASH_TOOL (default lpc21isp); variable IMGEXT (mth) # - 23. Jun. 2006 - option USE_THUMB_MODE -> THUMB/THUMB_IW # - 3. Aug. 2006 - added -ffunction-sections -fdata-sections to CFLAGS # and --gc-sections to LDFLAGS. Only available for gcc 4 (mth) # - 4. Aug. 2006 - pass SUBMDL-define to frontend (mth) # - 11. Nov. 2006 - FLASH_TOOL-config, TCHAIN-config (mth) # - 28. Mar. 2007 - remove .dep-Directory with rm -r -f and force "no error" # - 24. Aprl 2007 - added "both" option for format (.bin and .hex) # Toolchain prefix (i.e arm-elf -> arm-elf-gcc.exe) TCHAIN = arm-elf #TCHAIN = arm-none-eabi #FLASH_TOOL = UVISION FLASH_TOOL = OPENOCD USE_THUMB_MODE = YES #USE_THUMB_MODE = NO # MCU name and submodel MCU = arm7tdmi-s SUBMDL = LPC2378 ## not supported in this example: ## Create ROM-Image (final) RUN_MODE=ROM_RUN ## Create RAM-Image (debugging) - not used in this example #RUN_MODE=RAM_RUN ## not supported in this example: ## Exception-Vector placement only supported for "ROM_RUN" ## (placement settings ignored when using "RAM_RUN") ## - Exception vectors in ROM: VECTOR_LOCATION=VECTORS_IN_ROM ## - Exception vectors in RAM: #VECTOR_LOCATION=VECTORS_IN_RAM # Target file name (without extension).
