   1 # common make targets for compiling fx2 firmware
   2 #
   3 # In your Makefile, define:
   4 # SOURCES: list of c files to compile
   5 # A51_SOURCES: list of any a51 files.
   6 # DEPS: list of any depedancies (like auto-generated header files) that need
   7 #       generated prior to compiling. You must provide the target definition
   8 #       for any DEPS you define.
   9 # BASENAME: name of your firmware file, i.e., myfirmware, but not myfirmware.c
  10 #
  11 # Leave these alone or redefine as necessary to customize firmware.
  12 # (Redefine after including this makefile)
  13 # VID vendor id
  14 # PID product id
  15 # LIBS optional additional libraries to link with the firmware.
  16 # SDCC build/link options
  17 #  CODE_SIZE:    Default --code-size 0x3c00
  18 #  XRAM_SIZE:    Default --xram-size 0x0200
  19 #  XRAM_LOC:     Default --xram-loc 0x3c00
  20 # BUILDDIR: build directory (default build)
  21 # These two can be changed to be blank if no device descriptor is being used.
  22 #  DSCR_AREA:    Default -Wl"-b DSCR_AREA=0x3e00"
  23 #  INT2JT:              Default -Wl"-b INT2JT=0x3f00"
  24 #
  25 # Provided targets:
  26 #
  27 # default target: creates $(BASENAME).ihx
  28 # bix: creates $(BASENAME).bix
  29 # iic: creates $(BASENAME).iic
  30 # load: uses fx2load to load firmware.bix onto the development board
  31 #  (You can customize VID/PID if you need to load the firmware onto a device that has different vendor and product id
  32 #  The default is  0x04b4, 0x8613
  33 # clean: delete all the temp files.
