1 # common make targets for compiling fx2 firmware
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
11 # Leave these alone or redefine as necessary to customize firmware.
12 # (Redefine after including this makefile)
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"
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.
