#DESCRIPTION:
#   This Makefile will build the MP3 player firmware image using the SDCC
# and ASX8051 tool chain.  Note that the result of compiling, assembling
# and linking is the file PLAYER.IHX (Intel HEX), but the file that actually
# gets programmed into the flash is FLASH.HEX.  The difference is that the
# latter has been run thru the romcksum program to add a checksum for the
# power on self test.
#
#TARGETS:
#  make all	- rebuild flash.hex
#  make install	- download target using Flash Magic in batch mode
#  make clean	- delete all generated files EXCEPT flash.hex
#  make depend	- regenerate source file dependencies
#
# REVISION HISTORY:
# dd-mmm-yy	who     description

# The default target builds everything, naturally...

	$(LINK) -n -f player

#   This rule re-creates the FASTSDI.INC file.  Unfortunately ASX8051 doesn't
# support any kind of command line option to define a value, so this is the
# only way we can get the FASTSDI setting into the assembler.  Note that
# MP3DRQ.ASM is the only file that actually uses this value!

# Compile a C file...

#   Assemble an ASM file.  Note that this rule is only used for assembly
# source files (i.e. ones for which there is no C file) - SDCC automatically
# assembles the ASM files it generates...
%.rel: %.asm
	$(ASM) $(AFLAGS) $<

# Run Flash Magic and download flash.hex to the target ...
install:
	$(FM) @player.fms

#   Remove all generated files from the directory.  DO NOT, DO NOT, DO NOT
# be tempted to do a "rm *.asm" !!!!!
clean:
	rm -f *.lst *.rel *.sym *.cdb \#* *~ *.rst player.
	rm -f *.ihx temp.lnk *.map *.mem *.lib fastsdi.inc
	for i in $(CSOURCES); do \
	  rm -f $${i}.asm; \
	done

#   This clever little hack generates Makefile.dep, which contains all the
# dependencies for the source files, from the C sources.  There's no need
# to keep the dependencies up to date by hand any more!  Note that this only
# works for C files - the dependencies for the assembly sources are hard
# wired; these files only depend on PLAYER.INC anyway...
depend: 
	rm -f Makefile.dep

	for i in $(ASOURCES); do \
	  echo $${i}.rel: $${i}.asm player.inc fastsdi.inc >>Makefile.dep; \

# And these are the source file dependencies generated...
