# This version of rules.mk expects the following to be defined before
|
||
|
|
# inclusion..
|
||
|
|
### REQUIRED ###
|
||
|
|
# OPENCM3_DIR - duh
|
||
|
|
# OPENCM3_LIB - the basename, eg: opencm3_stm32f4
|
||
|
|
# OPENCM3_DEFS - the target define eg: -DSTM32F4
|
||
|
|
# ARCH_FLAGS - eg, -mthumb -mcpu=cortex-m4 -mfloat-abi=hard -mfpu=fpv4-sp-d16
|
||
|
|
# (ie, the full set of cpu arch flags, _none_ are defined in this file)
|
||
|
|
# PROJECT - will be the basename of the output elf, eg usb-gadget0-stm32f4disco
|
||
|
|
# CFILES - basenames only, eg main.c blah.c
|
||
|
|
# LDSCRIPT - full path, eg ../../examples/stm32/f4/stm32f4-discovery/stm32f4-discovery.ld
|
||
|
|
#
|
||
|
|
### OPTIONAL ###
|
||
|
|
# INCLUDES - fully formed -I paths, if you want extra, eg -I../shared
|
||
|
|
# BUILD_DIR - defaults to bin, should set this if you are building multiarch
|
||
|
|
# OPT - full -O flag, defaults to -Os
|
||
|
|
# CSTD - defaults -std=c99
|
||
|
|
# CXXSTD - no default.
|
||
|
|
# OOCD_INTERFACE - eg stlink-v2
|
||
|
|
# OOCD_TARGET - eg stm32f4x
|
||
|
|
# both only used if you use the "make flash" target.
|
||
|
|
# OOCD_FILE - eg my.openocd.cfg
|
||
|
|
# This overrides interface/target above, and is used as just -f FILE
|
||
|
|
### TODO/FIXME/notes ###
|
||
|
|
# No support for stylecheck.
|
||
|
|
# No support for BMP/texane/random flash methods, no plans either
|
||
|
|
# No support for magically finding the library.
|
||
|
|
# C++ hasn't been actually tested with this..... sorry bout that. ;)
