# The most advanced open source ECU has the most advanced Makefile!
# Here we do a bit of code generation, compile custom bootloader and embedded firmware and even build user artifacts!
#
# In order for Make to know which board you are trying to build for, it needs some parameters.
# BOARD_DIR - relative to the firmware dir, will be set to config/boards/f407-discovery if left empty
# SHORT_BOARD_NAME - will be set to f407-discovery if left empty
# PROJECT_BOARD - will be set to SHORT_BOARD_NAME if left empty
#
# You can set these as environment variables like this:
# source config/boards/common_script_read_meta_env.inc config/boards/f407-discovery/meta-info.env
#
# There is also a script to compile the firmware to avoid messing with your environment variables.
# ./bin/compile.sh config/boards/f407-discovery/meta-info.env
# Or to package the bundles:
# ./bin/compile.sh -b config/boards/f407-discovery/meta-info.env
# If not provided with a path to a meta-info file, compile.sh will let you select a target.
#
# If you wish to call make directly, here are the available commands:
#
# make docs-enums	Generate docs and enums
# make config			Generate docs, enums, and configs
# make						Generate docs, enums, configs, and build firmware
# make bundle			Generate docs, enums, configs, built bootloader, build firmware, and package both full and autoupdate bundles
#
# You can make a single bundle by passing the target bundle path, for example:
# make ../artifacts/rusefi_bundle_f407-discovery.zip
# make ../artifacts/rusefi_bundle_f407-discovery_autoupdate.zip
#
# You can make the bootloader either by going in to the bootloader subdirectory and running make, or by passing a bootloader target:
# make bootloader/blbuild/openblt_f407-discovery.bin
