Flipper Build Tool

FBT is the entry point for firmware-related commands and utilities. It is invoked by ./fbt in firmware project root directory. Internally, it is a wrapper around scons build system.

Requirements

Please install Python packages required by assets build scripts: pip3 install -r scripts/requirements.txt Make sure that gcc-arm-none-eabi toolchain & OpenOCD executables are in system's PATH.

NB

FBT constructs all referenced environments & their targets' dependency trees on startup. So, to keep startup time as low as possible, we're hiding construction of certain targets behind command-line options.

Invoking FBT

To build with FBT, call it specifying configuration options & targets to build. For example,

./fbt --with-updater COMPACT=1 DEBUG=0 VERBOSE=1 updater_package copro_dist

To run cleanup (think of make clean) for specified targets, add -c option.

FBT targets

FBT keeps track of internal dependencies, so you only need to build the highest-level target you need, and FBT will make sure everything they depend on is up-to-date.

High-level (what you most likely need)

fw_dist - build & publish firmware to dist folder. This is a default target, when no other are specified
updater_package - build self-update package. Requires --with-updater option
copro_dist - bundle Core2 FUS+stack binaries for qFlipper
flash - flash attached device with OpenOCD over ST-Link
flash_usb - build, upload and install update package to device over USB. Requires --with-updater option
debug - build and flash firmware, then attach with gdb with firmware's .elf loaded
debug_updater - attach gdb with updater's .elf loaded. Requires --with-updater option
debug_other - attach gdb without loading any .elf. Allows to manually add external elf files with add-symbol-file in gdb.
openocd - just start OpenOCD

Firmware targets

firmware_extapps - build all plug-ins as separate .elf files
- firmware_snake_game, etc - build single plug-in as .elf by its name
- Check out --extra-ext-apps for force adding extra apps to external build
- firmware_snake_game_list, etc - generate source + assembler listing for app's .elf
flash, firmware_flash - flash current version to attached device with OpenOCD over ST-Link
firmware_cdb - generate compilation database
firmware_all, updater_all - build basic set of binaries
firmware_list, updater_list - generate source + assembler listing

Assets

resources - build resources and their Manifest
- dolphin_ext - process dolphin animations for SD card
icons - generate .c+.h for icons from png assets
proto - generate .pb.c+.pb.h for .proto sources
proto_ver - generate .h with protobuf version
dolphin_internal, dolphin_blocking - generate .c+.h for corresponding dolphin assets

Command-line parameters

--options optionfile.py (default value fbt_options.py) - load file with multiple configuration values
--with-updater - enables updater-related targets and dependency tracking. Enabling this options introduces extra startup time costs, so use it when bundling update packages. Or if you have a fast computer and don't care about a few extra seconds of startup time
--extra-int-apps=app1,app2,appN - forces listed apps to be built as internal with firmware target
--extra-ext-apps=app1,app2,appN - forces listed apps to be built as external with firmware_extapps target

Configuration

Default configuration variables are set in configuration file fbt_options.py. Values set on command-line have higher precedence over configuration file.

You can find out available options with ./fbt -h.

Firmware application set

You can create customized firmware builds by modifying application list to be included in the build. Application presets are configured with FIRMWARE_APPS option, which is a map(configuration_name:str -> application_list:tuple(str)). To specify application set to use in a build, set FIRMWARE_APP_SET to its name. For example, to build firmware image with unit tests, run ./fbt FIRMWARE_APP_SET=unit_tests.

Check out fbt_options.py for details.
