# 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](https://scons.org/) 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.
