Dependencies

Everything needed to build and flash Fantasi on a fresh Debian/Ubuntu box. You only need the rows for what you're doing. Versions other than the ones noted are usually fine.

One-shot install (Debian/Ubuntu)

System packages:

sudo apt install build-essential make git \
                 gcc-arm-none-eabi \
                 libreadline-dev libsystemd-dev pkg-config \
                 udisks2 util-linux \
                 dfu-util bluez

Python packages (a venv or --user is fine):

pip install pyserial pyusb pexpect nanopb pyocd

Chameleon Ultra flashing also needs nrfutil (a separate vendor binary); once it's installed:

nrfutil install device nrf5sdk-tools

Building firmware

Dependency	Required	Purpose / install
`arm-none-eabi-gcc` + binutils	yes	Cross-compiler for all three firmwares. `sudo apt install gcc-arm-none-eabi`, or put an upstream Arm GNU Toolchain `bin/` on your PATH (verified against 14.3.Rel1).
GNU `make`	yes	Build driver. `sudo apt install make`
`git`	yes	`make` auto-clones TinyUSB + LittleFS on demand. `sudo apt install git`

TinyUSB and LittleFS are fetched on the first build; every other third-party library is vendored in-tree.

Flashing

make flash (auto-detect) or make PLATFORM=<target> flash drives these via tools/flash.py.

Target	Tool	Install
Flipper Zero / Kiisu (STM32WB55)	`dfu-util`	`sudo apt install dfu-util`
Chameleon Ultra (nRF52840)	`nrfutil` + `nrf5sdk-tools`	install nrfutil, then `nrfutil install device nrf5sdk-tools`
Proxmark3 (AT91SAM7S)	pyserial	`pip install pyserial`

The STM32WB BLE radio-stack flasher (tools/radio_flash.py) needs pyusb (it talks to the ROM DFU over USB, not a serial port).

Python

Dependency	Required	Notes
Python 3	yes	3.9+. Runs `tools/flash.py`, `tools/radio_flash.py`, and `tools/launch.py`.
`pyserial`	flashing	Proxmark3 flasher
`pyusb`	some tools	WebUSB vendor-pipe helpers; also `tools/radio_flash.py`
