FLIPPIX OS v0.5.1 — Boot Splash & Backlight Timeout

Hardware-tested display and power-saving microrelease for Flipper Zero. Adds the custom 128x64 FLIPPIX OS boot splash at maximum brightness, restores the configured brightness after three seconds, and adds backlight auto-off choices for 30 seconds, 1 minute, 2 minutes, or Never. Activity from physical buttons, BLE controls, or console output wakes the backlight and resets its timer. The LCD, OS, USB CDC, and microSD remain active while the backlight is off.

FLIPPIX OS v0.5.0-alpha — USB File Bridge

Hardware-tested alpha release for Flipper Zero. Adds the native file browser and text viewer, the bidirectional USB File Bridge, directory listing, upload/download, mkdir/delete, per-block CRC32 validation, reliable consecutive CDC sessions, and the v0.5 status-bar label. The included root filesystem already contains /bin/filebridge. Tested with a physical Flipper Zero using a byte-identical 6768-byte binary round trip.

FLIPPIX OS v0.4.0-alpha — Console Tools

Console input and usability release for Flipper Zero.

• compact v0.4 version in the status bar
• native on-screen QWERTY keyboard with highlighted selection
• optional compact 32x9 console font
• left-side quick-command menu opened with RIGHT
• shortcuts for ls, ls -l, pwd, cd /, df, and ps
• retains BLE keyboard, read-write microSD, USB CDC, charging status, and ROM DFU updates

Hardware-flashed and boot-tested on a physical Flipper Zero. Source revision: aifadetri/FLIPPIX@884ddee. This remains experimental alpha firmware.

FLIPPIX OS v0.3.1-alpha — Status Version

Status-bar version microrelease for Flipper Zero.

• displays the current compact version v0.3a beside the FLIPPIX title
• includes all BLE keyboard, command history, menu navigation, charging status,
  read-write microSD, USB CDC, display console, and USB DFU features from
  v0.3.0-alpha

Source revision: aifadetri/FLIPPIX@10efba7

BLE keyboard support requires the official STM32WB BLE Full 1.14.0 wireless
stack on CPU2. This remains experimental alpha firmware.

FLIPPIX OS v0.3.0-alpha — BLE Keyboard

Bluetooth keyboard and FLIPPIX status UI release for Flipper Zero.

Changes:

• BLE HID keyboard discovery, pairing, subscription, and console input
• stable long-running keyboard connections through accepted parameter updates
• four-entry shell command history on Up/Down
• keyboard menu navigation, Enter/OK, Esc/F1 Back, and Shift+Up/Down scrollback
• compact FLIPPIX status title
• live BQ25896 charging indicator beside the battery gauge
• existing read-write microSD, USB CDC, display console, and USB DFU support

Hardware-tested on a physical Flipper Zero with a BLE keyboard, including
continuous typing, shell commands, history, menu navigation, charging status,
read-write microSD, USB CDC, and ROM DFU update.

BLE keyboard support requires the official STM32WB BLE Full 1.14.0 wireless
stack on CPU2. This CPU1 release does not bundle or replace ST's signed CPU2
wireless firmware.

This remains experimental alpha firmware. Keep qFlipper available for stock
firmware recovery.

FLIPPIX OS v0.2.1-alpha — Menu and Safe Reboot

Minimal UI and safe-power microrelease for Flipper Zero.

Changes:

• native startup Main Menu: Console, Settings, System info, and Power
• adjustable LCD backlight
• confirmed Reboot, USB flash (ROM DFU), and Halt actions
• safe OK/BOOT0 release handling before reset
• menu navigation no longer inherits held-button repeat
• menu-driven USB firmware updates without ST-Link
• fixed build rule that now always regenerates fuzix.bin
• modern GNU Arm Thumb metadata fix for switchin

Hardware-tested on a physical Flipper Zero, including clean reboot, menu-driven
ROM DFU, USB erase/download, CDC return, display, buttons, and read-write SD.

Source revision: aifadetri/FLIPPIX@8f61801

This remains experimental alpha firmware. Keep qFlipper available for stock
firmware recovery.

FLIPPIX OS v0.2.0-alpha — Display Console

First display-enabled FLIPPIX OS release for Flipper Zero.

Highlights

• USB CDC terminal mirrored on the built-in 128x64 display
• status bar with live BQ27220 battery percentage and battery icon
• LCD backlight at 50% brightness
• 64-line console scrollback with short and held UP/DOWN presses
• automatic return to live output when a new terminal character arrives
• safe SPI2 arbitration between the display and read-write microSD
• RGB status indication for boot, CDC, activity, disconnect, and ROM DFU

Tested on physical Flipper Zero hardware, including display scrolling, button
repeat, battery readout, repeated SD access, read-write persistence, and USB DFU.

This remains experimental alpha firmware. Installing it replaces the stock
firmware; keep qFlipper available for recovery.

FLIPPIX OS v0.1.1-alpha — Hardware SPI

v0.1.1-alpha

Hardware-SPI microrelease of FLIPPIX OS for Flipper Zero.

Changes since v0.1.0-alpha

• replaced timing-sensitive software bit-banged SD transport with STM32WB55
  hardware SPI2
• uses 250 kHz during SD initialization and 8 MHz for normal transfers
• added bounded SPI flag timeouts so a peripheral fault cannot hang the kernel
• retained software-controlled microSD chip select on PC12
• tested repeated reads, read-write remount, file creation, sync, reboot, and
  persistent data on physical Flipper Zero hardware

Included

• FUZIX kernel for STM32WB55
• compatible 32 MiB read-write microSD root filesystem image
• USB CDC console
• safe ROM DFU flashing script
• automatic reboot2dfu command for later USB-only updates
• Russian and English installation guides

Tested workflow

The release was tested on physical Flipper Zero hardware: hardware-SPI boot,
repeated SD reads, read-write filesystem persistence across reboot, USB CDC,
reboot2dfu, ROM DFU enumeration as 0483:df11, complete erase/download, and
automatic return to FUZIX.

Known limitations

This is an alpha release. Most native Flipper hardware does not yet have FUZIX
drivers. Keep qFlipper available for stock firmware recovery.
