Quick Start

Get IronOS running on your device in minutes

1

Download firmware for your device

Visit the releases page and download the firmware file for your specific device model and language. Files are named by device (e.g., Pinecilv2.zip, TS80P.zip) with language codes in the filename.
Choose the language code that matches your preference. Multi-language builds are available for devices with sufficient flash storage.

Enter DFU/bootloader mode

Power off your device completely. Then, hold down the front button (+/A button, closest to the tip) while plugging in the USB cable to enter bootloader mode. The screen should remain blank or show a specific bootloader indicator.
  • Pinecil V1/V2: Hold front button while connecting USB
  • TS100/TS80/TS80P: Hold front button while connecting power
  • MHP30: Hold left button while connecting USB

Flash the firmware

Once in DFU mode, your device appears as a USB storage device or DFU target:Drag-and-drop method (easiest): Open your file manager and drag the .hex, .bin, or .dfu file onto the device’s storage volume.Command-line method: Use platform-specific flashing tools:
macOS/Linux
dfu-util -D firmware.dfu
Windows
# Use STM32CubeProgrammer or dfu-util from MSYS2
dfu-util.exe -D firmware.dfu
The device will automatically reboot after flashing completes.
