## Flashing the Device
The Meshtastic Flasher will flash the latest firmware to esp32 and nrf52 devices. This is a newly developed application (as of February 1, 2022), so there may be some issues discovered as it is tested by users.
There are three steps:
- Click the "GET VERSIONS" button to get the versions available (from GitHub).
- Click the "DETECT DEVICE" button to determine the port and device variant connected.
- Click the "FLASH" button to flash the version selected, using the port selected to the device.
## Issues?
If you run into an issue, please create a ticket here: [Flasher Issues](https://github.com/meshtastic/Meshtastic-gui-installer/issues)
The code can be found at the [Meshtastic-gui-installer repo](https://github.com/meshtastic/Meshtastic-gui-installer)
## Known limitations
The following are known limitations:
- Raspberry Pi is not available, since it is arm-based and there are no pre-built libraries for [PySide](https://wiki.qt.io/Qt_for_Python)
- Ubuntu 20.04 is the version used for testing, it may work with other versions
- see [README](https://github.com/meshtastic/Meshtastic-gui-installer/blob/master/README.md) for more details
