## tinyuf2
Keyboards may opt into supporting the tinyuf2 bootloader. This is currently only supported on the F411 blackpill.
The `rules.mk` setting for this bootloader is `tinyuf2`, and can be specified at the keymap or user level.
To ensure compatibility with the tinyuf2 bootloader, make sure this block is present in your `rules.mk`:
```make
# Bootloader selection
BOOTLOADER = tinyuf2
```
Compatible flashers:
* Any application able to copy a file from one place to another, such as _macOS Finder_ or _Windows Explorer_.
Flashing sequence:
1. Enter the bootloader using any of the following methods:
* Tap the `RESET` keycode
* Double-tap the `nRST` button on the PCB.
2. Wait for the OS to detect the device
3. Copy the .uf2 file to the new USB disk
4. Wait for the keyboard to become available

# f411 blackpill onekey
Supported Hardware: *STM32F411CEU6 WeAct v1.3*.
To trigger keypress, short together pins *B0* and *A7*.
This variant requires the TinyUF2 bootloader to be installed. This can be downloaded from the [tinyuf2 releases page](https://github.com/adafruit/tinyuf2/releases). The F401 blackpill binary works for both F401- and F411-based blackpill devices.
Double-tap reset to enter bootloader mode. Copy the built uf2 file to the device by dragging the file to the new USB disk.
